Eartip, mold device for manufacturing the eartip, and method of manufacturing the eartip

摘要

An eartip, mold device for manufacturing the eartip, and method of manufacturing the eartip are introduced, characterized by forming an upper bevel-portion with upper and lower molds of a first mold unit, placing the upper bevel-portion in an upper bevel receiving cavity of a second mold unit, forming a lower bevel-portion with a lower bevel cavity, and joining the upper and lower bevel-portions to form an eartip. The top of the lower hollow-cored guiding tube extends to form a buffer portion which connects and communicates with the upper hollow-cored guiding tube. The upper and lower bevel-portions are made of silicone of different rigidity. The upper bevel-portion thus made is soft enough to reach a user's ear canal deeply. The lower bevel-portion thus made is rigid enough to close the ear canal. An annular buffer cavity is inwardly, concavely formed at the bottom of the lower bevel cavity.
