The utility model technical problem to be solved provides a kind of linear vibration electric motor, can reduce the number of part, makes the assembling process of product obtain simplifying.
To achieve these goals, the utility model provides a kind of linear vibration electric motor, comprises the protection framework of being made up of housing and lid; Said protection framework inside is provided with electromagnet, vibration unit, and the elastic component of the said vibration unit of fixed support, and wherein, said vibration unit is made up of the permanent magnet and the balancing weight of fixing said permanent magnet and magnetic conduction.
In addition, preferred scheme is, said permanent magnet over against the position be provided with said electromagnet, the both sides of said balancing weight are provided with two the projection pieces of extension to said electromagnet both ends.
In addition, preferably scheme is, said linear vibration electric motor also comprises arrangements of electric connection, and said electromagnet is electrically connected with said arrangements of electric connection.
In addition, preferred scheme is that said electromagnet is fixed in the inner surface of said protection framework by two fixtures.
In addition, preferred scheme is that the magnetic polarization direction of said permanent magnet is a horizontal direction and vertical with said electromagnet.
In addition, preferred scheme is, said elastic component be structure as a whole with said lid.
After adopting technique scheme, compare with traditional structure, the utility model adopts the balancing weight of magnetic conduction construction; Have the effect that strengthens shake sense and magnetic conduction concurrently; Reduced the number of part in the product, thereby can reduce the processing step in the assembling process, made assembling process obtain simplifying.
Description of drawings
Through below in conjunction with accompanying drawing embodiment being described, above-mentioned characteristic of the utility model and technological merit will become apparent and understand easily.

Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the utility model.Fig. 1 is the decomposition chart of the utility model linear vibration electric motor; Fig. 2 is the perspective view of the utility model balancing weight; As depicted in figs. 1 and 2; Linear vibration electric motor comprises the protection framework of being made up of housing 11 and lid 12, and arrangements of electric connection 13 is a board structure of circuit, is incorporated into the realization linear vibration electric motor inside, bottom of housing 11 and being electrically connected of external electronic circuits.Protection framework set inside is by the vibration unit of being made up of the balancing weight 4 of permanent magnet 3 and fixed permanent magnet 3; The quality that balancing weight 4 can increase vibration unit strengthens the sense of shaking; Elastic component 5 fixed weight pieces; It is inner that vibration unit is fixed in the protection framework, and in the present embodiment, elastic component 5 is structure as a whole with lid 12.Two pairs of fixed parts 51 are extended in the end of elastic component 5, and fixed part 51 is through the joint portion 41 and its secure bond of balancing weight 4 upper groove shapes.
In this implementation process, balancing weight 4 is the balancing weight of magnetic conduction, has the effect of magnetic conduction.And balancing weight 4 both sides are provided with two the projection pieces 42 of extension to the electromagnet both ends.
Fig. 3 is the operation principle sketch map of the utility model linear vibration electric motor; As shown in Figure 3; The magnetic polarization direction of permanent magnet 3 is the parallel plane horizontal direction that belongs to arrangements of electric connection 5; Permanent magnet 3 is the S utmost point near a side of balancing weight 4, is the N utmost point away from a side of balancing weight 4, and the balancing weight 4 of magnetic conduction is magnetized to the S utmost point by permanent magnet 3.The N utmost point of permanent magnet 3 is over against coil 21, and electromagnet can present certain polarity after coil 21 was connected the signal of telecommunication.When being connected with the electric current of direction same as shown in Figure 3 in the coil 21; The electromagnet left side is the S utmost point for the ultra-Right side of N; Because electromagnet is fixed, balancing weight 3 is the S utmost point near two projection pieces 42 of electromagnet, so projection piece 42 repels with the S of electromagnet 2 is extreme each other; Extremely attract each other with the N of electromagnet, vibration unit can receive active force left.Elastic component 5 provides an elastic deformation power in the vibration unit vibration processes.Equally; When coil 21 was connected with rightabout electric current, electromagnet was induced rightabout magnetic, and vibration unit receives rightabout active force; When being connected with the ac signal of certain frequency in the coil 21, vibration produces the sense of shaking thereby vibration unit can be certain frequency.
The balancing weight of the utility model is the balancing weight of magnetic conduction, has the effect that strengthens shake sense and magnetic conduction concurrently, has reduced the number of part in the product, thereby can reduce the processing step in the assembling process, makes assembling process obtain simplifying.
Under the above-mentioned instruction of the utility model; Those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description; And these improvement and distortion all drop in the protection range of the utility model, and those skilled in the art should be understood that; Above-mentioned specific descriptions are just better explained the purpose of the utility model, and the protection range of the utility model is limited claim and equivalent thereof.
