Description
Technical field
The utility model relates to receiver, more specifically, relates to vibrations protection (shock protection) of receiver.
Background technology
Various types of microphone and receiver (transducer) have employed a lot of year.In such devices, different electric components is accommodated in shell or assembly together.Such as, receiver generally comprises coil, bobbin (bobbin), lamination except other elements, and these elements are all contained in receiver shell.The acoustic equipment of other types can comprise the element of other types.Motor generally comprises coil, yoke or lamination and armature, and these elements together form magnetic circuit.
Transducer can be used in the multiple application such as such as hearing aids.Also can use these equipment in other application such as such as personal computer or cell phone etc.
As mentioned above, receiver has armature.Armature is movable element, and when the magnetic field that electric current changes in receiver, armature just moves.
Receiver bears multiple external force.Such as, if adopt receiver in personal computer or cell phone, this equipment may drop.The impulsive force produced that drops like this may be damaged the element of receiver or the element of receiver is offset.

Embodiment
Because the utility model is easily subject to the impact of multiple multi-form embodiment, therefore preferred embodiment of the present utility model shown in the drawings, and be described in greater detail in this article, be understandable that, the disclosure is considered to the example of principle of the present utility model, and and is not intended to relative broad range of the present utility model to be restricted to shown embodiment.
The scheme that receiver is provided described herein can be used in the multiple application such as such as hearing aids (HI).Also can adopt receiver described herein in other equipment such as such as personal computer and cell phone etc.Also can use in other equipment.
Referring now to Fig. 1 to Fig. 5, the example of receiver 10 is described.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 produce 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, subsequently through sound pipe 25 by a port in housing.
As mentioned above, motor 16 comprises armature 22, coil 18 and magnetic supporting structure 20.Motor 16 also comprises at least one magnet 24, and this magnet defines space 26.Coil 18 forms passage 28.Align with the passage 28 formed by described coil 18 in the space 26 limited by least one magnet 24 described.Armature 22 extend partially across space 26 and passage 28.Motor comprises pad 30 further, and this pad 30 is formed with opening 32.Armature 22 extends through opening 32, and opening 32 limits the movement of armature 22.
In in as shown in Figures 2 and 3 some, pad 30 is arranged to the end near at least one magnet 24 described.In as shown in Figure 2 other, pad 30 is arranged in the end of coil 18.In as shown in Figure 2 other, pad is arranged in described between at least one magnet and described coil 18.
In some instances, pad 30 is made up of plastics.In other examples, pad is made up of metal.
As shown in Figure 4, pad 30 can be made up of single-piece.As shown in Figure 5, pad 30 is made up of two parts, and in some respects, these two parts are linked together.
There has been described the preferred embodiments of this 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.
