The present invention relates to an open type earphone, and more specifically, to the open type earphone which protects ears by forming a structure where a sound wavelength is delivered to the ear secondly via the air by mitigating pressure firstly by dispersing and diffusing sound emitted from a speaker to the air. According to an embodiment of the present invention, the earphone comprises: a housing which is formed with one side inserted into the ear of a user and is embedded at one side for a speaker to be toward the inside of the ear; a connection electric wire for delivering an electrical signal; and a connection jack thereof. The housing has a shielding wall which is closed by dividing an inner space with an empty cylindrical shape, and is divided into an open part and a closed part across the shielding wall. An outer end of the open part is protruded with a cross section smaller than a cross section of the open part to form an insertion part, and an ear cap is inserted into the outside of the insertion part. A speaker is combined to an outer end of the shielded part toward the outside. |
