Description

Technical Field

[0001] This application relates to the field of audio guides, specifically to a charging case and a charging base for binaural receivers. Background Technology

[0002] Wireless audio guide systems are often used in museums, scenic spots, conferences, and other similar settings to provide richer explanations and information. The core components of this system are the audio guide and the receiver, which work together to transmit the guide's voice or pre-recorded audio signals to the audience.

[0003] The audio guide is essentially a miniature broadcasting station, responsible for converting the guide's voice or pre-recorded audio signals into wireless signals for transmission. The receiver is responsible for receiving the wireless signals transmitted by the audio guide and converting them back into sound for the audience to listen to.

[0004] Receivers come in many types, and ear-hook receivers are gradually becoming the preferred choice for users due to their advantages such as portability, comfort, and hands-free operation. However, with the widespread use of binaural ear-hook receivers, existing charging technologies can no longer meet users' growing demands for convenient charging and device compatibility. This is mainly reflected in the fact that most existing charging solutions are designed for single-ear ear-hook receivers and cannot be adapted to binaural ear-hook receivers simultaneously. Users need to use two different charging docks to charge the left and right ear receivers separately, which is cumbersome and inefficient.

[0005] The aforementioned technical defects severely impact the user experience and hinder the further development of wireless navigation systems. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] like Figure 1 As shown, the binaural receiver 200 includes a left ear receiver 210 and a right ear receiver 220; the left ear receiver 210 and the right ear receiver 220 are mirror-symmetrical, and the user can choose to wear one of the left ear receiver 210 and the right ear receiver 220 as needed, or wear both of the left ear receiver 210 and the right ear receiver 220 at the same time; the left ear receiver 210 and the right ear receiver 220 each have two first magnetic contacts (not shown) and two first charging contacts 230, and both the left ear receiver 210 and the right ear receiver 220 can be magnetically attracted to the matching charging base 100 through the first magnetic contacts and charged through the first charging contacts 230.

[0031] Furthermore, in Figure 1 In the middle, both the left ear receiver 210 and the right ear receiver 220 have a protruding sound-emitting part 240, which transmits audio to the user.

[0032] like Figures 2A to 2DAs shown, in one embodiment of the charging dock 100 for the binaural receiver 200, the charging dock 100 can charge the aforementioned... Figure 1 The left ear receiver 210 can charge the right ear receiver 220 separately. Specifically, the charging base 100 includes a base body 10, two second magnetic contacts 20, and two second charging contacts 30. The base body 10 has a charging contact surface 11 adapted to the left ear receiver 210 and the right ear receiver 220. The two second magnetic contacts 20 are symmetrically arranged on the charging contact surface 11. The two second charging contacts 30 are symmetrically arranged on the charging contact surface 11. The left ear receiver 210 and the right ear receiver 220 contact the charging contact surface 11 in an alternative manner, so that the first magnetic contact and the second magnetic contact 20 are attracted together, and the first charging contact 230 contacts the second charging contact 30.

[0033] In this embodiment, of the two first charging contacts 230 of the left ear receiver 210 or the right ear receiver 220, one first charging contact 230 is the positive terminal and the other first charging contact 230 is the negative terminal. Similarly, one second charging contact 30 of the charging base 100 is the positive terminal and the other second charging contact 30 is the negative terminal. During the charging process, the positive terminals are in contact with each other and the negative terminals are in contact with each other, thereby achieving electrical connection.

[0034] As can be seen, the charging dock 100 has a highly compatible structural design, allowing both the left ear receiver 210 and the right ear receiver 220 to be charged independently on the charging dock 100, thus improving charging efficiency. Secondly, users only need to place the left ear receiver 210 or the right ear receiver 220 on the charging contact surface 11 to automatically complete magnetic positioning and charging connection, making operation simple and easy to use, thus enhancing the user experience. Specifically, both the left ear receiver 210 and the right ear receiver 220 can utilize the attraction between the first magnetic contact and the second magnetic contact 20 to achieve rapid and accurate positioning between the receiver and the charging dock 100, ensuring stable contact between the first charging contact 230 and the second charging contact 30, avoiding charging failure due to poor contact, and improving charging reliability.

[0035] Furthermore, the charging dock 100 is also compatible with various binaural receivers 200 that employ magnetic contact charging designs, and is not limited to those described above. Figure 1 The structure of the binaural receiver 200 and the charging dock 100 shown can be adapted to the structure of the binaural receiver 200 to improve its versatility.

[0036] Furthermore, such as Figure 2CAs shown, the charging contact surface 11 has two perpendicular first virtual center lines 111 and second virtual center lines 112. The second magnetic contact 20 and the second charging contact 30 are both located on the first virtual center line 111, or the second magnetic contact 20 and the second charging contact 30 are both located on the second virtual center line 112.

[0037] Preferably, the second magnetic contact 20 and the second charging contact 30 are both located on the first virtual center line 111, and the two second charging contacts 30 are located between the two second magnetic contacts 20. When the left ear receiver 210 and the right ear receiver 220 are placed on the charging contact surface 11, the first magnetic contact and the second magnetic contact 20 automatically complete magnetic positioning, while ensuring that the first charging contact 230 and the second charging contact 30 also complete positioning and electrical connection.

[0038] Furthermore, such as Figure 2D As shown, the base body 10 has a recessed charging compartment 12 on its surface. The shape of the charging compartment 12 is adapted to the shape of the left ear receiver 210 and the right ear receiver 220, so that the left ear receiver 210 or the right ear receiver 220 can be positioned in the charging compartment 12 and will not easily fall off the charging compartment 12; at the same time, the concave surface of the charging compartment 12 serves as the charging contact surface 11.

[0039] Furthermore, to accommodate the sound-emitting portions 240 on the left ear receiver 210 and the right ear receiver 220, the charging contact surface 11 also has two symmetrically arranged and further recessed adapter portions 113. One adapter portion 113 is adapted to the sound-emitting portion 240 of the left ear receiver 210, and the other adapter portion 113 is adapted to the sound-emitting portion 240 of the right ear receiver 220, so that the sound-emitting portion 240 can be accommodated in the adapter portion 113. In some embodiments, the adapter portion 113 is a groove structure; in other embodiments, the adapter portion 113 is a recessed hole structure.

[0040] like Figure 2E As shown, the charging base 100 also includes a charging circuit board 40 disposed inside the base body 10, and the second charging contact 30 is electrically connected to the charging circuit board 40 to realize current transmission.

[0041] Preferably, both the second charging contact 30 and the second magnetic contact 20 are columnar structures, fixed on the charging circuit board 40, and exposed on the charging contact surface 11. In other embodiments, both the second charging contact 30 and the second magnetic contact 20 are fixedly disposed on the charging contact surface 11, and the charging circuit board 40 is electrically connected to the second charging contact 30 via a conductive cable. In other embodiments, the second charging contact 30 is fixed to the charging circuit board 40 by welding; or, the second charging contact 30 is electrically connected to the charging circuit board 40 via a conductive spring sheet; or, the second charging contact 30 is fixed to the charging circuit board 40 by conductive adhesive or conductive glue; or, the second charging contact 30 is integrated on the printed circuit of the charging circuit board 40, that is, the second charging contact 30 and the conductive track of the charging circuit board 40 are integrally formed.

[0042] Meanwhile, to facilitate production and assembly of the base body 10, the base body 10 is designed to include a front shell 13 and a rear shell 14. Preferably, the front shell 13 and the rear shell 14 are detachably connected, for example, by snap-fit ​​connections or threaded connections. Figure 2E As shown, the charging compartment 12 is preferably disposed on the front shell 13.

[0043] In this embodiment, in order to ensure that the charging base 100 can also disinfect the left ear receiver 210 or the right ear receiver 220, the base body 10 also includes a sterilizer (not shown) disposed in the base body 10, and the sterilizer is electrically connected to the charging circuit board 40.

[0044] Preferably, in some embodiments, the sterilizer is an ultraviolet (UV) sterilization lamp, and at least the front shell 13 is made of a transparent material, such as polycarbonate (PC), acrylic, ABS, or a mixture of these transparent materials. This allows the UV light from the sterilization lamp to pass through the front shell 13, achieving sterilization of the left ear receiver 210 or the right ear receiver 220. Furthermore, when the adapter portion 113 on the charging contact surface 11 has a recessed structure, the UV light directly contacts the sound-emitting portion 240 of the left ear receiver 210 or the right ear receiver 220, resulting in better sterilization. In other embodiments, the sterilizer is an ozone generator capable of producing ozone, which is then used to sterilize the left ear receiver 210 or the right ear receiver 220.

[0045] like Figure 2E As shown, in this embodiment, the base body 10 also includes a charging interface 16 disposed on the base body 10. The charging interface 16 is electrically connected to the charging circuit board 40. An external power source can be connected through the charging interface 16 to supply power to the charging circuit board 40.

[0046] Preferably, to provide a more intuitive, safer, and smarter charging experience, the charging dock 100 is also equipped with a first display screen (not shown). The first display screen is preferably located on the front shell 13 and electrically connected to the charging circuit board 40. The first display screen can display information such as the voltage, current, and power of the charging dock 100 during charging, allowing users to understand the charging progress and device status. It can also monitor parameters such as charging temperature and the health status of the battery inside the left ear receiver 210 or right ear receiver 220 in real time, and promptly alarm in case of abnormalities, effectively ensuring charging safety. The left ear receiver 210 or right ear receiver 220 can also display information such as charging time, remaining power, and charging mode, making it convenient for users to operate and select.

[0047] Furthermore, such as Figure 2F As shown, in order to facilitate fixing the charging base 100, the rear shell 14 has a mounting part 15 on the side opposite to the front shell 13. The mounting part 15 can be a slot, a clip or other structure, so as to facilitate fixing.

[0048] Preferably, the mounting part 15 is a slot, and the mounting part 15 also includes a back plate 17 located in the slot. The back plate 17 has a first engaging part 18, which can be a protruding card block or a recessed card hole, card groove or other structure.

[0049] Furthermore, such as Figures 3A to 3C As shown, this utility model also provides a charging box 300, which includes a box body 320 and a box cover 310. The box body 320 is provided with a charging panel 311, a controller, a connector 312 and the aforementioned charging base 100. The controller is electrically connected to the charging base 100, and the charging base 100 is fixed to the charging panel 311 through the connector 312. The box cover 310 can cover the box body 320 to protect the box body 320.

[0050] like Figure 3B and Figure 3C As shown, the charging panel 311 has multiple connectors 312, each of which can be fitted with a charging base 100. In this embodiment, the connector 312 has an L-shaped plate structure and includes a first connecting part 3121 and a second connecting part 3122. The first connecting part 3121 has a second engaging part 3123 that is adapted to the first engaging part 18, so that the first connecting part 3121 can be inserted into the mounting part 15 of the rear shell 14 and fixed by the first engaging part 18 and the second engaging part 3123. Preferably, one of the first engaging part 18 and the second engaging part 3123 is a locking block and the other is a locking hole, so that they can be engaged and fixed.

[0051] The second connecting portion 3122 of the connector 312 is provided with a fixing portion 3124, which may be a fixing hole or other structure, so that the second connecting portion 3122 can be detachably fixed to the charging panel 311. In some other embodiments, the connector 312 may also have other structural forms; in some other embodiments, the connector 312 may also be designed to be integrally formed with the charging panel 311.

[0052] Furthermore, the charging panel 311 also has multiple cable passage holes 313, which are located near the connector 312. These cable passage holes 313 allow connecting cables to pass through, connecting the charging base 100 and the controller inside the housing 320, thereby enabling the controller to supply power to the charging base 100. Preferably, the end of the connecting cable is pluggable to the charging interface 16 of the charging base 100, facilitating maintenance and replacement when the charging base 100 is damaged.

[0053] Furthermore, the charging panel 311 has multiple second displays, which are located adjacent to the cable hole 313. The second displays have the same function as the first displays and can display the charging information of the charging base 100.

[0054] In summary, the charging case 300 in this embodiment can charge both multiple left ear receivers 210 and multiple right ear receivers 220, demonstrating good compatibility.

[0055] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0056] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.
