Description
Technical Field
The utility model relates to a musical instrument technical field, in particular to electronic piano with resonance musical instrument shell sound production system.
Background
An electronic piano (electronic piano, an electric musical instrument) is a musical instrument that is popular in the early eighties to ninety years since the rise in the sixties to the twentieth century, and is used in place of a piano in some occasions.
The sound production principle of the electric piano is that a keyboard is used as an on-off switch to form electrophoresis, once a key is pressed down, an internal crystal oscillator starts to work to form a pulse to generate a waveform with a certain frequency, and then the waveform is amplified by a frequency divider and sent to a loudspeaker to produce sound. The whole sounding process depends on a simple frequency division analog circuit, so the keyboard has no dynamics and string hitting feeling, and the sound is mechanical and monotonous. Moreover, the existing electronic piano sold by the market adopts an electric cone full-frequency horn to restore the piano sound, and the sound is emitted directionally, so that the piano is not like a real piano.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides an electronic piano with resonance musical instrument shell sound production system solves current electronic piano tone quality and real piano and has the problem of difference.
(II) technical scheme
In order to solve the technical problem, the utility model provides a technical scheme does:
the utility model provides an electronic piano with resonance musical instrument shell sound production system, which comprises a housin, the front portion of casing is equipped with keyboard region, keyboard region is equipped with a plurality of keys, the key is connected with key touch key response circuit board, key touch key response circuit board is connected with keyboard signal processor, keyboard signal processor is connected with the audio processing module of controller, audio processing module is connected with the speaker;
the housing has a surface extending from a front toward a rear of the housing, the surface of the housing being provided with a resonant horn connected in parallel with the speaker.
Wherein, preferably, the loudspeaker is arranged on the surface of the shell.
Preferably, the number of the resonance horns is two, and the two resonance horns are respectively arranged on two sides of the loudspeaker.
(III) advantageous effects
The technical scheme provided by the utility model, compared with prior art, following beneficial effect has:
the utility model discloses be equipped with resonance loudspeaker on the musical instrument shell, through resonance loudspeaker resonance vibration piano casing sound production, the musical instrument sound is three-dimensional dispersibility and sends, has restoreed the tone quality sound field of true piano to the at utmost.
