Claim 0:
1. An acoustic transduction unit, comprising a first substrate, a first electrode arranged on the first substrate, a support layer arranged on a side, close to the first electrode, of the first substrate, and a conductive diaphragm layer arranged on a side, away from the first substrate, of the support layer;
wherein a cavity is enclosed by the support layer, overlapping areas exist between orthographic projections of the first electrode, the conductive diaphragm layer and the cavity on the first substrate, and
the conductive diaphragm layer serves as both a diaphragm layer and a second electrode in the acoustic transduction unit;
wherein the first substrate is provided with a second through hole; and
the acoustic transduction unit further comprises a second signal line arranged on a side, away from the first electrode, of the first substrate, and the second signal line is connected with the first electrode through the second through hole.
