End face, the first column, abutting part, the second column and round platform portion are sequentially arranged along first direction；Abutting part connects lid, and filtering part is fixed
In in the first column.
By said program as it can be seen that the filtering part being fixed in the first column can be filtered extraneous high frequency noise decaying, and
The sound wave of middle low frequency then enters human antrum auris, to enable user that can also be carried out with other people while avoiding receiving high frequency noise
Smoothly link up.
Further embodiment is that the quantity in arcs portion is three.
Further embodiment is that lid includes fixed column, and fixed column is protruded into along first direction in the first column.
Further embodiment is that fixing piece includes tone channel, goes out tone channel and runs through round platform portion and the second column.
Further embodiment is to filter the material of part as glass fiber cotton.
To realize that above-mentioned second purpose, filter provided by the utility model include lid, fixing piece and filtering part, fix
Part includes the round platform portion being connected with each other and cylindrical portion, is first party from the axis that cylindrical portion is directed toward round platform portion and is parallel to cylindrical portion
To, cylindrical portion outer wall is surrounded with abutting part, and round platform portion includes the first column and the second column, and the first column includes multiple arcs portions,
Multiple arcs portions are along the circumferentially disposed in the end face of the first column of the first column, and the first column, abutting part, the second column and round platform portion are along first
Direction is sequentially arranged；Abutting part connects lid, and filtering part is fixed in the first column.
By said program as it can be seen that the filtering part being fixed in the first column can be filtered extraneous high frequency noise decaying, and
The sound wave of middle low frequency then enters human antrum auris, to enable user that can also be carried out with other people while avoiding receiving high frequency noise
Smoothly link up.
Further embodiment is that the quantity in arcs portion is three.
Further embodiment is that lid includes fixed column, and fixed column is protruded into along first direction in the first column.
Further embodiment is that fixing piece includes tone channel, goes out tone channel and runs through round platform portion and the second column.
Further embodiment is to filter the material of part as glass fiber cotton.
Description of the drawings
