79x18x1.55mm Piezo Ceramic Generator Bimorph

Piezoelectric ceramics is a kind of information functional ceramic material that can convert mechanical energy and electrical energy to each other. This is called piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties, elasticity, etc., and have been widely used in medical imaging, Acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezo ceramics are mainly used to manufacture ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic discriminators, high-voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices.

Why Choose Our Piezo Buzzer

Piezo buzzers has been more and more popularily used as there is no magnetic field and no coil inside. Typically, piezo buzzers consume less current (less than 30mA), have a broader frequency range (2-6kHz) and wider operating voltage (3- 250V), and generate a higher SPL.

Kailitech piezo buzzers include types of taping, SMD, ultra-low frequency, high SPL, waterproof, high temperature and pressure resistant, with diameter or length and width fm 9.0mm to 100mm, height fm 1.8mm to 65mm, with resonant frequency range fm 200Hz to 15kHz and SPL range fm 65dB to 120dB. Housing material can be ABS, PBT, PPO, LCP, etc.

The main characteristics of Piezo Buzzers are >>

Smaller size, lighter weight, suitable for installation on various circuit boards.

High electric – acoustic power conversion efficiency (above 75%) .

Low power consumption, P≤3V*10mA=0.03W.

High reliability, long durability. The performance and degradation is the log relationship, and the degradation of performance is less than about 5% in 30 years.

No magnetic field, no coil, no electromagnetic interference.
