Kind Code:
A1
Abstract:
Provided is an ear muff (7) comprising a gasket (10), wherein the gasket (10) comprises an installation face (12) having two opposite sides; a covering member (20) comprising a plurality of installation parts (26) and a plurality of spacing parts (28) arranged at intervals, wherein the plurality of installation parts (26) are fixed to any side and the plurality of spacing parts (28) can be separated from the side; and a soft pad (30) covered within the covering member (20). In the process of deformation of the soft pad (30), air can enter and exit the covering member through the spacing parts of the covering member (20) which are not fixed to the installation face, thus aiding deformation of the soft pad. Therefore, the covering member does not need to be perforated, and the scrap rate thereof is reduced.
