A kind of flat vibration motor of ultrathin, including lower bracket components, vibration component on lower bracket components and The casing to match with lower bracket components;The vibration component includes mass block, n magnet steel and m elastic slice;On the mass block Equipped with k through-hole and m groove;Each through-hole is symmetrically distributed on mass block, and each groove is symmetrically distributed in mass block Outer edge on;Each elastic slice is welded on each groove, and each magnet steel is symmetrically embedded in each through-hole;Each equal position of magnet steel In the surface of lower bracket components.
The present invention makes coil using FPC rolled copper foil, reduces the height of coil, while curved using the small radian of straight formula Bent elastic slice makes mass block, magnet steel all in sustained height space, reduce the height of motor, to realize the ultrathin of motor.
Preferably, the lower bracket components include bottom bracket, coil and FPC pad on bottom bracket;Coil Both ends are welded on FPC pad, and each magnet steel is respectively positioned on the surface of coil.
Preferably, the bottom bracket is equipped with annular convex platform;Each elastic slice is symmetrically welded on annular convex platform, casing with The outer edge of annular convex platform is fixedly connected.
Preferably, the coil includes 2 layers of insulating film, a layer PI film and a+1 layers of FPC pressure between 2 layers of insulating film Prolong copper foil;PI film and FPC rolled copper foil are spaced apart.
Preferably, each elastic slice includes the first fixing end, the second fixing end, with the first fixing end and the second fixing end The arc-like sheet being all connected with;Each first fixing end is welded on each groove, and each second fixing end is welded on annular convex platform.
Preferably, n, m and k are even number, the value of n is less than the value of k.
Therefore, the invention has the following beneficial effects: the present invention makes coil using FPC rolled copper foil, reduces coil Height, while elastic slice being used to make mass block and magnet steel in sustained height space, reduces the height of motor, realize vibration The ultrathin of motor;The configuration of the present invention is simple, it is easy for installation.
Detailed description of the invention
Fig. 1 is a kind of main view of the invention;
Fig. 2 is a kind of explosive view of the invention;
Fig. 3 is a kind of top view of vibration component of the present invention;
Fig. 4 is a kind of structural schematic diagram of coil of the invention.
In figure: lower bracket components 1, vibration component 2, casing 3, bottom bracket 11, coil 12, FPC pad 13, mass block 21, Magnet steel 22, elastic slice 23, annular convex platform 111, insulating film 121, PI film 122, FPC rolled copper foil 123, through-hole 211, groove 212, One fixing end 231, the second fixing end 232, arc-like sheet 233.
Specific embodiment
The present invention is described further with specific embodiment with reference to the accompanying drawing:
Embodiment as depicted in figs. 1 and 2 is a kind of flat vibration motor of ultrathin, including lower bracket components 1, is set to Vibration component 2 on lower bracket components and the casing 3 to match with lower bracket components;As shown in Fig. 2, the lower bracket components packet Bottom bracket 11 is included, coil 12 and FPC pad 13 on bottom bracket;As shown in figure 3, the vibration component includes mass block 21,4 magnet steel 22 and 4 elastic slices 23;The mass block is equipped with 4 through-hole 211 and 4 grooves 212;As shown in Figure 1, each Elastic slice includes the first fixing end 231, the second fixing end 232, the arc-like sheet being all connected with the first fixing end and the second fixing end 233;Each through-hole is symmetrically distributed on mass block, and each groove is symmetrically distributed on the outer edge of mass block;Each One fixing end is welded on each groove, and each magnet steel is symmetrically embedded in each through-hole by glue;It welds at the both ends of coil On FPC pad, FPC pad plays the role of turn-on power, and each magnet steel is respectively positioned on the surface of coil;Casing plays support The effect of motor operation and protection internal structure of motor.
Wherein, bottom bracket is equipped with annular convex platform 111;Each second fixing end is welded on annular convex platform, casing and ring The outer edge of shape boss forms an entirety by welding;Each elastic slice is welded on annular convex platform by the second fixing end, ring Shape boss plays a supporting role to elastic slice;The circular arc size of elastic slice can adjust according to actual needs, and circular arc is bigger, middle position Smaller, elastic force is smaller;The thickness and length of elastic slice can also be adjusted according to the opportunity demand of motor.
