Earphone

Abstract

The invention discloses an earphone, which comprises a sound production part, an abutting part and an ear hook, and is characterized in that the ear hook is connected with the sound production part and the abutting part, the ear hook is provided with a symmetric surface arranged along the length direction of the ear hook, and the abutting part comprises a first shell and a first microphone arranged in the first shell; the sound production part comprises a second shell and a second microphone arranged in the second shell, the earphone further comprises a processing circuit for carrying out noise reduction processing based on the first sound and the second sound, and the earphone further comprises a first reference plane which is located below the symmetry plane and is parallel to the symmetry plane in a wearing state; the distance between the first reference plane and the symmetry plane is smaller than or equal to 5 mm, the first sound inlet hole is provided with a sound inlet end located on the outer wall face of the first shell, and the whole sound inlet end is located on the side, facing the symmetry plane, of the first reference plane. In this way, the noise reduction effect of the processing circuit can be improved, and the sound receiving effect of the earphone can be improved.
