Abstract
Improvements in the acoustic motors for dynamic loudspeakers, characterized by the fact that the magnetic flux of the magnet is concentrated in the zone comprising the annular space defined by the magnet and its polar piece envelope in which the moving coil is housed and slid, resulting in the cited concentration of the existence of a frustoconical cavity practiced in the head of the magnet corresponding to the coil mobile and coaxial with it, so as to form in that head ring edges of smaller section in which the concentration of the lines of magnetic force that produce an increase of the effective flow in the air gap, in which the moving coil is displaced.
