Abstract: A microphone packaging assembly (100) provides a printed circuit board (pcb) (106) for coupling to a microphone device (102) having a bottom acoustic port (104). The pcb provides an acoustic port opening (108) which aligns with the bottom acoustic port (104) of the microphone device (102). A solder pad pattern (110) is disposed on the pcb (106). The solder pad pattern (110) is configured to provide both electrical connection (114) and an incomplete solder seal (116) having purposeful acoustic leak to the microphone device (102). A conformable coating (126) provides a seal to the purposeful acoustic leak. A single acoustic test can be performed to detect proper environmental protection and acoustic sealing of the packaged assembly (100).

Abstract: A radio antenna interface for a portable radio is provided comprising a radio housing having a control top with a circular walled control top opening for receiving an antenna, the circular walled control top opening having an interior surface with a protruding bumper feature formed thereon. An antenna having has a base portion for insertion into the circular walled control top opening, the base portion has a ring feature forming a full circumference bump around the base portion. Once the antenna is assembled with the portable radio, the ring feature is located beneath and abuts with the protruding bumper to form the radio antenna interface. The radio antenna interface provides increased friction to minimize loosening of the antenna under extreme usage conditions.
