Those skilled in the art should recognize, for succinct and clearly object and the element that shows in accompanying drawing.In fact and inessential it is to be further appreciated that and can describe with specific order of occurrence or describe some action and/or step, but one skilled in the art will appreciate that such details about order.It is to be further understood that term used herein and express these terms with the respective field of inquire about with relative to them and learning and express consistent usual implication, except clearly setting forth herein.
Embodiment
Although the utility model is easy to the impact being subject to many multi-form embodiments, preferred embodiment of the present utility model shown in accompanying drawing will be described in detail in herein, be understandable that, the disclosure is considered to the example of principle of the present utility model, and does not attempt broad aspect of the present utility model to be restricted to shown embodiment.
The scheme providing receiver described herein can be used in the multiple application of such as hearing aids (HI) and so on.Also can adopt receiver described herein in other device of such as personal computer and cell phone and so on.Other example of these devices is also feasible.
Referring now to Fig. 1 to Figure 10, describe an example of receiver 10.Receiver comprises and defines inside and outside housing 14.Receiver 10 comprises motor 16 further, and motor 16 comprises the coil 18 be substantially arranged in housing 14, lamination (or magnetic supporting structure) 20 and armature 22.The electric current of the sound that representative will generate flows through coil 18.By the electric current mobile armature 22 of coil 18, armature moves trundle then, thus causes vibrating membrane vibration, and produces the sound expected.Sound is exported by a port in housing, and then by sound pipe 25.
As mentioned above, motor 16 comprises armature 22, coil 18 and magnetic supporting structure 20.Motor 16 also comprises at least one magnet 24 defining space 26.Coil 18 forms passage 28.Align with the passage 28 formed by coil 18 in the space 26 limited by least one magnet 24.Armature 22 extend partially across space 26 and passage 28.Coil 18 is formed the motion limiting armature 22.
In one aspect, coil 18 comprises the fin of the motion of restriction armature during shaking.In another example and as shown in Figure 2, coil 18 comprises the projection 30 of the motion of restriction armature 22 during shaking.Along with armature 22 move time, armature clash into projection, this has disperseed impulsive force.
In another example and as shown in Fig. 3 to Fig. 9, the part of coil is reduced to second width at the second end place being positioned at passage 28 gradually from the first width of the first end being positioned at passage 28.In certain aspects and as shown in Figures 3 to 6, the part reduced gradually of coil 18 is top 31 and bottom 33.In certain aspects, the first sidepiece 34 of coil 18 and the second sidepiece 36 reduce gradually.In other example, two sidepieces and top and bottom reduce gradually.Along with armature 22 moves, armature clashes into coil 18, and this has disperseed impulsive force.
There has been described preferred implementation of the present utility model, comprising the optimal mode for performing this utility model known to inventor.Should be understood that, shown embodiment is only example, is not limited to scope of the present utility model.
