Abstract
The utility model relates to an integral sounder which comprises a basin frame, a magnetic steel, a T iron, a splint, a press side, and a sound ring, wherein the magnetic steel, the T iron, the splint, and the basin frame are molded into integration and are positioned in the basin frame. The minor diameter par of the T iron is sheathed in the magnetic steel, the major diameter part of the T iron covers the magnetic steel, and the splint is positioned below the magnetic steel and is positioned between the magnetic steel and the basin frame. The minor diameter part of the basin frame is evenly provided with a plurality of radiating grooves of the magnetic steel at the outer part of the magnetic steel, an opening is arranged at the top part of the basin frame, and thus, one part of the T iron is exposed. A reinforcement device of a soldering lug is convexly extended outwards at the periphery of the minor diameter part of the basin frame. Through the structure, the integral sounder with more reliable and beautiful structure and good heat dissipation performance can be obtained, and parts and components of the utility model are not easy to drop.
Description
The utility model relates to a kind of acoustic generator, particularly a kind of integral type acoustic generator.
Along with the application of acoustic generator in every field, people have proposed various new demands to acoustic generator.These require mainly to concentrate on the following aspects: 1. aspect electroacoustic performance, require common faults such as solution magnet steel, the heat radiation of T iron do not come off freely, easily, and require to improve reliability of products; 2. aspect craft label, require the clear and standard of sign; 3. aspect profile, require product-forming attractive in appearance.
What existing in the market acoustic generator adopted is fabricated construction, and magnet steel and T iron are set at the outside of basin frame, and its aesthetic property is relatively poor, causes part to come off easily, and is difficult for carrying out craft label.
Therefore, to sonorific new demand, it is reliable more and attractive in appearance and be difficult for the integral type acoustic generator that causes parts to come off to aim to provide a kind of structure at people for the utility model.
The purpose of this utility model is achieved like this, and a kind of integral type acoustic generator is provided, and it comprises: basin frame, magnet steel, T iron, clamping plate, flanging and voice coil loudspeaker voice coil, wherein, described magnet steel, T iron, clamping plate and described basin shut die are made one, and are positioned at the inside of basin frame.
Because the utility model adopts method of moulding that magnet steel, T iron, clamping plate and basin frame are made for one and is positioned at the inside of basin frame, therefore makes that whole sonorific structure is more reliable and attractive in appearance, and is difficult for causing coming off of parts.
Below in conjunction with accompanying drawing, a sonorific preferred embodiment specifically describes to integral type of the present utility model.
Fig. 1 is the structure cutaway view of the sonorific preferred embodiment of the utility model integral type;
Fig. 2 is the sonorific plane graph of integral type shown in Figure 1;
Fig. 3 is the assembling schematic diagram of sonorific weld tabs of the utility model integral type and basin frame; And
Fig. 4 is the weld tabs of sonorific another embodiment of the utility model integral type and the assembling schematic diagram of basin frame, and wherein Fig. 4 a is that the K of Fig. 4 is to view.
See also each accompanying drawing, integral type acoustic generator of the present utility model comprises: basin frame 1, magnet steel 6, T iron 3, clamping plate 2, flanging 9 and voice coil loudspeaker voice coil 10.Described magnet steel 6, T iron 3, clamping plate 2 form one by the injection molding operation of plastic tub frame 1 with basin frame 1, and are positioned at the inside of basin frame 1.Basin frame 1 can be divided into a small diameter portion 1a and a major diameter part 1b.
As shown in Figure 1, it is the sonorific cutaway view of the utility model integral type, shows the sonorific structure that is integral through injection molding.Wherein, the small diameter portion of T iron 3 is nested with in magnet steel 6, and the external diameter of the major diameter of T iron 3 part roughly equates with the external diameter of magnet steel 6, covers magnet steel 6 thus.Clamping plate 2 are below the magnet steel 6, between magnet steel 6 and basin frame 1.
The small diameter portion 1a of described basin frame 1 is provided with several magnet steel heat radiation grooves 8 equably in the outside of magnet steel 6, make these parts of magnet steel 6 directly to contact with air thus, thereby help the heat radiation of magnet steel 6.Described basin frame 1 leaves an opening 7 at its top, thereby the part of T iron 3 is exposed.Like this, both helped the heat radiation of T iron 3, and can also provide correct positioning, thereby solved the difficult problem that the sign standardization is printed for identification marking or sign.Described opening can be Any shape, for example elliptical shape as shown in Figure 3.
The outside projection of periphery at the small diameter portion 1a of basin frame 1 has a weld tabs bracing means 5.In Fig. 1 and Fig. 3, described weld tabs bracing means 5 is the projections that extend radially outwardly along basin frame 1.On the bottom surface of described projection, be provided with a press strip 51, in order to compressing the arc weld tabs 4 after the insertion, and with gluing and weld tabs 4 is reinforced.In Fig. 4 and Fig. 4 a, described weld tabs center bracing means 5 is one along the oblique then projection that has a down dip of extending radially outwardly of basin frame 1.
Described weld tabs bracing means 5 has improved the bond strength of weld tabs 4 with basin frame 1 greatly, and matches with integral structure, and making product is to throw, lose, throw not make its damage of falling apart.
Described flanging 9 usefulness adhering methods are pressed on the limit, outer of sound film 11, even be subjected to greater impact, sound film 11 are come off.
