A loudspeaker comprises an enclosure, at least one dynamic driver mounted in the enclosure, and at least one porous monolithic block. The at least one porous monolithic block comprises a plurality of pores and is mounted within the enclosure.

Loudspeaker, mobile device and method of manufacturing a loudspeaker

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.

Loudspeaker membrane with spray-coated elastomer layer

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.

A method of thinning a multilayer laminate material used for a membrane stiffening plate is provided to obtain a membrane stiffening plate having a thickness less than currently known in the art. The method provides for a significant reduction in the thickness of a membrane stiffening plate and provides for a mechanism to tune the cut-off frequency of a loudspeaker on which the membrane stiffening plate is used.

The present invention discloses a vibration membrane assembly for a speaker, a method for producing a vibration membrane assembly and a speaker. The assembly comprises a vibration membrane and a vibration membrane carrier ring. The method comprises providing a first thermal molding die having a molding side, the molding side having a profile which is complementary to that of the second side of the vibration membrane assembly, putting the vibration membrane carrier ring onto the molding side of the first thermal molding die and laying a vibration membrane blank onto the vibration membrane carrier ring to bring the vibration membrane blank in contact with the vibration membrane carrier ring, applying a pressure to the vibration membrane blank against the vibration membrane carrier ring to nest and fix the vibration membrane blank on the vibration membrane carrier ring to form the vibration membrane assembly, removing the pressure off the vibration membrane blank and separating the vibration membrane assembly from the first thermal molding die.

A gas adsorbing material is provided. Specifically, there is provided a molded matrix of a plurality of spherically-shaped gas adsorbing material. The individual spheres comprise particles of a highly porous gas adsorbing material and a binder. The plurality of spheres are mixed with a second binder material and molded into a desired shape for use in the back volume of an acoustic transducer such as a loudspeaker device, a microphone or a balanced armature receiver.
