Referring to Fig. 1, the forming method of the bolster for acoustics motor provided by a kind of embodiment of the application
Step flow chart, this method applies but is not limited to prepare in the acoustics motor of audiphone or earphone.
Fig. 2, Fig. 3 are referred to, in this embodiment, the acoustics motor 16 includes：Coil 18, magnetic portion
Part 23 and armature 22；The magnetic part 23 is formed with gap, and the coil 18 is formed with passage；The electricity
Pivot 22 passes through the gap and the passage.
Above-mentioned acoustics motor 16 be used for constitute receiver when, the acoustics motor 16 can be used in the receiver to
The power for giving vibrating diaphragm (not shown) to vibrate, makes vibrating diaphragm export sound.In acoustics motor 16, coil 18, which is constituted, to be had
One passage, magnetic part 23 can form a gap under the supporting role of magnetic support part 20.Coil 18 can
With input current, alternating magnetic field is produced when electric current flows through coil 18 in armature 22, armature 22 is then in magnet
Effect is lower to drive trundle motion, so as to trigger diaphragm oscillations by trundle, and produces desired sound.Produced
Raw sound can be exported by an opening and sound tube for the housing of receiver.
To prevent acoustics motor 16 such as dropping, fall touch in the problem of damage, can acoustics motor 16 armature
One bolster 30 is set on 22.Refer to Fig. 1, Fig. 2, the bolster for acoustics motor that present embodiment is provided
Forming method comprise the following steps：
Buffer substance is deposited on S1, the armature.
Armature 22 is also referred to as reed, its usual piece shape shape.Buffer substance can be just to be deposited on armature 22
Bolster 30, it can be initial buffer part.Buffer substance is simultaneously unformed, can be considered as buffer substance hardness or
Hardness or volume under the parameters such as volume and not up to use state.Buffer substance is deposited on armature 22 and forms block
Shape, such as rectangular blocks, (part) spherical block, cylinder or irregular shape.Buffer substance can be in electricity
The surface of pivot 22 forms projection, and then its bolster 30 formed can suppress the vibrations space of armature 22.
In this step, buffer substance can be deposited in several ways on armature 22, such as injection, smearing, point
Glue etc..Generally, deposition position of the buffer substance on armature 22 is the position of its bolster 30 formed.Compared with
Good, the deposition position of buffer substance can be set close to the junction of coil 18 and magnetic part 23, or armature
22 medium position.
Meanwhile, the armature 22 of sheet typically be provided with mutually back to both sides, it is therefore, in the present embodiment, described
Armature 22 it is mutual back to both sides at least side deposit buffer substance.As shown in Fig. 2 in order to armature 22
Comprehensively protected, the both sides of armature 22 can deposit buffer substance, entered regardless of whether the either side of armature 22 occurs
Jerk, can be effectively protected to armature 22.
In this step, the buffer substance can be selected from least one in metal, plastics, rubber, glue, ceramics
Kind.The form of buffer substance can be in fluid or colloidal state, and it be able to can be changed with form after certain time,
Such as solidify.Wherein, the buffer substance can include response type glue.Preferably, the response type glue can be with
For ultraviolet photocureable material.
In this step, optionally, the armature 22 is located at the deposited on portions buffer substance in the gap.It is based on
This, can cause the bolster 30 after shaping to be located at the gap, and then obtain motor as shown in Figure 2.
In this step, optionally, the armature 22 is located at the deposited on portions buffer substance of the passage.It is based on
This, can cause the bolster after shaping to be located at the passage, and then obtain motor as shown in Figure 3.
Certainly, it is more preferable protection armature, armature 22 is close to the junction of the coil 18 and magnetic part 23
Position deposits buffer substance.
S2, the buffer substance are shaped to bolster, and the bolster can suppress the impact endurance test shock of the armature；Its
In, deformation of the buffer substance during the bolster is shaped to is controllable.
In this step, buffer substance passes through form (such as hardness or volume or the adhesive strength to armature 22
Etc. parameter) be changed as bolster 30.Deformation of the buffer substance in forming process can be controlled (controllable), real
In border, the purpose of control buffer substance deformation can be reached by controlling the conditional parameter of shaping, such as, pass through control
Environment temperature processed, ambient humidity, the material composition of buffer substance, the temperature of armature, buffer substance depositing temperature (just
Beginning temperature), the conditional parameter such as the amount of buffer substance control buffer substance deformation.
Wherein, the controllable hardness that can be embodied in buffer substance of deformation, shape (volume, length, width, area,
Diameter) etc. the change (rate) of parameter can control, in addition, deformation is controllable, to may also mean that buffer substance is formed slow
The intended shape of stamping 30 can be controlled.
Such as, the buffer substance maintains original shape during the bolster is shaped to.In the present embodiment,
Buffer substance controls its deformation to be maintained zero (not producing deformation) by being deposited on armature 22, is reaching shaping
Time reaches end shaping after the predetermined state parameter such as predetermined hardness, and now, buffer substance is shaped to bolster.
For another example, buffer substance constant deformation during curing molding is bolster.The constant deformation can be with
Including：Expansion rate, the shrinkage factor of the volume of buffer substance；The rate of change of buffer substance telescopic, size
The parameters such as rate of change it is constant.In addition, being that Part-spherical (is similar to the bulge on the surface of armature 22 in buffer substance
Or raised) when, control the rate of change for keeping constant that expands or shrinks of its diameter to also belong to constant deformation.
In this step, buffer substance can be shaped to bolster in the given time.Wherein, molding time is (predetermined
Time) time used in expectation state can be reached for buffer substance.Specifically, the time of the shaping is (above-mentioned pre-
Fix time) can be 0.1 second to 300 seconds.
To obtain preferably buffering and damping effect, the hardness of the bolster 30 can be shore A50~D90.Institute
The weight for stating bolster 30 can be 2.0E-6 (2.0 × 10-6) gram~0.05 gram.
Length of the bolster 30 along the direction of vibration of armature 22 is 0.005 millimeter~0.08 millimeter.Can also
It is interpreted as, bolster 30 is 0.005 millimeter~0.08 millimeter by the protrusion height on the surface of armature 22.
By above scheme as can be seen that in the application by the armature of acoustics motor be provided with the bolster,
When acoustics motor is given a shock impact after dropping, armature strikes bolster, has disperseed the impulsive force of armature, it is suppressed that
The flexural shock amplitude of armature, and then prevent armature from adsorbing cisco unity malfunction by magnetic part.Therefore, the present embodiment
The method provided can effectively protect armature.
The effect above can also be confirmed in Fig. 4, it can be seen that what the present embodiment was provided has above-mentioned buffering
The acoustics motor (solid line) of part is than traditional acoustics motor (dotted line) for not possessing suppression acoustics armature vibration function
Protecting effect can be significantly improved when being given a shock impact.
