Abstract: A method for controlling a multi-mover direct drive transmission system and related devices, including: S1: detecting a real-time position of the mover units movable in the feedback segments; S2: determining whether the mover unit enters junction region between the feedback and transition segments: if yes, calculating, by using preset algorithm, an electrical angle at which the mover unit moves in the transition segment, and determining real-time position of the mover unit through the electrical angle; and setting cooperative control mode of the stator windings in a range of the transition segment according to the real-time position of the mover unit; and S3: determining whether the mover unit enters the junction region between the transition segment and the feedback segment: if yes, feeding back real-time position of the mover unit through the displacement sensor of the feedback segment. The above solution has a good control effect, low costs, and low mounting requirements.

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.
