2. Quartz oscillator
The mechanical vibrations of a solid body can be used as a frequency source or standard.
Let's take the example of a tuning fork: a musician's frequency standard. When the tuning fork is excited by a light tap, its two arms start to vibrate. The note it then emits is very pure (single vibration frequency).
The frequency of vibration depends on the material and geometry of the tuning fork. Although the note emitted remains audible for a long time, it is necessary to repeat the excitation after a certain period of time.
A quartz resonator is also an acoustic resonator: it is the seat of a mechanical vibration. It has the advantage of being electrically excited, thanks to the phenomenon of piezoelectricity.
