<p>The gong (1) has a spring blade (1.1) forming a main body of the gong, and intended to act as a vibrating element, so as to produce a sound following an actuation. The spring blade is formed of a wound wire having partially the shape of a circular arc. The spring blade includes an opening (1.2) formed inside the main body, where the opening is a through-opening or a blind opening. The opening is filled partially by addition of a material (1.3) selected from gold, silver, platinum, or metal alloy. An inertia-block is mounted on the spring blade.
