Apple is developing a next-generation iPad mini with a novel vibration-based speaker system, according to Bloomberg.
The new acoustic design would allow sound to emit from flat surfaces on the device's chassis rather than through conventional grills.
By removing these openings, Apple aims to create a more water-resistant enclosure similar to the iPhone's protection level.
Current iPad mini models lack any official IP rating, and that means they're vulnerable to moisture damage, but the speaker hole redesign addresses one of the main areas where water typically penetrates a device.
