The first electric buzzer was invented in 1831 by Joseph Henry
Henry's invention of the electric buzzer was a significant milestone in the history of electric signaling devices. His buzzer was designed to physically strike a bell using electromagnetism, triggered remotely over a wire. This early device laid the foundation for the development of more advanced audio signaling devices that we use today.
Joseph Henry was born on December 17, 1797, in Albany, New York, and had a keen interest in science and invention from an early age. While working at the Albany Academy in 1829, he made significant improvements to the design of electromagnets, increasing their power by insulating the wire instead of the iron core. This allowed him to wrap a larger number of wire turns around the core, revolutionizing the capabilities of electromagnets.
Henry's expertise in electromagnetism led to several important discoveries and inventions. In 1831, he created one of the first machines to use electromagnetism for motion, which became the earliest ancestor of the modern DC motor. He also invented the electric relay in 1835, which served as the basis for the practical electrical telegraph. Henry's work on electromagnetism and his inventions, including the electric buzzer, paved the way for advancements in electrical signaling and telecommunication.
Beyond his inventions, Joseph Henry held various prestigious positions throughout his career. He served as the first secretary of the Smithsonian Institution and played a pivotal role in the establishment of the U.S. Weather Bureau. Additionally, he was the president of the National Academy of Sciences from 1868 until his death on May 13, 1878. Henry's legacy is honored through various dedications, including the naming of the standard electrical unit of inductive resistance as the "henry" in his honor.

It was designed to physically strike a bell using electromagnetism
The first electric buzzer was invented in 1831 by Joseph Henry, an American scientist. This early device was designed to physically strike a bell using electromagnetism. Specifically, it was designed to ring a bell triggered remotely over a wire. These buzzers were primarily used as doorbells until they were phased out in the early 1930s in favour of musical chimes, which had a softer tone.
The word "buzzer" comes from the rasping noise that these early electromechanical buzzers made. The electric buzzer was based on an electromechanical system identical to an electric bell without the metal gong. The main function of a buzzer is to convert the signal from audio to sound. They are typically powered through DC voltage and used in timers, alarm devices, printers, alarms, computers, etc.
There are two main types of buzzers: active and passive. An active buzzer has a built-in oscillator and can produce sound with only a DC power supply. A passive buzzer, on the other hand, does not have a built-in oscillator and requires an AC audio signal to function. The passive buzzer has an anatomy similar to a loudspeaker, with a circular magnet surrounding an inner wire coil. The disc vibrates due to the magnetic force generated by the electromagnetic coil.
Over time, buzzers have gotten smaller and evolved into various forms. One subtype of the buzzer is the vibrating buzzer, which is placed on the outside instead of the inside. It generates sound through disc movement and magnetism. Piezoelectric buzzers, or "piezo buzzers," were invented by Japanese manufacturers and became popular in the 1970s and 1980s.

It was primarily used as a doorbell
The first electronic buzzer was invented by Joseph Henry in 1831 and was primarily used as a doorbell. The electric doorbell was designed to physically strike a bell using electromagnetism, triggered remotely over a wire. These buzzers were usually anchored to a wall or ceiling to use it as a sounding board. The word "buzzer" comes from the rasping noise that these electromechanical buzzers made.
Over time, buzzers have gotten smaller and evolved into many different forms. They can be categorised into two types: active and passive buzzers. An active buzzer has a built-in oscillator and can produce sound with only a DC power supply. They are simple to use and are typically available in voltages from 1.5V to 24V. A passive buzzer, on the other hand, does not have a built-in oscillator and requires an AC audio signal to function. It has an anatomy similar to a loudspeaker, with a circular magnet surrounding an inner wire coil.
The electric buzzers used as doorbells were phased out in the early 1930s and replaced by musical chimes, which produced a softer tone. However, buzzers continued to find applications in various devices. For example, Japanese manufacturers incorporated piezoelectric buzzers into a wide array of products during the 1970s and 1980s.

Japanese manufacturers invented piezoelectric buzzers in the 1970s and 1980s
The electric doorbell, an audio signalling device, was invented in 1831 by Joseph Henry. However, it was Japanese manufacturers who invented piezoelectric buzzers in the 1970s and 1980s, building on the early electromechanical system.
Piezoelectric buzzers, or piezo buzzers, were fitted into a wide range of products during this period. This was due to the cooperative efforts of Japanese manufacturing companies. In 1951, they established the Barium Titanate Application Research Committee, which allowed companies to be "competitively cooperative" and bring about several piezoelectric innovations and inventions.
Piezoelectric buzzers work by using the piezoelectric effect and pulse current to make a metal plate vibrate and generate sound. They are driven by an oscillating electronic circuit or other audio signal sources, and driven with a piezoelectric audio amplifier.
Piezo buzzers are used in alarm devices, timers, confirmation of user input, and many other applications. They are also used in household devices such as watches, clocks, and keyboards.

The joy buzzer, a practical joke device, was invented in 1928 or 1931
This misconception that the joy buzzer delivers an electric shock is largely due to false advertising by the makers of the device. In reality, it only causes a vibration that simulates a shock. However, some variations were later created to actually deliver a mild electric shock to the person being pranked.
The joy buzzer was an instant success, allowing Adams to expand his company. In 1932, the item received U.S. patent 1,845,735. In 1987, Adams' son, Joseph "Bud" Adams, redesigned the mechanism for greater durability and a louder buzz, marketing it as the Super Joy Buzzer.
The electric doorbell, another type of buzzer, was invented in 1831 by Joseph Henry. It was designed to physically strike a bell using electromagnetism, triggered remotely over a wire. These buzzers were mainly used in early doorbells until they were phased out in the early 1930s in favour of musical chimes with softer tones.

Frequently asked questions
The first electronic buzzer was invented in 1831 by Joseph Henry and was mainly used as a doorbell.
A joy buzzer is a practical joke device that consists of a coiled spring inside a disc worn in the palm of the hand. When the wearer shakes hands with another person, a button on the disc releases the spring, creating a vibration that mimics an electric shock.
The joy buzzer was invented in 1928 by Soren Sorensen Adams of the S.S. Adams Co. It was officially patented in 1932.
