A piezo tweeter contains a piezoelectric crystal coupled to a
mechanical diaphragm. An audio signal is applied to the crystal,
which responds by flexing in proportion to the voltage applied
across the crystal's surfaces, thus converting electrical energy
into mechanical. The conversion of electrical pulses to mechanical
vibrations and the conversion of returned mechanical vibrations
back into electrical energy is the basis for ultrasonic testing.
The active element is the heart of the transducer as it converts
the electrical energy to acoustic energy, and vice versa. The
active element is basically a piece of polarized material (i.e.
some parts of the molecule are positively charged, while other
parts of the molecule are negatively charged) with electrodes
attached to two of its opposite faces. When an electric field is
applied across the material, the polarized molecules will align
themselves with the electric field, resulting in induced dipoles
within the molecular or crystal structure of the material. This
alignment of molecules will cause the material to change
dimensions. This phenomenon is known as the piezoelectric effect.
