Problems solved by technology
[0005] At present, in order to improve the sound quality of the audio equipment of small home appliances, the audio is mainly adjusted through a treble regulator or an audio equalizer. However, this adjustment needs to be equipped with a treble regulator or an audio equalizer component, and its wiring and operation It is relatively complicated, and it is difficult for non-professional personnel to adjust to a better audio quality, which affects the application range of this type of product

Embodiment Construction
[0018] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0019] figure 1 , firstly the audio enters the audio effector through the audio input port 1, the audio signal first passes through the bass filter 2, and the bass filter 2 filters the input signal, the filtering range is 20Hz-200Hz audio, and then some bands will be filtered and the bands of the unfiltered part are sent to the bass audio integrator 3, and the bass audio integrator 3 connects the bands filtered by the bass filter with the bands of the unfiltered part, and at the same time performs a certain gain amplification on the bass audio, The audio signal is sent to the treble filter 4 afterwards, and the treble filter 4 screens the high-frequency part of the audio signal, and then the signal is sent to the tr...

The audio effect device is characterized by comprising an audio input port, a low audio frequency filter, a low audio frequency synthesizer, a high audio frequency filter, a high audio frequency synthesizer, an audio output port, a speaker and a wire. The low audio frequency filter and the high audio frequency filter only filter and screen bands within the low audio frequency range and the high audip frequency range. The filtered and the unfiltered audios are synthesized through the audio synthesizer, and the filtered audio is compensated within a certain range to make sure that the signals of the low pitch part and the high pitch part of the audio signals sent to the signal output port are relatively pure, thus compensating the audio adjustment effect of the high and low pitch regulator or the audio equalizer to a certain degree. The device can compensate the low frequency and the high frequency audios, improve the authenticity of the audio reproduction and give the user good audio quality.
Description
technical field [0001] The invention relates to an audio processor, in particular to a device capable of processing low-frequency and high-frequency sounds. Background technique [0002] With the development of society, social culture is becoming more and more elegant culture, people's quality of life is also improving day by day, and people's pursuit of sound quality is getting higher and higher. [0003] The bass frequency refers to the sound with a frequency of 20Hz-120Hz, and the high-frequency sound refers to the sound with a frequency of 16kHz-20kHz. There are various household small-signal audio output devices, such as MP3, MP4, CD, etc., such audio Output devices, especially some low-end audio output devices, seldom consider the loss of high audio and low audio in the process of sound reproduction, thus affecting the quality of audio reproduction. In the existing literature, it is found that appropriate compensation for high-frequency and low-frequency signals can i...
