What are the different parts of a digital piano?
Digital piano systems consist of electronic sensors that detect the velocity of key strikes. When a key is pressed, the sensors detect the key’s velocity, and a microchip produces the note with corresponding loudness (the harder you hit the keys, the louder the sound becomes), just like an acoustic piano. A digitized sound bank provides all the sounds, an internal amplifier provides the power, speakers provide realistic reproduction and stereo separation, and headphone jacks provide privacy when practicing. And just like an acoustic piano, digital pianos have sustain pedals (either built-in or as a plug-in option) When the sustain pedal is engaged, all piano keys played will decay gradually after they are released, as if you were holding them down.
