Embodiment Construction
[0033] In order to better understand the technical solutions provided by the embodiments of the present application, the application scenarios of the embodiments of the present application are first introduced below. With the continuous development of terminal technology, electronic devices such as mobile phones, tablets, and personal computers usually have audio playback functions. For example, users can listen to music through the terminal and listen to various audio information in audio and video while watching audio and video files. Therefore, how to improve the sound effect of audio played by the terminal is becoming more and more important for improving user experience. For example, users now hope to hear audio with less noise and better stereo sound effect through the terminal. The embodiment of the present application is intended to solve the problem of crosstalk between the left channel and the right channel in a terminal with an audio playback function, improve the is...

The embodiment of the present application discloses an audio chip and a terminal, which are used to solve the problem of crosstalk between the left and right channels in a playback device, and improve the isolation between the left and right channels. The audio chip is applied to a terminal with a device interface. The device interface is used to connect to a playback device. The playback device includes a left-channel playback device and a right-channel playback device. The power of the signal is amplified to obtain the left channel output signal, and output to the left channel playback device through the device interface; the right channel circuit is used to amplify the power of the obtained right channel signal to obtain the right channel output signal, and through the device The interface is output to the right channel playback device; the control circuit includes a sampling unit and a feedback unit, the sampling unit is connected in series to the ground loop of the audio chip, the feedback unit is used to collect the voltage of the sampling unit, and obtain the feedback voltage accordingly, the feedback voltage It is the input feedback signal for the left channel circuit and the right channel circuit.
Description
technical field [0001] The present application relates to the technical field of terminals, in particular to an audio chip and a terminal. Background technique [0002] When a user uses a terminal to play an audio file, a stereo playback device (such as a two-channel headset) can be used for audio output. Because the signals played by the left channel and the right channel of the stereo playback device are different, a stereo sound field effect can be constructed. Loved by users. However, due to the influence of audio cables and electronic components, the left and right channels of a stereo playback device will inevitably introduce signal crosstalk (crosstalk), that is, the left channel signal contains components of the right channel signal and the right channel signal. The channel signal contains components of the left channel signal, which affects the audio playback effect and the user's subjective hearing experience. [0003] Taking the stereo playback device as a two-c...
