Electronic musical instrument

摘要

The vibration of a vibratory element, caused by applying thereto a shock, is detected by a vibration sensor and provided as an electric shock signal to a resonance circuit. The resonance frequencies and resonance decay time of the resonance circuit can freely be adjusted. By setting the resonance frequencies and resonance decay time of the resonance circuit to arbitrary values, desired frequency components are extracted from the electric shock signal and output as a sound signal of an electronic musical instrument.
