Abstract

Abstract A hand-held electronic sound generator, comprising a one or more oscillators and a noise generator, each acting singly, mixed or gated in combination to produce a variety of interesting sounds. The device may be operated continuously or as a momemtary pulse with decaying volume. Power is used only when sounds are being generated to conserve battery power. The frequency of the oscillators or noise generator may be varied to change the characteristics of each individual sound combination.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 203 words
A circuit for generating a plurality of sounds in dependance on operator control, powered by an electrical power source and comprising: audio signal generator means including noise generator, low frequency audio oscillator, voltage controlled oscillator and mixing means for mixing the outputs of the noise generator, low frequency oscillator and voltage controlled oscillator; amplifier means for amplifying the output of said audio signal generator; sound selector means coupled to said mixing means, said selector means adapted for operator selection of the respective ones of said noise generator and said oscillators to be mixed; pitch control means coupled to said voltage controlled oscillator, adapted for operator control of the pitch of said voltage controlled oscillator; oscillation rate control means coupled to said low frequency oscillator, adapted for operator control of the oscillation rate of said low frequency oscillator; and audio transducer means coupled to the audio output of said audio amplifier means; all of said above means adapted for inclusion in a housing to be hand-held by operator, the sound generating circuit further comprising switch means for coupling such electrical power source to the circuit, said switch adapted to provide power to the circuit only when held in a closed position by the operator.
