Embodiment 1

[0034] Such as image 3 , in this embodiment, the multi-channel downmixing into a wireless two-channel speaker includes a sound effect processing host, a left speaker, a right speaker, and a multi-channel to two-channel unit. In the channel unit, audio output units are provided in the left speaker and the right speaker. The multi-channel to two-channel unit is used to convert more than two-channel audio signals into two-channel audio signals and send them to the audio output unit in a wireless manner. The wireless speaker unit is used to process and amplify the received two-channel audio signal and output it to the speaker output in the left speaker and the right speaker.

[0035] The multi-channel to two-channel unit includes a first main control module, a first wireless sending module, a first wireless receiving module, a first audio output module, a first power supply module and a first storage module.

[0036] The first main control module is used to decode the received ...

Abstract

The invention discloses a sound box for mixing multiple channels to two wireless channels. The sound box comprises a sound processing host, a left sound box and a right sound box. The sound box is characterized by further comprising a multi-channel-to-two-channel unit and audio output units, wherein the multi-channel-to-two-channel unit is arranged in the audio processing host, and the audio output units are both arranged in the left sound box and the right sound box; the multi-channel-to-two-channel unit is used for converting audio signals of more than two channels into two-channel audio signals and sending to the two-channel audio output units through a wireless mode; and the audio output units are used for processing and amplifying the received two-channel audio signals and outputting to a loudspeaker of the left sound box and a loudspeaker of the right sound box. By utilizing the existing two-channel sound box, the multi-channel stereophonic effect is realized, and the sound box can be compatible with the previous wired two-channel system, the wiring is simplified, the space is saved and the cost is low.

Description

【Technical field】 [0001] The invention relates to the field of audio, in particular to a sound box and a method for realizing multi-channel effects by using a 2.0-channel system. 【Background technique】 [0002] With the development of society and microelectronics technology, people's living standards are getting higher and higher, and there are more and more smart devices. Mobile phones, tablets, and large-screen TVs have entered thousands of households. LED large-screen TV connection network online video resources are very rich, and there are various multi-channel video resources on the network, so people have higher and higher requirements for audio equipment or flat-panel TV playback systems with audio functions. At present, the small 2.0 or 2.1 surround sound system of flat-panel TV includes subwoofer host, left speaker, right speaker and subwoofer. figure 1 . Although 2.0 or 2.1 surround sound can meet the needs of users to a certain extent, 2.0 channel stereo or vir...
