Embodiment 1
[0028] Such as figure 1 and figure 2 Commonly shown, a loudspeaker includes a ring-shaped casing 10 , and a vibration system 20 and a magnetic circuit system 30 are accommodated in the casing 10 .
[0029] Such as figure 1 and figure 2 Commonly shown, the vibrating system 20 includes a voice coil, and the voice coil includes a cylindrical frame and a coil 260 wound on one end of the frame close to the magnetic circuit system 30 . The vibrating system 20 also includes a ring 24 whose inner edge is fixed on the skeleton, and whose outer edge is fixed on the upper surface of the shell 10 , and the ring 24 is located above the coil 260 . The vibrating system 20 also includes a DOME 22 covering the upper end of the skeleton, and the edge portion of the DOME 22 is fixed on the skeleton.
[0030] Such as figure 1 , figure 2 and image 3 Commonly shown, the skeleton includes a first skeleton 264 and a second skeleton 262 spliced together up and down, the first skeleton 264...
Embodiment 2
[0035] This embodiment is basically the same as Embodiment 1, the difference is that:
[0036] The magnetically permeable part is a T-iron, ring-shaped magnets and washers are sequentially fixed on the edge of the T-iron, and a magnetic gap is provided between the magnet, the washers and the central column of the T-iron. The washer is fixed on the inner wall of the casing, and the upper surface of the washer is fixedly combined with the lower surface of the positioning boss.
[0037] The skeleton of the loudspeaker of the present invention is composed of two parts of the skeleton superimposed up and down, and the inner edge of the ring is clamped and fixed between the two parts of the skeleton, which plays a role of positioning and blocking when the ring is bonded, thereby effectively improving The consistency of the speaker is improved, and the influence of the nonlinearity of the speaker due to glue leakage is also prevented, and the acoustic performance of the speaker is im...
