Abstract:
1. A percussion-instrument pickup, comprising: a resonance plate that is made of a metal containing at least copper and has an area smaller than the area of a hitting surface of a percussion instrument to which the percussion-instrument pickup is attached; a weight part attached to a part of the perimeter of the resonance plate, said weight part having a volume of material separate from said resonance plate; an attachment part disposed at a predetermined distance from the point of attachment of the weight part; and a plurality of vibration pickups attached to the surface of said resonance plate between said attachment part and said weight part; wherein: said attachment part is configured to be attached to an inner wall of a body supporting said hitting surface of said percussion instrument, said resonance plate is configured to be attached to said inner wall of said body via said attachment part in a cantilever configuration, to be disposed inside said hitting surface, to be excited by a vibration of said body, said weight part is configured to be disposed inside said hitting surface and spaced apart therefrom when said resonance plate is attached to said inner wall of said body via said attachment part in the cantilever configuration, said vibration pickups are configured to be disposed inside said hitting surface and spaced apart therefrom when said resonance plate is attached to said inner wall of said body via said attachment part in the cantilever configuration, to produce sound signals from resonance of said resonance plate, a resonance frequency of said resonance plate depends on a weight of said weight part.
