電話拿反了也可以聽

我們通常聽到電話響，為了怕漏接來電，會很快的想從包包裏把手機拿出來，但在匆忙間接電話時，往往會把電話拿反了，為了解決這個問題，GOOGLE申請了一個專利，從軟硬體著手，讓使用者不用擔心。
在硬體上，它在手機的上下兩端分別安裝麥克風與聽筒，讓使用者無論將手機以任一方向持握時仍可正常進行通訊操作，由硬體配合內部感應器自行判斷目前手機持握方向，自動將上下麥克風與聽筒功能作切換。
在軟體上，則是利用Android 4.0時已經可支援上下180度垂直翻轉顯示的介面，因此並不會造成使用上的困擾。如此一來，未來的行動電話將可更人性化。

Title : Controlling microphones and speakers of a computing device
Filing Date : 2011.9.30.
Issue Date : 2012.8.14.
Abstract :
Various aspects of this disclosure are directed to determining an orientation of a mobile computing device. The mobile computing device may include a first microphone-speaker
system and a second microphone-speaker system that can each provide microphone and speaker capabilities. The first microphone-speaker system may be enabled to operate as a speaker device. The enabling of the first microphone-speaker system may include allowing the first microphone-speaker system to provide audio output and disallowing the mobile computing device to process audio input received from the first microphone-speaker system. The second microphone-speaker system may be enabled to operate as a microphone. Enabling the second microphone-speaker
system may include allowing the mobile computing device to process audio input received from the second microphone-speaker system and disallowing the second microphone-speaker system to provide audio output. Enabling of the first and second microphone-speaker systems may be responsive to and based on the determined orientation
