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.
