A membrane () for an acoustic device including an electrical conductor () integrally formed within the membrane (). The integrally formed electrical conductor () may be net-shaped and may be formed between two or more layers of membrane material. The integrally formed electrical conductor () may be electrically connected to the voice coil in an acoustic device, wherein the integrally formed electrical conductor () is adapted to provide an electrical signal to the voice coil during operation of the acoustic device. Additionally or alternatively, the integrally formed electrical conductor () may be electrically connected to one or more electrical and/or electronic components () affixed to the membrane ().

Electrodynamic loudspeaker membrane with internally molded electrical connection

A frameless audio transducer for mobile applications is provided. The invention relates to an audio transducer realized as speaker to transduce an electrical audio signal into acoustic sound or realized as receiver to transduce an acoustic sound into an electrical audio signal, which audio transducer is realized without a frame to align and fix the other parts of the audio transducer. The frameless audio transducer further includes coil lead support structures to reduce stress on the coil leads during operation.

Frameless audio transducer for mobile applications including optionally supported coil wire and leads

A speaker and method for making the same are provided. The speaker includes a permanent magnet and a coil disposed about a first axis around the permanent magnet, the coil being configured to move along the first axis. The speaker further includes a membrane attached to a top surface of the coil and a stabilizer contacting at least one of an internal surface, an external surface, and a bottom surface of the coil, and configured to limit movement of the coil relative to a second axis perpendicular to the first axis.

Speaker with a coil stabilizer and method for manufacturing the same

An audio system that comprises an electro-acoustic transducer mounted onto a housing that forms a resonance volume which is at least partially filled with sound absorbing material, wherein the housing is realized with a deep-drawn foil at least partially filled with grains of the sound absorbing material.
