The engineers at Knowles Corp. (NYSE: KN) said they have developed the world´s first digital microphone supporting ultrasonic bandwidth.
This new product allows the microphone to assist smartphones and consumer electronics with touch-less gesture recognition, phone-to-phone data transmission, pen input compatibility for handsets and tablets, and 3D positioning input.
To facilitate these capabilities, the new MEMS (micro-electro-mechanical systems) microphone can receive ultrasonic sound waves above the audible range of humans, up to 80 kHz, and use those waves to triangulate an object´s location and movement. The technology principles are similar to radar or an ultrasound administered by a doctor during pregnancy.
Beyond the ultrasonic mode, the microphone offers four performance modes, including a low power voice activation mode, which is ideal for mobile consumer electronics.
