Speaker

A speaker, comprising a frame, a vibration system fixed to the frame, and a magnetic circuit system with a magnetic gap,

• wherein the vibration system comprises a first diaphragm and a second diaphragm which are fixed to two opposite sides of the frame, a first voice coil assembly inserted into the magnetic gap to drive the first diaphragm to vibrate and produce sounds, and a second voice coil assembly inserted into the magnetic gap to drive the second diaphragm to vibrate and produce sounds;
• the first diaphragm comprises a first dome located in the center, a first curved ring which surrounds the first dome and fixed to the frame, and a first dome connecting wall formed by extending from the first dome towards the first voice coil assembly;
• the second diaphragm comprises a second dome located in the center, a second curved ring which surrounds the second dome and is fixed to the frame, and a second dome connecting wall formed by extending from the second dome towards the second voice coil assembly;
• the first dome and the first dome connecting wall, and the second dome and the second dome connecting wall are integrated respectively;
• the vibration system further comprises a first elastic wave assembly and a second elastic wave assembly which are fixed to the frame and are spaced from each other;
• one end of the first elastic wave assembly away from the frame is connected to the first dome connecting wall;
• one end of the second elastic wave assembly away from the frame is connected to the second dome connecting wall;
• and the first elastic wave assembly and the second elastic wave assembly are in staggered distribution and antiphase vibration.
