An electrical transducer comprising a magnet system (1), a diaphragm (5) and a voice-coil device (3, 4), coupled to the diaphragm. The voice coil (3) is situated in an air gap (2) of the magnet system and the magnet system is coupled to a chassis (7). The chassis is provided with a connection unit (10) having at least two coupling means (11, 14) each comprising a first terminal (12 and 15 respectively) for receiving an electric signal and a second terminal (13 and 16 respectively) electrically coupled to said first terminal. Each second terminal is electrically coupled to an electrical connection (20 and 21, respectively) of the voice coil via a lead (18 and 19 respectively). The leads (18, 19) are provided with a spacer (22) made of an electrically non-conductive material, for example, a plastic material (FIG. 2a). Preferably, the connection unit further comprises mechanical coupling elements (26, 27) which cooperate with the spacer to establish a mechanical coupling therebetween prior to the electrical coupling of the two leads (18, 19) to the two second terminals (13, 16). The mechanical coupling is established by clamping.
