摘要：
1. A method of manufacturing an ear plug, comprising the steps of: covering an elongated core with an outer layer, wherein the elongated core contains a first material, and the outer layer contains a second material, and the second material contains an inactive foaming agent； at least a portion of the outer layer is located and an elongated core in the form and activate a foaming agent in at least a portion of the outer layer to form a silencing portion and a leg bonded to the elongated core. 2. The method according to claim 1, characterized in that the noise suppression part has a first average density ρ, and the leg has a second average density ρ, and ρ>； 1.2ρ.3. The method according to claim 1, characterized in that the noise suppression part has a first average density ρ and the foot has a second average density ρ, and ρ>； 1.5 ρ4. The method according to claim 1, characterized in that the form contains a first cavity restricting the expansion of the outer layer. The method according to claim 4, characterized in that the first cavity has the shape of a noise suppressing part. A method according to claim 4, characterized in that the form further comprises a second cavity having the shape of a leg. A method according to claim 6, characterized in that at least part of the activation step of the foaming agent is performed when the first cavity is located below the second cavity. The method according to claim 1, characterized in that the step of activating the foaming agent comprises applying heat to at least a portion of the outer layer. The method according to claim 1, characterized in that it further comprises the step of extruding the first material to form an elongated core from it. The method of claim 1, wherein the step of coating the elongated core comprises a step selected from the group consisting of1.
