Abstract

An acoustic transduction unit, a manufacturing method thereof and an acoustic transducer, and relates to the technical field of electronic devices. A first electrode is arranged on a first substrate, a support layer is arranged on a side, close to the first electrode, of the first substrate, and a conductive diaphragm layer is arranged on a side, away from the first substrate, of the support layer; 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, it allows the conductive diaphragm layer to be configured as both the diaphragm layer and the second electrode, a layer structure of the acoustic transduction unit is simple.
