Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present utility model, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making all other embodiment that obtain under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of electromagnetic sounder, refers to the side sectional view of electromagnetic sounder shown in Fig. 3.Described electromagnetic sounder 3 comprises ball top 30, ring 31, pole piece 33, magnet steel 34, voice coil loudspeaker voice coil 35, magnetic bowl 36 and basin frame 37.
Described basin frame 37 is support bodys of adopting tool receiving space made of plastic (not indicating), described receiving space both ends open.Described basin frame 37 forms the first ladder 370 and the second ladder 371 in described receiving space.Described the second ladder 371 is divided into described receiving space two parts of up/down perforation.In other embodiments, electromagnetic sounder can not comprise basin frame, and vibrational system is directly fixed on magnetic circuit system.
The circulus that described ring 31 is hollow, it comprises inner edge 310 and the hollow region being surrounded by described inner edge 310.The outer ledge of described inner edge is corresponding to the interior profile of the first ladder 370 of described basin frame 37, and the inner edge of described ring is by the surface binded of the first ladder 370 of adhesive and described basin frame 37.
Described ball top 30 is positioned at the hollow region of described ring 31, and both cooperations surround a lid, and described lid is the vibrating diaphragm of described electromagnetic sounder 3, forms the vibrational system that forms described electromagnetic sounder 3.If desired, simultaneously by vibrating diaphragm described in the spring leaf (not shown) fixed support bonding together with it, to improve oscillation intensity.
Described ball top 30 comprises body 301 and boss 302, and described boss 302 is located at described body 301 edges, and around described body 301.Described boss 302 is a right angle step, and it comprises first end 303, is positioned at the second end 304 and the middle coupling part 305 of described first end 303 belows.Described coupling part 305 arranges perpendicular to described first end 303, the second end 304 simultaneously.The inner edge 310 of described ring 31 and the first end 303 surface binded settings of described boss 302.Described coupling part 304 is towards extending perpendicular to described ring 31 directions.Described first end 303 is contrary with respect to the bearing of trend of described coupling part 305 with the second end 304.The center line on described ball top 30 of take is the center of circle, the outline diameter of described the second end 304 is greater than the outline diameter of described first end 303, and described the second end 304 extends towards being parallel to described ring 31 directions, and extends to the below of the inner edge 310 of described ring 31.That is to say, the distance between described the second end 304 and described ball Ding30 center is greater than the distance between described first end 303 and Qiu Ding 40 centers.
Meanwhile, because the height value of described coupling part 304 is greater than the thickness of described ring 31, so there is a spacing between described the second end 304 and described ring 31.
Described pole piece 33, described magnet steel 34, described voice coil loudspeaker voice coil 35 and described magnetic bowl 36 form the magnetic circuit system of described electromagnetic sounder 3.
Described magnetic bowl 36 is housed in the lower part of the receiving space of described basin frame 37, and it comprises diapire 360 and sidewall 362.Described diapire 360 is slab construction, and described sidewall 362 vertically extends to form from each edge homonymy of described diapire 260, and coordinates described diapire 360 to surround the receiving space of another end opening.
Described magnet steel 34 and the superimposed setting of described pole piece 33, described pole piece 33 is arranged on the surface of described magnet steel 34, and correspondence is contained in the receiving space of described magnetic bowl 36 jointly, and described magnet steel 34 is sandwiched between the diapire 360 and described pole piece 33 of described magnetic bowl 26.Meanwhile, between the outer surface of described magnet steel 34 and described pole piece 33 and the inner surface of described magnetic bowl 36, be provided with gap, i.e. magnetic gap.
Described voice coil loudspeaker voice coil 35 is circulus, and it arranges around described magnet steel 34, and and described magnet steel 34 between keep spacing, one end of described voice coil loudspeaker voice coil 35 is installed in second end 304 on described ball top 30, the other end is outstanding setting.Because there is a spacing between the first end 303 on described ball top 30 and described the second end 304, so there is equally spacing between described voice coil loudspeaker voice coil 35 and the inner edge 310 of described ring 31, the size of described distance values depends on the length of the coupling part 305 that connects described first end 303, the second end 304.
After described electromagnetic sounder 3 assemblings, the inner edge 310 of described ring 31 is bonding with the outer ledge on described ball top 30, and the surface binded of the first ladder 370 of its outer ledge and described basin frame 37.Described magnet steel 34 and described pole piece 33 be superimposed to be housed in the receiving space of described magnetic bowl 36, between described magnet steel 34 and the outer surface of described pole piece 33 and the inner surface of described magnetic bowl 36, be provided with gap, described gap is the magnetic gap 363 of described electromagnetic sounder 3 simultaneously.Described voice coil loudspeaker voice coil 35 is connected with second end 304 on described ball top 30, to provide actuating force to described ball top 30.The other end of described voice coil loudspeaker voice coil 35 is suspended in described magnetic gap 363.
In described electromagnetic sounder 3 of the present utility model, the edge on described ball top 30 forms first end 303, coupling part 305 and the second end 304, and the spacing between described first end 303, the second end 304 is pulled open in described coupling part 305.The end that suspends of described voice coil loudspeaker voice coil 35 highly can be determined by the length of described coupling part 305.
In the present embodiment, according to actual design needs, design the length of described coupling part 305, described voice coil loudspeaker voice coil 35 other ends of corresponding effectively adjustment are housed in the length in described magnetic gap 363.This design can significantly increase the oscillation space of described voice coil loudspeaker voice coil 35 in described magnetic circuit system, and the major part of described voice coil loudspeaker voice coil 35 is stablized and remained in magnetic gap, improves electromagnetic field utilance.Meanwhile, avoid supporting voice coil loudspeaker voice coil 35 with independent speech coil framework, further reduce the spacing between described voice coil loudspeaker voice coil 35 and described pole piece 33, increase voice coil loudspeaker voice coil utilance, effectively improve magnetic circuit linearity.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
