Abstract: An acoustic transducer includes a housing, which may be a circular cylinder or may have a rectangular cross-section. Two permanent magnets that closely fit the inside of the housing are joined by a linkage having a high magnetic permeability to form a piston that is inserted into the housing. Two pole coils surround the housing with each coil adjacent one of the permanent magnets. The coils are arranged to cause the piston to oscillate within the housing and emit sound waves when coupled to an electrical signal. One end of the housing may be closed except for a barometric leak. A third permanent magnet or a spring may provide a restoring force that centers the piston between the coils when the piston is not subjected to other forces. One of the permanent magnets on the piston may include a vent passage.

Abstract: This document describes methods and apparatus for reducing a magnetic field emitted by an earpiece assembly from extending substantially outside a device associated with the earpiece assembly. Where the earpiece assembly is susceptible to ingress of magnetically attractable particles into the earpiece assembly such a reduction can prolong an operational life of the earpiece assembly. By insert molding magnetically permeable materials throughout an enclosure that surrounds and supports a permanent magnet of the earpiece assembly, a portion of a magnetic field emanating from the permanent magnet that extends outside the device can be substantially reduced or redirected so that the magnetic field ceases to draw the magnetically attractable particles into the earpiece assembly.

Abstract: A audio speaker includes two parallel magnetically permeable plates and a diaphragm movably supported parallel to and approximately equidistant from the plates by a surround. A magnet assembly is coupled to the two magnetically permeable plates and passes through an opening in the diaphragm. The magnet assembly includes two magnets that are coupled with two like poles adjacent the diaphragm. A voice coil is coupled around the opening in the diaphragm to move the diaphragm when an electrical current flows in the voice coil. A suspension ring may surround a portion of the magnet assembly with a first end sealed to the diaphragm and an opposing second end sealed to one of the two plates to separate a back volume from a front volume. Some embodiments include several magnetic assemblies passing through the diaphragm with a voice coil and a suspension ring for each magnet assembly.

Abstract: Embodiments of the invention include a micro speaker assembly that has two drivers, each having a separate yoke, set of magnets, voice coil, and acoustic diaphragms. One driver may produce high frequency (HF) sound while the other produces low frequency (LF) sound. The two drivers may be packaged, side-by-side, within the same micro speaker acoustic enclosure. The drivers may have their respective magnet systems physically connected to each other, in order to enhance heat transfer from one to the other. In particular, a thermally conductive portion or bridge may be used to directly join or thermally connect adjacent edges of the yoke portions of the two magnet systems, in order to enhance heat transfer between the first and second micro speaker drivers. Thus, the assembly can handle more power without overheating. Other embodiments are also described and claimed.
