Abstract
The present application relates to a sound production unit and a speaker. The sound production unit includes: a frame, where the frame has a receiving space; a magnetic path system, where the magnetic path system is arranged in the receiving space, and a magnetic gap is formed in the magnetic path system; a vibration system, where the vibration system includes a first diaphragm and a second, a first voice coil assembly inserted into the magnetic gap to drive the first diaphragm to vibrate to produce a sound, and a second voice coil assembly inserted into the magnetic gap to drive the second diaphragm to vibrate to produce a sound; and an end cover. Vibrations of the sound production unit or the speaker and the like can be counteracted; cophase stacking can also be performed on sound waves; and the acoustics effect of the speaker is enhanced.
