When miniaturizing already small driver and speaker designs, it is not simply a matter of scaling down all component dimensions. This approach often exceeds critical limits, especially when aiming for an extreme micro-speaker shape or integrating special functions within the miniature speaker’s internal design.

The primary challenge lies in the moving parts—particularly the diaphragm, a delicate and crucial component responsible for converting mechanical movements into sound.

This White Paper explores this issue by analyzing three distinct micro drivers/speakers, focusing on their diaphragm designs. It explains how these advanced designs enhance acoustic efficiency and reduce distortion by improving linearity.

Additionally, the paper includes a dedicated section on diaphragm manufacturing, covering the different foil types used in micro drivers/speakers and the processes involved in shaping them.
