Abstract

The invention discloses a power-amplifying recording system based on audio buffering. The system is characterized by being mainly composed of a microprocessor, a memory, a conversion module, an audiofiltering circuit, a timer, an audio collection module, an audio power amplifying circuit, an audio buffering circuit and a loudspeaker, wherein the memory, the conversion module, the audio filteringcircuit and the timer are connected with the microprocessor, the audio collection module is connected with the conversion module, the audio power amplifying circuit is connected with the audio filtering circuit, the audio buffering circuit is connected with the audio power amplifying circuit, the loudspeaker is connected with the audio buffering circuit, and the audio collection module is also connected with the microprocessor. Through the system, interfering noise can be suppressed, needed audio signals are reserved, and therefore the definition of record playing can be increased. The arranged audio power amplifying circuit can amplify the power of the output audio signals, and therefore people can clearly listen to recorded sounds.

Description

technical field [0001] The invention relates to a recording system, in particular to a power amplification type recording system based on audio buffering. Background technique [0002] At present, with the development of science and technology and the needs of people's daily work, study and life, recording equipment has become an indispensable electronic product in various fields. [0003] However, the existing recording equipment will record all kinds of sounds when recording, and it cannot suppress the impurity audio well when processing the audio signal, so when people listen to the recording, they will be subject to a lot of noise. interference; and the loudspeaker of the existing recording equipment is easily damaged by the impact of the signal. Contents of the invention [0004] The purpose of the present invention is to overcome the defect that the existing recording equipment cannot suppress the impurity audio well, and the speaker is easily damaged by the impact ...
