Abstract
A speaker includes a shell, a magnetic circuit unit, and a vibration unit. The magnetic circuit unit includes a yoke and a magnet. The yoke includes a bottom wall connected to the magnet. The bottom wall includes an upper surface close to the vibration unit, and a lower surface opposite to the upper surface. A first groove and a second groove that are spaced apart from each other are formed on the upper surface by recessing towards the lower surface. An orthographic projection of the magnet on the upper surface along a vibrating direction of the vibration unit completely covers the first groove. The second groove is arranged outside the orthographic projection. The magnet and the bottom wall are glued and connected by a glue. The glue is received in the first groove. In the speaker, the magnet is firmly connected and is unlikely to be detached.
