I partially understand how a speaker works
and in order to decrease its audio output I will have to remove or
partially
remove the paper which joins the core to the outer body - but will it still
vibrate ?. Any suggestions would be most welcome.
Hi John,
The most probable answer is no as the paper cone centralises the voice coil
within the gap between the magnet poles. Without this centring effect the
voice coil would just jam against the magnet poles and the output would be
extremely low. This effect is noticeable when the voice coil is placed off centre
by the paper cone. A low and distorted output is all that occurs as has been
noted on some K2 with damaged speakers.
Another solution may be to use one of the old type headphones with a metal
diaphragm under the screw on earpiece. Another way would be to convert the
morse signal to some visual form such as for displaying on an oscilloscope or use
a morse reader. Compared to the human brain however, all the morse readers I
have tried come off very much second best.
