Detailed Implementation Methods

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] The terms "first," "second," etc., used in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or modules is not limited to the listed steps or modules, but may optionally include steps or modules not listed, or may optionally include other steps or modules inherent to such processes, methods, products, or apparatus.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Sound originates from mechanical vibration, which is the mechanical wave generated by the vibration of a source in the air. When the frequency of the mechanical wave is within the range of frequencies that the human ear can hear, it is recognized as sound. Pleasant sound melodies require the use of multi-frequency synthesis technology to create ups and downs, rather than playing a single frequency continuously, because playing a single frequency continuously can easily cause resonance, making people feel uncomfortable. The noise generated by the motor vibration of existing electric toothbrushes is a single frequency.

[0027] Please see Figure 1This is a structural diagram of an electric toothbrush sound effect control system according to the first embodiment of this application, which can reduce the discomfort caused by noise when brushing teeth. The system includes: a pressure acquisition module 101, a central processing module 102, and a motor 103; the output end of the pressure acquisition module 101 is connected to the input end of the central processing module 102, and the pressure acquisition module 101 is used to acquire the pressure currently applied to the brush head of the electric toothbrush; the output end of the central processing module 102 is connected to the motor 103, and the central processing module 102 is used to acquire a preset note sequence when the pressure value is within a preset first pressure range, and obtain a first working frequency according to the note frequency of the acquired preset first note sequence, and obtain a first working beat according to the note playback duration of the first note sequence; the first pressure range is less than a second pressure range in which the brush head contacts the teeth when brushing teeth; the working frequency is used to characterize the vibration frequency, and the working beat is used to characterize the vibration duration; the motor 103 vibrates according to the working frequency and the working beat.

[0028] Specifically, the pressure acquisition module 101 acquires the current pressure on the brush head of the electric toothbrush. When the pressure value is within a preset first pressure range, the central processing module 102 acquires a preset first note sequence; it analyzes the preset first note sequence to obtain the note frequency and note playback duration, converts the note frequency into a first working frequency, and converts the note playback duration into a first working beat; it then sends the first working frequency and the first working beat to the motor 103. The motor 103 vibrates according to the first working frequency and the first working beat. The frequency of the noise emitted during vibration is the working frequency, which is within the range of frequencies audible to the human ear, and can be 20Hz to 20kHz. The working frequency can also be a high frequency exceeding 20kHz. By programming the level energy of the high frequency, a frequency audible to the human ear can be obtained. Programming the level energy of the high frequency can remove sound harmonics in the noise, making the audio played by the motor 103 more pleasant to listen to, thereby converting the noise emitted during vibration into a preset audio. The first and second pressure ranges can be set according to actual conditions. For example, when adults use electric toothbrushes, the second pressure range can be 50gf to 400gf. When minors and the elderly use electric toothbrushes, because their teeth have a lower pressure tolerance, the second pressure range can be 30 to 200gf. Lowering the second pressure range is beneficial to protecting the dental health of minors and the elderly. The first pressure range can be 0 to 30gf.

[0029] By acquiring the pressure of the brush head through the pressure acquisition module 101, it is determined whether the toothbrush is in the brushing state. When the toothbrush is not in the brushing state, the central processing module 102 acquires the preset first note sequence and obtains the first working frequency and the first working beat according to the first note sequence. The motor 103 vibrates according to the first working frequency and the first working beat, so that the sound generated by the vibration is converted into a preset audio. The audio is a multi-frequency sound with a pleasant melody, which can reduce the discomfort caused by noise when brushing teeth.

[0030] Specifically, the pressure acquisition module 101 includes: a magnetic core and a magnetic field measurement sensor; the magnetic core is located at the motor shaft of the electric toothbrush, the motor shaft includes a front motor shaft or a rear motor shaft, and the magnetic core is used to generate a magnetic field; the magnetic field measurement sensor is located on the motor bracket or motor housing of the electric toothbrush, the line connecting the center point of the magnetic core and the magnetic field measurement sensor is parallel to the motor shaft, and the magnetic field measurement sensor is used to measure the magnetic induction voltage generated by the magnetic core in real time, the magnetic induction voltage being used to characterize the contact pressure of the brush head against the teeth.

[0031] For specific details, please refer to Table 1 for the electromagnetic reading relationship between the contact pressure and the magnetic induction voltage. The deformation position in Table 1 is the swing position of the motor shaft after deformation under the corresponding pressure.

[0034]

[0035] In a specific embodiment, please refer to Figure 2 The system also includes a storage module 201, the output of which is connected to the input of the central processing module 102, and the storage module 201 stores a first note sequence of preset audio.

[0036] Specifically, the electric toothbrush sound control system also includes a storage module 201, which stores a first note sequence of preset audio. The central processing module 102 can read the first note sequence from the storage module 201. The storage module 201 also has an audio interface, through which the first note sequence of peripherals is stored. The audio interface can also modify and update the note sequence in the storage module 201, thereby updating the preset audio and enhancing the enjoyment of brushing teeth. Specifically, the audio interface can be any one of a USB interface, micro interface, type-A interface, type-C interface, or Lightning interface. The storage module 201 may also include a communication module, which can store the preset first note sequence in the storage module 201. The communication module can be any one of a Bluetooth communication module, RFID communication module, ZigBee communication module, or WiFi communication module.

[0037] In a specific embodiment, the system further includes a battery that powers the pressure acquisition module 101, the central processing module 102, and the motor 103. The central processing module 102 also detects the remaining battery power. When the remaining battery power is less than a preset threshold, the central processing module 102 sends a shutdown signal to the motor 103, and the motor 103 receives the shutdown signal and stops working. Specifically, the preset threshold can be 10% of the total battery power. Setting a preset threshold can effectively protect the battery from overuse and extend its lifespan. Specifically, the power source can be a rechargeable power source, such as a nickel-cadmium battery, a nickel-metal hydride battery, a lithium-ion battery, a lithium polymer battery, or a lead-acid battery.

[0038] In a specific embodiment, the system further includes a display module. The input end of the display module is connected to the output end of the central processing module 102. The central processing module 102 sends the remaining battery power value to the display module. The display module can display the current remaining battery power in real time, which can effectively remind the user of the current battery power value to avoid insufficient battery power when brushing teeth.

[0039] In a specific embodiment, the system further includes a sensing module located on the toothbrush handle near the brush head. The sensing module is used to obtain the change in electrical signal relative to the human body during brushing. A central processing module 102, with its input connected to the output of the sensing module, is used to acquire the change in electrical signal, obtain real-time toothbrush motion area data based on the change in electrical signal, and send the toothbrush motion area data to the user terminal to complete the identification of the brushing area during the user's brushing process. The user terminal can be mounted on the toothbrush or be independent of it. The toothbrush motion area data can be refined into 16 areas: upper left, lower left, lower left inner, upper left inner, lower left outer, upper left outer, upper right, lower right, lower right inner, upper right inner, lower right outer, upper right outer, upper middle inner, lower middle inner, lower middle inner, lower middle inner, and lower middle outer.

[0040] The change in electrical signal can include changes in capacitance, infrared light transmission and reception time difference, ultrasonic transmission and reception time difference, and electrical signals converted from ranging sensor signals. The sensing module is not limited to capacitive sensors, but also includes infrared ranging sensors, SAR proximity sensors, ToF ranging sensors, laser ranging sensors, ultrasonic distance sensors, etc. The sensors in the sensing module are not further limited here, and can be one or a combination of several of them.

[0041] Please see Figure 3 The second embodiment of this application provides a method for controlling the sound effect of an electric toothbrush, applied to an electric toothbrush sound effect control system, the method comprising:

[0042] Step 301: The storage module 201 stores the first note sequence of a preset audio.

[0043] Step 302: The pressure acquisition module 101 acquires the current pressure on the brush head of the electric toothbrush;

[0044] Step 303: When the pressure value is within a preset first pressure range, the central processing module 102 acquires the first note sequence, obtains a first working frequency based on the note frequency of the first note sequence, and obtains a first working beat based on the note playback duration of the first note sequence; the first pressure range is less than the second pressure range of the brush head adhering to the teeth when brushing; the working frequency is used to characterize the vibration frequency, and the working beat is used to characterize the vibration duration.

[0045] Step 304: The motor 103 vibrates according to the first working frequency and the first working rhythm.

[0046] By acquiring the pressure on the brush head through the pressure acquisition module 101, it is determined whether the toothbrush is in the brushing state. When the toothbrush is not in the brushing state, the central processing module 102 acquires the note sequence and obtains the first working frequency and the first working beat according to the first note sequence. The motor 103 vibrates according to the first working frequency and the first working beat, so that the sound generated by the vibration is converted into a preset audio. The audio is a multi-frequency sound with a pleasant melody, which can reduce the discomfort caused by noise when brushing teeth.

[0047] In a specific embodiment, please refer to Figure 4 The storage module stores audio, including:

[0048] Step 401: Compile the preset audio into a first note sequence, wherein the first note sequence contains the note frequency and note playback duration of the preset audio;

[0049] Step 402: The storage module stores the first note sequence.

[0050] Specifically, using musical note calibration technology, the note frequencies and playback durations in the preset audio are obtained, and a first note sequence is constructed using these frequencies and durations; the playback duration is the musical beat of the preset audio. By encoding the preset audio into a first note sequence, the preset audio is converted into audio that the central processing module 102 can recognize, thereby transforming the noise from the vibration of the motor 103 into pleasant audio.

[0051] Specifically, please refer to Table 2. Table 2 describes the different note frequencies, that is, the frequency playback duration corresponding to the note playback duration. For example, if the preset audio note is E5, and the playback duration of E5 is 2 seconds, the working frequency is 329.6 Hz, and the playback duration of 329.6 Hz is 0.25 seconds. The playback durations corresponding to different working frequencies constitute the working beats. For example, the playback duration of 329.6 Hz is 0.25 seconds, the playback duration of 261.6 Hz is 0.125 seconds, and the playback duration of 329.6 Hz is 0.125 seconds. Different playback durations constitute the beats of the audio, such as 0.124 seconds being 1 / 8 beat and 0.25 seconds being 1 / 4 beat.

[0052] Table 2. Note Sequence Relationship Table

[0053] 1 Preset audio notes E5 E5 C5 E5 G5 A5 G4 2 Preset audio note playback duration (s) 2 2 1 1 2 1 2 3 The note frequency (Hz) in this application 329.6 329.6 261.6 329.6 392 440 196 4 The duration (s) of the note frequency playback in this application 0.25 0.25 0.125 0.125 0.25 0.125 0.25

[0054] Specifically, according to the preset audio, there are rests between different working frequencies to control the playback and pause of the audio; there are also rise and fall notes to control the pitch of the audio.

[0055] In a specific embodiment, the note frequency is obtained based on the width of the high level in the note sequence. Specifically, the note frequency is changed by controlling the width of the high level in the note sequence. The high level has higher energy and is typically within the range audible to the human ear, such as 20Hz to 20kHz. By changing the width of the high level, the intensity of the note frequency is changed, making the audio converted from the noise of the motor 103 vibration recognizable to the human ear.

[0056] In a specific embodiment, the preset audio is a multi-channel mixer. The central processing module 102 performs level intensity mixing calculations on the multi-channel mixer to obtain a mixing working signal. The mixing working signal is a frequency-varying digital signal, which includes a mixing working frequency and a mixing working beat. The motor 103 vibrates according to the mixing working frequency and the mixing working beat. By synthesizing multi-channel mixers using the fluctuation signals of multiple audio channels, obtaining the mixing working frequency based on the multiple level intensities of the multi-channel mixers, and obtaining the mixing working beat based on the playback duration of the notes in the multi-channel mixers, the noise generated by the vibration of the motor 103 is transformed into more pleasing music.

[0057] In a specific embodiment, the method further includes: when the pressure value exceeds the second pressure range, the central processing module 102 sends a prompt signal, and the motor 103 receives the prompt signal and stops vibrating. Specifically, when the pressure value exceeds 400gf, the central processing module 102 sends a prompt signal to the motor 103, and the motor 103 stops vibrating upon receiving the prompt signal, ensuring that excessive pressure does not damage the teeth during brushing.

[0058] In a specific embodiment, the method further includes: when the pressure value exceeds the second pressure range, the central processing module 102 acquires a preset prompt note sequence, obtains a prompt working frequency based on the note frequency of the prompt note sequence, and obtains a prompt working beat based on the note playback duration of the prompt note sequence; the motor 103 vibrates according to the prompt working frequency and the prompt working beat. Specifically, when the pressure value exceeds 400gf, the central processing module 102 acquires a preset prompt note sequence, which may be a buzzer sound; it obtains the prompt working frequency and the prompt working beat based on the buzzer sound, wherein the prompt working beat of the buzzer sound is usually a long beep; the motor 103 vibrates according to the prompt working frequency and the long beep prompt working beat, converting the vibration noise into a buzzer sound, which facilitates alerting the user that the current brush head pressure is too high.

[0059] In a specific embodiment, when the pressure value is within the second pressure range, the central processing module 102 acquires a preset second note sequence, obtains a second operating frequency based on the note frequency of the second note sequence, obtains a second operating beat based on the note playback duration of the second note sequence, and obtains the vibration power of the motor 103 based on the note intensity of the second note sequence. The motor 103 vibrates according to the second operating frequency, the second operating beat, and the vibration power of the motor 103. Specifically, when the pressure value is 100gf, the central processing module 102 acquires the preset second note sequence.

[0060] Specifically, the first pressure range is 0–30 gf, and the second pressure range is 30–200 gf. When the pressure is 10 gf, the bristles are not in contact with the teeth, and the central processing module 102 acquires a preset note sequence to operate. When the pressure is 150 gf, the central processing module 102 acquires a preset second audio sequence. The note frequencies of the second audio sequence are higher than those of the first note sequence, and their purpose is to increase the vibration amplitude of the motor 103 to achieve the effect of cleaning the teeth. When the pressure is 300 gf, the central processing module 102 acquires a prompt note sequence to provide a reminder. Specifically, the central processing module 102 can also acquire the corresponding pressure duration. For example, if the pressure value is 300gf and the duration of maintaining 300gf is short (less than the first preset time), a prompt note sequence is added to the preset brushing audio sequence to remind the user that the brushing pressure is too high. When the pressure value is 300gf and the duration of maintaining 300gf is longer (greater than or equal to the first preset time), the central processing module 102 only acquires the prompt note sequence for prompting, and the prompt note sequence is a strong, rapid reminder sound. In addition, when the pressure value exceeds 200gf and the duration is long, the motor 103 can also stop vibrating to prevent excessive pressure from damaging the teeth.

[0061] In a specific embodiment, when the pressure applied to the brush head is within the second pressure range, the current operating frequency threshold is determined to be 100Hz to 350Hz based on the natural frequency of the eyeball, the natural frequency of the tooth root, and ergonomics. Specifically, according to ergonomics, the human body is divided into different parts, and the most sensitive frequency that different parts of the body can perceive relative to environmental vibrations is measured. This most sensitive frequency is called the "natural frequency." Ergonomic measurements show that the natural frequency of the human eyeball is 40-100Hz, the natural frequency of the tooth root is above 434Hz, and the natural frequencies of other human organs are in the infrasound range (less than 20Hz). To ensure that the current operating frequency of the brush head minimizes the impact of the frequency generated by the vibration of the motor 103 during brushing on the human body, the current brushing operating frequency is set to 100Hz to 350Hz, referencing the natural frequencies of the eyeball and tooth root. This 100Hz to 350Hz range avoids the natural frequency range of the eyeball and tooth root, minimizing the impact of the frequency generated by the vibration of the motor 103 on human organs, while also ensuring the efficient cleaning effect of the brush head.
