“Touting what the company is calling a ‘windscreen’ design, the concept aims to reduce distracting sounds picked up by the device’s microphone that may make it hard to hear a phone conversation,” Murphy reports. “‘The windscreen is designed to reduce wind noise, air blasts, vocal plosives and other noise,’ Apple said in its patent application. ‘This may enable the speech of a user of the device to remain intelligible despite the presence of such noise during a call, and without requiring the user to shout into the device’s microphone.’”
Murphy reports, “Although the patent was filed on Jan. 11, 2011, the U.S. Patent and Trademark Office approved the application last week. The patent is good for all portable electronic devices that enable users to participate in a real-time two-way conversation.”
