Digital electric pianos generate sound by sampling the sound sources of mechanical pianos, coordinating with the keystroke sensing mechanism, and then emitting the sound through speakers. When playing, the conductive rubber tube beneath the pressed key touches the circuit board, transmitting signals to the sound source chip, which then sends out the corresponding musical notes to the speakers to produce music. Therefore, the key components of an electric piano are the keyboard, circuit board, sound source chip, and speakers, supplemented by accessories such as a switch panel, a three-pedal set, a power supply, and a wooden or plastic PVC housing, which together form a complete electric piano.

Among these components, the keyboard is a crucial part. Currently, keyboards on the market are categorized into graded hammer-action keyboards, also known as weighted hammer-action keyboards, and light-touch keyboards. Light-touch keyboards offer a slightly inferior feel. Standard keyboards typically have 88 keys, including 52 white keys and 36 black keys.

What we are recommending to you now is the universal weighted hammer-action keyboard produced by our company. It features high-grade white plastic glossy keys paired with black matte anti-slip keys, and is equipped with built-in weighted iron hammers. When played, it offers a heavy feel and responsive rebound, achieving a realistic effect similar to that of a mechanical piano.

Our keyboard is compatible with various models of digital electric pianos. If you have a need to build your own electric piano, we can provide you with this standard graded hammer-action keyboard. We offer screw hole location diagrams and cable wiring diagrams corresponding to the keyboard for your production and testing purposes. Please contact us if needed.
