Description
Technical field
The utility model relates to a kind of vibrating motor, is specifically related to reduce the horizontal vibration motor of product resonance frequency.
Background technology
Horizontal vibration motor of the prior art comprises the protection framework, and protection framework inside is provided with the elastic component of vibration unit and fixed support vibration unit.Elastic component generally includes deformations, and in the vibration unit vibration processes, deformations elastic deformation can take place follows the vibration unit vibration.
In the process that realizes the utility model, the inventor finds that the deformations of prior art is generally U type or L type structure, and the deformations of this traditional structure is owing to be difficult to bear the big stress that receives in the vibration processes, and the life-span of product is shorter.And the deformations spring ratio k of traditional structure is bigger, is unfavorable for reducing the resonance frequency F0 of product.Therefore, be necessary the horizontal vibration motor of said structure is improved, to avoid above-mentioned defective.
The utility model content
The utility model technical problem to be solved provides a kind of horizontal vibration motor, can prolong the useful life of product, and reduces the resonance frequency F0 of product.
To achieve these goals; The utility model provides a kind of horizontal vibration motor; Comprise the protection framework of being made up of housing and lid, said protection framework inside is provided with the elastic component of vibration unit and the said vibration unit of fixed support, and said elastic component comprises deformations; Wherein, said deformations is provided with Wave-shaped structural.
Preferred scheme is that said Wave-shaped structural comprises a crest and a trough at least.
In addition, preferably scheme is, said protection framework is a rectangular configuration, and said elastic component is symmetrical distribution along said protection framework central axis, comprises two symmetrical said Wave-shaped structurals.
In addition, preferably scheme is, said elastic component also comprises the joint portion that combines with said protection framework, the fixed part of fixing said vibration unit, and said deformations is between said joint portion and said fixed part; And said Wave-shaped structural is near said joint portion.
In addition, preferred scheme is that said elastic component and said lid are structure as a whole.
After adopting technique scheme; Compare with traditional structure, the utility model is through being provided with Wave-shaped structural, because the crest of Wave-shaped structural and trough part all can meet with stresses on deformations; Therefore increase the ability that product meets with stresses, prolonged the useful life of product; And Wave-shaped structural reduced the spring ratio of elastic component, reduced the resonance frequency F0 of product.

Fig. 4 is the vertical view of structure shown in Figure 3.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed description.
Fig. 1 is the STRUCTURE DECOMPOSITION sketch map of the utility model horizontal vibration motor; As shown in Figure 1; The horizontal vibration motor is a rectangular configuration; Comprise the protection framework of being made up of housing 11 and lid 12, circuit board 13 is fixed in the outer surface of housing 11, and realization linear vibration electric motor inside is electrically connected with external electronic circuits.Protection framework inner packet is drawn together by permanent magnet 31, magnetic conductor 32 and balancing weight 4 and is combined the vibration unit formed successively; And the elastic component 5 of the said vibration unit of fixed support; Wherein permanent magnet 31 is fixed by magnetic conductor 32; Magnetic conductor 32 is fixed by balancing weight 4, and balancing weight 4 is fixed by elastic component 5.
Fig. 2 is the fundamental diagram of the utility model horizontal vibration motor, and is as shown in Figure 2, and permanent magnet 31 magnetizes along the horizontal direction that is parallel to circuit board 13, the direction that the magnetic polarity direction is extended perpendicular to iron core 22.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, and the N utmost point of permanent magnet 31 is over against electromagnet, and the S utmost point is away from electromagnet.Magnetic conductor 32 is sensed as the S utmost point by permanent magnet 31; Magnetic conductor 32 both sides are provided with the projection piece of extension to iron core 22 two ends; Right-hand end projection piece and electromagnet repel each other; Left side projection piece and electromagnet 2 attract each other, because electromagnet is fixed with respect to the protection framework, so vibration unit can receive active force left.Equally, 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 will change, vibration unit is because left and right directions replaces stressed and corresponding vibration.
Fig. 3 is the perspective view of the utility model horizontal vibration motor elastic component and lid, and Fig. 4 is the vertical view of structure shown in Figure 3, and like Fig. 3 and shown in Figure 4, elastic component 5 is structure as a whole with lid 12; Elastic component 5 is the central axis two parts symmetrical of relative moment female cap body 12; Two parts include the joint portion 51 that is combined as a whole with lid 12; The fixed part 52 of fixed weight piece 4, and the deformations 53 between joint portion 51 and fixed part 52 (among the figure, symmetric part does not mark).The part that is connected with joint portion 51 on the deformations 53 is a undaform connecting portion 531, and in the present embodiment, connecting portion 531 is provided with a crest and a trough; In the vibration processes; The peak part of connecting portion 531 and trough part all can meet with stresses, and have avoided stress too concentrated, have increased the ability that elastic component 5 meets with stresses; Prolonged the service time of elastic component 5, thereby prolonged the useful life of entire product.
According to following formula:
; Wherein m refers to the quality of vibration unit; K refers to the coefficient of elasticity of elastic component; Can draw, under the constant situation of vibration unit quality m, the size of coefficient of elasticity k can determine the size of resonance frequency F0.The deformations 53 of this implementation process makes elastic component 5 have less coefficient of elasticity owing to have the connecting portion 531 of Wave-shaped structural, thereby the resonance frequency F0 of product is reduced.
In the present embodiment, the quantity of undaform connecting portion 531 crests and trough is not limit.
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, for example; Can change the quantity of undaform connecting portion crest and trough; 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.
