Abstract: A single-magnet double-tone-circuit coaxial loudspeaker includes a shell, a U iron, a magnet, a spring washer, a first diaphragm assembly, a second diaphragm assembly, an upper cover and a terminal plate. A single “magnet+spring washer+U iron” magnetic circuit is extended to be two upper-lower coaxial magnetic circuits, therefore, the first diaphragm assembly and the second diaphragm assembly which are electrically connected to the terminal plate generate a double-magnetic-circuit feature by sharing a single-magnet system. High frequency and low frequency wave bands are driven independently, such that high frequency and low frequency portions can achieve a better sound resolution effect. The complementation of the two reduces distortion, thus improves the overall acoustic performance of the loudspeaker.
