  • Earphone assembly with moisture resistance
    Patent number: 9451349
    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.
    Type: Grant

  • Earphone assembly with moisture resistance
    Patent number: 9078064
    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.

  • Earphone assembly with moisture resistance
    Patent number: 8532323
    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.
