Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
The profile of the woofer structure that Fig. 2 provides for the present embodiment, as in figure 2 it is shown, this woofer includes: frame 2 and be housed in the magnetic circuit system within frame 2 and vibrational system；
Magnetic circuit system is the toroid that U ferrum 6, cylindrical magnetic iron the 5, first washer 41 and the second washer 42 are formed, and wherein the first washer 41 and the second washer 42 constitute the magnetic circuit gap of annular；
Concrete, with reference to shown in Fig. 2, U ferrum 6 includes that groove and sidewall, the first washer 41 include annular fixed part 411 and annular extension 412, and the second washer 42 is cylindricality washer；Cylindrical magnetic iron 5 is arranged on the center of groove, second washer 42 is arranged on cylindrical magnetic iron 5, the diameter of the second washer 42 is slightly larger than the diameter of cylindrical magnetic iron 5, the annular fixed part 411 of the first washer 41 is arranged on the sidewall of U ferrum 6, thus the first washer 41 is fixed on U ferrum 6, the annular extension 412 of the first washer 41 and the second washer 42 constitute the magnetic circuit gap of annular；I.e. U ferrum 6, cylindrical magnetic iron the 5, first washer 41 and the second washer 42 form a toroid.
Vibrational system in Fig. 2 includes: vibrating diaphragm 1, voice coil loudspeaker voice coil 3 and the bullet ripple 7 being placed in toroid, voice coil loudspeaker voice coil 3 is fixed on vibrating diaphragm 1 by the top of its winding section, and be suspended in the magnetic circuit gap of annular, the outer end playing ripple 7 is fixed on the medial wall of U ferrum 6, and the inner is bonded in the bottom of voice coil loudspeaker voice coil 3 winding section.
After powered up, voice coil loudspeaker voice coil 3 stress in magnetic field, drive vibrating diaphragm 1 vibrates woofer in Fig. 2, produces sound, plays ripple 7 and makes voice coil loudspeaker voice coil 3 move in magnetic gap, will not encounter the first washer 41 and the second washer 42 and cause wiping circle.
