Electronic music drum - has inner surface of conical resonator chamber covered with sound absorbent material with output through microphone

摘要

The resonator chamber (2) has a microphone (4) set at a mid position. The flexible surface of the drum (17) is secured by a clamping ring (12) with screws (11) for fixing. Threaded nuts (14) are retained on the outer surface of the drum body. The internal surface of the resonator chamber is coated with a sound absorbing material (19) such that external transmission of vibration is kept to a min. Resonator openings (20) are formed in the tip of the cone. All sound output is via the amplifier and loudspeaker coupled to the microphone. ADVANTAGE - Limits sound output directly into room.
