DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In the following description, functionally similar parts carry the same reference numerals between figures. Embodiments of the invention are now described, by way of example only, with reference to the accompanying drawings.

[0021] Referring to FIGS. 1A and 1B, an inline control unit 1 of an embodiment of the invention includes a body 3, connecting cables 5 and controls 7. The inline control unit 1 is dimensioned so as to be operable by a user's hand, and may for instance take the shape shown in FIGS. 1A and 1B, however the invention is not so limited and any appropriate shape is envisaged, with further specific embodiments concerning the shape being discussed below. The inline control unit 1 typically has two connecting cables 5 which are connected respectively to the audio device it controls, such as a bidirectional communication headset with headphones or earphones and a microphone, and to the user device which receives the audio data from the audio device and outputs audio data to the audio device. The locating of the inline control unit 1 between the user device and the audio device gives rise to the term of art ‘inline’. The inline control unit 1 may be integrally and permanently connected with the audio device, such as a headset arrangement, by the cable 5. Alternatively the inline control unit 1 may be able to be connected to a variety of different audio devices, for instance by having the connecting cable 5 which leads from the inline control unit 1 to the audio device terminating in a connector for connecting to a plurality of different audio devices, such as a USB-C or any other suitable connector. The user device may for instance be a telephone, mobile phone or computing device, and may for instance be connected to a communications network such as an analogue telephone network, a digital or softphone telephony system, an internet video calling system, or a combination of thereof. Accordingly, the connecting cable 5 which leads from the inline control unit 1 to the user device may terminate in a connector for connecting to the user device, such as a USB or jack plug, or may be hardwired into the user device. However, embodiments of the invention are not limited to the specific means and type of connection to the user device or audio device. The audio device and the inline control unit 1 are typically powered by electrical power from the user device in operation. However, embodiments of the invention are not limited to any specific means of powering the inline control unit 1.

[0022] The inline control unit 1 is designed to control aspects of the audio device, the user device, or a combination thereof. For instance, as depicted in the figures, the inline control unit 1 may include controls 7 such as buttons 7A, 7B, and 7C for allowing user control of various different functionalities. For instance, controls 7A may be volume control buttons which control the audible level of sound output in the audio device, the control 7B may be a call answer/reject button for beginning or ending a bidirectional communication operation between the user device and the audio device, and the control 7C may be a mute button for muting an audio input function of the audio device such as a microphone. Alternatively, there may be an audio input device such as a microphone in the inline control unit 1 itself. The controls 7 may for instance be physical mechanical buttons, or may be touch sensitive. However, these are merely examples, and the number and type of controls 7, their location(s) and their functionalities are not limiting on embodiments of the invention. The inline control unit 1 may control functionality of the audio device, the user device, or a combination thereof, using any mechanism of control. For instance, the inline control unit 1 may include hardware and software which is capable of interoperable control of the user device and/or audio device. However, the invention is not limited to any specific mechanism of control.

[0023] In use, when the audio device and inline control unit 1 are connected to a user device, the user may manually interact with the controls 7 on the inline control unit 1 to control the associated functionality of any specific control 7 in question. For instance, the user may be made visually and/or audibly aware of an incoming call to the user device, for instance through a screen of the user device or through the audio device. The user may then for instance choose to accept the incoming call to the user device by pressing a control 7 on the inline control unit 1 such as a call answer/reject button 7B. Whilst on the call, the user may for instance further interact with other controls 7, such as volume controls 7A, to control other associated functionality of the user device and audio device.

[0024] Advantageously, inline control units 1 according to an embodiment of the invention are configured to be removably connectable to a dock 11, an example of which is shown in FIG. 2. As such, inline control units 1 according to an embodiment of the invention further include at least one means for connection allowing the inline control unit 1 to be connected to a dock such as dock 11. For instance, the inline control unit 1 may be shaped and dimensioned such that it fits within a dock 11, and for instance is designed to be retained in the dock 11 by virtue of the physical shape and dimensionality of the inline control unit 1 fitting closely, resistance fitting or interference fitting within the dock 11. Additionally or alternatively, the material the inline control unit 1 is made from may be chosen to provide connection and retention properties. For instance the material may be chosen such that it is capable of surface interactions with the dock 11, such as being high resistance, rubberized, mildly adhesive, Velcro or any suitable material. In addition to each of the above, or as an alternative, the means for connecting the inline control unit 1 to the dock may be a magnet or magnetic material. In addition to each of the above, or as a further alternative, the inline control unit 1 may be capable of connecting to a dock 11 by any suitable mechanical connection, such as a clip, clamp, retainer, spring-loaded retention connection, a plug or a socket. Regardless of the specific manner of connection, or which combination of a plurality of different means for connection, as described above, inline control units 1 according to an embodiment of the invention are capable of being physically and reversibly connected to a dock 11. For each of the above described ways of connecting and combinations thereof, mutual aspects of a dock 11 exist where appropriate, as will be described further below.

[0025] Further, in addition to each of the above described manners of connecting the inline control unit 1 to a dock 11, or as an alternative, the means of connection of the inline control unit 1 may include a connector capable of allowing bidirectional digital communication between the dock 11 and the inline control unit 1. For instance, the connector may be an electrical, optical, magnetic or any other suitable connector.

[0026] According to embodiments of the invention, the connection between the inline control unit 1 and the dock 11 as provided by the means for connection, or the combination of the plurality of means for connection, as described above, is more than merely touching or physical contact between the inline control unit 1 and the dock 11. In particular, according to embodiments of the invention the means for connection provides at least some retention and/or resistance to separation once connected.

[0027] According to an embodiment of the invention, FIGS. 1A and 1B depict a particular connection means 9, which is configured to allow the inline control unit 1 to be connected to the dock 11. The connection means 9 may for instance be located on a side of the device on which no controls 7 are located such that the controls 7 are still accessible to a user regardless of whether or not the inline control unit 1 is connected to a dock 11 by the connection means 9. For instance, as shown in FIG. 1B the connection means 9 may be located on a back of the inline control unit 1. The connection means 9 may for instance be any of the magnet, magnetic material, mechanical connection or connectors described above, or any combination thereof. For instance, the connection means 9 may be the connector capable of allowing bidirectional digital communication between the dock 11 and the inline control unit 1, as described above and as will be described further below. Additionally the connector may include a mechanical connection, or a retention means such as a magnet or magnetic material. Alternatively, the connector may be a simple mechanical connection, or a retention means such as a magnet or magnetic material.

[0028] Further, FIGS. 1A and 1B additionally depict a particular shape of the body 3 of the inline control unit 1, the shape of which may also be used as a means for connecting to the dock 11 in the manners previously described, and as will be described further below. However, the invention is not limited to any particular shape, and any appropriate shape is envisaged.

[0029] Advantageously, docks 11 according to an embodiment of the invention are configured to be removably connected to the inline control units 1 of the invention as previously described. In particular, docks 11 according to an embodiment of the invention further include at least one mutual means for connection allowing the dock 11 to be connected to the inline control unit 1 in combination with or via respective means of connection of the inline control unit 1. In particular, for each and any particular of the means of connection of the inline control unit 1, as described above, the dock 11 may include mutual means for connection. For instance, the mutual means of connection of the dock 11 may be complementary and interoperable with any of the shape, material, magnet, magnetic material, mechanical connection or connectors described above, or any combination thereof. Regardless of the specific manner of connection, or which combination of a plurality of mutual means for connection, as described above, docks 11 according to an embodiment of the invention are capable of being physically and reversibly connected to the inline control unit 1.

[0030] According to embodiments of the invention, the connection between the inline control unit 1 and the dock 11 as provided by the mutual means for connection, or the combination of the plurality of mutual means for connection, as described above, is more than merely touching or physical contact between the inline control unit 1 and the dock 11. In particular, according to embodiments of the invention the mutual means for connection provides at least some retention and/or resistance to separation once connected.

[0031] Referring to FIG. 2, there is shown a dock 11 according to an embodiment of the invention. In particular, dock 11 includes a connection means 13 which mutually connects with connection means 9 on the inline control unit 1. Accordingly, the dock 11 of embodiments of the invention advantageously allows the inline control unit 1 to be removably connected to it, for instance as shown in FIGS. 3A and 3B, and does so in a manner which allows the inline control unit 1 to continue to provide its control functionality in use, for instance whilst a user is on a phone call as described above. The dock 11 is movable by a user, but is designed and configured to remain in a single location the majority of the time, such as when in use with an inline control unit 1 connected to it. For instance, the dock 11 is intended to remain on or connected to a surface or object in use. Accordingly, the dock 11 advantageously acts as an anchor for the inline control unit 1, allowing a user to connect and disconnect the inline control unit 1 as desired, and without loss of control functionality. For instance, the dock 11 may be left by a user on a surface such as a desk, with the user able to removably attach the inline control unit 1 to the dock 11 before, during or after an active use session between the user device and the audio device. Advantageously, the dock 11 may be moved by the user to suit personal preference, for instance a user may prefer to locate the dock 11 on a different side of a desk depending on whether they are left or right handed, or a user's preferred dock 11 location may change over time. Alternatively, the dock 11 may be connected or attached to an object, such as a computer tower or computer screen casing.

[0032] Advantageously, with the inline control unit 1 and dock 11 according to an embodiment of the invention, users are able to connect the inline control unit 1 into the dock 11 in its known location such that subsequent locating of the inline control unit 1 in use is fast and simple. For instance, this is particularly beneficial whilst the user is conducting a telephone call with the connected user and audio devices and doesn't want to waste time and effort on the distraction of locating the inline control unit 1. Further, the connecting of the inline control unit 1 to the dock 11 advantageously ensures that the inline control unit 1 and associated cables 5 are not moving around in the user's environment in use, where they may become tangled with the user or surrounding objects and become dangerous or cause damage.

[0033] Further still, the modular and removable nature of the interconnection of the inline control unit 1 with the dock 11, for instance as shown in FIGS. 3A and 3B, advantageously allows a user to connect or disconnect the inline control unit 1 to the dock as desired by use or preference. For instance, a user may wish to connect the inline control unit 1 into the dock 11 whilst sitting at a desk, but may wish to disconnect the inline control unit 1 from the dock 11 when wanting to stand up but retain the control functionality of the inline control unit 1. Alternatively, in a hot-desking or call centre environment each workstation may be supplied with its own dock 11, thereby allowing different users of the workstation to choose whether to connect the inline control unit 1 into the dock 11 or not, based on personal preference. Advantageously, inline control units 1 and docks 11 according to an embodiment of the invention thereby provide additional modular optionality between the current solutions of conventional inline control units incapable of docking, and headset systems connected only to a dock with no inline control unit.

[0034] Additionally, according to an embodiment of the invention the ability to locate the inline control unit 1 into a dock 11 such that the inline control unit 1 still provides its control functionality, for instance as shown in FIGS. 3A and 3B, is particularly advantageous in providing support and stability to the inline control unit 1 which would otherwise be hanging on the cable wiring 5 in use, as is disadvantageously the case with conventional inline control units. In particular, the connecting of the inline control unit 1 into the dock 11 when located on a surface avoids the need for users to apply a two finger grip operation, or the use of two hands with one gripping and one operating the controls 7, and hence frees the user to simply use single finger operation of the controls 7. This advantageously requires fewer hands and fingers, reduced effort, reduced strength and reduced fine motor skills to operate, and is particularly beneficial for the elderly or those with disabilities. Further, the locating of the inline control unit 1 in the dock 11 removes the disadvantageous interaction of the inline control unit 1 with the user's clothing or person as it moves around on the cabling 5 in use.

[0035] Preferably, the dock 11 may include a means for resisting movement. For instance the dock 11 may be weighted to an extent which resists movement in use. For instance it may be weighted such that it resists most accidental movements by the user, but such that it may be intentionally moved by the user when desired. For example, the dock 11 may be weighted such that it resists a light tug on the cable 5 of the inline control unit 1 when it is connected to the dock 11, the force of which would otherwise have moved the dock 11. The amount of weighting can be any suitable amount such that the dock 11 generally resists movement in normal use conditions when the inline control unit 1 is connected but is still able to be moved by a user when desired. In particular, the weighting may be achieved by creating the dock 11 from a dense material, or may include inserting a weight within the body 15 of the dock 11. Alternatively, the means for resisting movements may take the form of a plastic suction cup, a clip, or for instance a reusable adhesive material of any suitable form, both of which would for instance be located on the under side of the dock 11 as shown in FIG. 3B for connection to a surface such as a desk or an object such as a computer tower or computer screen casing. Advantageously, the means for resisting movement provides further stability, ease of use and safety benefits in maintaining the dock 11 in a chosen user location and hence enhancing further the previously described advantages.

[0036] As shown in FIG. 2, the dock has a body 15 which may be of a substantially cylindrical shape. As mentioned above, the dock 11 is intended to remain substantially in a single location when in use, for instance to rest upon a desk. For example, the dock 11 may have a shape such that it sits or rests upon a desk, such as the cylindrical shape depicted in FIGS. 2, 3A, and 3B. However, the dock 11 may also be in other shapes and dimensions, and the invention is not limited in this regard. In embodiments in which the means for connecting the inline control unit 1 to the dock 11 includes aspects of the shape and dimensionality of the inline control unit 1, the dock 11 may be accordingly dimensioned so as to receive the inline control unit 1 into a mutually shaped receiving area 17, for instance in the form of a groove or cut out, into which the inline control unit 1 can be located when connected to the dock 11. For instance, the receiving area 17 may be dimensioned such that the inline control unit 1 forms a substantially seamless part of the dock 11 once connected thereto, for instance as depicted in FIGS. 3A and 3B. Advantageously, the receiving area 17 allows for secure locating and removable retention of the inline control unit 1 in the dock 11, thereby facilitating fast locating and improved ease of access for the user, and also reducing the likelihood of damage in use as the combined inline control unit 1 and dock 11 form a single integrated whole less susceptible to being damaged. For instance, in configurations in which the inline control unit 1 stands proud from the dock 11, the inline control unit 1 would be individually exposed and may be accidentally knocked by a user in a manner that would cause mechanical stress on the pivot point of the connection means 9 and 13, potentially leading to breakage. Hence the top surfaces of the dock 11 and inline control unit 1 are flush when connected, or the inline control unit 1 may be recessed within the dock 11 when connected. Further, the receiving area 17 may advantageously guide the inline control unit 1 into the dock 11 such that the connection means 9 and 13 may correctly align, thereby further reducing the likelihood of the user damaging the connection means 9, 13 through incorrect alignment. Advantageously, the receiving area 17 provides further stability and structural integrity to the combined inline control unit 1 and dock 11 in use, hence enhancing further the previously described associated advantages.

[0037] Preferably, the dock 11 may additionally include controls 19, such as buttons 19A and 19B, for allowing user control of various different functionalities of the audio device, the user device, or a combination thereof, for instance when connected to the inline control unit 1 and in a similar manner to the inline control unit 1 as described above. The dock 11 may control functionality of the audio device, the user device, or a combination thereof, using any mechanism of control. For instance, the dock 11 may include hardware and software capable of interoperable control of the user device and/or audio device. However, the invention is not limited to any specific mechanism of control used by the dock 11. The controls 19 may for instance be physical mechanical buttons, or may be touch sensitive. However, these are merely examples, and the number and type of controls 19, their location(s) and their functionalities are not limiting on embodiments of the invention. Advantageously, the controls 10 on the dock may be provided as ‘fast key’ buttons, which travel easily with little pressure applied but which still maintain a positive tactile feel, in a similar manner to keyboard keys. This provides the user with a fast, easy and known button functionality and facilitates successful user interaction with the controls 19.

[0038] The control signals generated by user interaction with the controls 19 may be transmitted and communicated to the audio and/or user device directly by means of a direct connection between the dock 11 and the user device and/or audio device, such as any suitable wired or wireless connection, such as Bluetooth™. Alternatively, the control signals generated by user interaction with the control 19 may be conveyed to the user device and/or audio device through the inline control unit 1. For instance, in addition to each of the above described manners of connecting the inline control unit 1 to the dock 11, or as an alternative, when the inline control unit 1 has a connector capable of allowing bidirectional digital communication between the dock 11 and the inline control unit 1, the dock 11 may include a mutual connector capable of allowing bidirectional digital communication for connection thereto. For instance, the mutual connector may be an electrical, optical, magnetic or any other suitable connector, as determined by interoperable compatibility with the connector of the inline control unit 1. Regardless of the specific manner of transmission, the dock 11 may therefore include the required internal hardware and software to support this functionality.

[0039] Hence, according to an embodiment of the invention as depicted in FIG. 2, the control signals generated by user interaction with the control 19 may be conveyed to the user device and/or audio device through the inline control unit 1 by the dock outputting appropriate control signals through the connection means 13. When connected to the inline control unit 1, the dock 11 may draw electrical power from the user device through the inline control unit 1 by means of the connection means 9 and 13.

[0040] Accordingly, docks 11 according to an embodiment of the invention are advantageously capable of modularly supplementing the control functionality of the inline control unit 1 with additional control functionality for the user device and/or audio device. Hence, docks 11 according to an embodiment of the invention advantageously provide additional control functionalities to the inline control unit 1 in a convenient plug and play format.

[0041] The controls 19 may provide at least one different and additional control functionality to those found on the inline control unit 1. For instance, the dock 11 may include control buttons 19A and 19B. The control buttons 19A and 19B may be user programmable, for instance it may be possible for a user to assign a control functionality to these buttons using software on, for instance, the user device. Alternatively, at least one of the control buttons such as 19A may have a specific predetermined functionality. According to an embodiment, a control 19A may be specifically designed to launch a particular softphone application, such as for instance Microsoft Teams™, Zoom™, or Skype™ etc. on the user device. Accordingly, the dock 11 may be manufactured and sold with this or any other specific control functionality assigned to one of the controls such as 19A, and may therefore include the required internal hardware and software to support this functionality. Accordingly, a range of docks 11 may be manufactured and sold separately, each providing specific control functionality associated with for instance the particular user device application or particular control functionality.

[0042] As such, docks 11 according to an embodiment of the present invention advantageously provide a cost effective manner for a user to update and supplement their control functionality over time. In particular, a user can purchase a single inline control unit 1, either as part of a headset or separately, with its predetermined range of controls 7 and will then only need to purchase new docks 11 when new applications or control functionalities are provided in the marketplace, and new docks 11 are accordingly created to accommodate these control functionalities. In this way the user is provided with a cost effective way of future proofing the purchase and use of their single inline control unit 1, as instead of needing to replace the inline control unit each time a new control functionality is desired or new application is released, the user can simply buy a supplementary dock 11 accordingly.

[0043] In use, when the inline control unit 1 is connected to the dock 11, the user may manually interact with the controls 7 on the inline control unit 1 in the same manner as previously described. Indeed, as previously described, the dock 11 of an embodiment of the present invention advantageously allows for the control functionality of the inline control unit 1 to be used even when the inline control unit 1 is connected to the dock 11. Further advantageously, the user may also manually interact with the additional controls 19 of the dock 11 to control the additional associated functionality of any specific control 19 in question. Hence, as well as the previously described advantages, the dock 11 according to an embodiment of the invention advantageously supplements the range of control functionality of the inline control unit 1 with the further additional control functionality found on the dock 11.

[0044] For instance, when the dock 11 includes application specific control functionality, such as a control 19A which launches a particular application on the user device such as Microsoft Teams™, Zoom™, or Skype™ etc., a user may simply arrive at a work station, connect their inline control unit 1 to the dock 11, and press the control 19A to quickly and efficiently launch the desired specific application on the user device. The user may then conduct a call through the specific application, and may for instance adjust the volume of the call using the controls 7A located on the inline control unit 1 located in the dock 11. Hence the user is provided with an advantageously large range of control functionality centered in the single easy to access location of the combined inline control unit 1 and dock 11.

[0045] Inline control units 1 and docks 11 according to an embodiment of the invention are particularly advantageous in the call centre or hot-desking context, and particularly in instances in which the dock 11 is manufactured and sold with application specific control functionality assigned to one of the controls such as 19A, such as for use with Microsoft Teams™, Zoom™, or Skype™ etc., and a range of docks 11 are manufactured each providing specific control functionality associated with the particular user device application. Here each user may arrive at a particular workstation bringing with them their own dock 11 of preference, and hence may modularly supplement the inline control unit 1 of the particular workstation with the additional plug and play functionality of their own dock 11 providing specific application control functionality. Hence the inline control unit 1 and dock 11 according to an embodiment of the invention is particularly advantageous in flexibly accommodating a range of user specific control preferences in a cost effective manner, in particular as the requirement to purchase an entirely new headset and inline control unit for each different control functionality and/or application is avoided.

[0046] In combination with the at least one additional and different control functionality provided by the dock 11, if a control 7 of the inline control unit 1 is obscured when connected to the dock 11—such as control 7C of the embodiment depicted in FIGS. 1A and 1B would be when located in the dock 11 of the embodiment depicted in FIG. 2 and FIGS. 3A and 3B—then one of the controls 19 may provide this same control functionality as the obscured control 7 so that the user is not deprived of this control functionality when the inline control unit 1 and dock 11 are connected. For instance, control 7C on the inline control unit 1 may have the same functionality as control 19B on the dock 11, such as a mute control.

[0047] Accordingly, an embodiment of the invention advantageously provides an inline control unit 1 for use with an audio device connected to a user device, and capable of being connected to a dock 11, for instance located on a desk. Accordingly, an embodiment of the invention advantageously allows users to overcome the disadvantages of the conventional inline control units—which for instance move around with the cable wiring, are unstable in operation, difficult for users to locate, and require two hand grip operations—whilst maintaining the useful modularity of inline controls.

[0048] Further, an embodiment of the invention may additionally provide for the dock 11 to supplement the control functionality of the inline control unit 1 with additional different control functionality, such as in embodiments in which the dock 11 includes application specific controls for launching and/or controlling a particular application on the user device. Accordingly, an embodiment of the invention advantageously allows a user to retain a single headset with an inline control unit 1 that includes the core universal functionality (e.g. volume control, call answering), which the user can choose to anchor to the dock 11 to avoid the above disadvantages, whilst simultaneously harnessing the dock 11 to supplement the core control functionality of the inline control unit 1 with additional functionality, such as dedicated application launching control buttons for applications on the user device. Hence an embodiment of the invention provides additional cost saving and convenience advantages, as instead of having to buy a new headset with new inline controls each time additional functionalities enter the market, a user can retain a single headset including the inline control unit 1 throughout its lifetime and can supplement this over time with ‘plug-and-play’ docks 11 which provide additional specific functionalities.
