The invention before us concerns arrangements for loudspeakers built on the principle off a membrane or other kind of medium (fig. 1 arrow 9) connected to a cabinet (fig. 1 arrow 10). The invention intend to substantially reduce the disturbing effect on the sound occurred by the wave transmission directed into the cabinet (fig. 1 arrow 2). The invention shows how this can be done by forming the details inside of the cabinet so they form a level acoustical resistance for the membrane over the frequency range covered by the loudspeaker. The result will be a higher quality of the sound than with an ordinary design and a more natural sound reproduction. |
