ABSTRACT:
A pen possible to sound includes a housing, an ink holder, a fit member, a gear set, and an operative member combined together. An elastic strip is provided in an intermediate portion of the housing, and the ink holder is movably located in a lower portion of the housing. An operative member is positioned in and on the outer surface of the housing, having a rack engaging a pinion of a main gear of the gear set. If the operative member is repeatedly pushed down, the elastic strip is snapped by an eccentric gear of the gear set, giving out sounds.
