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.
Claims11
A membrane for an electroacoustic transducer, the membrane comprising one or more spray-coated layers of an elastomer,
- wherein the membrane is affixed to one or more components of an electroacoustic transducer through curing of the one or more spray coated layers of an elastomer,
- wherein the membrane comprises more than one spray-coated layer of an elastomer, the layers being of different elastomer materials having different mechanical properties.
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:
- 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 layer of a liquid elastomer solution on the mold;
- 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,
- wherein the component of the electroacoustic transducer is adhered to the cured elastomer after the removal step without the use of an adhesive.
