Abstract
A membrane for an electro-acoustic transducer comprised of at least one elastomer layer made using spray coating of a liquid elastomer solution is provided. The at least one layer of elastomer is made by spraying a 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.
Claims10
A membrane for an electroacoustic transducer, the membrane comprising one or more spray-coated layers of an elastomer.
A membrane for an electroacoustic transducer, the membrane comprising one or more spray-coated layers of an elastomer, the membrane being manufactured by a method comprising the steps of:
- placing a component of the electroacoustic transducer into a recess on a mold having a desired membrane geometry, the recess being configured to accept the component of the electroacoustic transducer;
- spray coating one or more layers of a liquid elastomer solution on the mold;
- allowing the liquid elastomer to cure;
- and
- removing the cured elastomer in the shape of the membrane off the mold, wherein the component of the electroacoustic transducer is adhered to the cured elastomer after the removal step without the use of an adhesive.
A membrane for an electroacoustic transducer, the membrane comprising two or more spray-coated layers of an elastomer, the membrane being manufactured by a method comprising the steps of:
- spray coating one layer of a liquid elastomer solution on a mold having a desired membrane geometry;
- allowing the liquid elastomer to cure;
- repeating the spray coating and curing steps one or more times until the thickness of the membrane is a desired thickness;
- and
- removing the cured elastomer in the shape of the membrane off the mold.
