Abstract: A modularized wireless earphone includes an inner module, a power supply unit, a loudspeaker and an outer casing. The inner module is provided with a circuit module and an insulated casing. The circuit module includes a detection juncture used for detecting, an ANT sensor, a receiving microphone and a control switch. The detection juncture, the ANT sensor, the receiving microphone and the control switch are interconnected electrically. The insulated casing is used to enclose the circuit module and expose the detection juncture, the receiving microphone and the control switch outside an insulation body. The power supply unit is interconnected with the circuit module electrically to provide electricity, the loudspeaker is interconnected with the circuit module electrically, and the outer casing is used to enclose the inner module, the power supply unit and the loudspeaker.

Abstract: An acoustic system includes a conduit, a microphone coupled to an end of the conduit, and a rigid moisture resistant barrier coupled to another end of the conduit to prevent moisture from traversing the length of the conduit towards the receiver. The moisture resistant barrier dampens an audio signal traversing the conduit. The moisture resistant barrier has a submersion rating at least equal to a 7 Ingress Protection rating.

Abstract: An acoustic system includes a receiver (or microphone), a tube, or a moisture resistant screen. The receiver is capable of outputting an audio signal, while the microphone receives an audio signal. The tube is in connection with the receiver (or microphone) and the audio signal travels along a length of the tube. The moisture resistant screen is fitted at an end of the tube. The moisture resistant screen prevents moisture from passing along the tube toward the receiver, and causes an amount of damping to the audio signal. The moisture resistant screen is configured to have a submersion rating greater than or equal to 7 IP.

Abstract: An acoustic system includes a receiver or microphone, a tube, a barrier, and an equalization device. The receiver is capable of outputting an audio signal. The tube is in connection with the receiver and the audio signal travels along a length of the tube. The barrier is fitted along the tube and the barrier prevents moisture from passing along the tube toward the receiver. The barrier causes an amount of damping to the audio signal. The equalization device is in connection with the receiver and the equalization device counteracts the damping by the barrier. The barrier is configured to have a submersion rating greater than or equal to 7 IP.

Abstract: A microphone (100) and method of manufacture thereof is disclosed. The microphone (100) includes a housing (108), a diaphragm assembly (120), a spacer (134), a backplate assembly (140), a body assembly (150), and a printed circuit board (164) disposed within the housing (100). The diaphragm assembly (120) and the backplate assembly (140) constitute a variable capacitor responsive to sound pressure level changes coupled through an acoustic port (118). The base capacitance is inversely proportional to the thickness of the spacer (134). The backplate assembly (140) is disk shaped with protrusions and coupled to the body assembly (150) such that an acoustic passage (172) is formed between an outer edge of the backplate assembly (140) and an inner periphery of the hollow body assembly (150). The body assembly (150) comprises conductive mount (158) for electrically coupling the backplate assembly (140) to a first surface (166) of a circuit board (164).
