Therefore, be necessary to propose a kind of improvement, to overcome existing speaker unit defect.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of production efficiency is high, reliability is high, acoustical behavior is good speaker unit and the manufacture method of shell thereof.
To achieve these goals, the present invention is by the following technical solutions:
A kind of speaker unit, involving vibrations system, magnetic circuit system and auxiliary system, described auxiliary system comprises shell and the electric-conductor of accommodating fixing described vibrational system and described magnetic circuit system, the limit magnet that described magnetic circuit system comprises centring magnet and arranges around described centring magnet, described centring magnet is provided with center washer near described vibrational system one side, described limit magnet is provided with limit washer near described vibrational system one side, and: described limit washer is combined with described shell integrated injection molding, and described electric-conductor is combined with described shell integrated injection molding.
As the preferred technical scheme of one, described vibrational system comprises voice coil loudspeaker voice coil, and described voice coil loudspeaker voice coil is provided with voice coil leads, and described voice coil leads is along described limit washer fair line, and described voice coil leads is electrically connected with described electric-conductor.
As further preferred, described voice coil leads is by fixing glue and described limit washer location.
Meanwhile, the manufacture method of the shell of speaker unit of the present invention: the limit washer with material-strap structure, electric-conductor are fixed with injection forming mold respectively; Carry out injection moulding, form shell by injection molding process, shell and limit washer, electric-conductor are one-body molded; Cooling, after shell, limit washer and electric-conductor integrative-structure are cooling, excise described limit washer material strip and electric-conductor material strip.
Speaker unit of the present invention, limit washer, electric-conductor are all combined with shell integrated injection molding, improve the firm degree that limit washer, electric-conductor are combined with shell, improve the reliability of speaker unit, and limit washer, electric-conductor are combined with shell integrated injection molding, in speaker unit assembling production process, independent fixed edge washer and electric-conductor again, simplifies production process, enhances productivity; Limit washer is combined with shell integrated injection molding, can increase limit washer area, is conducive to speaker unit magnetic circuit and maximizes design, improves speaker unit acoustical behavior.Therefore, speaker unit of the present invention has advantages of that production efficiency is high, reliability is high, acoustical behavior is good.
Brief description of the drawings
Fig. 1 is that speaker unit shell mechanism of the present invention is combined schematic diagram with voice coil loudspeaker voice coil;
Fig. 2 is the schematic diagram of speaker unit shell mechanism shown in Fig. 1;
Fig. 3 is the schematic diagram of speaker unit manufacture process shown in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, describe content of the present invention in detail:
Speaker unit of the present invention, similar with traditional structure speaker unit, involving vibrations system, magnetic circuit system and auxiliary system, auxiliary system comprises accommodates the electric-conductor that fixing vibrational system is electrically connected with external circuit with the shell of magnetic circuit system and by speaker unit, and vibrational system comprises vibrating diaphragm and voice coil loudspeaker voice coil; The limit magnet that magnetic circuit system comprises centring magnet, arranges around centring magnet, centring magnet and limit magnet are respectively arranged with center washer and limit washer near vibrational system one side, between centring magnet, center washer and limit magnet, limit washer, be provided with magnetic gap, vibrational system voice coil loudspeaker voice coil is arranged in magnetic gap, when speaker unit work, foreign current enters voice coil loudspeaker voice coil, and the voice coil loudspeaker voice coil being arranged in magnetic gap is subject to Lorentz force action up-down vibration, drives vibrating diaphragm vibration sounding.
As shown in Figures 1 and 2, speaker unit of the present invention limit washer 2 and electric-conductor 3 are wholely set with shell 1.Limit washer 2, electric-conductor 3 and shell 1 are by integrated through injection molding combination, improve the firm degree of limit washer 2, electric-conductor 3 and shell 1 combination, improve the reliability of speaker unit, and, limit washer 2, electric-conductor 3 are combined with shell 1 integrated injection molding, in speaker unit assembling production process, needn't carry out separately the assembling of limit washer 2, electric-conductor 3 again and fix, simplify the production process of speaker unit, enhance productivity; Limit washer 2 is combined with shell 1 integrated injection molding, can increase the area of limit washer 2, is conducive to speaker unit magnetic circuit and maximizes design, improves speaker unit acoustical behavior.Should know, speaker unit shown in accompanying drawing is only a concrete case study on implementation of speaker unit of the present invention, in the time of practical application, limit washer 2 can as shown be two-part structure setting, also can comprise four part-structures, can also be annular design, all can embody loadspeaker structure advantage of the present invention.
