What’s more: Their low power consumption makes them ideal for many battery-operated devices. Thanks to both the reliability and flexibility of piezoelectric vibration plates to produce audible signals - ranging from monotone buzzes and alarms to multi-tones and melodies - their applications in small, high-density assemblies are wide-ranging. And although piezo buzzers require a larger footprint than magnetic buzzers, they produce a higher sound pressure level.
In addition, magnetic buzzers have a higher power consumption of 30 to 100 milliamperes, while piezo buzzers normally consume less than 30 milliamperes - even at higher rate frequencies. Unlike magnetic buzzers that have a narrow operating voltage of somewhere between one and 16 volts, piezo buzzers can typically operate anywhere between three and 250 volts. As a result, it produces an audible sound. So when certain piezoelectric materials are subjected to an alternating field of electricity, the piezo buzzer element - often a manmade piezoceramic material - stretches and compresses in sequence with the frequency of the current. They found that electricity could be generated when a mechanical pressure was applied to particular materials - and the inverse was true as well. The use of the piezo ceramic buzzer was discovered thanks to an inversion of the piezoelectricity principle that was discovered by Jacques and Pierre Curie back in 1880.

Contact APC Today How to Use Piezoelectric Buzzers In addition, thanks to our state-of-the-art production facility, our delivery times are some of the fastest in the industry. Plus, since they can be mounted on circuit boards, they’re highly useful in a wide range of applications and assemblies.ĭespite different construction methods that affect the cost of piezo buzzers, all of our prices are highly competitive. Regardless of the model you choose, our piezo buzzers offer high sound outputs. Yet at the same time, depending on the piezo ceramic buzzer specifications, it’s also reliable and can be constructed in a wide range of sizes that work across varying frequencies to produce different sound outputs.įor instance, at APC International, Ltd., we offer piezo buzzers without signal generators, self-oscillating buzzers that have signal generators and even multi-tone sound generators - often used in alarms and sirens. It’s lightweight with a simple construction, and it’s typically a low-cost product.
In simplest terms, a piezo buzzer is a type of electronic device that’s used to produce a tone, alarm or sound. ^^ Excluding tabs 27.5 ☐.5 w/ tabs (center to center) What Is A Piezo Buzzer? *** 4.0 kHz / 10 cm / 12 Vp-p square wave Rated Voltage: 12 VDC (KPT-1410: 12 Vp-p square wave) Values to be Determined by Customer and APC International
