Abstract
The utility model relates to a motor used for an acoustic apparatus. The motor comprises an armature, at least one magnet, coils and a magnetic supporting structure. The at least one magnet defines a space. The coils form a channel. The space defined by the at least one magnet and the channel formed by the coils are aligned. A part of the armature extends to pass through the space and the channel. The motor also comprises fluid or gel which is arranged in the motor and resists movement of the armature.
Description
Technical field
The application relates to receiver, and more specifically, relates to the vibrations protection of receiver.
Background technology
Various types of microphones and receiver (transducer) are used for many years.In these devices, different electrical parts are all installed together in shell or assembly.For example, receiver typically comprises coil, bobbin, lamination and other parts, and these parts are all installed in receiver shell.The acoustic apparatus of other type can comprise the parts of other type.Motor typically comprises coil, yoke or lamination and armature, and they have formed magnetic circuits jointly.
Can in the multiple application such as hearing aids, use transducer.Also can in other application such as personal computer or cell phone, use these devices.
As mentioned above, receiver has armature.Armature is a kind of moving component, and it moves along with electric current, thus the magnetic field that causes the variation in receiver.
Receiver bears polytype impulsive force.For example, if adopt receiver in personal computer or cell phone, this device may drop.The generation jerk that drops like this, it may damage or be offset the parts of receiver.
Utility model content
According to first aspect of the present utility model, a kind of motor for acoustic apparatus is provided, this motor comprises armature, at least one magnet, coil and magnetic support structure; Described at least one magnet limits a space; Described coil forms passage; Align with the described passage being formed by described coil in the described space being limited by described at least one magnet; And the part of described armature extends through described space and described passage, wherein, described motor also comprises fluid or gelinite, and this fluid or gelinite are disposed in motor, and described fluid is resisted the motion of described armature.
According to second aspect of the present utility model, described fluid or gelinite are magnetic fluids.
According to the third aspect of the present utility model, described fluid or gelinite are attracted to described at least one magnet, and described fluid or gelinite comprise iron powder.
According to fourth aspect of the present utility model, described fluid or gelinite are attracted to described at least one magnet, and described fluid or gelinite comprise ferriferous oxide.
According to the 5th aspect of the present utility model, described fluid or gelinite are disposed in opening.
According to the 6th aspect of the present utility model, described fluid or gelinite are disposed in described passage.
Brief description of the drawings
In order to understand more up hill and dale the disclosure, with reference to following detailed description and accompanying drawing, wherein:
Fig. 1 comprises according to the perspective view of the receiver of the utility model numerous embodiments;
Fig. 2 comprises according to the side sectional view of the motor of the receiver of the utility model numerous embodiments.
Those skilled in the art should recognize, for succinct and object and show the element in accompanying drawing clearly.It is to be further appreciated that and can describe or narrate some action and/or step with specific order of occurrence, but one skilled in the art will appreciate that such details about order is in fact also inessential.It is to be further understood that term used herein has the common implication consistent with expression with these terms in the field separately with respect to their inquiries and study with expressing, except clearly setting forth herein.
Embodiment
Although the utility model is easy to be subject to the impact of many multi-form execution modes, preferred implementation 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 the execution mode shown in not attempting the broad aspect of the present utility model to be restricted to.
Can in the multiple application such as hearing aids (HI), use the scheme that receiver is provided described herein.Also can in other device such as personal computer and cell phone, adopt receiver described herein.Other example of these devices is also feasible.
Referring now to Fig. 1 to Fig. 2,, an example of receiver 10 has been described.Receiver comprises the housing 14 that restriction is inside and outside.Receiver 10 further comprises motor 16, and motor 16 comprises the coil 18, lamination (or magnetic support structure) 20 and the armature 22 that are placed in substantially in housing 14.The electric current of the representative voice being generated flows through coil 18.Through the electric current mobile armature 22 of coil 18, armature 22 is mobile drive pin again, thereby causes barrier film vibration, and produces the sound of expecting.Sound is exported through a port in housing, and then exports through sound tube 25.
As mentioned above, motor 16 comprises armature 22, coil 18 and magnetic support structure 20.Motor 16 also comprises at least one magnet 24 that limits a space 26.Coil 18 forms passage 28.Align with the passage 28 being formed by coil 18 in the space 26 being limited by least one magnet 24.The part of armature 22 extends through space 26 and passage 28.Motor also comprises and being disposed in motor 16 and fluid or the gelinite 30 of the motion of restriction or opposing armature 22.
In some respects, fluid or gelinite 30 are magnetic fluids.In other example, fluid or gelinite 30 are attracted to described at least one magnet 24, and comprise iron powder.In another other example, fluid or gelinite 30 are attracted to described at least one magnet 24, and comprise ferriferous oxide.
In certain aspects, fluid or gelinite 30 are disposed in opening 26.In other side, fluid or gelinite 30 are disposed in passage 28.
Describe preferred implementation of the present utility model herein, comprised known for inventor for carrying out the optimal mode of this utility model.Should be understood that, shown execution mode is only example, is not limited to scope of the present utility model.
