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 metal part that creates a repetitive sound. The bell sound is normally created inside the box, although the unit may have bells mounted on the outside of the box. The bell box may also include visual alerts such as blinking lights or strobe lights.
An electronic doorbell uses a bell box to signal the occupant of a home or business.
