Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.

The bone conduction earphone housing comfortable to wear of this embodiment, as shown in fig. 2-3, including receiver housing main body 1, receiver housing main body 1 includes upper casing 3 and inferior valve 2 that the opening shape is the same, upper casing 3 and inferior valve 2 buckle each other and set up, inferior valve 2 includes inner shell 21 and sets up the flexible outer 22 at inner shell 21 lateral surface, inner shell 21 and flexible outer 22 shape, the size is the same, be provided with the tie coat between inner shell 21 and the flexible outer 22 to make inner shell 21 and flexible outer 22 bond structure as an organic whole.
