DETAILED DESCRIPTION

(9) The description that follows describes, illustrates and exemplifies one or more particular embodiments of the present invention in accordance with its principles. This description is not provided to limit the invention to the embodiments described herein, but rather to explain and teach the principles of the invention in such a way to enable one of ordinary skill in the art to understand these principles and, with that understanding, be able to apply them to practice not only the embodiments described herein, but also other embodiments that may come to mind in accordance with these principles. The scope of the present invention is intended to cover all such embodiments that may fall within the scope of the appended claims, either literally or under the doctrine of equivalents.

(10) FIG. 1 illustrates a front view of an exemplary portable auxiliary unit 100, in accordance with a particular embodiment of the present invention. The portable auxiliary unit (which may also be called auxiliary unit or simply unit herein), may come in a variety of different sizes, shapes, and configurations to accommodate different forms of mobile audio player. As shown herein, the exemplary unit has been developed to support an Echo Dot device made by Amazon. However, it will be understood from the figures and description how the auxiliary unit could be reconfigured (primarily by forming the receiving cup 160 in a different shape) to accommodate a variety of other types of mobile audio players.

(11) As shown in FIG. 1, the exemplary auxiliary unit 100 rests on a base stand 170 at its bottom and has a receiving cup 160 at its top. As illustrated more clearly in FIG. 2, the receiving cup 160 is configured to receive a mobile audio player, in this case, audio player 200. Specifically, as illustrated, receiving cup 160 features a seat 162 on which the audio player 200 rests when installed, a cylindrical wall 164 that forms a perimeter round the outside of the audio player 200, and a lip 166 that extends outward from the top of the cylindrical wall 164. As illustrated in FIG. 3, the lip is used to support the receiving cup 160 at the top of the portable auxiliary unit 100 by resting on the upper portion of the outer casing 180. Thus, when audio player 200 is installed in the receiving cup 160, the cup encapsulates the audio player on all but its open top surface, and provides protection from impact, as well as some protection from moisture and dust. Additional protection may be provided by placing a lid over the receiving cup (not shown) to fully encapsulate the audio player 200.

(12) The outer casing 180 extends from the lip 166 of the cup 160 down to the base stand 170, thereby forming an outer perimeter (side walls) of the auxiliary unit 100. At its top is a frame ring 180 to provide structure prior to assembly of the cup 160. The outer casing 180 may be made of various materials, but should allow for the clear passage of sound. In some embodiments, the casing may simply comprise a frame wrapped in a fabric or plastic mesh material. As shown on FIG. 1, the outer casing is interrupted at the front side of the unit 100 by an access panel 150 and a user interface 110. The user interface 110 features a power button 120 for powering on or off the auxiliary unit 100, a fixed audio input slot 130, and a fixed power input slot 140. The fixed audio input slot 130 is for receiving audio input from an external source other than audio player 200, such as, for example, a different type of mobile audio player. The fixed power input slot is to receive line power (stepped down via an adapter) for use in recharging the internal rechargeable battery pack 142.

(13) The access panel 150 provides access to the controls of the audio player 200, specifically, audio player power input 205 and audio player audio output 210, when audio player 200 is installed in receiving cup 160. Access panel 150 is illustrated in a closed configuration in FIG. 1. The panel can be peeled back to an open configuration using tab 152 when audio player 200 is installed, or simply by pressing outward from the inside of the receiving cup 160 when the audio player 200 is absent. Receiving cup 160 features an access port 168 (best shown in FIG. 3) that aligns with the access panel 150 to facilitate opening the access panel 150 in the absence of audio player 200, but primarily to facilitate access to the audio player controls when audio player 200 is installed.

(14) Turning to FIG. 4, on its inside, access panel 150 features a seal extension 154 and two fastener plugs 156. The fastener plugs 156 correspond to receiving holes 181 formed in the outer casing 180 to secure the access panel 150 closed. The seal extension provides additional retention by seating up against a cutout 183 in the outer casing. At its lower end, the access panel 150 is jointed, and secured to the outer casing 180. The panel 150 may be rigid, such as plastic, or flexible, such as rubber.

(15) Once the access panel is peeled back into an open configuration (FIG. 3), audio connection cable 134 and power connection cable 144 are revealed. These cables each feature plugs (audio plug 135 and power plug 145) that are configured to insert into audio player power input 205 and audio player audio output 210, respectively. The cables are each tethered permanently to the auxiliary unit 100, and extend down into an internal housing 182 where the power cable 144 connects to the rechargeable battery pack 142 and the audio cable 134 connects to a speaker assembly 132. The upper ends that feature the plugs are unfixed, and provide sufficient mobility to be manipulated into and out of the audio player 200 but have short enough cable lengths to secure within the outer casing 180 when access panel 150 is closed.

(16) As shown, in operation, audio player 200 is positioned above receiving cup 160 so that its controls align with the access panel 150, and is lowered into the cup. Access panel 150 is peeled back and the plugs are inserted into the controls as indicated (audio plug 135 into audio output 210 and power plug 145 into power input 205). Then, access panel 150 is closed. At this point, provided the unit 100 is powered on and sufficiently charged, the audio player will receive auxiliary power from rechargeable battery pack 142 and will deliver audio signals through audio connection cable 135 to speaker assembly 132.

(17) FIGS. 5-7 illustrate internal components of exemplary auxiliary unit 100. Specifically, the outer casing 180 has been pulled away to reveal an internal housing 182 that provides a support framework for internal components such as speaker assembly 132 and rechargeable battery pack 142. FIG. 5 shows a left side view of the unit 100, with the front side and its user interface 110 on the right and the speaker assembly 132 on the left. FIG. 6 shows a front view, directly facing user interface 110. The controls and cables are physically separated from the speaker assembly 132 and the rechargeable battery pack 142 by divider 190, which forms the front wall of internal housing 182. However, the power features are electrically connected to the battery pack 142, and the audio features are electrically connected to the speaker assembly 132, through a whole in divider 190 near its base.

(18) FIG. 7 shows a rear view of the internal components, again with the outer casing 180 removed. This is the opposite side of the divider 190 from FIG. 6. Here, the speaker assembly 132 can be seen mounted in conjunction with the rechargeable battery pack 142. In this embodiment, the speaker assembly includes two separate drivers, but may be more or less complicated or powerful in other configurations. The rechargeable battery pack can be configured with an internal adaptor, or even a switch to step power to different output levels for different devices, as set by the user. Speaker volume is dictated by output level of the audio player 200, but the auxiliary unit may have separate volume controls in some configurations.

(19) Accordingly, it should now be clear how the present invention enhances the performance, volume, sound quality, and playback time of a common mobile audio player. The invention allows for longer playback for a larger group of people for stored or streamed audio where line power is not available or easily accessible. The unit is mobile and lightweight, yet provides sufficient protection for the audio player. The access panel and cabling also provide for ease of access/hookup and disassembly of the audio player to the auxiliary unit.

(20) It should be emphasized that the above-described exemplary embodiments of the present invention, and particularly any exemplary embodiments, are possible examples of implementations, merely set forth for a clear understanding of the principles of the invention. Many other variations and modifications may be made to the above-described embodiments of the invention without substantially departing from the spirit and principles of the invention. All such modifications are intended to be included herein within the scope of this disclosure and the present invention and protected by the following claims.
