Abstract

L'invention concerne un bouchon d'oreille composé d'un corps en élastomère souple, tel qu'une mousse résiliente, destiné à être inséré dans le conduit auditif, et d'un raidisseur en matériau plus rigide que le corps. En forme de tube et non pas de tige pleine, le raidisseur est à la fois résistant à l'affaissement dans l'axe et aisé à comprimer radialement pour faciliter la compression du corps lors de son introduction dans le conduit auditif. Le tube raidisseur peut être rempli de matériau en mousse résiliente pour bloquer le passage du bruit à travers le tube. Ce raidisseur tubulaire peut comporter une fente s'étendant parallèlement au raidisseur pris dans sa longueur, cette fente servant au remplissage du tube avec de la mousse souple, la mousse entourant le tube étant moulée. Ce moulage peut être réalisé par extrusion de mousse pendant le passage du raidisseur tubulaire avec la mousse à travers une tête d'extrusion.
