A large cone may be inserted in the mouth-piece B, for collecting extraneous sounds andcausing them to move the diaphragm. This apparatus is useful for giving motionto clocks and other small apparatus requiringminute power. I claim as my invention— A vocal engine consisting of a diaphragm orother body capable of being set in motion bysound-waves, a shaft, and reciprocating mech-anism, substantially as and in the manner setforth.
