Description

Receiver

Technical field

The application relates to receiver, and more specifically, relates to the housing for receiver.

Background technology

Various types of microphone and receiver are used for many years.In these devices, different electronic units is installed together in housing or assembly.The acoustic apparatus of other types can comprise the parts of other types.These devices can be used in the hearing instrument of such as hearing aids, personal audio headphone and so on, or these devices can be used in other electronic equipments of such as cell phone and computer and so on.

Receiver motor typically comprises coil, yoke, armature (or lamination) and magnet.The signal of telecommunication is applied in coil, and produces magnetic field in motor, causes armature movement.The motion of armature causes vibrating membrane to vibrate, thus produces sound.Magnet, armature and yoke form magnetic circuit jointly.Yoke also can be used as keeping or support magnet or miscellaneous part.

Utility model content

According to an aspect of the present utility model, provide a kind of receiver, this receiver comprises motor, this motor comprises at least one magnet, armature and coil, the further involving vibrations film of this receiver and housing, this housing comprises the Part I and Part II that are fixed together, Part I and Part II are made up of airtight and waterproof point material, Part I and Part II are formed and define inner space, this housing has the port extending through space, wherein, magnetic field is produced by operating in inner space of motor, wherein, Part I and Part II are made up of high permeability material, this high permeability material effectively limit magnetic field is leaked to receiver outside from inner space.

This housing is substantially rigid concerning the flexure caused by the acoustic pressure in inner space.

Erosion-resisting for forming the described material of described Part I and Part II.

Described material for forming described Part I and Part II prevents the external force owing to being applied to receiver and is out of shape.

Accompanying drawing explanation

In order to understand the disclosure more up hill and dale, with reference to following detailed description and accompanying drawing, wherein:

Fig. 1 comprises the stereogram of the receiver according to the utility model numerous embodiments;

Fig. 2 comprises and has to illustrate that inner member removes the stereogram of the receiver of a part for housing according to the utility model numerous embodiments;

Fig. 3 comprises the side sectional view of the receiver according to the utility model numerous embodiments;

Fig. 4 comprises the side sectional view that the receiver of magnetic flux line is shown according to the utility model numerous embodiments.

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 have with these terms in the respective field of the inquiry corresponding relative to them and study 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 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 and is not intended to broad aspect of the present utility model to be restricted to shown execution mode.

A kind of method being provided for the housing of acoustic receivers is described herein.Produce magnetic field by the operation of motor, and these magnetic fields are advantageously included in the inside of receiver, significantly to reduce or to eliminate the leakage of magnetic field to receiver outside completely.

Referring now to Fig. 1 to Fig. 4, describe the example of receiver 10.This 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, yoke (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 of coil 18, armature 22 is moved, armature 22 moves trundle 19 then, thus initiation vibrating membrane 38 vibrates, and produces the sound expected.Sound is exported by the port 36 in housing, and is then exported 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.

The further involving vibrations film 38 of this receiver, and this housing comprises the Part I 30 and Part II 32 that are fixed together.Part I 30 and Part II 32 are made up of airtight and waterproof point material.Part I 30 and Part II 32 are formed and define inner space 34.As mentioned above, housing 14 has the port 36 extended through this housing.

Magnetic field 40 is produced by operating in inner space of motor 16.Part I 30 and Part II 32 are made up of high permeability material.This high permeability material effectively limit magnetic field 40 from inner space to the leakage of receiver outside.

In certain aspects, this housing is substantially rigid to the flexure produced by the acoustic pressure in inner space.In other examples, this material is erosion-resisting.Another in other in, this material prevents the external force owing to being applied to receiver and is out of shape.

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 execution mode is only example, and shall not be applied to restriction scope of the present utility model.
