The various exemplary embodiments of the present invention are described in detail now with reference to accompanying drawing.It should also be noted that unless additionally have Body illustrates, the parts illustrated the most in these embodiments and positioned opposite, the numerical expression of step and numerical value are not intended to this The scope of invention.
Description only actually at least one exemplary embodiment is illustrative below, never as to the present invention And any restriction applied or use.
May be not discussed in detail for technology, method and apparatus known to person of ordinary skill in the relevant, but suitable In the case of when, described technology, method and apparatus should be considered a part for description.
It is shown here that any occurrence should be construed as merely exemplary with in all examples discussed, and not It is as restriction.Therefore, other example of exemplary embodiment can have different values.
It should also be noted that similar label and letter represent similar terms, therefore, the most a certain Xiang Yi in following accompanying drawing Individual accompanying drawing is defined, then need not it is further discussed in accompanying drawing subsequently.
The invention provides a kind of extensional vibration motor, the structure of Magnet and coil is changed by this extensional vibration motor Enter, improve the vibration performance of extensional vibration motor, enable vibrating mass assembly to receive the electromagnetic action of equilibrium when vibration.
As it is shown in figure 1, described extensional vibration motor includes housing 1, vibrating mass assembly, shell fragment assembly 3, coil 4 and outer Connection circuit, described housing 1 is internal has receiving chamber, and described receiving chamber is for accommodating all parts of vibrating motor.Described vibration Block assembly is arranged in described receiving chamber, and vibrating mass assembly includes mass 21 and the Magnet 22 being fixed on mass 21, institute Stating the mass 21 main counterweight as vibrating mass assembly, the Magnet 22 of described mass 21 for coordinating generation electricity with coil 4 Magnetic force, drives vibrating mass assembly extensional vibration.Especially, the magnetic pole of described Magnet 22 is along genesis analysis, the i.e. N of Magnet 22 Pole or S pole are up or down.
Described shell fragment assembly 3 is configured to be suspended from described receiving chamber described vibrating mass assembly, upper and lower at vibrating mass assembly During vibration, shell fragment assembly 3 is for providing linear guide effect and being returned to the active force of equilbrium position.Described shell fragment assembly 3 can To include two or more shell fragment, shell fragment is separately positioned on the upper side and lower side of vibrating mass assembly, so that vibrating mass assembly is suspended from Accommodating in chamber, shell fragment assembly 3 provides support smoothly.
In the vibrating motor that the present invention provides, described vibrating mass assembly mainly structure in noncircular cross section, such as may be used To be the structure such as cuboid-type, fillet cuboid-type, so vibrating mass assembly has the differentiation of long axis direction and short-axis direction.Institute Stating the direction that long axis direction is the length along vibrating mass assembly, described short-axis direction is then the width along vibrating mass assembly Direction.Shown in phantom above-mentioned long axis direction and the short-axis direction that in Fig. 1, two length on mass 21 are different.
Described coil 4 is arranged on the lateral location of described Magnet 22, in the embodiment shown in Fig. 1, extensional vibration horse Reaching and include two coils 4, two coils 4 are separately positioned on the vibrating mass assembly both sides along short-axis direction, coil 4 and Magnet 22 Position corresponding.When vibrating mass assembly is in equilbrium position, as in figure 2 it is shown, coil 4 is just to described Magnet 22, Magnet 22 The position height of lower edges corresponding with the position of coil 4 coiling.Coil is overall in coil cylindrical structure, Magnet upper and lower Edge is corresponding with the position at the cross section place of coil tube.So, the magnetic line of force can be more accurately by the district at coil 4 place Territory, increases the magnetic flux of coil 4, accordingly, the Lorentz force produced when improving magnetic flux change.
It should be noted that in the embodiment of figure 1, coil 4 is arranged on the both sides along short-axis direction vibrating mass assembly, Coil 4 self is parallel to long axis direction.And in other embodiments, such as in the middle of vibrating mass assembly, there is gap, or magnetic Ferrum 22 is when vibrating mass assembly is distributed along long axis direction, and described coil self can also be parallel to short-axis direction, and the present invention is the most right This limits.Under normal circumstances, as long as ensureing that coil is vertically distributed, and side is just to Magnet.
In the extensional vibration motor that the present invention provides, by coil and Magnet relative to the configuration of position so that Magnet The magnetic field produced can produce, preferably through the position at coil place, the electromagnetic force that intensity is higher and stable.The opposing party Face, owing to being configured with the shell fragment assembly being positioned at vibrating mass assembly the upper side and lower side so that vibrating mass assembly can be suspended from receiving chamber In, it being difficult to wiping during up-down vibration and meet other parts, the design of this structure enables coil just to the balance with vibrating mass assembly Position so that it is the electromagnetic force of symmetry, balance can be received during up and down motion.The extensional vibration motor that the present invention provides solves The problem that vibration is uneven, electromagnetic force is unstable.
Described external circuits is connected for realizing point with external electronic device, and described coil is electrically connected with described external circuits Connect.
Preferably, in order to make vibrating mass assembly have more magnetic field in vibration processes by coil 4, such as Fig. 2 further Shown in, the height of described coil 4 self can be more than the height of described vibrating mass assembly self.And vibrating mass assembly up-down vibration Amplitude then less than or equal to the altitude range of coil 4 self, the amplitude of vibrating mass assembly can be by the structure of shell fragment assembly 3 Limit.So, in the altitude range being in coil 4 all the time of vibrating mass assembly, the magnetic field concentrated through magnetic conductive board 23 can More through coil 4.
Can be coated with magnetic conductive board 23 in the upper and lower surface of described Magnet 22, described magnetic conductive board 23 will be for conducting from N pole The magnetic line of force to S pole is concentrated, is deflected to predetermined region, to obtain the distribution of optimal magnetic force, promotes to greatest extent and passes through The magnetic induction line density of coil 4, improves electromagnetic force.Comprehensive features above, the magnetic line of force can more accurately, concentrate pass through coil The region at 4 places, increases the magnetic flux density of coil 4, accordingly, the Lorentz force produced when improving magnetic flux change.The present invention Being not limiting as to arrange on Magnet magnetic conductive board, in some embodiments, arranging magnetic conductive board on Magnet can increase magnetic Field intensity, brings the lifting of electromagnetic force.In other cases, it is also possible to be not provided with magnetic conductive board.
The version of described coil, Magnet and mass have many in selectable embodiment, the present invention is the most right This limits.Following connection with figures provides several optional embodiment.
Embodiment as shown in Figure 1,3, described vibrating mass assembly can include that two pieces of masses 21, described Magnet 22 set Put between two pieces of described masses 21.Two pieces of masses 21 are positioned at the two ends of vibrating mass assembly long axis direction, mass 21 In centre position.Described extensional vibration motor includes that two coils 4, two coils 4 are separately positioned on axle short with vibrating mass assembly On the receiving cavity wall that two sidewalls in direction are relative.In this embodiment, the simple in construction of vibrating mass assembly, it is possible to letter Change assembly technology.
