Description
Technical field
The present invention relates to electronic device field, particularly relate to a kind of earphone and assemble method thereof.
Background technology
Along with popularizing of portable mobile termianl product, earphone is also widely used in daily life.Such as, earphone is used to listen to the music, carry out chat session etc.At present, the earphone on market has generally comprised metal front and plastic back shell, and metal front and plastic back shell are adhesively fixed by glue, forms a containing cavity, is provided with horn assembly in containing cavity, to realize the pronunciation of earphone.
But such scheme has following shortcoming: 1, because fore shell is metal material, back cover is plastic cement material; Therefore, the mode reliability that fore shell and back cover are adhesively fixed by glue is poor, in the process that earphone uses in reality, when fore shell or back cover are subject to pullling stress, being separated from each other easily appears in fore shell and back cover, thus the acoustical quality to earphone, even the normal use of earphone is impacted; 2, in the process using glue to be adhesively fixed, glue easily sticks to the outer wall of fore shell and back cover, thus impacts the outward appearance of earphone, and meanwhile, glue also easily sticks to horn assembly, thus impacts the voice effect of horn assembly.
Summary of the invention
For overcoming in prior art, the fixed form reliability of metal front and plastic back shell is poor and affect the outward appearance of earphone, the problem of acoustical quality, the object of this invention is to provide a kind of earphone and assemble method thereof.
For achieving the above object, the scheme that the present invention adopts is:
There is provided a kind of earphone on the one hand, comprise metal bezel, plastic cement bonnet, horn assembly and there is the adapter sleeve of containing cavity, realized fixing between one end of described adapter sleeve and described plastic cement bonnet by hot melt, realized fixing between the other end of described adapter sleeve and described metal bezel by riveting, described metal bezel is coordinated fixing with described plastic cement bonnet, described horn assembly is positioned at the containing cavity of described adapter sleeve.
A kind of assemble method of earphone is provided on the other hand, comprises:
Metal bezel, plastic cement bonnet, horn assembly are provided and there is the adapter sleeve of containing cavity;
One end of described adapter sleeve is fixed on described plastic cement bonnet by hot melt;
Described horn assembly is placed in the containing cavity of described adapter sleeve;
The other end of described adapter sleeve is fixed on described metal bezel by riveting.
The embodiment of the present invention is by the setting of said structure, using adapter sleeve as the fixing supporting between metal front and plastic back shell, what effectively metal front and plastic back shell are subject to pulls stress dispersion on adapter sleeve, fixing more firm, the reliability of metal front and plastic back shell is made more by force, thus to ensure the acoustical quality of earphone and normally use unaffected; Further, efficiently avoid the impact that earphone outward appearance is caused brought because glue adheres to.
