Abstract
A portable loudspeaker with an enclosure that defines an acoustic cavity in an interior of the enclosure, at least one passive radiator exposed to the acoustic cavity, and an electro-acoustic transducer arranged to radiate sound pressure into the acoustic cavity to acoustically energize the at least one passive radiator. A user-operable switch is located in the interior of the enclosure, and a compliant button that forms part of the enclosure and overlies and is spaced from the switch. A sound-deadening member is positioned in the space between the button and the switch. The sound-deadening member is arranged to inhibit sound pressure in the acoustic cavity from reaching the button.
