A kind of frame drum with vibration silencer function
Technical field
The present invention relates to frame drum industry technology field, more particularly to a kind of frame drum with vibration silencer function.
Background technology
Common frame drum at present, logical Wood in Common Use, metal or synthetic plastic do drum chamber, then both sides drum head tighten and
Formed.Volume can be discharged because frame drum must fully vibrate, so when frame drum sends the sound, drum chamber is general
All in resonance state.For beginner, in order to reduce influence of the tum to others, it will usually placed on drum head
Foam rubber cushion or rubber blanket are practised.But, the tone color of such drum chamber is deteriorated, and gets off to cause beginner's interest to decline for a long time.Cause
This, it is desirable to provide it is a kind of to resonate the clean frame drum of small, sound to solve the problems, such as to practise frame drum.
The content of the invention
Defect and deficiency it is an object of the invention to be directed to prior art, there is provided a kind of simple structure, it is reasonable in design, make
With the convenient frame drum with vibration silencer function.
To achieve the above object, the technical solution adopted by the present invention is:
A kind of frame drum with vibration silencer function of the present invention, including drum chamber wall, it also includes rubber washer,
Two lateral walls up and down of the drum chamber wall are threaded with drum and lower drum, and upper drum is provided with drum head, and lower drum sets
It is equipped with some bandages;The upper and lower ends face of drum chamber wall is provided with the groove circle mutually matched with rubber washer;Rubber washer is tight
It is close to be nested in groove circle.
Further, the surface area in the gap of the lower drum and the surface area of bandage are 1:2.
Further, set in gap between the upper surface of the drum chamber wall and upper drum, the lower surface of drum chamber wall is with
Set in gap between drum.
After said structure, the present invention has the beneficial effect that:A kind of frame with vibration silencer function of the present invention
Son drum, including drum chamber wall, it also includes rubber washer, two lateral walls up and down of the drum chamber wall be threaded with drum and
Lower drum, upper drum is provided with drum head, and lower drum is provided with some bandages;The upper and lower ends face of drum chamber wall is provided with and rubber
The groove circle that rubber gasket is mutually matched;Rubber washer is closely nested in groove circle.When using the present invention, drum rod taps Gu skins
Afterwards, Gu skins transfer vibrations to drum, and upper drum considerably reduces the vibration of drum chamber, drum chamber by rubber washer vibration damping
On vibration be delivered to underlying rubber washer, lower drum is delivered to after rubber washer vibration damping, considerably reduce lower drum
The vibration of frame;Resonance state is substantially reduced, the generation of tum can either be reduced, in turn ensure that the tone color of frame drum drum chamber, it is to avoid
The interest of beginner is reduced because of vibration damping.The present invention has simple structure, and it is reasonable to set, the advantages of low manufacture cost.

Specific embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in Figure 1-2, a kind of frame drum with vibration silencer function of the present invention, including drum chamber wall 1, it is also
Including rubber washer 6, two lateral walls up and down of the drum chamber wall 1 are threaded with drum 2 and lower drum 3, and upper drum 2 sets
Drum head 4 is equipped with, drum head 4 is same as the prior art with the interconnection technique of upper drum 2;Lower drum 3 is provided with some bandages 5, lower drum
Frame 3 and the interconnection technique of bandage 5 are identical with drum head 4 and the interconnection technique of upper drum 2;The upper and lower ends face of drum chamber wall 1 be provided with
The groove circle that rubber washer 6 is mutually matched;Rubber washer 6 is closely nested in groove circle.
Further, the surface area of the gap 3-1 of the lower drum 3 and the surface area of bandage 5 are 1:2;Bandage 5 exists
This can both play damping effect, and the tone color of frame drum can be ensured again;Bandage 5 uses medical athletic protective type bandage.
Further, between the upper surface of the drum chamber wall 1 and upper drum 2 in gap set, the lower surface of drum chamber wall 1 with
Set in gap between lower drum 3.
When using the present invention, after drum rod taps Gu skins, Gu skins transfer vibrations to drum, and upper drum passes through rubber blanket
Circle vibration damping, considerably reduces the vibration of drum chamber, and the vibration in drum chamber is delivered to underlying rubber washer, and rubber washer subtracts
Lower drum is delivered to after shaking, the vibration of lower drum is considerably reduced;Resonance state is substantially reduced, the product of tum can either be reduced
It is raw, in turn ensure that the tone color of frame drum drum chamber, it is to avoid the interest of beginner is reduced because of vibration damping.In addition, the simple structure, design
Rationally, low cost of manufacture.
The above is only better embodiment of the invention, therefore all constructions according to described in present patent application scope,
The equivalent change or modification that feature and principle are done, is included in the range of present patent application.
