Fig. 1 is a kind of schematic cross-section of thermally conductive loudspeaker of air-pump type, including T iron；
Fig. 2 is the external structure schematic diagram of T iron shown in FIG. 1.
In figure: 11, T iron；111, through-hole；12, magnet steel；13, washer；14, frame；15, play wave；16, voice coil；17, cone；
18, dust cap.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1 and Fig. 2, in the present embodiment, a kind of thermally conductive loudspeaker of air-pump type of the utility model includes T
Iron 11, washer 13, frame 14, plays wave 15, voice coil 16, cone 17 and dust cap 18 at magnet steel 12；The T iron 11, the magnet steel
12, the washer 13 and frame 14 form magnetic circuit system, the bullet wave 15, the voice coil 16, the cone 17 and described dust-proof
Cap 18 forms vibrational system；The T iron 11, the magnet steel 12, the washer 13 and frame 14 are set gradually (herein from top to bottom
And aftermentioned "upper", "lower", "front", "rear" are relative position, not absolute definition, while when can be understood as overturning above
Become following)；The T iron 11 run through the magnet steel 12 and the washer 13, the T iron 11 respectively with the magnet steel 12, institute
