Systems and methods for enhancing performance of audio transducer based on detection of transducer status

Abstract

Based on transducer status input signals indicative of whether headphones housing respective transducers are engaged with ears of a listener, a processing circuit may determine whether the headphones are engaged with respective ears of the listener. Responsive to determining that at least one of the headphones is not engaged with its respective ear, the processing circuit may modify at least one of a first output signal to the first transducer and a second output signal to the second transducer such that at least one of the first output signal and the second output signal is different than such signal would be if the headphones were engaged with their respective ears.

Description

[0001] Related Application Cross Reference [0002] This disclosure claims priority to US Nonprovisional Patent Application Serial No. 14 / 200,458, filed March 7, 2014, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates generally to personal audio devices and, more particularly, to improving the performance of audio transducers based on detection of transducer status. Background technique [0004] Wireless telephones (such as mobile / cellular telephones), cordless telephones, and other consumer audio devices (such as mp3 players) are widely used. Typically, such personal audio devices are capable of outputting two channels of audio, each channel to a respective transducer receivable in a respective earphone adapted to engage the listener's ear. In existing personal audio devices, the processing and propagation of the audio signal for each of the transducers typically assumes that each earphone is engaged ...

However, in the event that at least one of the earphones is not engaged with the listener's ear (for example, one earphone is engaged with the listener's ear and the other earphone is not engaged with the listener's ear, both earphones are not engaged with any listening neither ear of the listener is engaged, the earphones are engaged with the ears of two different listeners at the same time, etc.), this assumption may not be advisable
