Abstract
A coaxial speaker is disclosed. The coaxial speaker includes a magnetic circuit system and two sounding units. The magnetic circuit system includes a ring magnetic unit, a magnet and a yoke arranged on an outer side of the ring magnetic unit, and a first ring magnet sleeved on an insert inserted into an inner side of the ring magnetic unit. Magnetic polarities of the inner and outer surfaces of the first ring magnet are opposite. The first ring magnet together with the ring magnetic unit forms a first magnetic gap for one sounding unit. The ring magnetic unit together with the magnet and the yoke forms a second magnetic gap for another sounding unit. Diaphragms of the two sounding units are fixed to the ring magnetic unit. The coaxial speaker improves the low-frequency performance.
