Abstract
The utility model discloses a loudspeaker-distortion-reducing magnetic circuit system comprising a bow-shaped magnetizer, the center of the inner part of the magnetizer is provided with a magnetic steel, the upper end of the magnetic steel is provided with a washer, the top part of the magnetizer is provided with an annular boss toward the inner side which equals the washer in thickness, and the top part of the annular boss is level with the top part of the washer. The loudspeaker-distortion-reducing magnetic circuit system provided by the utility model can enable a conventional television loudspeaker to be further reduced in distortion, and high fidelity quality of a product can be guaranteed.
Description
Technical field
The utility model relates to a kind of magnetic circuit system that reduces loudspeaker distortions.
Background technology
In recent years, along with the structure of television set is done thinner and thinner, in order to meet its needs, width that loud speaker will do is narrow, thin thickness, in this case, due to the structural limitations of loud speaker, the impact of the ultra-thin and vibrational system of magnetic circuit of loudspeaker, it easily produces distortion and under powered problem, has limited to a great extent the playback to high-quality music.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, and a kind of novel magnetic circuit of loudspeaker is provided, to reduce distortion and the underpower of the magnetic circuit of loudspeaker.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of magnetic circuit system that reduces loudspeaker distortions of the utility model, comprise the magnetic conductor that is bowl-shape setting, described magnetic conductor inside center is provided with a magnet steel, described magnet steel upper end is provided with a washer, described magnetic conductor top is provided with a ring dress boss equal with described washer thickness to the inside, and described ring dress boss is concordant with described washer top.During fabrication, this ring dress boss can one-shot forming, also can form with the metal material riveted of different-thickness.
The beneficial effect that the utility model reaches is:
In the time being combined into a finished product magnetic circuit, its magnetic flux can form a complete magnetic loop system by washer, magnetic conductor, owing to having increased a ring dress boss equal with washer thickness at magnetic conductor top, due to the directed movement characteristic in magnetic field, make to equate greatly in the magnetic flux density of washer both sides, when loudspeaker coil is moved between magnetic field, suffered power is more balanced, has reduced the distortion that product causes due to magnetic field in the time of work.Due to above design improvement, can make the distortion of present TV loudspeaker further be promoted, ensure the quality of product high-fidelity.
Brief description of the drawings
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of magnetic circuit system that reduces loudspeaker distortions of the utility model, comprise the magnetic conductor 1 that is bowl-shape setting, the inside center of described magnetic conductor 1 is provided with a magnet steel 2, described magnet steel 2 upper ends are provided with a washer 3, described magnetic conductor 1 top is provided with a ring dress boss 4 equal with described washer 3 thickness to the inside, and described ring dress boss 4 is concordant with described washer 3 tops.
In the time being combined into a finished product magnetic circuit, its magnetic flux can form a complete magnetic loop system by washer 3, magnetic conductor 1, owing to having increased a ring dress boss 4 equal with washer 3 thickness at magnetic conductor 1 top, due to the directed movement characteristic in magnetic field, make to equate greatly in the magnetic flux density of washer 3 both sides, when loudspeaker coil is moved between magnetic field, suffered power is more balanced, has reduced the distortion that product causes due to magnetic field in the time of work.
Due to above design improvement, can make the distortion of present TV loudspeaker further be promoted, ensure the quality of product high-fidelity.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
