Electronic keyboard is a kind of keyboard musical instrument, generally there are two kinds, namely stand-up electronic keyboard and portable electronic keyboard. The sound output of the electronic keyboard is generated by the electronic components and amplified by the electronic signal of the audio, and the sound is emitted through the earphone or speaker. Internal components include keyboards, sound generators, rhythm and chord generators, amplifiers and loudspeakers, man-machine interface software, and some have memory, MIDI, etc. The more famous manufacturing plants include Casio, Alesis, Yamaha and Roland.
Electric piano (Electronical piano) is a kind of electro-acoustic musical instrument. It is a musical instrument that emerged in the 1960s and 1970s and was popular in the 1980s to the early 1990s and used to replace the piano in certain occasions. The sounding principle is to use the keyboard as an on-off switch. Once the key is pressed, the internal crystal oscillator starts to work to produce a certain frequency waveform, which is then amplified by the frequency divider and sent to the speaker to sound. The entire sounding process relies on a simple frequency division analog circuit, so the keyboard does not have the strength and feel of the string, and the sound is relatively mechanically monotonous. In contrast, with the development of large-scale integrated circuits and the maturity of digital technology, the Digital Piano appeared.
The digital piano is an electronic musical instrument, usually used as a substitute for the piano. Some digital pianos are also made to look like traditional pianos. It's different from an electronic keyboard. The digital piano is used for some classical and popular music performances. Most of the digital pianos are sounded by a built-in electronic sound source, and a small number of digital pianos use a mechanical device to generate a sound source, which is then converted into a digital signal by electronic components.
Some people say that the digital piano is like a digital camera, and the traditional piano is like an optical camera. I very much agree with this statement. If we think that the traditional piano is the real piano, it can afford it economically, and have confidence in children's learning, buying a piano is of course a good choice; if we feel that we need to reduce investment risks and like the entertainment of digital pianos , You can also consider buying a digital piano . Of course, if we want to use the digital piano as a piano, no matter what brand we choose, we must choose a "heavy cone" function. Don't forget this.
