  • Patent number: 12212916
    Abstract: The present disclosure provides a headphone including a sound production component and an ear hook. The ear hook and the sound production component form a first projection on a user's sagittal plane. In a non-wearing state, an inner contour, a first end contour, a second end contour of the first projection, and a tangent segment connecting the first end contour and the second end contour jointly define a first closed curve. A first area of the first closed curve ranges 300 mm2-500 mm2. A portion of the inner contour corresponding to the ear hook includes a first curve. The first curve has an extremum point in a first direction perpendicular to a long axis direction of a projection of the sound production component, the extremum point is located behind a projection point of an upper vertex of the ear hook on the sagittal plane.
