Description
Technical field
The utility model belongs to speaker technology field, and in particular to a kind of multipath magnetic circuit loudspeaker.
Background technique
Loudspeaker is the electro-acoustic element for converting electrical signals to sound, and loudspeaker currently on the market is mainly that single magnetic circuit is raised
Sound device, in the loudspeaker of this list magnetic structure, the internal magnetic field lines of centring magnet cannot be fully utilized, using incomplete,
And in order to make the magnetic field of magnetic gap reach loudspeaker needs magnetic field strength, must just increase the volume of centring magnet so that
Centring magnet volume is excessive, is unfavorable for the miniaturization of loudspeaker, and if in order to meet the small form factor requirements of loudspeaker, reduction center
The volume of magnet, and the magnetic field strength in magnetic gap can be reduced, cause audio signal sensitivity when being converted into sound lower.
Utility model content
In order to make up for the defects of the prior art, the utility model provides a kind of simple multipath magnetic circuit loudspeakers of structure.
The utility model is achieved by the following technical solution:
A kind of multipath magnetic circuit loudspeaker, including front cover, bracket and sound film, outer pole piece are equipped with center magnet steel, center magnetic strength four
It is laid with outer steel week, the center magnet steel is equipped with center pole piece, and the outer pole piece is equipped with side and the bracket of center magnet steel
Fasten, polar ring be equipped in the bracket, polar ring is equipped with sound film, be located on bracket sound film side be screwed before
Lid.
Further, the outer pole piece periphery is equipped with step.
Further, the side both ends on the bracket positioned at outer pole piece are symmetrically arranged with spring leaf, correspond to spring leaf on bracket
Equipped with card slot.
Further, spring leaf is corresponded in the bracket equipped with welded disc.
The beneficial effects of the utility model are: structure is simple, product outline size can not increased, do not losing product
Under the premise of energy, the magnetic field of magnetic gap is made to reach the magnetic field strength of loudspeaker needs.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the structural schematic diagram of the utility model；
Attached drawing 2 is the structural schematic diagram of the utility model bracket.
In figure, 1 outer pole piece, 2 outer steels, 3 center magnet steel, 4 center pole pieces, 5 brackets, 6 polar rings, 7 sound films, 8 front covers, 9 bullets
Reed, 10 card slots, 11 welded discs.
Specific embodiment
A kind of multipath magnetic circuit loudspeaker of the utility model is further described below with reference to embodiment.
Attached drawing 1,2 is a kind of specific embodiment of the utility model.A kind of multipath magnetic circuit loudspeaker of the utility model, including it is preceding
Lid 8, bracket 5 and sound film 7, outer pole piece 1 are equipped with center magnet steel 3, and center magnetic strength surrounding is laid with outer steel 2, the center magnetic
Steel 3 is equipped with center pole piece 4, and the outer pole piece 1 is equipped with the side of center magnet steel 3 and bracket 5 fastens, and is equipped in the bracket 5
Polar ring 6, polar ring 6 are equipped with sound film 7, and the side that sound film 7 is located on bracket 5 has been screwed front cover 8.
Further, 1 periphery of outer pole piece is equipped with step.
Further, the side both ends on the bracket 5 positioned at outer pole piece 1 are symmetrically arranged with spring leaf 9, correspond to bullet on bracket 5
Reed 9 is equipped with card slot 10.
Further, spring leaf 9 is corresponded in the bracket 5 equipped with welded disc 11.
A kind of multipath magnetic circuit loudspeaker of the utility model guarantees that the internal magnetic field lines of center magnet steel 3 can be fully utilized, applies
Completely, so that the magnetic field of magnetic gap is reached the magnetic field strength of loudspeaker needs, and the volume without increasing centring magnet, make loudspeaker
Miniaturization, it is ensured that lead to audio signal sensitivity when being converted into sound.
Anyone should learn that makes under the enlightenment of the utility model has same or similar skill with the utility model
Art scheme, each falls within the protection scope of the utility model.
Technology that the utility model is not described in detail, shape, construction portion are well-known technique.
