Abstract

An earphone device having composite functions at least has an earphone shell body, a loudspeaker, and an adjustment component. Several outer sound holes are disposed on the outer side of the earphone shell body. The loudspeaker is fixed in the earphone shell body. The loudspeaker is arranged outwards. The adjustment component is disposed on the earphone shell body. There are several adjustment holes corresponding to the outer sound holes of the earphone shell body on the adjustment component. The adjustment holes of the adjustment component can be controlled to be opposite to or be staggered with the outer sound holes of the earphone shell body. The earphone device is comfortable for use and can reduce pathological changes in ear and hearing decay to keep the human body healthy. Moreover, the earphone device has the functions of earphone, sound amplifier, and sound box.
