Hi, I am alittle miffed regarding the 'ribbon speaker'
Can anyone shed light on the subject or at least know of a good place to read.

Thanking you in advance

Pluck a thick blade of grass.
Place between your two thumbs
Place your two thumbs to your lips and blow.


The sound you hear is the grass vibrating.

Now assume the blade of grass is a charged thin metal strip, and your two thumbs are electromagnets.

As the variable frequency signal from the amp varies the properties of the charged wire it vibrates at different frequencies and makes..

Sound.

Mudcat,

That's a great explanation. I have also always wondered how they work.

Ribbon Driver: A type of loudspeaker transducer that uses a thin metallic film suspended between two magnets as the diaphragm. A true ribbon driver differs from a standard planar transducer in that the diaphragm is attached only at the ends. Thus, a true ribbon driver is very delicate, but is able to move very quickly and can produce high frequencies very accurately.

This is from Parts Express it can be found at:

Yes, but that Part Express definition seems to add a bit of irrelevant information, that may seem misleading in part. A 'true' ribbon driver may be able to move very quickly and produce high frequencies very accurately, but so can plenty of examples of dynamic tweeters and planar tweeter and bending mode drivers, etc.. At the same time, they left out the part about a 'true ribbon' requring a transformer to be attached between the amplifier and driver, due to the extremely low impedance of a 'true' ribbon tweeter. :D
