[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] It should also be understood that the terms used in this specification of the utility model are merely for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this specification of the utility model and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0031] It should be further understood that the term "and / or" used in this specification of the utility model and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] Please refer to Figures 1 to 2 , a specific embodiment of the utility model discloses a erhu clip 2, which includes a first clamping arm 21 and a second clamping arm 22. The first clamping arm 21 and the second clamping arm 22 are rotatably connected. The first clamping arm 21 is inserted into the sound hole 111 of the erhu, and the second clamping arm 22 abuts against the erhu.

[0033] Specifically, through the rotational connection design of the first clamping arm 21 and the second clamping arm 22, the erhu clip 2 can be easily clamped on the erhu without the need for additional screws, straps or other fixing devices. This design not only simplifies the installation process, but also makes the erhu clip 2 more convenient to carry and does not occupy too much space.

[0034] As Figure 2 shown, it further includes a rotating rod 23. Connecting parts 211 are provided in the middle of both the first clamping arm 21 and the second clamping arm 22. The rotating rod 23 is disposed through the connecting parts 211. A spring 24 is sleeved on the rotating rod 23. The two ends of the spring 24 are respectively fixedly connected to one end of the first clamping arm 21 and one end of the second clamping arm 22.

[0035] Specifically, through the clamping force provided by the spring 24 and the abutting action of the second clamping arm 22, the erhu clip 2 can be firmly fixed on the erhu barrel 1, avoiding loosening or falling off during the performance.

[0036] As Figures 1 - 2 shown, one end of the first clamping arm 21 is an insertion end 212, and the shape of the insertion end 212 is adapted to the shape of the sound hole 111.

[0037] Specifically, in this embodiment, in order to ensure that the first clamping arm 21 can be firmly and precisely inserted into the sound hole 111 of the erhu, the design of the insertion end 212 is crucial. The shape of the insertion end 212 must be highly adapted to the shape of the sound hole 111 to achieve a tight insertion effect. The shape of the insertion end 212 is precisely designed according to the specific shape of the sound hole 111. Generally, the sound hole 111 is usually circular, oval, or other regular or irregular shapes, and the insertion end 212 is correspondingly designed to match the shape of the sound hole 111 to ensure seamless docking during insertion and reduce gaps and looseness. In addition to shape adaptation, the size of the insertion end 212 also needs to match the size of the sound hole 111. The diameter of the insertion end 212 should be slightly smaller than the inner diameter of the sound hole 111 to facilitate easy insertion and maintain a certain degree of tightness. At the same time, the length of the insertion end 212 also needs to be appropriate to ensure stable fixation within the sound hole 111 after insertion.

[0038] As Figure 2 shown, one end of the second clamping arm 22 is a clamping end 221, and the clamping end 221 is arc-shaped.

[0039] Specifically, the clamping end 221 of the second clamping arm 22 is designed to be arc-shaped, and the curvature of the arc is precisely calculated to maximize the contact area and reduce gaps. This design fully considers the contact area and fit with the erhu sound box 1. The arc-shaped clamping end 221 can better adapt to the curved surface shape of the erhu sound box 1, thereby increasing the contact area and improving the stability of clamping.

[0040] As Figures 1 - 2 shown, a protective sleeve 25 is sleeved on the insertion end 212 and the clamping end 221, and the protective sleeve 25 is made of shock-absorbing or sound-insulating material.

[0041] Specifically, in this embodiment, in order to protect the erhu sound box 1 from possible damage caused by the insertion end 212 and the clamping end 221, and to reduce sound leakage and interference during sound transmission, a protective sleeve 25 is specifically sleeved on the insertion end 212 and the clamping end 221. The material of the protective sleeve 25 has good shock-absorbing performance and sound-insulating effect. Common shock-absorbing materials include rubber, silicone, foam, etc., which can effectively absorb and disperse impact forces to protect the erhu sound box 1 from damage; sound-insulating materials can be selected such as sponge, sound-insulating cotton, etc., which can reduce sound leakage and reflection during sound transmission and improve the sound pickup effect.

[0042] Please refer to Figures 3 to 6, a specific embodiment of the present utility model also discloses a wireless pickup erhu, which includes an erhu body, a pickup 3, and the erhu clip 2 in the above embodiment. The erhu body includes an erhu sound box 1. One side wall of the erhu sound box 1 is provided with a sound outlet window 11, and the sound outlet window 11 is provided with a plurality of sound outlet holes 111. The erhu clip 2 is inserted into the sound outlet holes 111, and the pickup 3 is located on one side of the sound outlet window 11 and is clamped to the erhu clip 2.

[0043] Specifically, the erhu sound box 1, as the main part of the erhu, the sound outlet window 11 on its side wall is not a traditional closed structure, but is composed of a plurality of evenly distributed sound outlet holes 111. These sound outlet holes 111 not only facilitate the natural dissipation of sound, but also provide an interface for the installation of the erhu clip 2. Insert the erhu clip 2 into the sound outlet holes 111 of the erhu sound box 1 to ensure that the clip is stable and does not shake. Subsequently, clamp the pickup 3 to the erhu clip 2. After the installation is completed, the wireless transmission function of the pickup 3 can be turned on and paired with the receiving device. The entire installation process is simple and fast, without any modification or damage to the erhu.

[0044] In this embodiment, the pickup 3 is directly installed near the sound outlet window 11 of the erhu, which can minimize the loss and interference of sound during transmission. Using the wireless transmission method can also avoid the constraints and inconveniences brought by the traditional wired connection method, enabling the performer to move and perform freely. Moreover, the installation and disassembly of the erhu clip 2 and the pickup 3 are very simple and fast, and can be completed without professional skills or tools.

[0045] As Figure 6 shown, the pickup 3 includes a pickup housing 31, a wireless transmitter 32, a power supply 33, a PCB board 34, and a microphone 35. The wireless transmitter 32, the power supply 33, the PCB board 34, and the microphone 35 are all arranged inside the pickup housing 31. A switch button is also provided on the pickup housing 31. The wireless transmitter 32, the power supply 33, and the microphone 35 are respectively connected to the PCB board 34. A clamping board 36 is provided above the power supply 33, and the clamping board 36 is fixed to the inside of the pickup housing 31 by screws 37.

[0046] Specifically, the switch button provided on the pickup housing 31 enables the user to easily control the on / off state of the pickup 3. The built-in wireless transmitter 32 enables the pickup 3 to wirelessly transmit audio signals, getting rid of the constraints of the traditional wired pickup 3. And by integrating key components such as the wireless transmitter 32, the power supply 33, the PCB board 34, and the microphone 35 inside the pickup housing 31, a high degree of integration of the pickup 3 is achieved. This design not only reduces the volume and weight of the pickup 3, improves its portability, but also makes the installation and use more convenient and fast.

[0047] As Figures 4 - 5As shown, the other end of the first clamping arm 21 is a fixing part 213. The pickup 3 is provided with a mounting hole 38, and the fixing part 213 is inserted into the mounting hole 38 so that the pickup 3 is fixedly installed on the erhu clip 2.

[0048] Specifically, through the cooperation between the fixing part 213 on the first clamping arm 21 and the mounting hole 38 on the pickup 3, the pickup 3 can be firmly installed on the fixing part 213 of the clamping arm, thereby realizing stable and reliable audio pickup and transmission.

[0049] As Figure 4 and Figure 6 shown, the fixing part 213 is provided with a clamping hole 2131, and a protrusion 361 is provided in the middle of the clamping plate 36. The protrusion 361 is clamped with the clamping hole 2131 to form a stable snap structure.

[0050] Specifically, when the fixing part 213 moves along a preset track (i.e., the mounting hole 38) towards the clamping plate 36, the clamping hole 2131 on the fixing part 213 gradually approaches the protrusion 361 on the clamping plate 36. When the clamping hole 2131 is precisely aligned and encloses and locks the protrusion 361, an interference fit will occur between the two, that is, the locked state. At this time, due to the combined action of the geometric limitation of the structural design and the elastic restoring force of the material, the fixing part 213 and the clamping plate 36 are firmly clamped together to achieve stable locking. In order to separate the fixing part 213 from the clamping plate 36, the fixing part 213 needs to be moved in the opposite direction to the locking direction. During this process, due to the elasticity of the material of the protrusion 361 and the external force, the fixing part 213 is no longer restricted by the locking force, and the fixing part 213 can freely return to its initial position, thereby realizing unlocking and separation.

[0051] As Figure 3 shown, the sound outlet window 11 is a hexagonal mesh structure, and the erhu clip 2 can be inserted into the sound outlet holes 111 on each side of the sound outlet window 11 to change the position of the pickup 3.

[0052] Specifically, the hexagonal mesh structure of the sound outlet window 11 provides multiple sound outlet holes 111, enabling the erhu clip 2 to be inserted at different positions according to needs. This design allows the performer to flexibly adjust the position of the pickup 3 according to the performance environment, tone requirements or personal preferences to achieve the best pickup effect. By adjusting the position of the pickup 3, the distance and angle between the pickup 3 and the sound source of the erhu can be optimized, so as to more accurately capture the tone and volume of the erhu and improve the sound quality of recording or live performance.

[0053] In this embodiment, both the erhu sound box 1 and the erhu clip 2 are detachably connected to the pickup 3 and the erhu clip 2.

[0054] Specifically, since the erhu sound box 1, the erhu clip 2 and the pickup 3 are detachably connected to each other, when a certain component is damaged or needs to be repaired, it can be individually disassembled and replaced without scrapping the entire device, greatly reducing the maintenance cost of the device; and the detachable design makes it simple and fast to replace components, and users can complete the replacement without professional tools or complex operations, improving the maintainability of the device.

[0055] As described above, the above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
