Description
Technical field
The utility model relates to musical instrument, particularly relates to a kind of shoegaze with mute function.
Background technology
Piano is a kind of keyboard play kind musical instrument, and its sound is large, range wide, expressive force is very abundant, thus deeply likes by everybody.Current piano mainly contains upright piano and Horizontal piano, but its basic structure is all made up of casing of piano, back rack, skeleton, soundboard, string, hammered string instrument, keyboard and pedal system.Iron skeleton and soundboard are fixed on back rack usually, and string is arranged on iron skeleton, and the hammer of being pulled the trigger on hammered string instrument by keyboard hits string, and make string produce vibration, the vibration of string makes soundboard empathize, thus piano is sounded.In the process of daily study playing piano (particularly in the process of beginner's piano), the sound that piano sends all relatively owes graceful, therefore easily produces very large sound interference to household and neighbours.If someone lodges an objection, study schedule and the effect of pianist can be affected again so conversely.Particularly piano study is all generally carry out in narrow and small room at present, and narrow space affects the tone color of piano more, learns in such a case for a long time, and the as easy as rolling off a log people of making produces oppressive and irritated, thus affects learning interest and effect.
At present, the existing piano that can play in the mute state, a kind of piano muting schemes is disclosed as Chinese patent ZL201020150734.5 " has the piano of mute function ", have and install simply, easy to operate, and photoelectric detection system can be led to earphone output synthesis key sound, but still there is following defect in it:
1) regulate the quiet pedal place being positioned at piano with the gear switching device of non-mute state, in order to the flexible axle of gear switch transmitting force and seizing wire length long, such gear switch reaction is insensitive.Further, in use, along with the relaxation of deformation that wire rope is less, gear switch is just caused to complete.2) there is no micromatic setting, when the shelves bar position that stop hammer knocks string is not good, need piano be taken apart, directly regulate quiet parts.
Summary of the invention
The purpose of this utility model is to provide a kind of intelligent piano with mute function, when the piano practice that beginner uses this to have mute function is played, can not bother others.Further, this intelligent piano has sensitive gear switching device, and structure is simple, easy to operate.
The concrete technical scheme of the utility model is a kind of intelligent piano with mute function, comprise key, hammer, string and quiet parts, described key pulls the trigger the vibration of described string for triggering described hammer, and described quiet part components comprises the shelves bar that the change in location along with described hammer can contact with described hammer; The flexible axle that one end is connected with described shelves bar; Be connected with the other end of described flexible axle, and the gear switching device by making described shelves bar position change to the effect of described flexible axle; One end is connected with described shelves bar, and the shelves bar resetting means that the other end is connected with piano support, is characterized in that,
Described gear switching device comprises only sound box and only sound handle, described only sound box comprises upper plate, perpendicular side plate and arc side plate, described arc side plate has groove, described flexible axle is seizing wire, one end of flexible axle is fixed on the medium position of described only sound handle through the through hole stopped on the upper plate of sound box, only one end of sound handle is fixed in the perpendicular side plate of only sound box by rotating shaft rotation, only the other end of sound handle stretches out through the groove stopped on the arc side plate of sound box and stops outside sound box, and described rotating shaft is positioned at the oblique below of the through hole on upper plate.
Further, described only sound box is arranged on the piano outside plate of key bottom, the direction that described groove length direction and only sound handle rotate around the shaft is consistent, when only sound handle motion is to groove one end, drop-down described flexible axle, when only sound handle motion is to the groove other end, upwards loosen described flexible axle.
Further, described gear switching device also comprises stop screw, rotates the extreme position that described stop screw can limit only sound handle rotation.
Further, described shelves bar resetting means is torsion spring.
The beneficial effects of the utility model are on the basis of the piano silencer of prior art, by regulating the quiet gear switching device with non-mute state from original position in the pedal of piano, have changed to the side plate outside surface below piano key.Like this in order to flexible axle and the seizing wire moderate length of gear switch transmitting force, gear switch can not be caused to react insensitive.Further, in use, the relaxation of deformation that wire rope is less, also can not cause gear switch to complete.Gear switching device is positioned on hand, convenient adjustment.There is micrometer adjusting screw, when the shelves bar position that stop hammer knocks string is not good, directly can regulate the position of grade bar.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.
As shown in Figure 1-2, a kind of intelligent piano with mute function of the present utility model, comprise key, hammer 16, string 15 and quiet parts, described key is pulled the trigger described string 15 vibrate for being triggered described hammer 16, and described quiet part components comprises the shelves bar 6 that the change in location along with described hammer 16 can contact with described hammer 16; The flexible axle 12 that one end is connected with described shelves bar 6; Be connected with the other end of described flexible axle 12, and the gear switching device by making described shelves bar 6 position change to the effect of described flexible axle 12; One end is connected with described shelves bar 6, shelves bar 6 resetting means that the other end is connected with piano support.Described shelves bar 6 resetting means is torsion spring, and torsion spring set is on the turning axle of shelves bar 6.
Described gear switching device comprises only sound box and only sound handle 104, described only sound box comprises upper plate 101, perpendicular side plate 102 and arc side plate 103, described arc side plate 103 has groove, described flexible axle 12 is seizing wire, one end of flexible axle 12 is fixed on the medium position of described only sound handle 104 through the through hole stopped on the upper plate 101 of sound box, only one end of sound handle 104 is fixed in the perpendicular side plate 102 of only sound box by rotating shaft 105 rotation, and 105 directions rotated are consistent around the shaft with stopping sound handle 104 for described groove length direction.Only the other end of sound handle 104 stretches out through the groove stopped on the arc side plate 103 of sound box and stops outside sound box, and described rotating shaft 105 is positioned at the oblique below of the through hole on upper plate 101.Described only sound box is arranged on the piano outside plate of key bottom.
When normally playing, only sound handle 104 moves to the right-hand member of groove, and only the position of sound handle 104 is close to level, and upwards loosen described flexible axle 12, such shelves bar 6 moves backward under the effect of torsion spring, does not stop that hammer 16 knocks string 15.When quiet performance, only sound handle 104 moves to groove left end, and only the position of sound handle 104 is close to vertical, pulls down described flexible axle 12, and drives shelves bar 6 to travel forward, and stops that hammer 16 knocks string 15.
Described gear switching device also comprises stop screw 106, rotates the extreme position regulating described stop screw 106 can limit only sound handle 104 rotation, under the drive of flexible axle 12, thus regulates the position of shelves bar 6.
