Pique the Geek 20110724: Loudspeakers Part II

I was running out of time last week as the publication hour was neigh, so I was not able too include everything that I wanted to include.  In the meantime, I have gained some additional information that refutes one of the points that I made.  Remember, The Geek likes to be corrected when he is wrong.  We shall get to that after the fold.

This installment has to do with some experimental or otherwise not widely used loudspeaker designs, but also something much more personal to me.  It has to do with a good friend from almost 40 years, and his interaction with Paul Klipsch and others involved in the company.

First we shall make the correction, then talk about other loudspeaker designs, and then the more personal stuff.  Ready to go?

Pique the Geek 20110717: Loudspeakers

In electronics, a loudspeaker is what most people just call a speaker, the device that converts electrical signals to sound.  They can range from very simple to very complex designs, with variations in cost from just a few cents to thousands of dollars.

All practical loudspeakers are electromechanical devices, using an analogue electrical signal to make the loudspeaker components to move in such a manner as to in turn move air (usually, although other media can be used for purposes other than human perception) and thus make a sound.  For human hearing, air is almost always the medium used.

Loudspeakers are one of the few modern electronic devices that are analogue only.  In other words, a truly digital loudspeaker does not exist except in a few research laboratories and they are not very good.  It is interesting to me that the final stage of reproducing sound is firmly rooted in the 19th century insofar as basic technology in concerned.  This discussion is limited to electromechanical loudspeakers.  Purely mechanical ones are much older than electromechanical ones.
