Abstract

Field of the invention: The invention pertains to the sound reproduction systems. Constitution: A loudspeaker provided with an air feedback mechanism. The loudspeaker (5) is placed into the box (7). At the centre of the front side of the conical membrane (6) of the loudspeaker (5) there is placed an elastic rubber adaptor (bellow) (1) the one side of which is fixed at the conical membrane (6) and the otherside at the end of a portion of the tube (2). At the lateral mouth of the tube (2) there are fixed tubes (3) ending in mouths existing at the front side of the box (7). The whole air feedback arrangement is manufactured in such away to allow air transmission from the interior of the closed box - through tubes - towards the bellow and inversely. Said bellow is respectively contracted and expanded throughout the moving of the conical membrane of the loudspeaker. This process aims at establishing the balance of pressure in the interior of the box each time the conical membrane is moved so that the resistance to the membrane's movement can be reduced; this contributes to the increase of the range of the movement of the conical membrane and, there by, to the performance upgrade. The air feedback allows the reduction of the size of the box (having almost the dimensions of the loudspeaker) and the creation of a good frequency range so that the performance of the loudspeaker is enhanced.
