Three-in-one drum

摘要

A three-in-one drum includes a drum chamber, a drum skin and pressing rings. A beating tray is vertically and adjustably disposed in the drum chamber and covered with a cushion. The bottom of the beating tray has a microphone vibrator connected to a loudspeaker box. When the adjusting rod is rotated clockwise, the beating tray rises and the cushion is close to the drum skin. The drum skin does not ground when being beaten, this is the mute drum function. An beating trigger connected with an electronic sound source sends electronic signal to perform the electric drum function. The microphone vibrator amplifies the audio frequency signal to perform the audio amplification function. When the adjusting rod is rotated counter clockwise, the beating tray is lowered and the cushion is located away from the drum skin which sounds when being beaten to perform the raw sound drum function.
