Abstract
The utility model relates to a voice membrane voice coil for a loudspeaker. The utility model is mainly characterized in that plastic or the mixture of plastic and glass fiber is adopted to form a voice membrane, wherein, the bottom surface of which is simultaneously provided with a voice coil ring. The periphery of the voice membrane has proper thickness, which is convenient for being combined with a horn and a yoke plate. The voice coil ring is wound with a coil to form a voice coil. Through the structure, the utility model can effectively solve the problems that a voice membrane and a voice coil of an existing loudspeaker can not be easily combined, and defective fraction is high.
Description
The utility model relates to a kind of sound film voice coil loudspeaker voice coil of loud speaker.
Figure 3 shows that the exploded view of existing loud speaker, it roughly includes loudspeaker 70, a sound film 80, a sound film stator 90 and a yoke 91, wherein loudspeaker 70 bottom periphery are formed with fixing hole 71 respectively in the isogonism place, supply in conjunction with sound film 80, sound film stator 90 and yoke 91.These sound film 80 central authorities are formed with a vibrating membrane 81 that is dome-shaped projection, and sound film 80 bottom surfaces are combined with a voice coil loudspeaker voice coil 82 again, and voice coil loudspeaker voice coil 82 is just corresponding to the peripheries of vibrating membrane 81.Sound film 80 also is formed with fixing hole 83 in periphery isogonism place, and each fixing hole 83 corresponds respectively to the fixing hole 71 on the loudspeaker 70.Sound film stator 90 is the thin slice ring-type in addition, and its periphery also is formed with the fixing hole 901 corresponding to aforementioned fixation hole 71,83, so that sound film 80 is located in loudspeaker 70 bottoms.
This place will propose is the structure of aforementioned sound film 80, as shown in Figure 4, existing sound film 80 is to combine with voice coil loudspeaker voice coil 82 after moulding again, its middle pitch film 80 itself is to utilize mould compression moulding with cloth behind coating resin, glue together these voice coil loudspeaker voice coils 82 in sound film 80 bottoms corresponding to vibrating membrane 81 periphery places subsequently, because it is very high that the degree of balance of 81 pairs of vibrations of sound film requires, so voice coil loudspeaker voice coil 82 all must keep identical bonding tightness with sound film 80 on each angle.
Voice coil loudspeaker voice coil 82 itself is a winding coil on a paper ring again, because of the paper ring is coated with grease, so when combining with sound film 80, need the grease of paper ring periphery is ground off, and should polish, so that be bonding on fifty-fifty on the sound film 80 as far as possible.Although it is complicated as before that sound film 80 and voice coil loudspeaker voice coil 82 combine preceding preparation, but still can not avoid flaw to produce.Owing to combine at present still the stay in manual work stage of sound film 80 with voice coil loudspeaker voice coil 82, therefore when gummed, glue consumption all can't accurately be controlled, so sound film 80 combine with the ring-type of voice coil loudspeaker voice coil 82 be in some angle may be big because of glue consumption, and voice coil loudspeaker voice coil 82 peripheries are closely attached on sound film 80 bottom surfaces really, so form bonding state more closely, in addition a little angles then may be few because of glue consumption, and voice coil loudspeaker voice coil 82 peripheries are not adjacent to fully with sound film 80, and its conjugation is comparatively loose.Sound film 80 that this kind conjugation degree of tightness differs and voice coil loudspeaker voice coil 82 are when work, and it will produce bigger amplitude in conjunction with ravelled spot, because Oscillation Amplitude is big and frequent, after use a period of time, this will split in conjunction with ravelled spot, and can't normal articulation.From the above, the sound film and the voice coil loudspeaker voice coil of existing loud speaker are not only complicated at its combined process, and exist product fraction defective height and useful life low shortcoming.
The utility model purpose is to provide a kind of sound film voice coil loudspeaker voice coil of loud speaker, and the sound film that it can effectively overcome existing loud speaker combines difficult and the high shortcoming of fraction defective with voice coil loudspeaker voice coil.
To achieve these goals, its technical scheme mainly is to adopt one-body molded mode to constitute a sound film with suitable material, this sound film is formed with dome-type vibrating membrane in centre, its characteristics are: this sound film bottom surface is formed with a voice coil loudspeaker voice coil ring in vibrating membrane periphery place, is arranged with coil on the voice coil loudspeaker voice coil ring and constitutes a voice coil loudspeaker voice coil.
This sound film is formed with the side plate of big thickness in periphery.
The utility model compared with the prior art advantage and good effect is very obvious.The utlity model has following advantage as can be known by above technical scheme:
1. technology is simple: because the utility model is to adopt integral forming method to constitute with homogenous material, and form vibrating membrane, voice coil loudspeaker voice coil ring simultaneously in sound film table, bottom surface, winding coil on the voice coil loudspeaker voice coil ring again is with can constituting voice coil loudspeaker voice coil, so its manufacture process is very simple and can ensure the quality of products.
2. simplification member: the thickness of sound film side plate of the present utility model again is thicker, to replace the sound film stator in the conventional loudspeakers, therefore when being assembled into loud speaker, can omit this sound film stator.
3. structural strength ideal: the utility model is that the mixture one with plastic material or itself and glass fibre constitutes the sound film, and the more traditional sound film of its structural strength is good, can effectively prolong the useful life of sound film.
Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
Fig. 1 is a three-dimensional cutaway view of the present utility model.
Fig. 2 is a face upwarding stereogram of the present utility model.
Fig. 3 is the exploded view of existing loud speaker.
Fig. 4 is the exploded view of existing sound film and voice coil loudspeaker voice coil.
Relevant structure of the present utility model is partly please at first consulted Fig. 1.It mainly is to adopt one-body molded mode to form a sound film 10 with plastic material, this sound film 10 slightly is UFO-like, it is formed with a thinner thickness and is dome-type vibrating membrane 11 in centre, peripheral then be the side plate 12 that extends with horizontal direction, the bigger thickness of these side plate 12 tools, its peripheral appropriate location is formed with shrinkage pool 13 respectively, for fixing usefulness.
The side plate 12 of sound film 10 is formed with two through holes that radially run through 15 respectively in suitable angle place again, is equipped with a lead 16, two leads 16 medial extremitys therebetween respectively and is with the coil of winding subsequently on the voice coil loudspeaker voice coil ring 14 to be connected, and its outboard end is then for connecting signal source.
Consult shown in Figure 2, sound film 10 together with voice coil loudspeaker voice coil ring 14 one-body molded after, promptly in these voice coil loudspeaker voice coil ring 14 winding coils 17, coil 17 two ends are connected with lead 16 on the side plate 12 respectively subsequently, and coil 17 promptly constitutes a voice coil loudspeaker voice coil with voice coil loudspeaker voice coil ring 14.
Moreover, aforesaid sound film 10 is with the one-body molded formation of plastic material, the temperature resistant capability that adds forte film 10 as need, can utilize the mixed material of plastic material and glass fibre to constitute the sound film, with the sound film that this kind material constitutes, more than its heatproof Du Keda 100 degree Celsius, and owing to add glass fibre, so its hardness height, and have than the better structural strength of general sound film.
