Abstract

The invention discloses a tone control circuit which comprises a first polar capacitor to a fourth first polar capacitor, a first non-polar capacitor to a fourth non-polar capacitor, a first resistor to a tenth resistor, a first triode, a second triode, a first adjustable resistor, a second adjustable resistor and a direct-current power supply. The first polar capacitor and the first resistor form an input filter circuit, the second polar capacitor, the second resistor and the first triode form an emitter following circuit, the third resistor, the fourth resistor, the fifth resistor, the first adjustable resistor and the second non-polar capacitor form a low-pitch control circuit, and the first non-polar capacitor, the third non-polar capacitor, the second adjustable resistor and the sixth resistor form a high-pitch control circuit. The tone control circuit is simple in circuit structure, high in reliability, wide in adjustment control range, low in noise and small in distortion. Amplitude variation of alto voice cannot occur obviously during adjustment of strength of high pitch and low pitch, and the tone control circuit is good in performance.

Description

technical field [0001] The invention relates to a tone control circuit, in particular to a tone control circuit with low noise and little distortion. Background technique [0002] The frequency characteristics of electronic circuits are due to the existence of impedance components in the circuit. In fact, the signals input in wireless communication, broadcast television and other electronic systems are not a single frequency, but contain multiple frequencies, resulting in many parameters of the amplifying circuit. are functions of frequency. The tone control circuit uses the principle of frequency characteristics of electronic circuits to adjust the tone in time to meet various listening requirements, and to compensate for recording defects of the sound source or the frequency response of the speaker. Current tone control circuits are noisy and distorted. Contents of the invention [0003] The object of the present invention is to provide a tone control circuit with low ...
