Problems solved by technology
[0003] However, since a TV usually only has two-channel speakers (i.e. a left speaker and a right speaker), the sound effect of the above method (1) is difficult to reproduce the original multi-channel effect, especially the serious loss of sound image and sense of presence ; and the above method (two) needs to cooperate with the external multi-channel audio equipment to reproduce the original multi-channel effect
For example, when the multi-channel audio source input by the TV is 5.1-channel audio, the external multi-channel audio equipment needs 6 independent speakers to realize the original multi-channel effect of the 5.1-channel audio; When the multi-channel audio source input by the TV is 7.1-channel audio, the external multi-channel audio equipment needs independent 8-channel speakers to realize the original multi-channel effect of the 7.1-channel audio; that is, the above Method (2) has the defects of more hardware components and higher hardware cost

The invention discloses a TV sound system. The TV sound system comprises an audio signal source gating input module used for inputting a multichannel audio signal source; a decoder used for decoding the multichannel audio signal source; a first sound mixing module used for performing sound mixing on left channel audio output by decoding with middle channel audio to obtain a first new left channel audio signal; a second sound mixing module used for performing sound mixing on right channel audio output by decoding with middle channel audio to obtain a first new right channel audio signal; a first power amplifier used for amplifying the first new left channel audio signal; a second power amplifier used for amplifying the first new right channel audio signal; a left channel loudspeaker used for outputting the amplified first new left channel audio signal; and a right channel loudspeaker used for outputting the amplified first new right channel audio signal. The TV sound system disclosed by the invention can replay a multichannel effect and has the advantages of low hardware cost.
Description
technical field [0001] The invention relates to the field of televisions, in particular to an audio system of a television. Background technique [0002] In the prior art, there are usually the following two processing methods for television sets to 5.1-channel audio and 7.1-channel audio or even more audio channels (such as 9.1-channel audio and 11.1-channel audio): (1) TV sets Decode the input multi-channel audio, then mix the decoded audio of each channel, mix it into left channel audio and right channel audio, and then emit sound from the left and right speakers of the TV set;( 2) The TV does not decode multi-channel audio, but outputs the source code of the input multi-channel audio to an external multi-channel audio through the corresponding audio interface (such as HDMI ARC, optical fiber interface or coaxial audio interface) The external multi-channel audio equipment decodes the multi-channel audio, and the decoded audio of each channel emits sound through the corre...
