Abstract
The present invention relates to a liquid fixed electrode of a capacity type loudspeaker. The present invention is characterized in that the electrode comprises a sealing insulating cavity body which is poured with liquid electric materials inside; the cavity wall of the cavity body is provided with a leading conductive body communicated with the liquid electric materials in the cavity body. The fixed electrode reduces the process difficulty and the material cost of fixed electrodes of capacity type loudspeakers, increases insulating performance and enhances performance indexes.
Description
Technical field
The present invention relates to the electroacoustic transducer technical field, relate to the fixed electrode of condenser loudspeaker especially.
Background technology
To the literature search of prior art, do not find direct identical any patent with the present invention.
In the technology before the present invention, the fixed plate electrode of condenser loudspeaker generally can be divided into two big classes:
The one, metallic plate external application insulating barrier electrode: be that (thickness is generally 0.5mm～1.5mm) and makes through punching repeatedly with the sheet copper of punch forming or aluminium sheet.The technology difficulty of copper coin or aluminium sheet perforated electrodes is: (1) must proofread and correct the deformation in the course of processing; (2) high-voltage breakdown for preventing that condenser loudspeaker when vibration vibrating diaphragm from producing near fixed electrode, thereby must make insulation processing to fixed electrode, problem is, make the edge in hole on the metallic plate can tolerate high pressure than difficulty, because most coatings all has surface tension.The approach that solves: generally be to adopt on the metallic plate fixed electrode, to precipitate insulating polymeric material.Technology difficulty and processing cost thereof have been increased thus.
The 2nd, apply copper insulation board perforated electrodes.Apply copper insulation board electrode and be the copper sheet of precoating on glass mat or resin plate surface, obtaining repeatedly the punch defective of fixed electrode of (this kind process program is that German ROLFRENNWALD proposed in its " full range capacitor formula loud speaker " paper in 1963) this deposited copper insulation board with the mode of punching one by one then is: repeatedly punch (1) must be with the plant equipment of precision, and the complexity and the processing cost of technology are higher; (2) glass mat that approaches or the mechanical strength of resin plate often are lower than the metallic plate of same thickness, thereby must increase thickness to guarantee necessary mechanical strength.Thus, cost just more becomes higher, and is much also more expensive than the metal plate perforation insulating electrode sometimes.
Summary of the invention
The objective of the invention is the deficiency that exists in the above-mentioned background technology in order to solve, it is simple to propose a kind of manufacturing process, with low cost, the liquid fixed electrode of the condenser loudspeaker that insulation property are superior.
The objective of the invention is to be achieved through the following technical solutions.A kind of liquid fixed electrode of condenser loudspeaker, its special character are the insulation cavitys that this electrode comprises sealing, and the insulated cavity perfusion in vivo has electrically conductive liquid material, on the wall of the chamber of cavity, be equipped with cavity in the electrically conductive liquid material conducting draw electric conductor.
The present invention is with the metal part in the liquid replacement background technology of conduction, replace insulating process complicated in the background technology with insulation cavity (being again the carrier of electrically conductive liquid material simultaneously), therefore, it has reduced the technology difficulty and the material cost of condenser loudspeaker fixed electrode, its insulation mode is better than background technology greatly, improve performance index, had good visuality.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is a stereogram of the present invention.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the B-B cutaway view of Fig. 2.
Fig. 5 is a K place partial enlarged drawing among Fig. 2.
Embodiment
As figure, the 1st, the cavity of insulation, it can be with comparatively cheap and have the plastics of good insulation characteristic to make.As adopt transparent plastics, it can well show novelty, and it is had intuitive preferably as scientific and technological teaching aid.Cavity can be the template on plane, also can be the plate of camber.Preferred embodiment adopts the template on plane.The cavity internal cavity partly is cylindric or flat column or other irregularly-shaped hole constitute.Cavity is the non-leakage of sealing.
The 2nd, be fed into the conducting liquid in the chamber.The acquisition conducting liquid is very easy to, and as common water, its cost almost can be ignored fully.Improve its conductance as need, can add salt or any fuse salt in right amount.It is very low that its cost remains.As uncommon the colorful one conducting liquid that obtains, can add water-soluble coloured dyestuff in right amount to obtain abundant colors.Colour can be pleased people's vision, and is ornamental to increase it, and fabulous visuality is arranged during as scientific and technological teaching aid.
The 3rd, draw electric conductor, adopt the structure of electrode needle.In condenser loudspeaker fixed electrode technology, it is equivalent to the lead-out wire of conventional fixed electrode, and it only needs chromium plating copper wire or the stainless steel wire of a bit of about φ 1mm.As can be seen, its cost is low-down.
The 4th, sealing compound, purposes is the sealing electrode needle of drawing, with antiseep, adopt common sealing compound also can, its cost also is low-down.
The 5th, sound transmission aperture, sound transmission aperture can be uniform arbitrary shapes.But, bar hole as shown in the figure is proved to be most suitable through experiment.The reference value of perforated area is: 40～50%.
The 6th, the installation frame of preferred embodiment, will insulate cavity and installation frame of the preferred mode of implementing to adopt the polycarbonate injection mo(u)lding is injection molded into a coenosarc.Certainly, in other design, can design other mounting means as required.
Preferred embodiment figure has given the section of A-A (laterally) B-B (vertically), and the details K of electrode needle socket and electrode needle sealing compound is amplified processing.Need not change to this figure and can realize the present invention, make a complete liquid solid electrode.
