摘要： A printed circuit board (20) for a wireless communications device (10) includesan acoustic path (30), and acoustically couples microphone circuitry (28) mounted to asurface of the printed circuit board (20) to an exterior of the wireless communicationsdevice (10). A portion of the acoustic path (30) is integrally formed with the printed circuitboard (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) andan opposing end opens to receive acoustic sound from the exterior of the wirelesscommunications device (10). Audible sound propagates through the acoustic path (30) tothe microphone circuitry (28).
