In addition, preferred scheme is that said permanent magnet is an isosceles trapezoidal structure.
In addition, preferred scheme is that said magnetic conductor is provided with away from said permanent magnet and to two magnetic conduction ends of extending near said electromagnet both ends direction near the part of said electromagnet.
In addition, preferred scheme is that said elastic supporting member for supporting optical member and said lid are structure as a whole.
After adopting technique scheme, compare with traditional structure, the utility model adopts the permanent magnet of trapezium structure, and on magnetic conductor, the accepting groove of accommodating fixed permanent magnet is set, and makes firm the combining of permanent magnet and magnetic conductor, thereby has improved the stability of product.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the perspective exploded view of the utility model micro-vibration motor;
Fig. 2 is the vertical view after the utility model micro-vibration motor removes housing.
Embodiment
Like Fig. 1, shown in Figure 2; The micro-vibration motor is a rectangular configuration; Comprise the external frame of being made up of groove shape housing 11 and lid 12, wiring board 13 is fixed in the outer surface of groove shape housing 11 bottom surfaces, and is electrically connected micro-vibration motor internal circuit and outside electronic circuit.
Externally contain vibration unit in the framework and be used to drive the vibrative electromagnet 2 of vibration unit.Vibration unit is suspended in the inside of groove shape housing 11 through elastic supporting member for supporting optical member 5; And vibration unit and electromagnet 2 place on the same horizontal plane that is parallel to groove shape housing 11 bottom surfaces; The direction of vibration of vibration unit is parallel to the bottom surface of groove shape housing 11, by elastic supporting member for supporting optical member 5 elastic deformation is provided in the vibration unit vibration processes, in this implementation process; Elastic supporting member for supporting optical member 5 is structure as a whole with lid 12, and the number that can reduce part is convenient to the product assembling.The micro-vibration motor of said structure has reduced thickness of product, has realized the slimming of product.
Electromagnet is fixed in the groove shape housing 11, comprises iron core 22 and is wound in the coil 21 of iron core 22 cores, and coil 21 is electrically connected with wiring board 13.
Vibration unit comprises permanent magnet 3, and with the magnetic conductor 4 of permanent magnet 3 secure bond, wherein magnetic conductor 4 density have the effect of mass more greatly concurrently, this design can reduce number of parts equally is convenient to the product assembling.Magnetic conductor 4 is provided with away from permanent magnet 3 and to two magnetic conduction ends of extending near said electromagnet direction of both ends near the part of said electromagnet.
The operation principle of the utility model micro-vibration motor is following: the magnetic conductor 4 that combines with 3 one magnetic poles of permanent magnet is by permanent magnet 3 magnetization; The magnetic pole of two magnetic conduction ends of magnetic conductor 4 is identical; As shown in Figure 2; The N utmost point of permanent magnet 3 is towards electromagnet, and the S utmost point combines with magnetic conductor 4 away from electromagnet, and its two magnetic conduction ends were the utmost point into S after magnetic conductor 4 was magnetized.When being connected with the electric current of direction same as shown in Figure 2 in the coil 21, the right side of electromagnet is sensed as the S utmost point, and the left side is sensed as the N utmost point.Inhale with the N utmost point of electromagnet respectively mutually at the both ends of magnetic conductor 32, and the S utmost point repels each other, because electromagnet is fixed with respect to groove shape housing 12, so vibration unit can receive active force left.When being connected with rightabout electric current shown in Figure 2 in the coil 21, the polarity of electromagnet is opposite, and vibration unit can receive active force to the right.So when being connected with the signal of telecommunication of interchange in the coil 21, the polarity that electromagnet changes, alternation can take place in the force direction that permanent magnet 3 receives, thereby makes the vibration unit double vibrations produce the sense of shaking.
