Detecting the repositioning of an earphone using a microphone and associated action
First Claim
Patent Images
1. An apparatus comprising:
- an earphone that is to be coupled to a host;
a pressure transducer within the earphone; and
a microphone; and
a signaling mechanism coupled to the microphone and the pressure transducer, the signaling mechanism to send to the host a repositioning detection signal representing a pressure change detected by the pressure transducer, the pressure change responsive to repositioning of the earphone, wherein the signaling mechanism is to generate the repositioning detection signal for transmission to the host, the repositioning detection signal generated as a distinct direct current (DC) voltage level upon detection that the microphone is not in use, and as a supersonic distinct alternating current (AC) frequency sequence upon detecting that the microphone is in use.

Abstract
A system detects the repositioning of an earphone that is worn by a user, and changes an operation mode of a host coupled to the earphone. Within the earphone is a pressure transducer that detects a pressure change caused by the repositioning of the earphone. A signaling mechanism sends a repositioning detection signal to the host in response to a signal from the pressure transducer indicating the detection of the pressure change.

10. A method comprising:
-
detecting a pressure change within an earphone, the pressure change responsive to repositioning of the earphone, wherein the earphone is coupled to a microphone; in response to the pressure change, generating a repositioning detection signal to a host that is coupled to the earphone, the repositioning detection signal generated as a distinct direct current (DC) voltage level upon detection that the microphone is not in use, and as a supersonic distinct alternating current (AC) frequency sequence upon detection that the microphone is in use; and sending the repositioning detection signal to the host to cause the host to change an operating mode. - View Dependent Claims (11, 12, 13, 14, 15)
