Abstract: An earpiece for providing an audio signal to two ears of a user, includes an audio interface for providing the audio signal, a bone conduction speaker coupled to the audio interface for outputting an output signal, an adaptive filter with an adjustable impulse response to provide a filtered signal that once played to the second ear of a user, by an in-ear speaker, reduces an audio effect of the leakage signal on the second ear of the user, an in-ear speaker coupled to the audio interface for providing an in-ear audio signal to the second ear of the user, in response to the filtered signal and the second input signal, an in-ear microphone for sensing a sensed audio signal, and a processor for updating an impulse response of the adaptive filter in order to reduce a contribution of the leakage signal to the sensed audio signal.

Abstract: A system for background sound removal, the system may include: a noise reduction circuit arranged to apply a background sound reduction process on multiple samples of background sound and speech to provide first signals that comprise residual background sound; a background cancellation circuit arranged to remove the residual background sound from the first signals to provide second signals; and an output circuit arranged to output a mixture of the second signals and at least zero selected signals to a sound generating circuit that is arranged to output audio signals representative of the mixture.

Abstract: A sound system, the sound system including: (a) a signal processor that is adapted to generate a first sound signal and a second sound signal, to provide the first sound signal to a loudspeaker; and to provide the second sound signal to a bone conduction speaker; and (b) the bone conduction speaker that is adapted to transduce the second signal to a bone conductible sound signal that is carried in a bone of a user.

Abstract: A wearable surround sound system, that includes: (a) a processor, adapted to receive input signals representative of requested audio signals to be heard by the user and in response to generate multiple output signals; and (b) multiple bone conduction speakers, coupled to the processor, adapted to convey the multiple output signals to at least one bone of a user; wherein the bone conduction speakers are arrayed so as to stimulate an encompassing sound perception of the use. A wearable ambient sound reduction system, that includes: (a) a microphone, adapted to detect an ambient sound signal; (b) a processor adapted to generate an output signal in response to the ambient sound signal; wherein the output signal, when conveyed to a bone of the user, reduces an affect that an ambient sound signal has upon the user; wherein the microphone is coupled to the processor; and (c) a bone conduction speaker, coupled to the processor, adapted to convey the output signal to a bone of a user.
