  • Publication number: 20070177748
    Abstract: An earphone structure comprises a housing body and a cover body combined therewith. A first speaker, a second speaker and a hood body are respectively combined to the inside and the outside of said cover body. The central axes of the first speaker and the second speaker are respectively pointed to a direction in which the lower end of the hood body is corresponding to an earhole of a user's ear. Whereby, when the user wears the earphone, the user's earhole can receive the largest amplitude of sound wave emitted from each speaker so as to obtain the best stereo sound effect.
