Method of controlling an acoustic noise reduction audio system by user taps
First Claim
1. A method for controlling an audio system, the method comprising:
- tapping at least one of a headphone worn by a user or an ear or a head of the user to cause an acoustic pressure change in an ear canal of the user, the ear canal being substantially sealed by an acoustic noise reduction (ANR) headphone having an ANR module;
sensing a current provided to the ANR module, the current being responsive to a pressure change in the ear canal;
determining a first peak in the sensed current; and
determining that a dual tap occurred if a second peak in the sensed current is determined during a first time window initiated at the determination of the first peak.

Abstract
Described are a headphone and a method for controlling an audio system. The method includes tapping a headphone, ear or head of a user to cause an acoustic pressure change in an ear canal of the user wherein the ear canal is sealed by an acoustic noise reduction (ANR) headphone having an ANR module. A current that is responsive to a pressure change in the ear canal and provided to the ANR module is sensed. A first peak in the sensed current is determined. A dual tap is determined to have occurred if a second peak in the sensed current is determined during a first time window initiated at the determination of the first peak. The use of dual taps for controlling an audio system can prevent unintended changes to an audio system that may otherwise occur as a result of an accidental or unintended tap for an audio system utilizing single tap control.

12. A headphone comprising:
-
a microphone for detecting a pressure change in a substantially sealed cavity of the headphone, the cavity comprising an ear canal of a wearer of the headphone; an acoustic noise reduction (ANR) module coupled to the microphone for generating a noise cancellation signal to cancel noise detected by the microphone; and a processor in communication with the microphone and the ANR module, the processor configured to; sense a current provided to the ANR module, the current being responsive to a pressure change in the ear canal; determine a first peak in the sensed current; and determine that a dual tap occurred if a second peak in the sensed current is determined during a first time window initiated at the determination of the first peak. - View Dependent Claims (13, 14, 15, 16, 17, 18)
