<p>In an electrical transducer comprising a magnet system (1), a diaphragm (5) and a voice-coil device (3, 4), coupled to a diaphragm, the voice coil (3) being situated in an air gap (2) of the magnet system (1) and the magnet system further being 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 14 respectively) for receiving an electric signal and a second terminal (13 and 16 respectively) which is electrically coupled to said first terminal, each second terminal being electrically coupled to the electrical connection (20 and 21 respectively) of the voice coil (3) via a lead (18 amd 19) respectively (Fig. 1). The leads (18, 19) are provided with spacer means (22) of an electrically non-conductive material, for example a plastics (Fig. 2a).
<??>Preferably, the connection unit (10) further comprises mechanical coupling means (26, 27) which cooperate with the spacer means (22) to establish a mechanical coupling between said means 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. </p> |
