The second diaphragm joints the first diaphragm together at multiple locations by pillars passing through the accommodating-openings in the first backplate. The first backplate is located between the first diaphragm and the second diaphragm. The second backplate includes at least one vent hole and it is spaced apart from the second diaphragm.
