Accompanying drawing explanation
Fig. 1 is the part-structure schematic diagram of Microspeaker of the present invention；
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further
As it can be seen, a kind of Microspeaker includes plastic rubber bracket 2, and magnetic circuit system, voice coil loudspeaker voice coil, diaphragm and the pad 11 for electric connection being fixed on plastic rubber bracket.
Wherein, magnetic circuit system includes the U cup 3 being fixed on plastic rubber bracket 2, is fixed on the magnet steel in U cup 3 and the washer being sticked on magnet steel.Described magnetic circuit system is used for providing magnetic field, voice coil loudspeaker voice coil to be electrically connected with by pad, after energising under the action of a magnetic field that magnetic circuit system produces, is moved up and down by the driving of Lorentz force, and driven diaphragm vibration sounding further.Described plastic rubber bracket is a slab construction, and its central authorities are provided with acoustic aperture 20, and described U cup 3 is arranged on the central authorities of plastic rubber bracket 2, and the opening of described U cup 3 is correspondingly arranged with acoustic aperture 30.Further, around acoustic aperture 20, it is additionally provided with a circle leak holes 201, for regulating the acoustic pressure inside and outside Microspeaker.
In the present invention, Microspeaker is not provided with the pcb board of transmission, but pad 11 is embedded in plastic rubber bracket 2, carry out being connected with exposed electrical, concrete, in the present invention, pad 11 is made for tin plating tablet, prepares and form integrative-structure by the way of pad 11 and plastic rubber bracket 2 use integrated injection molding.Further, the thickness of pad is less than 0.3mm more than 0.1mm.In this manner it is ensured that injection effect is best, reducing stress and concentrate, the homogeneity of product of formation is high, and reliability is high.Pad 11 is arranged on plastic rubber bracket 2 edge, and is positioned at the same side of plastic rubber bracket with described U cup 3.
Further, in the present invention, U cup 3 and plastic rubber bracket 2 are also integrated injection mo(u)lding and prepare.
When preparing Microspeaker, first one group of plastic parts 2 is provided, described plastic parts 2 is provided with pad reserved place 21, then one group of U3 cup is provided and is respectively placed on corresponding plastic parts 2, thering is provided a weld tabs 1, described weld tabs is tin plate, and thickness is less than 0.3mm more than 0.1mm.It is provided with multiple pad 11 on described weld tabs 1, pad 11 is arranged on described pad reserved place 21, carry out integrated injection molding, form the moulding of the first order.
Subsequently, mounting magnetic steel, voice coil loudspeaker voice coil and diaphragm be packaged in the moulding of forming.Form multiple Microspeaker array of packages linked together.
Finally, weld tabs is carried out die cut, make the product after encapsulation be separated into multiple Microspeaker.
The Microspeaker that the present invention provides is to be embedded at the PCB of support by tin plating steel disc, replaces the PCB of external stickup, either uses soldering still to use machine spot welding, and the effect of welding and efficiency all exceed external PCB.Improve the unfailing performance of product, and substantially increase production efficiency.
