Even if you do that, you’ll still receive account-related emails (such as order status notifications, password reset emails, and more). It's actually a thin round piezoelectric 'bender' element bonded to a metal backing that distorts in an 'oilcan' mode when voltage is applied (image from here ).

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'. Less current consumption needed in the leads to the speaker. 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. Piezoceramic speakers feature a low weight and low energy consumption relative to their. 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.
