Abstract:

A reconfigurable loudspeaker enclosure. A loudspeaker enclosure, includes a first section that includes a mounting location for an acoustic driver. The mounting location includes a first section mating surface and first section walls, a second section that includes an exit for an acoustic element from which acoustic energy can be radiated. The second section includes a second section mating surface and second section walls. The first section mating surface and the second section are rotatably coupled so that in a first configuration the first section walls and the second section walls are substantially continuous, and so that in a second configuration, the walls of the two sections are substantially non-continuous or perpendicular or both and so that in both the first configuration and the second configuration the two sections are coupled acoustically.

International Classification:

A47B 81/06

US Classification:

181198, 181199

Abstract:

Systems and methods to remove heat from an acoustic enclosure are provided. An apparatus includes an enclosure and a free convection passage located within the enclosure. The convection passage includes a non-horizontal convection inlet acoustic port having an inlet opening to the ambient environment and a non-horizontal convection outlet acoustic port having an outlet opening to the ambient environment. At least one heat producing element is coupled to an acoustic port of the free convection passage via a low thermal resistance conduction path. Heat produced by the heat producing element initiates a unidirectional free convective airflow in a direction corresponding to a path between the convection inlet acoustic port and the convection outlet acoustic port.

International Classification:

H04R 1/02
F28F 7/00

US Classification:

165185, 381332

Abstract:

Systems and methods to remove heat from an acoustic enclosure are provided. An apparatus for reproducing acoustic signals includes an acoustic enclosure comprising an acoustic volume. A heat producing element is coupled to the acoustic enclosure, and a thermally conductive structure is thermally coupled to the heat producing element. The thermally conductive structure includes a first surface. A first passive radiator includes a first diaphragm. The first diaphragm extends over at least a portion of the first surface and moves in response to pressure variations within the acoustic volume. Movement of the first diaphragm causes air to flow over the first surface, to facilitate heat removal from the thermally conductive structure.

B62J 3/00

Abstract:

A system includes a micro-mobility device that is configured to support a user on a mechanical structure of the micro-mobility device and a directional acoustic radiating device carried by the mechanical structure of the micro-mobility device and comprising a first acoustic driver that is acoustically coupled to a first passive directional device so as to radiate acoustic energy into the first passive directional device. The first passive directional device comprises an opening in a perimeter of the first passive directional device that extends along a length of the first passive directional device and through which acoustic energy is radiated to an environment to provide a direction of maximum radiation of the first passive directional device

International Classification:

H04R 1/38
H04R 1/28
H04R 1/10

Abstract:

A loudspeaker including an acoustic radiator configured to emit front-side acoustic radiation from a front side and rear-side acoustic radiation from a rear side; a housing that directs the front-side acoustic radiation and the rear-side acoustic radiation; and a plurality of sound-emitting vents arranged in the housing. The plurality of sound-emitting vents includes a first sound-emitting vent arranged in a first end of the housing and a second sound-emitting vent in a second end of the housing. A first distance between the first and second sound-emitting vents defines a first effective length of a first loudspeaker dipole. The plurality of sound-emitting vents further includes third and fourth sound-emitting vents arranged in the housing. A second distance between the first sound-emitting vent and the third and fourth sound-emitting vents defines a second effective length of a second loudspeaker dipole. The second effective length is shorter than the first effective length.

Abstract:

An acoustic device includes first and second acoustic cavities which are air tight. A first passive radiator includes a first passive radiator diaphragm that has a rear surface which is exposed to the first acoustic cavity. A second passive radiator includes a first passive radiator diaphragm having a front surface which is exposed to the first acoustic cavity, and a rear surface which is exposed to the second acoustic cavity. A first electro-acoustic transducer is supported on the second passive radiator diaphragm. The first electro-acoustic transducer is arranged such that a first radiating surface of the first electro-acoustic transducer radiates acoustic energy into the first acoustic chamber and a second radiating surface of the first electro-acoustic transducer radiates acoustic energy into the second acoustic chamber.
