its a thing that you use to build a circuit....
A piezo pickup is the type of pickup most commonly used in acoustic-electric instruments. This type of pickup is normally placed in or near the bridge of the instrument thus making it a piezo bridge.
it has a transducer in it, but is not one itself
Transducer
The light for the sheet music or maybe it has a Piezo pickup or something Im not sure though?
They use the piezo electric effect of certain crystals to capture the sound waves and resonance of the instrument.
Electrical energy is converted to sound energy in loudspeakers and earphones. The basic internal transducers are either magnetic coils or piezo-electric crystals.
The main types of transducer guitar pickups are single-coil, humbucker, and piezo. Single-coil pickups produce a bright and clear sound, humbuckers offer a thicker and warmer tone with less noise, and piezo pickups provide a more acoustic-like sound. Each type has its own unique sound qualities and performance characteristics, so the choice depends on personal preference and the desired tone for the music being played.

The basic principle of a transducer: A transducer which converts a physical quantity to the electrical quantity.
the piezo-eletric property of a crystal is the principle of quartz clock

A piezo is just a manual, mechanical type of module. In order to work as an ignition the piezo module will need to be wired to an electrode which will spark when the piezo module is pressed or cranked. An ignition system is an assembly of parts and the piezo is like a spark generator for an ignition that does not use batteries or electricity. Pressing or turning the piezo module will send electricity to the electrode which should be mounted where gas emits from the burner so the electrode sparking will ignite gas as the gas leaves the burner.
what type of transducer potentiometer
Teh varying pressure of the air (the sound) causes a varying electric potential in microphones. There are various techniques, one is called "dynamic microphone" whereby a membrane with a coil is allowed to move inside a magnetic field. The sound moves the membrane, the movement of the coil inside the magnetic field generates a current in the wire which is the signal. Ten kinds of microphone are discussed on Wikipedia (see Related link below)
please give a simple defineatoin of transducer.
