Abstract: The handle part (2) of a toothbrush houses means which emit acoustic signals in the audible range of the human ear. The means are a chip (3), a battery (4), a sound generator (5), a sound amplifier (6) and a switch (7). By incorporating other similar means, the emission of visual signals is produced. The means (3, 4, 5, 6, 7), which are combined to form a module, are suitable for emitting a melody and/or spoken words. The chip (3) is supplemented with a "timer", the cycle of which is set, or can be set, and preferably lasts for two minutes per actuation. The battery (4) has a life of three months when used twice a day for two minutes in each case.
