Coaxial loudspeaker and an external resolving diaphragm (21) operate in a low frequency range.An internal baffle (23) functions in a higher frequency range, and the recognition of the two speakers is in a common frame (10);A diaphragm (21) connected with an external coil (22) voice and an external connection, an internal voice coil (24) connected, and two coaxial axes of an internal partition (23) Concentrated magnets (31A ferrite core associated with a ferrite (32), 41, 42, 43) extends between a voice coil (22, 24) and a gap (51, 52).The flexible suspension element (11~14) is connected with the diaphragm (10) under the impact of the horn.In the proposed speaker, an inner core (41) and an outer core (42) are separated from each other by an internal air gap (52).An external magnet (31) is detected and an internal magnet (32) is detected.A core ferrite (43a) external magnet (31) separates the outer air gap (51) from the outer core (42), but it is between the two. Gamma ray;The outer diaphragm (21) of the voice coil (22) extends to the outer air gap (51) and the inner part of the voice coil (24) extends to the bulkhead (23). Indoor air gap (52).
