A lawyer walks into a bar and sits down next to a drunk who is closely examining something held in his fingers. The lawyer watches the drunk for a while till he finally gets curious enough to ask what it is.

"Well," said the drunk, "it looks like plastic and feels like rubber."

"Let me have it," said the lawyer. Taking it, he began to roll it between his thumb and forefinger, examining it closely. "Yes," he finally said, "it does look like plastic and feel like rubber, but i don't know what it is. Where did you get it?"

"From my nose," the drunk replied.

Edison patent

In 1907, Thomas A. Edison was issued a patent for a "Diaphragm for Talking-Machines" (U.S. No. 855,562) that "will be readily responsive to vibrations of comparatively great amplitude." The invention comprised a duplex diaphragm made of at least two disks, each of which is radially sloted so that each disk constitutes a series of reeds. By staggering the slots of the disks, a continuous surface is presented for actuating the sound waves. The disks, made of mica about one-thousandth of an inch thick, are cemented together with an elastic cement, such as a solution of gum rubber.
