Ear tip including flange made of silicone foam material

An ear tip having a flange made of silicone foam, the ear tip comprising a central core and a flange surrounding the core, wherein the flange is made of silicone foam, and the core is made of a material harder than the silicone foam,

• wherein:
• the core includes an upper wall formed above a mesh slot in which a mesh is mounted, and a lower part integrated with the upper wall, formed below the mesh slot, and provided with a horizontal portion protruding inward and a vertical portion extending downward from the horizontal portion in an integrated form, and a base including a hook-shaped protrusion protruding inward is formed below the lower part;
• and
• the flange is manufactured in a structure that covers the overall core except for a bottom surface of the core, the flange includes a sound emission hole extending above the upper wall, a flange upper wall configured to come into close contact with and completely cover an outer surface of the upper wall, and a flange lower wall extending below the flange upper wall to the bottom surface of the core and covering an outer side surface of the lower part, the flange lower wall has a thinner thickness than the flange upper wall, and a dome portion extending further below the flange lower wall while expanding outward from a side surface of the flange upper wall is formed around the flange upper wall and the flange lower wall,
• wherein a space is formed between the flange lower wall and the dome portion, and a lower edge provided by the dome portion and extending further below a bottom surface of the flange lower wall provides a space below the bottom surface of the flange lower wall, which facilitates deformation of the flange when the ear tip is worn.
