Abstract
In the surface-mounted electromagnetic sound generating body in which a thin resin casing incorporating a sound generating unit is formed with a sound release hole, a sound leakage prevention member separate from the casing is provided around the sound release hole. This arrangement reduces the number of processes for assembling the surface-mounted electromagnetic sound generating body in the manufacture of a mobile phone and at the same time minimizes the volume occupied by the surface-mounted electromagnetic sound generating body on a printed circuit board.
