Abstract

The invention discloses an audio processing system with a phase locking function. The audio processing system mainly comprises an audio acquisition module, a frequency intensifier circuit, which is connected to the audio acquisition module, a frequency selection circuit, which is connected to the frequency intensifier circuit, and a current source circuit, which is connected to the frequency selection circuit. The audio processing system is characterized by further comprising a phase locking circuit, which is synchronously connected to the frequency selection circuit and the current source circuit; the phase locking circuit is formed by a triode VT5, a triode VT6, a triode VT7, a resistor R12, a resistor R13, a resistor R14, a resistor R15, a resistor R16, a resistor R17, a capacitor C8 and a capacitor C9. The phase locking circuit of the audio processing system is capable of locking an audio phase, so that the processed audio frequency is more stable and the sound effect is better.

Description

technical field [0001] The invention relates to an electronic system, in particular to a phase-locked 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. However, in the process of watching movies, because the amplified sound signal of the traditional audio processing system used in the home theater is unstable, it is easy to cause the sound to fluctuate, affecting people's viewing effect. Contents of the invention [0003] The purpose of the present invention is to overcome the defect that the amplified sound signal is unstable in the traditional audio processing system, and provide a phase-locked audio processing system based on a triode common-emitter symmetrical amplifying circuit. [0004] The object of the present invention is achieved with the follow...
