The application describes systems for deriving haptic and audio drive signals from an input signal received via a single channel such as an audio channel.

Haptic output systems

A system () for binaural signal processing. A first speaker () and a second speaker () are respectively mounted proximal to, and deliver respective first and second acoustic signals to, the left and right ears of a user. A first microphone () and a second microphone () are respectively mounted proximal to the left and right ears. A binaural processing device receives signals from the microphones and, based on the microphone signals, determines the first and second acoustic signals. The binaural processing device operates at a distance from both the left and right ears of the user. The speakers, microphones and the binaural processing device are connected by a signal network.

Binaural hearing system and method

The overall performance and power utilization of an audio device may be improved with an adaptive sidetone generation system that generates sidetones optimized for different application-specific problems. In particular, systems that include sidetone generation capabilities may be developed to include numerous microphones from which information may be received and processed to generate optimized sidetones. For example, the information from the microphones may be used to receive and/or determine the audio device's operating mode. The information from the microphones and the received and/or determined mode may then be used to generate a sidetone that is optimized for the particular mode and particular conditions in which the audio device is operating. Through the generation of optimized sidetones, the audio signal quality may be improved, thus reducing the amount of subsequent audio processing required, and resulting in improved performance and power utilization.
