Description
Technical field
The utility model relates to piano field, is specifically related to position, a kind of piano hammerhead hole angle measurement tool.
Background technology
Modern piano, is described as the king of musical instrument in musical instrument.Its broad range is across 7 octaves (A2-c5), and which part musical instrument its exclusive performance, aesthetic value and enrich expressive force, do not have can be by comparison.Modern piano can reflect that works are the most weak to the change of the strongest dynamics, embody multi-level acoustic characteristic, its abundant expressive force can simulate whole large-scale symphony orchestra, music expression diversification more can be made by playing skill process, even connecting various interrupted tone, continuant etc. can be sharp and optionally show, and can give expression to rich colors and artistic conception that melody takes out of truly.
When player's piano, by finger tip contacts key, drive keyboard hammered string instrument system accurately and fast what lever transmission, traction hammerhead knocks string, string is made to produce vibration, and by string code, vibrational energy having been passed to the soundboard of sympathetic response effect, the vibration of soundboard produces the ripple of density in atmosphere, sends the sound of the piano that we hear.
The good tonequality 50% of piano is decided by source of sound, and 25% is hammerhead.Certainly, be difficult by the primary and secondary that any data weigh these factors.But certainly, hammerhead affects one of piano sound very key factor, to arrange with string and soundboard decides the tonequality of piano jointly.The quality of hammerhead, elasticity, to hit string mode and hit the length that string lasts be determine the key of piano sound.
At present, market does not have better testing tool can detect the angle of position, hammerhead hole, the angle of the position, hole of piano hammerhead is difficult to the hitting dynamics ensureing and grasp hammerhead in this case.
In view of this, need to invent position, a kind of piano hammerhead hole angle measurement unit.
Utility model content
The purpose of this utility model is the defect overcoming prior art, position, the piano hammerhead hole angle measurement unit providing a kind of structure simple, easy to operate.
To achieve these goals, the technical scheme taked of the utility model is as follows:
A kind of position, piano hammerhead hole angle measurement tool, it comprises measuring appliance, cramp bar and the stationary installation be arranged on described cramp bar, described cramp bar is provided with connecting hole, center and the described connecting hole of described measuring appliance are hinged by screw, the top of described cramp bar is provided with scale slotted eye, described scale slotted eye and described stationary installation lay respectively at the both sides of described connecting hole, described stationary installation comprises and is arranged on upper fixed block on described cramp bar and lower fixed block, fixed piece is fixedly connected with described lower fixed block, described lower fixed block is or/and fixed piece is provided with the draw-in groove parallel with described cramp bar, dismountable fixing pin rod for fixing piano hammerhead hole is provided with in described draw-in groove.
Further improve as the utility model, described fixed block is provided with the draw-in groove parallel with described cramp bar.
Further improve as the utility model, the top of described cramp bar is provided with " 7 " font top, and described " 7 " font is endured on head and offered scale slotted eye.
Compared with prior art, the beneficial effect acquired by the utility model is as follows:
Position, the piano hammerhead hole angle measurement tool that the utility model provides overcomes deficiency in the past, position, the hole angular values that can meet hammerhead measures requirement, reduce because the incidence of the inadequate or inaccurate factor of contraposition of the hammerhead hitting dynamics that causes is forbidden in the position, hole of piano string mallet, this device possesses that structure is simple, cost is low, measure simple to operate, the feature of intuitive measurement results.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of force measuring machine of the present utility model;
Accompanying drawing 2 is the structural scheme of mechanism of this practical cramp bar;
Accompanying drawing 3 is the fixing pin rod of this practicality and piano hammerhead structural representation;
In the accompanying drawings:
Fixed block, 4 times fixed blocks, 5 draw-in grooves, 6 scale slotted eyes, 7 screws, 8 connecting holes, 9 fixing pin rod, 100 piano hammerheads on 1 measuring appliance, 2 cramp bars, 3.
Embodiment
Below in conjunction with accompanying drawing 1-3, detailed further describing is carried out to the utility model.
As shown in accompanying drawing 1,2 and 3, a kind of position, piano hammerhead hole angle measurement tool, it stationary installation comprising measuring appliance 1, cramp bar 2 and be arranged on described cramp bar 2, described cramp bar 2 is provided with connecting hole 8, center and the described connecting hole 8 of described measuring appliance 1 are hinged by screw 7, the top of described cramp bar 2 is provided with " 7 " font top, and described " 7 " font is endured on head and offered scale slotted eye 6.Described scale slotted eye 6 and described stationary installation lay respectively at the both sides of described connecting hole 8, described stationary installation comprises and is arranged on upper fixed block 3 on described cramp bar 2 and lower fixed block 4, be fixedly connected with described lower fixed block 4 for fixed piece 3, described lower fixed block 3 is provided with the draw-in groove 5 parallel with described cramp bar 2, in described draw-in groove 5, is provided with dismountable fixing pin rod 9 for fixing piano hammerhead hole.
Using method of the present utility model is as follows: as shown in Figure 3, when needs are measured, one end of fixing pin rod 9 is inserted in piano hammerhead hole, then fixing pin rod 9 is snapped in draw-in groove 5, around screw 7 rotary bearing rod 2, make the baseline of the justified margin measuring appliance 1 of the side of the close measuring appliance 1 of piano hammerhead 100, the number of degrees now pointed by scale slot are direct reading, are the angle of measured piano hammerhead 100 mesopore position.
The above embodiment is only preferred embodiment of the present utility model, and is not the exhaustive of the feasible enforcement of the utility model.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the utility model principle and spirit, all should be contemplated as falling with within claims of the present utility model.
