发明名称 Loudspeaker system and loudspeaker for converting an n-bit digitalized electric signal into an acoustic signal.
摘要 <p>An electrodynamic transducer (1) for use in a loudspeaker system for converting an n-bit digitized electric signal (11) into an acoustic signal comprises n voice-coil devices (4.1, 4.2, ... 4.n) which cooperate with a magnet system (3). The voice-coil devices each comprise a conductor whose length is the same for all the voice-coil devices. The areas of the perpendicular cross-sections of the conductors increase each time by a factor of two starting from the voice-coil device (4.n) corresponding to the least significant bit and going to voice-coil devices corresponding to consecutive more significant bits. In accordance with the invention steps are proposed which enable such a transducer to be constructed in a simple manner if the transducer is a ribbon-type loudspeaker.</p>
