Abstract
A method of manufacturing a membrane for an electro-acoustic transducer through spray coating of a liquid elastomer solution is provided. The method includes spraying the liquid elastomer solution, which may comprise a silicone, onto a mold having the desired membrane geometry, allowing the solution to cure and remove the membrane from the mold. The mold can be configured to hold other components of an electro-acoustic transducer that will be attached to the membrane after the curing step. Also provided is a membrane for an electro-acoustic transducer comprised of an elastomer and made using spray coating of a liquid elastomer solution.
