摘要： An ear piece device configured for being supported in the ear and providing a microphone which primarily detects only sounds originated by the user is contained within a housing which is configured at one end to fit snugly at the ear canal of the user, but not to extend within the ear canal. A microphone element is coupled within the housing in a position such that the microphone element is separated from contact with the skull of the user by the housing. This microphone element is contained within a casement which is mechanically and acoustically isolated from vibrations occurring within the housing. Mounting rings formed of acoustical absorbing materials are interposed around the casement and between the housing and casement in a displaced configuration on opposing ends of the casement to result in cancellation of residual vibrations passing to the microphone element from the housing. A speaker element may be included within the ear device and can be decoupled acoustically so as to avoid feedback. This system can operate with full duplex and enable hands free communication and direct voice command by user through computer modems, telephone networks and other communication systems.

摘要： A method is disclosed for increasing a parametric output of a parametric loudspeaker system. The method can include the operation of providing multiple ultrasonic frequency emission zones that output signals in a frequency band. The phase relationships of the ultrasonic frequency emission zones can be correlated and controlled to increase phase coherence between each ultrasonic frequency emission zone to maximize parametric output. Correlating and controlling the phase relationships can include offsetting a frequency of a carrier signal applied to each emission zone from a resonant frequency of each emission zone in view of a rate of change of phase of each emission zone in a vicinity of each resonant frequency. Ultrasonic energy from the ultrasonic frequency emission zones can be generated, using the correlated phase relationship to increase the parametric output.
