The Principle Of The Clock

Clocks have a wide range of applications and many varieties, which can be classified according to the principle of vibration, structure and use characteristics. According to the principle of vibration, it can be divided into clocks and watches that use mechanical vibration with low frequency, such as pendulum clocks, balance clocks, etc., clocks and watches that use electromagnetic oscillation and quartz oscillation with high frequency, such as synchronous electric clocks, quartz clocks, etc., according to the structural characteristics, they can be divided into mechanical watches, such as mechanical alarm clocks, automatic, calendars, double calendars, spring and other mechanical watches, electromechanical ones, such as electric pendulum clocks, electric balance wheel clocks, etc., electronic clocks, such as balance wheel electronic clocks, tuning fork electronic clocks, analog and digital display quartz electronic clocks, etc.
