the end face, used for being attached to a face, of the telephone receiver shell main body is provided with a flexible outer layer, and the flexible outer layer comprises a first contact area arranged adjacent to the concave cambered surface and a second contact area arranged far away from the concave cambered surface;
the hardness of the first contact area is less than the hardness of the second contact area.
In the above technical scheme, the flexible outer layer is a silica gel outer layer.
In the technical scheme, the hardness of the first contact area is 10-30A, and the hardness of the second contact area is 40-80A.
Among the above-mentioned technical scheme, receiver shell main part includes inferior valve and epitheca, the open form of epitheca with the open form of inferior valve matches so that the two lock each other, flexible outer setting is in on the terminal surface of the attached people's face of inferior valve.
In the above technical scheme, the lower casing includes the inner shell and sets up the flexible skin in the inner shell lateral surface, flexible skin with the inner shell bonding sets up.
In the above technical scheme, a bonding layer is arranged between the inner shell and the flexible outer layer, and the inner shell and the flexible outer layer are bonded into an integral structure through the bonding layer.
In the above technical scheme, the upper shell is a plastic upper shell, and the inner shell is a plastic inner shell.
The utility model has the beneficial effects that:
according to the bone conduction earphone receiver shell, the side wall of one side of the receiver shell main body is set to be the concave cambered surface, the shape of the concave cambered surface is similar to that of the outer side surface of the tragus, when the bone conduction earphone receiver shell is worn, the side wall of the receiver shell main body can be tightly attached to the tragus, so that the attaching degree of the receiver shell main body and the front skeleton of a human ear is improved, the contact area of the receiver shell main body and the front skeleton of the human ear is increased, and effective transmission of vibration signals is guaranteed; the terminal surface that is used for attached people's face in the receiver shell main part is equipped with flexible skin, can improve the comfort level of receiver shell and the laminating of the anterior cheek of people's ear, and the hardness of the first contact zone that borders on the setting of indent cambered surface is less than the hardness of the second contact zone of keeping away from the setting of indent cambered surface because first contact zone direct laminating tragus, and lower hardness can reduce the oppression sense of receiver shell antitragus to the comfort level of wearing further promotes.
