Abstract
The utility model discloses an upright piano modified system sound shelves, including system sound lead screw, system sound shelves, aluminium system sound shelves, support, system sound head and make the tuning rod, connect through system sound lead screw between system sound head and the system tuning rod, the right side fixed mounting aluminium system sound shelves of support lower extreme, the right side zonulae occludens of aluminium system sound shelves has system sound shelves. This upright piano modified system sound shelves adopts aluminium alloy material's system sound shelves, has improved traditional problem of utilizing the yielding distortion of angle block system sound shelves for aluminium system sound shelves will be made sound shelves pressure through system sound spring and on the string, prevent the string pronunciation, simple structure, and practicality is good, prevents string pronunciation ability reinforce, does not have the effect of echo.
Description
Technical field
The utility model relates to component of musical instrument apparatus field, is specially the sound shelves processed that a kind of upright piano improves.
Background technology
String is the source of sound of all stringed musical instruments, and namely sound does not adjust string on time, makes to reach standard pitch.The commercial designations of string is piano wire, is be specially the special steel wire that musical instrument produces and manufacture.These are different in size, the sounding body being arranged in piano that the different string of diameter, tension force is orderly, i.e. allow, and namely the formation core of allow is be made up of the string of different length, different-diameter and tension force.String on piano, has been divided five sections when fixing, and wherein the 3rd section is effectual chord length, the vibration that namely this section sends be delivered to soundboard and hear by us.Other one, two, four, five section of chord length all belongs to invalid chord length, and vibration is not passed to soundboard.The principle of dual harmonic series is then settle a metal acoustic resonance device in the 5th section of invalid chord length, excites the vibration of this section of string, thus sends abundant overtone.A lot of people says that the high pitch of Shi Tanwei has the sensation of kind of metallic sound, and Here it is has the effect that abundant overtone produces.
And the damper of piano striking machine, most of part is all contained on sound shelves processed, is the vitals producing good tonequality, and sound shelves processed in the market all adopt angle block material, and its angle block is yielding, distortion.For this reason, we provide a kind of sound shelves processed, adopt the sound shelves processed of aluminum alloy materials, improve the problem of the yielding distortion of angle block sound shelves.
Utility model content
This practical purpose is to overcome the shortcoming existed in prior art, the sound shelves processed providing a kind of upright piano to improve, and adopts the sound shelves processed of aluminum alloy materials, to solve in above-mentioned background technology the problem proposing the yielding distortion of angle block sound shelves.
For achieving the above object, the utility model provides following technical scheme: the sound shelves processed that a kind of upright piano improves, comprise sound screw mandrel processed, sound shelves processed, aluminum sound shelves, support, damper head and sound-making bar, by sound screw mandrel processed connection between described damper head and sound-making bar; The right side fixed installation aluminum sound shelves of described pedestal lower end, the right side compact siro spinning technology of aluminum sound shelves has sound shelves processed.
Preferably, described aluminum sound shelves adopt aluminum alloy materials to make.
Preferably, described aluminum sound shelves are provided with sound spring processed with the junction of sound shelves processed, and sound spring handle sound shelves processed are pressed on string, prevent string pronunciation.
Compared with prior art, the beneficial effects of the utility model are: the sound shelves processed that this upright piano improves, adopt the sound shelves processed of aluminum alloy materials, improve traditional problem utilizing the yielding distortion of angle block sound shelves, make aluminum sound shelves be pressed on string by sound spring processed by sound shelves processed, prevent string pronunciation, structure is simple, Practical Performance is good, prevents string articulation ability strong, does not have the effect of echo.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1 sound screw mandrel processed, 2 sound shelves processed, 3 aluminum sound shelves, 4 supports, 5 damper heads and 6 sound-making bars.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
