Detailed Description

Examples

As shown in fig. 1 and 2, the present embodiment provides a sound-proof earphone comprising two earplugs 1 each made of a material having a slow rebound, i.e., a material having a slow deformation ability, which is deformed by an external force and then slowly returns to its original shape. Namely, the material has the characteristics of viscosity and elasticity, absorbs impact kinetic energy, can be repeatedly used and cannot be permanently deformed. Because the material obviously having slow rebound performance is represented by polyurethane slow rebound memory sponge, slow rebound is usually particularly memory sponge, and can be divided into polyether foaming series and MDI molding series according to different processes.

The inside chamber that holds that is equipped with of earplug 1, it is equipped with pronunciation module 2 to hold the intracavity, pronunciation module 2 can set up to wired sound production or wireless sound production, and the duct end of earplug 1 has been seted up and has been led sound hole 3, lead sound hole 3 and hold the chamber intercommunication. Earplug 1 is made by the material that kick-backs slowly, and earplug 1 can wrap up pronunciation module 2 in completely, and earplug 1's shape can be common conical, and its one end is the ear canal end, and the other end is external ear end, inserts the ear canal end of earplug 1 to the ear hole during the use, and the sound that pronunciation module 2 sent is through leading in sound hole 3 gets into human ear.

The utility model discloses in the use, hold between the fingers earplug 1 hard, conveniently put into the ear hole, when loosening the hand, the material of kick-backing slowly can kick-back slowly. After the earplug 1 is placed in the ear hole, the slow rebound material can be slowly restored, the ear hole is gradually filled and is tightly attached to the ear hole, and the sound insulation effect is achieved. The utility model discloses simple structure, convenient to use wears comfortablely moreover, and it is effectual to give sound insulation, and the user can not be disturbed by external sound when listening sound, can obtain better experience.

In an exemplary embodiment, the pronunciation module 2 includes a support tube and a speaker unit, the support tube is disposed in the accommodating cavity, the speaker unit is disposed inside the support tube, the speaker unit is connected with an earphone cable extending to the outside of the earplug 1, and the earplug 1 is provided with a wire hole 4 adapted to the earphone cable.
