Air leak self-diagnosis for a communication device |
摘要 |
A communication device (100) is provided with a technique (400) for self-diagnosing an air leak. The leak is determined without having to open the communication device by applying a temporary excitation signal to the speaker terminals (402) to produce a damped response (404) and then monitoring the damped response (406) of the speaker.
