[0036] The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. Several aspects of the apparatus and methods are described by various blocks, functional units, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). Depending upon particular application, design constraints or other reasons, these elements may be implemented using electronic hardware, computer program, or any combination thereof.

[0037] The electronic hardware may include micro-electronic-mechanical systems (MEMS), integrated circuits (e.g. application specific), microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), gated logic, discrete hardware circuits, printed circuit boards (PCB) (e.g. flexible PCBs), and other suitable hardware configured to perform the various functionality described throughout this disclosure, e.g. sensors, e.g. for sensing and/or registering physical properties of the environment, the device, the user, etc. Computer program shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0038] A hearing device as used herein may be, or include, a hearing aid. A hearing aid is generally adapted to improve or augment the hearing capability of a user by receiving an acoustic signal from a user’s surroundings, generating a corresponding audio signal, possibly modifying the audio signal and providing the possibly modified audio signal as an audible signal to at least one of the user’s ears. ‘Improving or augmenting the hearing capability of a user’ may include compensating for an individual user’s specific hearing loss, such as compensation for a user’s individual hearing loss via application of gain to an input signal, such as frequency dependent gain. Thus, the processor may be configured to process the input signal in accordance with a hearing loss of a specific user of the hearing device.

[0039] The “hearing device” may further refer to a device such as a hearable, an earphone or a headset adapted to receive an audio signal electronically, possibly modifying the audio signal and providing the possibly modified audio signals as an audible signal to at least one of the user’s ears. Such audible signals may be provided in the form of an acoustic signal radiated into the user’s outer ear, or an acoustic signal transferred as mechanical vibrations to the user’s inner ears through bone structure of the user’s head and/or through parts of the middle ear of the user or electric signals transferred directly or indirectly to the cochlear nerve and/or to the auditory cortex of the user.

[0040] The hearing device is adapted to be worn at least partly behind the ear of a user. This may include i) arranging a unit of the hearing device behind the ear with a tube leading air-borne acoustic signals into the ear canal or with a receiver/ loudspeaker arranged close to or in the ear canal and connected by conductive wires (or wirelessly) to the unit behind the ear, such as in a Behind-the-Ear type hearing aid, and/ or ii) arranging the hearing device partly in the pinna and/or in the ear canal of the user such as in an In-the-Ear type hearing aid or In-the-Canal type hearing aid, or iii) arranging a unit of the hearing device attached to a fixture implanted into the skull bone such as in a Bone Anchored Hearing Aid or a Cochlear Implant, or iv) arranging a unit of the hearing device as an entirely or partly implanted unit such as in a Bone Anchored Hearing Aid or a Cochlear Implant. The hearing device may be implemented in one single unit (housing) or in a number of units individually connected to each other.

[0041] The hearing device may be part of a “hearing system”, wherein the hearing system refers to a system comprising one or two hearing devices, and a “binaural hearing system” or a “bimodal hearing system” refers to a system comprising two hearing devices where the devices are adapted to cooperatively provide audible signals to both of the user’s ears either by acoustic stimulation only, acoustic and mechanical stimulation, mechanical stimulation only, acoustic and electrical stimulation, mechanical and electrical stimulation or only electrical stimulation.

[0042] The hearing system or binaural hearing system may further include one or more auxiliary device(s) that communicates with at least one hearing device, the auxiliary device affecting the operation of the hearing devices and/or benefitting from the functioning of the hearing devices. A wired or wireless communication link between the at least one hearing device and the auxiliary device is established that allows for exchanging information (e.g. control and status signals, possibly audio signals) between the at least one hearing device and the auxiliary device. Preferably, the wireless communication link between the hearing device and the auxiliary device and/or another hearing device is provided by a wireless communication link between a radio-frequency antenna of the hearing device to the auxiliary devices or to another hearing device. Auxiliary devices may include at least one of a remote control, a remote microphone, an audio gateway device, a wireless communication device, e.g. a mobile phone (such as a smartphone) or a tablet or another device, e.g. comprising a graphical interface, a public-address system, a car audio system or a music player, or a combination thereof. The audio gateway may be adapted to receive a multitude of audio signals such as from an entertainment device like a TV or a music player, a telephone apparatus like a mobile telephone or a computer, e.g. a PC. The auxiliary device may further be adapted to (e.g. allow a user to) select and/or combine an appropriate one of the received audio signals (or combination of signals) for transmission to the at least one hearing device. The remote control is adapted to control functionality and/or operation of the at least one hearing device. The function of the remote control may be implemented in a smartphone or other (e.g. portable) electronic device, the smartphone / electronic device possibly running an application (APP) that controls functionality of the at least one hearing device.

[0043] In general, a hearing device includes i) an input unit such as a microphone for receiving an acoustic signal from a user’s surroundings and providing a corresponding input audio signal, and/or ii) a receiving unit for electronically receiving an input audio signal. The hearing device further includes a signal processing unit for processing the input audio signal and an output unit for providing an audible signal to the user in dependence on the processed audio signal.

[0044] The input unit may include multiple input microphones, e.g. for providing directiondependent audio signal processing. Such directional microphone system is adapted to (relatively) enhance a target acoustic source among a multitude of acoustic sources in the user’s environment and/or to attenuate other sources (e.g. noise). In one aspect, the directional system is adapted to detect (such as adaptively detect) from which direction a particular part of the microphone signal originates. This may be achieved by using conventionally known methods. The signal processing unit may include an amplifier that is adapted to apply a frequency dependent gain to the input audio signal. The signal processing unit may further be adapted to provide other relevant functionality such as compression, noise reduction, etc. The output unit may include an output transducer such as a loudspeaker/receiver for providing an air-borne acoustic signal transcutaneously or percutaneously to the skull bone or a vibrator for providing a structure-borne or liquid-bome acoustic signal. In some hearing devices, the output unit may include one or more output electrodes for providing the electric signals such as in a Cochlear Implant.

[0045] In the figures, similar elements have been given similar reference numerals.

[0046] Radio-frequency antennas for transmission of electromagnetic radio-frequency signals are preferably designed to have an electrical size of at least one quarter of the wavelength of the transmitted signal, since this generally allows high antenna efficiency and wide bandwidth. However, many apparatuses do not have room for an antenna large enough to satisfy this condition. For a radio-frequency signal with a frequency of e.g. 100 MHz, one quarter of the wavelength equals 0.75 m. It is thus common to utilize antennas that are physically considerably smaller than one quarter of the wavelength. Such antennas are generally referred to as “electrically short” or “electrically small” antennas. The radio-frequency antenna described herein preferably is such an electrically short antenna.

[0047] Now referring to FIGS. 1A to 1C, which schematically show perspective views of a first embodiment of a hearing device 2 comprising a radio-frequency antenna 10. The radio-frequency antenna 10 comprises at least one first antenna element 12 with a plate like first surface 13, wherein the first antenna element 12 comprises an opening 4. This opening 4 may be omitted and replaced with a solid part which then is included in the antenna element, thereby providing a closed surface at the location of the opening 4. The opening 4 allows for an element 11, such as an electrical component, to be fitted better inside the hearing device housing, e.g. with a reduced overall space requirement. The element 11 is mounted on a substrate 8, which may in particular be a flex substrate. A second microphone 9, in particular a rear microphone, and a transducer 11 are arranged or mounted on the substrate 8. The substrate 8 carrying the element 11 and the second microphone 9 is not part of the antenna structure.

[0048] A first microphone 6, in particular a front microphone, of the hearing device 2 is arranged on the first surface 13 of the first antenna element 12. Preferably, the signals of the first microphone 6 may be routed in, through or to a ground connection 24 of the first antenna element 12.

[0049] On the back surface of the first antenna element 12, opposite to the first microphone 6 or rather first microphone snout 6, a part 7 of a mems microphone may be arranged. An arm structure 5 is electrically connected to a ground plane 21 of the hearing device 2 via a feed 26.

[0050] In the embodiment of FIG. 1, the hearing device 2 is a hearing aid as it is configured to process sound in order to compensate for a user’s specific hearing loss prior to providing an output signal that the user can perceive as sound.

[0051] The first antenna element 12, the arm 5 and the ground 21 together establish an antenna which functions or operates as an Inverse-F antenna structure.

[0052] A second electrically conductive antenna element 14 with a plate like second surface 15 and a third electrically conductive antenna element 16 with a plate like third surface 17 extend in a plane substantially orthogonal to the first surface 13 of the first antenna element 12. The second electrically conductive antenna element 14 extends in the lengthwise direction of the hearing device 2.

[0053] The second antenna element 14 and the third antenna element 16 are arranged at opposite sides of each other with regard to the first antenna element 12. The second antenna element 14 and the third antenna element 16 are formed as non-resonant elements. The non-resonant elements 14 and 16 may be arranged relative to the conductive material of the first antenna element 12 in order to allow for an improved focus of the electromagnetic nearfield inside the hearing device 2. The relationship of the area of the surfaces 15 and 17 of the non-resonant elements 14 and 16 to the area of the first surface 13 depends on the desired performance, it is presently preferred that the relationship between the area of the surfaces 15 and 17 of the non-resonant elements 14 and 16 to the area of the first surface 13 is in the range 1:10 to 10:1.

[0054] The non-resonant elements 14 and 16 may be used to adjust the load that the presence of the head of a user has on the radio-frequency antenna 10. Preferably, the size of the wings or elements 14 and 16 is determined such that the performance on the left ear and the right ear is substantially balanced.

[0055] The radio-frequency antenna 10 may be constructed with a single non-resonant element, two non-resonant elements, three non-resonant elements, four non-resonant elements, or even more non-resonant elements. It has been identified that at least one non-resonant element will help tune the radio-frequency antenna 10 to a desired operating frequency and/or desired bandwidth.

[0056] The assembly of the radio-frequency antenna 10 and the other components of the hearing device 2 are to be mounted in a housing (not shown) in order to protect the radio-frequency antenna 10 and the other component from the surrounding environment and to provide a pleasing look and wearing comfort for the user of the hearing device 2. Preferably, if the radio-frequency antenna 10 is arranged inside a housing of a hearing device, the first surface 13 of the first antenna element 12 is arranged at a top wall of the housing, wherein the surfaces 15 and 17 of the second antenna element 14 and the third antenna element 16 at least partly extend along a sidewall of the housing. The second antenna element 14 and the third antenna element 16 may be electrically connected to the first antenna element 12 at one spot respectively. Alternatively, the second antenna element 14 and the third antenna element 16 may have multiple connections to the first antenna element 12.

[0057] The hearing device 2 is arranged to be worn at least partly behind an ear of a user and thus is a BTE-type hearing device 2. This means that the shown components or elements are intended to be placed in a housing configured for being placed behind the pinna of a user, such as in a single housing. It is presently preferred that the housing for the radio-frequency antenna 10 may be placed behind the ear of the user. Such a housing may include a speaker, which is sometimes referred to as a receiver, placed in the housing, this configuration is often called behind-the-ear, or in a device to be placed in or at the ear canal, this configuration is often called a receiver-in-the-ear. In further instances, the housing may be connected to an implant, such as a Cochlear Implant, where sound is received by an input transducer in the housing and converted to a digital signal, which is then processed and/or transmitted to the implant.

[0058] The hearing device 2 is composed of one first part 20 and at least one further part 22, wherein the first part 20 comprises the first antenna element 12, the second antenna element 14 and the third antenna element 16. Additionally, the first part 20 may comprise a connection member connecting the housing to an in the ear housing. Preferably, the first part 20 of the hearing device 2 corresponds to a forward and/or top side of the hearing device 2 when the hearing device 2 is carried by a user in its intended position.

[0059] The first antenna element 12 is connected via a ground 24, in particular via a ground connection 24, to the plane 21 of the hearing device 2. Additionally, the first antenna element 12 is electrically connected via a feed 26.

[0060] As shown in FIG. 1, the ground 21 may be fixed to a structure of the hearing device, such as a rack or the like, by means of two fixation members configured to engage with the ground 21, or a part of the antenna, or a structure connected mechanically to the antenna. Such fixation elements or members may include a snap arrangement so that the part being held may be inserted from above and pressed down so that the snap holds the structure in place relative to e.g. the rack. The fixation members may be arranged so that they are received in an indent or grove or cut-out of the part being held. This is contemplated to hold the part in place relative to movement in the plane of the part, e.g. lengthwise or sidewise movement of the part.

[0061] FIG. 2 illustrates a perspective view of a hearing device 30 comprising a radio-frequency antenna 40. This antenna 40 is different from the antenna arrangement shown in FIGS. 1A to 1C at least in that the antenna 40 comprises two monopole antenna elements 42 and 44 which are fed in phase. The two elements 42 and 44 are positioned at the front of the hearing device 30. The antenna 40 includes a feed 26. This feed 26 is located at a center, or midpoint, of the antenna 40. The center or midpoint is located so that the distance to the left or right side of the hearing device 30 are equal.

[0062] Shown in FIG. 2, the two elements 42 and 44 are symmetrical. It is, however, possible to alter the size and/or shape of the elements so that they are not identical. This is contemplated to allow for compensating for difference in performance of the antenna when placed at the left or right side of the head of the user.

[0063] Further, on the PCB making up the antenna 40, a transducer 11 is arranged in an opening. The transducer 11 may be mounted on the surface of the ground element 13 or may protrude through an opening arranged in the ground 13 and may be connected to the printed circuit board 7 which is mounted to the rear side of the ground 13. The transducer 11 may be a telecoil, i.e. a coil configured to receive baseband modulated signals emitted from e.g. a fixed installation.

[0064] In FIG. 2, the hearing device 30 is a hearing aid as it is configured to process sound in order to compensate for a user’s specific hearing loss prior to providing an output signal that the user can perceive as sound.

[0065] In FIG. 2, a relatively long arm 46 extends downward from the ground 13, a corresponding arm extends as the opposite side, although not visible here. The arm 46 connects to a larger surface 15, here substantially rectangular in shape. The arm 46 connect at one end of the surface 15, or rather at one side of a corner of the surface 15. The two elements 42 and 44 are preferably substantially parallel. The two elements 42 and 44 may be arranged so that the distance between then decrease when seen from where the arm 46 connect to the surface 15 and to the distal end of the surface. This would establish a rhomboidal area when viewing the element 42 and the element 44 from above or below. Also, such a narrowing arrangement would accommodate well to the shape of the housing of the hearing device as this part of the hearing device is the part to be located at the top of the pinna during use of the hearing device, i.e. when at least the majority of the housing of the hearing device is placed behind the pinna of the user.

[0066] FIG. 3 shows a hearing device 50 comprising a radio-frequency antenna 60. Here, second antenna element 62 (15) and third antenna element 64 (16) are connected (28) in order to form a loop antenna element 66. The distal ends of the second antenna element 62 and the third antenna element 64 are forming one side of the loop, wherein the other side of the loop is formed by the printed circuit board 7 mounted at the rear surface of first antenna element 66. The loop antenna is fed at one arm 24 of the loop and connected to ground at another arm 26. At the loop opening a connection to an output transducer is provided for. In FIG. 3, the hearing device 50 is a hearing aid as it is configured to process sound in order to compensate for a user’s specific hearing loss prior to providing an output signal that the user can perceive as sound. As in FIG. 2, the antenna 60 is fed at feed 26 positioned in a midpoint. The midpoint may also be seen as being on or in a plane that extend through the middle of the hearing device.

[0067] In FIG. 3, a telecoil 11 extends through an opening in the first antenna element 66. Alternatively, the telecoil may be arranged on top of the ground 13.

[0068] In FIGS. 2 and 3, input transducers, such as one or more microphones, may be positioned on a part of the respective antenna. Such an arrangement could in relation to FIG. 3 e.g. be on the surface of the first antenna element 66. Similar arrangement may be achieved in relation to FIG. 2.

[0069] By having the telecoil extend through an opening of the antenna as described herein, it is contemplated that the RF antenna and the telecoil will exhibit less interference compared to arrangement where the telecoil e.g. is located at an end opposite of where the RF antenna is located.

[0070] The radio-frequency antenna as disclosed above may be used in a hearing instrument comprising an audio converter for reception of an acoustic signal and conversion of the received acoustic signal into a corresponding electrical audio signal, a signal processor for processing the electrical audio signal into a processed audio signal so as to compensate a hearing loss of a user of the hearing instrument, a transducer connected to an output of the signal processor for converting the processed audio signal into an output signal, and a transceiver for wireless data communication, wherein the transceiver is connected to the antenna unit adapted for electromagnetic field emission and/or electromagnetic field reception.

It will be further understood that the terms “includes,” “comprises,” “including,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. It will also be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element, but an intervening element may also be present, unless expressly stated otherwise. Furthermore, “connected” or “coupled” as used herein may include wirelessly connected or coupled. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. The steps of any disclosed method are not limited to the exact order stated herein, unless expressly stated otherwise.

[0090] It should be appreciated that reference throughout this specification to “one embodiment” or “an embodiment” or “an aspect” or features included as “may” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosure. Furthermore, the particular features, structures or characteristics may be combined as suitable in one or more embodiments of the disclosure. The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more.

[0091] Accordingly, the scope should be judged in terms of the claims that follow.
