Please tell me what each part of the alarm clock is called, what the curved one on top is called, what the two round ones under the curved thing are called, and its

Exterior parts of an alarm clock include the pull ring, the rattle, the pendulum, the case, the clock face, the hands, the struts, and so on.

The so-called specialized designations in engineering are not so fixed, and the exact same thing can be called something completely different on different manufacturers' drawings.

There are many types of alarm clocks, mechanical and quartz, which have become indispensable items in people's lives since they were invented using the principle of the pendulum.

Basic performance

Mechanical alarm clocks are made of a high manganese steel material with a clockwork to store energy; after many levels of gears to increase the angular velocity, note that the tooth shape is not involute, but pendulum, in order to reduce friction, suitable for high efficiency transmission under small torque.

After the reciprocating oscillating escapement, a structure with an inherent vibration period to realize the timing requirements, that is, constant angular velocity; escapement with a hairspring like hairspring hairspring is constant elasticity alloy, is an elastic component, and its mechanical properties are less affected by temperature.

Quartz clocks use quartz crystals to generate the basic oscillation, through the stepper motor to drive the gear set, drive the pointer set.
