[0030] With the improvement of people's living standards and the enhancement of health awareness, electric toothbrushes, as a more efficient and convenient oral cleaning tool, have gradually become popular in daily life. However, traditional electric toothbrushes mainly clean teeth through mechanical vibration. Although they can effectively remove plaque and food debris, they are significantly lacking in improving the user's brushing experience, enhancing the fun of brushing, and educating users on the correct brushing method.

[0031] Traditional electric toothbrushes lack diverse cleaning modes and interactive experiences, making it difficult to meet the personalized needs of different users, especially children who need fun methods to cultivate good brushing habits or adults who are particularly concerned about oral health. Furthermore, the monotonous vibrations produced by traditional electric toothbrushes during cleaning often fail to engage users and may even become tedious with prolonged use, thus affecting their motivation and the effectiveness of brushing.

[0032] Based on this, this application provides an audio electric toothbrush to solve the above-mentioned technical problems. The technical solutions provided by this application will be described in detail below.

[0033] Reference Figure 1This application provides an audio electric motor, including: a housing, a control circuit board 200, a drive controller 300, and a drive motor 400. The housing is provided with a trigger 110. The control circuit board 200 is disposed inside the housing and includes a main control module 210, a switching module 220, a PWM generator 230, a DAC generator 240, and a storage module 250. The main control module 210 is connected to the trigger 110, the switching module 220, the PWM generator 230, the DAC generator 240, and the storage module 250, respectively. The PWM generator 230 and the DAC generator 240 are respectively connected to the switching module 220. The storage module 250 is used to store audio data, the PWM generator 230 is used to generate pulse vibration signals, the DAC generator 240 is used to generate audio vibration signals based on the audio data, and the trigger 110 is used to change the selection state of the switching module 220 for pulse vibration signals or audio vibration signals through the main control module 210. The drive controller 300 is located inside the housing and is connected to the switching module 220. The drive motor 400 is located inside the housing and is connected to the drive controller 300. The drive shaft of the drive motor 400 passes through one end of the housing and is connected to the brush head 800.

[0034] The trigger 110 sends a signal to the main control module 210 to trigger different operating modes, which can be vibration mode, audio playback mode, or a combination of both. According to the instructions of the main control module 210, the output signal source is switched, selecting whether to output a pulse vibration signal generated by the PWM generator 230 or an audio vibration signal generated by the DAC generator 240 based on audio data in the storage module 250. The PWM generator 230 generates a pulse vibration signal to control the drive motor 400 to generate high-frequency vibration, achieving the effect of cleaning teeth. In addition, the DAC generator 240 converts the digital audio data in the storage module 250 into an analog audio signal. This signal can be further converted into an audio vibration signal that the drive motor 400 can recognize. Utilizing bone conduction technology, the audio signal is directly transmitted to the brush head 800 through the vibration of the drive motor, and then transmitted to the user's jawbone and skull through the contact between the brush head 800 and the teeth, ultimately reaching the inner ear for perception. This audio electric toothbrush integrates cleaning and entertainment, meeting diverse user needs. By combining audio playback functionality, the brushing process is no longer monotonous and boring, improving the user experience.

[0035] Reference Figure 3It is understood that the trigger 110 includes a button module 111, which is located on the periphery of the housing and connected to the main control module 210. The button module 111 may include multiple buttons, such as a power button, a mode switch button, a volume up button, a volume down button, and a play / pause button. The power button is used to turn the electric toothbrush on or off. The mode switch button is used to switch between different cleaning modes (such as standard cleaning, intensive cleaning, sensitive mode, whitening mode, etc.) and audio playback modes. Different modes can be switched by single-click, double-click, or long-press. The volume up and volume down buttons are used to adjust the audio playback volume. The play / pause button is used to control audio playback and pause when the audio playback function is activated. Some buttons may be integrated into the same button, meaning one button can trigger different functions through multiple presses or long presses; this application does not limit this.

[0036] Continue to refer to Figure 3 It is understood that the trigger 110 includes a pressure sensor 112, which is disposed within the housing and located beside the drive motor 400, for sensing the pressure on the drive shaft of the drive motor 400. The pressure sensor 112 can monitor the pressure on the drive shaft of the drive motor 400 (i.e., the brush head 800) in real time, thereby ensuring that the force applied by the user while brushing is within a safe range. This helps prevent damage to teeth and gums caused by excessive force, such as enamel abrasion and gum recession. When a user brushes their teeth too hard, causing the pressure on the drive shaft to exceed the preset safety range, the pressure sensor 112 will immediately detect this change and send a signal to the main control module 210. After receiving the signal, the main control module 210 will take corresponding measures, such as reducing the vibration frequency of the electric toothbrush, emitting a gentle prompt sound, or illuminating a warning light, to remind the user to reduce the force. Specifically, the DAC generator 240 is used in the storage module 250 to generate audio vibration signals based on the audio data, such as "Please reduce the force to protect your teeth and gums," to prevent excessive damage to the teeth and gums.

[0037] Continue to refer to Figure 3The trigger 110 includes a timer 113, which is located inside the housing. The timer 113 is used to change the selection state of the switching module 220 for either pulse vibration signal or audio vibration signal according to a preset time, via the main control module 210. The timer 113 ensures that the user brushes their teeth for the recommended time each time, avoiding incomplete cleaning due to insufficient brushing time or unnecessary wear and tear on teeth and gums due to excessive brushing time. Before using the electric toothbrush, the user can preset the brushing time (e.g., set to 2 minutes or default to 2 minutes) via a button or mobile app. The timer 113 starts timing after receiving the preset time. During brushing, the timer 113 monitors the brushing time in real time. When the preset time is reached, the timer 113 sends a signal to the main control module 210. Upon receiving the signal, the main control module 210 switches the current pulse vibration signal to an audio vibration signal via the switching module 220. This signal is transmitted to the brush head 800 through the electric toothbrush's transmission device, and finally, through bone conduction technology, reminds the user that the brushing time is over.

[0038] Understandably, the switching module 220 includes a multiplexer, with its first and second input terminals connected to the output terminals of the PWM generator 230 and DAC generator 240, respectively. The introduction of the multiplexer allows the electric toothbrush to flexibly switch signal sources in different operating modes. For example, in cleaning mode, the electric toothbrush can receive pulse vibration signals through the output terminal of the PWM generator 230 to clean teeth using high-frequency vibrations; while in music playback or reminder mode, it can receive audio vibration signals through the output terminal of the DAC generator 240 to play music or reminder information to the user via bone conduction technology. This ability to flexibly switch signal sources increases the functional versatility of the electric toothbrush and enhances the user experience.

[0039] Reference Figure 2 It is understood that the audio electric toothbrush provided in this application also includes a filter circuit 700, and the switching module 220 is connected to the drive controller 300 through the filter circuit 700. The main function of the filter circuit 700 is to remove high-frequency noise and ripple in the voltage signal, making the voltage signal output to the drive controller 300 purer and more stable. A pure voltage signal helps to reduce the vibration noise and electromagnetic interference generated by the drive motor 400 during operation, and extends the service life of the drive motor 400.

[0040] Continue to refer to Figure 2It is understood that the audio electric toothbrush provided in this application also includes a wireless communication module 500, which is connected to the main control module 210 and used to change the selection state of the switching module 220 for pulse vibration signals or audio vibration signals through the main control module 210. Users can adjust the working mode of the electric toothbrush anytime and anywhere through a mobile APP, such as switching from cleaning mode to music playback mode, or adjusting the vibration intensity and frequency. At the same time, the mobile APP can record data such as the user's brushing habits, brushing time, and brushing force, improving the user experience. In addition, users can select the music played by the audio electric toothbrush through bone conduction through the mobile APP. The wireless communication module 500 includes a Bluetooth module and / or a Wi-Fi module, which are respectively connected to the wireless communication module 500.

[0041] Continue to refer to Figure 2 It is understood that the audio electric toothbrush provided in this application also includes a data interface 610 and a data writing control unit 620. The data interface 610 is located on the outer periphery of the housing and connected to the main control module 210. The main control module 210 is used to receive audio data transmitted from external devices. The data writing control unit 620 is located inside the housing. The input terminal of the data writing control unit 620 is connected to the main control module 210, and the output terminal of the data writing control unit 620 is connected to the storage module 250. The data writing control unit 620 is used to write new audio data into the storage module 250. Users can transmit their favorite music, stories, or other audio content to the electric toothbrush through external devices (such as computers, mobile phones, etc.). This personalized customization allows the electric toothbrush to play the user's favorite audio content while cleaning teeth, increasing the fun and enjoyment of brushing teeth.

[0042] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
