Abstract: An earphone set includes a main device having a digital signal processor, and an earplug has an external microphone and a speaker electrically connected with the digital signal processor respectively. The external microphone converts an external sound wave into an electronic signal and transmits the electronic signal to the digital signal processor for processing. The speaker converts the electronic signal processed by the digital signal processor into a sound wave for output.

Abstract: An earpiece device includes a housing having a sound output portion, a speaker and a microphone. The speaker disposed in the housing includes a diaphragm and a sound transmitting hole. The diaphragm is located between the sound output portion and the sound transmitting hole. The microphone is disposed in the housing and covers the sound transmitting hole. A sound wave generated within an ear canal would be received by the speaker and delivered through the sound transmitting hole to the microphone for pickup.

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.
