    摘要: 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.

    摘要: [Problem]
    Provided is a high-performance and high-quality curved diaphragm speaker system that is capable of reproducing sounds in a plurality of bands and achieves performance sufficient for hard-of-hearing people and hearing people.
    [Solution]
    A speaker unit 10 of the present invention includes a first diaphragm 1 in a corn form, a second diaphragm 2 in a curved sheet form, and a driver unit 4 that drives both of the first diaphragm and the second diaphragm. A small diameter side 1a of the first diaphragm and one end side 2a of the second diaphragm are both connected to the driver unit. The second diaphragm has a plurality of regions having different resonance characteristics due to a change in the curvature of a diaphragm surface in the middle from the one end side to the other end side in a length direction. This speaker unit is attached to a housing 50 to form a speaker 100.
