Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of beam of miniature loudspeaker box, and this beam comprises an elastomer block;
This elastomer block is provided with a groove, and the upper surface of described groove and described elastomer block connects;
Be provided with an elasticity post in this groove, the upper end of described elasticity post exceeds the upper surface of described elastomer block.
The utility model also provides a kind of miniature loudspeaker box, and its bottom is fixed with a plurality of damping foots pad, and described damping foot pad adopts above-mentioned beam.
Be described in detail below in conjunction with the specific implementation of specific embodiment the beam of a kind of miniature loudspeaker box of the utility model:
Embodiment one:
Fig. 2 shows the perspective view of the beam of the miniature loudspeaker box that the utility model first embodiment provides, Fig. 3 shows the plan structure schematic diagram of the beam of the miniature loudspeaker box that the utility model first embodiment provides, Fig. 4 shows the cross-sectional view of the beam of the miniature loudspeaker box that the utility model first embodiment provides, for convenience of explanation, only show the part relevant with present embodiment.
Present embodiment provides a kind of beam, and this beam is mainly used in and is fixed on the miniature loudspeaker box bottom to play the effect of damping.This beam comprises an elastomer block 201, this elastomer block 201 is provided with a groove 202, this groove 202 connects with the upper surface of elastomer block 201, be provided with an elasticity post 203 in the groove 202, this elasticity post 203 is protruding and exceed the upper surface of elastomer block 201 from groove 202 bottoms, and the lower surface of this elastomer block 201 is generally the plane.For easy to use, the lower surface of elastomer block 201 can also be provided with adhesive-layer, in actual use, the lower surface of elastomer block 201 is mutually bonding by adhesive-layer with the outer surface of audio amplifier bottom, make this beam be fixed on the audio amplifier bottom, the part that elasticity post 203 exceeds elastomer block 201 upper surfaces then directly contacts with the supporting surface of audio amplifier.
This beam is compared with traditional beam, and the main distinction is that its elastomer block has a groove, and is provided with an elasticity post that exceeds the elastomer block upper surface in the groove, and the kinetic energy that the audio amplifier vibrations produce mainly transforms by this elasticity post.
The shock absorption principle of this beam below is described.When audio amplifier owing to playing sound excessive when vibrations of producing, at first be compressed with the contacted elasticity post 203 of supporting surface, the cross-sectional area of elasticity post 203 is less, easy deformation, its deformation quantity is bigger, promptly buffer distance is big, damping effect is relatively good like this.And the cross-sectional area of existing beam is bigger, its integral body is difficult for being compressed, when needs transform identical kinetic energy, the deformation quantity of its generation is than little many of elasticity post, therefore the kinetic energy that need in short buffer distance cabinet be shaken is reduced to zero, the damping effect of this situation is bad naturally, is easy to cause cabinet to beat.Therefore, the beam that present embodiment provides is compared with existing beam, and under the situation that transforms identical kinetic energy, its amount of elastic deformation is bigger, and buffer distance is long, and damping effect is better.
Certainly; when the cabinet vibrations are violent; elasticity post 203 is compressed into when mutually concordant with elastomer block 201 upper surfaces and may still vibrations kinetic energy all can not be transformed; this moment, elastomer block 201 meetings further be compressed; elastomer block 201 can assist to consume a part of kinetic energy in this case; this moment, elastomer block 201 and elasticity post 203 played the effect of damping jointly, and elastomer block also plays the effect of protection elasticity post.Even like this, the still more traditional beam of the compressibility of this beam is good, still can improve damping effect.
In the present embodiment, the length of elasticity post 203 and sectional area have determined the damping performance of this beam, and it specifically can determine that the elasticity post is long more according to the cabinet shock conditions of reality, easy more compression, and buffer distance is long more, and damping effect is good more; The sectional area of elasticity post is big more, and the shockproofness that can bear is big more, but its compression performance also can appropriateness weaken.Therefore, the length of elasticity post 203 and sectional area need be taken all factors into consideration factors such as buffer distance and shockproofness and determine.Be appreciated that when vibrations are violent, only rely on the cushioning effect of elasticity post 203 may need with the elasticity post do longer, at this moment its stability will be affected, because its outstanding cabinet surface is long, also is easily damaged or comes off.At this moment just need the suitably length of control elasticity post 203 elasticity of extension pieces 201, suitably increase the sectional area of elasticity post 203 simultaneously, enable to bear bigger shockproofness and improve damping effect.Therefore, when the audio amplifier shockproofness was big, the longer and sectional area that elasticity post 203 can be done was big; When the cabinet shockproofness hour, the weak point that elasticity post 203 can be done some, sectional area can be smaller.Take all factors into consideration above-mentioned factor, the length that the upper end of elasticity post 203 exceeds elastomer block 201 upper surfaces can be 1/5～1/3 of elastomer block height.The cross-sectional area of elasticity post 203 can be 1/10～1/2 of the cross-sectional area of elastomer block 201.
Embodiment two:
In the present embodiment, the shape of elastomer block 201 can have multiple, and its lower surface can be the plane, and its upper surface also can be the plane.The shape of its cross section (being the plan view shape of elastomer block 201) can be circular, oval, polygon regular shapes such as (rectangle, triangle, rhombuses etc.), can also be irregular bent limit shape, and the shape of its cross section does not influence the damping performance of beam.
In the present embodiment, the shape of elasticity post 203 can be cylindrical.
As further improvement of this embodiment, the upper surface of this elastomer block 201 can also be a convex surface, as shown in Figure 5.When elasticity post 203 is not enough to bear the shockproofness of audio amplifier, this elastomer block 201 is further compressed, in compression process, the upper surface of elastomer block and the contact area of supporting surface become big gradually, be that the elastomer block on plane is compared with upper surface like this, its cushioning effect has obtained further improvement, and then has further improved the damping effect of beam.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
