摘要： Contemplated planar magnetic microphones have a magnet and diaphragm arrangement such that substantially homogenous vertical and high horizontal magnetic flux density is realized in the inter-magnet space. Most preferably, the diaphragm is disposed in the inter-magnet space and includes a voice coil covering a significant fraction of the active portion of the membrane. In further especially preferred aspects, the membrane is sufficiently strong and tensioned to allow a large elastic excursion in the inter-magnet space. Consequently, contemplated planar magnetic microphones provide exceptionally large dynamic range without compression and/or distortion and can be easily configured to operate in an environment that is subject to moisture, rain, or to even operate in a submerged environment. Moreover, contemplated microphones can be used as speakers at even high SPL without reconfiguration.

摘要： Contemplated planar magnetic transducers include a magnet and diaphragm arrangement such that substantially homogenous vertical and high horizontal magnetic flux density is realized in the inter-magnet space. Most preferably, the diaphragm is a tensioned polymer membrane in which the voice coil covers a significant portion of the active portion of the membrane, and the magnets are rare-earth metal-type magnets of ultra-high strength. Particularly preferred planar magnetic transducers allow for exceptionally large excursion of the diaphragm in a substantially homogenous magnetic field at virtually no distortion, thereby providing heretofore unachieved sound pressure levels. Arrays of such and other transducers are disclosed that provide a full-range speaker with acoustic plane source characteristics.

摘要： Lithium polymer battery are charged from any point of discharge using methods and devices in which the lithium polymer battery is operated during the charge operation as a variable current sink. Most preferably, charging above a threshold voltage is performed such that the charge current is based on a predetermined charge current profile and measured virtual back current resistance.

摘要： Contemplated planar magnetic induction transducers comprise a driver portion that provides a static magnetic field and a dynamic magnetic field to an electrically conductive sound producing membrane to thereby induce a current in the membrane that operates as a voice coil. Most typically, the dynamic magnetic field is produced by a coil that surrounds the magnet, and the membrane is floating above the driver portion. In especially preferred aspects, the sound producing membrane is physically independent from the driver portion and can be separately installed from the driver portion.
