Anvendelse af ferritmagneter i det akustiske felt
I det akustiske felt bruges ferritmagneter hovedsageligt i forskellige typer højttalere, såsom hovedtelefoner, øretelefoner, højttalere og mikrofoner. Specifikt bruges de til svingspolen, magneten og det magnetiske kredsløb. En af grundene til, at ferritmagneter er meget udbredt i den akustiske industri, er deres fremragende akustiske egenskaber, herunder høj magnetisk permeabilitet, lavt tab og høj mætningsfluxtæthed.
Ved udformningen af svingspoler bruges ferritmagneter normalt som permanente magneter. Deres stærke magnetfelt kan give en stabil magnetisk kraft til systemet, hvilket er en vigtig faktor i den akustiske enheds følsomhed og impedans. Derudover sikrer ferritmagnetens høje koercitivitet, at svingspolen har en stærk genoprettelseskraft og en hurtig respons, hvilket er essentielt for lyd i høj kvalitet.
Brugen af ferritmagneter i det magnetiske kredsløb har gradvist erstattet andre materialer på grund af deres fremragende magnetiske egenskaber og lave omkostninger. Ferritmagneter kan give et meget stabilt magnetfelt, hvilket er vigtigt for enhedens akustiske egenskaber. Sammenlignet med andre materialer har ferritmagneter højere magnetisk energi, hvilket kan forbedre systemets effektivitet.

Krav til størrelse, tolerance og ydeevne
Størrelsen og tolerancen af ferritmagneter, der anvendes i den akustiske industri, afhænger af den specifikke anvendelse og den nødvendige ydeevne af enheden. Generelt skal ferritmagnetens størrelse og tolerance være i overensstemmelse med enhedens designkrav for at sikre dens normale drift.
Ydeevnekravene for ferritmagneter, der anvendes i den akustiske industri, omfatter hovedsageligt de magnetiske egenskaber, mekaniske egenskaber og temperaturstabilitet. De magnetiske egenskaber af ferritmagneter er de vigtigste, herunder magnetisk fluxtæthed, magnetisk permeabilitet, koercivitet og magnetisk energiprodukt. De mekaniske egenskaber af ferritmagneter er også meget vigtige, herunder trækstyrke, bøjningsstyrke og trykstyrke.
Derudover er temperaturstabilitet også en vigtig faktor at overveje, når man bruger ferritmagneter i den akustiske industri. Ferritmagneter er kendt for deres fremragende temperaturstabilitet, men det specifikke temperaturområde er forskelligt for forskellige typer ferritmagneter.
Udsigterne for de vietnamesiske og indiske markeder på det akustiske område

Zhongke is committed to becoming a world-renowned supplier of permanent magnet material application solutions in the field of new generation consumer electronics and energy-saving home appliances.
The company's current production process of permanent ferrite magnets is as follows: the purchased pre-fired materials are mixed according to their own formula and ingredients, and after being ball milled by a ball mill, ferrite is produced through steps such as precipitation, wet pressing, sintering, and grinding. Body magnetic tiles, ferrite magnets and other finished products. The specific production process flow chart is as follows:
The strontium ferrite calcined material (the main component is SrFe12O19) is mixed with calcium carbonate, silicon dioxide, strontium carbonate, lanthanum oxide, cobalt oxide and other ingredients according to the formula ratio.
The raw materials are added with water and pulverized by a ball mill to form a slurry, which is placed in a sedimentation tower for precipitation.
The dehydrated material formed by precipitation is made into a green body through an automatic press in a normal air environment.
The raw body is sintered at high temperature into a mature body through a wet-pressed magnetic tile electric-fired roller kiln or a wet-pressed magnetic steel gas-fired roller kiln.
The cooked blank is processed by a fully automatic grinding machine processing line to form a finished product.
The magnetic properties, appearance, size and other indicators of the magnets are inspected, packed and put into storage.
The company has applied and improved a number of advanced technologies in the industry, such as high-performance ferrite slurry stabilization technology and secondary ball milling batching technology, which has solved the quantitative problem of material added in the preparation process. And we use double coupling dispersion and fine grinding to overcome the problems of slurry agglomeration and particle size distribution consistency. The performance of the slurry obtained in the ball milling process is more stable, which reduces the unit operating time of the ball milling equipment, improves product quality, and reduces production costs.
The company uses a unique new green release agent independently developed to prepare magnetic tiles. The new green release agent is an organic combination of microbial technology and surface release treatment technology, which can degrade oil molecules, reduce the oil content of the release agent, and restore the surface. active lipophilic factor. The product is combined with the surface release process, and the release effect of the magnetic tile is improved through a new release agent, and the surface finish of the blank is improved. The demoulding technology has the characteristics of simple preparation method and convenient application, and improves production efficiency.
By transforming the sintering preheating system equipment, the company reduces the water content of the sintered green body in the kiln, greatly reduces the waste rate caused by factors such as cracking and lack of oxygen during sintering, and improves the sintering density and mechanical strength of the product. Obtain good microstructure and magnet properties. The company has also realized the sintering base temperature that products with different performances can adapt to through formula adjustment. Products with different specifications, sizes and performances can be co-fired at the same temperature, which significantly improves the production efficiency of the sintering process. In addition, in terms of veneer loading and billet loading, the company has adopted a bulk stacking method that conforms to the company's product features of small shape and light weight after many tests, realizing heavy veneer loading, good sintering atmosphere, and high sintering yield. good effect.
By optimizing the parameters of grinding machines and other processing equipment and improving the process technology, the company has improved the consistency of product thickness to ≤0.02MM within L30MM and ≤0.04MM within L50MM, and has mastered the technology of three-phase motor magnets produced by grinding tooling. Breakthroughs have been made in technical difficulties in the industry, such as product precision and stable equipment performance, and certain innovations have been achieved in technology and equipment.
The company's magnetic tile products are developing in the direction of high efficiency, low consumables, and low energy consumption. For example, through atomic substitution and compound doping, the rare earth-free ZK-5B high-performance motor magnetic tile independently developed by the company reduces the coagulation of magnetic powder, improves the orientation effect, improves the material performance and reduces the production cost by using strong magnetic field to suppress and adding a double dispersant.
