Abstract
A digital wireless earphone device with stereo or multiple-channel sound effect automatic detection and switching functions is provided. The multiple-channel digital wireless earphone device uses a signal processing and transmitting device to decode multiple-channel signal sources. After the decoding is completed, the multiple-channel signal sources are concurrently transmitted to a wireless earphone end through a radio. After being directly digital-to-analog converted and amplified, the multiple-channel signals are connected to a plurality of speakers to generate a multiple-channel surround sound field. The wireless earphone at a receiving end further has an automatic detection function for detecting a 6CH or 2CH sound source and automatically selects an earphone playing mode accordingly.
