The present invention provides a kind of extensional vibration motor, which changes the structure of magnet and coil
Into improving the vibration performance of extensional vibration motor, enable to vibrate block assembly and receive balanced electromagnetic action in vibration.
As shown in Figure 1, the extensional vibration motor includes shell 1, vibration block assembly, elastic slice component 3, coil 4 and outer
Circuit is connect, there is accommodating chamber inside the shell 1, the accommodating chamber is used to accommodate all parts of vibrating motor.The vibration
Block assembly is arranged in the accommodating chamber, vibrates the magnet 22 that block assembly includes mass block 21 and is fixed on mass block 21, institute
Main counterweight of the mass block 21 as vibration block assembly is stated, the magnet 22 of the mass block 21, which is used to cooperate with coil 4, generates electricity
Magnetic force, driving vibration block assembly extensional vibration.Particularly, the magnetic pole of the magnet 22 is distributed along longitudinal direction, i.e. the N of magnet 22
Pole or the pole S are upward or downward.
The elastic slice component 3 is configured to for the vibration block assembly being suspended from the accommodating chamber, above and below vibration block assembly
When vibration, elastic slice component 3 is used to provide linear guide effect and is returned to the active force of equilbrium position.The elastic slice component 3 can
To include two or more, elastic slice is separately positioned on the upper side and lower side of vibration block assembly, so that vibration block assembly is suspended from
In accommodating chamber, elastic slice component 3 provides stable support.
In vibrating motor provided by the invention, the vibration block assembly is mainly in the structure of noncircular cross section, such as can
To be the structures such as cuboid-type, rounded cuboid type, so vibration block assembly has the differentiation of long axis direction and short-axis direction.Institute
Stating long axis direction is along the direction of the length of vibration block assembly, and the short-axis direction is then the width along vibration block assembly
Direction.Two different dotted lines of length in Fig. 1 on mass block 21 show above-mentioned long axis direction and short-axis direction.

Up to including two coils 4, two coils 4, which are separately positioned on, vibrates block assembly along the two sides of short-axis direction, coil 4 and magnet 22
Position it is corresponding.When vibration block assembly is in equilbrium position, as shown in Fig. 2, magnet 22 described in 4 face of coil, magnet 22
Lower edges position height it is corresponding with the position of 4 coiling of coil.Coil is integrally in coil cylindrical structure, magnet it is upper and lower
Edge is corresponding with the position where the cross section of coil tube.In this way, the magnetic line of force can more accurately pass through the area where coil 4
Domain increases the magnetic flux of coil 4, the Lorentz force generated when correspondingly, improving magnetic flux change.
It should be noted that in the embodiment of figure 1, coil 4 is arranged in along the two sides of short-axis direction vibration block assembly,
Coil 4 itself is parallel to long axis direction.And in other embodiments, such as vibration block assembly among there are gap or magnetic
For iron 22 when vibrating block assembly along long axis direction distribution, the coil itself can also be parallel to short-axis direction, and the present invention is not right
This is limited.Under normal conditions, as long as guaranteeing that coil is distributed vertically, and side face magnet.
In extensional vibration motor provided by the invention, by the configuration to coil and magnet relative position, so that magnet
The magnetic field of generation can preferably pass through the position where coil, generate the higher and stable electromagnetic force of intensity.Another party
Face, due to enabling vibration block assembly to be suspended from accommodating chamber configured with the elastic slice component for being located at vibration block assembly the upper side and lower side
It is interior, it is not easy to wipe when the vibrations are up and down and encounters other components, this structure design enables coil face and vibrates the balance of block assembly
Position enables the electromagnetic force that symmetrical balance is received when its up and down motion.Extensional vibration motor provided by the invention solves
The problem that vibration is uneven, electromagnetic force is unstable.
The external circuits are used to be electrically connected with external electronic device realization point connection, the coil with the external circuits
It connects.
Preferably, there are more magnetic fields by coil 4 in vibration processes to further make to vibrate block assembly, such as Fig. 2
Shown, the height of the coil 4 itself can be greater than the height of the vibration block assembly itself.And vibrate block assembly up-down vibration
Amplitude be then less than or equal to the altitude range of coil 4 itself, the amplitude for vibrating block assembly can be by the structure of elastic slice component 3
It is limited.In this way, vibration block assembly is in always in the altitude range of coil 4, the magnetic field concentrated through magnetic conductive board 23 can
More pass through coil 4.
Magnetic conductive board 23 can be covered in the upper and lower surface of the magnet 22, the magnetic conductive board 23 from the pole N for that will conduct
The magnetic line of force to the pole S is concentrated, is deflected to scheduled region, to obtain optimal magnetic force distribution, is promoted pass through to greatest extent
The magnetic strength line density of coil 4 improves electromagnetic force.In summary feature, the magnetic line of force more acurrate, concentration can pass through coil
Region where 4 increases the magnetic flux density of coil 4, the Lorentz force generated when correspondingly, improving magnetic flux change.The present invention
Magnetic conductive board must be arranged on magnet by being not intended to limit, and in some embodiments, magnetic conductive board, which is arranged, on magnet can increase magnetic
Field intensity brings the promotion of electromagnetic force.In other cases, magnetic conductive board can also be not provided with.
