Electronic musical instrument employing finger-pressure means to sequentially energize oscillator means and amplifier means

Claim 1

A MUSICAL INSTRUMENT WHICH COMPRISES A TRANSISTORIZED TONE GENERATOR HAVING A FINGER-OPERATED TONE SELECTOR, MEANS FOR BIASING SAID TONE SELECTOR TO A NORMAL REST POSITION IN WHICH NO TONE IS SELECTED, A POWER SUPPLY FOR SAID TONE GENERATOR CONNECTED THERETO THROUGH A SWITCH OPERATED BY SAID TONE SELECTOR, SAID SWITCH BEING IN AN OPEN POSITION IN WHICH POSITION SAID TONE GENERATOR IS DEACTIVATED WHEN SAID TONE SELECTOR IS IN ITS NORMAL REST POSITION, A TRANSISTORIZED AMPLFIIER FOR AMPLIFYING THE OUTPUT OF SAID TONE GENERATOR, A POWER SUPPLY FOR SAID AMPLIFIER CONNECTED THERETO THROUGH A SECOND SWITCH ALSO OPERATED BY SAID TONE SELECTOR, SAID SECOND SWITCH NORMALLY BEING IN AN OPEN POSITION IN WHICH POSITION SAID AMPLIFIER IS DEACTIVATED WHEN SAID TONE SELECTOR IS IN ITS NORMAL REST POSITION, SAID FINGER-OPERATED TONE SELECTOR BEING ADAPTED, ON APPLICATION OF INITIAL FINGER PRESSURE THERETO, TO DETERMINE THE TONE GENERATED BY SAID GENERATOR, ON THE APPLICATION OF FURTHER FINGER PRESSURE THERETO, TO CLOSE SAID SWITCH BETWEEN SAID TONE GENERATOR AND SAID POWER SUPPLY THEREFOR, THEREBY ENERGIZING SAID TONE GENERATOR, AND ON APPLICATION OF YET FURTHER FINGER PRESSURE THERETO, TO CLOSE SAID SECOND SWITCH BETWEEN SAID AMPLIFIER AND SAID POWER SUPPLY THEREFOR, THEREBY ENERGIZING SAID AMPLIFIER, WHEREBY THE OUTPUT OF SAID MUSICAL INSTRUMENT IS DEVOID OF KEY CLICKS AND IS COMPLETELY SILENT WHEN NOT GENERATING A TONE.
