Abstract
Sound effects producer comprises a Zener diode with an inverse voltage impressing circuit connected to the cathode side of the Zener diode for generating a random noise output from the anode of the Zener diode. A speaker system is connected to the anode side of the Zener diode for changing the random output signal to a sound. A control circuit is built into the inverse voltage impressing circuit for controlling the output wave form of that circuit.
Claims2
A sound effects producer comprising a Zener diode semiconductor element, an inverse voltage impressing means for impressing to the Zener diode semiconductor element inverse voltage sufficient to generate output having a random noise component, as an alternating current component from an output side of the semiconductor element, an amplification circuit connected to the output side of the Zener diode semiconductor element for amplifying the output, a speaker connected to the output side of the amplification circuit for converting output amplified by the amplification circuit to audible sound, and a control circuit for controlling the output wave-form of the inverse voltage impressing means, the control circuit comprising an on-off control circuit connected between the Zener diode semiconductor element and the power source of the inverse voltage impressing means, an attenuator for causing attenuation of the output signal from the Zener diode semiconductor element, and a switching circuit to ground the output signal from the Zener diode semiconductor element while the on-off control switch is in the on position.
