Abstract
A ceiling tile loudspeaker includes an acoustic enclosure that defines an acoustic cavity. An electro-acoustic transducer is supported by the enclosure such that a first radiating surface of the electro-acoustic transducer radiates acoustic energy into the acoustic cavity and a second radiating surface of the electro-acoustic transducer radiates acoustic energy outward away from the acoustic enclosure. A first baffle is disposed within the acoustic cavity. The loudspeaker also includes a plurality of partitions, which, together with the first baffle, defines a plurality of ports that acoustically couple the acoustic cavity to an exterior of the enclosure. Each of the plurality of ports includes a first open end, a second open end, and a central axis extending therebetween. The ports are arranged such that their central axes lie in a plane that is substantially perpendicular to a motion axis of the electro-acoustic transducer.
