Abstract
A surface-mounted electromagnetic sound generating body comprises: a casing of an almost rectangular parallelepiped incorporating a sound generating unit; a sound release hole formed in a vertical wall of the casing; and a sound leakage prevention member attached to the vertical wall formed with the sound release hole; wherein the sound leakage prevention member is almost equal in shape to the surface of the vertical wall formed with the sound release hole and has an opening coaxial with the sound release hole. As a result, the sound leakage prevention member and the casing are combined together as one compact piece, contributing to a reduced size and an improved effect of the sound leakage prevention.
