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

Embodiment Construction

[0018] now refer to Figure 1A , a personal audio device 10 is shown proximate to a human ear 5, as shown in accordance with an embodiment of the present disclosure. Personal audio device 10 is an example of a device that may employ techniques in accordance with embodiments of the present invention, but it should be understood that not all of the elements or configurations embodied in the illustrated personal audio device 10 or the circuits shown in subsequent diagrams are required in order to The invention stated in the claims is carried out. The personal audio device 10 may include a transducer, such as a speaker SPKR, that reproduces distant speech received by the personal audio device 10, as well as other local audio events, such as ringtones, stored audio program material, audio to provide a balanced conversational feel. Injection of near-end speech (i.e., the voice of the listener of the personal audio device 10) and other audio that needs to be reproduced by the persona...

Abstract

The processing circuit may determine whether the earphones are engaged with the listener's respective ears based on the transducer state input signal indicative of whether the earphones housing the respective transducers are engaged with the listener's ears. In response to determining that at least one of the earphones is not engaged with its corresponding ear, the processing circuit may modify at least one of the first output signal of the first transducer and the second output signal of the second transducer The output signal is such that at least one of the first output signal and the second output signal is different from such a signal if the earphones 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 ...
