Among the electro-mechano-acoustical dynamic transducers there is one whose operating principle is not widely publicized. This transducer is known as Air Motion Transformer (AMT). Using this operation principle, a prototype of an AMT transducer type was designed and built with the particularity of making a cylindrical diaphragm. The behavior of the prototype was assessed and noted that it achieves a 360 degree of quasi uniform high frequency sound pressure level radiation in the horizontal plane. In order to improve the efficiency, several configurations are proposed.
