This bizarre phonograph, employing a record and turntable in the form of a truncated cone, was patented by Louis P. Valiquet, of Zonophone fame. One advantage was said to be that the record was less likely to slip on the turntable than a standard flat disc.

Emile Berliner’s device for increasing volume, employing six synchronized turntables. A later “improvement” stacked the turntables vertically.

F. F. Shanks of Chicago patented this reproducer-less device consisting of an extended rod that carried the sound vibrations directly from the stylus to an attachment of the user’s choosing (the filing mentions a snare-drum head, banjo, or other stringed instrument), which served as a resonator.

A more direct approach to musical-instrument-as reproducer, in this case a complete violin. A version of this machine was actually manufactured in France.

For when the “just stuff a sock in it” approach won’t do, here’s a marvelous piece of German over-engineering. This sadistic-looking device was patented by Albert Conze of Berlin and specified a muffler-ball of leather, cork, or felt. Edison later employed the same general idea in his Diamond Disc machines, but with the adjusting mechanism neatly tucked away below the bedplate.
