A piezo-electric material is one who's physical dimensions (size) noticeably change when a current is passed through it. So if an AC (alternating current) is passed through a piezo-electric material, it itself alternates, or oscillates. This type of material is exploited in Electron Microscopes and Atomic Force Microscopes, which is how they are able to get such small, yet precise images.
When a mechanical pressure or load is given to optic axis of the piezoelectric crystal, it develops equal and opposite charges on the mechanical axis of the crystal. This is called piezoelectric effect.
Vice versa effect is called inverse piezoelectric effect.
This principle is used in piezoelectric oscillator, where a changing voltage across the crystal causes it to change size, which in turn creates a counter voltage which opposes the voltage and creates a feedback ringing effect when used with an amplifier configured as an oscillator.
The "ringing" frequency of the oscillation is determined by the mechanical dimensions of the crystal, similar to bells, strings, or pipes. Additionally, depending on the design of the oscillator circuit, capacitors, inductors and resistors may be needed to tune the circuit for optimum start-up and operation.
Commonly called crystal oscillators. Quartz material can be cut to vibrate at a very specific frequency. In an amplifier feedback loop it operates at that frequency. Oscillates.

The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.

A transistor is often referred to as an oscillator because of its ability to transfer resistance. it can also switch off and on repeatedly, mimicking an oscillator.
