PROBLEM TO BE SOLVED: To provide a three-in-one drum having multiple functions.SOLUTION: Two inside slide units 9 are symmetrically arranged on an inner wall of a drum shell 1, and an adjustment lever 10 is rotatably attached between the inside slide units. Further, an adjustable percussion pad 4 is included so as to be adjusted upward and downward. A percussion flip-flop 6 is installed between the percussion pad and a cushion 5, and a microphone vibrator 7 is installed at the bottom of the percussion pad. When the adjustment lever is rotated in a normal direction, the percussion pad rises, and the cushion comes into contact with the drum head 2, so that a mute function is realized. When an external connection with an electronic sound source is established, the percussion flip-flop transmits an electronic signal, so that an electronic drum function is realized. When an external connection with a speaker is established, the microphone vibrator amplifies an audio signal to double, so that an audio amplification function is realized. When the adjustment lever is rotated in a reverse direction, the percussion pad is lowered, and the cushion moves away from the drum head. When the drum head is beaten, a sound occurs. That is, a raw sound drum function is realized.SELECTED DRAWING: Figure 2 |
