Apple patent FIG.7, confirmed that a new type of headphone socket embedded microphones 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.TradeTang.com. Such as sound, noise reduction, noise cancellation, echo cancellation, sound source localization and beamforming smart antenna to form all through.
