Abstract

A wireless earphone system includes a main device and two ear-hang devices. The main device having a digital signal processor, a server-end wireless transmitting module and a server-end wireless receiving module electrically connected with the digital signal processor respectively. Each ear-hang device has a microphone, a speaker, a client-end wireless transmitting module electrically connected to the microphone and a client-end wireless receiving module electrically connected to the speaker. The microphone collects an external sound wave and converts the external sound wave into an electronic signal for transmission to the digital signal processor by the client-end wireless transmitting module and the server-end wireless receiving module, and the processed electronic signal is transmitted by the server-end wireless transmitting module and the client-end wireless receiving module to the microphone for converting into a sound wave.

Claims

1. A wireless earphone system comprising:

a main device having a digital signal processor, a server-end wireless transmitting module and a server-end wireless receiving module, the digital signal processor being electrically connected with the server-end wireless transmitting module and the server-end first wireless receiving module; and

two ear-hang devices, each of which includes a microphone, a speaker, a client-end wireless transmitting module and a client-end wireless receiving module, the client-end wireless transmitting module being electrically connected with the microphone, the client-end wireless receiving module being electrically connected with the speaker;

wherein the microphones collect external sound wave and convert the external sound wave into an electronic signal;

the client-end wireless transmitting modules transmit the electronic signal from the microphones to the server wireless receiving module;

the server-end wireless receiving module transmits the electronic signal to the digital signal processor for processing;

the digital signal processor transmits the processed electronic signal to the server-end wireless transmitting module for transmission to the speakers via the client-end receiving modules for converting into sound wave.

2. The wireless earphone system as claimed in claim 1, wherein the digital signal processor has at least one of the functions of filtering and amplification.

3. The wireless earphone system as claimed in claim 1, wherein the transmission interface between the main device and the ear-hang devices is one of the transmission interfaces of infrared rays, radio frequency and bluetooth.

4. The wireless earphone system as claimed in claim 1, wherein the main device further comprises a bluetooth module for communication with a mobile phone.
