Description

Bone conduction music toothbrush {BONE CONDUCTIVE MUSIC TOOTHBRUSH}

The present invention is intended to help infants and children who do not like brushing teeth, the sound of music from the toothbrush, feel the music vibration with the hand holding the toothbrush, the sound of music through the teeth when the torso of the brush head touches the tooth It is about a bone conduction music toothbrush that is intended to make a novel toothbrush that makes it so funny and fun to brush it so that infants and children can brush their teeth often.

The "toothbrush having a device for providing a variety of sounds" has been invented as already registered in the Patent No. 100743733, the selection of the input unit 10, the power supply unit 90, the display 60, as illustrated in FIG. The control circuit unit 300 includes a main circuit unit 20 and a voice processing unit 30. The control circuit unit 300 includes a main circuit unit 20 including a microprocessor 22 and voice data stored therein. A voice processor 30 having a chip 31, an amplifier 32 for amplifying a voice data signal, and a speaker 70 capable of listening to a voice output, comprising music stored in the voice chip 31 as an amplifier. It provided a "toothbrush with a device that provides a variety of sounds" that amplified and output to a speaker for the toothbrush user to hear.

However, the above-mentioned invention can only feel the music by the ear because the speaker can not feel or hear with your hands or teeth, and the effect may be weak.In addition, in order for the speaker sound to come out of the toothbrush, the speaker inside the toothbrush and the passage outside the toothbrush, that is, the hole It should be, but there are inherent improvement factors such as waterproofing device.

The problem to be solved by the present invention is to add a fun in using a toothbrush, but to listen to music, not just to listen to the ear, but to feel and listen through the hands or teeth to give more fun, wonder or fun The main purpose of the product is to provide a waterproof tooth and a bone conduction music toothbrush that can be heard through the ear and feel music through the hands or teeth and can be heard through the bone conduction.

The present invention has been made in view of the above-mentioned problems, and by using the vibration characteristics and the music output characteristics of the bone conduction speaker, the bone conduction music toothbrush configured to listen to the vibration and the music sound of the toothbrush at the same time, Inside the toothbrush is a battery 100, MP3 or music IC 110, amplifier 120 and a small bone conduction speaker 150, using the built-in battery 100 power, built-in MP3 or music IC ( By amplifying the music output of the 110 to the amplifier 120 to vibrate the bone conduction speaker 150, to vibrate the toothbrush body 300, the bone conduction music is transmitted through the hand or teeth, and the music can be heard by the ear As the bone conduction speaker 150 is sealed inside the toothbrush, the oscillation of the toothbrush body 300 by bone oscillation, the output of music to the outside, the waterproof problem is completely solved, the bone conduction music tooth The bone conduction speaker 150 embedded in the sole has a small size of the yoke and the diaphragm, and the permanent magnet is installed inside the iron piece instead of the outside of the iron piece of the diaphragm by electromagnetic force with the internal magnetic lines of the voice coil. It is characterized by the configuration of the bone conduction music toothbrush by adopting a bone conduction speaker that can improve the vibration characteristics of the bone conduction speaker by making the vibration and to pursue the miniaturization and lightweight of the bone conduction speaker 150.

The present invention by using the vibration characteristics and music output characteristics of the bone conduction speaker (骨傳導) while brushing the toothbrush body music vibration so that you can hear the vibration of the toothbrush and the music sound at the same time to deliver the bone conduction music through the hand or teeth The bone conduction speaker is sealed inside the toothbrush, the bone vibration vibrates the body of the toothbrush itself, and the music output comes out to the outside. The waterproofing problem is completely solved. Children feel the vibrations of the music from the toothbrush and the hand holding the toothbrush, and when the torso of the bristles touches the teeth, the sound of music is heard through the teeth, making brushing a novel and fun way for infants and children to brush their teeth frequently. It is a very useful invention for promoting dental health by doing well.

The battery 100, the MP3 or voice IC 110, the amplifier 120 and the bone conduction speaker 150 are built in the toothbrush body 300, and the music stored in the MP3 or voice IC 110 is built in the amplifier 120. In the amplified and the amplified music output to vibrate the bone conduction speaker 150, and to vibrate the toothbrush body 300 by the vibration of the bone conduction speaker 150,

The bone conduction speaker 150 has a permanent magnet 90 installed at the center lower portion of the iron piece 60 attached to the upper diaphragm 70, and forms an empty space inside the voice coil 40 to form the iron piece 60. The permanent magnet 90 in the lower center constitutes the bone conduction speaker 150 to vibrate in accordance with the voice signal in the voice coil 40 to improve the vibration efficiency,

The yoke 20 is configured to reduce the width in two directions in order to configure the size smaller to form the extension surface 30, 30 ', the diaphragm 70 is also configured to reduce the width in two directions, the diaphragm 70 In order to soften the strength of the zigzag-shaped S-line configuration to make the strength of the diaphragm up and down while maintaining a strong shape from side to side.

In the present invention, as shown in FIG. 1, the toothbrush neck 330 may be separated from the toothbrush body 300, or as the toothbrush neck 330 and the toothbrush body 300 as shown in FIG. have.

As illustrated in FIG. 1, the diaphragm 70 and the iron piece 60 are installed inside the toothbrush body 300 to vibrate the yoke 20 and the voice coil 40 in accordance with a voice signal, thereby displacing the toothbrush body 300. Indirectly vibrating to listen to the ear, the hand feels the music vibration, and when the bristle body 350 is in contact with the tooth to provide a bone conduction music toothbrush that delivers a voice signal to the bone conduction through the tooth.

As described above, the present invention uses the vibration characteristics and the music output characteristics of the bone conduction speaker to brush the toothbrush body and the music by vibrating the toothbrush body so that the toothbrush vibration and the music sound can be heard at the same time. The bone conduction speaker is sealed inside the toothbrush body and the music output comes out by vibrating the toothbrush body with bone vibration, so that the waterproof problem is completely solved. Infant or child dislikes the sound of music from the toothbrush and the vibration of the music with the hand holding the toothbrush, and when the toothbrush body touches the teeth, the sound of music is heard through the teeth, which makes the brushing fun and fun for the infant or child to brush To help you improve your dental health It is characterized.
