Nowadays, piano is to be in the sight of people as a kind of common musical instrument, the increasing head of a family wishes to cultivate the speciality of child in piano, musicianship and the music knowledge of child is increased with this, therefore also buy piano in increasing family, child can practise in extracurriliar or time at weekend, but in such time period, the rest of surrounding neighbours will inevitably be had influence on, if therefore abandon practicing qin, the chance of a large amount of exercises can be wasted.With regard to above situation, need to be equipped with a kind of device that can control piano volume to piano, while can ensureing to practice qin, do not affect other people daily life and rest.
Utility model content
The purpose of this utility model is the volume control structure proposing a kind of piano, can control the size of piano volume, does not affect life and the rest of people around while ensureing to practice the qin time.
For reaching this object, the utility model by the following technical solutions:
A volume control structure for piano, comprises acoustical panel, and described acoustical panel can move between the first position and the second position; Under primary importance, described acoustical panel is between hammer and string and make hammer not contact string; In the second place, hammer can contact string.
Further technical characteristic, described volume control structure also comprises coupling arrangement and draw-gear, and described coupling arrangement is flexibly connected acoustical panel and piano frame, and described draw-gear affects acoustical panel, when draw-gear starts, acoustical panel moves to primary importance by the second place.
Further technical scheme, described coupling arrangement comprises pin and spring, and described pin is fixed on piano frame, and described spring one end is fixed on described pin, and the other end is connected with described acoustical panel.
Preferably, described spring is scroll spring.
Further technical scheme, described draw-gear comprises traction rope and pedal, and described traction rope one end is connected with acoustical panel, and the other end is connected with pedal.
Further technical scheme, described sound volume control device also comprises guide rail, and described guide rail is fixed on piano frame, and the side of described acoustical panel is placed in described guide rail, and along described guide rail movement.
Further technical scheme, described traction rope is rigidity traction rope.
Further technical scheme, described acoustical panel is schistose texture, comprises hard layer and interlayer, layer centered by described hard layer, and interlayer is superficial layer and for two-layer, described one deck interlayer contacts with hammer, another layer interlayer and string contact.
Further technical scheme, is provided with froth bed between described hard layer and interlayer.
The beneficial effects of the utility model:
The volume control structure of the piano that the utility model provides, the acoustical panel be flexibly connected with piano frame is affected by draw-gear, when making to need to reduce volume, acoustical panel can be between the hammer of piano and string, make hammer beat on acoustical panel, knocking of described acoustical panel buffering hammer, makes the vibration weakening of string, and then sound reduces, effectively prevent the situation affecting other people rest caused owing to playing the musical instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of the volume control structure of the piano that the utility model embodiment provides;
Fig. 2 is the structural representation of the acoustical panel that the utility model embodiment provides.
Wherein, 1, acoustical panel; 2, pin; 3, scroll spring; 4, traction rope; 5, pedal; 6, guide rail; 7, hard layer; 8, froth bed; 9, interlayer.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the volume control structure that the utility model embodiment provides.The volume control structure of piano, comprise acoustical panel 1, coupling arrangement and draw-gear, acoustical panel 1 is flexibly connected with piano frame by described coupling arrangement, and draw-gear affects acoustical panel 1, when draw-gear starts, acoustical panel 1 is between hammer and string, when can make piano, the impulsive force of hammer is cushioned by acoustical panel 1, makes the vibration weakening of string, the sound that piano sends reduces, and can not bother the rest of people around; When draw-gear does not start, acoustical panel 1 is away from hammer, and now during piano, the intensity of sound sent is normal.
As shown in Figure 1, coupling arrangement comprises pin 2 and scroll spring 3, and described pin 2 is fixed on piano frame, and described scroll spring 3 one end is fixed on described pin 2, and the other end is connected with described acoustical panel 1.Present embodiment adopts scroll spring 3, and scroll spring 3 has good reset, and service time is long.
As shown in Figure 1, described draw-gear comprises traction rope 4 and pedal 5, and described traction rope 4 one end is connected with acoustical panel 1, and the other end is connected with pedal 5, and wherein traction rope is rigidity traction rope, can select steel wire etc.
Traction rope 4 is affected by pushes pedals 5, traction rope 4 pairs of acoustical panels 1 apply a pulling force, and acoustical panel 1 moves under the effect of pulling force, in the region that during arrival piano, hammer and string contact with each other, hinder hammer directly to contact with string, the scroll spring 3 on acoustical panel 1 is elongated accordingly; When pedal 5 lifts, power on traction rope 4 disappears, the power of extending owing to causing scroll spring 3 disappears, scroll spring 3 shrinks, rewind on pin 2, scroll spring 3 is connected with acoustical panel 1, and now acoustical panel 1 is subject to the pulling force of scroll spring 3, and acoustical panel 1 leaves the region that above-mentioned hammer and string can contact.
Sound volume control device also comprises guide rail 6, described guide rail 6 is fixed on piano frame, the side of described acoustical panel 1 is placed in described guide rail 6, when traction rope 4 pairs of acoustical panels 1 apply pulling force, acoustical panel 1 moves along guide rail 6, utilize guide rail 6 can limit the scope of activities of acoustical panel 1, can prevent acoustical panel 1 from rocking because discontinuity produces and cause acoustical panel 1 to produce with other structures of piano colliding, cause damage being pulled in the process that rope 4 and scroll spring 3 pull.
Be illustrated in figure 2 the structural representation of acoustical panel, acoustical panel 1 is schistose texture, comprise hard layer 7, froth bed 8 and interlayer 9, layer centered by described hard layer 7, interlayer 9 is superficial layer and is two-layer, described one deck interlayer 9 contacts with hammer, another layer interlayer 9 and string contact, froth bed 8 is between hard layer 7 and interlayer 9, bondingly between several lamella forms, described acoustical panel can cushion the impulsive force that hammer knocks, and weakens sound.
More than describe preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
