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.

Abstract: Methods and systems for verification of an environmental seal provided by an encapsulant coating of a bottom-ported MEMS microphone package. A purposeful acoustic leak is provided on an upper surface of a package housing (in the form of an additional acoustic port) and a sealing material is applied to an outer surface of the package housing. A properly applied encapsulant coating will completely seal the additional acoustic port on the upper surface of the package housing. However, the placement of the additional acoustic port on the upper surface of the package housing will have a significant, detectable effect on the frequency response of the microphone if it is not completely sealed by the encapsulant coating. Accordingly, the environmental seal provided by the encapsulant coating is verified by confirming, based on the acoustic frequency response testing, that the encapsulant coating has effectively sealed the additional acoustic port on the upper surface of the package housing.

Abstract: A microphone porting structure, comprises a substrate (312) having a bearing surface and a porting through-hole (344) formed therethough for aligning with a microphone port of a bottom ported microphone (334). The bearing surface provides an area against which to seal and the through-hole provides for acoustic path alignment for the audio ports of paired bottom ported microphones mounted to a printed circuit board.

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 translation: 提供改进的键盘和扬声器组件。 组件（100）包括由弯曲端口（220）形成的扬声器格栅和包括在曲折端口（220）下方偏移的音频槽（120）的键盘（108）。 扬声器（104）在键盘（108）下方对准。 曲折的端口（220）和音频槽（120）在扬声器和环境之间提供无阻碍的空气通道/路径，同时防止水侵入。
