摘要： An ultrasonic emitter can launch an unmodulated ultrasonic carrier signal towards an audio source. The ultrasonic carrier signal, upon being reflected from the audio source, undergoes modulation by the audio source. The modulated ultrasonic signal may then be received by an ultrasonic microphone and demodulated to retrieve the audio. A highly directional microphone system is achieved through the use of the ultrasonic emitter and ultrasonic microphone, where the modulated ultrasonic signal only arises when the audio source is in the ‘beam’ of the ultrasonic carrier signal and the ultrasonic microphone can ignore other potential noise, ambient sound(s), etc.

摘要： A low profile ultrasonic emitter comprises a support member operable to support an ultrasonic emittive material, the support member including a plurality of support ribs, each support rib being spaced from adjacent support ribs and extending longitudinally along the support member. An ultrasonic emittive film is coupled to upper portions of the support ribs so as to be carried by the support member. A first electric lead is coupled to a first face of the emittive film and a second electric lead coupled to an opposing face of the emittive film. The first and second leads are coupled to their respective faces adjacent one another but staggered from one another so as to not overlap one another when the film is positioned between the leads.

摘要： A three-dimensional (3D) sound gaming application can include an ultrasonic sound system, one or more gamers, a gaming console and a throat microphone set. The ultrasonic sound system can include a digital signal processing (DSP) that can adjust the phase, delay, reverb, echo, gain, magnitude or other audio signal component of an audio signal or audio signal components received from the gaming console; an amplifier which can amplify the processed audio signal; and a pair of emitters which can emit ultrasonic signals to each of the gamer's ears to produce a 3D sound effect. The throat microphone set can include a throat microphone which can integrate a low pass filter to attenuate any picked up, ultrasonic carrier frequency signals from the emitted ultrasonic waves. In addition, the throat microphone set can also include an ear speaker piece with one or more apertures for allowing sound produced by ultrasonic waves to enter the gamer's ear canal.
