The adapter body 20 includes a control unit (not shown in the figure), a wireless communication module (not shown), an audio input interface 23, a battery 24, a power input interface 25 and a power output interface 26. Among them, the audio input interface 23 is electrically connected to the control unit, and is used to be electrically connected to an audio device that does not have wireless communication and receive an audio transmission signal. The battery 24 is electrically connected to the control unit for power supply. The power input interface 25 is used to be electrically connected to a power adapter, take power from the power adapter, and supply power to the battery 24.

The control unit is used to control the operation of the entire wireless headset adapter 1. The wireless communication module transmits the audio transmission signal converted into a wireless transmission signal to the wireless headset, thereby realizing the transmission of audio signals between the audio device that does not have wireless communication and the wireless headset.

[0036] By setting an audio input interface 23 and a wireless communication module, the present application enables the user group of wireless headsets to connect to the audio device through the audio input interface 23 when facing audio and video devices without wireless connection functions, and transmit the wireless transmission signal with the wireless headset via the wireless communication module, thereby realizing audio transmission. At the same time, by setting a battery 24, a power input interface 25 and a power output interface 26, the present application enables the wireless headset adapter 1 to charge and supply power to itself, and also to supply power to the charging compartment at the same time.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the wireless headset adapter 1 includes a housing 10 , and the adapter body 20 is disposed in the housing 10 .

[0038] Specifically, the housing 10 includes an outer shell 11 and an upper cover 12. The outer shell 11 is in a cylindrical shape with one end closed, and the adapter body 20 is arranged in the outer shell 11 and at the bottom of the outer shell 11. A receiving space 13 for accommodating the charging bin is formed above the adapter body 20. The power output interface 26 partially extends into the receiving space 13 to achieve docking and power supply with the charging port of the charging bin located in the receiving space 13. An opening is also formed on the outer shell 11 to connect the receiving space 13 with the outside world so as to take out or place the charging bin. The upper cover 12 is sealed on the opening, that is, the upper cover 12, the outer shell 11 and the adapter body 20 together define the receiving space 13.

[0039] It should be understood that the references to "bottom" and "above" refer to Figure 5 Bottom, top at the angle shown.

[0040] In some other optional embodiments, the accommodating space 13 may also be formed on one side of the adapter body 20. In this case, when the two are arranged in the housing 10, the opening of the housing 11 may be arranged only on one side corresponding to the accommodating space 13, or arranged above the accommodating space 13 and the adapter body 20, so that when the opening is opened, the accommodating space 13 and the adapter body 20 are exposed to the external environment.

[0041] In this embodiment, the housing 10 is roughly in the shape of a flat cube, and the connection of each end surface is arc-shaped to ensure a good hand feel, so that its horizontal cross section is roughly elliptical or racetrack-shaped, and the two vertical cross sections passing through the two axes of the horizontal cross section are roughly rectangular or racetrack-shaped (elliptical). An opening is formed at the top of the housing 11, and the upper cover 12 is arranged at the top of the housing 11 and covers the opening. Its outer contour is adapted to the outer contour of the upper end of the housing 11 to ensure the smoothness of the overall outer contour of the housing 10 formed by the two.

[0042] In some other optional embodiments, the opening may also be formed at one end of one side of the housing 11 , or the opening may be formed on one side wall of the housing 11 , etc.

[0043] In some other optional embodiments, the shell 10 can also be in other structural arrangements such as a round cake shape, a polygonal cake shape, an irregular shape, etc.

[0044] In some embodiments, the upper cover 12 is adapted to the cover of the charging compartment, so that when the upper cover 12 is opened, the charging compartment can be opened at the same time, and the wireless headset can be directly taken out, thereby reducing the operation steps and improving the user experience.

[0045] In this embodiment, “the upper cover 12 is adapted to the cover body of the charging bin” means that the inner contour of the upper cover 12 is adapted to the outer contour of the cover body of the charging bin, so that the cover body of the charging bin can be assembled in the upper cover 12 by interference fit.

[0046] In some other optional embodiments, “the upper cover 12 is compatible with the cover body of the charging compartment” may also mean that the upper cover 12 can accommodate the charging compartment.

[0047] In some embodiments, the upper cover 12 and the outer shell 11 may be separated, rotatably connected, or detachably connected, which is not specifically limited here.

[0048] In some other optional embodiments, the upper cover 12 may not be provided, so that the opening is always open, and the charging compartment may be partially exposed or completely accommodated in the accommodating space 13.

[0049] For example Figure 2As shown, in some embodiments, the shell 10 may further include at least one hook 14, which is protruding from the outer wall of the shell 11 and is used to connect with components such as a key ring and a hook, and is formed with a hook hole for achieving the connection.

[0050] In this embodiment, the hook member 14 is disposed on the outer wall surface of the side wall at the top end of the housing 11 .

[0051] In some other optional embodiments, it may also be arranged at other positions of the upper cover 12 or the outer shell 11 .

[0052] In some embodiments, the shell 10 may also include at least one foot (not shown in the figure), which is arranged on the outer wall of the shell 11 to support the shell 10, so that the wireless headset adapter 1 can be placed upright on a flat surface such as a desktop through the foot.

[0053] Specifically, there are two supporting legs, both of which are arranged at the end of the housing 11 away from the upper cover 12 and at the same side of the end.

[0054] In some other optional embodiments, the number of the legs can also be set to one, three, four or other plurality, and can also be set on two opposite sides of the end of the shell 11 away from the upper cover 12, or on other ends (side ends) of the shell 11, or on the upper cover 12, etc.

[0055] like Figure 3 and Figure 4 As shown, in some embodiments, the adapter body 20 also includes a board body 22, and the control unit, the wireless communication module, the power input interface 25 and the power output interface 26 are all arranged on the board body 22, and the power output interface 26 is vertically arranged on the end surface of the board body 22 close to the accommodating space 13, and the battery 24 is arranged on the side of the board body 22 away from the accommodating space 13.

[0056] Now the plate body 22 is Figure 5 The upper and lower opposite sidewalls in the angle shown are defined as the first surface and the second surface, the power output interface 26 is vertically disposed on the first surface of the board 22, and the battery 24 is disposed adjacent to the second surface of the board 22. The wireless communication module is also disposed on the first surface.

[0057] In this embodiment, the board 22 is longitudinally arranged, the power input interface 25 is arranged at one end of the board 22 , and the audio input interface 23 is arranged at the other end of the board 22 , so as to be arranged outside the housing 10 .

[0058] Correspondingly, a first charging hole 112 is formed on the housing 11 for the power input interface 25 to pass through. A first clearance hole (not shown in the figure) is also formed on the housing 11 for the audio input interface 23 to pass through and realize electrical connection with an audio device without wireless connection function.

[0059] In some other optional embodiments, the power input interface 25 and / or the audio input interface 23 may also be disposed at other positions of the board body 22 , and both may also be disposed at the same end, etc.

[0060] In some embodiments, the audio input interface 23 includes a transmission connector 232 for connecting to an audio or video device that does not have a wireless connection function to achieve audio transmission.

[0061] In this embodiment, the transmission connector 232 is a 3.5 mm audio connector.

[0062] In some other optional embodiments, the transmission connector 232 may also be an audio connector of other sizes.

[0063] In some embodiments, the audio input interface 23 may further include a transmission line 231 , thereby increasing the physical connection distance of the audio input interface 23 . For situations where it is difficult to directly plug the audio input interface 23 into a device, the extended transmission line 231 may be used to avoid situations where the audio input interface 23 is unable to connect.

[0064] In this embodiment, the transmission line 231 is inserted into the first clearance hole, one end of which is fixed to the end of the plate body 22 and electrically connected to the control unit, and the other end is connected to the transmission connector 232. The transmission connector 232 is located outside the housing 11.

[0065] In some other optional embodiments, the transmission line 231 may not have a fixed relationship with the board body 22, and is only electrically connected to the control unit through a cable or the like.

[0066] For example Figure 1 and Figure 2 As shown, in some embodiments, a clearance groove 111 is formed on the shell 11 for accommodating at least a portion of the audio input interface 23 (the portion of the audio input interface 23 exposed outside the shell 10), and the clearance groove 111 is connected to the first clearance hole, so that the audio input interface 23 passing through the first clearance hole is accommodated in the clearance groove 111.

[0067] In this embodiment, the first clearance hole is set on the bottom wall of the shell 11, and the clearance groove 111 is recessed from the bottom surface of the bottom wall to its top surface, so that the exposed part of the audio input interface 23 is accommodated in the wall surface of the lower end surface of the shell 11.

[0068] In some other optional embodiments, the clearance groove 111 may also be formed on other walls of the housing 11, or formed on two walls connected to each other of the housing 11. The first clearance hole may also be formed on other walls of the housing 11.

[0069] In some embodiments, the power input interface 25 and / or the power output interface 26 can be configured as a protruding connector for plugging in, or can be configured as a recessed interface for plugging in.

[0070] It should be understood that the power input interface 25 and / or the power output interface 26 can be set to an existing interface form such as a Micro USB interface, a USB Type C interface, a Lightning interface, etc.

[0071] In this embodiment, the power input interface 25 is a recessed interface for plugging, and the power output interface 26 is a protruding connector for plugging.

[0072] In some embodiments, the wireless headset adapter 1 can be applicable to any form of existing wireless headsets such as Bluetooth wireless headsets, infrared wireless headsets, and meter-wave wireless headsets, and the wireless communication module can be correspondingly set to a corresponding existing wireless communication module.

[0073] In this embodiment, the wireless communication module is a Bluetooth module.

[0074] In some embodiments, the adapter body 20 also includes a trigger module 27 and a switch module (not shown in the figure). Among them, the trigger module 27 is electrically connected to the control unit, and is used to generate a first trigger signal when the audio input interface 23 is accommodated in the give way slot 111, and transmit the first trigger signal to the control unit; when the audio input interface 23 is located outside the give way slot 111, it generates a second trigger signal, and transmits the second trigger signal to the control unit. The switch module is electrically connected to the control unit and the wireless communication module, and is used to control the wireless communication module to be turned off when the control unit receives the first trigger signal; when the control unit receives the second trigger signal, the wireless communication module is controlled to be turned on. Then, when the audio input interface 23 is taken out of the give way slot 111 (at this time, it may be used to connect it to an audio device), the wireless communication module is synchronously turned on, and when the audio input interface 23 is electrically connected to the audio device. There is no need to manually turn on the wireless communication module, and audio transmission between the audio device and the wireless headset can be achieved. When the audio input interface 23 is placed in the give way slot 111, the wireless communication module is synchronously turned off. There is no need to manually turn off the wireless communication module, which reduces user operations and improves the user experience. It also avoids the phenomenon of power waste caused by users forgetting to turn off the wireless communication module.

[0075] Read also Figure 3 and Figure 4 In this embodiment, the trigger module 27 is a spring-type trigger switch. A first switch hole 113 is formed on the housing 11, and the trigger module 27 is inserted into the first switch hole 113. At the same time, the first switch hole 113 is located on the wall of the housing 11 defining the clearance groove 111, so that when the audio input interface 23 is located in the clearance groove 111, it can abut against the trigger module 27, so that the trigger module 27 is triggered, thereby generating a first trigger signal. When the audio input interface 23 is removed from the clearance groove 111, it is separated from the trigger module 27, and the spring-type trigger module 27 automatically rebounds to the initial state, thereby generating a second trigger signal.

[0076] Specifically, the first switch hole 113 is disposed at a position such that when the audio input interface 23 is located in the clearance slot 111 , the transmission connector 232 thereof can abut against the trigger module 27 .

[0077] In some other optional embodiments, the first switch hole 113 may also be formed at other positions, and may also abut against the transmission line 231. It should be understood that the setting position of the trigger module 27 only needs to ensure that when the audio input interface 23 is located in the clearance groove 111, it can abut against the trigger module 27, so that the trigger module 27 is triggered.

[0078] In some other optional embodiments, the trigger module 27 may not be a spring-type trigger switch, but may be an inductive trigger switch (such as a contact sensor, a photoelectric inductive switch, etc.). The selection of the trigger mode only needs to satisfy the requirement that when the audio input interface 23 is located in the make way slot 111, it generates a first trigger signal and transmits it to the control unit, and when the audio input interface 23 is located outside the make way slot 111, it generates a second trigger signal and transmits it to the control unit.

[0079] In this embodiment, the switch module is disposed on the board 22 and on the second surface of the board 22 .

[0080] In some other optional embodiments, it may also be arranged on the first surface.

[0081] In some other optional embodiments, the power input interface 25 and / or the audio input interface 23 and / or the power output interface 26 and / or the control unit and / or the wireless communication module and / or the switch module can also be set separately (not set on the board body 22), and electrically connected to other components / units / modules set on the board body 22 through cables, etc.

[0082] In some other optional embodiments, the trigger module may not be provided, and only the switch module may be provided. In this case, the switch module may be provided as a mechanical switch module only for controlling the on-off of the circuit, and the on-off of the circuit may be controlled by the user manually controlling the switch module to achieve control of the wireless communication module. In this case, it needs to be provided on the housing 10 so that the user can control it. Or it may be provided as a switch module that senses the user, and is triggered by sensing the user's touch, and then the control of the switch of the wireless communication module is achieved through the control unit. In this case, it may be provided on the housing 10 or in the housing 10.

[0083] like Figure 4 As shown, in some embodiments, the adapter body 20 further includes a display module 28, which is electrically connected to the control unit and is used to display the charging status when the power input interface 25 is electrically connected to the power adapter.

[0084] In this embodiment, the display module 28 is a 90° lamp, which is arranged on the second surface of the board 22 and is located at the end of the board 22 near the power input interface 25, and the light emission direction is toward the extension direction of the power input interface 25 (that is, the light emission direction is 90° to the setting direction of the electrical connection). The housing 11 is also provided with a display hole 114 at a corresponding position to display the display module 28. Indicating that it is now in a charging state.

[0085] In some other optional embodiments, the display module 28 may also be configured as a light guide column or the like.

[0086] In some embodiments, the adapter body 20 further includes an adapter shell 21, the board 22, the control unit, the wireless communication module, the switch module, and the battery 24 are all disposed in the adapter shell 21, and the audio input interface 23, the power input interface 25, and the power output interface 26 are respectively disposed on the adapter shell 21. The trigger module 27 is also disposed on the adapter shell 21.

[0087] In this embodiment, the plate body 22 is horizontally arranged in the adapter shell 21, and the axes of the two in the longitudinal direction are parallel, and the outer contour of the plate body 22 is adapted to the inner contour of the adapter shell 21. The adapter shell 21 is formed with a second switch hole 2111, a display slot 2112, a penetration hole 2121, a second clearance hole 2113, and a second charging hole 213. Among them, the penetration hole 2121 is formed on the upper end surface of the adapter shell 21, and is used for the power output interface 26 to pass through the accommodating space 13. The second clearance hole 2113 corresponds to the first clearance hole, and is used for the audio input interface 23 to pass through. The second charging hole 213 corresponds to the first charging hole 112, and is used for the power input interface 25 to pass through it. The display slot 2112 corresponds to the display hole 114, and is used for the display module 28 to display. The second switch hole 2111 is used for the trigger module 27 to be electrically connected to the control unit (the cable for the electrical connection between the two is passed through it).

[0088] The setting of the adapter shell 21 allows each module / unit / component to be accommodated in the shell, thereby forming a protective cover for each module / unit / component, avoiding contamination and damage due to collision, dust, etc. during placement in the charging compartment and long-term use, thereby extending the service life of the wireless headset adapter 1.

[0089] Specifically, the adapter shell 21 is longitudinally arranged at the bottom end of the outer shell 11, and its horizontal cross-section is roughly runway-shaped, which is adapted to the horizontal cross-section of the shell 10 to expand the volume inside the adapter shell 21 as much as possible, while allowing the adapter shell 21 to be positioned inside the outer shell 11 to avoid relative shaking, etc.

[0090] In some embodiments, at least one limiting member for limiting the adapter shell 21 may be further disposed inside the housing 11 .

[0091] In some embodiments, the adapter shell 21 includes a first portion 211 and a second portion 212 . The first portion 211 is also formed with an opening, and the second portion 212 covers the opening, thereby accommodating various components.

[0092] In this embodiment, the second part 212 is arranged in a plate shape, and the first part 211 is arranged in a cylindrical shape with an opening at the upper end. Each module / unit / component is placed in the first part 211 and is covered by the second part 212. The through hole 2121 is formed on the second part 212. The first part 211 and the second part 212 are both arranged in a longitudinal direction. The top of one end of the second part 212 is recessed downward to form a charging slot. When the first part 211 is covered on the second part 212, the end of the first part 211 closes the opening of the charging slot, thereby forming a second charging hole 213. The second clearance hole 2113 is formed on the bottom wall of the first part 211. The display slot 2112 is connected to the second charging hole 213 and is recessed downward along the bottom wall of the second charging hole 213.

[0093] The second switch hole 2111 is also formed on the bottom wall of the first part 211, and the second clearance hole 2113 are respectively formed at the two ends of the bottom wall of the first part 211. The bottom wall of the periphery of the second switch hole 2111 is also provided with a plug-in protrusion, and the trigger module 27 is also provided with an assembly hole, and the plug-in protrusion is interference-fitted in the assembly hole to achieve mutual fixation between the trigger module 27 and the bottom wall of the first part 211.

[0094] It should be understood that the second switch hole 2111 may not be arranged corresponding to the first switch hole 113, and its purpose of arrangement is only to realize the electrical connection between the trigger module 27 and the control unit, so it only needs to realize this purpose.
