Abstract
Systems (300) and methods (1100) for providing audio output from a handheld Communication Device (“CD”). The methods comprise: receiving an audio signal at CD; and dividing the audio signal into a first audio signal with a first frequency bandwidth and a second audio signal with a second frequency bandwidth exclusive of and lower than the first frequency bandwidth. Next, a first electroacoustic transducer (402) produces directional sound in response to the first audio signal. A second electroacoustic transducer (404) produces omnidirectional sound in response to the second audio signal. The first electroacoustic transducer is located on a first side (406) of CD which comprises at least one input device (320, 340) of a user interface (330) that has a stacked arrangement with the first electroacoustic transducer. The second electroacoustic transducer is located on a second side (408) opposed from the first side of the communication device.
