Abstract
An audio generating arrangement for an electronic device, the arrangement including at least one loudspeaker, a first body, and a second body at least partially enclosing the loudspeaker. At least one of the first body and the second body is moveable with respect to the other body. An acoustic cavity is formed by the loudspeaker and at least one of the first body and the second body. A volume of the acoustic cavity is configured to increase or decrease in response to movement of the first body or the second body. The arrangement in an electronic device enables increasing the volume of the acoustic cavity without also increasing the outer dimensions of the device.
