    Manufacturers of electronic keyboards, synthesizers, and digital pianos have used various designs to recreate the feel of an acoustic piano. The simplest electronic keyboards, sometimes known as synth-action, use springs to restore each key to its resting position, similar in concept to a computer keyboard, but providing the least realism.

    Pressing 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 , or activating an electronic circuit (synthesizer, digital piano, electronic keyboard).

  8. Digital piano - Wikipedia

    en.wikipedia.org/wiki/Digital_piano

    Similar to a traditional acoustic piano, the defining feature of a digital piano is a musical keyboard with 88 keys. The keys are weighted to simulate the action of an acoustic piano and are velocity-sensitive so that the volume and timbre of a played note depends on how hard the key is pressed.
