Wearable electronic devices with magnetic switches

A wearable electronic device that is designed to be worn on the head of a user comprising:

• an electrical sound speaker;
• a magnetic switch that has a hysteresis input-output relationship in which the magnetic switch is turned on when the magnitude of the magnetic field (Bi) detected by the magnetic switch is greater than a manufacturer defined upper threshold value (BH), the magnetic switch is turned off when the magnitude of the magnetic field (Bi) detected by the magnetic switch is less than a manufacturer defined lower threshold value (BL) where BL is less than BH, the magnetic switch remains on when it is switched on until Bi becomes less than BL, and the magnetic switch remains off when it is switched off until Bi becomes greater than BH;
• and
• a waterproof package that encloses the magnetic switch, where such waterproof package satisfies the IPX7 water resistance standard, meaning that such waterproof package can remain submerged in one-meter deep water for 30 minutes without enduring damages to the electrical components enclosed by the waterproof package,
• wherein the wearable electronic device can use the output of the magnetic switch to determine whether to pause or to play the music played by the electrical sound speaker.
