Abstract

- The present invention relates to an electroacoustic transducer, comprising at least one element (2) capable of emitting ions when it is brought to a sufficiently high electrical potential, the said element being arranged between two first electrodes (4, 5), which are parallel to one another and connected to a modulator (6), and between which a modulated electric field acting on the said ions is capable of being created. - According to the invention, it comprises at least one second electrode (8, 9) which is brought to an electrical potential such that a flux of ions (10) is created between the said emitter of ions (2) and the said second electrode (8, 9), and which is disposed in the vicinity of the said ion emitting element (2) so that the said modulated electric field acts on the said flux of ions (10). - The invention applies to acoustic enclosures. <IMAGE>
