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 3):
An earphone, comprising: a housing, a first speaker unit, and a second speaker unit; wherein a sound guiding portion is disposed on the housing, and at least one sound guiding channel and an accommodating structure capable of accommodating the second speaker unit are respectively disposed in the sound guiding portion; wherein the sound guiding channel is located between the accommodating structure and an outer wall of the sound guiding portion, and a sound output hole of the sound guiding channel is located at an end face of the sound guiding portion away from the housing; wherein the accommodating structure partially protrudes from the sound output hole of the sound guiding channel, and a front end of the accommodating structure has a sound output hole; wherein the first speaker unit is arranged in the housing, and the second speaker unit is arranged in the accommodating structure; wherein the sound output direction of the second speaker unit is the same as the sound output direction of the sound guiding portion; wherein the sound waves generated by the first speaker unit directly pass through the sound output hole of the sound guiding channel, and the sound waves generated by the second speaker unit directly pass through the sound output hole of the accommodating structure.
