Better iPhone 7 Speakers
The iPhone 7 speakers could play a role in helping users rely on headphones less in some situations. Apple upgraded the speaker on the iPhone 6s, pushing out louder, better sounding audio than the iPhone 6, but we want a little more from the iPhone 7.
A new Apple patent highlights a system that would use acoustic chambers in the iPhone 7 design to amplify the sound while still putting a thin speaker in a slim device. We've seen external cases boost the iPhone speaker without power by routing the sound through channels, so this could be what Apple relies on for the iPhone 7 speaker improvements.
