Certainly, the example above is only that the present embodiment is applied to the example of hearing aid, and the utility model is not restricted to
This, such as, the motor in the present embodiment can also be applied to earphone, microphone etc..
In the present embodiment, armature 2 is arranged on magnetic support component 4 and is supported by magnetic support component 4
(support).Wherein, armature 2 is that permeability magnetic material is formed with magnetic support component 4, to form magnetic path.
In the present embodiment, magnetic support component 4 can support armature 2 so that armature 2 can vacantly through passage 11 and
Gap 33.Magnetic support component 4 provides mount point for the position of armature 2, so as to ensure 2 present position of armature.Meanwhile magnetic support
Component 4 supports magnetic part 3 to form a gap 33.Specifically, magnetic part 3 includes the magnet of two parallel and facing settings
31st, 32, magnetic part 3 can fix a magnet 31 and away from another magnet 32 (same location is fixed), so that in two magnetic
Gap 33 is formed between body 31,32.
Magnetic support component 4 supports magnet 31 and armature 2 at the same time, the shape of the magnetic support component 4 can have it is a variety of,
Such as slab construction or bending structure or U-shaped structure etc., correspondingly, magnetic support component 4 is on 100 housing of receiver
Installation site also have it is a variety of, magnetic support component 4 can be installed in 100 housing of receiver, can also be folded in housing
On, be either fixed on the side wall of housing or be fixed on the bottom wall 201 of housing etc..
Please continue to refer to Fig. 1, Fig. 2, Fig. 3, in this embodiment, for ease of installing magnetic support component 4, the magnetic branch
Support part part 4 is slab construction.The coil 1, armature 2, magnetic part 3 are located at the side of the magnetic support component 4.The tablet
The magnetic support component 4 of structure can be located between the upper shell 10 and lower housing shell 20 of receiver 100, form sandwich-type
(sandwich) structure.
Meanwhile using slab construction magnetic support component 4 when, facilitate the installation of armature 2 and magnetic part 3 connect.Together
When, the coil 1, armature 2, magnetic part 3 are located at the side of the magnetic support component 4, when scope of readers is to Fig. 2, coil
1st, armature 2 and magnetic part 3 are respectively positioned on the lower section of magnetic support component 4.
So set, magnetic support component 4 can be covered on lower housing shell 20 with top-down installation direction, magnetic portion
One magnet 32 can also be first fixed on the bottom wall 201 of lower housing shell 20 using top-down mode by part 3, another magnet 31 with
Magnetic support component 4 is assembled in a manner of top-down on lower housing shell 20, and upper shell 10 afterwards can be equally used from upper
Mode under and is fixed on the top of magnetic support component 4.As it can be seen that the magnetic support component 4 of slab construction be conducive to motor or
The assembly orientation of most of element is unified in receiver 100, so as to facilitate automated production.
In this embodiment, magnetic support component 4 is slab construction, meanwhile, a surface (following table of magnetic support component 4
Face) for magnet installation after can it is vacant go out larger area for armature 2 assembling, so as to lifted the installation of armature 2 spirit
Activity.
Housing in view of receiver 100 is usually rectangular shape, to adapt to 100 hull shape of receiver, the magnetism
