AI Technical Summary
Technical Problem
Conventional speakers face challenges in covering the entire audio frequency band from 20 Hz to 20 KHz and producing high fidelity sound with sufficient sound pressure level, requiring large radiating/moving surfaces and volumes.
Method used
An air-pulse generating device with a flap pair that performs common mode and differential mode movements to create amplitude-modulated ultrasonic air pressure variations, producing air pulses with a synchronous demodulation process to reproduce audible sound signals.
Benefits of technology
The device effectively reproduces audible sound by shifting ultrasonic spectral components to the baseband, achieving high fidelity sound pressure levels with a compact design.
