Determine --- according to the specifications packed with the tweeter --- what frequency range and type of piezo you have. Most direct-diaphragm automotive or small-speaker piezos have a bottom-end ...
This article proposes a design method for a highly sensitive ultrasonic sensor based on piezoelectric bending vibration. First, based on the full-element rectangular thin plate theory, the resonant ...
The driver exploits the fact that, at resonance, current and voltage is in phase for a piezoelectric transducer. By locking the driving signal to the current feedback signal, i.e. adjust the driving ...
USound's Conamara MEMS tweeter is incorporated in the ultrasonic demonstrator. (Photo: Business Wire) USound’s latest MEMS-based Ready-to-Deploy Ultrasonic Module will be showcased at the ...
