Embodiment
below in conjunction with embodiment shown in the drawings, the utility model is further described:
embodiment mono-: shown in accompanying drawing 3-4, a kind of coaxial loudspeaker, includes interior monomer 10 and be coaxially located in housing 60 with outer monomer 20, wherein in monomer 10 in order to export bass scope, 20 of outer monomers are in order to export high audio scope.
above-mentioned first, second and third magnet unit 30, 40, 50 form the magnetic structure of the present embodiment, by magnetic conduction heel piece 31 collocation three magnet 32, 42, 52 and three magnetic conductive boards 33, 43, 53 storehouse formation respectively, wherein the magnetic north pole of the magnet 43 of the second magnet unit 40 is towards below to magnetic conduction heel piece 31, and first and second magnet unit 30, 50 magnet 32, 42 magnetic north pole are towards upper and in the face of magnetic conductive board 33, 53, the second magnet unit 40 is had in contrast to the pole arrangement of the first magnet unit 30 and (also can be described as the magnetic moment direction of magnet, be the direction of the south magnetic pole sensing magnetic north pole of magnet).
in these supplementary notes, magnetic conduction heel piece 31 is that high magnetic conductive material is made with magnetic conductive board 33,43,53, at the present embodiment, be to take cold rolling iron and steel as material, magnet 32,42,52 can be selected ferrite lattice or rare earth element magnet, and with rare earth element magnet for better.
as shown in Figure 5, the second magnet unit 40 can be shared by the first magnetic loop 12 and the second magnetic loop 22, in the middle of magnetic gap 125,225, produce uniform magnetic field with the first magnet unit 30 and the 3rd magnet unit 50 simultaneously, can avoid the phenomenon of magnetic leakage to occur, and then improve the drive efficiency with outer voice coil loudspeaker voice coil 23 for interior voice coil loudspeaker voice coil 13.In addition, because the present embodiment is shared the second magnet unit 40, can reach the effect of saving material and reduced volume.
embodiment bis-: shown in accompanying drawing 6, a kind of coaxial loudspeaker, its structure and embodiment mono-are roughly the same, main difference is: interior vibrating diaphragm 11 and outer vibrating diaphragm 21 that outer monomer 10,20 is used are end face and the bottom surfaces that are arranged at respectively aforementioned loud speaker, wherein, the 3rd magnet unit 50 only has magnet 52 and is arranged on housing 60 with magnetic conductive board 53, and 30,40 of first and second magnet units are located at magnetic conduction heel piece 31 by its magnet 32,42 equally.Thus, the magnetic structure of this creation can be brought into play its effect equally, and inside and outside monomer 10,20 can provide different voice output directions.
it is worth mentioning that, the quantity that this creation does not limit monomer is two, and three monomers or more also can be set, and this creation does not limit these magnet units yet must be co-located on same magnetic conduction heel piece.In addition, the quantity of the second magnet unit and the 3rd magnet unit also can change into a plurality of, and annular arrangement is in the periphery of the first magnetic shape unit, for example the second magnet unit may be embodied as four and rectangular magnetic conduction heel piece, magnet and magnetic conductive board, consisted of respectively, and be looped around four limits of the first magnet unit, the 3rd magnet unit is similarly four and rectangular magnetic conduction heel piece, magnet and magnetic conductive board, consisted of respectively, with correspondence, be arranged at the periphery of the second magnet unit, so configuration can also form the voice coil loudspeaker voice coil that two magnetic gaps hold inside and outside vibrating diaphragm.Those skilled in the art can also change depending on actual needs the pole arrangement of each magnet unit, as long as the pole arrangement that maintains the second magnet unit in contrast to first, the pole arrangement of the 3rd magnet unit, just can reach the object of this creation, should be considered as the simple of this creation and change, the claim that should be this case contains.
