Description
Technical field
The utility model relates to a kind of damping element and the loudspeaker of using this damping element, particularly a kind of damping element and loudspeaker that are used for LCD inside.
Background technology
In recent years, traditional cathode-ray tube display (CRT monitor that promptly is commonly called as) is replaced by LCD gradually, main cause is that the amount of radiation that LCD discharges is far smaller than CRT monitor, and LCD also reduces significantly in this manufacturing cost in several years.At present, LCD on the market nearly all is equiped with loudspeaker, and major part all is to be assembled in LCD inside.In general, loudspeaker are that the mode with screw closure is locked together on the carrying housing of LCD inside, yet the effect that is difficult for reaching vibration damping in the mode of screw closure, therefore when loudspeaker sent the sound of low frequency frequency, the vibration of its generation can make LCD produce noise and cause rocking of picture.
Therefore, how increasing the effect of vibration damping, make LCD more can not produce noise and avoid rocking of picture, is to be worth those skilled in the art to be worthy of consideration ground.
Summary of the invention
The utility model main purpose provides a kind of damping element and the loudspeaker that use this damping element, and this damping element can deduct the vibration that loudspeaker produce, and makes LCD more can not produce noise and can avoid taking place the situation of picture weave.
In order to reach above-mentioned purpose and other purposes, the utility model provides a kind of damping element, and it is made of elastic material, and this damping element comprises one first cylinder, one second cylinder and a cone.Wherein, the radial dimension of second cylinder is greater than the radial dimension of this first cylinder, and is provided with one first annular groove and one second annular groove in second cylinder.In addition, cone then connects second cylinder and first cylinder.
Also have an axial hole at above-mentioned damping element, this axial hole is arranged on second cylinder.
In order to reach above-mentioned purpose and other purposes, the utility model provides a kind of loudspeaker, and these loudspeaker are installed on the carrying housing of a use for electronic equipment, and this carrying housing has a plurality of jacks.Above-mentioned loudspeaker comprise a horn main body and at least two damping elements, and wherein the side of horn main body is provided with at least two collars, and damping element then is made of elastic material.This damping element comprises one first cylinder, one second cylinder and a cone.And the radial dimension of second cylinder is greater than the radial dimension of this first cylinder, and is provided with one first annular groove and one second annular groove in second cylinder.In addition, cone then connects second cylinder and first cylinder.Wherein, first annular groove is by collar institute fit, and first cylinder and cone then wear the jack on the bearing structure, and makes this second annular groove by this jack institute fit.
The beneficial effects of the utility model are, because damping element of the present utility model is to be made of elastic material, therefore when loudspeaker send low frequency frequency sound, its vibration meeting is absorbed by damping element, and can not allow the carrying housing produce vibration, therefore, LCD more can not produce noise and can avoid picture weave, simultaneously, this kind structure can reduce built-up time, enhances productivity.

Embodiment
Below in conjunction with accompanying drawing, to this novel above-mentionedly illustrates in greater detail with other technical characterictic and advantage.
Please refer to Fig. 1, Fig. 1 is the explosive view of the loudspeaker of embodiment of the present utility model, and these loudspeaker 10 comprise a horn main body 100 and two damping elements 110.Wherein, the inside of horn main body 100 for example is provided with loud speaker (not illustrating), in order to send the sound.And horn main body 100 also comprises two collars 101, and the two above-mentioned collars 101 are separately positioned on the both sides of horn main body 100, and has trepanning 102 on the collar 101, and the diameter of this trepanning 102 is less than the diameter of second cylinder 112 of damping element 110.
Please refer to Fig. 2, Fig. 2 is the damping element of embodiment of the present utility model.This damping element 110 is made of elastic material, and in the present embodiment, this elastic material is a rubber.Damping element 110 comprises one first cylinder 111, one second cylinder 112 and a cone 113, and wherein the radial dimension of this second cylinder 112 is greater than the radial dimension of first cylinder 111, also promptly: the diameter of second cylinder 112 is greater than the diameter of first cylinder 111.And second cylinder 112 is provided with one first annular groove 1121 and one second annular groove 1122.In addition, also be provided with an axial hole 1123 on second cylinder 112, this axial hole 1123 runs through the center of second cylinder 112.This axial hole 1123 is easier to be extruded in order to make second cylinder 112, so that second cylinder 112 is easier to by the trepanning on the collar 101 102 (Fig. 1 is consulted in cooperation), this axial hole 1123 also can be set according to circumstances and not yet this area has the technical staff of common knowledge.
Then, please be simultaneously with reference to Fig. 1 and Fig. 2, when assembling, the assembler can be with damping element 110 extruding, allow the damping element 110 can be by the trepanning 102 on the collar 101, so that the collar 101 energy fits first annular groove 1121.Above-mentioned step just can allow damping element 110 be fixed on the horn main body 100.
Then, please be simultaneously with reference to Fig. 2 and Fig. 3, Fig. 3 is the loudspeaker of embodiment of the present utility model and the combination schematic diagram between the carrying housing, carrying housing 20 is arranged in the LCD (not illustrating), this carrying housing 20 is provided with a container structure 21 that protrudes backward, this container structure 21 is used to take in the required spare part of LCD, as signal of video signal circuit, VGA drive circuit, power module and signal terminal module etc.And, on this container structure 21, also being provided with a plurality of jacks 22, the diameter of these jacks 22 is greater than the diameter of first cylinder 111.Therefore, again that first cylinder 111 is past drop-down after the assembler can also insert first cylinder 111 in alignment with jack 22, make cone 113 also pass jack 22, and allow second annular groove 1122 by 22 fits of jack (as shown in Figure 4).Thus, the assembler just can be fixed on loudspeaker 10 on the carrying housing 20.
Because damping element 110 is made of elastic material, therefore when loudspeaker 10 send the sound of low frequency frequency, its vibration meeting is absorbed by damping element 110, and can not allow 20 generations of carrying housing vibrate.Therefore, LCD more can not produce noise and can avoid the situation of picture weave yet.
In addition, the assembler is on being assembled in loudspeaker 10 carrying housing 20 time, after only needing first cylinder 111 is inserted in jack 22, again with first cylinder 111 toward drop-down, just loudspeaker 10 can be fixed on the carrying housing 20.Compared to existing mode with screw closure, damping element 110 of the present utility model can significantly reduce assembler's built-up time, thereby increases production efficiency.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection range of the present utility model.
