An exemplary earphone includes a shell, a speaker received in the shell, and a wire electrically connecting with the speaker. The shell defines a sound cavity and a wire passage therein. The sound cavity and the wire passage communicate with each other. The speaker is received in the sound cavity. The wire is inserted into the sound cavity through the wire passage. An adhesive tape is wound around part of the wire. The adhesive tape abuts against an inner wall of the wire passage thereby fixing the wire in the wire passage.
