[0002] Wireless microphones have become common equipment in fields such as stage performances and conference recordings. Their main components include a transmitter and a receiver, which transmit audio signals wirelessly. Current wireless microphone transmitters typically have built-in batteries, allowing them to be free from the constraints of wires.

[0003] Current wireless microphone transmitters primarily use wired charging or charging cases for charging. While wired charging provides a stable current, it limits the transmitter's portability and range of use. Charging cases are convenient, but the transmitter needs to be turned off to charge, preventing simultaneous charging and use. Regardless of the charging method, a dedicated charging process is required after the transmitter's battery is depleted, significantly impacting its battery life and portability, thus failing to meet users' growing needs.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] Example 1:

[0026] Reference Figure 1-3A charging structure includes a charging cable 3, a transmitter body 1, and a charging base 2. The transmitter body 1 has a built-in first power supply 13 and a charging terminal 12 electrically connected to the first power supply 13. The charging base 22 has a built-in PCB motherboard 25 and an input terminal 26, an output terminal 23, and a second power supply 24 electrically connected to the PCB motherboard 25. The charging base 2 has a receiving groove 21 for accommodating part of the transmitter body 1. One end of the charging terminal 12 extends outside the transmitter body 1. The charging terminal 12 and the output terminal 23 are paired vertically to form a conductive connection. The input terminal 26 can be detachably connected to the charging cable 3. The charging cable 3 can be connected to an external power source and charged through the PCB motherboard 25 to the second power supply 24 or the first power supply 13. The structure is designed to be pluggable. The charging dock 2, which is connected to the charging cable 3 and has a built-in rechargeable power supply, allows the second power supply 24 inside the charging dock 2 to be charged via an external power source connected to the charging cable 3 when the charging dock 2 is not charging. Furthermore, the charging dock 2 can supply power to the transmitter detached from the charging cable 3, enabling simultaneous charging and use of the transmitter. Additionally, when the other end of the charging cable 3 is connected to a power bank (not shown in the figure), the transmitter can be used while the charging dock 2 is connected to the charging cable 3. In this case, the power bank simultaneously supplies power to both the charging cable 3 and the transmitter. Based on usage priority, in this embodiment, when the transmitter is not in operation and is plugged into the charging dock, the external cable prioritizes charging the transmitter, thereby improving the transmitter's battery life and portability. In this embodiment, the receiving slot 21 is located on the top of the charging dock 2.

[0027] The output terminal 23 is a female pogo pin, and the charging terminal 12 is a male pogo pin that is compatible with the female pogo pin. The transmitter body 1 and the charging base 2 are electrically connected through the pogo pin structure, which helps to improve the insertion efficiency between the transmitter and the charging base 2. The input terminal 26 and the charging cable 3 can use compatible interfaces, such as Type-C, MicroUSB, etc., which are not limited here.

[0028] Reference Figure 2 and Figure 3As shown, it also includes a magnetic attraction structure, which includes a first magnetic element 14 and a second magnetic element 22. The first magnetic element 14 and the second magnetic element are opposite in magnetism. The first magnetic element 14 and the second magnetic element 22 are respectively disposed in the transmitter body 1 and the charging base 2, and are arranged opposite to each other to achieve a magnetic connection between the transmitter body 1 and the charging base 2. There are two first magnetic elements 14 symmetrically distributed in the transmitter body 1 with the charging terminal 12 as the central axis, and there are two second magnetic elements 22 symmetrically distributed in the charging base 2 with the output terminal 23 as the central axis. By designing magnetic elements with opposite magnetism in the transmitter body 1 and the charging base 2, the combination strength between the transmitter body 1 and the charging base 2 can be improved when they are combined. The first magnetic element 14 and the second magnetic element 22 are preferably square structures, but in other embodiments they can also be disc-shaped or other shapes, which are not limited here.

[0029] Reference Figure 2 and Figure 3 As shown, the transmitter body 1 is provided with a microphone core 11. The transmitter body 1 also has a second PCB board 15 that is electrically connected to the microphone core 11 and the first power supply 13. The transmitter body 1 extends to the outside of the receiving slot 21 at the end near the microphone core 11. The above design can meet the charging of the transmitter without affecting the use of the transmitter itself.

[0030] Reference Figure 3 As shown, in Embodiment 1, the receiving groove 21 is provided on the top of the charging base 2. Both the transmitter body 1 and the side wall of the charging base 2 are provided with clamping members 4. The clamping members 4 on the transmitter body 1 are at least partially received in the receiving groove 21. The clamping members 4 can be collar clips or magnetic clips. The transmitter can be fixed to clothing by collar clips or magnetic clips, which is convenient for users to use.

[0031] This utility model embodiment also provides a wireless microphone, including a receiver (not shown) and a charging structure as described above.

[0032] Example 2:

[0033] Reference Figure 4 The difference between Embodiment 2 and Embodiment 1 is that the receiving groove 21 is provided on the side wall of the charging base 2, and the clamping member 4 is provided on the side wall of the transmitter body 1. The clamping member 4 extends outside the receiving groove 21 and is completely exposed outside the charging base 2. The charging base 2 does not need to be designed with a separate collar clip structure. The clamping member 4 on the transmitter can be used as the collar clip structure of the charging base 2 and the transmitter as a whole. When in use, the user will install the transmitter and the charging base 2 as a whole on the collar through the collar clip structure to achieve charging and use at the same time, which can save the overall manufacturing cost.

[0034] The magnetic directions of the first magnetic component 14 and the second magnetic component 22 are designed to be either intersecting or perpendicular to the clamping direction of the transmitter body 1. This intersecting or perpendicular arrangement of the magnetic attraction structure with the direction of gravity helps to prevent the charging base 2 from becoming detached from the transmitter.

[0035] Example 3:

[0036] Reference Figure 5-6 The difference between Embodiment 3 and Embodiment 2 is that the top of the charging base 2 is provided with a baffle 27 that abuts against the transmitter body 1 at the edge of the receiving groove 21. The middle of the baffle 27 is provided with a clearance groove for preventing the microphone core 11 from being detached. The designed baffle structure helps to further prevent the transmitter body 1 from being detached from the charging base 2. At the same time, the clearance groove can prevent the microphone core 11 from being interfered with, ensuring the normal use of the charging and use function.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
