1. A sound production device for a display device, the display device comprising a display substrate, the display substrate having an opening area and a non-opening area, the sound production device comprising:
a first electrode layer arranged on the display substrate;
an insulating layer arranged on a side of the first electrode layer away from the display substrate;
an electromagnetic coil arranged on a side of the insulating layer away from the first electrode layer, wherein a vertical projection of the electromagnetic coil on the display substrate falls on the non-opening area, the insulating layer defines a via, and the electromagnetic coil and the first electrode layer are electrically connected through the via; and
a magnetic diaphragm arranged on a side of the electromagnetic coil away from the insulating layer and configured to vibrate and produce sounds in response to a magnetic field generated by the electromagnetic coil, wherein a vertical projection of the magnetic diaphragm on the display substrate falls on the non-opening area.
