OEM&ODM 61 Keys Toddler Digital Electronic Keyboard Musical Instrument for Sale

The electric piano is an electroacoustic instrument. It is a kind of instrument used to replace the piano in some occasions, which rose in the 1960s and 1970s and was popular from the 1980s to the early 1990s.

The sound principle of the electric piano is to use the keyboard as the on-off switch to form an electric pulse. Once the key is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a certain frequency waveform, and then it is amplified by the frequency divider and sent to the speaker for sound. The whole sound production process depends on a simple frequency division analog circuit, so the keyboard has no force and string feeling, and the sound is relatively mechanical and monotonous.
