Sound Pick-up Device, Sound Instrument and Method for Picking-up Sound Vibrations

摘要

The sound pickup system (30) for the electric cello or guitar consists of piezoelectric membranes (14) with electrical connections (15). The strings (9) of the string instrument press on the upper portion of a bridge (5). The upper portion of the bridge is held on flexible side mountings (13) and a spring-loaded (4) central mounting with flexures on a baseplate (1). Pressure members (7) on arms (11) on the upper bridge bend the piezoelectric membrane to produce electrical signals.
