Abstract:
1. A method for providing an audio signal to first and second ears of a user by using a single earpiece, the method comprising: receiving an input signal that comprises a first input signal and a second input signal; wherein the first input signal the second input signal are desired signals and do not include ambient noise; injecting the first input signal to a bone conductor speaker of the single earpiece, wherein the single earpiece is positioned on the second ear of the user; outputting an output signal by the bone conductor speaker in response to the first input signal; wherein the outputting of the output signal causes an audio signal to reach the first ear of the user and causes a leakage signal to reach the second ear of the user; filtering the first input signal by an adaptive filter to provide a filtered signal that once played to the second ear of the user by an in-ear speaker of the single earpiece reduces an audio effect of the leakage signal on the second ear of the user; sending, to an in-ear speaker of the single earpiece, the filtered signal and the second input signal; providing an in-ear audio signal to the second ear of the user, by the in-ear speaker, in response to the filtered signal and the second input signal; sensing, by an in-ear microphone of the single earpiece, a sensed audio signal; and updating an impulse response of the adaptive filter in order to reduce a contribution of the leakage signal to the sensed audio signal.
