Embodiment
Below in conjunction with drawings and Examples the utility model is further specified (but not being to restriction of the present utility model).
The technical scheme that burglar alarm voice loudspeaker of the present utility model are adopted is: described burglar alarm voice loudspeaker comprise enamel-cover voice coil loudspeaker voice coil, cone, retaining washer, poly-sound chamber, resonant cavity, magnetic cylinder, bottom etc.; Its shape as shown in drawings.As shown in figure 10, described enamel-cover voice coil loudspeaker voice coil 1 is wound with enameled wire loop, and the enamel-cover voice coil loudspeaker voice coil is adhesive in the garden of the recessed one side of cone 2 on week, is assembled into the pronunciation moving-coil with cone.Retaining washer 3 is arranged outside the enamel-cover voice coil loudspeaker voice coil, and retaining washer is provided with fairlead and binding post, and the lead-out wire of enameled wire loop passes the retaining washer fairlead, is fixed on the binding post, and links to each other with external electrical outlet lead.As shown in figure 13, described magnetic cylinder 4 middle devices have the magnet 5 of a flat Cylinder, be provided with gap 6 between the magnetic cylinder of the flat Cylinder of magnet and device magnet, as shown in figure 16, the coil of the enamel-cover voice coil loudspeaker voice coil of the hollow Cylinder of papery insert magnet flat Cylinder and the device magnet the magnetic cylinder between gap 6 in; Poly-sound chamber 7 tightly is enclosed within the one side of cone 2 projectioies.The magnetic cylinder, poly-sound chamber, correspondence position on the cone is provided with screw hole 8, screw penetrates wherein, locking, make the magnetic cylinder, retaining washer, moving-coil, poly-sound chamber is mounted to one, integral installation is in plastic casing 9, (as Figure 11, shown in 16), plastic casing 9 and half garden shape top cover 10 are formed resonant cavity, poly-sound chamber 7 places in the middle of the half garden shape top cover 10, one circle tongue 11 is arranged in the plastic casing, the top cover of resonant cavity is fixed on the tongue 11 by connecting the sticking frame of plastic sheet 12 usefulness glue encapsulation, leave the space between plastic casing and the half garden shape top cover and become sound hole, (as Figure 17, shown in 16), allow the chimes of doom unofficial biography of resonant cavity; Be welded with the lead of going out on the moving-coil enamelled wire, the correspondence position of bottom 14 and plastic casing is provided with bolt hole 13, and bolt is gone into bolt hole, promptly becomes burglar alarm voice loudspeaker of the present utility model, (shown in Figure 16,17).
