ABSTRACT:
An electroacoustic transducer of the electrodynamic type comprises a flat magnetic system permeable to sound including a diaphragm with conducting tracks which are disposed within the system which has a mass provided with conducting tracks substantially equal to the mass of a diaphragm of equal size intended for capacitive transducers. The construction includes acoustic group delay time elements coupled to the diaphragm and a housing defining a shallow depth air chamber at one side of the diaphragm to give the transducer the form of a sound receiver with a unidirectional characteristic.
