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. 1-6, the present invention is a protecting cover for preventing the sound membrane deformation of a receiver in an in-ear earphone, including an earphone main body 2 and a sound output main body 9, wherein a sound receiving case 1 is fixed on the top of the earphone main body 2, a sealed cavity is disposed inside the sound receiving case 1, and a sound output mechanism for generating sound is disposed inside the earphone main body 2;

here, the earplugs 3 are arranged on the outer side of the bottom end of the earphone main body 2, and the earplugs 3 are made of silica gel, so that the earplugs 3 made of silica gel prevent ears of a user from being injured;

the sound outlet mechanism consists of a fixed shell 4, a limiting protecting cover 5 and a sound film 6, a sound outlet main body 9 is fixed at the top end inside the fixed shell 4, a protecting shell 7 is fixed inside the fixed shell 4 and outside the bottom of the sound outlet main body 9, a gasket 8 is fixed inside the fixed shell 4 and at the bottom end of the sound outlet main body 9, so that the sound outlet main body 9 can be fixed more stably, the sound film 6 is fixed at the bottom end inside the fixed shell 4, the limiting protecting cover 5 is fixed inside the fixed shell 4 and at the bottom end of the sound film 6, and therefore deformation that the sound film 6 cannot be restored due to air pressure difference of an earphone cavity is effectively solved through the limiting protecting cover 5;
