Abstract

Audio speakers have become an integral part of our life. They are essential components in mobile phones, music players, televisions, laptops and medical devices like hearing aids. Traditional speakers are voice coil based, and hence quite bulky. With advancements in MEMS (Micro-Electro-Mechanical-Systems) technology, though long after MEMS microphones, accelerometers and numerous types of other MEMS sensors and actuators, speakers have joined the race towards miniaturization.
