Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a TWS earphone device of making an uproar falls in automatic control physics, including earphone casing 1, be connected with speaker 13 on earphone casing 1, the outside cover of acoustic transmission section of thick bamboo of speaker 13 is equipped with earmuff 2, earphone casing 1's inside is equipped with control module 4, control module 4 includes bluetooth module 5, treater 6 and power management circuit 8, wherein, treater 6 is connected with bluetooth module 5 and power management circuit 8 respectively, bluetooth module 5 and speaker 13 are connected, the hollow type structure in earmuff 2, the inside of earmuff 2 is equipped with pressure sensor 7, pressure sensor 7 is connected with treater 6, earphone casing 1's inside still is equipped with miniature air pump 3, the output and the earmuff 2 intercommunication of miniature air pump 3, miniature air pump 3 is connected with treater 6.

Specifically, the connecting end of the earmuff 2 is connected with a base, the pressure sensor 7 is installed in the base, and the base is an engineering plastic ABS resin component.

Through adopting above-mentioned technical scheme, the base uses engineering plastics ABS resin one shot forming to come out, guarantees earmuff 2's leakproofness and durability.

Specifically, the ear cap 2 is a natural rubber latex member.
