A sound transducer (1), comprising at least one acoustically neutral body (2) with which it is possible to associate two sound conveyance elements (9a, 9b) which are shaped approximately like a stylized funnel so as to each form an auricle (10a, 10b), which protrudes outside the acoustically neutral body (2) and is blended with a duct (19a, 19b) with which a three-pole microphone cartridge (25a, 25b) is associated, the cartridge being arranged so that its front end, adapted to acquire the sound, is proximate to the inlet of the duct. The two cold poles (29a, 29b) of the microphone cartridges are mutually inverted, so that the cold pole of one of the microphone cartridges and the hot pole (28a, 28b) and the ground (30a, 30b) of the other of the microphone cartridges are or can be connected to a same connector or socket (31a, 31b) which is or can be associated with a suitable amplifying and/or recording and/or processing device. |
