When an electric charge is sent through the crystal it changes shape very slightly and creates a very slight sound.
Digital clocks are not a lot different than analog clocks except that they handle the basic time keeping functions using all electronic components instead of mechanically.
A digital clock is a type of clock that displays the time digitally i e.
Digital clocks are often associated with electronic drives but the digital description refers only to the display not to the drive mechanism.

For any clock to work it requires an oscillator.
A source of power to run the clock in a pendulum clock the weights or the springs handle this role.
At the heart of the clock there is a piece that can generate an accurate 60 hertz hz oscillations per second signal.
For instance digital clocks use an electronic power supply either ac power from an outlet in the wall or from a battery.
