Description
Technical field
The utility model belongs to the Design and manufacture field of loud speaker, is specifically related to a kind of structure of loud speaker shell fragment.
Background technology
The external mode of signal that current loudspeaker monomer adopts normally shell fragment leg contacts with exterior part, realizes the conducting of signal.In order to meet reliability when shell fragment and exterior part operating state, shell fragment should be compressed to service position after exterior part contacts with shell fragment, the elastic force that shell fragment is produced reaches the standard value of operating state, ensures contact tight, stable between shell fragment and exterior part.As shown in Figure 1, the stressed position of the fulcrum of shell fragment is generally bending forming to the elastic piece structure adopted in present stage industry, and shell fragment is when stress deformation, and the elastic force that the shell fragment reflected contacts with exterior part increases with compress variation and linearly increases.
In order to ensure the contact accurate positioning of shell fragment and exterior part, shell fragment often compresses a segment distance in advance, is suspended on the housing of loudspeaker monomer, and the elastic force that compression produces can make shell fragment be stabilized in pre-hung position.When exterior part contacts with shell fragment, shell fragment can not produce phenomenons such as rocking, and the stroke that shell fragment is compressed to service position further also can reduce, and it is accurate to ensure with the contact position of exterior part.But this design can cause shell fragment just to there is a pre-hung power before the use.
As shown in Figure 2, according to existing elastic piece structure, in order to when ensureing that shell fragment is compressed to service position C, elastic force can reach standard value, shell fragment can produce larger pre-hung power when free position A is compressed to pre-hung position B, shell fragment is in the effect of larger pre-hung power for a long time, there will be the failure phenomenon such as fatigue, fracture.
So, be necessary to design a kind of new elastic piece structure, while guarantee work elastic force reaches standard value, elastic force during shell fragment pre-hung can be reduced as far as possible, prevent shell fragment from damaging and lost efficacy.In addition, when loudspeaker monomer be applied in mobile phone need on the electronic equipment of wireless telecommunications time, the electromagnetic field that conductive component in loud speaker produces may affect the function of communication antenna.So, the conductive component in loudspeaker monomer should be reduced as far as possible.

Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar assembly or has assembly that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
As shown in Figure 3,4, the utility model provides a kind of elastic piece structure, and described elastic piece structure comprises fixed part 1, first fulcrum 2, floating slice 3 and the second fulcrum 31.One end of described fixed part 1 and one end of described floating slice 3 link together by described first fulcrum 2.Generally, described elastic piece structure is integrated, because rapidoprint bends at the first fulcrum 2 place, so when the main body of floating slice 3 from free position A when the main body of fixed part 1, first fulcrum 2 can produce elastic force as elastically-deformable fulcrum, and the size of elastic force is with compress variation linearly variation tendency.When the main body of floating slice 3 contacts at fulcrum contact position D place with the main body of fixed part 1, described second fulcrum 31 can become the fulcrum of shell fragment deformation and the arm of force between the main body of floating slice 3 and the main body of fixed part 1 is reduced, and the speed that elastic force increases with deflection can be accelerated.As shown in Figure 4, after the second fulcrum 31 becomes deformation fulcrum, continue compression floating slice 3, the slope of force variation is greater than the first fulcrum 2 as slope during deformation fulcrum.
Especially, in order to ensure that the second fulcrum 31 can not deform as the fixed part 1 of described elastic piece structure during deformation fulcrum and the first fulcrum 2, one end that described fixed part 1 is connected with the first fulcrum 2 can comprise the extension 11 extending a segment distance along short transverse.As shown in Figure 3, fixed part 1 and the first fulcrum 2, the floating slice 3 with extension 11 form rectangular configuration.When described second fulcrum 31 is as deformation fulcrum, rectangular configuration can prevent the first fulcrum 2 and fixed part 1 to be upturned, thus increases stability and the reliability of elastic piece structure.
Second fulcrum 31 described in the utility model can be positioned on described floating slice 3, described floating slice 3 can be formed one section of bending structure as the second fulcrum 31, when the main body of floating slice 3 is positioned at fulcrum contact position D, described bending structure can contact with fixed part 1, becomes the deformation fulcrum of shell fragment.Or, described second fulcrum 31 also can be positioned on described fixed part 1, described fixed part 1 can be formed a bulge-structure as the second fulcrum 31, the main body of described floating slice 3 can contact with the bulge-structure on fixed part 1 at fulcrum contact position D, and described bulge-structure becomes the deformation fulcrum of shell fragment.The utility model does not limit described second fulcrum 31 and is formed in mode on described floating slice 3 or fixed part 1, and those skilled in the art can select different modes to form the second fulcrum 31 according to actual conditions.
