[detailed description of the invention]
Below in conjunction with drawings and embodiments, this utility model is described in further detail.Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
As illustrated in fig. 1 and 2, this utility model provides a kind of speaker 1, and it includes frame 10, group is assigned in the magnetic circuit system 11 in described frame 10 and vibrational system 12 and joins formation receiving space to house the protecgulum 13 of above-mentioned vibrational system 12 and magnetic circuit system 11 with described frame 10 groups.Described magnetic circuit system 11 is used for producing magnetic field, and described vibrational system 12 is driven to create vibration in described magnetic field, thus sending sound.
Described vibrational system 12 includes vibrating diaphragm 120 and drives the voice coil loudspeaker voice coil 121 of this vibrating diaphragm 120 vibration sounding.Described voice coil loudspeaker voice coil 121 includes speech coil framework 1210 and the coiling group 1211 being fixed on this speech coil framework 1210, and described speech coil framework 1210 is made up of paper, plastics or any one material of metal.This utility model preferred embodiment in, described speech coil framework 1210 is made up of crystallite lattice (microlattice) metal material, this material is a kind of microcrystalline lattice being made up of interconnective hollow pipe, it has very strong resistance to compression and good absorption characteristic, such as, this crystallite lattice metal material can be connected with each other by Hollow Nickel metal tube and form.
Yoke 110 that described magnetic circuit system 11 includes being fixed on described frame 10 and be stacked at this yoke 110 central position successively from top to bottom: first main pole core 111, first main magnet steel the 112, second main pole core the 113, second main magnet steel 114 and until the n-th main pole core and the n-th main magnet steel, described N is the integer be more than or equal to 2, wherein, the adjacent magnetic pole homopolarity between main magnet steel is oppositely arranged.In order to this utility model is explicitly described, so that those skilled in the art are understood that the technical solution of the utility model, in the present embodiment, existing is 2 by n value.
The magnetic pole homopolarity of described first main magnet steel 112 and the second main magnet steel 114 is oppositely arranged, again owing to being provided with the second main pole core 113 between described first main magnet steel 112 and the second main magnet steel 114, therefore, the magnetic line of force that described first main magnet steel 112 and the second main magnet steel 114 produce will be assembled and be sent in the magnetic gap of its week side in the second main pole core 113, so that the voice coil loudspeaker voice coil 121 in magnetic gap is subject to bigger magnetic field force, it is effectively improved the driving force of voice coil loudspeaker voice coil 121, thus improve the sensitivity of speaker 1.So that the magnetic field that described voice coil loudspeaker voice coil 121 is subject to is the strongest, preferably, when described voice coil loudspeaker voice coil is in equilbrium position, described coiling group 1211 is between upper surface place plane and the lower surface place plane of the main magnet steel of N of described first main magnet steel 112, due in the present embodiment, described N value is 2, and therefore, described coiling group 1211 is between the upper surface place plane and the lower surface place plane of the second main magnet steel 114 of described first main magnet steel 112.
