Abstract: The vibrator comprises a vibration block, and the vibration block comprises at least one permanent magnet, the stator comprises conductive blocks, and the conductive blocks are subjected to the effect of a magnetic field force which is the same as and/or opposite to the vibration direction of the vibrator. When the vibrator is in a balanced state, the resultant force of the magnetic field force is zero. When the magnetic conductive blocks are subjected to the effect of an excitation force to perform a relative displacement relative to the vibrator in the vibration direction of the vibrator, a direction of the resultant force of the magnetic field forces is the same as the direction of the relative displacement, a magnitude of the resultant force of the magnetic field forces has a proportional relationship with a magnitude of the relative displacement. The conductive blocks are used to replace the stator coils.

Abstract: A wireless earphone comprising an in-ear portion which is in contact with a human ear when the wireless earphone is worn. The in-ear portion comprises a wearing surface which couples the human ear canal when the wireless earphone is worn. The in-ear portion is provided with a wearing detection sensor, a sound venting hole and a contact group which are all disposed on the wearing surface. The wearing detection sensor, the sound venting hole and the contact group are all disposed on the wearing surface of the in-ear portion coupling the human ear canal, so that the wearing detection sensor can directly contact the skin of the human body when the earphone is worn, and thus the wearing detection sensor is improved.
