AB  - This paper introduces a novel MEMS technology based audio module for in-ear headphone applications. The device has a small form factor with the whole audio module integrated inside the tip of an in-ear headphone. It is a complete audio solution containing a surface mounted MEMS speaker, an integrated audio amplifier with energy recovery, a digital MEMS microphone as well as digital signal processing for equalization and open-loop predistortion. The module can be manufactured in an SMT line enabling fully automated high-volume mass production with low costs and high yield. The mechanical structure and key benefits of a MEMS based speaker module are discussed in detail, along with the fundamentals of the audio amplifier implementation and signal processing.
