A bell box is an audible device, often electric, which when activated, emits a chime, bell, or buzzer sound.
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. [1] 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 strobe or other flashing lights.
A doorbell uses a bell box to signal the occupant of a home or business.
A bell box for early telephones is commonly known as a ringer box. [2]
Other types of bell boxes include alarm clocks, burglar alarms, and smoke alarms.

A telephone is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be easily heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. The term is derived from Greek: τῆλε and φωνή, together meaning distant voice. A common short form of the term is phone, which came into use early in the telephone's history.
An idiophone is any musical instrument that creates sound primarily by the vibration of the instrument itself, without the use of air flow, strings (chordophones), membranes (membranophones) or electricity (electrophones). It is the first of the four main divisions in the original Hornbostel–Sachs system of musical instrument classification. The early classification of Victor-Charles Mahillon called this group of instruments autophones. The most common are struck idiophones, or concussion idiophones, which are made to vibrate by being struck, either directly with a stick or hand or indirectly, with scraping or shaking motions. Various types of bells fall into both categories. A common plucked idiophone is the Jew's harp.
Change ringing is the art of ringing a set of tuned bells in a tightly controlled manner to produce precise variations in their successive striking sequences, known as "changes". This can be by method ringing in which the ringers commit to memory the rules for generating each change, or by call changes, where the ringers are instructed how to generate each change by instructions from a conductor. This creates a form of bell music which cannot be discerned as a conventional melody, but is a series of mathematical sequences.
A ringtone, ring tone or ring is the sound made by a telephone to indicate an incoming call. Originally referring to and made by the electromechanical striking of bells, the term now refers to any sound on any device alerting of a new incoming call—up to and including recordings of original telephone bells.
Campanology is the scientific and musical study of bells. It encompasses the technology of bells – how they are founded, tuned and rung – as well as the history, methods, and traditions of bellringing as an art.
The belfry is a structure enclosing bells for ringing as part of a building, usually as part of a bell tower or steeple. It can also refer to the entire tower or building, particularly in continental Europe for such a tower attached to a city hall or other civic building.
A buzzer or beeper is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Typical uses of buzzers and beepers include alarm devices, timers, train and confirmation of user input such as a mouse click or keystroke.
A bell is a directly struck idiophone percussion instrument. Most bells have the shape of a hollow cup that when struck vibrates in a single strong strike tone, with its sides forming an efficient resonator. The strike may be made by an internal "clapper" or "uvula", an external hammer, or—in small bells—by a small loose sphere enclosed within the body of the bell.
A church bell in Christian architecture is a bell which is rung in a church for a variety of religious purposes, and can be heard outside the building. Traditionally they are used to call worshippers to the church for a communal service, and to announce the fixed times of daily Christian prayer, called the canonical hours, which number seven and are contained in breviaries. They are also rung on special occasions such as a wedding, or a funeral service. In some religious traditions they are used within the liturgy of the church service to signify to people that a particular part of the service has been reached. The ringing of church bells, in the Christian tradition, is also believed to drive out demons.
A handbell is a bell designed to be rung by hand. To ring a handbell, a ringer grasps the bell by its slightly flexible handle – traditionally made of leather, but often now made of plastic – and moves the arm to make the hinged clapper strike the inside of the bell. An individual handbell can be used simply as a signal to catch people's attention or summon them together, but handbells are also often heard in tuned sets.
A doorbell is a signaling device typically placed near a door to a building's entrance. When a visitor presses a button, the bell rings inside the building, alerting the occupant to the presence of the visitor. Although the first doorbells were mechanical, activated by pulling a cord connected to a bell, modern doorbells are electric, operated by a pushbutton switch. Modern doorbells often incorporate intercoms and miniature video cameras to increase security.
An electric bell is a mechanical or electronic bell that functions by means of an electromagnet. When an electric current is applied, it produces a repetitive buzzing, clanging or ringing sound. Electromechanical bells have been widely used at railroad crossings, in telephones, fire and burglar alarms, as school bells, doorbells, and alarms in industrial plants, since the late 1800s, but they are now being widely replaced with electronic sounders. An electric bell consists of one or more electromagnets, made of a coil of insulated wire around an iron bar, which attract an iron strip armature with a clapper.
Russian Orthodox bell ringing has a history starting from the baptism of Rus in 988 and plays an important role in the traditions of the Russian Orthodox Church.
A "ring of bells" is the name bell ringers give to a set of bells hung for English full circle ringing. The term "peal of bells" is often used, though peal also refers to a change ringing performance of more than about 5,000 changes.
This history of the telephone chronicles the development of the electrical telephone, and includes a brief overview of its predecessors. The first telephone patent was granted to Alexander Graham Bell in 1876.
A jingle bell or sleigh bell is a type of bell which produces a distinctive 'jingle' sound, especially in large numbers. They find use in many areas as a percussion instrument, including the classic sleigh bell sound and morris dancing. They are typically used as a cheaper alternative to small 'classic' bells.
A ringer box is a telephone signaling device, similar to a bell box. It usually contains an electromechanical gong and was used with most early desk stand telephones, such as candlestick telephones and the Western Electric type Western Electric hand telephone sets, which were too small to hold a ringer and other required electrical components. Many pay station telephones also used a separate ringer box.
Google Nest is a line of smart home products including smart speakers, smart displays, streaming devices, thermostats, smoke detectors, routers and security systems including smart doorbells, cameras and smart locks.
Veronese bell ringing is a style of ringing church bells that developed around Verona, Italy from the eighteenth century. The bells are rung full circle, being held up by a rope and wheel until a note is required.
