pulmonary diaphragm
thoracic diaphragm
- Any of various membranes or sheets of muscle or ligament which separate one cavity from another.

contraceptive diaphragm
-
A flexible membrane separating two chambers and fixed around its periphery that distends into one or other chamber as the difference in the pressure in the chambers varies.
There also were five broken panes of glass on the two huge, rubberlike diaphragms that equalize air pressure within the dome as the artificial atmosphere expands and contracts with temperature variations, he said.
1994 May 4, “Two Former Biosphere Workers Are Accused of Sabotaging Dome”, in The Associated Press:This is effected by a novel and ingenious application of two flexible diaphragms—the upper of which, being acted upon by the lower, is pulled down on its seat, and forms a perfectly leakless joint.
1847, editorial staff, “Improvement in Water Taps, Cister Valves, &c. ”, in Scientific American, series 1, Volume 3, Issue 9, page 68:
-
(qualifier:acoustics) In a speaker, the thin, semi-rigid membrane which vibrates to produce sound.
acoustic diaphragm
- A thin opaque structure with a central aperture, used to limit the passage of light into a camera or similar device.
-
A permeable or semipermeable membrane.
The mass of liquid transported through a porous diaphragm in a given time is directly proportional to the current.
1921, Wilder Dwight Bancroft, Applied Colloid Chemistry: General Theory, page 207:
- A floor slab, metal wall panel, roof panel or the like, having a sufficiently large in-plane shear stiffness and sufficient strength to transmit horizontal forces to resisting systems.
