These convert pressure into voltage. When certain crystals are compressed or stretched, they exhibit a voltage across their faces, which can be utilised for various applications. The simplest example is an inexpensive 'crystal' phonocartridge: when the attached stylus vibrates in the grooves of a record, the crystal creates variations in voltage which can be amplified using an amplifier which then produces sound via a loudspeaker.
These crystals also work the other way around, compressing or expanding when voltages are applied across their faces. This is the principle behind, for example, ultrasonic cleaners -high-frequency voltages applied across the crystal results in ultrasonic vibrations.

What is the Resonant frequency of a piezoelectric transducer?
It's peak frequency
What has the author A S DeReggi written?
A. S. DeReggi has written: 'Piezoelectric polymer transducer for dynamic pressure measurements' -- subject(s): Piezoelectric transducers
What does an ultrasound scanner consist of?
the transducer and the data processing unit. The transducer both produces the sound waves that penetrate the body and receives the reflected echoes. Transducers are built around piezoelectric ceramic chips.
Can the energy converted by peizo electric transducers be stored?
Yes. A piezoelectric transducer converts stress (pressure) into electrical energy. You can store electricity in a battery or capacitor.
Why is quartz used in piezoelectric transducer?
Quartz is used in piezoelectric transducers because of potential for high voltage input and acoustic power. Quartz is a piezoelectric crystal and when it is mechanically strained or deformed by stress, electric charges appear on some surfaces. When the strain is reversed, the polarity of the charges reverse. This allows vibration of quartz crystals to be transformed into electric pulses.
What is the basic circuit of transducer?
The question here has been framed wrongly. There is nothing like a general circuit for a transducer. Depending on a transducer you may have many circuits. For eg. a Piezoelectric crystal is a transducer, it can convert both ways; mechanical vibrations to electrical and electrical to mechanical. So you see, there is nothing like a general circuit for a transducer. Another better example would include an Antenna which converts electro-magnetic waves into a electric signal. All that you can say at max is that a transducer is a device that converts one form of energy to another. And that is either due to the virtue of the property of a material or due to a certain circuitry which will vary from transducer to transducer.
How do you pronounce piezoelectric crystal?
Like this: (piezoelectric-crystal)
Why are Earpiece's magnetised?
The simplest form of transducer from an electric signal to sound waves is by way of a small electro-dynamic transducer - really a tiny loudspeaker. But of course any transducer between these energy types can be used. Piezoelectric, capacitance, and so on.Your doctor's stethoscope does not have magnetic earpieces, nor do the earpieces used to communicate with the patient in CT or MRI scans.In the latter case, the metal would seriously interfere with the diagnostic process, and the solution is to have the audio transducer remote, and to connect that to the patients earpiece with plastic tubing. Quite like the speaking tubes on older ships - simple but reliable.
How to generate power from piezoelectricity?
mainly Piezoelectric crystal is a transducer which convert mechanical energy to electrical energy.piezoelectricity material generate power, when we compress or extended its shape.means that when we change in dimension of material then the voltage produced between atoms of material by which power generate.
