Embodiment Construction

[0020] The above-mentioned implementation circuit is described in detail below:

[0021] Referring to Figure 1, C101, C102, R101, R102, and U1-A form an ultra-high audio frequency selection circuit; R108, R109, C104, C105, and U2-B form an ultra-low audio frequency selection circuit; R103, R104 . R106, R114, R113, R115, R116, C107, and U3-B form an amplifier circuit; J101 is an audio and video connection plug for audio signal input, which is a lotus-shaped audio and video connection plug in this example; J102 is an audio signal output audio Video connection socket, the lotus-shaped audio and video connection socket is used in this example; J103 is the power input socket. When J101 is inserted into the audio signal output port of household small-signal audio output devices such as CD and VCD, the audio signal can be distributed to ultra-high audio filter frequency selection circuit and ultra-low audio filter through J101, R107, R108, C101, R114, and C100. Frequency selection ...

Abstract

This invention relates to a processing device for super-heavy low voices and super-high voices composed of an audio-video connection plug, super-low voice filter selection circuit, super-low voice amplifier circuit, super-high voice filter selection circuit, super-high voice amplifier circuit, an addition circuit, an amplifier circuit, an audio-video connection socket, a power supply socket and ashell. They are independent of various household small signal audio output devices or audio amplifying devices, and it can also lift the super-low and super-high audio to make up the insufflcent compensation of household small audio output devices to the high and low frequencies.

Description

technical field [0001] The invention relates to an audio processing device, in particular to a processing device for subwoofer and super treble. The subwoofer referred to in the present invention is the subwoofer frequency, also known as the subwoofer, which refers to the audio frequency range of 20Hz to 120Hz; the supertreble frequency refers to the audio frequency range of 16kHz to 20kHz. Background technique [0002] In the prior art, various household small-signal audio output devices such as CD, VCD, etc., do not consider the loss of ultra-high audio and ultra-low audio in the audio recording process in the audio playback process; do not consider the line transmission process during audio playback. loss, especially the loss of ultra-high audio and ultra-low audio; it does not consider the different sensitivities of human hearing to different frequencies in the full-audio range, such as the characteristics of slow response to ultra-low audio. So what is pursued is the f...
