The piezoelectric transducers work on the principle of piezoelectric effect. A pickup is a transducer that captures or senses mechanical vibrations produced by musical instruments, particularly stringed instruments such as the electric guitar, and converts these to an electrical signal that is amplified using an instrument amplifier to produce musical sounds through a loudspeaker in a speaker enclosure. This is a marked shift from capacitive MEMS microphones because piezoelectric microphones operate upon a completely different physical phenomenon – the direct conversion of mechanical sound energy into electrical energy. 13. 19. A piezoelectric transducer can be bonded to a solid or immersed in a non-conducting liquid so as to pick up sound signals in any of these carriers. ” (John Wiley & Sons, 2001 Lead zirconate titanate (PZT) based piezoelectric materials are well known for their excellent piezoelectric properties.
