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.
Abstract:
A rotary control (100, 500, 700) provides improved running-torque through a running-torque stack up assembly (140). The running-torque stack up assembly (140) may be implemented in a modular approach (500, 700) independent of a shaft (130) and switch housing, or may be implemented to incorporate the shaft (100) and switch housing. The running-torque stack up assembly (140) is formed of a spring (114), a stationary disk (112), and a rotating disk (108) having sliding top and bottom surfaces provided through either pads (106, 110) or an overmolded coating (710).
