摘要： An earphone capable of reducing pressure in the ear canal and providing enhanced sound quality is provided along with a method for making the same. The earphone includes an earphone body penetrated by an air channel and having a receiving space receiving a vibrating membrane. A loudspeaker is provided in the receiving space and corresponds to the vibrating membrane. When the earphone is worn in the ear, the ear canal is in communication with the outside through the air channel so that acoustic waves generated by the vibrating membrane and reflected by the eardrum can propagate out of, rather than back and forth within, the ear canal. Thus, the eardrum is safe from an abnormal pressure otherwise attributable to repeatedly reflected acoustic waves, and the vibrating membrane is protected from a compressive force that may otherwise result from reflected acoustic waves and cause sound distortion.
