Embodiment
As Fig. 1 to shown in Figure 7, according to loud speaker of the present invention, with the integrally formed framework 1 of yoke 2 above, be combined with the ellipse cover 6 that is formed with sound outlet 8 to horizontal direction.Portion is equipped with the necessary yoke 2 of loud speaker, magnet 3, metallic plate 4, vibrating membrane 5 and voice coil loudspeaker voice coil 16 etc. in the nature of things within it.
Specifically, the framework 1 integrally formed with the yoke 2 of container shapes, the cross section of its exterior contour is oval.In addition, on the framework 1 between the exterior contour of framework 1 and the yoke 2, be formed with a plurality of pores 17, so that air is flowed swimmingly during vibrating membrane 5 vibrations with form up and down.Like this pore 17 that forms in order to prevent the inflow as foreign substances such as dusts to greatest extent, in the bottom of this framework 1, is formed with filter 11 with nonwoven fabrics etc.
The bottom of said frame 1 as Fig. 6 a, shown in the 6b, with filter 11, is attached with PCB 13.And on the one side of this PCB 13, be formed with pattern 19 in order to the driving power that connects voice coil loudspeaker voice coil 16 and flow into from the outside.In addition; the outside of said frame 1 one sides; be formed with the guide groove 14 of above-below direction; this guide groove is guided to the outside as the end voice coil loudspeaker voice coil 16, during with PCB 13 welding in order to protect the space of this voice coil loudspeaker voice coil 16, after voice coil loudspeaker voice coil 16 is drawn; generally speaking; with fillings such as silicone resins, when preventing that voice coil loudspeaker voice coil 16 from exposing, protect this voice coil loudspeaker voice coil 16 better.
Exterior contour on said frame 1 top, with certain height be formed with in order in conjunction with two stages of above-mentioned vibrating membrane 5 and above-mentioned cover 6 in conjunction with buckle 10.At this moment, this height in conjunction with buckle 10 is limited to the minimum space of guaranteeing vibrating membrane 5 vibrations at least, and this is in order to reduce the thickness of loud speaker to greatest extent.
In addition, as Fig. 4 a, shown in the 4b,, be formed with in order to prevent that yoke 2 from burying under the state of framework 1 the fixedly buckle 15 that breaks away from because of vibration or other external causes with the outer rim of the integrally formed yoke 2 of said frame 1.In the bottom surface 12 of yoke 2, when utilizing the bonding magnet 3 of common adhesive, the cohesion for 3 of the bottom surface 12 of improving yoke 2 and magnet is formed with a as Fig. 4, concavo-convex 18 shown in the 4b.
At the bottom surface of above-mentioned yoke 2 12 central parts, be attached with the cylindrical shape magnet 3 that is formed with certain space with the inboard of yoke 2, and this magnet 3 above be attached with double layer of metal plate 4.At this moment, as Fig. 5 a, shown in the 5b,, be formed with embossing 20 on the surface of this metallic plate 4 in order to improve the cohesion with metallic plate 4.In order more successfully to guide the magnetic line of force, the diameter that makes metallic plate 4 is natural greater than the diameter of magnet 3.
Interlock is in voice coil loudspeaker voice coil 16, and passes through the vibrating membrane 5 that up-down vibration is pronounced, and has double vaulted shape, its outer rim be fixed in said frame 1 in conjunction with on the buckle 10.Be attached to the voice coil loudspeaker voice coil 16 on above-mentioned vibrating membrane 5 bottom surfaces,, and extend in the space between above-mentioned yoke 2 and the magnet 3 with cylindric winding.
Said frame 1 in conjunction with buckle 10 on, be combined with in order to protection and be installed on magnet 3, metallic plate 4, vibrating membrane 5 and voice coil loudspeaker voice coil 16 etc. on this framework 1, and the sound that sends by the vibration of vibrating membrane 5 of the guiding cover 6 of discharging along horizontal direction.
As Fig. 2 a, 2b, shown in the 2c, the end 7 of an above-mentioned side has the cover 6 of the sound outlet of opening to horizontal direction 8, and when its direction that is formed with sound outlet 8 was seen, the downside of sound outlet 8 ends was more outside more outstanding than upside, and the end on left side or right side is more outstanding than other sides, and top is the center to cover 6 length direction, to the left or the right side tilt.Certainly, identical with said frame 1, the horizontal cross-section of the upper and lower side of above-mentioned cover 6 also is oval.
Therefore, have the loud speaker of sound outlet can be multiple shape embody, the outward appearance that various electronic product internal structures such as the mobile phone of loud speaker or PDA is installed and comprises the electronic product of loud speaker can multiple shape embody.Particularly, owing to can dispose the sound outlet direction of loud speaker in a variety of forms, therefore not only can effectively utilize the inner space of various electronic products, but also can embody the various shapes that comprise the electronic product of loud speaker in a variety of forms.
In sum, according to the present invention, in making the process of mobile phone, PDA and various electronic products, not only have and to change the position of sound outlet or the effect of shape in a variety of forms, but also have the effect that can change the installation constitution of loud speaker in a variety of forms.
In addition, the present invention has reduced the manufacturing engineering of loud speaker to greatest extent by integrally formed yoke and framework.So not only reduced production cost, and prevented because of external impact or make the effect of magnet or metallic plate disengaging because of vibration by strengthening the cohesion between yoke and magnet, magnet and metallic plate, having.
In addition, it is the oval-shaped while that the present invention makes the horizontal cross-section of loud speaker, the end of cover and sound outlet is formed with different height or length, thereby not only make the outward appearance of loud speaker beautiful more, but also have the effect that can be installed on mobile phone, PDA and various electronic products inside with variform.
Moreover,, not only have to make and vibrate vibration of membrane effect more smoothly, can prevent that various foreign matters moneys from flowing into the effect of inside loudspeakers by the filter that is attached on the pore but also have owing to be formed with most pores on the framework.
More than only the preferred embodiments of the present invention have been done detailed description, in technological thought scope of the present invention, it is natural that multiple variation and correction can be arranged, this variation and revise and ought to belong to claim scope of the present invention.
