The piezo disc is a low cost, low power consumption solution for creating good sound output at specific mid and high range frequencies. Future directions include actuators and even piezo speakers. The BeStar piezo element provides performance in both sonic and ultrasonic applications and has found uses in applications beyond piezo buzzers for ultrasonic atomization, or as an impulser. By doping the PZT material, its piezoelectric characteristics can be modified: especially the hardness or softness of the material. This element is designed so that the mechanical resonant frequency matches the frequency of the driving signal. PZT ceramic material is used as the piezoelectric element. The metal diaphragm is usually brass, stainless steel or nickel alloy, thickness less than 0.5 mm. This causes the piezo diaphragms to bend, producing sound waves. When AC voltage is applied across the electrodes of the piezoelectric ceramic it expands and contracts at the frequency applied. The basic element in all of these is a piezoelectric ceramic mounted on a metal diaphragm. Specially formulated piezo ceramic discs are applied to a variety of base disc materials in order to suit most applications. BeStar has special expertise in piezo element production from very small units for sensors, to very large units for sirens. Also called Piezo Diaphragms and Piezo Benders, essentially it is offered so that product manufacturers can produce sound within their own housing/enclosure designs.
