Description

Adjustable drum box

Technical Field

The utility model relates to a relevant device in shelf drum field specifically is a drum case with adjustable.

Background

Drum kits, i.e., jazz drums, are an important percussion instrument in jazz teams and generally consist of a foot-operated bass drum (also known as a "tom"), a snare drum, two or more tom-tom drums, one or two cymbals, a rhythm cymbal, and a pedal cymbal. Of course, some bells, wooden fish, sandhammers, triangular irons and tone trees are added for playing, and a person plays the music regardless of the number of the added devices. The drummer strikes each component with a drumstick to make it sound. The drumsticks commonly used in jazz music include a wooden drumstick, a drum brush made of a steel wire, a bundle stick made of a bundle of thin wooden strips, and the like. The top of the strike face is called the strike membrane; the bottom consists of a snare (a string made of a string of sheep intestine, nylon or steel wire) stretched on the surface of the skin, which is called a snare surface. When the drumhead is knocked, the strings on the snare surface resonate to generate a lattice sound.

However, the tone quality of the drum cannot be adjusted by the existing drum box, and the knocking membrane cannot be replaced by simple operation, so that the drum box which can change the tone quality by adjusting the empty volume of the drum box body needs to be designed.
