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.

Describe herein and provide method concerning the flexure caused by the acoustic pressure in inner space being the housing of substantially rigid to receiver.Method described herein is easy and manufacture economically.

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.The electric current flowing through coil 18 makes armature 22 move, and 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 extending through this housing.Housing 14 concerning by inner space 34 the flexure that causes of acoustic pressure be substantially rigid.
