Document Type and Number:
Japanese Patent JP7413010
Kind Code:
B2
Abstract:
The present invention provides a toothbrush that can reduce the burden of touch-up brushing on a parent and allow a child to enjoy brushing without disliking the touch-up brushing. This toothbrush comprises: a brush structure that has a piezoelectric element that vibrates due to an arbitrary sound source data signal; and a body that has the brush structure attached to one end side thereof and supplies current to the piezoelectric element. The piezoelectric element is built into a head part of the brush structure, and a brush part of the brush structure comprises a plurality of bristle bundles that are implanted in a plurality of implantation holes in an implantation surface of the head part. When the head part or the brush part contacts biological tissue inside the oral cavity of a user, the vibration of the piezoelectric element that vibrates due to the sound source data signal is transmitted to bone via the biological tissue and perceived by the user as sound.
