The foregoing are among the objects attained by the invention, which provides in some aspects a loudspeaker adapted for mounting in a lightbulb socket. The loudspeaker has a body that can, for example, be shaped like a lightbulb and that has a concavity that includes a first volumetric region. A wall that is disposed within the body and that at least partially defines that region includes one or more active diaphragms. The diaphragms generate (i) front waves directed from the first volumetric region to at least one of an environment and a second volumetric region, if any, defined within the concavity, and (ii) back waves directed into the volumetric region. A passive radiator that is elastically mounted in the wall passes from the volumetric region at least a portion of back waves generated by one or more of the active diaphragms. |

1. A loudspeaker, comprising,
A. a body having a concavity that includes a first volumetric region, B. a wall that is disposed within the body and that at least partially defines the first volumetric region, C. the wall including one or more active diaphragms that are coupled to one or more active drivers, the one or more active diaphragms generating
front waves directed from the first volumetric region to at least one of an environment and a second volumetric region, if any, defined within the concavity, andback waves directed into the volumetric region, D. a passive radiator elastically mounted in the wall that passes from the volumetric region at least a portion of back waves generated by one or more of the active diaphragms, and E. an adapter coupled to the body for mounting in a lightbulb socket. |
