Note: The piezo buzzer is polarized, meaning that power must be applied to the correct pins.

Great for use as part of a Code Practice Oscillator or personal alarm notification system. Results Price and other details may vary based on product size and color. Used in manufacturing applications such as laptops, alarms, pagers, etc. This buzzer is ideal when you need to fit a buzzer in a small place. The piezo buzzer is 5V TTL logic compatible and Breadboard friendly long 10cm (4”) connection leads.

Inside is a piezo element plus the driver circuitry that causes it oscillate. Furthermore, the lineup includes piezo actuators, which are the core component in high-precision piezo fuel injection systems in diesel and gas. Unlike a plain piezo, this buzzer does not need an AC signal. Compact and low-power consumption piezoelectric unimorph-type buzzers and receivers can be used in automotive applications that require high levels of sound pressure at relatively broad frequency bands. They have advantages in these applications, not the least of which is simple and solid state construction that resists seawater better than a ribbon or cone based device would.Apply 3V to 4V to this larger sized piezo buzzer module and you'll be rewarded with a loud 3.3KHz BEEEEEEEEEEEEEEEEEP. Piezoelectric speakers can have extended high frequency output, and this is useful in some specialized circumstances for instance, sonar applications in which piezoelectric variants are used as both output devices (generating underwater sound) and as input devices (acting as the sensing components of underwater microphones). This is why they are generally used in applications where volume and high pitch are more important than sound quality. Additionally, their frequency response, in most cases, is inferior to that of other technologies, especially with regards to bass and midrange.

There are also disadvantages: some amplifiers can oscillate when driving capacitive loads like most piezoelectrics, which results in distortion or damage to the amplifier.

Piezoelectric speakers have several advantages over conventional loudspeakers: they are resistant to overloads that would normally destroy most high frequency drivers, and they can be used without a crossover due to their electrical properties.

They are also used for producing ultrasound in sonar systems.

Piezoelectric speakers are frequently used to generate sound in digital quartz watches and other electronic devices, and are sometimes used as tweeters in less-expensive speaker systems, such as computer speakers and portable radios. Typically they operate well in the range of 1-5 kHz and up to 100 kHz in ultrasound applications.

Ĭompared to other speaker designs piezoelectric speakers are relatively easy to drive for example they can be connected directly to TTL outputs, although more complex drivers can give greater sound intensity. The prefix piezo- is Greek for 'press' or 'squeeze'. The initial mechanical motion is created by applying a voltage to a piezoelectric material, and this motion is typically converted into audible sound using diaphragms and resonators. When fixed to a metallic diaphragm and excited with an alternating voltage, the diameter of the disc varies by a small amount, this causes dishing of the diaphragm which gives a much louder sound.Ī piezoelectric speaker (also known as a piezo bender due to its mode of operation, and sometimes colloquially called a " piezo", buzzer, crystal loudspeaker or beep speaker) is a loudspeaker that uses the piezoelectric effect for generating sound. The white ceramic piezoelectric material can be seen fixed to a metal diaphragm.
