Abstract: An integrated multi yoke and loudspeaker system incorporating the yoke for providing a path for the magnetic field of each driver, resulting in higher magnetic field strength and thus a higher sound pressure level. The loudspeaker incorporating the yoke takes a smaller loudspeaker enclosure volume and has a wider sound dispersion. The yoke is configured to provide a common partition for all the drivers to which it is connected.

Abstract: A passive radiator has an arcuate contour that follows the contour of the surface where the passive radiator is mounted. The component may be a television set, audio component, high fidelity loudspeaker, home theater loudspeaker, subwoofer, etc. The arcuate contour of the passive radiator may be convex, parabolic, hyperbolic, or a combination thereof. Furthermore, the convex surface may be cylindrical, spherical or another contour depending on surface contour of the enclosure where it is mounted. The passive radiator rim shape may be circular, rounded rectangular, ovular, elliptical or any other suitable shape. A contoured passive radiator of relatively large size can be mounted on a relatively small TV set, for example a contoured passive radiator equivalent to 8? diameter for a small television set of 14?, thus producing a better bass sound. The contoured passive radiator has wider sound directivity, hence reducing the irregularity of the SPL of the bass sound.

Abstract: A natural hair leather diaphragm for a loudspeaker. The acoustic impedance of the natural hair leather diaphragm is lower than several existing loudspeaker diaphragms and closer to the acoustic impedance of air. As a result, there is improved energy transfer from the loudspeaker to yield higher sound pressure level (SPL). The natural hair leather diaphragm is tough which prevents deformation caused by mechanical pressure and is thus not easily torn.
