Because there are so many types speaker (speaker), a tapered speaker (speaker), ball (horn), the trumpet loudspeaker (horn), belt type speaker (speaker), static speaker (speaker), etc., each speaker (speaker) unjust principle, different forms, and the processing method, selection of material and each has its own characteristics.

Speaker (speaker) manufacturing involves the metal processing industry, chemical industry, papermaking, polymer materials, magnetic materials, natural materials and synthetic materials, as well as to the nearest aerospace materials, process, materials processing, the universality and diversity. This requires a multi-disciplinary, multi-disciplinary knowledge of the technical staff, or the support of multi-disciplinary talents in the manufacturing of speakers (speakers).

The performance of the material and the change of the processing method will cause the speaker (loudspeaker) electroacoustic performance and the change of sound quality. Take the paper basin speaker (speaker) as an example, in the same shape and geometry condition, possible: the change of pulp material; Changes in pulp tree species, chemical composition and origin; Changing of pulp and slurry degree (rapping); The change of sizing agent of pulp; The change of the proportion of glue sizing agent; The change of the fishing method; Change of heat pressure method, etc. Any change in any element of such a process may lead to a change in speaker performance and sound quality. Therefore, these processes themselves form a multivariate, multifactor system, and these factors form a complex situation, which is difficult to make intuitive judgment.

After the diaphragm and speaker are made, the process changes are difficult to detect and correct.

The conical speaker (speaker) is bonded with adhesive, which not only affects the bonding strength, but also affects the sound performance of the speaker.
