[embodiment]
The utility model is described in further detail as example below in conjunction with drawings and embodiments, to take acoustical generator.
As Figure 1-3, acoustical generator 1 comprises basin frame 10, is contained in magnetic circuit system 11, the vibrational system (not shown) in described basin frame 10 and is fixed on the conducting terminal 12 on described basin frame 10.
Described magnetic circuit system 11 comprise be fixed on described basin frame 10 bottoms yoke 110, be arranged on main magnet steel 111 in described yoke 110, lay respectively at described main magnet steel 111 both sides and form two secondary magnet steel 112 of magnetic gap (not label) and be arranged at respectively the pole piece 113 on described main magnet steel 111 and secondary magnet steel 112 with described main magnet steel 111.
Described basin frame 10 is rectangle, it comprises sidewall 1000, the receiving space 100 being surrounded by described sidewall 1000 and the convex extension part 103 of extending to described receiving space 100 from described sidewall 1000, and described sidewall 1000 surrounds the groove 104 of accommodating described secondary magnet steel 112 with described convex extension part 103.In the present embodiment, described sidewall 1000 comprises a pair of the first side wall 101, a pair of the second sidewall 102, and described conducting terminal 12 is fixed on described the second sidewall 102, and described convex extension part 103 surrounds two relative grooves 104 with the first side wall 101.
As shown in Figure 3 and Figure 4, described convex extension part 103 has the first lower surface 1031, the side 1032 supporting with described secondary magnet steel 112 and is connected described side 1032 and the first inclined-plane 1033 of the first lower surface 1031.Described convex extension part 103 comprises and connects the connecting portion 1034 of described the first side wall 101 and the extension 1035 extending to 100 bendings of described receiving space from described connecting portion 1034, and described the first inclined-plane 1033 is positioned at described extension 1035.
The described the first side wall 101 of basin frame 10 has the second lower surface 1011, towards the inwall 1012 of described receiving space 100 and connect described inwall 1012 and the second inclined-plane 1013 of the second lower surface 1011.Described the second inclined-plane 1013 has the spaced breach 1010 that connects described inwall 1012 and the second lower surface 1011.
While assembling, secondary magnet steel 112 is installed in basin frame 10 from bottom to top, due to by the part beveling that may touch with secondary magnet steel 112 on basin frame 10, when there is very little off normal in magnetic circuit system 11 and basin frame 10 in assembling process, once secondary magnet steel 112 pressurizeds, understand along the first inclined-plane 1033 and the second inclined-plane 1013 slides into precalculated position and can not damage basin frame 10 by pressure.
