ACOUSTIC PATH FOR A WIRELESS COMMUNICATIONS DEVICE

摘要

A printed circuit board (20) for a wireless communications device (10) includes an acoustic path (30), and acoustically couples microphone circuitry (28) mounted to a surface of the printed circuit board (20) to an exterior of the wireless communications device (10). A portion of the acoustic path (30) is integrally formed with the printed circuit board (20) and extends generally parallel to the surface of the printed circuit board (20). One end of the acoustic path (30) is disposed proximate the microphone circuitry (28) and an opposing end opens to receive acoustic sound from the exterior of the wireless communications device (10). Audible sound propagates through the acoustic path (30) to the microphone circuitry (28).
