Problems solved by technology

A large number of wires are not only expensive but also inconvenient to install and use, damaging the decoration and unsightly, requiring professional installation and debugging
Moreover, for the sake of appearance, most families embed the wiring of the rear left and right surround sound speakers into the wall or the ground when decorating the room. there will be trouble
[0003] There are wireless systems using infrared transmission in the market. Although they are technically unique, they are still not perfect. The main disadvantages are as follows: narrow bandwidth, high requirements for placement, and no obstacles between the host and receiver. Applications are limited and cannot be popularized
[0004] There is also a wireless system that adopts FM frequency modulation. It also has narrow bandwidth, large distortion, narrow frequency response, and is susceptible to interference. At the same time, it has certain interference to TV sets. It is very limited in application and is a relatively backward product.

Embodiment 1

[0019] Embodiment 1. A method for realizing a wireless home theater is to adopt 2.4GH wireless carrier digital transmission between the main power amplifier and the rear left and rear right surround sound channels respectively, and use FHSS frequency hopping expansion in the FSK modulation mode for digital processing Spectrum technology, each transmitter uses 8 different frequency hopping sequences, each sequence has a 7MHz bandwidth, which can ensure sound quality without distortion, and at the same time prevent wireless products such as IEEE802.11, Home Strong interference from RF and Bluetooth etc.

[0020] According to needs, between the power amplifier host and the main channel, center channel, surround channel, and subwoofer channel, 2.4GH wireless carrier digital transmission can be used, and wired transmission can also be used.

Embodiment 2

[0021] Embodiment 2. A wireless 5.1 home theater system, such as figure 1 As shown, including audio source, power amplifier host, stereo 2.4GH wireless transmitter module, surround sound speaker, surround channel 2.4GH wireless receiver module, main channel speaker, main channel 2.4GH wireless receiver module, subwoofer channel speaker, subwoofer Bass channel 2.4GH wireless receiving module, center channel speaker, center channel 2.4GH wireless receiving module. The audio and video signals output by the sound source are amplified by connecting to the power amplifier. The audio and video signals output by the power amplifier are transmitted wirelessly through the stereo 2.4GH wireless carrier digital transmission module. The surround sound speakers include rear left and rear right surround sound speakers. A surround channel 2.4GH wireless carrier digital transmission and receiving module is built in the left and rear right surround sound speakers respectively, and the surround ...

Description

【Technical field】 [0001] The invention relates to a method and system for realizing a wireless home theater, and is especially suitable for a 5.1-channel home theater system. 【Background technique】 [0002] At present, the 5.1-channel home theater systems on the market are all wired connections, that is, no matter the front, center, surround, or subwoofer, speaker cables need to be used to connect to the host. A large number of wire rods are not only expensive but also inconvenient to install and use, damaging the decoration and unsightly, requiring professionals to install and debug. Moreover, for the sake of appearance, most families embed the wiring of the rear left and right surround sound speakers into the wall or the ground when decorating the room. there will be trouble [0003] There are wireless systems that use infrared transmission in the market. Although they are technically unique, they are still not perfect. The main disadvantages are as follows: narrow bandw...
