Problems solved by technology

[0002] At present, most wireless speakers are Bluetooth wireless speakers, which use Bluetooth technology based on wireless transmission of audio files. However, with the development of Bluetooth 4.0 technology, Bluetooth technology still has not solved the problems of short transmission distance, limited transmission speed, high distortion and low quality. Disadvantages; In addition, Bluetooth wireless speakers usually can only transmit audio files, but there is no audio decoding function, which has certain requirements for the audio decoding ability of the source device, and there is no way to transmit some high-quality lossless music
