Because handheld devices are small in size and easy to carry, so the need for strict compliance with the restrictions of hardware systems, the hardware must be retained as input. In accordance with established practice in the handheld computer has a button or switch to facilitate user input operations. Hand-held computers to include one or more of the same connection plug to access aids.
If the hand-held computer that contains a microphone, according to the traditional way, the sound inputs are distributed to handheld computers in the shell on, you must use the limited shell panel.

Apple patent FIG.7, confirmed that a new type of headphone socket embedded microphone will be iPhone goal. The design of the future may also be used in other iOS devices (MacBook, etc.). Connector 506 may provide connectivity to external devices such as headphones, microphones or power devices. FIG.8 is a block diagram of electronic processing components 800 may be used for noise reduction. Location of the new design is different from the headphone jack iPhone 4. We picture tied together, can be visually compared.
All kinds of audio enhancement to achieve, you may use two microphones to complete. Such as sound, noise reduction, noise cancellation, echo cancellation, sound source localization and beamforming smart antenna to form all through. Audio beam-forming may be carried out using two microphones to the sound input, can provide a friendly directional input. When the sound source and the iPhone has some distance to use speaker phone or recording device, the iPhone is beneficial. For example, when we use the camera mode, iPhone.
Some characteristics of the patent application has been iPhone4, like a pair of microphone and noise cancellation technology. The first microphone for calls, voice commands and memo. The second microphone for FaceTime (Apple iPhone (quotations parameter evaluation Gallery proofs) 4 free video chat) and make your calls better.
