• an inner plate mounted in the mounting compartment of the fixture and having a sound hole formed in the center;
• an outer plate mounted in the mounting compartment of the fixture and having a plurality of sound holes formed on its outer circumference;
• and
• a plurality of springs disposed between the inner and outer plates,
• wherein it is characterized in that, in a normal state, the inner plate and the outer plate are separated by the spring to form a sound path, and when high-pressure compressed air or sprayed liquid is introduced, the outer plate is closely pressed against the inner plate, thereby the inner plate blocking the plurality of sound holes to close the sound path.
