The next iPhone might have much improved sound, a patent filed by Apple suggests.

Apple is looking into creating a sound system for the next iPhone that would use the entire phone as an audio chamber, Tech Radar reports.

The phone's interior would be designed to increase the amount of air passing through the speaker system. This would allow the volume's output to increase and the sound quality to improve.

Apple seems to want to keep the phone as thin as possible in order to compete with other thin smartphones on the market today.

"As portable electronic devices get smaller and thinner, there are increased difficulties in providing the same or greater functionality in a smaller area," the patent reads. "The one or more speakers [of this new system] can produce audio sound that can be directed (e.g., by way of one or more acoustic chambers) to one or more audio output openings."

The patent hints that the audio input on the phone could also be improved, meaning the microphone could benefit as much as the speakers from the improved audio chamber technology.

Still, the biggest change that could be coming to the next iPhone is the elimination of the standard 3.5mm headphone jack. Many Apple fans are upset about the possibility of the removal of the jack because it would force them to purchase new headphones, making old pairs obsolete.

The next iPhone will likely be called the iPhone 7, and may be released this fall. Every other year, Apple makes big changes to the iPhone. When the iPhone 5 was updated to the iPhone 6, Apple increased the screen size of the phone for the first time and also created a Plus model.

This year, the iPhone 6 was updated to the iPhone 6s, which came with some minor changes, like 3D Touch and Live Photos.
