EAR TIP FORMING ACOUSTIC ABSORBENT COMPRISING SILICON FOAM IN A SPACE BETWEEN OUTER SKINS, A MANUFACTURING METHOD THEREOF, AND EARPHONE HAVING EAR TIP

摘要

PURPOSE: An ear tip, a manufacturing method thereof, and an earphone having the ear tip are manufactured through processes omitting a process of combining separated manufactured sound absorbent and ear tip.;CONSTITUTION: An ear tip (500) comprises a waveguide unit (100) and an acoustic absorbing unit (200). The waveguide unit includes a hollow shaft (110) and an outer skin (120). The hollow shaft having a cylinder shape comprising a plane cylindrical surface provides sound waves transmitting sounds. The outer skin is extended from one end of the hollow shaft and surrounds the hollow shaft to form a space. The acoustic absorbing unit includes porous materials and prevents noise from the outside by inserting the acoustic absorbing unit into the space.;COPYRIGHT KIPO 2013
