Abstract
The utility model relates to a practical loudspeaker voice coil which consists of a lacquered wire, a framework and reinforcing paper. The utility model is characterized in that siliceous compound gluewater with the moisture prevention and temperature resistance functions is coated on the lacquered wire, the framework and the reinforcing paper, so the practical loudspeaker voice coil which adopts the components has excellent moisture prevention and temperature resistance functions. Compared with the loudspeaker which adopts an ordinary voice coil in the prior art, the utility model can obviously overcome the adverse effect caused by temperature and humidity change in the environment, and has the particular advantages of high rigidity, high work sensitivity, high work stability, long service life and the like.
Description
Technical field
The utility model relates to a kind of electro-acoustic element, the practical loudspeaker voice coil of particularly a kind of protection against the tide and heat resistance excellence, long working life.
Background technology
Loud speaker is a kind of electronic device that utilizes the electromagnetic viscosimeter principle to cause the object vibration sounding, loud speaker agent structure more complicated, include magnetic circuit system, vibrational system and auxiliary system, wherein: magnetic circuit system includes magnet, center conducting magnetic column and magnetic conductive board up and down, include voice coil loudspeaker voice coil, cone and locating branch slice in the vibrational system, comprise basin frame, flanging in the auxiliary system.And wherein vitals of most critical is a voice coil loudspeaker voice coil, and it is the heart of loud speaker, has directly determined the quality of watt level, working sensitivity and the tonequality of loud speaker.
Loudspeaker voice coil in the conventional art is made of enamelled wire and skeleton, skeleton is made by materials such as brown paper, polyimides, because speech coil framework system is without the goods of any processing, be subjected to airborne humidity and influence of temperature variation easily and moisture resistance, temperature tolerance is all relatively poor, thereby cause influencing speaker product in use low, poor work stability of ubiquity working sensitivity and the relatively shorter drawback of useful working life, consider from economy and point of view of practicability, all owe desirable.
Summary of the invention
The purpose of this utility model be to overcome the prior art loud speaker low, poor work stability of ubiquitous working sensitivity and the relatively shorter drawback of useful working life, a kind of practical loudspeaker voice coil that helps to improve speaker operation sensitivity, job stability and useful working life is provided.
Practical loudspeaker voice coil main body of the present utility model is made of enamelled wire, skeleton and reinforcement paper, be characterised in that the loudspeaker voice coil main body is arranged to circle or ellipse, wherein: on the described enamelled wire coated be provided with have protection against the tide, the siliceous compound adhesive water layer of heatproof function; Coated is provided with and has protection against the tide, stirs in the siliceous compound adhesive water layer of heatproof function or the framework material and directly make after adding described siliceous compound glue with protection against the tide, heatproof function on the described skeleton surface; On the described reinforcement paper coated be provided with have protection against the tide, the siliceous compound adhesive water layer of heatproof function.In addition, according to the loudspeaker design needs, described coil both can be formed by the direct coiling of enamelled wire, also can be respectively on the described skeleton or on the reinforcement paper separately coiling form, perhaps coiling forms on the combination of skeleton and reinforcement paper.
In addition, described siliceous compound glue with protection against the tide, heatproof function is mixed and made into silicon materials respectively by a kind of glue or multiple glue in allyl resin, poly-imines, polyamide, polyamine fat, polyester, polyethylene, epoxy, polyimides, polyester imines, the phenol.
Based on the practical loudspeaker voice coil of the utility model of above-mentioned design, owing to constitute the skeleton of voice coil loudspeaker voice coil, enamelled wire and reinforcement paper have all been taked protection against the tide, the heatproof special processing, make the practical loudspeaker voice coil of the utility model that adopts these parts to make have excellent protection against the tide, the heatproof function, can not take place in the course of the work because of being subjected to humidity or difference variation to cause the situation that physical property changes, thereby guarantee that the loud speaker that adopts the practical loudspeaker voice coil of the utility model to make has preferable tonequality, stable working sensitivity and long working life, compare with the loud speaker of the common voice coil loudspeaker voice coil of employing of prior art, obviously have and effectively to overcome the harmful effect that the humiture variation brings in the environment, rigidity is stronger, working sensitivity is higher, distinct advantages such as the better and working life of job stability is longer, thereby have very strong practicality and valuable market application foreground.

Accompanying drawing is the basic structure schematic diagram of the utility model embodiment.
Among the figure:
1. enamelled wire 2. skeletons 3. reinforcement paper
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and exemplary embodiments.
In the accompanying drawings, practical loudspeaker voice coil main body of the present utility model is made of enamelled wire 1, skeleton 2 and reinforcement paper 3, it is rounded or oval to be characterised in that the loudspeaker voice coil main body is provided with, wherein: on the described enamelled wire 1 coated be provided with have protection against the tide, the siliceous compound adhesive water layer of heatproof function; Described skeleton 2 surfaces go up coateds be provided with have protection against the tide, the siliceous compound adhesive water layer of heatproof function; On the described reinforcement paper 3 coated be provided with have protection against the tide, the siliceous compound adhesive water layer of heatproof function.
In addition, described siliceous compound glue with protection against the tide, heatproof function is mixed and made into silicon materials respectively by a kind of glue or multiple glue in allyl resin, poly-imines, polyamide, polyamine fat, polyester, polyethylene, epoxy, polyimides, polyester imines, the phenol; Described skeleton 2 is directly made after also can stirring in framework material and adding described siliceous compound glue.
