Description

Receiver

Technical field

The utility model 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 all 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 devices of such as hearing aids, personal audio headphone and so on, or these devices can be used in other electronic installations 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 for keeping or support magnet or miscellaneous part.

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.

The method comprising locating features is described herein.Adopt this locating features, other elements on housing, receiver or other elements are located and/or are supported.Therefore, be easier to manufacture and reduce the cost of receiver.

Referring now to Fig. 1 to Fig. 3, 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.Flow through the electric current mobile armature 22 of coil 18, armature 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 extending through this housing.Housing 14 comprises features 40, and this features is constructed to position the structure of the parts of receiver 10 or receiver 10 or support.In certain aspects, be erosion-resisting for forming the material of housing.In other respects, the distortion that this material prevents the external force owing to being applied to receiver and causes.In some instances, this features (being used as location) comprises the surface portion projecting to inside.In other examples, this features comprises opening, projects in housing 14 or through housing 14 to allow the part of internal structure.

Referring now to Fig. 4, describe another example of locating features 40.In this example, the chadless portion of press-in extends from the inside of upper shell 30, to support the ring 42 keeping vibrating membrane 38.

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.
