Drum with sound duration and sound intensity adjusting function

Abstract

The invention discloses a drum with a sound duration and sound intensity adjusting function. The drum mainly comprises a drum wall, a limiting strip, a fixing bolt, an electromagnet support, a compensation surface support, a compensation surface, a drum surface, an electromagnet and a sound sensor. The electromagnet and the compensation surface are respectively installed on respective supports, the support is installed on the limiting strip on the inner side of the drum wall through the fixing bolt, the support can move up and down along the limiting strip, and the distances between the compensation surface and the drum surface and between the compensation surface and the electromagnet are adjusted. The sound sensor can receive sound signals of the drum surface during drum beating, convertthe sound signals into electric signals and transmit the electric signals to a computer. The computer processes the corresponding electric signal according to the signal and transmits the electric signal to a control coil of the electromagnet; the electromagnet drives the compensation surface to vibrate at a specific frequency and amplitude, and the vibration of the compensation surface can drivethe air between the compensation surface and the drum surface to vibrate, thereby further driving the drum surface to vibrate continuously, and achieving the adjustment of the sound length and soundintensity of sound generated by the vibration of the drum surface.

Description

technical field [0001] The invention relates to the field of percussion instruments, in particular to a drum with the function of adjusting sound length and sound intensity. Background technique [0002] The drum kit is a popular musical instrument that developed simultaneously with rock music from the 1950s to the 1960s.
