Bell box

A bell box is an audible device, often electric, which when activated, emits a chime, bell, or buzzer sound.

The housing of the bell box may be manufactured from wood, metal, or plastic.

The basic core component of a conventional bell box is an electromagnet and a bell or other metal piece, some of which create a repetitive sound.

The bell box may also include visual alerts such strobe or other flashing lights.

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