Document Type and Number:
WIPO Patent Application WO/2010/150931
Kind Code:
A1
Abstract:
The present invention relates to in-canal earphones inserted into ear canals. The present invention provides earphones which use speakers that output electric signals as sound signals and do not easily fall out of the ears due to ear pads that surround the surfaces which contact the canals when the speakers are inserted into the ear canals. Furthermore, the earphones do not cause pain because the ears are not pressed, and inconvenience felt as a result of the earphones being foreign matter is reduced. According to the present invention, the earphones are used while inserted into the ear canals when the user is sleeping or wearing a helmet fitted to the user's head, thereby reducing a feeling of irritation due to the earphones. Therefore, since the user's ears are not pressed even when the user wears the earphones for a long time, the earphones do not cause pain, and inconvenience is reduced since the earphones do not easily fall out as a result of the friction caused by contact of the inserted earphones with the surfaces of the ear canals. Consequently, the user is able to use the earphones conveniently.
