摘要
It is an object to provide an electro-acoustic converter which can be subjected to air leakage test allowing a gas to pass through a waterproof film in such a condition that the waterproof film is attached to the electro-acoustic converter. An electro-acoustic converter is produced, which includes: a casing having a sound hole; and a diaphragm provided in the casing, wherein the sound hole is covered with the waterproof film to form a closed space, and the closed space is in communication with the outside of the casing through a vent for air leakage test.
