PURPOSE: To provide pleasurable teeth brushing while listening to sound of melody or the like by providing a musical sound generating circuit in a toothbrush main body or toothbrush holder to generate the melody or sound. CONSTITUTION: A musical sound generating circuit 2 connected to an output of a switch circuit 1 of a means to provide a starting signal to generate musical sound is composed of an active element or integrated circuit to generate musical sound signals for melody or sound by receiving output signals of the switch circuit 1. An external output circuit 3 is composed of an externally outputting circuit of a speaker such as a piezoelectric speaker and a buzzer, and an externally outputting jack or cord to generate sound to the external based on output signals from the musical sound generating circuit 2. By providing starting to generate the musical sound by the switch circuit 2, the output signals of the musical sound generating circuit 2 generate musical sound through the external output circuit 3. In such a simple constitution as to include an electronic circuit for a musical sound generating function, teeth brushing can be performed with pleasure of listening to the melody in brushing teeth. |
