The sound produced by the speaker happens because the speaker is
driven
by a single complex waveform, thus there is a single source for the
sound.
The sound that comes from a train whistle is generated by the whistle,
and
the motion imparted to the whistle comes from the train's motion, two
separate sources.
** WRONG !!!
There is only one source of sound in both cases.
Case 1 = the cone.
Case 2 = the whistle.
If you move the whistle back and forth in a manner
approximating that of a speaker cone, you still have two sources, the
whistle's sound and the mechanical vibration of the whistle, if you
mount
the whistle on the speaker cone, you have two sources, that driving the
cone
and that coming from the whistle.
** I told you to lay off that damn weed !!
None of those approximates in any way, or
is a valid anology for a loudspeaker producing a complex waveform that
comes
from only one source, the complex electrical waveform driving the
speaker
motor.
** The SOURCE source of any sound is the vibrating object or air column.
All the other anologies have two sources, one for the low frequency
motion and one for the high frequency sound,
** Simply not relevant.
NOT a valid anology for what
happens when a speaker reproduced a complex waveform. If you don't get
that,
then perhaps it is you who should "lay off the weed".
** There is nothing rational anywhere in your posts to get.
You aren't going to
get it until you can differentiate that which comes from two or more
separate simple driving sources and that which comes from a single
complex
driving source
** Totally false distinction.
It exists only in the words.
BTW, I never said anything about a cone's motion being prodiuced by
sound.
I said "a speaker reproducing a complex waveform".
** Quote:
" Even moving the whistle back and forth in approximation of a
moving speaker cone is not a valid anology, because the whistle's back
and forth motion is not generated by the sound coming from the whistle,
as
it would be in a speaker reproducing a complex waveform. "
** Yes you did, then deceitfully snipped it.
In the first place, I don't go drugs of any kind, including weed and
alcohol, and in the second place if you don't see the difference between
providing all forms of motion involved (whether they produce sound or not)
with one complex source, and providing the different forms of motion
(whether they produce sound or not) with multiple simple sources, then any
conclusion you may come to is going to be fundamentally flawed, and all your
flippant answers aren't going to change that.
