Embodiment
About aforementioned and other technology contents, characteristics and effect of the present utility model, in the detailed description of a following cooperation preferred embodiment with reference to the accompanying drawings, can clearly present.
Consult Fig. 3, Fig. 3 is the preferred embodiment that the utlity model has the electronic equipment 200 of vibration damping structure 100, this electronic equipment 200 is a notebook computer 200, but not as limit, this notebook computer 200 has a casing 300, is arranged on a sound hole 500 and two fixing columns 310 of casing 300, and two fixing columns 310 lay respectively at the both sides of sound hole 500, and each fixing column 310 has one and is connected in the pilum 311 and of casing 300 by pilum 311 upwardly extended projections 312.
In the present embodiment, vibration damping structure 100 can be in conjunction with loudspeaker 400 and be installed in the casing 300 of notebook computer 200, make loudspeaker 400 sound that loudspeaker 400 are produced corresponding to sound hole 500 places send casing 300 via sound hole 500, and, then can reduce the normal operation that casing 300 that vibration that loudspeaker 400 produce is passed to notebook computer 200 by vibration damping structure 100 has influence on other electrical assemblys on the casing 300 when work by the setting of vibration damping structure 100.
In the present embodiment, vibration damping structure 100 comprises the adjutage 2 that a vibration damping body 1 and two is connected in vibration damping body 1 and is fixed in fixing column 310 separably.
Two adjutages 2 are connected on the both ends of the surface 11 of vibration damping body 1.Each adjutage 2 all has one first extension 21, one second extension 22 and one the 3rd extension 23.In the present embodiment, one end of one end of first extension 21 and second extension 22 is connected on the end face 11 of vibration damping body 1 at intervals, the other end of the other end of first extension 21 and second extension 22 interconnects, thereby the connecting body of first extension 21 and second extension 22 structure that roughly takes the shape of the letter U; The 3rd extension 23 is roughly L-shaped and have one first section portion 231, one second section portion 232 and one the 3rd section portion 233, first section portion 231 and the 3rd section portion 233 all extend along the length direction of vibration damping body 1, second section portion 232 extends and is connected between first section portion 231 and the 3rd section portion 233 along the width direction of vibration damping body 1, a wherein side 14 and its free end that the 3rd section portion 233 extends to vibration damping body 1 are loop configuration, can snugly sheathedly be fixed on the fixing column 310 of electronic equipment 200.Therefore, in the present embodiment, each adjutage 2 is the sides 14 that are connected the end face 11 of vibration damping body 1 and extend to vibration damping body 1.
Because general elimination vibration is to utilize the stressed resiliently deformable that produces of material to absorb vibration force, elasticity coefficient (k value when selected material, claim stiffness (stiffness) again) during less assembly, just bigger amount of deformation can be produced and vibrational energy can be absorbed, therefore, these adjutages 2 of present embodiment adopt the long-pending slim-lined construction less than vibration damping body 1 in longitudinal cross-section, the elasticity coefficient that makes these adjutages 2 is less than vibration damping body 1, how to reach effectiveness in vibration suppression as for these adjutages 2, be described in more detail as follows.
Consult Fig. 4, because loudspeaker 400 are to be combined in vibration damping body 1, can produce vibration (supposing wherein have a plurality of frequency contents) when loudspeaker 400 running, this vibrational energy can be sent to vibration damping body 1 and along the length direction transmission of vibration damping body 1, shown in the direction of arrow of Fig. 4.And when vibrational energy is passed to adjutage 2, because adjutage 2 and the long-pending drop in the longitudinal cross-section of vibration damping body 1, can make only has the frequency content of a particular range could pass through adjutage 2 in the vibration of vibration damping body 1, and remaining frequency content will be extended arm 2 and filter.And adjutage 2 is the design of slim-lined construction, make the elasticity coefficient of adjutage 2 less than the elasticity coefficient of vibration damping body 1, thereby, when vibrational energy when adjutage 2 transmits, along with adjutage 2 bears the resiliently deformable that vibrational energy produces, just can sponge vibrational energy, reach the purpose of utilizing adjutage 2 attenuation vibrations by this.
And wherein, because first extension 21 and second extension 22 are interconnected to form a U type structure Design, vibrational energy can transmit in first extension 21 and second extension 22 simultaneously, when the vibrational energy on both sides is passed to the joint of first extension 21 and second extension 22, both meetings are collided and the better energy of subduing vibration mutually, to reach preferable effectiveness in vibration suppression.
Generally speaking, the utility model is by the design less than vibration damping body 1 of the elasticity coefficient of adjutage 2, make vibration that loudspeaker 400 produced and when being passed to casing 300 via vibration damping body 1, adjutage 2, can decay significantly, to guarantee the normal operation of other electrical assemblys in the notebook computer.
Moreover owing to vibration damping structure 100 directly is sheathed on the fixing column 310 of casing 300, and adjutage 2 is one-body molded with vibration damping body 1, does not need additionally to increase the vibration damping spare part, so can reduce the cost of making on going up and assembling.Certainly, adjutage 2 can also utilize modes such as welding, bonding, fixing to be connected with vibration damping body 1 with vibration damping body 1.
In the present embodiment, first extension 21 and second extension 22 are connected in the end face 11 of vibration damping body 1, but also can be connected in other surfaces of vibration damping body 1 in other variation pattern.In addition, first section portion 231 of the 3rd extension 23 also can be connected in any position of first extension 21 or second extension 22 except the joint that is connected in first extension 21 and second extension 22.And the 3rd section portion 233 of the 3rd extension 23 and the means of fixation between the casing 300 do not exceed with present embodiment, and it also can be that modes such as any other clamping separably, affixed, screw lock are fixed on the casing 300.
In addition, the longitudinal cross-section of the 3rd extension 23 long-pending can be again less than the sectional area of first extension 21 and second extension 22, so that can there be littler elasticity coefficient the 3rd extension 23 and has better effectiveness in vibration suppression, as shown in Figure 5.
In sum, the electronic equipment 200 that the utlity model has vibration damping structure 100 by the elasticity coefficient of the adjutage 2 of vibration damping structure 100 less than vibration damping body 1, make the vibration that loudspeaker 400 time are produced in work, by vibration damping body 1 and adjutage 2 time, can significantly decay, reaching the effect of vibration damping, and do not need to increase extra vibration damping spare part, thus can reduce make go up and assembling on cost and reach the purpose of this utility model.
The above person of thought, it only is preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, be every simple equivalent variations and modification of being done according to the scope and the model utility description of the utility model claims, all still belong in the scope that the utility model patent contains.
