A speaker system, comprising:

• a first housing, wherein a first accommodating cavity is arranged inside the first housing;
• a first active vibrating diaphragm, wherein the first active vibrating diaphragm is arranged inside the first accommodating cavity;
• a second housing, wherein a second accommodating cavity is arranged inside the second housing, and the second accommodating cavity is communicated with the first accommodating cavity to form a closed cavity;
• a first passive vibrating diaphragm, wherein the first passive vibrating diaphragm is arranged on one side of the second housing and is driven by the first active vibrating diaphragm to vibrate;
• and
• at least one second passive vibrating diaphragm, wherein the second passive vibrating diaphragm is arranged on one side of the second housing facing away from the first passive vibrating diaphragm, and a vibration starting direction of the second passive vibrating diaphragm and a vibration starting direction of the first passive vibrating diaphragm are opposite;
• and/or, the second passive vibrating diaphragm and the first passive vibrating diaphragm are arranged on the same side of the second housing, and a vibration starting direction of the second passive vibrating diaphragm and a vibration starting direction of the first passive vibrating diaphragm are the same.
