Microphone headset failure detecting and reporting

Abstract

Embodiments of the invention include methods, apparatus, and systems for detecting a predicted future or current failure of a microphone of a headset. The failure may have been caused by organic matter buildup creating a signal path or short circuit across the microphone's circuitry. The headset is connected to a mobile device having a network interface that is used to send a notification message to a remote supply management system server. A failure detection circuit detects the failure based on a decrease in a microphone bias signal or increase in headset temperature over time. In some cases, the failure is based on an increase in a microphone bias signal over time. Upon detection of the failure, it signals that a failure notification be transmitted to the remote supply management system. The notification may then cause a new headset to be sent to the owner of the mobile device. Other embodiments are also described and claimed.
