Abstract

The utility model relates to a novel electric piano which is a combination of a mechanical piano interlinking device and an electric piano electric circuit. The interlinking device comprises keyboards and an interlinking rod, wherein, the electric piano electric circuit comprises an optoelectronic coupler, and tone quality memorizer data reading and control circuit boards corresponding to all keyboards, the optoelectronic coupler fixed on the circuit board is communicated with the circuit board through the interlinking of the keyboards and the string excitation machine, and the circuit board is positioned in the clearance of an linkage system.

Description

Novel fender

Affiliated technical field

The utility model relates to a kind of novel fender that uses photoelectrical coupler, specifically, relates to a kind of novel fender that is combined by mechanical piano linkage and the fender circuit that has adopted photoelectrical coupler.

Background technology

From big aspect, piano comprises two kinds of mechanical piano and fenders.Mechanical piano is by the interlock of keyboard by the hammered string instrument system, and the percussion hammerhead knocks string, can produce the dynamics sense of finger touching, but its qin body is heavy, is not easy to carry; Fender is that the pronouncing frequency of each sound that will get off from the mechanical piano up-sampling is stored in the tone color storer, the player presses key and has just driven corresponding pronouncing frequency, by reading with control circuit sound playing is come out, produce the effect and the characteristics of electroacoustic techniques, the dynamics sense of touching when still but not having mechanical piano to play.The digital piano that has, though with mechanical piano and fender combination, because employing is conductive rubber switch, the accuracy that occurs the corresponding installation with keyboard of conductive rubber switch easily is relatively poor, sound control effect instability, after service cost problem of higher.

Summary of the invention

The purpose of this utility model is to provide a kind of mechanical piano finger velocity sense effect that both had, and can guarantee the novel fender of fender sounding effect again.

The scheme that the utility model solves its technical matters is: design a kind of novel fender, it is the combination of mechanical piano linkage and fender circuit, linkage comprises key, gangbar, the circuit board that circuit comprises photoelectrical coupler, reads and control with the corresponding tone color memory data of each key, the interlock of photoelectrical coupler by key, gangbar of being fixed on the circuit board is connected with circuit board, and circuit board is arranged in the gap of linked system.

Principle of the present utility model: when the finger presses key, device is hit in drive interlock push rod, gangbar, gangbar pedestal, push rod pedestal, push rod, commentaries on classics, hammerhead produces interlock, reaches the dynamics sense effect of the finger touching of mechanical piano.Simultaneously, interlock makes photoelectrical coupler be subjected to the external force effect of key or gangbar to be communicated with the circuit board that reads and control with the corresponding tone color memory data of each key, produces the corresponding tone color of key with finger presses.

The beneficial effects of the utility model are, when having used mechanical piano linkage and fender circuit, have also adopted photoelectrical coupler, make the dynamics of the playing sense that the utlity model has mechanical piano, and the control of fender sound effect is guaranteed.
