摘要： An approach for omnidirectional audio in a communications device has a communications device housing having a front housing including an opening; an earpiece transducer that directs sound waves through the opening; an audio transducer positioned within the communications device housing to direct audio waves in a direction substantially away from a direction in which the sound waves are directed; a cavity having a long axis oriented off axis relative to the direction in which the audio transducer directs audio waves, the cavity being juxtaposed with the audio transducer so as to receive the audio waves directed therefrom; and an omnidirectional audio port located at an end of the cavity, the omnidirectional audio port including an opening through which the audio waves directed from the audio transducer are emitted.
