Abstract -- Loudspeakers developed by Kronos Air Technologies use the same physical phenomenon as an electrostatic fluid accelerator (EFA). This ionic wind technology provides virtually inertialess air oscillations by applying a force directly to the air without the use of a membrane and creates high linear displacement. As a result, Kronos EFA loudspeakers deliver accurate sound production across a wide acoustical range.
I. INTRODUCTION A loudspeaker is a device that converts electrical signal to acoustic waves, i.e. sound. There are different types of loudspeaker. The most popular and widely used is a moving coil type. This type itself has many variations such as electrodynamic, permanent magnet, and horn speakers. A coil is ...
