EAR TIP AND METHOD OF MANUFACTURING THE SAME AND EAR PHONE INCLUDING THE SAME

摘要

In an ear tip and a method of manufacturing the same, the ear tip includes a sound transfer part including a hollow shaft and an external sheet and an acoustic absorbent making contact with the external sheet and the hollow shaft. The hollow shaft has a cylindrical shape of which a circumferential surface is flat and provides a sound conduit for transferring audio signals. The external sheet is extended from an end portion of the hollow shaft in such a way that the hollow shaft is enclosed with the external sheet and a gap space is provided between the external sheet and the hollow shaft. The acoustic absorbent is positioned in the gap space and has a plurality of pores, thereby absorbing surrounding noises and preventing the surrounding noises from transferring into user's ear.
