Fig. 1 is the exploded view of linear vibration motor according to an embodiment of the invention.Fig. 3 is according to a reality of the invention
Apply the sectional view of the linear vibration motor of example.
As shown in figure 1, housing includes upper casing 11 and lower casing 20.Upper casing 11 and lower casing 20 are snapped together, with them
Portion forms cavity.For convenience of explanation, housing is set to cuboid.Certainly, in other examples, the section of housing can be near
Like the shape of cuboid, such as ellipse, track type, as long as with relative major axis and short axle.The material of housing can
To be, but not limited to, metal, plastics, ceramics etc..
In this example embodiment, coil 18 is 2, and permanent magnet 16 is 2.The adjacent long side of 2 coils 18 with 2 permanent magnetism
Gap between body 16 is relative.And the long side 26 of 2 coils has the identical sense of current.For example, as shown in Figures 2 and 3, line
Circle 18 is arranged on lower casing 20.Coil 18 is connected by FPCB19 with external circuit, with transmitting telecommunication number.Preferably, line
Property vibrating motor also include pole piece 17, coil 18 sets around pole piece 17.Pole piece 17 can gather magnetic induction line.
Preferably, housing has the first lug boss 21, and coil 18 is arranged on the first lug boss 21.For example, such as Fig. 1
With shown in 3, lower casing 20 is projecting inward to cavity, to form the first lug boss 21.Coil 18 is arranged on by way of bonding
On one lug boss 21.In this way, the gap between permanent magnet 16 and coil 18 is smaller, can wear more magnetic induction lines
Coil 18 is crossed, so as to improve the size of Lorentz force.
In one example, as shown in figure 4, flexible member is shell fragment 15.Shell fragment 15 includes be used to be connected with housing the
One connecting portion 22, for the second connecting portion 23 that is connected with oscillator and in the middle of first connecting portion 22 and second connecting portion 23
Elastic arm 30, elastic arm 30 be straight sheet.The elastic arm 30 of straight sheet, reduces the manufacture difficulty of shell fragment 15, and the knot of shell fragment 15
Structure intensity is high.Shell fragment 15 reduces the damage in process, improves service life without being bent.
Further, since the linear vibration motor vibrates along short-axis direction, the size of the extension direction of principal axis of shell fragment 15 is unrestricted,
There can be bigger length.So, the stress and resonant frequency of shell fragment 15 are relatively low.
Those skilled in the art can set the thickness of shell fragment 15 according to actual conditions.
For example, shell fragment 15 is located between oscillator and the side wall of upper casing 11, returned with being provided for oscillator along the elasticity of short-axis direction
Multiple power.Preferably, shell fragment 15 is 2, and oscillator is located between 2 shell fragments 15.Oscillator is suspended at coil by two shell fragments 15
On 18.
Preferably, the second lug boss, one end of flexible member are provided with the wall of direction of vibration in counterweight part
It is connected with the second lug boss.The connection for being set to flexible member of second lug boss provides space.For example, the side for passing through welding
Second connecting portion 23 is welded on the second lug boss by formula.
In addition, can so avoid vibration processes and in fall-down test counterweight part to the rigid collision of shell fragment 15,
So as to improve the reliability of shell fragment 15.
In one example, the 3rd lug boss 12 is provided with the wall of direction of vibration in housing, flexible member
The other end is connected with the 3rd lug boss 12.The connection for being set to flexible member of 3rd lug boss 12 provides space.For example, such as
Shown in Fig. 6, the 3rd lug boss 12 is provided with the first side wall 24 and second sidewall 25 of extension direction of principal axis.3rd lug boss
12 to cavity internal projection.The first connecting portion 22 of shell fragment 15 is welded on the 3rd lug boss 12.
In addition, the 3rd lug boss 12 can avoid vibrating motor shell fragment 15 and in vibration processes and fall-down test
The sharp impacts of side wall 24 and second sidewall 25, to reduce vibrating motor vibrating noise, improve the reliability of shell fragment 15.
For example, as shown in fig. 7, shell fragment 15 is two.The first connecting portion 22 of each shell fragment 15 and elastic arm 30 are into set angle
Degree, such as 90 °.Shell fragment 15 is L-shaped.First connecting portion 22 is together with the sidewall weld along short-axis direction of upper casing 11.So,
Shell fragment 15 reduces in the space taken along along short-axis direction, increases the oscillation space of oscillator.
In one example, in the insertion of permanent magnet 16 counterweight part.For example, counterweight part is mass 13.As shown in figure 5, matter
Gauge block 13 is made by wolfram steel.Counterweight part sets fluted 14, and permanent magnet 16 is set within grooves 14.Pass through this side
Formula, can avoid permanent magnet 16 from protruding from mass 13, reduce the volume of oscillator, and reduce even avoid permanent magnet 16 with
Other elements collide.
Preferably, there is reinforcement 31, to improve the bulk strength of mass 13, it is to avoid matter between adjacent groove 14
Gauge block 13 occurs to be broken or failed in shaping and fall-down test.
For example, mass 13 can be integrally formed by the way of pouring.Reinforcement 31 and groove 14 are poured simultaneously to be built up
Type.In this way, mass 13 can have higher structural strength.
In one example, the adjacent long side of 2 coils 18 is symmetrical arranged relative to the center line in gap.2 permanent magnets
16 models are identical, and the magnetic induction line that two gaps of adjacent permanent magnet 16 come out respectively constitutes two closed magnetic circuits.The long side 26 of coil
Center line relative to gap is symmetrical arranged.So, coil 18 is equal for the amount of force of two permanent magnets 16, direction phase
Together, the vibration of oscillator is more balanced, it is to avoid polarize.
In one example, linear vibration motor also includes pole piece 17.The coil 18 that pole piece 17 is used to gather energization is produced
Magnetic field, improve magnetic field intensity.Pole piece 17 is 2, and coil 18 is set around pole piece 17, and the two is corresponded.Housing by
Magnetic conductive material is made, and the material of such as upper casing 11 and lower casing 20 is SUS-430.Each pole piece 17 is connected with housing,
So that the side wall adjacent with the pole piece 17 of housing to be magnetized, magnetic force is formed between side wall and permanent magnet 16.For example, the polarity of housing
It is identical with the polarity of pole piece 17 and housing connection one end.
For example, as shown in figure 3, the adjacent side of two permanent magnets 16 is N poles, magnetic direction is downward perpendicular to coil 18.
After energization, the two long side cutting magnetic induction line of two coils 18.Coil 18 by the right Lorentz force act on, oscillator by
Left reaction force F effect.
The sense of current of two coils 18 is opposite.According to Ampere's law, the lower end of pole piece 17 on right side is S poles, due to second
Side wall 25 is geomagnetic into S poles close to the pole piece 17；The lower end of the pole piece 17 in left side is N poles, is somebody's turn to do because the first side wall 24 is close
Pole piece, therefore it is geomagnetic into N poles.Now, the permanent magnet 16 on right side is by the repulsive force of second sidewall 25, and the power is to the left.Left side
Permanent magnet 16 is acted on by the attraction of the first side wall 24, and the power is to the left.Two power are produced simultaneously.So, oscillator receives shell
" electromagnetic force " F ' of wall effect.
When vibration reaches high order end, the sense of current of two coils 18 changes.Now, the reaction force of coil 18
" electromagnetic force " F ' effects of F and shell wall change simultaneously, are changed into the right.
The reaction force F of coil 18 is identical with " electromagnetic force " F ' action directions of shell wall, and the two together constitutes oscillator and shaken
Dynamic driving force.So as to substantially increase the driving force of linear vibration motor, the response time of vibrating motor is effectively shortened,
Improve vibration sense.
