Patent attributes
A loudspeaker is provided having a frame, a device for generating a magnetic field in a magnetic circuit exhibiting an air gap, turns of conductive materials for moving in the air gap, a diaphragm rigidly connected to the turns of the conductive materials that moves in a direction of movement with respect to the frame, the diaphragm having an inner face and an outer face. The inner face of the diaphragm is positioned to face the frame, and the loudspeaker also contains ag rid that stiffens the diaphragm and is shaped to allow the grid to be glued to the outer face of the diaphragm. The grid glued on the diaphragm forces the diaphragm to execute the movements of the turns of conductive materials. The diaphragm obeys impulses given by the turns of the conductive materials, reproduces them identically and transmits vibrations to the air without creating parasitic standing waves.
