Abstract

An analgesic noise generator employs a circuit that can be switched to provide a variable waveform from an active noise source out of an integrated circuit amplifier.

Claims

1. A random noise generator and transmitter comprising:

a source of electrical energy;

a switch for control of said source;

source via

a noise generating means connected to said source via said switch means to be productive of electrical noise;

a means to broadcast electrical noise including a speaker and an insulated gate element connected to said speaker and to a resistance capacitance circuit in series with said insulated gate element and said speaker to said source via said switch, said insulated gate element having at least one gate connected to said noise generating means;

a divide circuit connected to said noise generating means and said source of electrical energy; and

a modulator circuit connected to said divide circuit and said source of electrical energy, said modulator circuit having an output terminal connected to another gate of said insulated gate element so as to control the desired waveform from said means.

2. A device for producing a soothing noise, said device including:

first means to generate random noise;

a variable volume control controlling level of random noise from said first means;

second means connected to said first means to receive random noise thereform, said second means being a divider circuit to divide said random noise into cycles of repetitive pusles; and

third means to transmit said random noise in accordance with said pulses, said third means to transmit comprising a MOS FET element having one gate connected to the variable volume control connected to said first means and another gate to said second means whereby the repetitive pulses of said second means controls the transmission of the random noise from said first means by said third means.

3. The device of claim 2 and further characterized by a modulator circuit between said second and third means to provide an equal rate of gain increase and decrease, a steady gain and a first rate of increase and a different rate of decrease of the gain for said MOS FET.

4. A portable noise generator and transmitter comprising:

a housing including a pocket;

an electrical source within said housing;

noise generating means in said housing;

a divide circuit in said housing, said divide circuit connected to said noise generating means to divide same into repetitive pulses;

insulated gate means in said housing having one gate connected to said noise generating means and another gate connected to said divide circuit;

a modulator circuit between said divide circuit and said insulated gate means to provide an equal rate of gain increase, a steady gain and a first rate of increase and a different rate of decrease of the gain of the repetitive pulse of said divide circuit in obtaining the desired waveform from said insulated gate means of said noise generating means;

a speaker to broadcast the product of said noise generating means via said insulated gate means, said speaker being stowable in the pocket of said housing; and

control means on said housing to connect said electrical source to turn on and off said noise generating means said divide circuit and said modulator circuit and to control volume of said noise of said noise generating means.
