Components

The housing for the bell box can be made of wood, metal, and/or plastic. The basic core component of a conventional bell box is an electromagnet and a bell or piece of metal that will make a vibrating sound.[1] The bell sound is normally created inside the box, although sometimes there will be one or more bells mounted on the outside of the box. The bell box may also include visual alerts such as blinking lights or strobe lights.

Types of bell boxes

An electronic doorbell uses a bell box to signal the occupant of a home or business.

A bell box for the early versions of the telephone is commonly known as a ringer box.[2]

Other types of bell boxes include alarm clocks, burglar alarms, and smoke alarms.
