HANDHELD COMMUNICATION DEVICE WITH A MULTI-ELECTROACOUSITC TRANSDUCER CONFIGURATION AND A REDUCED FORM FACTOR

摘要

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.

1. A method for providing audio output from a handheld communication device, comprising:
receiving an audio signal at the handheld communication device; 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; producing, by a first electroacoustic transducer of the handheld communication device, directional sound in response to the first audio signal, the first electroacoustic transducer located on a first side of the handheld communication device which comprises at least one input device of a user interface that has a stacked arrangement with the first electroacoustic transducer; and producing, by a second electroacoustic transducer of the handheld communication device, omnidirectional sound in response to the second audio signal, the second electroacoustic transducer located on a second side opposed from the first side of the handheld communication device.
