ABSTRACT:
The case has an opening and a wall section with a hole provided on the wall section and the wall section forms an inner space. The case also has a recessed area surrounding the hole. The piezoelectric diaphragm is supported around its periphery on top of the case so that an enclosure, including the hole, is formed within the inner space. An acoustic resistance sheet is bonded on to the wall section with the adhesive that is filled into the recessed area to close off the hole. With this structure, defective damping caused by seeping of the adhesive is prevented.
