Abstract: An electro-acoustic transducer includes a diaphragm and an electro-magnetic motor for driving motion of the diaphragm. The electro-magnetic motor includes a magnetic circuit that includes a first Rare earth-Iron-Boron (REFeB) magnet. The REFeB magnet includes a major phase and a grain boundary rich rare earth phase. A heavy rare earth element (HREE) is diffused into the first REFeB magnet through the grain boundary rich rare earth phase.

Abstract: Articles and methods are provided for miniature acoustic transducers having highly compliant suspension systems despite their small size. In various examples the suspension system is molded of a liquid silicone rubber (LSR) and is molded in an interior cavity geometry that includes and apex radially offset and/or axially offset from a desired cured position of an apex of the suspension.

Abstract: Articles and methods are provided for miniature acoustic transducers having highly compliant suspension systems despite their small size. In various examples the suspension system is molded of a liquid silicone rubber (LSR) and is molded in an interior cavity geometry that includes at least one of a radial offset or an axial offset from a desired geometry of the suspension.

Abstract: A method for tissue augmentation in a mammal is provided having injecting a polymer at a tissue site in need of augmentation and having a tissue temperature, the polymer having repeating peptide monomeric units selected from the group consisting of nonapeptide, pentapeptide and tetrapeptide monomeric units, wherein the monomeric units form a series of &bgr;-turns separated by dynamic bridging segments suspended between the &bgr;-turns, wherein the polymer has an inverse temperature transition Tt less than the tissue temperature, and wherein the polymer is injected as a water solution at coacervate concentration in the substantial absence of additional water. A kit containing the injectable bioelastic polymer and a syringe is also provided.
