Abstract
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.
Claims20
An electronic musical instrument adapted to permit changes in timbre, comprising:
- signal source means including at least one natural mechanical vibratory means which vibrates to produce a plurality of frequency components over a wide frequency band when a shock is applied to said vibratory means by a person using the musical instrument, and at least one vibration sensor means which detects the vibration of said vibratory means and converts said frequency components into an electric shock signal having characteristics dependent upon the nature of the shock applied to said vibratory means by the person using the musical instrument;
- and
- resonance circuit means which is supplied with said electric shock signal from said signal source means and resonates with selected ones of the frequency components in said electric shock signal to generate a resonance signal;
- said resonance signal from said resonance circuit means being output as a sound signal of said electronic musical instrument.
