Abstract
The utility model relates to a speaker that consists of a magnetic circuit system, a voice coil, a vibrating system and an auxiliary system. The magnetic circuit system consists of a magnet, a central magnetism-conductive column, an upper magnetism-conductive plate and a lower magnetism-conductive plate; the voice coil consists of an enamel wire and a framework; the vibrating system consists of a paper diffuser and a positioning support; and the auxiliary system consists of a diffuser frame and a blank holder; the framework is made of silicon-containing kraft paper; the thicker paper of the paper diffuser is provided with a silica gel coating; and the positioning support is made of silicon-containing fiber cloth. Because the three main components in the vibrating system are provided with the silica gel coating on the surface, the speaker has the characteristics of no moisture, excellent temperature and humidity resistances, and high toughness. The physical properties of the paper or the fiber cloth can not be changed as a result of the moisture or the temperature changes. And the speaker can effectively overcomes the adverse effects brought by the change of environmental temperature and moisture, and has the advantages of high working sensitivity, excellent stability, long service life for effective work, and so on. Moreover, the speaker has high practicality.
Description
Technical field
The utility model relates to a kind of electro-acoustic element, the loud speaker of particularly a kind of excellent performance, long working life.
Background technology
Loud speaker is used for stereo set morely, it is a kind of device that utilizes the electromagnetic viscosimeter principle to cause the object vibration sounding, main body is by magnetic circuit system, vibrational system and auxiliary system are formed, comprise on the magnetic circuit system and be provided with magnet, the center conducting magnetic column, upper conduction magnetic board and following magnetic conductive board, comprise in the vibrational system and be provided with voice coil loudspeaker voice coil, cone and locating branch slice, voice coil loudspeaker voice coil is made of enamelled wire and skeleton, comprise the basin frame in the auxiliary system, flanging, traditional loudspeaker voice coil skeleton by layers of kraft paper around forming, cone is by the integrated poured moulding of paper pulp, and locating branch slice is filled the post of by cotton or chemical fabric.Because speech coil framework and cone all are the papery goods without any processing, make moist easily and temperature tolerance poor, the physical property of papery is subject to airborne humidity and influence of temperature variation, cause influencing speaker product job stability in use, also can influence working life when serious, in addition, locating branch slice by cotton or chemical fabric without any processing, directly fill the post of, equally also there is the problem that is subject to temperature and humidity variable effect speaker operation stability, thereby the ubiquity working sensitivity is low, the drawback that poor work stability and useful working life are relatively shorter, 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, provide a kind of working sensitivity height, good operating stability and useful working life long novel loud speaker.
Loud speaker main body of the present utility model is by magnetic circuit system, vibrational system and auxiliary system are formed, comprise on the magnetic circuit system and be provided with magnet, the center conducting magnetic column, upper conduction magnetic board and following magnetic conductive board, comprise in the vibrational system and be provided with the voice coil loudspeaker voice coil that constitutes by enamelled wire and skeleton, cone and locating branch slice, comprise in the auxiliary system and be provided with basin frame and flanging, voice coil loudspeaker voice coil, cone and locating branch slice are fixedly installed on the basin frame, be characterised in that: described skeleton is made by adding silicon brown paper, the ground paper of described cone is provided with silica-gel coating, described locating branch slice is made by adding silica fibre cloth, and wherein: the described silicon brown paper that adds is made of brown paper and surface silicon gel coating; The described silica fibre cloth that adds is made of fiber cloth and surface silicon gel coating.
The utility model loud speaker based on above-mentioned design, because the skeleton on the voice coil loudspeaker voice coil adopts the silicon brown paper that adds of band silica-gel coating to make, cone is made by the ground paper of band silica-gel coating, locating branch slice is made by adding silica fibre cloth, make the big main member of three in the vibrational system all have nonhygroscopic, temperature tolerance and moisture-proof are all good, and the characteristics that toughness is strong, can not take place in the course of the work because of being subjected to humidity or difference variation to produce the situation of the physical property change of papery or fiber cloth matter, thereby guarantee to have higher and stable working sensitivity, compare with the loud speaker of prior art, can effectively overcome the harmful effect that the humiture variation brings in the environment, obviously has the working sensitivity height, advantages such as good operating stability and useful working life are long have very strong practicality and valuable market application foreground.
