Abstract: A linear movement bistable electromagnetic switch, comprising a coil (1), a magnetic rotor (2) movably disposed in an inner hole of the coil (1), a shell (3) which wraps an outer side surface of the coil (1), and an insulating layer (4) disposed between the coil (1) and the shell (3). The magnetic rotor (2) is able to move under the effect of a magnetic field generated after the coil is energized; one end of the magnetic rotor (2) extends out of the coil (1) and is connected to a blocking piece (211) for opening/closing a loudspeaker leakage hole. The magnetic rotor is able to be extended or retracted by changing the direction of current in the coil so as to drive the blocking piece to block or open the leakage hole, such that the call distortion condition can be improved and the high-frequency sound effect will not be reduced.
