Abstract
The utility model relates to a super thin type loud-speaker, which is composed of a case, a vibrating membrane, a ring stand, a voice coil, a magnet, a pad, etc. The utility model is characterized in that the vibrating membrane is formed by binding and combining outer annular pieces with two different materials and plastic films which are cut into larger than the annular holes of the annular pieces. The material of the film is the same with that of the common plastic vibrating membrane, however, the annular piece is manufactured by binding a rubber hem, a sponge hem or cloth hem, etc. Due to the fact that the utility model has higher stretching function when the outer annular piece of the vibrating membrane has big power, the utility model can bear large power; moreover, the effective frequency bandwidth is flatter, and has no vibratory murmur.
Description
The utility model relates to a kind of super-thin speaker.
Common being seen super-thin speaker, as earphone notebook computer or small-sized walkman and include the super-thin speaker of cassette player etc. being usually used in, all be made up of a cap, a vibrating membrane (MYLAR CONE), a ring stand, a voice coil loudspeaker voice coil, a magnet and a member such as packing ring, vibrating membrane wherein is to make with the one-body molded mode of plastic film.The structure of this super-thin speaker and material therefor comprise that the material of each parts wherein all never changes to some extent, and since being extensive use of, that finds this kind super-thin speaker bears power quite little (about 0.1W), and vibrating membrane vibrates noise and its F often
0Be worth very highly, also lack low-frequency effect, effective frequency range narrower (between 300HZ-2000HZ) is so the actual acoustics of using is unsatisfactory.Yet because the restriction of its structure, only pipe is known already and is had above-mentioned many defectives, but still never has the people this to be proposed effective corrective measure up to now.
The purpose of this utility model provides a kind of super-thin speaker that can overcome above-mentioned multinomial defective.
The utility model is achieved in that and includes cap, vibrating membrane, ring stand, voice coil loudspeaker voice coil, magnet and packing ring, above-mentioned cap is installed with a preceding pole piece at chosen place, be located in the mesopore of cap with ring stand with shape for hat pedestal shape, and be fastened in the mesopore outer wall and magnet and pad have been inserted in combination in ring stand with its marginal ridge portion; Above-mentioned voice coil loudspeaker voice coil should be adhered to the below of vibrating membrane in advance, place cap with vibrating membrane, the lucky winding of voice coil loudspeaker voice coil is set in around magnet and the pad, and the preceding pole piece two ends that two strands of leads that make voice coil loudspeaker voice coil are overlapped on cap respectively are weldingly connected, it is characterized in that: above-mentioned vibrating membrane is by the outer ring sheet of two kinds of unlike materials and cuts into bonding the constituting of plastic film that is slightly larger than outer ring sheet annular distance, the material of this plastic film is identical with the material of common plastics vibrating membrane, and the outer ring sheet is then made with Cushions, sponge limit or selvedge material adhesive.
Characteristics of the present utility model are that its vibrating membrane (MYLAR CONE) is to utilize the outer ring sheet of two kinds of unlike materials and cut into bonding the constituting of plastic film that is slightly larger than outer ring sheet annular distance, especially the outer ring sheet is made for adopting materials such as Cushions, sponge limit or selvedge, have better extension, can bear bigger power.Through the reality test, this power bears approximately and reaches about 1W, and has big smooth effective frequency range (between 200HZ-4000HZ), the friction noise, and cost is low.
Fig. 1 is a combination stereogram of the present utility model;
Fig. 2 is a combination section of the present utility model;
Fig. 3 is an exploded perspective view of the present utility model;
Fig. 4 is the decomposing schematic representation of vibrating membrane in the utility model;
Referring to each accompanying drawing, the utility model includes cap 1, vibrating membrane 2 (MYLAR CONE), ring stand 3, voice coil loudspeaker voice coil 4, magnet 5 and pad 6, cap 1 is installed with a preceding pole piece 7 at chosen place, because of the utility model improves at the structure of vibrating membrane 2 specially, and other components and parts are all original traditional structure, so repeat no more.The utility model mainly is by the outer ring sheet 21 of two kinds of unlike materials with cut into plastic film 22 bonding the constituting (as shown in Figure 4) that are slightly larger than outer ring sheet annular distance with above-mentioned vibrating membrane 2, wherein, the material of this plastic film 22 is identical with the material of common plastics vibrating membrane, and outer ring sheet 21 is then made with rubber sheet limit, sponge limit or selvedge material adhesive.This vibrating membrane 2 cooperates other relevant components and parts just can form a complete super-thin speaker again.
During assembling, pole piece 7 before on cap 1 breach 11 corresponding surfaces, setting firmly in advance, the ring stand (YOKI) 3 that will be shape for hat pedestal shape again is located in the mesopore 12 of cap 1, and is held in mesopore 12 outer walls and combination does not destroy again and inserts magnet 5 and pad 6 in the frame 3 with marginal ridge portion 31.Above-mentioned voice coil loudspeaker voice coil 4 can stick in vibrating membrane 2 belows in advance, insert cap 1 with vibrating membrane 2, and make voice coil loudspeaker voice coil 4 lucky windings around magnet 5 and pad 6, make two leads 41,42 of voice coil loudspeaker voice coil 4 be overlapped on the two ends utmost point of the preceding pole piece 7 of cap 1 respectively, for solder bond.Because the outer ring sheet 21 of vibrating membrane 2 of the present utility model has extension preferably, more powerful (can reach about 1W) that it bears so the utlity model has big smooth effective frequency range, not only do not have vibratory murmur, its low frequency F
0Be worth also lowly, effectively frequency range scope big (between 200HZ-4000HZ) can also be controlled the height change of F value, has obviously improved the quality of super-thin speaker.
