An ear pad, wherein a large number of rib-like sound proof walls (12) formed of the same material as that of a body (11) formed in a hollow cylindrical shape with an elastic material, i.e., a rubber such as silicon rubber and a soft synthetic resin such as polypropylene are provided on the outer peripheral surface of the body integrally with each other in ring shape at specified intervals in axial direction, whereby soft mountability not irritating the sensitive tactile of an external acoustic meatus can be provided to the ear pad.

Cette invention se rapporte à une oreillette, dans laquelle un grand nombre de parois isophoniques en forme de nervures (12) formées dans le même matériau qu'un corps (11) de forme cylindrique creuse en un matériau élastique, c'est-à-dire un caoutchouc tel que du caoutchouc de silicium, et une résine synthétique souple telle que du polypropylène, sont formées sur la surface périphérique externe dudit corps de façon solidaire entre eux, en forme d'anneau à intervalles spécifiés dans le sens axial, ce qui permet de placer l'oreillette de façon souple dans l'oreille sans irriter la surface sensible au toucher du conduit auditif externe.
