Problems solved by technology
[0002] With the portable requirements for audio equipment, the overall appearance of audio equipment tends to be more and more miniaturized. Therefore, for most portable audio equipment, the internal speaker space is usually relatively small, and the speaker wire inside the speaker The larger occupied volume makes the effective sounding space of the speaker smaller, and the smaller the sounding space, the lower the bass effect; and the speaker wire cannot be fixed in the box, and it is also prone to vibrating sound, which will greatly affect the sound quality of the audio equipment

The invention discloses sound equipment and an audio signal transmission circuit thereof. The audio signal transmission circuit is connected between the audio signal amplification module and the loudspeaker; The audio amplifier comprises an audio signal input end, an audio signal frequency division unit and an audio signal output end, wherein one end of the audio signal input end is connected withthe output end of the audio signal amplification module, the other end of the audio signal input end is connected with the input end of the audio signal frequency division unit, the output end of theaudio signal frequency division unit is connected with one end of the audio signal output end, and the other end of the audio signal output end is connected with the loudspeaker; A traditional tangible loudspeaker line transmission mode is replaced with a PCB transmission mode, and an audio signal frequency division unit is integrated, so that the layout space in the sound equipment can be saved;Moreover, the impedance of audio signal transmission is effectively controlled, the vibration phenomenon is avoided, and the sound quality effect of the sound equipment is effectively improved.
Description
technical field [0001] The invention belongs to an audio equipment, and in particular relates to an audio equipment and an audio signal transmission circuit thereof. Background technique [0002] With the portable requirements for audio equipment, the overall appearance of audio equipment tends to be more and more miniaturized. Therefore, for most portable audio equipment, the internal speaker space is usually relatively small, and the speaker wire inside the speaker The large occupied volume makes the effective sounding space of the speaker smaller, and the bass effect will be poor if the sounding space is small; and the speaker wire cannot be fixed in the box, and it is easy to produce vibration, which will greatly affect the sound quality of the audio equipment. Contents of the invention [0003] In view of the above problems, the present invention provides an audio signal transmission circuit, which is connected between the audio signal amplification module and the spe...
