Abstract
An ultrasonic emitter is provided, where at least one of an amplifier, driver circuit, and signal processing circuitry is integrated onto or into the ultrasonic emitter. The ultrasonic emitter may include a backing plate and an amplifier and/or associated processing integrated directly onto the backing plate for amplifying and matching an audio modulated ultrasonic carrier signal to the ultrasonic emitter. The emitter is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air.
Claims21
An ultrasonic emitter configured to launch a pressure-wave representation of an audio modulated ultrasonic carrier signal into the air, comprising:
- a backing plate;
- an amplifier integrated directly onto or into the backing plate for amplifying the audio modulated ultrasonic carrier signal;
- and
- a pair of signal lines carrying the audio modulated ultrasonic carrier signal from the amplifier to a emitting element for the launching of the pressure-wave representation of the audio modulated ultrasonic carrier signal into the air.
An ultrasonic emitter, comprising:
- a first pole comprising a conductive element having a textured surface disposed on a backing plate;
- a second pole comprising a metalized film disposed adjacent the textured surface of the first pole, wherein upon application of an audio modulated ultrasonic carrier signal amplified by an amplifier integrated onto the backing plate, the second pole is configured to resonate in response to an audio modulated ultrasonic carrier signal and to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air.
An ultrasonic emitter, comprising:
- a backing plate comprising a first major surface and a conductive region, the backing plate further comprising a plurality of textural elements disposed on the first major surface;
- a layer disposed adjacent the first major surface of the backing plate, the layer comprising a conductive region and an insulative region, wherein the layer is disposed adjacent the backing plate such that the insulative region is positioned between the backing plate and the conductive region of the layer, and such that there is a volume of air between the layer and surfaces of the textural elements;
- wherein the backing plate and the layer are each configured to be electrically coupled to a respective one of a pair of signal lines carrying an audio modulated ultrasonic carrier signal, and further wherein, upon application of the audio modulated ultrasonic carrier signal the layer is configured to launch a pressure-wave representation of the audio modulated ultrasonic carrier signal into the air.
