A loudspeaker includes an electro-acoustic transducer for converting electrical audio signals into sound waves, and a housing that supports the electro-acoustic transducer. The loudspeaker also includes a shutter that is supported by the housing and is displaceable between a first, closed position in which the shutter substantially covers the transducer, and a second, open position in which the transducer is exposed.
