Abstract

The present invention provides an audio processing device, audio crosstalk processing method and device, the audio processing device includes: an audio processing chip, a control switch and an audio output interface; the audio processing chip includes: a first power amplifier and a second power amplifier; the first power amplifier , used to output the left channel signal; the second power amplifier, used to output the right channel signal; the control switch, coupled with the common negative terminal of the first power amplifier and the second power amplifier, is used to feed back the reference feedback signal to the common negative terminal , and connect the signal of the headphone of the audio output interface to the ground of the main board, wherein the reference feedback signal is obtained by voltage sampling the signal of the headphone. Through the present invention, the problem that the audio processing device provided in the related art is likely to cause excessive crosstalk between channels and affect the user's listening experience is solved, and the crosstalk index is improved so that when listening to high-quality HiFi music with headphones , to achieve a stronger sense of space.

Description

technical field [0001] The present invention relates to the communication field, and in particular, to an audio processing device, an audio crosstalk processing method, and a device. Background technique [0002] In recent years, high-fidelity (HiFi), as people's pursuit of high-quality music enjoyment, has been paid more and more attention. The high-fidelity capabilities of many HiFi professional playback devices and playback devices have reached a very high level. However, due to the expensive price of HiFi professional equipment, the penetration rate is low. With the rapid popularization of smart phones, many brands of smart phones have claimed to have the ability to decode and play HiFi. The audio output interface of the smartphone mainly includes a 3.5mm headphone jack and a USB Type-C interface. Almost all the input interfaces of audio playback devices are 3.5mm headphone jacks, which means that if you use the USB Type-C interface to transmit music on a mobile phone...
