LOUDSPEAKER SYSTEM AND LOUDSPEAKER FOR USE IN A LOUDSPEAKER SYSTEM FOR CONVERTING AN N-BIT DIGITIZED ELECTRIC SIGNAL INTO AN ACOUSTIC SIGNAL |
摘要 |
<p>"Loudspeaker system and loudspeaker for use in a loudspeaker system for converting an n-bit digitized electric signal into an acoustic signal." A loudspeaker system for converting an n-bit digitized electric signal (11) into an acoustic signal comprises an electrodynamic loudspeaker (1) with n voice-coil sections (4.1, 4.2, ... 4.n) which coooperate with a magnet system (3). The loudspeaker system further comprises means (18.1, 18.2, ..., 18.n) for short-circuiting a voice-coil section if the value of the bit corresponding to the voice-coil section is such that the relevant voicecoil section is not driven.
