Abstract
A comb-shaped unit used in a music box includes a plurality of metallic strips and an integrally formed striker unit. Melodious music may be generated by the relative motion and hence the friction between the small protrusions and the comb-shaped unit as the cylindrical drum rotates. The strips are spaced apart. Each of some of the strips has a striker provided on its end portion. These strikers are in different sizes. The steel strips of the comb-shaped unit have a greater thickness and hence there is no need for the lead members of the strikers and the additional processes in the prior art. Therefore, the low-frequency effect may be reached and the relevant environmental protection regulations of European Union and the US may be met.
