Abstract
Loudspeaker sounds in a communications handset may be amplified in predetermined frequency ranges through positioning the loudspeaker between ported and unported spaces. In one embodiment, an empty volume of space disposed in front of the loudspeaker is included to shape the frequency response of the loudspeaker. A port connecting this volume of space to the environment may be located at a longitudinal end of the handset. In one embodiment, the port may pass through a space formed by an antenna loop. An additional empty volume of space may be disposed behind the loudspeaker to further shape the frequency response of the loudspeaker.
