Abstract
The invention discloses a piano damper head structure. The piano damper head structure comprises piano strings and a damper head, a felt sheet is fixed on the damper head, an additional felt sheet is arranged above the damper head, an additional rod is fixedly connected between the damper head and the additional felt sheet, the felt sheet is of a triangular prism structure, one edge corner of the felt sheet is embedded between two adjacent piano strings, the additional rod is of a telescopic structure, and the additional rod comprises a first section rod body fixedly connected with the damper head and a second section rod body fixedly connected with the additional felt sheet. According to the piano damper head structure, the additional rod with the length capable of being adjusted in a telescopic mode and the additional felt sheet are designed and used for the damper head structure of a first damper in an alto zone, the length of the damper head can be adjusted and increased, the situations that sound damping is not achieved thoroughly and lingering sound is generated are avoided, and the structure is simple.
Description
Technical field:
The present invention relates to piano damper technical field, particularly to a kind of piano damper header structure.
Background technology:
Damper is the vitals of piano, and damper includes damper bar, sound iron wire processed and damper spring, and sound iron wire processed is plugged in the head of damper bar, the head of sound iron wire processed connects damper head, being fixed with felt on damper head, felt and string are close to, and are used for stoping string to shake.Particularity due to piano string row design, on piano, the damper of middle register and bass area tilts arrangement in the opposite direction, in order to avoid when installing, the damper of middle register and bass area collides, therefore on the first damper of middle register, degree size is the shortest during design, so that the audio processed fruit of middle register the first damper is declined to a great extent, during sound processed, sound is not thorough, produces noise during piano playing.
Summary of the invention:
The invention provides a kind of piano damper header structure, solve sound processed in prior art not thorough, the problem producing noise.
The technology solution of the present invention is as follows: a kind of piano damper header structure, it includes piano string, damper head, described damper head is fixed with felt, described damper head is arranged over adding felt, it is fixedly connected with addition rod between described damper head and additional felt, described felt is triangular prism structure, one corner angle of described felt are embedded between two adjacent piano strings, described addition rod is stretching structure, and described addition rod includes to be fixed the first pole being connected and fixes, with additional felt, the second pole being connected with damper head.
As preferably, described damper head is connected with sound-making bar, is fixedly connected with sound iron wire processed, described sound-making bar is hinged with damper pedestal, is fixedly connected with damper spring between described sound-making bar and damper pedestal between described damper head and sound-making bar.
As preferably, on described additional felt, the side towards piano string forms circular groove, and described piano string is embedded in circular groove.So during sound processed, additional felt is close to string, effectively stops string vibrations.
As preferably, additional felt center position is fixed in described addition rod upper end.So make adnexa felt mounting structure stable, it is ensured that audio processed fruit.
As preferably, damper head center position is fixed in described addition rod lower end.So make damper head mounting structure stable, it is ensured that audio processed fruit.
As preferably, described second pole lower end sleeve is in the first pole, and described second pole lower end is provided with semicircle ball and spring, and described first pole upper end forms inward flange.When, after the second pole pull-out, the semi-round ball being positioned at the second pole lower end is ejected by spring, thus preventing the second pole from sliding and deviating from from the first pole upper end.
The beneficial effects of the present invention is: design the accessory shank of telescopically adjustable length and additional felt, for the damper header structure of middle register the first damper, scalable increases damper head length, it is to avoid sound processed is thorough and the generation of lingering sound, simple in construction.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
In figure: 1, piano string；2, damper head；3, felt；4, addition rod；5, additional felt；6, the first pole；7, the second pole.
Detailed description of the invention:
In conjunction with accompanying drawing 1 to one piano damper header structure of the present invention, it is described further.
A kind of piano damper header structure of the present invention, it includes piano string 1, damper head 2, damper head 2 is fixed with felt 3, damper head 2 is arranged over adding felt 5, it is fixedly connected with addition rod 4 between damper head 2 and additional felt 5, felt 3 is triangular prism structure, one corner angle of felt 3 are embedded between two adjacent piano strings 1, addition rod 4 is stretching structure, and addition rod 4 includes with fixing the first pole 6 being connected of damper head 2 and fixes, with additional felt 5, the second pole 7 being connected.
Further, damper head 2 is connected with sound-making bar, is fixedly connected with sound iron wire processed between damper head 2 and sound-making bar, sound-making bar is hinged with damper pedestal, is fixedly connected with damper spring between sound-making bar and damper pedestal.
Further, on additional felt 5, the side towards piano string 1 forms circular groove, and piano string 1 is embedded in circular groove.
Further, additional felt 5 center position is fixed in addition rod 4 upper end.
Further, damper head 2 center position is fixed in addition rod 4 lower end.
Further, the second pole 7 lower end sleeve is in the first pole 6, and the second pole 7 lower end is provided with semicircle ball and spring, and the first pole 6 upper end forms inward flange.
The operation principle of the present invention is: during piano, after key is pressed, and key lever postbrachium is raised above, clutch hammer butt is driven to rotate around axonometer, promote sound-making bar, make the felt 3 on damper head 2 and additional felt 5 depart from piano string 1, piano string 1 can be made to shake sounding；After unclamping key, under damper spring effect, the felt 35 on damper head 2 and additional felt are close to piano string 1 again, stop piano string 1 and shake.
The foregoing is only presently preferred embodiments of the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, all should belong to the scope of protection of the invention.
