Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
Drum quieter provided by the utility model, as shown in Figure 1, 2, comprises drum mat 1, support unit and linkage unit;
Support unit comprises bracing frame 2 and fixed head 3, and the side of fixed head 3 is relatively set with two L-type bracing frames 2, and bracing frame 2 comprises orthogonal horizontal supporting plate 21 and vertical back up pad 22, and wherein horizontal supporting plate 21 is fixedly connected with fixed head 3 is vertical;
Linkage unit comprises hinge bar 4, articulated slab 5, screw block 7 and screw mandrel 8, horizontal supporting plate 21 all offers the through stopper slot 6 of flute length direction perpendicular to fixed head 3, between two stopper slots 6, erection has the screw block 7 that can slide along flute length direction, screw block 7 offers the through threaded hole perpendicular to fixed head 3, screw mandrel 8 is connected with fixed head 3 by bearing, the opposite side of screw mandrel 8 one end self-retaining plate 3 penetrates, and match with the through threaded hole on screw block 7, screw block 7 two ends are all hinged with articulated slab 5 by jointed shaft 10, also be hinged by jointed shaft 10 one end with hinge bar 4 between two articulated slabs 5, the other end of hinge bar 4 is hinged with drum mat 1 by jointed shaft 10, between the vertical back up pad 22 being articulated with two bracing frames 2 between hinge bar 4 both ends by jointed shaft 10, described jointed shaft 10 is all perpendicular with the threaded hole offered on screw block 7.
It is inner that this drum need be installed on drum with quieter, and fixed head 3 is fixedly connected with drum sidewall, and on drum sidewall, reserved aperture is greater than the hole of screw mandrel 8 diameter for wearing screw mandrel 8.With reference to shown in Fig. 3, when needs noise reduction, be positioned at outside screw mandrel 8 end of drum by regulating, make screw block 7 gradually near fixed head 3, screw block 7 drives articulated slab 5, and articulated slab 5 drives hinge bar 4, hinge bar 4 drives drum mat 1 progressively to paste and is buckled on drum head, thus plays sound deadening; When mute state removed by needs, being positioned at drum outside screw mandrel 8 end by regulating in the other direction, making screw block 7 gradually away from fixed head 3, screw block 7 drives articulated slab 5, articulated slab 5 drives hinge bar 4, and hinge bar 4 drives drum mat 1 to be progressively separated with drum head, thus removes mute state; If now continue again to make screw block 7 away from fixed head 3, then by a series of interlock, drum mat 1 between upper and lower drum head effectively intercepts area and can progressively reduce, its acoustic resonance impact inner on drum weakens further, thus the impact of this drum quieter on the tonequality of drum is also weakened further.This drum is rational in infrastructure with quieter, takies bulging inner space little, while reaching better erasure effect, easy to adjust, also very little on the impact of tympanitic note matter, has good practical value.
This drum, with in quieter, described drum mat 1 is also equipped with bipeltate pad 11, and bipeltate has softness, advantage that screen resilience is good, and its subsides are buckled in after on drum head, while noise reduction, also do not affect feel during impact.
