Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is according to the schematic diagram of an embodiment of the high pitch loudspeaker of employing ferrite magnetic circuit of the present utility model.
Embodiment
With reference to the accompanying drawings the utility model is described more fully, exemplary embodiment of the present utility model is wherein described.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 the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.Below in conjunction with figure and embodiment, the technical solution of the utility model is carried out to many-sided description.
As shown in Figure 1, adopt the high pitch loudspeaker of ferrite magnetic circuit to comprise: magnetic circuit device, voice coil loudspeaker voice coil 6, high-frequency diaphragm 7, centring ring 4, socket 2, waveguide type balancer 8 and weld tabs.
Magnetic circuit device comprises: T iron 1, ferrite magnetic steel 2 and train wheel bridge 5; Ferrite magnetic steel 2 is arranged between train wheel bridge 5 and T iron 1, and T iron 1, ferrite magnetic steel 2 and train wheel bridge 5 are combined into magnetic circuit device by gluing connecing.
Centring ring 4 is connected with socket 2 buckles, and magnetic circuit device is encapsulated in socket 2; Voice coil loudspeaker voice coil 6 is arranged between high-frequency diaphragm 7 and centring ring 4, and high-frequency diaphragm 7, voice coil loudspeaker voice coil 6 adopt respectively glue to be adhesively fixed on the top of centring ring 4.
According to an embodiment of the present utility model, electric capacity 10 adopts glue to be adhesively fixed on socket 2, and with the frequency-division filter wire bonds of voice coil loudspeaker voice coil 6.The frequency-division filter wire bonds of electric capacity 10 and voice coil loudspeaker voice coil 6, plays the effect of frequency-division filter.
Adopt ferrite magnetic circuit to replace the cortina ball top high pitch loud speaker of traditional neodymium iron boron magnetic circuit, but the quality of cortina magnetic property heavier and ferrite magnetic steel own is far short of what is expected compared with Nd-Fe-B magnet steel, and be limited to vehicle-mounted high pitch loudspeaker installation site limited space, it is too large that ferrite magnetic steel can not do, if the common design of simple use can be brought high pitch loudspeaker sensitivity deficiency, the poor defect of directive property, client can not accept.
