Problems solved by technology

[0002] At present, drugs or noise maskers are generally used to treat tinnitus at home and abroad, but because the sound source used by the noise masker is natural noise, pure tone or square wave, its effective rate is low, generally below 30%.
Although foreign countries have developed similar more advanced products at present, they have not been widely used because of their high price.

Embodiment Construction

[0008] Noise source circuit 1 is composed of resistor R1 and diode D1, amplifier circuit 2 is composed of integrated block IC1, resistors 2, 3, and 4, and active narrowband filter 3 is composed of integrated circuit IC2, capacitors C1, 2, 3 and resistors R5-8 Composition, high-pass active filter 4 is made up of integrated circuit IC3 resistor R9, 10, capacitor C4, C5. The integrated circuits IC1, IC2 and IC3 adopt general operational amplifiers, and the power amplifier circuit 5 is a general general-purpose circuit. Headphones 6 in figure 2 The middle is R5, the noise source circuit 1 can use any thermal noise when the diode is conducting forward conduction, or the larger noise obtained when the Zener diode works at the inflection point voltage as the sound source, and the resistor R1 is the load resistance of the diode D1 . The signal output by this circuit is provided to the amplifying circuit 2 through the coupling capacitor C1, and the amplified signal is then provided ...

Description

technical field [0001] The invention relates to a medical device for ear diseases, in particular to a tinnitus therapeutic device for noise damage. Background technique [0002] At present, drugs or noise maskers are generally used to treat tinnitus at home and abroad, but because the sound source used by the noise masker is natural noise, pure tone or square wave, its effective rate is low, generally below 30%. Although foreign countries have developed similar more advanced products at present, they have not been widely used because of their high price. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a noise-damaged tinnitus therapeutic device with low cost and high curative effect. [0004] The technical scheme adopted by the present invention to solve the technical problem is: the instrument includes a noise source circuit, an amplifier circuit, an active narrowband filter, a high-pass active filter, a power ...
