[0038] The present application discloses a flicking piece structure and a musical instrument.

[0039] Please refer to Figures 1 to 3In an embodiment of the present application, a plectrum structure comprises a musical instrument shell 100, a plectrum device 200, a detection device 300, a reset device 400, and a limiting device 500. The plectrum device 200 is installed between the musical instrument shell 100 and the detection device 300 and rotatably connected with the musical instrument shell 100. The detection device 300 comprises a circuit board 301 fixedly installed on the musical instrument shell 100, a sensor 302 fixedly installed on the circuit board 301, and a detection shaft 303 movably connected with the sensor 302 and drivingly connected with the plectrum device 200. The reset device 400 is elastically connected with the plectrum device 200 and used for restoring the initial position of the plectrum device 200. The limiting device 500 is arranged between the musical instrument shell 100 and the plectrum device 200 and used for limiting the rotation range of the plectrum device 200.

[0040] In the working process, the plectrum device 200 is installed between the musical instrument shell 100 and the detection device 300, avoiding the installation of the plectrum device 200 on the circuit board 301.

The auxiliary limiting plate 705 is not only beneficial to increase the connection strength between the first cylinder 702 and the musical instrument shell 100, but also can form an auxiliary limiting effect in the working process through the design of the first sector slot 706, so as to share the impact force of the limiting device 500 in the working process, and is beneficial to ensure the stability and reliability of the limiting device 500.

[0047] Please refer to Figure 7 In another embodiment of the present application, the mounting portion 700 is provided as a second cylinder 703, a second cylindrical hole 704 is arranged on the musical instrument shell 100 corresponding to the second cylinder 703, and the second cylinder 703 is inserted into the second cylindrical hole 704.

In the working process, the rotating shaft 201 can be axially limited, so as to increase the stability of the rotating shaft 201 in the axial direction. Moreover, an auxiliary limiting effect can be formed in the working process, so as to share the impact force of the limiting device 500 in the working process, and is beneficial to ensure the stability and reliability of the limiting device 500.

[0048] Please refer to Figures 1 to 10 In an embodiment of the present application, the reset device 400 includes a connecting sleeve 401, one end of the connecting sleeve 401 is detachably connected with the detection shaft 303, the other end of the connecting sleeve 401 away from the detection shaft 303 is provided with a driven portion 800 corresponding to the driving portion 600, the driving portion 600 and the driven portion 800 are detachably connected, the connecting sleeve 401 is fixedly connected with an elastic member 402, and the other end of the elastic member 402 is elastically connected to the musical instrument shell 100.

[0049] In the working process, the torque generated by the driving portion 600 can be indirectly transmitted to the detection shaft 303 and the elastic member 402 through the connecting sleeve 401, so as to avoid that the driving portion 600 directly drives the detection shaft 303, which is beneficial to the mutual disassembly during maintenance, and can also conveniently store energy for the elastic member 402. After the user releases the pick 202, the elastic member 402 reversely drives the connecting sleeve 401, the rotating shaft 201 and the detection shaft 303 to return to the initial position.

[0050] Please refer to Figures 1 to 10 In an embodiment of the present application, the elastic member 402 is configured as a torsion spring 4021, the middle part of the torsion spring 4021 is a spiral part 40211, the two ends of the torsion spring 4021 are straight rod parts 40212, the two ends of the straight rod parts 40212 are symmetrically abutted on the musical instrument shell 100, the spiral part 40211 is sleeved on the connecting sleeve 401, and the middle part of the spiral part 40211 is fixedly connected to the connecting sleeve 401 in a strong adhesive manner. Thus, no matter which direction the connecting sleeve 401 rotates, the corresponding part of the spiral part 40211 is driven to rotate, so that the torsion spring 4021 completes energy storage. When the user releases the plectrum 202, the torsion spring 4021 reversely drives the connecting sleeve 401, the rotating shaft 201 and the detection shaft 303 to return to the initial position.

[0051] It can be understood that in other embodiments of the present application, the elastic member 402 can also be configured as two symmetrically arranged tension springs. As long as the two ends of the tension springs are fixedly connected to the musical instrument shell 100 and the connecting sleeve 401 respectively, the elastic member 402 can be energized when the connecting sleeve 401 rotates, so as to drive the connecting sleeve 401, the rotating shaft 201 and the detection shaft 303 to return to the initial position.

[0055] It can be understood that in other embodiments of the present application, the card slot 601 can be opened at the end of the connecting sleeve 401, and the clamping block 801 is correspondingly arranged at the end of the rotating shaft 201.

[0056] Please refer to Figures 1 to 10 In a specific embodiment of the present application, the limiting device 500 includes a first limiting part 501 fixedly arranged on the musical instrument shell 100, and a second limiting part 502 fixedly arranged on the connecting sleeve 401 in symmetry.

The buffer pad 503 is made of a flexible material with certain elasticity, such as rubber, silicone, etc. In the working process, by adopting the buffer pad 503, the second limiting part 502 can avoid directly impacting on the first limiting part 501, thereby reducing the impact force of the second limiting part 502 on the first limiting part 501. On the one hand, it can improve the service life of the second limiting part 502 and the first limiting part 501, and on the other hand, it is beneficial to avoid noise caused by impact, thereby ensuring the playing effect of the musical instrument.
