The original drum-set cymbals are all made of metal material, and with the development of electronic cymbals which are mainly made of some non-metallic materials or partially wrapped by some metallic materials, in order to be able to exhibit more timbre effects on the same cymbal, electronic cymbals have slowly started to appear. However, the striking feel of an electronic cymbal cannot be achieved, and so there have been designed products such as case 1 (publication No. CN105206254B) and case 2 (publication No. CN207818182U) in which a single part is mounted or integrated. However, the existing products have the phenomenon that a signal cannot be triggered when a drumstick lightly strikes the cymbal or a lingering sound (namely, the lingering sound is recognized as a plurality of sounds when the drumstick strongly strikes the cymbal), and the phenomenon that the lingering sound is not responded to when the drumstick is tapped or the cymbal is heavily tapped is unreasonable in application of the products. Meanwhile, the existing product can change the original tone effect of the product to a great extent. Case 2 the product is made into a whole and cannot achieve universality.

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, for the utility model discloses a silence wiping piece electric signal recognition device 10, include: a base 11 and a rear cover 12. The rear cover 12 is detachably fixed to the base 11 by bolts and nuts and forms a mounting cavity 13 together with the base 11. The mounting cavity 13 is internally provided with a damping device 14, a piezoelectric ceramic piece 15 and an electric signal processing circuit board 16. The damper 14 is fixed to the base 11. The piezoelectric ceramic plate 15 is fixed on one end of the shock absorber 14 far away from the base 11 and is electrically connected to the electric signal processing circuit board 16 through a lead. The electric signal processing board is fixed into the mounting cavity 13. The mute wiping sheet electric signal identification device 10 is also provided with a signal output device 17. The signal output device 17 is fixed to the outside of the rear cover 12 and electrically connected to the signal processing circuit board.
Specifically, the whole mute cymbal electric signal recognition device combined by the structure is fixed on the mute cymbal, abuts against the edge of the mute cymbal and is arranged below the mute cymbal. The device has light and simple structure, simple installation process and easy installation. The damping device 14 is used for filtering interference vibration waves generated in the knocking process of the mute cymbals, so that the final electric signal identification effect is more accurate. The piezoelectric ceramic piece 15 is used for collecting the striking signal of the mute cymbal and transmitting the signal to the electric signal processing circuit board 16 in the form of voltage for processing. The electric signal processing circuit board 16 is used for performing algorithm processing on the acquired electric signals, analyzing the electric signals to obtain effective striking signals and force values, and transmitting the striking signals and the force values obtained through analysis to the terminal through the signal output device 17 in a standard midi format.
