SYSTEMS AND METHODS FOR ENHANCING PERFORMANCE OF AUDIO TRANSDUCER BASED ON DETECTION OF TRANSDUCER STATUS

摘要

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.

主权项

1. An integrated circuit for implementing at least a portion of a personal audio device, comprising:
a first output configured to provide a first output signal to a first transducer; a second output configured to provide a second output signal to a second transducer; a first transducer status signal input configured to receive a first transducer status input signal indicative of whether a first headphone housing the first transducer is engaged with a first ear of a listener; a second transducer status signal input configured to receive a second transducer status input signal indicative of whether a second headphone housing the second transducer is engaged with a second ear of the listener; and a processing circuit configured to:
based at least on the first transducer status input signal and the second transducer status input signal, determine whether the first headphone is engaged with the first ear and the second headphone is engaged with the second ear; andresponsive to determining that at least one of first headphone is not engaged with the first ear and the second headphone is not engaged with the second ear, modify at least one of the first output signal and the second output signal such that at least one of the first output signal and the second output signal is different than such signal would be if the first headphone was engaged with the first ear and the second headphone was engaged with the second ear.
