ABSTRACT:
A foldable electronic bass drum includes a base to be placed on a floor surface with a coupling device provided at a portion of the base for coupling a foot pedal with a beater. On a portion of the base remote from the coupling device, an arm mounting a pad to be struck by the beater at one end of the arm and an arm supporting device for pivotally supporting the other end of the arm are provided. The other end of the arm is fixed to the base by a fixing device so that the beater of the foot pedal can strike the pad. A vibration of the pad is picked up by a pick up device for converting a vibration of the pad into an electrical signal. When the foldable electronic bass drum is not used, the arm is released from the fixing device so that the arm is moved forward the foot pedal and laid on the base thereby establishing conveyance.
