Technical solution.
As shown in Figure 1-Figure 3, a kind of ring belt type coaxial loudspeaker of the present embodiment comprising shell 1 and setting exist
Ring belt type loudspeaking component 2 in shell 1, ring belt type loudspeaking component 2 include the outer ring magnet 21 of coaxial arrangement, annular
Magnet 22, annular diaphragm 23 and the first magnetic guiding loop 24, outer ring magnet 21 and annular magnet 22 are arranged concentrically or at least office
Portion is located in same sagittal plane, and the first magnetic guiding loop 24 and annular diaphragm 23 set up outer ring magnet 21 and annular magnet 22 separately
Axial inside and outside both sides, are arranged annular gap, annular diaphragm 23 is in its axial direction between outer ring magnet 21 and annular magnet 22
The part of corresponding annular gap is provided with spiral winding 25, and the first magnetic guiding loop 24 is accessibly connected outer ring magnet 21 and annular
Magnet 22.Coaxial specific two or more annular elements in the present embodiment are same axis；It is specially in same axis with one heart
On the basis of, the axle center of two or more annular elements is also identical；Be partially located in same sagittal plane is specially two or more
A annular element partially overlaps radially.
Shell 1 forms the sounding of the annular loudspeaking component of sound chamber cooperation for housing ring belt type loudspeaking component 2.Pass through
The conducting of outer ring magnet 21, annular magnet 22, annular diaphragm 23 and the first magnetic guiding loop 24, after the energization of spiral winding 25
Cutting outer ring magnet 21 and annular magnet 22 are formed by magnetic field to make 23 vibration sounding of annular diaphragm, spiral winding 25
