Technical Field

The invention discloses a double-row key electronic organ with a vibration reduction function, and belongs to the technical field of double-row electronic organs.

Background

The double-row key electronic organ is a double-row key, and the common name of the electronic organ with the name learned is derived from the organ. The double-row key electronic organ has similar playing mode to that of pipe organ, has thousands of timbres, has tone quality similar to that of real musical instrument, and may be used in editing timbres according to music requirement, such as strength of sound head, speed and amplitude of string kneading, and has several superposed different timbres. The effect of a band can be played, and the shape of the music is magnificent.

Common double electronic organ is when playing, and foot keyboard is when stepping on, because user's foot strength is big, and is wayward, strikes the bottom plate easily, and it is great to cause the impact sound, has influenced the effect of exercise, reduces its life, and in addition, when foot keyboard tramples many times in succession, causes keyboard exercise frame and ground to produce vibration or resonance very easily, influences the stability and the tone quality effect of tone quality and keyboard exercise frame.

Disclosure of Invention

In order to overcome the defects of the prior art, the double-row key electronic organ foot keyboard exercise rack with the shock absorption function is provided.

The invention is realized by the following technical scheme: the invention provides a double-row key electronic organ with a vibration reduction function, which comprises a frame body, a hand keyboard, a foot keyboard frame, a bottom plate, an electric control system and a vibration reduction soft cushion, wherein the foot keyboard is arranged on one side wall of the foot keyboard frame, a semitone key of the foot keyboard is a short key, a total tone key of the foot keyboard is a long key, the foot keyboard frame is integrally fixed on the bottom plate, the bottom plate and the frame body are fixed into a whole, the vibration reduction soft cushion is fixed on the upper surface of the bottom plate and is positioned right below the short key and the long key,

a plurality of asymmetrically arranged counterweight strips are arranged in the vibration reduction cushion or on the upper surface of the vibration reduction cushion, and the counterweight strips are not overlapped with the vertical position of the long key.

In a further preferred scheme, supporting legs are arranged below the suspended ends of the short keys and the long keys, and damping pads are arranged at the bottoms of the supporting legs.

In a further preferred scheme, the counterweight strip is fixed with the vibration reduction cushion and the bottom plate through either adsorption, sewing, plastic package or a screw connection mode.

In a further preferred scheme, the short keys and the long keys are both fixed with LED indicating lamp belts through clamping grooves.

In a further preferable scheme, the downward inclination angle of the bottom plate is 5-30 degrees.

Compared with the prior art, the invention has the following beneficial effects:

1. in order to solve the problem that the impact sound of the tube keys and the stand of the foot keyboard of the existing double-row electronic organ is larger, and the exercise and use effects are influenced, the invention can reduce the noise interference and improve the exercise and playing effects when long keys and short keys are struck through the vibration reduction cushion; further be provided with a plurality of asymmetrically arranged's counter weight strip in damping cushion inside or upper surface, can effectually avoid again because long key and short key striking bottom plate arouse the vibrations or the resonance of bottom plate, do not coincide the vertical position of counter weight strip and long key simultaneously, avoid long key down when down with counter weight strip collision.

2. LED indicating lamp belts are fixed on the short keys and the long keys through the clamping grooves, and the LED indicating lamp belts are indicators of key positions, so that beginners can learn the key positions conveniently.

3. The below of the free end of short key and long key is provided with the supporting leg, and the bottom of supporting leg is provided with the damping pad, and the user hits long key and short key with the pedal when beating, because shank strength is big, and is wayward, causes hard too much easily, because long key and short key adopt lever structure, and one end hard too much, is likely to step on the foot keyboard, sets up the emergence that the supporting leg can effectively avoid this kind of accident. The bottom of supporting leg is provided with the damping pad and can further eliminates the impact sound after trampling, and the effectual vibrations or the resonance of avoiding arousing the bottom plate because long key and short key striking bottom plate, the user can play and practise with ease.
