As the utility model, further scheme, the shell left side are provided with noise reduction layer, are arranged in the noise reduction layer There are several bloops.

As the utility model, further scheme, the silencing block are several layers silencing cotton and acoustical cotton cooperation overlapping system At.

As the utility model, further scheme, the ear-hang are to be rotatably connected with installation base.

As the utility model, further scheme, the ear-hang end are provided with rounded structure.

As the utility model further scheme, annular umbrella-like elastic slice is provided on the silica gel sheath.

As the utility model, further scheme, the annular umbrella-like elastic slice quantity are 3.

As the utility model, further scheme, annular umbrella-like elastic slice thickness are no more than 1mm.

As the utility model, further scheme, the fitting block are hollow cystic structures.

The utility model obtain the utility model has the advantages that

1, it is used cooperatively using annular umbrella-like elastic slice, fitting block, ear-hang, it is convenient to wear, it is not easily to fall off.

2, silica gel sheath is to be socketed on shell, can be removed, easy to clean to avoid bacterium infection, while can for individual difference Various sizes of silica gel sheath replacement is provided.

3, silencing block is used cooperatively using acoustical cotton and silencing cotton, and noise control sound effective value is more preferable.
