Abstract

The utility model relates to a left-and-right anti-misconnection concave-convex structure of a magnetic connector of a magnetic connecting headphone. The left-and-right anti-misconnection concave-convex structures comprise an audio connecting end, a first headphone end and a second headphone end, wherein one end of an audio input end housing A is a concave end of the anti-misconnection concave-convex structure; one end of a first headphone end housing B is a concave end of the anti-misconnection concave-convex structure; the other end of the first headphone end housing B is a convex end of the anti-misconnection concave-convex structure; and one end of a second headphone end housing C is a convex end of the anti-misconnection concave-convex structure. By virtue of matched abutting of the anti-misconnection concave-convex structure between the audio input end and the first headphone end and between the first headphone end and the second headphone end, the volume of the magnetic connector is reduced; as a needle-shaped probe is used as an electrode of the magnetic connector, the external diameter of the connector is reduced; and through the adoption of the concave-convex structure, the end misconnection is prevented, so that the size of the magnetic connecting headphone is reduced.
