Loudspeaker and electronic equipment

The embodiment of the invention provides a loudspeaker and electronic equipment, and the loudspeaker comprises a first vibration system, a second vibration system and a magnetic circuit system, the first vibration system is located at a first side of the magnetic circuit system, the second vibration system is located at a second side of the magnetic circuit system, and the magnetic circuit system is configured to provide a magnetic source for the first vibration system and the second vibration system to vibrate. The first vibration system and the magnetic circuit system form a first sound production unit, and the second vibration system and the magnetic circuit system form a second sound production unit; the magnetism of the opposite parts of the first side and the second side in the thickness direction is opposite, and the working frequency bands of the first sound production unit and the second sound production unit are different, so that the first vibration system and the second vibration system can vibrat
