Background technique
Intelligence equipment function is more and more at present, and volume is smaller and smaller, and thickness is more and more thinner, following to produce to sounding
The performance requirement of product is higher and higher, and volume requirement is smaller and smaller.In the driver of small size, have the following problems:
1. small product size wants small, due to needing vibrating function so monomer frequency will meet the need of vibration lower than 200HZ
It asks；
2. it is small in size due to driving, cause the practical acceleration worked it out of product less than normal, it is impossible to meet clients for motive force
The demand at end；
3. small product size is small, relatively difficult using traditional connection type.
In the patent of Patent No. 201720188830.0, a kind of two-in-one driver is disclosed, though the driver is
Minitype actuator, since " frame 2 " of the driver is made using metal, in actual use, the frequency of FO is reached by test
Less than Customer Standard, there are certain drawbacks.
Summary of the invention
The invention provides a kind of miniature two-in-one driver, on the one hand reduces volume, and another aspect improves whole
Stability, while being designed using racetrack two magnetic route structure, make up the inadequate situation of the small magnetic energy of small product size.
Realize that the technical solution of the invention purpose is as follows:
A kind of two-in-one driver of ultra-thin micro, including magnet, magnet are bonded in semiclosed state magnetic cover inner bottom surface, on magnet
Surface is equipped with pole piece, which is characterized in that magnet, semiclosed state magnetic cover and the pole piece forms magnetic confining field after bonding, institute
The magnetic confining field cross section stated is racetrack, further includes the voice coil being suspended in semiclosed state magnetic cover, and voice coil is located at magnet and half and seals
Between closed state magnetic cover, voice coil and jolting plate are bonded, and jolting plate and the suspension in the outside of semiclosed state magnetic cover are connected by a snap, together
When, the suspension is fixed together with semiclosed state magnetic cover by plastic.
Further, the magnet includes main magnet and secondary magnet, and main magnet and secondary magnet are superimposed up and down, the pole
Piece is located at superposition interface.
Further, the suspension is made into using soft material.
It further, further include ZIF connector, ZIF connector is formed together with FPC pad solder by SMD technology
FPC mould group, while FPC mould group is fixed on suspension by glue gluing.
Further, two lead of voice coil is connected on FPC pad by microdot welding technology, and and ZIF connector
Conducting.
Further, the suspension includes side plate and flexible jointing-rod, the flexible jointing-rod upwards or to
Under be formed by bending curved surface.
Further, the flexible jointing-rod and plastic integrated molding.
According to above structure, the beneficial effect of the invention is:
1. effectively reducing production while guaranteeing product stability as the injection molding substrate of suspension using ultra-soft material
The FO of product.
2. designing using racetrack two magnetic route structure, it is inadequate to make up the small magnetic energy of small product size.
3. solving the problems, such as that the small connection of product is difficult in such a way that FPC is connect with ZIF.
Figure of description
Fig. 1 is the structure chart of the invention；
Fig. 2 is the cross-sectional view of the invention；
Fig. 3 is the acceleration plots of the invention.
Specific embodiment
As depicted in figs. 1 and 2, the two-in-one driver of a kind of ultra-thin micro, including magnet 1, magnet 1 are bonded in semiclosed state
2 inner bottom surface of magnetic cover, 1 upper surface of magnet are equipped with pole piece 3, and the magnet 1 includes main magnet 1-1 and secondary magnet 1-2, while main magnetic
Body and secondary magnet are superimposed up and down, and the pole piece 3 is located at superposition interface.
By the way of main magnet and secondary magnet superposition, whole magnetic flux can be effectively improved, and then improve product vibration
When acceleration.
Particularly, the magnet 1, semiclosed state magnetic cover 2 and pole piece 3 form magnetic confining field, the envelope after bonding
Closing magnetic field cross section is racetrack.
In the prior art, such as in the patent of Patent No. 201720188830.0, disclosed minitype actuator, " magnetic
Cover ", " magnet " and " pole piece ", composition is circular magnetic circuit, in the invention racetrack magnetic circuit with respect to circular magnetic circuit,
Magnetic energy product can significantly be increased, acceleration also improves one times or more.
It further include the voice coil 4 being suspended in semiclosed state magnetic cover 2, voice coil 4 is located between magnet and semiclosed state magnetic cover, voice coil
It being bonded with jolting plate 5, jolting plate 5 is connect with the suspension 6 in the outside of semiclosed state magnetic cover 2 by buckle 7, meanwhile, described is outstanding
Frame 6 is fixed together with semiclosed state magnetic cover 2 by plastic 8.
Particularly, the suspension 6 includes side plate 6-1 and flexible jointing-rod 6-2, the flexible jointing-rod 6-2S type
Curved surface is to simulate to complete by emulation technology, enhances the support of bracket while reducing driver FO.
The side plate and flexible jointing-rod are all made using the injection molding substrate of ultra-soft, and whole suspension can will swash at this time
The FO for encouraging device is reduced in the range of 160HZ, to provide better effect.
It further include ZIF connector 9, ZIF connector is connected together to form FPC mould by SMD technology and FPC pad weldering 10
Group, while FPC mould group is fixed on suspension by glue gluing.
Two lead of voice coil is connected on FPC pad by microdot welding technology, and is connected with ZIF connector.
Traditional driver mostly uses greatly the mode of electric welding to be attached with exterior electrical components, often will lead to weldering in this way
Point falls off, and influences service condition, and after using above-mentioned FPC group mould, flexible circuit board, which can be directly used, to be attached, so that
It connects relatively reliable.
The above is only the preferred embodiment of the invention, not does limit in any form to the invention
System, any simple modification to the above embodiments, equivalent variations, fall in all technical spirits created according to the present invention
Enter within the protection scope of the invention.
