■ Product Description
By using the inverse piezoelectric effect of piezoelectric ceramics, a sinusoidal audio amplification signal is input to the "laminated piezo ceramic plate". The "laminated piezo ceramic plate" will bend up and down with the frequency of the amplified audio signal and transmit it to the "vibration substrate" (resin film), which is converted into mechanical energy and drives the air flow to produce sound through plane deformation vibration.
■ Product Features:
①. Ultra slim : thickness ＜0.8mm
②. Low power consumption: 0.3w(1.8KHz/5Vrms);
③. Operating voltage 3.5V～7V (rms)
④. High-quality sound and sound pressure level (SPL)
⑤. No magnetic interference, saving antimagnetic cost
⑥. Easy assembling on Ultrabook/Mobile/Digital Camera/3C products, etc…

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.
