     jy:  对!    轻敲下805的高音,就会有铝皮的声音,但不应叫谐振,应是它的主自振频声.谐振声应是付自振频声,这声比较弱,很少会听到.This means, every material has it's own character, in the industry, we
call it sound of identity. Can't avoid this identity no matter what kind of
material used. This identity usually comes out as a peak at certain
frequencies band width. We can apply some circuit to smooth it out. This circuit is actually a sort of filter but it has different names depends on
where it to be appeared.
    大提琴余音的明显起伏就是该弦的谐振. We don't call it resonant,
rather we call it harmonic in this case. That is why I told you, you don't even know how to use the right word to describe it. You might mislead others.
I understand what you wish to say. You are trying to express that the
string of the double bass's harmonics. This may count on two issues,
For one, whether the cone could produce the harmonic is the priority in
speaker design. Secondly, whether or not you amplifier or signal source
(in this case the CD player) could dig out the harmonic is another matter.
When considering high fidelity, we must consider as a whole and every
components in the system are responsible for the task.
    如果你喜欢铁皮声这是可以的.但这铁皮是很难做到有弹性的.很多时会做成正曲面或负曲面,这样它的自振频率很难控制.
    又得有对大防尘罩的弊病有同感的人,希望多点交流经验和看法.

madog:你只是不断提出疑问,却没有自己的观点,请提出你的论点,说出你的论据.

Sorry cannot write all the answer as there will be muuuuuucccchhh more
to write and it will be about at least ten time more than your writing.

Besides, I don't think you would be able to understand to what I write,
as you are just in the stage of primary school, not even middle school.

Sorry for my being straight, but this is the fact as all that you said is just
skin deep and most of the time is incorrect.

When I told to learn more theory, please go ahead, study hard, understand
the Theil and Small parameter, understand the function of the cone,
understand the function of the spider, voice coil, power, basket,
suspensons, Oh so many thing you have to understand.

Let me tell you what, go and get some books to read, after studying one
year then you look back to your article that you wrote today, then you will see what I mean.

I can only answer good questions but not answer to those even don't
know how to ask, that means I don't answer to stupid questions.

Sorry again, I didn't mean to ambarase you but as I told, speaker drivers
design is a real BIG TOPIC, the more simple it look, the more complicate
to design because there are lots of factors has to comprise in design.

Don't get mad, Man Gor,

Wish you all the best in your learning.
