Following embodiment will further specify the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Figure 1 shows that a preferred embodiment of loudspeaker combination of the present invention.This loudspeaker combination 10 comprises that a bass horn 20, a loudspeaker 30 reach for a support 40 that this loudspeaker 30 is mounted on this bass horn 20.
This bass horn 20 comprises that a basin frame 21, a base 23, a magnet 25, a washer 27, a voice coil loudspeaker voice coil 29, a vibrating diaphragm 22 and play ripple 24.
This base 23 is made by magnetic conductive material.This base 23 comprises that the base plate 230 of a circle reaches by the upwardly extending column 232 of the central vertical of this base plate 230.This magnet 25 all is circular with washer 27, and described magnet 25 and washer 27 are stacked and placed on the base plate 230 of this base 23 successively and are located on the periphery of column 232.Form a magnetic gap 250 between the column 232 of this base 23 and this washer 27 and the magnet 25.Thereby magnet 25 is compared to projecting inward more close voice coil loudspeaker voice coil 29 in the inner of this washer 27, so that magnetic gap 250 obtains higher magnetic density.In the present embodiment, this base 23, magnet 25, the washer 27 common magnetic circuit systems of forming.In other embodiment, this magnetic circuit system also can be other traditional modes, as comprises that U iron, magnet, washer, this magnet, washer be located in the U iron, and the magnetic gap that is used for accommodating voice coil loudspeaker voice coil 29 lower ends then is formed between the inwall of magnet, washer and U iron.
This basin frame 21 roughly is bowl-shape, and it has less bottom and a bigger top.This basin frame 21 is located on this washer 27 and with washer 27 and is fixed.The outside of this basin frame 21 is provided with a binding post 210.Certainly, under the less demanding situation for tonequality, also can omit washer 27, thereby the bottom of basin frame 21 is directly fixed on the magnet 25.
This voice coil loudspeaker voice coil 29 comprises the skeleton 290 of a tubular and is wrapped in a coil 292 of the lower end setting of also close skeleton 290 on these skeleton 290 outer peripheral faces.This voice coil loudspeaker voice coil 29 is located on the periphery of the column 232 of base 23, and its lower end stretches in the magnetic gap 250.This vibrating diaphragm 22 is one-body molded by polyethylene terephthalate (PET), PEN (PEN), Polyetherimide (PEI) or polyimides light materials such as (PI).Vibrating diaphragm 22 comprises central part 220 and the outstanding limit 222 around central part 220 of presenting convex.It is tapered to hang limit 222, increases gradually up down without leave in it, thereby forms less bottom and a bigger top.Vibrating diaphragm 22 is located in the basin frame 21, and outstanding 222 less bottoms, limit are sheathed on the peripheral of voice coil loudspeaker voice coil 29 and fix with skeleton 290 upper ends of voice coil loudspeaker voice coil 29, and bigger top, outstanding limit 222 then is adhesively fixed with the top of basin frame 21.This plays ripple 24 ringwise, and it is sheathed on the peripheral of voice coil loudspeaker voice coil 29 and between vibrating diaphragm 22 and washer 27.The inner peripheral of this bullet ripple 24 and voice coil loudspeaker voice coil 29 fix, and the outer peripheral edges of this bullet ripple 24 and basin frame 21 fix, and shake when preventing that voice coil loudspeaker voice coil 29 from vibrating vertically, thereby produce noise when avoiding these bass horn 20 work, reduce the distortion of sound.
See also Fig. 2, this support 40 is fixed in the top of basin frame 21, and it comprises the pressure ring 42 of a ring-type, the snap ring 44 of a ring-type and the rib 46 of some connection pressure rings 42 and snap ring 44.This pressure ring 42 is positioned at support 40 outsides, and this snap ring 44 is positioned at support 40 inboards.This pressure ring 42 is adhered to the top on outstanding limit 222 and the top that will hang limit 222 is pressed and is located at basin frame 21 tops.The diameter of this snap ring 44 is much smaller than the diameter of pressure ring 42, and it is positioned at the below of pressure ring 42 near the position of the central part 220 of vibrating diaphragm 22.The outside wall surface of these rib 46 Joining clasps 44 and the internal face of pressure ring 42.Each rib 46 all curved and these ribs 46 arranges around snap ring 44.The width of each rib 46 is controlled in suitable scope, because too wide meeting stops the pronunciation of bass horn 20, and the too narrow support force that abundance then can't be provided for loudspeaker 30.Formation opening 48 spreads out of for the sound of bass horn 20 between the adjacent rib 46.This support 40 adopts to be made such as the rigid material of metal, possessing enough intensity, and prevents from resonating with loudspeaker 30.
This loudspeaker 30 is arranged in the snap ring 44 of support 40 and is suspended at vibrating diaphragm 22 tops.This loudspeaker 30 comprises a body 32 and is fixed in the installation portion 34 of body 32 belows.This body 32 structure and the structural similarity of bass horn 20, also comprise magnet, washer, base, vibrating diaphragm and basin frame elements such as (all not shown), only dimensionally to some extent the reduction.This body 32 is walked around from basin frame 21 tops and is fixed on the binding post 210 by being attached to lead (not shown) on the rib 46.This installation portion 34 is by making such as the isoelastic material of plastic cement.The outer surface of this installation portion 34 is the arc surfaced of evagination, and its maximum gauge is greater than the aperture of snap ring 44.Thus, deformation takes place in installation portion 34 after penetrating snap ring 44, and then is fastened on the internal face of snap ring 44 by the frictional interference cooperation.And, because the outer surface of installation portion 34 is the arc surfaced of evagination, therefore can be snap ring 44 in bigger angular range be rotated (such as about or the front and back rotation), thereby change loudspeaker 30 towards, to produce high pitch pointedly.One stop part 36 is further formed on the bottom of this installation portion 34.This stop part 36 is in the form of annular discs, and its diameter is greater than the internal diameter of snap ring 44.The bottom partition distance of the top of this stop part 36 and snap ring 44 is with the rotation of spacing this installation portion 34.The length of this distance has determined the rotation amplitude of installation portion 34, and distance is more long, and the rotation amplitude of installation portion 34 is more big.But, must guarantee that the bottom surface of stop part 36 and the central part 220 of vibrating diaphragm 22 separate sufficient distance, to avoid stopping the vibration of central part 220.
The combination 10 of above-mentioned loudspeaker is by arranging loudspeaker 30 at bass horn 20, makes this loudspeaker combination 10 be installed on the casing of an audio amplifier or on other device (not shown) the time, and is easy for installation and can save loudspeaker and make up 10 shared spaces.And because loudspeaker 30 is to be suspended at vibrating diaphragm 22 tops by support 40, therefore need not wear out vibrating diaphragm 22 by other supporting tool supports loudspeaker 30, thereby keeps the integrality of vibrating diaphragm 22, guarantees the bass effect of bass horn 20.
