Abstract

The invention provides an audio processing device, an audio crosstalk processing method and an audio crosstalk processing device. The audio processing device comprises an audio processing chip, a control switch and an audio output interface, the audio processing chip comprises a first power amplifier and a second power amplifier. The first power amplifier is used for outputting a left channel signal; the second power amplifier is used for outputting a right channel signal; the control switch is coupled with the common negative end of the first power amplifier and the second power amplifier andused for feeding back a reference feedback signal to the common negative end and connecting an earphone ground signal of the audio output interface with the main board ground, and the reference feedback signal is obtained by conducting voltage sampling on the earphone ground signal. By means of the audio processing method and device, the problems that crosstalk between sound channels is likely tobe too large and the listening experience of a user is affected by an audio processing device provided in the related technology are solved, and the effect of improving the crosstalk index so that when the earphone is used for listening to high-quality HiFi music, the stronger space sense can be obtained can be achieved.

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...
