Abstract

The invention discloses an audio processing system for widening a range. The system is mainly composed of an audio collection module, a frequency selecting circuit, a micro-processing circuit, a current source circuit and an amplifying circuit, wherein the micro-processing circuit and the current source circuit are both connected with the frequency selecting circuit, and the amplifying circuit is connected with the micro-processing circuit and the current source circuit at the same time. The system is characterized in that a low-frequency intensifier circuit is arranged between the audio collection module and the frequency selecting circuit and composed of a resistor R1, a potentiometer R2, a resistor R3, a resistor R4, a resistor R5, a potentiometer R6, a capacitor C1, a capacitor C2, a capacitor C3 and a capacitor C4. The low-frequency intensifier circuit is arranged, powerful low sound can be acquired, the range can be widened within the wide scope, and the low sound effect of a home theater is better in the film showing process.

Description

technical field [0001] The invention relates to an audio processing system, in particular to an audio processing system based on a triode common-emitter symmetrical amplifying circuit. Background technique [0002] With people's pursuit of higher and higher quality of life, home theaters have basically entered every household, bringing great joy to people's lives. High-definition sound quality can improve the viewing effect, so the audio processing system used in the home theater is particularly important. However, in the actual viewing process, when people turn up the sound, there will always be a lot of noise, which will affect the viewing effect. Therefore, it is particularly important to provide a stable audio processing system to solve the above problems. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the current audio processing system is prone to signal instability after amplifying the audio signal, and to pr...
