Abstract:
An earphone includes a housing, a speaker unit arranged in the housing, a sound guiding portion disposed on the housing, and a sound guiding tube disposed in the sound guiding portion such that an inner sound guiding channel and an outer sound guiding channel are formed in the sound guiding portion. The sound guiding portion has a sound output hole of the inner sound guiding channel and a sound output hole of the outer sound guiding channel. The sound output hole of the inner sound guiding channel protrudes from the sound output hole of the outer sound guiding channel. The sound waves in the inner sound guiding channel directly pass through the sound output hole of the inner sound guiding channel, and the sound waves in the outer sound guiding channel directly pass through the sound output hole of the outer sound guiding channel.

Claim (Index 4):
The earphone according to  claim 3 , wherein an outer wall of the accommodating structure has a ring-shaped inclined surface close to the sound output holes, the inclined surface is in front of the sound output hole of the sound guiding channel and is close to the sound output hole of the accommodating structure; wherein the inclined surface covers a part of the sound output direction of the sound output hole of the sound guiding channel such that a part of the sound waves outputted from the sound output hole of the sound guiding channel are directly outputted, and another part of the sound waves outputted from the sound output hole of the sound guiding channel are refracted by the inclined surface.
