What are Apple's solid-state buttons?

Apple's solid-state buttons mean that the power and volume buttons can't move up and down, but are fixed on the fuselage, similar to the Home button on the iPhone7/8 mobile phone, and the tapping engine is used to simulate pressing touch.

Guo Ming thinks that this year's two iPhone 15 Pro and iPhone 15 Pro Max (or Ultra) will add two Taptic engine modules to realize solid-state buttons.

A recently exposed patent for Apple's solid-state buttons further reveals the design that Apple may launch. The solid keys of iPhone 15 Pro can not only replace physical keys, but also add special new functions.

The role of apple solid-state buttons

IPhone 15 Pro will be equipped with a "physical button" equivalent to a virtual button, and then the vibration motor of the knocking engine will be used to simulate the feedback of similar physical buttons, which is similar to the virtual Home button used on iPhone 7, but IPhone 15 Pro will have the shape of a button on the frame of the fuselage, which is convenient for the operation of finding the position of the button. According to the news, in order to provide better simulated vibration effect, two Taptic Engine motors will be added on both sides of the fuselage of iPhone 15 Pro.
