SOUND, USE OF A SOUND, PERSONAL CARE IMPLEMENT EXHIBITING A SOUND, AND USE OF A CONNECTOR FOR PROVIDING A SOUND

摘要

A personal care implement comprises a head and a handle, the head being repeatedly attachable to and detachable from the handle. The personal care implement exhibits a sound when the head gets attached to or detached from the handle, thereby providing a signal of secure attachment or detachment. The sound is characterized by a tonal component of about 4000 Hz to about 6000 Hz, preferably over a time length of about 0.1 s to about 0.3 s, on a tonality frequency vs. time analysis.
