SLIM PROFILE LOUDSPEAKER

摘要

A narrow-profile balanced subwoofer or similar speaker includes a number of drivers placed side by side in the same lateral plane, with a first set of drivers facing one direction and second set of drivers facing the opposite direction. Their orientation is such that the sum of the forces from the first set of drivers is equal and opposite the sum of the forces from the second set of drivers, thus cancelling, and the sum of the moments from all of the drivers about a center or pivot point substantially equals zero. The speaker may include three or more drivers, symmetrically or asymmetrically spaced. The drivers may be of the same or different sizes, and the audio signal amplitudes may be adjusted to help balance the speaker. Each set of drivers may output sound into separate sound ducts, which may output sound from one or more apertures.

主权项

1. A loudspeaker, comprising:
a speaker assembly; and a plurality of drivers at least three in number mounted on said speaker assembly, each driver being associated with a magnet reaction force and with a moment based in part on its position relative to a center of mass of said speaker assembly; wherein said drivers are laterally mutually offset from one another, and arranged such that the forces and moments associated with the drivers mounted on said speaker assembly reduce or cancel vibrations of the speaker.
