SURFACE MOUNT TYPE ELECTROMAGNETIC SOUNDING BODY AND ITS MOUNTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a surface mount type electromagnetic sounding body that can accurately be positioned with respect to a circuit board by clearly recognizing the outline of the surface mount type electromagnetic sounding body. SOLUTION: The surface mount type electromagnetic sounding body to be mounted on a circuit board has a lower case, an upper case body that constitutes a case body by being combined with the lower case, a diaphragm held inside the case body constituted by the lower case and the upper case, and an actuator to vibrate the diaphragm. The lower case is provided with a projecting part for positioning the lower case to the circuit board when mounting the sounding body.
