[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0046] The terms "first," "second," "third," and the like in the specification and claims of this application and the accompanying drawings are intended to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements, but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0047] Next, please refer to Figure 1, which exemplarily shows a structural diagram of an oral care device provided by an embodiment of the present application. As shown in Figure 1, the oral care device may include: a control unit 110, a motor drive 120 and a motor 130. Among them:

[0048] The control unit 110 may be a microcontroller unit (MCU), also known as a single-chip microcomputer or single-chip microcomputer. This is a chip-level computer that reduces the frequency and specifications of a central processing unit (CPU) and integrates peripheral interfaces such as memory, counters, USB, A / D conversion, UART, PLC, DMA, and even LCD driver circuits on a single chip, thereby providing different control combinations for different applications.

[0049] Specifically, during the oral care process, the control unit 110 of the oral care device can obtain target oral care information, and determine the corresponding target audio drive signal and target cleaning drive signal based on the target oral care information, and output the target audio drive signal and the target cleaning drive signal to the motor 130 in non-overlapping time periods according to preset rules to control the motor 130 to vibrate based on the target audio drive signal and the target cleaning drive signal. By outputting the target audio drive signal and the target cleaning drive signal to the motor 130 in non-overlapping time periods, that is, not outputting the target cleaning drive signal when outputting the target audio drive signal, and not outputting the target audio drive signal when outputting the target cleaning drive signal, the cleaning vibration mode of the motor 130 is ensured to be more stable, and the sound interference generated is less and purer.

[0050] The motor driver 120 may also be a motor driver chip, and the motor 130 may also be, but is not limited to, a sonic motor. The motor driver 120 is configured to drive the motor 130 to vibrate, thereby driving the vibration of the motor 130 to drive a care component connected to the motor 130, such as, but not limited to, a brush head, to play audio via bone conduction, and / or to drive the care component connected to the motor 130 to perform oral care, etc.

[0051] It is understandable that the above-mentioned oral care devices are, for example but not limited to, electric toothbrushes, water flossers, etc., and the oral care devices may also be, but not limited to, equipped with one or more indicator lights, one or more buttons, speakers, etc.

[0052] Next, in conjunction with FIG1 , a control method for an oral care device provided by an exemplary embodiment of the present application is described. Specifically, please refer to FIG2 , which exemplarily illustrates a flow chart of a control method for an oral care device provided by an embodiment of the present application. As shown in FIG2 , the control method for an oral care device may include the following steps:

[0053] S201, obtaining target oral care information.

[0054] Specifically, during the process of oral care, the oral care device can, but is not limited to, obtain at least one target oral care information such as the current target oral care pressure, target oral care amplitude, target oral care position, and target oral care duration of the oral care device through a detection element. It can also, but is not limited to, directly determine at least one target oral care information such as the current target oral care mode and target oral care status of the oral care device. The embodiments of the present application do not limit this.

[0055] S202 : Determine a corresponding target audio driving signal and a target cleaning driving signal based on the target oral care information.

[0056] Specifically, after obtaining the target oral care information, a corresponding target audio file can be obtained based on the target oral care information, and the target audio file can be decoded to obtain a target audio drive signal, and a corresponding target cleaning drive signal can be determined based on the target oral care information. In this embodiment of the present application, the corresponding target audio drive signal and target cleaning drive signal can be directly determined based on the target oral care information, thereby enabling the oral care device to perform corresponding oral care and audio playback according to the target oral care information, thereby ensuring both oral care effectiveness and oral care experience.

[0057] It can be understood that in order to save storage space of the oral care device and reduce the demand for storage space of the oral care device, the oral care device can send the target oral care information to the terminal connected to the oral care device after obtaining the target oral care information, and receive the corresponding target audio file returned by the terminal based on the above-mentioned target oral care information; in order to ensure the audio output efficiency of the oral care device, multiple audio files can be pre-stored in the oral care device, and after the oral care device obtains the target oral care information, it can also directly extract the corresponding target audio file from the multiple pre-stored audio files based on the target oral care information.

[0058] It can be understood that the oral care device can, but is not limited to, pre-store the correspondence between various oral care information and audio drive signals and cleaning drive signals. After obtaining the above-mentioned target oral care information, the target audio drive signal and target cleaning drive signal corresponding to the above-mentioned target oral care information can be directly found from the above-mentioned correspondence.

[0059] S203 , outputting the target audio driving signal and the target cleaning driving signal to the motor in different time periods according to a preset rule, so as to control the motor to vibrate based on the target audio driving signal and the target cleaning driving signal.

[0060] Specifically, the output time period corresponding to the above-mentioned target audio drive signal does not overlap with the output time period corresponding to the above-mentioned target cleaning drive signal, thereby ensuring that the oral care device can output the target cleaning drive signal when outputting the target audio drive signal, and can output the target audio drive signal when outputting the target cleaning drive signal.

[0061] In an embodiment of the present application, after obtaining the target oral care information, the corresponding target audio drive signal and target cleaning drive signal can be determined based on the target oral care information, and the target audio drive signal and the target cleaning drive signal can be output to the motor in non-overlapping time periods according to preset rules to control the motor to vibrate based on the target audio drive signal and the target cleaning drive signal. This does not require the installation of additional speakers, and audio playback can be achieved at a lower cost through bone conduction. The target audio drive signal and the target cleaning drive signal can be output to the motor in non-overlapping time periods, that is, the target cleaning drive signal is not output when the target audio drive signal is output, and the target audio drive signal is not output when the target cleaning drive signal is output. This not only ensures that the target audio drive signal will not affect the drive of the motor's cleaning vibration by the target cleaning drive signal, making the motor's cleaning vibration mode more stable, but also ensures that the target cleaning drive signal will not affect the drive of the motor's audio vibration by the target audio drive signal, making the sound generated by the motor less interfering and purer.

[0062] Optionally, the above-mentioned S203, outputting the target audio drive signal and the target cleaning drive signal to the motor in non-overlapping time periods according to a preset rule, may include: alternately outputting the target audio drive signal and the target cleaning drive signal to the motor, for example, but not limited to, first outputting the target cleaning drive signal to the motor for a first period of time, then pausing the output of the target cleaning drive signal, and outputting the target audio drive signal to the motor for a second period of time, then pausing the output of the target audio drive signal, and then continuing to output the target cleaning drive signal to the motor for the first period of time, and repeating this cycle until the oral care work of the oral care device is completed, and then ending the output of the target cleaning drive signal and the target audio drive signal. In this embodiment of the present application, when alternately outputting the target audio drive signal and the target cleaning drive signal, the target cleaning drive signal can be output first and then the target audio drive signal, so that the user can perform effective oral care operations first, and through the user's effective oral care operations, ensure that the subsequently output target audio drive signal can achieve effective audio playback in a bone conduction manner. At the same time, the embodiment of the present application can also achieve the effect of oral care reminder by alternately outputting the target audio drive signal and the target cleaning drive signal. For example, for the same oral care position (target oral care information), the target cleaning drive signal is continuously output for 30 seconds, and then the target audio drive signal is continuously output for 3 seconds. It is set to remind the user that the oral care time of the oral care position has reached the standard and that the user can switch to the next oral care position for oral care, etc.

[0063] It is understood that the first duration of the alternating output of the target cleaning drive signal can be greater than the second duration of the alternating output of the target audio drive signal, allowing the user to efficiently complete oral care while being able to hear the audio (music or voice). The first duration can be, but is not limited to, 30 seconds, 45 seconds, etc., and the second duration can be, but is not limited to, 3 seconds, 5 seconds, etc.

[0064] It is understandable that the first duration of the alternating output of the target cleaning drive signal may also be equal to the second duration of the alternating output of the target audio drive signal, so that the user can intuitively experience the effect of the regular alternating output of the audio drive signal and the cleaning drive signal. The motor-driven care parts, such as but not limited to the brush head, have a relatively small swing amplitude under the drive of the target audio drive signal. By alternately outputting the target cleaning drive signal and the target audio drive signal at equal times, an oral care method with alternating large and small amplitudes can be formed. Compared with the continuous vibration of the care parts, it has a better effect of loosening dental plaque or tartar. Since the time interval of the target audio drive signal output is short and the time interval of the target cleaning drive signal output is short, the trial experience can form a feeling of listening while caring for the oral cavity.

[0065] It is understandable that when the target audio driving signal and the target cleaning driving signal are alternately output, the target audio driving signal may be output first and then the target cleaning driving signal, which is not limited in this embodiment of the present application.

[0066] It can be understood that the time interval between the target audio drive signal and the target cleaning drive signal output in the non-overlapping time period is less than or equal to the target duration. The target duration can be but is not limited to 0.5s, 0.2s, etc. In this way, the vibration output by the motor of the oral care device can be more continuous, so that the user does not feel the obvious stop vibration experience, especially when the time interval between the cleaning drive signal and the audio drive signal output in the non-overlapping time period is 0, the motor vibration changes more continuously without any sense of jamming, which ensures the oral care efficiency to a certain extent and saves the user a certain amount of oral care time.

[0067] Optionally, the above-mentioned S203, outputting the target audio drive signal and the target cleaning drive signal to the motor in non-overlapping time periods according to a preset rule, may include: when the oral care device outputs the cleaning drive signal to the motor, if the target oral care information satisfies a preset condition, pausing the output of the cleaning drive signal and outputting the target audio drive signal corresponding to the target oral care information to the motor. In this embodiment of the present application, when the target oral care information satisfies the preset condition, the output of the cleaning drive signal may be suspended, and only the corresponding target audio drive signal may be output, thereby prompting the user through the target audio drive signal that the current target oral care information has met the preset condition, so that the user can promptly understand their current oral care status.

[0068] Optionally, the above-mentioned S203, outputting the target audio drive signal and the target cleaning drive signal to the motor in non-overlapping time periods according to preset rules, may include: in the case where the oral care device outputs the audio drive signal to the motor, if the target oral care information does not meet the preset conditions or the audio drive signal has been completely output, then pausing the output of the audio drive signal, and outputting the target cleaning drive signal corresponding to the target oral care information to the motor. In an embodiment of the present application, when the target oral care information does not meet the preset conditions, the output of the audio drive signal may be suspended, and only the corresponding target cleaning drive signal may be output, thereby prompting the user that the current target oral care information does not meet the preset conditions by outputting the target cleaning drive signal, so that the user can promptly understand his current oral care situation. At the same time, when the audio drive signal has been completely output, the output of the audio drive signal will be suspended, and the corresponding target cleaning drive signal will be output so that the user can continue to perform oral care operations.

[0069] Furthermore, when the target oral care information indicates an oral care abnormality or substandard oral care, the target oral care information satisfies a preset condition. Specifically, when the target oral care information indicates an oral care abnormality or substandard oral care, the output of the cleaning drive signal can be suspended, and the corresponding target audio drive signal can be output to notify the user of the current oral care abnormality or substandard oral care, allowing the user to adjust the current oral care operation in a timely manner.

[0070] Optionally, as shown in FIG3 , the target oral care information may include the target oral care pressure currently corresponding to the oral care device, and the preset condition may include that the target oral care pressure is greater than the preset pressure, that is, when the current target oral care pressure of the oral care device is greater than the preset pressure, it can be considered that the current target oral care pressure of the oral care device is too high and there is a risk of damaging the user's oral cavity, then the user can be prompted that the current oral care pressure is too high by outputting a corresponding target audio drive signal, and the user is reminded to reduce the current oral care pressure in time; and / or, the target oral care information may include the target oral care amplitude currently corresponding to the oral care device, and the preset condition may include that the target oral care amplitude is greater than the preset amplitude, that is, when the current target oral care pressure of the oral care device is When the treatment amplitude is greater than the preset amplitude, it can be considered that the current target oral care amplitude of the oral care device is too large, and the user can be prompted that the current oral care amplitude is too large by outputting the corresponding target audio drive signal, and the user is reminded to reduce the current oral care amplitude in time; and / or, the above-mentioned target oral care information may include the current oral care time corresponding to the current oral care position of the oral care device, and the above-mentioned preset conditions may include that the current oral care time is less than the first preset time, and the above-mentioned first preset time can be 30s, 45s, etc., that is, when the current oral care time corresponding to the current oral care position of the oral care device does not meet the standard, the user can be prompted that the current oral care time does not meet the standard by outputting the corresponding target audio drive signal, and the user is reminded that the current oral care position needs to continue oral care.

[0071] Furthermore, when the target oral care information meets the preset conditions, the first target vibration intensity corresponding to the above-mentioned target audio drive signal is smaller than the second target vibration intensity corresponding to the target cleaning drive signal, and / or the first target swing amplitude corresponding to the above-mentioned target audio drive signal is smaller than the second target swing amplitude corresponding to the above-mentioned target cleaning drive signal, and / or the first target duty cycle corresponding to the above-mentioned target audio drive signal is smaller than the second target duty cycle corresponding to the above-mentioned target cleaning drive signal. In this way, while the target audio drive signal can serve as a reminder, the vibration intensity and / or vibration amplitude of the oral care device motor can be reduced, and then the vibration intensity and / or vibration amplitude of the care parts driven by the motor are reduced, so that the oral care device can play the role of overvoltage protection.

[0072] It can be understood that when the target oral care information meets the preset conditions, the output duration corresponding to the above-mentioned target audio drive signal corresponds to or is equal to the duration when the target oral care information is oral care abnormality or oral care does not meet the standards. In this way, the user can promptly understand whether the current oral care is still in an abnormal state or whether the current oral care is still not up to standard by whether the target audio drive signal is output.

[0073] Optionally, as shown in Figure 3, the above-mentioned target oral care information may include the target oral care time currently corresponding to the oral care device, and the above-mentioned preset condition may include the target oral care time reaching a second preset time. The above-mentioned second preset time may be but is not limited to 3 minutes, 2 and a half minutes, etc. In this way, when the target oral care time reaches the second preset time, the output of the cleaning drive signal can be suspended until the user is reminded that the current target oral care time has been met by outputting the corresponding target audio drive signal, and the oral care operation can be ended.

[0074] Furthermore, when the target oral care information meets the preset conditions, the target audio drive amplitude corresponding to the above-mentioned target audio drive signal is reduced, or the target audio drive frequency corresponding to the above-mentioned target audio drive signal is different from the target cleaning drive frequency corresponding to the target cleaning drive signal. Therefore, through the above-mentioned setting, the oral care device can generate a motor audio vibration sound that is significantly different from the sound of the motor cleaning vibration corresponding to the target cleaning drive signal when the target oral care information meets the preset conditions, thereby achieving an obvious reminder effect.

[0075] Furthermore, when the target oral care information meets the preset conditions, the output duration corresponding to the target audio drive signal is a fixed duration. In this way, the user can be reminded that the target oral care information meets the preset conditions by outputting voice or music of a fixed duration; or, the output duration corresponding to the target audio drive signal corresponds to the target oral care area currently corresponding to the oral care device. In this way, the corresponding target audio drive signal is continuously output when caring for the same target oral care area, or the duration of the audio drive signal output corresponding to different oral care areas is different, so as to prompt the user which oral care area is currently being cared for.

[0076] Optionally, as shown in Figure 4, the above-mentioned target oral care information may include the target oral care pressure currently corresponding to the oral care device. When the target oral care pressure is greater than 0, it can be considered that the care part of the oral care device has been placed in the user's mouth, and the prerequisite for playing audio in a bone conduction manner has been met. Only then will the target audio drive signal and the target cleaning drive signal be output to the motor in non-overlapping time periods (i.e., asynchronous output), thereby ensuring the effectiveness of the target audio drive signal driving the motor to play audio and ensuring the effectiveness of the target cleaning drive signal driving the motor to perform oral care.

[0077] Furthermore, as shown in Figure 4, when the target oral care pressure is equal to 0, it can be considered that the care piece of the oral care device is not placed in the user's mouth, and the prerequisite for playing audio by bone conduction is not currently met. In this case, only the target cleaning drive signal can be output to the motor. The cleaning drive signal can be output to remind the user that the oral care device is currently started and the oral care operation can be started. Alternatively, only the cleaning drive signal can be output to remind the user that the oral care device is vibrating or the user has not completed the oral care work and the user still needs to continue oral care. This also avoids the problem that the care piece of the oral care device is not in contact with the user's mouth, resulting in the user being unable to hear the audio by bone conduction after the target audio drive signal is output, resulting in the invalid output of the target audio drive signal. When the target oral care pressure is equal to 0, it can be considered that the care piece of the oral care device is not placed in the user's mouth, and the user does not currently need to perform oral care. In this way, the output of the target cleaning drive signal and the target audio drive signal can be directly suspended to avoid the invalid output of the target cleaning drive signal and the target audio drive signal, reduce the waste of power consumption of the oral care device, and enhance the battery life of the oral care device.

[0078] Optionally, as shown in FIG5 , the oral care device may include a control unit, a motor driver, and a motor. After the control unit determines the corresponding target audio drive signal and target cleaning drive signal based on the acquired target oral care information, it may output the target audio drive signal and the target cleaning drive signal to the motor in non-overlapping time periods based on the same phase or different phases of the motor driver. For example, but not limited to, as shown in FIG5 , the motor driver may, but not limited to, have two different phases, a first phase and a second phase. The above-mentioned target audio drive signal and the target cleaning drive signal may both be input through the first phase or the second phase, or the above-mentioned target audio drive signal may be input through the first phase and the target cleaning drive signal may be input through the second phase, etc. Similarly, the target audio drive signal and the target cleaning drive signal may both be output through the first phase or the second phase of the motor driver, or the above-mentioned target audio drive signal may be output through the first phase of the motor driver and the target cleaning drive signal may be output through the second phase of the motor driver, etc. The embodiment of the present application does not limit this.

[0079] Furthermore, to ensure the playback effect corresponding to the target audio drive signal, when the motor driver outputs the target audio drive signal to the motor, the motor driver amplifies the target amplitude corresponding to the target audio drive signal to a preset multiple, thereby amplifying the loudness of the audio played corresponding to the target audio drive signal. The preset multiple can be, but is not limited to, 2x, 3x, etc.

[0080] In some possible embodiments, as shown in FIG6 , the target oral care information may include a current oral care result of the oral care device, and the current oral care result is configured to represent the current oral care compliance status of the oral care device. After acquiring the target oral care information, when the oral care device stops outputting a cleaning drive signal to the motor, for example, but not limited to, when the cleaning drive signal stops outputting automatically or when the user manually stops outputting the cleaning drive signal, a corresponding target audio drive signal may be output to the motor based on the target oral care information to control the motor to vibrate based on the target audio drive signal, thereby reminding the user which oral care area does not meet the oral care standard or which oral care area needs to be rebrushed after the oral care is automatically or manually ended by the user.

[0081] In some possible embodiments, as shown in FIG7 , the target oral care information may include the current oral care duration corresponding to the current oral care position of the oral care device. After obtaining the target oral care information, when the current oral care duration reaches a first preset duration, it can be considered that the current oral care position has met the care target, and a corresponding first audio drive signal can be output to the motor to prompt the user through the first audio drive signal that the current oral care position has met the care target.

[0082] In some possible embodiments, as shown in FIG8 , the target oral care information may include the current oral care progress corresponding to the oral care device. After acquiring the target oral care information, a corresponding second audio drive signal may be determined based on the current oral care progress, and the second audio drive signal may be output to the motor. The second audio drive signal may be different depending on the range of the current oral care progress. Thus, as the current oral care progress is gradually achieved, for example, but not limited to, as the range of the current oral care progress continues to increase, different oral care achievements may be gradually unlocked. The oral care achievements may be realized through voice reminders or unlocked through different music or sound reminders via the corresponding second audio drive signal, thereby enhancing the oral care interest of users, especially children, and guiding users, especially children, to gradually complete the oral care progress.

[0083] In some possible embodiments, the number of frequencies corresponding to the target cleaning drive signal is less than the number of frequencies corresponding to the target audio drive signal. In this way, the sound emitted by the care parts driven by the drive motor corresponding to the target cleaning drive signal is relatively simple, which can not only ensure the oral cleaning effect corresponding to the target cleaning drive signal, but also ensure that the sound emitted by the care parts driven by the drive motor corresponding to the target audio drive signal is more tonal; and / or, the target cleaning drive amplitude corresponding to the target cleaning drive signal is greater than the target audio drive amplitude corresponding to the target audio drive signal. In this way, by making the swing amplitude of the care parts driven by the drive motor corresponding to the target cleaning drive signal greater than the swing amplitude of the care parts driven by the drive motor corresponding to the target audio drive signal, the problem of noise generation in the care parts when the motor swing is too large is avoided, and the audio output corresponding to the target audio drive signal is purer.

[0084] In some possible embodiments, the oral care device may further include a motor driver. The target audio drive signal and the target cleaning drive signal may be output by the same motor driver. In this way, the motor driver (a type of hardware) may be directly used to drive the motor to generate sound vibration or cleaning vibration without changing the original hardware architecture of the oral care device.

[0085] Furthermore, the oral care device further includes a care piece. The volume corresponding to the sound generated by the motor driven by the target audio drive signal is lower than the target volume, which may be, but is not limited to, 30dB, 35dB, etc., that is, the sound produced externally by the oral care device is very low. The sound generated by the motor is transmitted to the ear of the user currently using the oral care device via bone conduction based on the care piece. In this way, the sound generated by the motor driven by the target audio drive signal can be clearly heard by the user, which can reduce the requirements for the motor's sound and avoid the problem of distortion caused by excessively loud sound directly generated by the motor.

[0086] Optionally, the above-mentioned target cleaning drive signal can be a target cleaning square wave, which can be but is not limited to being generated by the superposition of many sine waves of different frequencies, so its spectrum range will be very wide, and its main energy can be but is not limited to being concentrated at around 300 Hz, thereby ensuring the oral cleaning effect corresponding to the target cleaning drive signal.

[0087] Next, please refer to Figure 9, which exemplifies a flow chart of another method for controlling an oral care device provided by an embodiment of the present application. As shown in Figure 9, the method for controlling an oral care device may include the following steps:

[0088] S901, obtaining target oral care information.

[0089] Specifically, S901 is consistent with S201 and will not be repeated here.

[0090] S902 : Determine a corresponding target audio driving signal and a target cleaning driving signal based on the target oral care information.

[0091] Specifically, S902 is consistent with S202 and will not be repeated here.

[0092] S903 , outputting the target audio driving signal and the target cleaning driving signal to the motor in different time periods according to a preset rule, so as to control the motor to vibrate based on the target audio driving signal and the target cleaning driving signal.

[0093] Specifically, S903 is consistent with S203 and will not be repeated here.

[0094] S904 , when the oral care device outputs a target audio driving signal to the motor, obtain a target audio adjustment instruction.

[0095] Specifically, when the oral care device outputs a target audio drive signal to the motor, the user can also, but is not limited to, adjust the audio output by the oral care device through buttons on the oral care device, that is, the oral care device can obtain the corresponding target audio adjustment instructions.

[0096] It is understandable that the above-mentioned target audio adjustment instruction can also be obtained from, but is not limited to, a terminal connected to the oral care device.

[0097] S905 , in response to the target audio adjustment instruction, controlling the target output frequency corresponding to the target audio driving signal to adjust the pitch of the target audio corresponding to the target audio driving signal.

[0098] Specifically, after the oral care device obtains the target audio adjustment instruction, it can respond to the target audio adjustment instruction and control the target output frequency corresponding to the target audio driving signal to adjust the pitch of the target audio corresponding to the target audio driving signal.

[0099] and / or

[0100] S906 , in response to the target audio adjustment instruction, controlling the continuous output duration corresponding to the target audio driving signal of each target output frequency to adjust the rhythm of the target audio corresponding to the target audio driving signal.

[0101] Specifically, after the oral care device obtains the target audio adjustment instruction, it can respond to the target audio adjustment instruction to control the continuous output duration corresponding to the target audio driving signal of each target output frequency, so as to adjust the rhythm of the target audio corresponding to the target audio driving signal.

[0102] Next, with reference to FIG1 , another control method for an oral care device provided by an exemplary embodiment of the present application will be described, using the control method for an oral care device applied to an electric toothbrush as an example. Specifically, as shown in FIG10 , the control method for an oral care device includes the following steps:

[0103] S1001, obtaining current oral care information of an oral care device.

[0104] Specifically, when a user uses the oral care device for oral care, the oral care device can obtain the corresponding current oral care information through the detection element. The current oral care information may include, but is not limited to, at least one oral care data such as the current oral care position of the oral care device, the current oral care pressure, the current oral care duration, the current movement amplitude, the current oral care progress, the amount of residual dental plaque, the current oral care mode, the current oral care angle, and the current oral care coverage.

[0105] S1002: Determine a corresponding target driving signal based on current oral care information.

[0106] It can be understood that the target driving signal determined is different when the current oral care information corresponding to the oral care device is different, or the current oral care state corresponding to the current oral care information of the oral care device is different.

[0107] S1003, controlling the vibration of the motor based on the target driving signal, so that the motor drives the care part to vibrate and generate sound prompt information, and the sound prompt information matches the current oral care information.

[0108] In an embodiment of the present application, current oral care information of the oral care device is obtained; a corresponding target drive signal is determined based on the current oral care information; and the vibration of the motor is controlled based on the target drive signal, so that the motor drives the care part to vibrate to generate sound prompt information that matches the current oral care information. In this way, the vibration of the motor on the oral care device is used to generate regular sounds that match the current oral care information to output interactive information when using the oral care device, thereby improving the synchronization of information prompts of the oral care device, and there is no need to set up additional speakers, screens and other devices. When the motor vibrates, it drives the care part to vibrate together. When the care part contacts the teeth, the sound is transmitted to the ear in a bone conduction manner, avoiding the problem of setting a speaker hole on the handle of the oral care device, which affects the sealing performance of the handle and increases the manufacturing cost of the oral care device.

[0109] Optionally, the above-mentioned current oral care information may include the current oral care position of the oral care device; the above-mentioned sound prompt information includes at least one of the following: the oral care technique, oral care posture, oral care angle, and oral care amplitude corresponding to the current oral care position; the above-mentioned current oral care position is different, and the above-mentioned sound prompt information is different, so that different sound prompt information is generated by controlling the motor to drive the care parts for different current oral care positions, so as to realize the user's oral care process based on the current oral care position to remind the user to use the corresponding oral care technique, oral care posture, oral care angle, oral care amplitude, etc., so as to assist the user to perform more scientific and effective oral care operations, and improve oral care efficiency and oral care efficiency.

[0110] For example, during the process of the oral care device caring for the current oral care position A or before the oral care currently needs to switch to the oral care position A, the motor can be controlled to drive the care parts to transmit the oral care techniques, oral care posture, oral care angle, oral care amplitude and other sound prompt information corresponding to the oral care position A to the user in a bone conduction manner, thereby assisting the user to better complete the oral care operation for the oral care position A.

[0111] In some possible embodiments, as shown in Figure 11, the above-mentioned S1003, based on the target drive signal, controls the vibration of the motor so that the motor drives the care part to vibrate and generate sound prompt information. The implementation process may include: based on the target drive signal, controls the motor to drive the care part to asynchronously perform cleaning vibration and audio vibration that match the current oral care information, so that the care part performs oral care based on the cleaning vibration and generates sound prompt information based on the audio vibration. In this way, the oral care device can efficiently complete the oral care work by controlling the motor to drive the care part to perform cleaning vibration that matches the current oral care information, and can also control the motor to drive the care part to perform audio vibration that matches the current oral care information to generate corresponding sound prompt information, so that the user can timely understand the corresponding current oral care information and improve the synchronization of the information prompt of the oral care device. It can also avoid the influence of the audio vibration of the care part on its cleaning vibration by controlling the motor to drive the care part to perform cleaning vibration and audio vibration asynchronously, thereby ensuring the oral care effect of the oral care device, and avoid the influence of the cleaning vibration of the care part on the audio vibration, thereby ensuring the fluency and effectiveness of its output sound prompt information.

[0112] Exemplarily, after the oral care device is turned on or woken up, if it receives an oral care instruction with a music mode, that is, it obtains that the current oral care mode corresponding to the oral care device is the music mode (current oral care information), then the motor can be controlled based on the music mode to drive the care part to perform cleaning vibrations matching the music mode. Moreover, after the current oral care time of the user using the music mode of the oral care device for oral care reaches the standard (for example, but not limited to reaching 3 minutes) or the current oral care time corresponding to the current oral care position reaches the standard (for example, but not limited to reaching 30 seconds), the motor can be controlled to stop vibrating to drive the care part to stop the cleaning vibration matching the music mode, and the motor can be controlled to drive the care part to generate corresponding music based on the audio vibration matching the music mode. For example, every time the user meets the standard for an oral care position, the motor will be controlled to drive the care part to perform corresponding audio vibrations to generate corresponding standard music, thereby prompting the user that the current oral care has met the standard or the current oral care position has met the standard, thereby increasing the fun of the user using the oral care device for oral care.

[0113] Furthermore, the current oral care information may include, but is not limited to, at least one of the following oral care information: oral care position, oral care duration, oral care intensity, and oral care amplitude. The cleaning vibration and audio vibration of the care piece change with changes in the same type of oral care information in the current oral care information. For example, but not limited to, as the oral care intensity currently corresponding to the oral care device increases, in order to ensure the oral care effect of the oral care device and the prompt effect of the sound prompt, the duty cycle and / or amplitude corresponding to the cleaning vibration and audio vibration of the care piece will also increase accordingly, thereby ensuring that the cleaning vibration and audio vibration of the care piece can change synchronously with changes in the same type of oral care information in the current oral care information, further improving the synchronization of the oral care device in performing oral care and providing information prompts.

[0114] In some possible embodiments, the target drive signal may be a zone change reminder signal, and the audio prompt information may be zone change reminder information, such as, but not limited to, voice prompt information such as "Please switch to the lower teeth zone," "The current oral care position has met the care standard, please switch to the next oral care position," etc. The output duration of the zone change reminder signal is shorter than the target duration. That is, because the care component of the oral care device will temporarily leave the user's teeth during the process of changing zones (oral care positions), when the audio prompt information is a zone change reminder information, the duration of the reminder vibration of the care component driven by the motor based on the zone change reminder signal is shorter than the target duration (e.g., 3 seconds, 5 seconds, etc.), ensuring that the zone change reminder information can be output within the target duration. This ensures that the zone change reminder information output before the care component leaves the teeth when the user switches oral care positions for oral care can be effectively and completely received by the user, thereby avoiding the problem that the zone change reminder signal is output for too long and the care component has left the user's teeth before the zone change reminder information is completely output, resulting in the subsequent zone change reminder information not being transmitted to the user's ears, resulting in incomplete zone change reminder information received by the user.

[0115] Furthermore, as shown in FIG12 , the above-mentioned current oral care information includes the current oral care duration corresponding to the current oral care position of the oral care device, or the current oral care duration of the oral care device. When the above-mentioned current oral care duration reaches the first preset duration, for example, if the current oral care duration corresponding to the current oral care position (e.g., the upper left tooth area) reaches the first preset duration (e.g., but not limited to, 30 seconds, 45 seconds, etc.), it can be considered that the user's current oral care position has met the care standard, and the target drive signal can be determined to be the above-mentioned zone change reminder signal, and based on the zone change reminder signal, the motor can be controlled to drive the care part to generate the corresponding zone change reminder information, such as, but not limited to, "The upper left tooth area has met the care standard, please switch to the upper middle tooth area" and other voice reminder information, so that after the user's current oral care position meets the care standard, the output voice reminder information can not only remind the user of the oral care position that has been completed, but also remind the user of the next oral care position that should be cared for. Oral care positions are set to guide users to perform oral care in the care order corresponding to each oral care position; if the current oral care time corresponding to the oral care device reaches a first preset time each time (for example, but not limited to 30 seconds, 45 seconds, etc.), it can be considered that the user should currently switch to the next oral care position for oral care, and the motor can be controlled based on the zone change reminder signal to drive the care part to generate corresponding zone change reminder information, such as but not limited to automatically outputting voice reminder information such as "Please switch to the next oral care position" every half minute of care, so that every time the user cares for a certain period of time, the user will be automatically reminded that they should switch the oral care position for care, avoiding the problem of low oral care efficiency caused by users caring at the same oral care position for too long.

[0116] In some possible embodiments, as shown in FIG13 , the current oral care information includes the current oral care pressure and / or current movement amplitude of the oral care device. The current oral care pressure can be detected by, but is not limited to, a pressure detection element, and the current movement amplitude can be detected by, but is not limited to, a motion sensor. The above-mentioned S1003, based on the target drive signal, controls the vibration of the motor so that the motor drives the care piece to vibrate and generate sound prompt information. The process may include: when the current oral care pressure is greater than 0 and / or the current movement amplitude is greater than 0 and less than or equal to the preset amplitude, it can be considered that the care piece is currently in contact with the teeth, and the user is using the oral care device for oral care. Then, the motor vibration can be controlled based on the corresponding target drive signal so that the motor drives the care piece to vibrate and generate corresponding sound prompt information, thereby ensuring that the sound prompt information generated by the motor driving the care piece to vibrate can be transmitted to the user's ears in a bone conduction manner, thereby ensuring the effectiveness of the transmission of the sound prompt information generated by the vibration of the care piece.

[0117] In some possible embodiments, the current oral care information includes the current oral care pressure and / or the current movement amplitude of the oral care device. Since the sound prompt information generated by the vibration of the care piece cannot be effectively obtained by the user after the care piece leaves the user's tooth surface, then, when the current oral care pressure is equal to 0 and / or the current movement amplitude is greater than the preset amplitude, it can be considered that the care piece of the oral care device has currently left the user's tooth surface. For example, the oral care device is currently performing a large-scale zone change care process, then the output of the target sound prompt signal corresponding to the sound prompt information in the target drive signal can be suspended to control the motor to drive the care piece to stop vibrating to generate the sound prompt information, and then stop the output of the sound prompt information, thereby avoiding the problem that the care piece has currently left the user's tooth surface but the care piece still generates invalid vibrations corresponding to the sound prompt information, further improving the effectiveness of the information prompt of the oral care device and enhancing the endurance of the oral care device to a certain extent; or, when the current oral care pressure is equal to 0 and / or the current movement amplitude is greater than the preset amplitude, it can be considered that the care piece of the oral care device has currently left the user's tooth surface, then the output of the target drive signal can be suspended, and the motor can be directly controlled to stop vibrating, thereby avoiding the problem that the motor vibrates to perform invalid oral care and / or invalid information prompts when the care piece is not in contact with the user's tooth surface, thereby enhancing the endurance of the oral care device to a certain extent.

[0118] In some possible embodiments, as shown in FIG14 , the above-mentioned current oral care information includes the current oral care pressure and / or the current movement amplitude of the oral care device. If the current oral care pressure is equal to 0 and / or the current movement amplitude is greater than the preset amplitude, it can be considered that the care piece of the oral care device has currently left the tooth surface of the user, and the corresponding first target drive signal can be determined based on the current oral care information. At this time, if the current oral care information meets the preset conditions for generating sound prompt information, the motor can be controlled based on the first target drive signal to drive the care piece to vibrate and generate sound prompt information; if the current oral care pressure is greater than 0 and / or the current movement amplitude is less than or equal to the preset amplitude, it can be considered that the care piece of the oral care device is currently in contact with the tooth surface of the user, and the corresponding second target drive signal can be determined based on the current oral care information. At this time, if the current oral care information meets the preset conditions, the motor can be controlled based on the above-mentioned second target drive signal to drive the care piece to vibrate and generate sound prompt information. The target drive signal controls the motor to drive the care part to vibrate and generate corresponding sound prompt information; the amplitude of the above-mentioned first target drive signal is greater than the amplitude of the second target drive signal, and / or the frequency of the above-mentioned first target drive signal is greater than the frequency of the above-mentioned second target drive signal, so that when the care part and the user's tooth surface change from a fit (contact) state to a non-fit (non-contact) state and the current oral care information always meets the preset conditions for outputting the sound prompt information, the amplitude and / or frequency of the drive signal can be increased, that is, the first target drive signal with a larger amplitude and / or a larger frequency is used to control the motor to increase the amplitude to increase the loudness of the vibration of the care part, so that the sound prompt information corresponding to the care can be heard even when the care part and the user's tooth surface are not fit (non-contact).

[0119] In some possible embodiments, the above S1003, controlling the vibration of the motor based on the target drive signal so that the motor drives the care parts to vibrate and generate sound prompt information may include: if the current oral care information meets the preset conditions for outputting the sound prompt information, then the motor can be controlled based on the target drive signal to drive the care parts to vibrate and generate corresponding sound prompt information.

[0120] Exemplarily, the above-mentioned current oral care information may also include, but is not limited to, the current total oral care time of the oral care device. When the current total oral care time of the oral care device reaches a preset total time (e.g., 3 minutes, 4 minutes, etc.), it is considered that the current oral care information meets the preset conditions, and the motor can be controlled based on the target drive signal to drive the care piece to vibrate to generate a corresponding current oral care standard-reaching prompt message, prompting the user that the current oral care has reached the standard and there is no need to continue the oral care operation; or, when the current total oral care time of the oral care device does not reach the preset total time (e.g., 3 minutes, 150 seconds, etc.), it is considered that the current oral care information meets the preset conditions, and the motor can be controlled based on the target drive signal to drive the care piece to vibrate to generate a corresponding current oral care standard-unreaching prompt message, prompting the user that the current oral care has not reached the standard and it is necessary to continue the oral care operation.

[0121] For example, the current oral care information may also include, but is not limited to, the current oral care duration corresponding to the current oral care position of the oral care device. When the current oral care duration reaches a second preset duration (e.g., 30 seconds, 45 seconds, etc.), the current oral care information is considered to meet the preset conditions, and the motor may be controlled based on the target drive signal to drive the care piece to vibrate to generate a corresponding current oral care position standard-reaching prompt message or zone change reminder message. The current oral care position standard-reaching prompt message or zone change reminder message may include the next oral care position that the user should switch to, thereby prompting the user that the current oral care position has met the care standard and reminding the user which oral care position the care piece should be attached to after leaving the current oral care position; or, when the current oral care duration does not reach the second preset duration (e.g., 3 minutes, 150 seconds, etc.), the current oral care information is considered to meet the preset conditions, and the motor may be controlled based on the target drive signal to drive the care piece to vibrate to generate a corresponding current oral care position standard-unreaching prompt message, prompting the user that the current oral care position has not yet met the standard and that the care piece needs to continue to be attached to the current oral care position to continue oral care at the current oral care position.

[0122] In some possible embodiments, the current oral care information includes the current oral care pressure of the oral care device. Depending on the current oral care pressure or the pressure range within which the current oral care pressure falls, the motor-driven vibration of the care component generates different sound prompts. These different sound prompts allow the user to accurately understand the current oral care pressure, thereby assisting the user in performing oral care more effectively.

[0123] Optionally, as shown in Figure 15, if the current oral care pressure is less than or equal to the first preset pressure, the corresponding third target drive signal can be determined based on the current oral care information, and the motor can be controlled based on the third target drive signal to drive the care part to vibrate with a first amplitude to generate sound prompt information; if the current oral care pressure is greater than the first preset pressure, the corresponding fourth target drive signal can be determined based on the current oral care information, and the motor can be controlled based on the fourth target drive signal to drive the care part to vibrate with a second amplitude to generate sound prompt information; the amplitude of the above-mentioned third target drive signal is greater than the amplitude of the fourth target drive signal, and the above-mentioned first amplitude is greater than the second amplitude, so that the loudness difference of the sound prompt information generated by the current small oral care pressure is compensated by the larger first amplitude, avoiding the problem that the current oral care pressure is less than or equal to the first preset pressure, that is, the current oral care pressure is too small, resulting in the sound of the prompt information generated by the vibration of the care part being too small, and the user cannot effectively hear it, ensuring that the sound prompt information generated by the vibration of the care part can be clearly heard by the user, thereby improving the effectiveness of the oral care equipment in providing information prompts. The above-mentioned first preset pressure can be, but is not limited to, the pressure exerted on the corresponding care component when the user performs normal oral care, and can be, but is not limited to, set according to actual oral care conditions, etc., and the embodiments of the present application do not limit this.

[0124] Optionally, as shown in Figure 16, if the current oral care pressure is less than or equal to the second preset pressure, the corresponding fifth target drive signal can be determined based on the current oral care information, and the motor can be controlled based on the fifth target drive signal to drive the care piece to vibrate with a third amplitude to generate a sound prompt information. The sound prompt information can be related to the current oral care pressure, or it can be related to other current oral care information other than the current oral care pressure. The embodiment of the present application is not limited to this; if the current oral care pressure is greater than the second preset pressure, it can be considered that the user's current oral care pressure is too high, and the corresponding sixth target drive signal can be determined based on the current oral care information, and the motor can be controlled based on the sixth target drive signal to drive the care piece to vibrate with a fourth amplitude to generate a sound prompt information, such as "The current oral care pressure is too high, please pay attention to adjust ", etc., to prompt the user to adjust the current oral care pressure in time, to avoid the problem that the current oral care pressure of the user is always in an overpressure state and causes damage to the user's gums; the amplitude of the sixth target driving signal is greater than the amplitude of the fifth target driving signal, and the fourth amplitude is greater than the third amplitude. Therefore, when the current oral care pressure is greater than the second preset pressure, that is, when the care part of the oral care device is in an overpressure state, the fourth amplitude is used to compensate for the current excessive oral care pressure, which causes the vibration of the care part to be suppressed and the actual amplitude to be reduced. Therefore, when the current oral care pressure is too high, the actual amplitude of the care part is reduced, resulting in a decrease in the sound of the prompt information. This ensures that the sound prompt information generated by the vibration of the care part can be clearly heard by the user, thereby improving the effectiveness of the information prompt of the oral care device.

[0125] Furthermore, the target driving signal includes a target sound driving signal and a target cleaning driving signal.

[0126] When the current oral care pressure changes from less than or equal to the second preset pressure to greater than the second preset pressure, it can be considered that the care part has currently changed from a non-overpressure state to an overpressure state, and the output amplitude of the target sound drive signal can be increased to control the motor based on the target sound drive signal to increase the amplitude of the audio vibration that drives the care part to generate sound prompt information, thereby avoiding the problem that when the current oral care pressure is too high, the actual amplitude generated by the care part is reduced, resulting in the sound of the prompt information also decreasing, and the output amplitude of the target cleaning drive signal is reduced to control the motor based on the target cleaning drive signal to reduce the amplitude of the cleaning vibration that drives the care part for oral care, thereby reducing the problem of damage to the user's gums caused by excessive oral care pressure.

[0127] It can be understood that the second preset pressure is greater than the first preset pressure.

[0128] Optionally, when the current oral care pressure is within a first preset pressure range, the amplitude of the target drive signal decreases as the current oral care pressure increases. The first preset pressure range can represent a pressure range in which the oral care pressure is too low, such as but not limited to being less than or equal to the first preset pressure, etc., that is, in the first preset pressure range in which the oral care pressure is too low, as the current oral care pressure continues to decrease, the amplitude of the target drive signal can be continuously increased to compensate for the corresponding decrease in the amplitude of the care part, ensuring that the sound prompt information generated by the vibration of the care part can be heard by the user; when the current oral care pressure is within a second preset pressure range, the amplitude of the target drive signal increases as the current oral care pressure increases, and the second preset pressure range can represent a pressure range in which the oral care pressure is too high, such as but not limited to being greater than the second preset pressure, etc., that is, in the second preset pressure range in which the oral care pressure is too high, as the current oral care pressure continues to increase, the amplitude of the target drive signal can be continuously increased to avoid the problem that the actual amplitude generated by the care part continues to decrease as the current oral care pressure continues to increase, resulting in the sound of the prompt information also decreasing; the pressure value within the above-mentioned second preset pressure range is greater than the pressure value within the first preset pressure range.

[0129] In some possible embodiments, the current oral care information may include, but is not limited to, the current oral care position of the oral care device. The current oral care position may be, but is not limited to, detected based on a position detection element of the oral care device (e.g., but not limited to, a multi-axis sensor, a camera, etc.). The sound heard by the user's ear will be different due to different transmission paths of different lengths. In order to avoid the problem of the sound prompt information heard by the user fluctuating when the user cares at different oral care positions, the current oral care position is different or the attributes of the current oral care position (i.e., the transmission distance from the current oral care position to the user's ear) are different. For example, but not limited to, if the upper left tooth area and the upper right tooth area have the same transmission distance from the user's ear, then their corresponding attributes are also the same, while if the upper tooth area and the lower tooth area have different transmission distances from the user's ear, then their corresponding attributes are also different. The amplitude of the target drive signal is different, and the amplitude of the sound prompt vibration generated by the care part driven by the motor controlled by the target drive signal is also different, thereby compensating for the sound differences caused by different oral care positions or different transmission distances, ensuring the uniformity of the prompt sound when the oral care device performs information prompts, and improving the user experience of using the oral care device for oral care.

[0130] Exemplarily, as shown in Figure 17, when the current oral care position is the incisor area, the determined target drive signal is the seventh target drive signal; when the current oral care position is the molar area, the determined target drive signal is the eighth target drive signal; the amplitude of the seventh target drive signal is greater than the amplitude of the eighth target drive signal, and the amplitude of the sound prompt vibration generated by the motor driving the care part based on the seventh target drive signal is greater than the amplitude of the sound prompt vibration generated by the motor driving the care part based on the eighth target drive signal. That is, by making the amplitude of the sound prompt vibration generated by the care part corresponding to the incisor area greater than the amplitude of the sound prompt vibration generated by the care part corresponding to the molar area, the problem that the transmission distance from the incisor area to the user's ear is longer than that of the molar area, resulting in the prompt sound transmitted to the user's ear from the incisor area being smaller than that of the molar area, is compensated, thereby ensuring the uniformity of the sound prompt information heard by the user when the oral care device is in two different oral care positions, namely, the incisor area and the molar area, are cared for, thereby improving the user experience of using the oral care device for oral care.

[0131] Next, please refer to Figure 18, which exemplifies a flow chart of another method for controlling an oral care device provided by an embodiment of the present application. As shown in Figure 18, the method for controlling an oral care device includes the following steps:

[0132] S1801, obtaining current oral care information of the oral care device.

[0133] Specifically, S1801 is consistent with S1001 and will not be repeated here.

[0134] S1802: Determine a corresponding target driving signal based on current oral care information.

[0135] Specifically, S1802 is consistent with S1002 and will not be repeated here.

[0136] S1803, controlling the vibration of the motor based on the target driving signal, so that the motor drives the care part to vibrate and generate sound prompt information, and the sound prompt information matches the current oral care information.

[0137] Specifically, the voice prompt information includes oral care guidance information, including the oral care location where oral care should be performed and / or the next oral care location to be switched to. The oral care guidance information is determined based on a preset oral care path corresponding to multiple oral care locations and the current oral care information. The preset oral care path may, but is not limited to, guiding the user to care for the upper teeth first, then the lower teeth, or guiding the user to care for the left teeth first, then the middle teeth, and finally the right teeth, etc.

[0138] S1804, when the current oral care information of the oral care device does not match the oral care guidance information, controlling the motor vibration based on the target driving signal so that the motor drives the care part to vibrate to generate corresponding target prompt information.

[0139] Specifically, after the motor is controlled based on the target drive signal to drive the care piece to vibrate and generate corresponding oral care guidance information, if the current oral care information of the oral care device does not match the oral care guidance information, for example but not limited to the current oral care position is not the oral care position where oral care should be performed in the oral care guidance information, or the oral care position after the current switch is not the next oral care position to be switched in the oral care guidance information, it can be considered that the user is not currently performing oral care according to the oral care guidance information generated by the care piece. The motor vibration can be controlled based on the target drive signal to drive the care piece to vibrate and generate corresponding target prompt information, such as but not limited to target voice prompt information and / or target vibration prompt information, to remind the user to perform better oral care operations according to the oral care guidance information, so as to avoid the problem of low oral care efficiency caused by the user performing oral care operations aimlessly or arbitrarily.

[0140] It can be understood that the above-mentioned target prompt information can be a voice prompt information generated by the vibration of the nursing part, or it can be a vibration sound prompt corresponding to the nursing part. The embodiment of the present application does not limit this.

[0141] S1805. If the duration of mismatch between the current oral care information of the oral care device and the oral care guidance information reaches a third preset duration, the oral care guidance information corresponding to the oral care device is updated based on the current oral care information of the oral care device, and the motor is controlled to drive the care part to vibrate to generate the updated oral care guidance information.

[0142] Specifically, after controlling the motor to drive the care parts to vibrate based on the target drive signal to generate corresponding oral care guidance information, if the duration of the mismatch between the current oral care information of the oral care device and the oral care guidance information reaches a third preset duration (for example, but not limited to 5 seconds, 10 seconds, etc.), it means that the user currently does not intend to perform oral care according to the original oral care guidance information. Then, the oral care guidance information corresponding to the oral care device can be updated based on the current oral care information of the oral care device, that is, the guidance path of the oral care device can be replanned, and the motor can be controlled to drive the care parts to vibrate to generate updated oral care guidance information, so as to realize the synchronous change of the oral care guidance information according to the actual oral care situation of the user, thereby improving the flexibility and effectiveness of the oral care guidance.

[0143] Referring to FIG. 19 , an embodiment of the present application provides an oral care device 1900 for cleaning a user's oral cavity, particularly the user's teeth. Furthermore, this embodiment can more precisely control the vibration of the motor (i.e., motor 30) within the oral care device 1900 to produce sound, thereby enabling functions such as voice reminders and music playback. This can convert the noise generated by the user during brushing into at least a reminder sound or background music, thereby reducing noise interference during brushing and improving comfort during brushing.

[0144] Referring to FIG. 19 , in some embodiments, an oral care device 1900 includes a handle 10, a battery 20, a motor 30, a circuit board 40, and a brush head 50. The battery 20, motor 30, and circuit board 40 are all disposed within the handle 10. The output shaft of the motor 30 extends outside the handle 10 and is connected to the brush head 50, thereby driving the brush head 50 to vibrate.

[0145] Please refer to Figure 20. The oral care device 1900 includes a processor 41 and a motor drive chip 42 arranged on a circuit board 40. The processor 41, the motor drive chip 42 and the motor 30 are electrically connected in sequence, that is, the processor 41 is electrically connected to the motor drive chip 42, and the motor drive chip 42 is electrically connected to the vibration.

[0146] The processor 41 is used to transmit and receive electrical signals and process them. Exemplarily, the processor 41 may be a microcontroller unit (MCU). A MCU, also known as a single-chip microcomputer or single-chip microcomputer, is a CPU that reduces the frequency and specifications of a central processing unit (CPU) and integrates peripheral interfaces such as memory, timers, USB (Universal Serial Bus), A / D conversion (analog-to-digital conversion), UART (Universal Asynchronous Receiver / Transmitter), PLC (Programmable Logic Controller), DMA (Direct Memory Access, also known as group data transfer, sometimes also called direct memory access), and even LCD (Liquid Crystal Display) driver circuits onto a single chip, forming a chip-level computer that provides different control combinations for different applications. Exemplary processor 41 models include the ESP32-C3.

[0147] In some embodiments, the processor 41 is used to send a drive signal to the motor drive chip 42. The drive signal includes a cleaning signal or an audio signal. Or the drive signal includes both an audio signal and a cleaning signal, and the cleaning signal can be exemplarily a square wave signal. Different square wave signals can have different frequencies or different duty cycles. Different square wave signals can correspond to different brushing modes. For example, the oral care device 1900 includes a gentle mode, a moderate mode, and a strong mode with increasing brushing force. Corresponding to the three brushing modes, the frequencies of the square wave signals can be 200Hz, 250Hz, and 300Hz, respectively, and the amplitudes of the corresponding square wave signals can also increase in sequence to enhance the brushing force through amplitude synchronization.

[0148] In some embodiments, the processor 41 is configured to send an audio signal to the motor driver chip 42. Based on the characteristics of the audio signal, the audio signal can be classified as regular audio signals and irregular audio signals. Regular audio signals exhibit regular variations in frequency and amplitude and carry voice, music, or sound effects. This embodiment uses the example of an audio signal that is regular audio information. Regular audio signals can correspond to voice, music, sound effects, and the like.

[0149] According to relevant technology, the human ear can distinguish sound frequencies between 20Hz and 20kHz. Sound has three characteristics: pitch, loudness, and timbre. Loudness is determined by the amplitude of the sound source's vibration; the greater the amplitude, the louder the sound (i.e., the higher the volume). Pitch is related to the vibration frequency; the higher the frequency, the higher the pitch. Tone is determined by the characteristics of the sound source itself, such as its material and structure. Different timbres result in different waveform characteristics corresponding to the audio signal.

[0150] In this embodiment, when the processor 41 outputs an audio signal, the audio signal includes amplitude information and frequency information. That is, the audio signal has different frequency information or amplitude information in different time periods, thereby causing the motor 30 to generate vibrations of different frequencies or amplitudes, or the audio signal has different frequency information and amplitude information at the same time in different time periods. When the audio signal is input to the motor 30, the frequency information corresponds to the duty cycle of the audio signal, and the amplitude information corresponds to a series of voltage values ​​of the audio signal. Therefore, the audio signal can drive the motor 30 to generate regular vibrations. If the vibration frequency and vibration amplitude of the motor 30 correspond to the frequency information and amplitude information of the voice, music, or sound effect to be played, the motor 30 will generate voice, music, or sound effect of corresponding loudness through the medium, thereby causing the motor 30 to emit sound through the medium.

[0151] It should be noted that the processor 41 can also output a cleaning signal and an audio signal to the motor driver chip 42 at the same time, so that the motor 30 is controlled by the cleaning signal and the audio signal at the same time. While the motor 30 performs cleaning movement (cleaning vibration) according to the cleaning signal, it will also generate regular vibrations according to the audio signal and emit sound through the medium.

[0152] When the drive signal includes only a clean signal, the motor driver chip 42 is used to amplify the clean signal to increase the output power. When the drive signal includes only an audio signal, the motor driver chip 42 is used to amplify the audio signal to increase the output power. When the drive signal includes both a clean signal and an audio signal, the motor driver chip 42 is used to amplify both the clean signal and the audio signal to increase the output power.

[0153] It should be noted that the drive signal needs to be amplified because the amplitude of the drive signal output by the processor 41 is relatively small and the driving ability is weak, which is unable to drive the motor 30 to oscillate. The drive signal is amplified by the motor driver chip 42 to amplify the output power, thereby improving the driving ability of the drive signal, so that the motor 30 can vibrate under the drive of the drive signal. When the drive signal includes a cleaning signal, a cleaning motion is achieved. When the drive signal includes an audio signal, the motor 30 vibrates and emits sound through the medium. Exemplary, the model of the motor driver chip 42 can be UPT8517.

[0154] It's important to emphasize that various circuits or modules can be used to amplify the drive signal. In some embodiments, the motor driver chip 42 can be replaced with an audio amplifier chip to amplify the drive signal. Audio amplifier chips offer the advantages of high fidelity and low distortion, improving the output quality of the amplified audio signal and ultimately enhancing sound quality.

[0155] In comparison, when the driving signal is amplified by the motor driver chip 42, for the same amplification factor and driving capability, the motor driver chip 42 consumes less power and generates less heat than the audio amplifier chip; and after the motor driver chip 42 amplifies the driving signal, although the final sound quality is not as good as that of the audio amplifier chip, the motor driver chip 42 has higher precision control capabilities and can control the motor 30 more accurately. Through tuning, the compatibility between the motor driver chip 42 and the motor 30 can be improved, so that the working state of the motor 30 is better, thereby making the oral care device 1900 have a better cleaning effect.

[0156] Therefore, if the user's requirements for long battery life and better teeth cleaning results for the oral care device 1900 are prioritized, and if the motor 30 is used as the sound source, high fidelity and low distortion parameters are not particularly sensitive, then the sound quality of the resulting sound produced by amplifying the drive signal through the motor driver chip 42 will not differ significantly from that produced by amplifying the drive signal through an audio amplifier chip. A motor driver chip can be used to amplify the drive signal to achieve a longer battery life and better teeth cleaning results for the oral care device 1900 while also ensuring the regular vibration of the motor 30 and the sound produced through the medium. If the priority is to improve the sound quality of the sound produced by the regular vibration of the motor 30 through the medium, an audio amplifier chip can be used to amplify the drive signal.

[0157] In some embodiments, after receiving the amplified cleaning signal, the motor 30 is controlled by the amplified cleaning signal to perform a cleaning motion. During the cleaning motion, the motor 30 drives the brush head 50 to vibrate synchronously via the output shaft. When the brush head 50 comes into contact with the user's mouth, the user's mouth is cleaned, achieving a teeth cleaning effect.

[0158] In some embodiments, after receiving the amplified audio signal, the motor 30 is controlled by the amplified audio signal to generate regular vibrations, which are then transmitted through the medium to produce a sound with a pitch and rhythm. Specifically, because the audio signal is a regular audio signal and includes regular frequency and amplitude information, the frequency information determines the vibration frequency of the motor 30. The duration corresponding to a certain vibration frequency corresponds to the duration of the tone. Different tones can have the same or different durations to form a corresponding rhythm. In other words, the regular frequency information causes the motor 30 to generate regular vibrations, which are transmitted through the medium to produce a sound with a pitch and rhythm.

[0159] Exemplarily, the medium can be air, that is, the motor 30 transmits regular vibrations to the air to form sound waves and transmits them to the human ear, or the motor 30 transmits regular vibrations to the brush head 50 through the output shaft, and the brush head 50 transmits regular vibrations to the air to form sound waves and transmits them to the human ear, or the brush head 50 contacts the user's teeth and transmits regular vibrations to the human ear in the form of bone conduction.

[0160] Specifically, the regular vibration of the motor 30 corresponds to at least one of speech, music, and sound effects. The motor 30 can transmit the regular vibration to the brush head 50 through the output shaft. When the brush head 50 contacts the user's oral cavity (such as teeth or gums), the brush head 50 further transmits the regular vibration to the oral cavity, and the oral cavity further transmits the regular vibration to the user's inner ear, thereby transmitting the sound generated by the motor 30 to the user in the form of bone conduction. Specifically, bone conduction is a sound conduction method that converts sound into mechanical vibrations of different frequencies and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, augument, and auditory center.

[0161] Compared to transmitting sound to the user's ears through a medium such as air, under the condition that the amplification factor of the motor driver chip 42 is the same, the solid sound transmission method such as bone conduction can enable the user to hear louder and clearer sounds. In other words, compared to air transmission, under the premise of being able to hear sounds of the same volume or loudness, the motor driver chip 42 only needs to use a smaller amplification factor to drive the motor 30 to emit a sound of corresponding loudness through bone conduction, thereby reducing the energy consumption of the motor driver chip 42, extending the service life of the oral care device 1900, and improving the endurance of the oral care device 1900. In addition, compared to transmitting sound through air, bone conduction eliminates many steps of sound wave transmission, can achieve clear sound restoration in a noisy environment, and the sound waves will not affect others because of spreading in the air. The method of transmitting sound through bone conduction also helps people with hearing impairments hear the sound corresponding to the regular vibration of the motor 30.

[0162] In summary, in this embodiment, a drive signal is sent to the motor driver chip 42 through the processor, and the drive signal includes an audio signal, or includes an audio signal and a cleaning signal. The drive signal is amplified by the motor driver chip 42 to amplify the output power. When the drive signal includes an audio signal, the amplified audio signal drives the motor 30 to produce regular vibrations. The regular vibrations are transmitted through a medium such as air or a brush head 50, and emit sounds with tones and rhythms, thereby achieving voice, music or sound effect output. In the related art, the motor 30 needs to be driven by a single-frequency drive signal and drive the brush head 50 to vibrate in order to achieve a teeth cleaning effect. This embodiment breaks the conventional thinking and directly drives the motor 30 to vibrate regularly through an audio signal. While eliminating the noise caused by the single-frequency drive signal, it achieves voice, music or sound effect output, thereby improving the comfort of the user when brushing his teeth.

[0163] Furthermore, compared to the audio amplifier chip driving the motor 30 to vibrate, the motor driver chip 42 is matched with the motor 30, and the motor driver chip 42 has a higher precision control capability for the motor 30. After adjustment, the motor driver chip 42 and the motor 30 are more compatible. For the motor driver chip 42 and the motor 30 that have been adapted to each other, the working state of the motor 30 will be better. When the motor driver chip 42 drives the motor 30 to vibrate, the motor driver chip 42 generates less heat and has higher power efficiency. Therefore, the oral care device 10 can have a longer battery life.

[0164] Furthermore, compared to transmitting sound to the user's ears through air, this embodiment can transmit sound to the human ear through bone conduction. Under the same power amplification factor of the motor driver chip 42, bone conduction, a solid-body sound transmission method, allows the user to hear louder and clearer sound. In other words, compared to air transmission, under the premise of being able to hear sounds of the same volume or loudness, through bone conduction sound transmission, the motor driver chip 42 only needs to use a smaller amplification factor to drive the motor 30 and the bone conduction medium to produce sounds of corresponding loudness, thereby reducing the energy consumption of the motor driver chip 42, extending the use time of the audio electric toothbrush 1900, and improving its battery life.

[0165] It should be noted that at the same time, the processor 41 may send only one of the cleaning signal or the audio signal to the motor driver chip 42, or the processor 41 may also send both the cleaning signal and the audio signal to the motor driver chip 42 without modulation, so that the motor driver chip 42 drives the motor 30 to vibrate regularly while performing the cleaning movement and to achieve sound through medium conduction.

[0166] Alternatively, before the processor 41 sends the cleaning signal and the audio signal to the motor driver chip 42, the processor 41 modulates the cleaning signal and the audio signal, modulates the cleaning signal and the audio signal into a space vector pulse width modulation signal (Sinusoidal Pulse Width Modulation, SVPWM), and then sends it to the motor driver chip 42, so that the motor driver chip 42 drives the motor 30 to perform a cleaning motion while vibrating regularly and achieving sound through medium conduction. In contrast, in an embodiment where the cleaning signal and the audio signal are sent to the motor driver chip 42 without modulation, the cleaning signal is superimposed on the audio signal, which will cause the audio signal to be distorted, and ultimately the sound emitted by the motor 30 will also be distorted. However, after the cleaning signal and the audio signal are modulated into space vector pulse width modulation signals and then sent to the motor driver chip 42 to drive the motor 30 to vibrate regularly, the problem of audio signal and sound distortion can be effectively avoided. That is, the cleaning signal and the audio signal are modulated into space vector pulse width modulation signals and sent to the motor driver chip 42. Compared with sending the cleaning signal and the audio signal to the motor driver chip 42 without modulation, the sound quality of the oral care device 1900 can ultimately be improved.

[0167] In addition, the cleaning signal and the audio signal are sent to the motor drive chip 42 together without modulation. Since the two signals are independent of each other, the sending timing of the cleaning signal and the audio signal need to be controlled separately, and the control process is relatively complicated. After the cleaning signal and the audio signal are modulated into space vector pulse width modulation signals, the two signals are modulated into one signal. It is only necessary to control the sending timing of the space vector pulse width modulation signal. The control algorithm is relatively simple. Therefore, the control process of the processor 41 outputting the drive signal can be simplified.

[0168] 21-22 , in some embodiments, the oral care device 1900 further includes a storage module 43, which stores an audio file corresponding to the audio signal. The processor 41 can generate the corresponding audio signal based on the audio file in the storage module 43. This embodiment does not limit the format of the audio file. For example, the audio file can be in MP3, WAV, WMA, MP2, Flac, MIDI, RA, APE, AAC, CDA, MOV, or other formats.

[0169] It should be noted that in some embodiments, when only the processor 41 is required to output a clean signal (generally a PWM square wave signal), the clean signal can be generated in real time and sent to the motor driver chip 42. In this case, there is no need to set up the storage module 43 to pre-store the clean signal. However, when the processor 41 is required to output an audio signal, the storage module 43 can be provided.

[0170] On the one hand, the storage module 43 can pre-store audio files. Only when sound is needed, the processor 41 calls the pre-stored audio files in the storage module 43 and generates the corresponding audio signal. This allows the oral care device 1900 to select the sound timing more flexibly. If the storage module 43 is not provided, in order for the oral care device 1900 to sound, the oral care device 1900 must receive the audio file or audio signal from an external terminal in real time. The oral care device 1900 must be able to communicate with the external terminal, which increases the hardware cost and power consumption.

[0171] On the other hand, the storage module 43 can store audio files of various sizes and formats, so that the sound output by the oral care device 1900 is more diversified. For example, the oral care device 1900 can output sound for a longer time and can output a whole song as background music. The user has non-repeated background music to accompany him during the entire brushing process. For example, the storage module 43 stores audio files corresponding to pattern sounds corresponding to different brushing modes, so that under different brushing modes, the oral care device 1900 can output different pattern sounds to facilitate the user to identify the switching process of the brushing mode or identify the current brushing mode.

[0172] As shown in Figure 21, specifically, the storage module 43 can be a storage space 431 on the processor 41, that is, the processor 41 has its own storage space 431. For example, when the model of the processor 41 is ESP32-C3, the processor 41 has a 2M flash memory (Flash memory) with built-in storage space. Flash memory is a non-volatile memory device. Compared to external memory, internal storage is directly connected to the processor 41 and has a fast read and write speed. It is used to store the instructions and data of the currently running program and directly exchange information with the processor 41, thereby speeding up the processing speed.

[0173] Alternatively, as shown in FIG22 , the storage module 43 may be a memory 432 electrically connected to the processor 41. The memory 432 may be an internal memory or an external memory. The size of the memory 432 may be designed according to actual needs, so that the memory 432 can store audio files with higher sound quality, longer playback time, or a variety of different sounds. In comparison, the storage space 431 on the processor 41 is generally small, while the memory 432 can be configured with the required storage space as needed. Therefore, audio files of various sizes and formats can be stored, making the sound output by the oral care device 1900 more diverse and providing the user with more sound output options.

[0174] In some embodiments, the audio files stored in the storage module 43 correspond to reminder sounds emitted by the motor 30. Exemplarily, the reminder sounds include zone change reminder sounds. When the brush head 50 has been cleaning a fixed area for a preset time, such as 5-30 seconds, the motor 30 outputs a zone change reminder sound, such as "Please change brushing area," to remind the user to move the brush head 50 and change brushing areas in a timely manner.

[0175] Exemplarily, the reminder sound includes an overpressure reminder sound. While brushing, the user presses the brush head 50 against or on the teeth. A pressure sensor is provided on the brush head 50 or a structural member connected to the brush head 50 to detect the pressure applied by the brush head 50 on the teeth or gums. If the pressure is greater than a preset level, it indicates that the user is applying too much pressure, potentially damaging the gums or teeth. At this point, the motor 30 outputs an overpressure reminder sound, such as "Please brush gently," to remind the user to reduce their brushing pressure.

[0176] The reminder sound may include an improper operation reminder sound. While brushing with the oral care device 1900, the user may engage in improper operation, such as brushing too many times, brushing at an incorrect angle, or using an incorrect brushing method. These improper operations may damage the gums and teeth. In this case, the motor 30 vibrates regularly and transmits the improper operation reminder sound through the medium to correct the user's improper operation and effectively protect the gums and teeth.

[0177] In some embodiments, the audio file corresponds to a pattern sound emitted by the motor 30 corresponding to the brushing mode, and different brushing modes correspond to different pattern sounds. Exemplarily, according to the foregoing, the brushing modes of the oral care device 1900 may include a gentle mode, a moderate mode, and a strong mode with successively increasing brushing forces. For different brushing modes, the motor 30 may output different pattern sounds, and the pattern sounds may include at least one of voice, music, and sound effects. For example, corresponding to the three brushing modes of the gentle mode, the moderate mode, and the strong mode with successively increasing brushing forces, the motor 30 may output three sound effects with successively increasing tones, so as to remind the user of the brushing mode currently being executed by the oral care device 1900 through different sound effects.

[0178] 22 , in some embodiments, the oral care device 1900 further includes a communication module 60, which is electrically connected to the processor 41 and configured to establish a communication connection with an external terminal. After establishing a communication connection with the external terminal via the communication module 60, an audio file can be sent to the oral care device 1900 by operating the external terminal, or a corresponding control instruction can be sent to the external terminal by operating the oral care device 1900, causing the external terminal to send the audio file to the oral care device 1900. The oral care device 1900 then receives the audio file via the communication module 60. That is, the processor 41 receives the audio file sent by the external terminal via the communication module 60. Subsequently, the processor 41 can generate a corresponding audio file based on the audio file and send a corresponding audio signal to the motor driver chip 42, thereby controlling the motor 30 to vibrate regularly and transmit sound through the medium.

[0179] The communication module 60 can be a wired connection module, such as a Type-C interface, a Type-A interface, etc. It can also be a wireless connection module, such as a Bluetooth communication module, a Wi-Fi communication module, and a Zigbee communication module.

[0180] In some embodiments, after the processor 41 receives an audio file sent by an external terminal through the communication module 60, it can generate an audio signal in real time based on the received audio file, and after the motor driver chip 42 amplifies the audio signal, it drives the motor 30 to make sound in real time.

[0181] In other embodiments, after receiving an audio file from an external terminal via the communication module 60, the processor 41 may first store the audio file and then call the audio file when needed. Specifically, the oral care device 1900 includes the aforementioned storage module 43, which is electrically connected to the processor 41. After receiving an audio file from an external terminal via the communication module 60, the processor 41 stores the audio file in the storage module 43. When an audio signal is subsequently output, the processor 41 calls the audio file from the storage module 43.

[0182] Exemplarily, the audio file received by the processor 41 from the external terminal through the communication module 60 is the file corresponding to the reminder sound. Therefore, the corresponding reminder sound needs to be output only when a zone change reminder, overvoltage reminder or improper operation reminder is required. Therefore, the processor 41 will call the corresponding audio file and finally drive the motor 30 to output the corresponding reminder sound only when the corresponding conditions of the zone change reminder, overvoltage reminder or improper operation reminder are met.

[0183] It is understandable that when there is no need to update the audio files in the storage module 43 or the storage space of the storage module 43 is large enough to store enough audio files, the communication module 60 can be omitted.

[0184] To reduce storage space, common audio file formats such as MP3, WMA, WAV, APE, FLAC, OGG, and AAC are all compressed formats to reduce file size. When audio playback is required, these audio files must first be decoded to obtain the original audio information before the sound can be played.

[0185] Therefore, in some embodiments, please refer to Figure 22, the oral care device 1900 also includes an audio decoding module 70, which is electrically connected to the processor 41 or integrated in the processor 41. The audio decoding module 70 is used to decode the audio file called out by the processor 41 from the storage module 43, or to perform real-time decoding on the audio file received by the processor 41 through the communication module 60 to generate an audio signal (that is, the original audio information).

[0186] For different audio file formats, the audio decoding module 70 has different forms. For example, for audio files in MP3 format, the audio decoding module 70 may have a module of the corresponding MP3 encoding and decoding algorithm; for audio files in WAV format, the audio decoding module 70 may be a DAC (digital-to-analog converter) module or a PWM (pulse width modulation) module that is built into the processor 41 or that is independent of the processor 41. In other embodiments, the audio file may be first decoded by an external terminal to generate an audio signal, and then sent to the oral care device 1900 to drive the motor 30 to vibrate regularly and transmit sound through the medium. In this case, the audio decoding module 70 may be removed.

[0187] In some embodiments, the power amplification factor of the motor driver chip 42 is greater than or equal to 30 and less than or equal to 45. In this way, the motor driver chip 42 can amplify the drive signal by a sufficient multiple so that the drive signal has a sufficiently large amplitude (or output power), thereby being able to drive the motor 30 to vibrate, and can ensure that the motor 30 has a suitable loudness when vibrating regularly and transmitting sound through the medium, and the user will not be unable to hear the sound clearly due to insufficient loudness, nor will the sound be broken due to too loud loudness.

[0188] When the power amplification factor of the motor driver chip 42 is less than 30, the power amplification factor of the motor driver chip 42 is too small, and the amplified driving signal may not be able to drive the motor 30 to oscillate, or the loudness of the driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is not enough, which makes it difficult for the user to hear the sound corresponding to the regular vibration clearly; when the power amplification factor of the motor driver chip 42 is greater than 45, the power amplification factor of the motor driver chip 42 is too large, and the loudness of the sound emitted by the amplified driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is too large, resulting in a sharp increase in the probability of sound distortion, and ultimately making it difficult for the user to hear the sound corresponding to the regular vibration clearly.

[0189] In some embodiments, the voltage amplification factor of the motor driver chip 42 is greater than or equal to 1.2 and less than or equal to 1.8. This allows the motor driver chip 42 to amplify the voltage of the drive signal by a sufficient multiple, so that the drive signal has a sufficiently large amplitude to drive the motor 30 to vibrate. This also ensures that the motor 30 has an appropriate loudness when vibrating regularly and transmitting sound through the medium, without causing the user to be unclear due to insufficient loudness, and without causing the sound to be broken due to excessive loudness.

[0190] When the voltage amplification factor of the motor driver chip 42 is less than 1.2, the voltage amplification factor of the motor driver chip 42 is too small, and the amplified driving signal may not be able to drive the motor 30 to oscillate, or the loudness of the driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is not enough, which makes it difficult for the user to hear the sound corresponding to the regular vibration clearly; when the voltage amplification factor of the motor driver chip 42 is greater than 45, the voltage amplification factor of the motor driver chip 42 is too large, and the loudness of the sound emitted by the amplified driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is too large, resulting in a sharp increase in the probability of sound distortion, and ultimately making it difficult for the user to hear the sound corresponding to the regular vibration clearly.

[0191] In some embodiments, the current amplification factor of the motor driver chip 42 is greater than or equal to 16 and less than or equal to 24. In this way, the motor driver chip 42 can amplify the current of the drive signal by a sufficient multiple, so that the drive signal has a sufficiently large driving capability, thereby driving the motor 30 to vibrate, and ensuring that the motor 30 has an appropriate loudness when vibrating regularly and transmitting sound through the medium, so that the user will not be unable to hear the sound clearly due to insufficient loudness, nor will the sound be broken due to excessive loudness.

[0192] When the current amplification factor of the motor driver chip 42 is less than 16, the current amplification factor of the motor driver chip 42 is too small, and the amplified driving signal may not be able to drive the motor 30 to oscillate, or the loudness of the driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is not enough, which makes it difficult for the user to hear the sound corresponding to the regular vibration clearly; when the current amplification factor of the motor driver chip 42 is greater than 24, the current amplification factor of the motor driver chip 42 is too large, and the loudness of the sound emitted by the amplified driving signal driving the motor 30 to vibrate regularly and transmit the sound through the medium is too large, resulting in a sharp increase in the probability of sound distortion, and ultimately making it difficult for the user to hear the sound corresponding to the regular vibration clearly.

[0193] In some embodiments, the power supply voltage of the motor driver chip 42 is greater than or equal to 2.4V and less than or equal to 6V. Since the power supply voltage of the motor driver chip 42 affects the power magnification, voltage magnification, and current magnification of the motor driver chip 42, the above-mentioned magnification of the motor driver chip 42 can be adjusted by adjusting the power supply voltage. By setting the power supply voltage to be greater than or equal to 2.4V and less than or equal to 6V, the above-mentioned magnification of the motor driver chip 42 can fall within the corresponding range, thereby achieving the above-mentioned effect. Adjusting the above-mentioned magnification by adjusting the power supply voltage simplifies the control process and is low in cost.

[0194] In some embodiments, the motor 30 is controlled by the amplified audio signal to vibrate regularly and transmit the sound through the medium, and the sound transmitted through the air is less than or equal to 20 decibels. In this way, the user who is currently brushing their teeth with the oral care device 1900 can hear the sound output by the oral care device 1900 through bone conduction, but other people cannot hear the sound output by the oral care device 1900 through air transmission. In other words, only the user who is currently using the oral care device 1900 can hear the sound output by the oral care device 1900, which is beneficial to protecting the privacy of the user who is currently using the oral care device 1900 and avoiding noise to others. At the same time, it can also reduce the power consumption of the toothbrush and improve the battery life of the toothbrush.

[0195] 23-24 , in some embodiments, the motor driver chip 42 includes a PWM output circuit 421 and an H-bridge driver circuit 422. The PWM output circuit 421 is electrically connected to the processor 41 and is configured to output a drive signal to the H-bridge driver circuit 422. Specifically, the PWM output circuit 421 is configured to output the drive signal in the form of a PWM signal to control the speed of the motor 30. Different PWM signals have different duty cycles, voltage values, and current values, thereby enabling the H-bridge driver circuit 422 to adjust the speed of the motor 30.

[0196] The H-bridge drive circuit 422 is electrically connected to the motor 30 and the PWM output circuit 421. The H-bridge drive circuit 422 is used to directly control the direction and start and stop of the motor 30. That is, the H circuit is used to control the motor 30 to start and vibrate or stop working. The H circuit is also used to control the motor 30 to vibrate back and forth in two opposite directions according to the frequency information and amplitude information contained in the amplified drive signal, wherein the vibration frequency of the motor 30 corresponds to the frequency information contained in the drive signal, and the vibration amplitude of the motor 30 corresponds to the amplitude information contained in the drive signal.

[0197] Referring to FIG. 23 , in some embodiments, the H-bridge drive circuit 422 and the PWM output circuit 421 are integrated into the processor 41. That is, the motor driver chip 42 is entirely integrated into the processor 41. This allows for a high level of integration between the motor driver chip 42 and the processor 41, and a short creepage distance between the processor 41 and the motor driver chip 42, enabling short-distance transmission of drive signals and reducing external electromagnetic interference.

[0198] Referring to FIG. 24 , in some embodiments, the H-bridge driver circuit 422 is a discrete device. This allows for flexible positioning of the H-bridge driver circuit 422 and flexible wiring between the H-bridge driver circuit 422 and the motor 30. For example, the H-bridge driver circuit 422 can be positioned closer to the motor 30 to facilitate sending the amplified drive signal to the motor 30 over a short distance. Furthermore, the H-bridge driver circuit 422, PWM output circuit 421, and processor 41 all generate heat during operation. The H-bridge driver circuit 422 generates even more heat due to its frequent switching. Therefore, the H-bridge driver circuit 422 can be positioned away from the processor 41 and PWM output circuit 421 to reduce heat transfer between them and facilitate independent heat dissipation of the H-bridge driver circuit 42.

[0199] Furthermore, the PWM output circuit 421 is integrated with the processor 41. This allows for a high degree of integration between the PWM output circuit 421 and the processor 41, and a short creepage distance between the processor 41 and the PWM output circuit 421, enabling short-distance transmission of the drive signal and reducing external electromagnetic interference. Furthermore, the PWM output circuit 421 is electrically connected to the motor 30 via the H-bridge drive circuit 422. Specifically, the PWM output circuit 421 generates and outputs a drive signal in a PWM format, which is then amplified by the H-bridge drive circuit 422, enabling the H-bridge drive circuit 422 to drive the motor 30 to vibrate.

[0200] In some embodiments, the H-bridge driver circuit 422 includes a MOS transistor (MOS is the abbreviation of MOSFET, which stands for Metal-Oxide-Semiconductor Field-Effect Transistor), and amplifies the drive signal through the MOS transistor. This allows the power amplification factor of the drive signal by the H-bridge driver circuit 422 to be more accurately controlled, thereby more accurately controlling the vibration of the motor 30. An audio amplifier chip generally includes an analog front end and a digital signal processor (DSP). The analog front end receives analog audio signals from an input device and amplifies and processes the signals through an operational amplifier, converting the analog audio signals into digital signals. The DSP processes the digital signals through filtering, equalization, reverberation, and equalization. The audio amplifier chip focuses on restoring the original analog audio signal to improve fidelity and reduce distortion, thereby improving the playback sound quality.

[0201] Referring to FIG. 25 , in some embodiments, the audio files stored in the oral care device 1900 are relatively fixed and may not be updated. The oral care device 1900 may not include the communication module 60. In this case, the oral care device 1900 further includes a battery 20, a storage module 43, and a low dropout regulator (LDO) 80. The storage module 43 is electrically connected to the processor 41 and is used to store fixed audio files. For example, the storage module 43 stores audio files corresponding to fixed reminder sounds and fixed pattern sounds. The battery 20 is electrically connected to the motor driver chip 42 (specifically, it may be connected to the H-bridge driver circuit 422 ) so that the battery 20 supplies power to the motor driver chip 42. The LDO 80 is also electrically connected to the battery 20 and the processor 41. The battery 20 can stably supply power to the processor 41 through the LDO 80. The LDO 80 can extend the operating time of the battery 20 and reduce noise. The model of the low dropout linear regulator 80 may be ME6211C33M5G-N.

[0202] Referring to FIG. 26 , in some embodiments, the processor 41 is integrated into a system-on-chip 90. Unlike the aforementioned oral care device 1900, which has a fixed audio file, the system-on-chip 90 also integrates a communication module 60 and an audio decoding module 70. The processor 41 can receive audio files sent from an external terminal via the communication module 60 and decode the audio files sent from the external terminal via the audio decoding module 70 to generate corresponding audio signals.

[0203] It is understood that the processor 41 can control the audio decoding module 70 to decode the audio file received from the external terminal in real time, or it can store the received new audio file in the storage module 43. When the sound needs to be output, the processor 41 calls the audio file in the storage module 43 and controls the audio decoding module 70 to decode the audio file to generate an audio signal. Through this embodiment, the user can update the sounds that the oral care device 1900 can produce as needed, realizing customized sound playback.

[0204] In some embodiments, the cleaning signal is within a first frequency range, for example, the first frequency range is 200Hz-19000Hz, so that the frequency corresponding to the cleaning signal is relatively high, which can drive the motor 30 and the brush head 50 to vibrate at a high frequency, thereby achieving a better teeth cleaning effect. The audio signal is within a second frequency range, for example, the second frequency range is 20Hz-20000Hz, that is, the second frequency range is the frequency range of sounds that can be heard by the human ear. By comparison, it can be seen that the first frequency range falls within the second frequency range, that is, the first frequency range partially overlaps with the second frequency range, so that it is equivalent to selecting the first frequency range within the second frequency range, that is, selecting the frequency range of the cleaning signal within the frequency range of sound. In this way, when the motor 30 is driven by the cleaning signal and the audio signal at the same time, it can ensure that the user can hear the sound while making the motor 30 have a higher vibration frequency, thereby achieving a better teeth cleaning effect.

[0205] Exemplarily, the second frequency range completely overlaps with the first frequency range, and the first frequency range is 200Hz-19000Hz, to ensure a better teeth cleaning effect, that is, the frequency range of the audio signal is 200Hz-19000Hz. In this way, after the cleaning signal and the audio signal are modulated into a space vector pulse width modulation signal, the frequency range of the space vector pulse width modulation signal is also roughly 200Hz-19000Hz. When the motor 30 is driven to move by the space vector pulse width modulation signal, cleaning movement and sound generation can be achieved simultaneously, and since the motor 30 vibrates within the frequency range of 200Hz-19000Hz, it has a better teeth cleaning effect.

[0206] Please refer to Figure 27. In some embodiments, the oral care device 1900 also includes an audio power amplifier chip 11, or the audio power amplifier chip 11 can directly replace the above-mentioned motor driver chip 42. The audio power amplifier chip 11 is electrically connected to the processor 41 and the motor 30. The processor 41 is also used to send a driving signal to the audio power amplifier chip 11. The driving signal may include at least one of a cleaning signal and an audio signal. The audio power amplifier chip 11 includes an operational amplifier, which is used to amplify the driving signal so that the amplified driving signal can drive the motor 30 to vibrate. When the driving signal includes an audio signal, the driving signal can drive the motor 30 to vibrate regularly and transmit sound through the medium. The motor 30 is controlled by the amplified audio signal to output a sound with tone and rhythm.

[0207] For example, when brushing teeth does not need to be performed through the brush head 50, but regular vibration and sound production are required through the motor 30, the audio signal sent by the processor 41 can be amplified by the audio amplifier chip 11 so that the amplified audio signal has higher fidelity and lower distortion, thereby improving the sound quality when the motor 30 vibrates regularly and produces sound through the medium.

[0260] Next, please refer to Figure 29, which is a schematic diagram of the structure of a control device of another oral care device provided in an embodiment of the present application. The above-mentioned oral care device includes a motor and a care component. As shown in Figure 29, the control device 2900 of the oral care device includes:
