On first read, the patent application (uncovered by AppleInsider) seems to underwhelm. Apple describes a form-fitted case that would contain an opening that aligns with the microphone on the device (in this case, an iPhone).
The opening would contain a thin mesh, foam, or featherlike screen that would reduce the amount of wind noise that makes its way to the device's microphone.
Apple leaves the door open for many variations of its case, stating that it could be made from rubber, silicon, polycarbonate, acrylic, or plastic.
The mesh windscreen would be embedded into the case and extend across the opening that aligns with the microphone and would also help in preventing moisture, dirt, and other particles from interrupting sound transmission.
Now, if this case design looks familiar to you, you will not be alone. There aren't too many cases on the market that truly vary from this form factor, nor is the concept of a windscreen to protect the microphone of a device a new idea.
Before we pick up the pitchforks and torches and march on Apple headquarters, let's consider that Apple's patent may very well be the first to put the windscreen concept inside the form factor of an iPhone case. If that is true, the patent, however ridiculous it may seem at first, would be valid according to current rules.
Are case manufacturers in trouble if Apple starts making more protection solutions for its products? Let me know your thoughts in the comments!
