Abstract: A method and apparatus for performing noise suppression on an electronic device is provided herein. During operation, a volume-control knob will increase a volume of sound output from a device in a substantially linear fashion (versus knob rotation angle) as a volume-control knob is rotated in a first direction. Noise suppression on the electronic device will also increase as the volume-control knob is rotated in the first direction.

Abstract: A method and apparatus for volume control of an electronic device is provided herein. During operation, a volume-control knob will increase a volume of sound output from a device in a substantially linear fashion (versus knob rotation angle) as a volume-control knob is rotated. Once the volume-control knob is rotated past a predetermined amount, a volume boost is activated, increasing the volume level in a non-linear fashion. More particularly, in one embodiment of the present invention, once the volume-control knob is rotated past the predetermined amount (e.g., 300 degrees), the volume will be increased instantaneously (e.g., by 25%).

Abstract: An improved keypad and speaker assembly is provided. The assembly (100) comprises a speaker grille formed of torturous porting (220), and a keyboard (108) comprising audio slots (120) which are offset beneath the tortuous porting (220). The speaker (104) is aligned beneath the keyboard (108). The tortuous porting (220) and audio slots (120) provide an unobstructed air passage/path between the speaker and ambient while protecting against water intrusion.
