DEVICE AND METHOD FOR REMOTE ACOUSTIC PORTING AND MAGNETIC ACOUSTIC CONNECTION
摘要
An earpiece device includes a microphone and a speaker having a common acoustic channel to reduce complexity and minimize components in an ear canal region. The earpiece device also includes a logic circuit operatively connected into an earpiece, where the microphone is configured to sample an acoustic signal traveling from either end of an acoustic channel. The earpiece device further includes a selective attenuation mechanism for varying the acoustic energy from one end of the acoustic channel or combining the acoustic energies in a controlled ratio from both ends of the acoustic channel before reaching the microphone.
