摘要： A loudspeaker assembly including: a headrest having a front face facing in a forwards direction and a rear face facing in a rearwards direction, wherein the rearwards direction is opposite to the forwards direction, wherein the headrest is for use with a user's head located in front of the front face of the headrest; a bass dipole loudspeaker mounted to the headrest, wherein the bass dipole loudspeaker includes a drive unit and a diaphragm, wherein the diaphragm has a first radiating surface and a second radiating surface, wherein the first radiating surface and the second radiating surface are located on opposite faces of the diaphragm, wherein the drive unit is configured to move the diaphragm at bass frequencies such that the first and second radiating surfaces produce sound at bass frequencies; a bass waveguide configured to guide bass sound produced by the first radiating surface out from the front face of the headrest via at least one forward-facing opening provided by the bass waveguide, wherein the bass dipole loudspeaker is mounted to the headrest such that bass sound produced by the second radiating surface is able to propagate out from the rear face of the headrest. The bass dipole loudspeaker is mounted to the headrest such that the first radiating surface of the diaphragm is, when the diaphragm is at rest, closer to the rear face of the headrest than to the front face of the headrest. The area of the at least one forward-facing opening is larger than the area of the first radiating surface as projected onto a plane perpendicular to a movement axis of the bass dipole loudspeaker.

摘要： An acoustic metamaterial passive impedance matching device for use in matching the acoustic impedance of a loudspeaker is disclosed. The device includes a baffle having an upper end and a lower end, plates stacked concentrically from the upper end to the lower end, slots positioned between the plates, a side channel extending annularly around a circumference of at least one of the plates, and a spoke interconnecting the plates. Each of the plates includes a central region including perforations. Each of the slots is positioned between two adjacent plates. The side channel defines a chamber including a height greater than the height of the plates and an interior volume enclosing a predetermined volume of air. The side channels and the perforated plates generate an acoustic impedance that matches the complex conjugate acoustic impedance of the loudspeaker to deliver maximum acoustic power. The side channels may include open ends, closed ends, or both for providing an inductive or reactive capacitance.

摘要： This disclosure relates to speakers and more specifically to an array speaker for distributing music uniformly across a room. A number of audio drivers can be radially distributed within a speaker housing so that an output of the drivers is distributed evenly throughout the room. In some embodiments, the exit geometry of the audio drivers can be configured to bounce off a surface supporting the array speaker to improve the distribution of music throughout the room. The array speaker can include a number of vibration isolation elements distributed within a housing of the array speaker. The vibration isolation elements can be configured reduce the strength of forces generated by a subwoofer of the array speaker.
