These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. However, an electronic keyboard is more specifically a synthesizer with a built-in low-wattage power amplifier and small loudspeakers.
In 1974, Roland Corporation released the EP-30, the first touch-sensitive electronic keyboard.

Casio

Casio Computer Co., LtdCasio ComputerCASIO Computer Co.
Casio and Yamaha are among the leading manufacturers of home keyboards. External storage device: Usually available on professional-grade keyboards and synthesizers, this allows the user to store data in externally connected storage media such as ROM cartridges, floppy disks, memory cards and USB flash drives. Floppy disks and cartridges were obsolete by the early 2000s, with memory cards starting to replace them shortly afterwards. USB storage was originally less common at the time, but was later popularized by Yamaha's lineup of workstation keyboards in 2005 and has become a standard feature ever since. Most keyboards in the 2010s uses USB storage, with the exception of some Casio and Korg models.
Casio's products include watches, calculators, electronic keyboards and other digital music instruments, illuminators, digital cameras (Exilim series), film cameras, cash registers, laptop and sub-notebook computers, mobile phones,PDAs (E-Data Bank), electronic dictionaries, digital diaries (early PDAs), electronic games, computer printers, clocks, and portable televisions.

MIDI

MIDMIDI fileMusical Instrument Digital Interface
Sound generator: A digital sound module, typically contained within an integrated Read-only memory (ROM), which is capable of accepting MIDI commands and producing electronic sounds. Electronic keyboards usually incorporate sample-based synthesis, but more advanced keyboards might sometimes feature physical modeling synthesis.
For example, a MIDI keyboard or other controller might trigger a sound module to generate sound produced by a keyboard amplifier.

Musical keyboard

keyboardkeyboardskeys
Musical keyboard: The white and black piano-style keys which the player presses, thus connecting the switches, which trigger the electronic circuits to generate sound. Most keyboards use a keyboard matrix circuit to reduce the amount of wiring necessary. Electronic keyboards often use unweighted synthesizer-style keys to save costs and reduce the weight of the instrument. In contrast, stage piano and digital pianos typically have weighted or semi-weighted keys, which replicate the feel of an acoustic piano.
Depressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell (carillon), or, on electric and electronic keyboards, completing a circuit (Hammond organ, digital piano, synthesizer).

Keyboard amplifier

Stage pianos, however, typically do not have integrated amplifiers and speakers, as these instruments are normally plugged into a keyboard amplifier in a professional concert setting.
A keyboard amplifier is a powered electronic amplifier and loudspeaker in a wooden speaker cabinet used for amplification of electronic keyboard instruments.

These are commonly used in portable electronic devices, such as digital cameras, mobile phones, laptop computers, tablets, PDAs, portable media players, video game consoles, synthesizers, electronic keyboards, and digital pianos.

Keytar

keyboard guitarclavitarKeyboards
Keytar - A small synthesizer that resembles a guitar which can be played in similar position as an electric guitar: worn on a strap over the shoulders, enabling the performer to move around on a stage. The name is a portmanteau of keyboard and guitar.
The keytar is a relatively lightweight electronic keyboard (with or without a built-in synthesizer) that is supported by a strap around the neck and shoulders, similar to the way a guitar is supported by a strap.

Digital piano

digital pianosweighted keysdigital
These include synthesizers, digital pianos, stage pianos, electronic organs and digital audio workstations. Velocity sensitivity (also found under the keyword touch sensitivity in some manuals): While the least expensive keyboards are simply "on-off" switches, mid-range and higher-range instruments simulate the process of sound generation in chordophones (string instruments) which are sensitive to the speed (or "hardness") of a key press. Mid-range instruments may only have two or three levels of sensitivity (e.g., soft-medium-loud). More expensive models may have a broader range of sensitivity. For implementation, two sensors are installed for each key: the first sensor detects when a key is beginning to be pressed and the other triggers when the key is pressed completely. On some higher-end electronic keyboards or digital pianos, a third sensor is installed. This third sensor allows the player to strike a key and still sound a note even when the key has not yet come to its full resting position, allowing for faster (and more accurate) playing of repeated notes. The time between the two (or three) signals allows a keyboard to determine the velocity with which the key was struck. As the key weight is constant this velocity can be considered as the strength of the press. Based on this value the sound generator produces a correspondingly loud or soft sound. The least sophisticated types of touch sensitivity cause the keyboard to change the volume of the instrument voice. The most sophisticated, expensive types will trigger both a change in volume and a change in timbre, which simulates the way that very hard strikes of a piano or electric piano cause a difference in tone—as well as an increase in volume. Some sophisticated touch-sensitivity systems accomplish this by having several samples of an acoustic instrument note per key (e.g., a soft strike, a mid-level strike, and a hard strike). Alternatively, a similar effect can be accomplished using synthesis-modelling of the ADSR envelope or digital modelling (e.g., for the hard strike, the keyboard would add the timbres associated with a hard strike—in the case of a Fender Rhodes voice, this would be a biting, "bark" sound).
A digital piano is a type of electronic keyboard designed to serve primarily as an alternative to the traditional piano, both in the way it feels to play and in the sound produced.

Audio power amplifier

Most consumer electronics sound products, such as TVs, boom boxes, home cinema sound systems, Casio and Yamaha electronic keyboards, "combo" guitar amps and car stereos have power amplifiers integrated inside the chassis of the main product.

ROM cartridge

External storage device: Usually available on professional-grade keyboards and synthesizers, this allows the user to store data in externally connected storage media such as ROM cartridges, floppy disks, memory cards and USB flash drives. Floppy disks and cartridges were obsolete by the early 2000s, with memory cards starting to replace them shortly afterwards.

Most keyboards in the 2010s uses USB storage, with the exception of some Casio and Korg models.
Besides their prominent usage on video game consoles, ROM cartridges have also been used on a small number of electronic musical instruments, particularly electronic keyboards.

The clavichord and some electronic keyboards also respond to the amount of force applied after initial impact—they are pressure-sensitive. This can be used by a skilled clavichord player to slightly correct the intonation of the notes when playing on a clavichord, and/or to play with a form of vibrato known as bebung.

Music stand

Music stand: A metal or plastic rack for holding sheet music or music books upright. The music stand is usually removable to facilitate storage and transportation.
Upright pianos, grand pianos, stage pianos, harpsichords, pipe organs, Hammond organs and many post-1980s electronic keyboards have some type of rack or stand to hold sheet music and/or scores.

Rhythm section

rhythmrhythm instrumentsrhythm instrument
Accompaniment backing tracks: Pre-programmed musical accompaniment tracks (also called rhythm pattern or rhythm style by some manufacturers), consist of a variety of genres for the player to use (e.g., pop, rock, jazz, country, reggae). The keyboard plays a chord voicing and rhythm which is appropriate for the selected genre. In general, programmed backing tracks usually imitate the sound of a rhythm section or an ensemble. Certain keyboards may include a feature that allows the performer to create, compose and customize their own accompaniments. This feature is usually called a pattern sequencer, rhythm composer, or a style creator.
In organ trios, the lower octaves of a Hammond organ or electronic keyboard are used as a substitute for bass guitar or double bass.
