How to use this forum
You will find instructions on posting images (it's a pain) and getting the best out of this forum.
Possibly some form of high frequency loud speaker (tweeter), but I am not saying that with any confidence. What do you think it is? Where is it?

Looks like an annunciator or horn etc.

Wawa

It's a reverse loudspeaker.

The voice coil is attached to a weight while the relatively light magnet is mounted to a panel.  The recoil from moving the weight shakes the panel to which it is bolted, and the panel radiates the sound - or vibration.

"jogger" is a fair description.

OK, so I had some difficulty remembering the device that this discussion brought to mind.  After a couple of sleeps, it came to me.

It was the "Aura Interactor".  Possibly worth more now as a legacy item!

Wikipedia cites:

uses Aura's patented electromagnetic actuator technology to convert bass sound waves into vibrations
which of course, simply refers to one of the transducers under discussion here.







And I'm pretty sure I have (at least) one - somewhere.  :smiley-cool:
