Embodiment Construction

[0027] see figure 1 , The TV set of the present invention includes a sound processing circuit 100 , a main power amplifier 200 and a sound processing device (5.1 power amplifier) ​​300 .

[0028] Wherein, the main sound output by the sound processing circuit 110 is used as the output channel of the main speaker through the main power amplifier 120;

[0029] In addition, the 5.1 power amplifier 130 also receives and amplifies the sound input from the outside of the TV (not shown in the figure).

[0030] see figure 2 , is a block diagram of the television sound processing device (5.1 power amplifier) ​​of the present invention.

[0031] The 5.1 power amplifier 300 includes an audio input interface part 310 , a power amplifier and output part 320 , a control part 330 , a temperature control part 340 and a power amplifier power supply 5 .

[0032] Wherein, the audio input interface part 310 includes an internal audio input interface ( J3 ) 1 and an external audio input interfa...

Abstract

The invention relates to a voice processing device of television, wherein it comprises: receiving the voice signal from the sound processing circuit of television; outputting the solid voice sound; mixing the left and right sound channels, into the middle signal and left and right loop sound signal; amplifying it via the loop amplifier, base amplifier and middle amplifier to be output; using the power amplify control unit to realize the communication with the processor of main board and the control of power amplification of sound processor; as best, the sound processor can receive the external sound signal to be processed and output. In the disclosed television, the main sound output by the sound processing circuit, via main power amplifier, is used as the output channel of main loudspeaker; the output base sound and left and right sound signals via the sound processing device is transformed into the output of 5.1 sound channel.

Description

technical field [0001] The invention relates to a TV sound processing technology, in particular to a TV sound processing device and a TV using the device. Background technique [0002] With the development of society and technology, various consumer electronic products are becoming more and more popular. For example, the penetration rate of TVs in homes, schools and entertainment venues is quite high; the competition among manufacturers and sellers is also becoming increasingly fierce. . [0003] With the improvement of people's consumption level and living standard, the requirements for TV sets are also getting higher and higher. For example, people hope to enjoy the beautiful sound effect brought by the audio processing part of the TV set. [0004] However, the efficiency of the traditional Class A and B power amplifiers used in ordinary TV sets is low, and large toroidal transformers and good heat dissipation conditions are required. This kind of power amplifiers cannot ...
