For quality reasons, moving-coil drivers must be designed with effective cooling measures so that the coil temperature excursion is minimized. The coil can shed heat by radiation and by conduction. Conduction is limited because the coil former is attached only to the cone and the spider. Most spiders are thermal insulators, as are most cone materials, with the notable exception of aluminium cones,which can contribute significantly to coil colling if the attachment of the coil former to the cone is designed as a thermal path.
Yes,this place is a good site to communicate each other.
Thank you again for your concepts about the design.
We would love to exchange ideas with foreign engineers and experts too.
Personely, I will say for a lot of Chinese engineers there are only ways to follow or copy, I am sorry to say that.
One big reason is the demand from marketing even some professors and experts including me to worry about trends.
But no way right now.
I prefer to discuss the issue with foreign experts in the same occupation. But it is not easy.
Before we say more, one thing is clear, that is there are all most same points of view in a lot of design questions.
For reasons of the enviroment protection and fully useage of material, I came here to do some knowledge sharing
among Chinese engineers. I guess it does work, even it is a little progress.
