Association of industry of Chinese electron component Wang Runli of secretary-general of branch of electroacoustic parts of an apparatus

Regard seeing and hearing as the core of the product, electroacoustic parts of an apparatus gets more and more attention. As we have learned, our country has been developed by oneself mastered arrive from component of electroacoustic parts of an apparatus the total production technology of finished product, formed electroacoustic parts of an apparatus to produce industrial system and complete industrial chain, but the core competition ability that should form homebred and electroacoustic parts of an apparatus truly, take very long way even.

Fundamental category looks: Take software equipment and GB seriously

The development of electroacoustic parts of an apparatus and component CAD, CAT and CAM technology applies

Electroacoustic parts of an apparatus always can use the method of equivalent circuit, apply electronic circuit principle, in different frequency paragraph inside analytic circuit is characteristic, realize electroacoustic parts of an apparatus good reputation function and push the performance that judges component of electroacoustic parts of an apparatus to ask. When the analysis we always can be the software equivalent of electroacoustic parts of an apparatus 3 parameter: Damp (Rm) , compliance (Cm) and quality (Mm) , ρ of density of the E of Yang model quantity that these 3 parameter basically rely on software material itself, material and internal resistance Buddhist nun coefficient, concern with the appearance of software and treatment means again at the same time. Software appearance is abnormity, should determine correctly the Yang model quantity of its software and internal resistance Buddhist nun are very difficult, and once most Buddhist nun of fundamental E, ρ , internal resistance is offerred not accurate, so the Rm that regards circuit as the foundation, Cm, Mm does not talk to go up accurate, nature of circuit analysis error is met very big. Apply CAT technology to check the physical parameter such as the E of loudhailer software, the magnetic circuit design that uses CAD to undertake loudhailer, medicinal powder the mechanical design of hot design and component, realize the CAD design of loudhailer unit then. At the same time also but according to brace up the physical parameter such as film, the sample that makes drafts in computer upper mould, can foretell the each function index such as noise of frequency of indication finished product. place indication index and original design ask to compare, book a requirement to achieve, the parameter of modification software, draft in computer upper mould again, the course is revised for many times, each function that makes simulation software satisfies finished product place completely to need asks. Again the function index according to simulation software, use CAM treatment and CAT test, will realize the software that wants requirement performance.
