Abstract

An audio playing system, an external extension device, and an audio playing method and apparatus, relating to the field of audio processing. The audio playing method comprises: obtaining a user soundsignal acquired by a microphone device (401); receiving, by means of an integrated physical interface connected to a television device, an accompaniment audio signal transmitted by the television device (402); mixing the user sound signal with the accompaniment audio signal (403); and transmitting a mixed signal to the power amplifier circuit of the television device by means of the integrated physical interface, the television device being used for playing, by means of a built-in loudspeaker, the mixed signal received by the power amplifier circuit (404). The present invention solves the problems of the high cost of providing a karaoke processing chip in a television device, and of being inconvenient for upgrading. A karaoke function is integrated into an external extension device, a mixed signal is generated by using the external extension device and transmitted to the television device, and the built-in loudspeaker of the television device plays the mixed signal, so that the manufacturing costs are reduced, and it is convenient to upgrade the karaoke function.

Description

technical field [0001] The present disclosure relates to the field of audio processing, and in particular to an audio playback system, external expansion equipment, audio playback method and device. Background technique [0002] Karaoke (English: Karaoke is a kind of entertainment and leisure method that is deeply loved by users. In order to enable users to experience karaoke at home, more and more TV sets begin to support the karaoke function. [0003] When the user uses the karaoke function of the TV to sing, the built-in karaoke processing chip in the TV obtains the user's voice signal through the microphone connected to the TV, fuses the user's voice signal with the accompaniment audio signal, and converts the fused The audio signal is mixed and processed, and finally the processed mixed signal is played by the power amplifier of the TV, so as to achieve a professional karaoke effect. However, the cost of the built-in karaoke processing chip in the TV is relatively high...
