Abstract
The present application provides a speaker. The magnetic circuit system of the speaker includes a lower clamping plate fixed to a base frame, a center magnetic circuit fixed to the lower clamping plate, and a side magnetic circuit provided around the center magnetic circuit to form a magnetic gap. The side magnetic circuit includes two symmetrically spaced first side magnetic units; each first side magnetic unit includes a first side magnet, a first side pole core, and a second side magnet. The first side magnet and/or the second side magnet include a first main body and a first projection, and a first grooving is formed by the first body portion and the first projection, so that an occupied space for the side magnets can be reduced, which allows for maximizing the volume of the magnet while fully utilizing the vibration space to enhance magnetic force.
