Description
Technical field
Electroacoustic field is the utility model is related to, one kind is specifically related to and drives Ultrathin speaker more.
Background technology
Along with the continuous progressive and innovation of technology, increasing consumption electronic product is gradually entered in the form of different
The popular visual field, such as flat panel TV, its application is to have popularized.But due to current electronic product have increasingly been towards it is frivolous
To change, miniaturization, the thickness of TV also thins down, although having brought people's high definition and ultra-thin visual enjoyment,
The simultaneously inevitable weaknessization that result in terms of tonequality, or even be not as full simple and honest as the tonequality of CRT electroacoustic, consumer is listening
Demand in terms of feel hardly results in satisfaction.Based on this, start soundbar speaker products occurred, have to the tonequality of flat panel TV
Certain improvement result.
Undoubtedly, for the design to any a speaker products, the realization of its acoustic part be all it is vital,
And among these, loudspeaker just become the part being primarily upon.In the prior art, the top dome in vibrating diaphragm centre position is typically designed as non-
Tabular (such as cheese), or tabular is designed as, but generally use metal or paper wood matter, so inevitably
Bring two problems：It is first, smaller using the roof structure of non-tablet, its effective radiating area；Second, top dome is according to metal
Material, although rigidity is good, density height and quality weight, the sensitivity of product can be reduced, is although reduced according to paper wood matter close
Degree and quality, but rigidity is obvious poor, the frequency response curve of product is unsmooth, easily produces polarization.
Utility model content
In view of the above-mentioned problems, technical problem to be solved in the utility model is：A kind of more driving Ultrathin speakers are provided, its
Effective radiating area is improved by the improvement to top dome material and also not easily leaded to while product sensitivity is improved partially
Shake.
In order to solve the above problems, the technical solution of the utility model is：
A kind of more driving Ultrathin speakers, including the vibrating diaphragm and at least two that shell and the cage connection are fixed together
Individual separate driver element；The driver element includes voice coil unit and the magnetic circuit being correspondingly arranged with the voice coil unit
