Abstract
The present disclosure relates to an earphone socket, an earphone plug, an earphone and an electronic device. For example, the earphone socket may include a socket body in which an earphone jack is formed. The earphone socket may include multiple ground terminals, which may be arranged in the earphone jack. The ground terminals may contact a ground section disposed on an earphone plug when the earphone plug is inserted into the earphone jack. The technical solutions of the present disclosure reduce earphone crosstalk and improve tone quality.
