Double Ceramic Piezo Element
The double ceramic piezo element is a piezo element adhered to the top side and bottom side of a metal plate, thus increasing the sound pressure level and resonance frequency. Combined with different cones or housing, it can produce ultra-high sound pressure level and ultra-high frequency sound. Hence, it uses in products such as piezoelectric horns or ultrasonic speakers.
