    Abstract: A microphone includes a diaphragm assembly supported by a substrate. The diaphragm assembly includes at least one carrier, a diaphragm, and at least one spring coupling the diaphragm to the at least one carrier such that the diaphragm is spaced from the at least one carrier. An insulator (or separate insulators) between the substrate and the at least one carrier electrically isolates the diaphragm and the substrate.

    Abstract: The invention relates to a micro-speaker with a second suspension made of highly resilient material installed inside of the speaker. The speaker is able to provide high level acoustic output with low distortion rate in a wide frequency range with a very small and slim structure and it may prevent a disconnection of a lead connecting the voice coil and the electrode. The speaker includes a yoke, a permanent magnet, a plate, a vibration plate integrated with a first suspension, a voice coil, a frame and a protector. The speaker further comprises a second suspension made of highly resilient material installed between the plate and the vibration plate, and is characterized in that the voice coil is attached to the lower surface of the second suspension and the vibration plate is attached to the upper surface of the second suspension and the vibration plate is attached to the upper surface of the second suspension and the outer periphery of the second suspension is fixed to the frame.

    Abstract: An acoustic passive radiator that controls “rocking mode” vibration. An acoustic passive radiator includes a diaphragm for radiating acoustic energy. The diaphragm has a perimeter portion and a central portion. The perimeter portion is thicker than the central portion. The passive radiator further includes a passive radiator suspension. The suspension includes a skin element encasing the diaphragm. The skin element comprises a surround for physically coupling the passive radiator to an acoustic enclosure, pneumatically sealing the diaphragm and the enclosure. The surround has a non-uniform width. The passive radiator a non-pneumatically sealing, non-surround, non-spider suspension element. The non-surround suspension element and the surround coact to control the motion of the diaphragm and to support the weight of the diaphragm.

    Abstract: One embodiment of a low-profile transducer includes a at least one fin perpendicularly mounted on a planar diaphragm, with a voice coil mounted onto the fin. The voice coil may reside in a strong uniform magnetic field. The locations at which the diaphragm is connected to a frame may be coplanar with a center of mass of the diaphragm. The three-dimensional structure of diaphragm and fins may be formed using origami techniques.

    Abstract: A dynamic loudspeaker which operates over a wide band of audio frequencies is disclosed. The speaker includes a speaker cone and voice coil structure of very low mass. A configuration of ribs on the cone and dust cap is important to both high and low frequency performance. The rear suspension for the speaker is a bearing on the voice coil structure. The bearing encircles and slides on the magnetic center pole of the speaker. A method of fabricating the low mass coil structure is disclosed, including forming the bearing surface by heat shrinkage of a low friction tape.
