Abstract
A radio (100) includes an improved speaker porting apparatus which minimizes the occurrence of water intrusion. A keypad membrane (106) has an opening (126) through its front and back surfaces and includes tunneled speaker porting (134) formed within the back surface (122) to direct audio into the opening (126). A circuit board (108) fits onto the back surface (122) of the keypad membrane (106), the circuit board (108) includes speaker porting holes (128) divided into first and second halves (130, 132). The first half of the speaker porting holes (130) align with the opening (126) of the keypad membrane (106) while the second half of the speaker porting holes (132) align with the tunneled speaker porting (134) of the keypad membrane (106). A speaker cone (138) covers the first and second halves of the speaker porting holes (130, 132).
