[0002] The erhu's adjustable pickup, as an important auxiliary equipment for erhu performance, is a device that can help erhu musicians amplify the sound. It can convert the sound produced by erhu performance into electrical signals and amplify them through amplifiers to make the performance sound clearer and louder. At the same time, the adjustable pickup also allows musicians to adjust parameters such as volume and timbre as needed to meet different performance needs.

[0003] At present, the use of erhu pickups is usually to fix the pickups on the erhu, and the pickups are fixed to the sound box or sound post through pickup clips or patches.

After the outer wall of the connecting block 5 is fitted with the first clamping ring 601 and the second clamping ring 603, the angle between the first clamping ring 601 and the second clamping ring 603 is restored to its original size, so that the first clamping ring 601 and the second clamping ring 603 form an incomplete circular ring, the middle part of the connecting block 5 is clamped with the positioning column 605, the support spring 606 is restored to its original length, and the clamping assembly 6 is clamped and fixed to the wireless pickup 2.

[0040] like Figure 3 , Figure 5 and Figure 7 As shown, the adjustment component 8 includes a micro motor 801, the output end of the micro motor 801 is fixedly connected to an output shaft 802, the outer wall of the output shaft 802 is fixedly connected to a first bevel gear 803, both sides of the outer edge of the first bevel gear 803 are meshed with second bevel gears 804, the middle parts of the two second bevel gears 804 are fixedly connected to threaded rods 805, and the outer walls of the two threaded rods 805 are movably sleeved with bellows 806;

After the distance between the pickup clips 9 is larger than the width of the sound box, the wireless pickup 2 is attached to one side of the sound box, and then the micro motor 801 is rotated in the opposite direction, so that the two pickup clips 9 drive the clamping pads 10 to move toward each other and make the clamping pads 10 clamp the sound box of the erhu body 1, and the telescopic plate 12 is used to limit the pickup clip 9 and the mounting plate 607, and the sound box can be protected by the clamping pads 10 to prevent the pickup clip 9 from clamping the erhu body 1 for a long time, which leaves clamping marks on both sides of the sound box and damages the appearance of the erhu body 1.

[0045] The working principle and use process of the present invention:

[0046] First, the first magnetic block 302 is clamped into the first fixed plate 301, the second magnetic block 402 is clamped into the second fixed plate 401, and the second magnetic block 402 is brought close to the first magnetic block 302 so that the two are attracted and fixed. At this time, the clamping pin 304 is clamped into the second connecting plate 403, and the wireless pickup 2 drives the connecting block 5 to move through the first magnetic suction module 3 and the second magnetic suction module 4, and the connecting block 5 is clamped into the clamping assembly 6. At this time, the first clamp ring 601 and the second clamp ring 603 are opened to both sides with the hinge rod 602 as the center, and the angle between the first clamp ring 601 and the second clamp ring 603 becomes larger, and the two support springs 606 are compressed by the first clamp ring 601 and the second clamp ring 603 respectively;

[0047] After the outer wall of the connecting block 5 is fitted with the first snap ring 601 and the second snap ring 603, the middle part of the connecting block 5 is clamped with the positioning column 605, and the supporting spring 606 is restored to its original length. At this time, the clamping assembly 6 is clamped and fixed with the wireless pickup 2, and the micro motor 801 drives the output shaft 802 to rotate, and the output shaft 802 drives the first bevel gear 803 to rotate. The first bevel gear 803 is meshed with the two second bevel gears 804 at the same time and drives the two second bevel gears 804 to rotate, and the second bevel gear 804 drives the threaded rod 805 to rotate;

[0048] During the rotation of the threaded rod 805, the threaded rod 805 and the sound pickup clip 9 are threadedly rotated so that the sound pickup clip 9 moves to both sides along the rod wall of the threaded rod 805, and the sound pickup clip 9 drives the bellows 806 to move, and the bellows 806 extends outward, and the fixed spring 11 and the telescopic plate 12 are stretched and lengthened. At this time, the distance between the two sound pickup clips 9 increases. After the distance between the sound pickup clips 9 is larger than the sound box of the erhu body 1, the wireless sound pickup 2 is attached to one side of the sound box, and then the micro motor 801 is rotated in the opposite direction, so that the two sound pickup clips 9 drive the clamping pads 10 to move toward each other and clamp the sound box;

[0049] After the sound pickup clip 9 fixes the wireless sound pickup 2 and the erhu body 1, the Bluetooth device is connected to the wireless sound pickup 2 to pick up the sound of the erhu body 1, and the operation is completed.
