Abstract
A vibration structure of a small-sized loudspeaker comprises cone paper, a hanging edge and a metal edge. The cone paper which is applied for connecting voice coils of the small-sized loudspeaker is driven by the voice coils to vibrate and generate sound waves. The hanging edge is arranged on the periphery of the cone paper and connected with the periphery of the cone paper. The hanging edge and the cone paper together form an integral body. The metal edge is arranged on the hanging edge. The metal edge, together with the hanging edge can make the vibration of the cone paper attenuated. By arranging the metal edge on the hanging edge and using the metal edge and the hanging edge to make the vibration of the cone paper attenuated, the vibration structure of the small-sized loudspeaker is enabled to have relatively high compliance. The tone quality of the small-sized loudspeaker is thus increased. The utility model further provides the small-sized loudspeaker using the vibration structure.

Embodiment
For the ease of understanding the utility model, the below is described more fully the utility model with reference to relevant drawings.Provided better embodiment of the present utility model in the accompanying drawing.But the utility model can be realized with many different forms, be not limited to execution mode described herein.On the contrary, provide the purpose of these execution modes be make to disclosure of the present utility model understand more comprehensively thorough.
Need to prove, when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be to be directly connected to another element or may to have simultaneously centering elements.Term as used herein " vertical ", " level ", " left side ", " right side " and similar statement do not represent it is unique execution mode just for illustrative purposes.
Unless otherwise defined, the employed all technology of this paper are identical with the implication that belongs to the common understanding of those skilled in the art of the present utility model with scientific terminology.Employed term is not intended to be restriction the utility model just in order to describe the purpose of concrete execution mode in specification of the present utility model herein.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
See also Fig. 1 and Fig. 2, the Microspeaker 10 of the present embodiment, involving vibrations structure 100, basin frame 200, magnetic structure 300 and voice coil loudspeaker voice coil 400.Vibrational structure 100, magnetic structure 300 and voice coil loudspeaker voice coil 400 all are arranged on the basin frame 200.
See also Fig. 3, vibrational structure 100 comprises bulging paper 110, outstanding limit 130 and metal edges 150.Drum paper 110 can be connected with voice coil loudspeaker voice coil 400 by modes such as stickups, and voice coil loudspeaker voice coil 400 can drive bulging paper 110 vibrations.When passing through the alternation tone currents in the voice coil loudspeaker voice coil 400, voice coil loudspeaker voice coil 400 and the magnetic field interaction that magnetic structure 300 produces produce vibration, and then 110 vibrations of drive drum paper, produce sound wave.
The sidewall of drum paper 110 comprises the connecting portion that the vibrating reed 111 of central region reaches around central region, and connecting portion is recessed to form the first groove 112 to a side.Please again consult Fig. 1, the first groove 112 is dovetail groove.
Specifically in the present embodiment, the first groove 112 and the second groove 132 are track type, it should be noted that the first groove 112 and the second groove 132 also can be other annular, such as annular, rectangular loop etc., change according to the shape of actual loudspeaker.
In the above-mentioned Microspeaker 10, the repeatedly copper wire 150 of bending is set on its outstanding limit 130, copper wire 150 and the 130 common vibrations that are used for decay drum paper 110 of outstanding limit, the compliance of its vibrational structure 100 is higher, and then has improved the tonequality of Microspeaker 10.
It is pointed out that copper wire 150 can be not limited to two, as long as satisfy it to the reinforcement supporting role on outstanding limit 130.See also Fig. 4, because the second groove 132 is to be formed by outstanding limit 130 side walls collapse, so outstanding limit 130 must also comprise the protuberance 134 corresponding with the second groove 132, also offer a plurality of to drum paper 110 directions extension strip groove 135 on the protuberance 134, to form a plurality of sections at protuberance 134, and then the hardness on the outstanding limit 130 of reinforcement, improve the ability of hanging limit 130 slowing down vibrations, finally improve the compliance of vibrational structure 100.
For high-power output or loud speaker with functions such as bass extension, it need to add some has flexible copper coil and silk thread and satisfies the demand that voice coil loudspeaker voice coil electric power is carried, yet for Microspeaker, because its size is limit, there is not redundant space to add required copper coil and silk thread.And in above-mentioned Microspeaker 10, please again consult Fig. 1 to Fig. 4, and copper wire 150 parts extend out to basin frame 200 outsides, and voice coil loudspeaker voice coil 400 can be electrically connected with copper wire 150 by modes such as welding.Copper wire 150 extend out to basin frame 200 outsides, can be connected with copper sheet 500, to form electrode terminal, receive the alternation tone currents of extraneous input, and be transferred to voice coil loudspeaker voice coil 400, make voice coil loudspeaker voice coil 400 produce vibration, both satisfied the demand that Microspeaker 10 electric power are carried, further saved again its required space that takies.
Be appreciated that metal edges 150 is not limited to copper wire, can also be aluminium flake, silver strip, copper-clad aluminium wire etc., to satisfy enough restoring forces are arranged, make metal edges 150 rouse the vibration of paper 110 with outstanding limit 130 common decay, simultaneously, metal edges 150 also wants to possess good conductivity.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
