摘要： An open-air type earphone having a duct that communicates between an inside and an outside of the earphone and applies an inductance component to an acoustic signal generated by an electroacoustic transducer. The earphone includes the electroacoustic transducer to convert an electric signal into an acoustic signal, a housing to accommodate the electroacoustic transducer, and a variable duct unit that inwardly extends from the housing to communicate between the earphone and the surrounding atmosphere, and to adjust an inductance component for the acoustic signal generated by the electroacoustic transducer. Since a length or sectional area of the duct can be varied at an end of the housing, a frequency characteristics, particularly, a loss bass characteristic of the earphone, can be easily adjusted according to a user's taste, a genre of music, and the like.
