Abstract

The invention discloses an audio power amplification system, which is characterized in that it mainly consists of a preamplifier circuit, a triode VT2, a current limiter, the positive pole is connected with the preamplifier circuit, and the negative pole is connected with the input end of the current limiter. Capacitor C3, one end is connected to the collector of the triode VT2, the other end is grounded resistor R5, a power amplifier circuit connected to the emitter of the triode VT2, the positive pole is connected to the preamplifier circuit, and the negative pole is connected to the power amplifier circuit Capacitor C4, and inductance L1 connected in series between the preamplifier circuit and the emitter of the triode VT2. The present invention can amplify the audio signal, and the present invention has a stable static operating point, so as to ensure that the waveform of the amplified audio signal is the same as that of the pre-amplified audio signal, and avoid the distortion of the audio signal after the amplification, resulting in signal Distortion, thereby ensuring the quality of sound playback.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an audio power amplification system. Background technique [0002] As people pursue higher and higher quality of life, home theater has basically entered every household, which brings great joy to people's life. High-definition sound quality can improve the viewing effect, so the audio power amplification system used in the home theater is particularly important. However, when the traditional audio power amplification system amplifies the audio signal, it is easy to cause distortion of the audio signal, which largely affects the quality of sound playback. Contents of the invention [0003] The object of the present invention is to overcome the defect that the traditional audio power amplifying system easily causes audio signal distortion when amplifying the audio signal, and provides an audio power amplifying system. [0004] The object of the present invention is achieved through ...
