Abstract

The utility model relates to an electrical piano or electronic organ and discloses a plastic keyboard improved structure used for the electrical piano or electronic organ. The utility model includes a keyboard base, piano keys arranged above the keyboard base, a piano bracket and a piano balance weight; the lower surfaces of the piano keys are provided with the bottom contact cushion of the keys; the piano bracket is fixed on the keyboard base; and the tail end of the keyboard is hinged with the keyboard bracket; the piano balance weight is arranged below the keyboard base and is opposite to the keyboard; the middle part of the piano balance weight is hinged with the piano bracket; the upper surface of the piano balance weight is provided with a salient which is sheathed with a wear-resistance jacket; and the wear-resistance jacket is butted with the bottom contact cushion of the keys; the lower surface of the bottom contact cushion of the keys is provided with a strip lug; the strip lug transversely extends along the piano keys. When playing the piano keys, the wear-resistance jacket and the bottom contact cushion of the keys generate relative moving and are matched in a friction way, as well as generate a jump when passing through the lug, thereby appearing a broken-connected hand feel to lead the hand feel of the plastic keyboard to be more vivid.

Description

A kind of fender or mellotron plastic key disk improving structure

Technical field

The utility model relates to fender or mellotron, particularly relates to a kind of fender or mellotron plastic key disk improving structure.

Background technology

The emulating plastics keyboard is widely used in fields such as fender and mellotron, owing to advantages such as it is cheap, and are easy to use, is more and more accepted by everybody.But, existing plastics keyboard is that people copy out according to the feel and the characteristics of conventional steel piano key board, though the physical dimension of its appearance is the same substantially with the conventional steel piano key board, but its design feature mainly is the lower surface by contact mat at the bottom of projection on the key counterweight upper surface and the key to relatively move, frictional fit, giving player's sensation like this is level and smooth feel, and does not have the disconnected jointly sense on traditional piano.

The utility model content

Technical problem to be solved in the utility model is that solution fender or mellotron do not have the disconnected jointly problem of sense with plastics keyboard feel.

In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of fender or mellotron plastic key disk improving structure, comprise keyboard base, be arranged on key, key support and the key counterweight of keyboard base top, the lower surface of described key is provided with contact mat at the bottom of the key; The key support is fixed on the keyboard base, and the tail end of key and key support are hinged; The key counterweight is arranged on the below of keyboard base and relative with key, and the middle part and the keyboard base of key counterweight are hinged; The upper surface of key counterweight is provided with the projection of the wear-resisting sheath of suit, and contact mat butt at the bottom of this wear-resisting sheath and the key; The lower surface of contact mat is provided with the strip lug, nib at the bottom of the key, and described strip lug, nib is along the key horizontal expansion.

The xsect of the lug, nib at the bottom of the described key on the contact mat lower surface be semicircle and with contact mat smooth transition at the bottom of the key.

The utility model, when key was played, contact mat produced the frictional fit that relatively moves at the bottom of wear-resisting sheath and the key, moved past protruding the generation once when stupefied and jumped, thereby disconnected jointly sense occurs, made the feel of plastics keyboard more true to nature.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2, Fig. 3 are existing keyboard course of work synoptic diagram;

Fig. 4, Fig. 5 are the utility model course of work synoptic diagram.

Embodiment

Below in conjunction with accompanying drawing the utility model is made detailed explanation.

As shown in Figure 1, the utility model comprises keyboard base 3, is arranged on the key 1 of keyboard base 3 tops, key support 2 and key counterweight 4, and the lower surface of described key 1 is provided with contact mat 7 at the bottom of the key; Key support 2 is fixed on the keyboard base 3, and the tail end of key 1 and key support 2 are hinged; Key counterweight 4 is arranged on the below of keyboard base 3 and relative with key 1, and the middle part and the keyboard base 3 of key counterweight 4 are hinged; The upper surface of key counterweight 4 is provided with the projection 5 of the wear-resisting sheath of suit, and this projection 5 and contact mat 7 butts at the bottom of the key; The lower surface of contact mat 7 is provided with strip lug, nib 6 at the bottom of the key, and described strip lug, nib 6 is along key 1 horizontal expansion.

The xsect of the lug, nib 6 at the bottom of the described key on contact mat 7 lower surfaces be semicircle and with the lower surface smooth transition of contact mat at the bottom of the key 7.

Improvement principle of the present utility model is simple, implements to be easy to, and is applicable to the keyboard of all principles of similitude.As long as existing this frictional fit face in the keyboard just can use, make the feel of plastics keyboard more true to nature after the application, before this, a lot of engineering technical personnel adopt various complex mechanical construction, want to reach the feel of imitation conventional keyboard, some can be realized, but manufacture difficulty is big, the cost height is difficult to realize practical application.

The utility model can be realized large batch of production, and technology is simple, and material requirements is not high yet, is easy to realize on various Simutation keyboards, and the keyboard after the improvement has tangible class to promote.

The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
