摘要： A magnetic circuit unit includes a yoke, a magnet positioned on the yoke, a plate on the magnet. The yoke includes a bottom defining a central hole therein, and a wall extending from the bottom. The magnet is positioned on the bottom of the yoke. The plate defines a base coupled to a top surface of the magnet, and a central pole extending from the base and getting through the annular magnet with an end thereof suspended in the central hole of the yoke. Thus, a first magnetic gap is formed between the wall of the yoke and an outer side of the annular magnet, and a second magnetic gap is formed between the central pole of the plate and an inner side of the annular magnet. A speaker using the magnetic circuit unit described above is disclosed.
