[0043] Most fascia guns on the market rely on motors to drive the massage head to vibrate at a single frequency or in a fixed pattern. Although users can manually adjust the intensity of vibration to select different levels, the overall vibration pattern lacks dynamic variation, resulting in a monotonous massage experience that fails to meet the diverse relaxation needs of users.

[0044] This utility model proposes a fascia gun control circuit.

[0045] Please see Figure 1 In one embodiment of this utility model, the fascia gun includes a massage head and a motor for driving the massage head to vibrate. The fascia gun control circuit includes:

[0046] Drive circuit 01 is connected to the motor and is used to drive the rotation of the motor.

[0047] Audio input circuit 02 is used to collect music signals from the external environment;

[0048] The control module 03 is connected to the drive circuit 01 and the audio input circuit 02 respectively. The control module 03 controls the drive circuit 01 to drive the motor based on the music signal.

[0049] It should be noted that fascia guns primarily use an internal motor to drive the massage head to vibrate at high frequencies, thereby providing deep relaxation of muscles and fascia, which in turn helps users improve blood circulation, relieve muscle pain, and restore muscle function.

[0050] In this embodiment, the audio input circuit 02 can collect music signals from the external environment. The control module 03 receives the music signals and detects the tempo of the music based on these signals. It then outputs corresponding control commands based on the tempo. The drive circuit 01 can adjust the motor speed according to these control commands, matching the motor speed to the tempo of the music. When the music tempo is fast, the motor speed is increased, resulting in a faster vibration frequency of the massage head. Conversely, when the music tempo is slow, the motor speed is decreased, resulting in a slower vibration frequency of the massage head. Thus, this embodiment can dynamically match the motor speed to the music tempo, optimizing the relaxation effect, enhancing the relaxation experience, and expanding the application potential of fascia guns in sports rehabilitation, entertainment, and relaxation scenarios. It also solves the problem that existing fascia guns offer a relatively monotonous massage experience, failing to meet the diverse relaxation needs of users, and enhances the enjoyment of massage.

[0051] In this embodiment, the control module 03 can set a maximum rotation speed to prevent muscle damage caused by excessively high motor speed; and / or set a minimum rotation speed to prevent the motor speed from being too slow and affecting the massage effect of the fascia gun. In this embodiment, the control module 03 may include a processor that analyzes the beat information corresponding to the music signal. For example, the processor can perform preprocessing on the music signal, such as noise removal and signal amplification, and convert the time-domain signal into a frequency-domain signal for frequency analysis using Fast Fourier Transform combined with peak detection. It then searches for peak values ​​corresponding to the beat frequency in the spectrum and calculates the tempo by calculating the time interval between peak values. Thus, the processor can determine the target vibration frequency of the massage head based on the calculated beat information and control the motor speed by outputting a PWM (Pulse Width Modulation) signal with a corresponding duty cycle. In this embodiment, the control module 03 can control the motor speed using a PID algorithm to prevent sudden speed changes.

[0052] It should be noted that the fascia gun can include multiple modes such as normal mode, rhythmic mode, gradual mode, and intermittent mode, which are not limited here. In normal mode, the control module 03 controls the drive circuit 01 to drive the motor to rotate at a fixed speed. At this time, the massage head vibrates at a fixed frequency, which is suitable for daily muscle relaxation. In rhythmic mode, the control module 03 controls the drive circuit 01 to drive the motor to rotate at a rhythmic speed. The motor speed is adjusted according to the tempo of the external music. At this time, the massage head vibrates at a frequency that changes according to the rhythm of the music, which facilitates a personalized massage experience for the user. In gradual mode, the control module 03 controls the drive circuit 01 to drive the motor to start from a low speed, gradually increase to a higher speed, and then slowly decrease, simulating a massage process from gentle to strong and then back to gentle, which helps to deeply soothe muscles. In intermittent mode, the control module 03 controls the drive circuit 01 to drive the motor to rotate intermittently, so that the massage head vibrates periodically, reducing the overstimulation of muscles that may be caused by prolonged continuous vibration.

[0053] In this invention, the audio input circuit 02 can collect music signals from the external environment, and the control module 03 can output corresponding control commands based on these music signals. The drive circuit 01 can adjust the motor speed according to these control commands, so that the motor speed dynamically matches the music beat. Thus, this invention optimizes the relaxation effect, enhances the relaxation experience, and increases the enjoyment of the massage, allowing users to experience a dynamic massage effect while listening to music. This solves the problem that existing fascia guns offer a relatively monotonous massage experience and fail to meet the diverse relaxation needs of users.

[0054] Please see Figure 2 In one embodiment of this utility model, the audio input circuit 02 includes:

[0055] Microphone (MIC) is used to collect music signals from the external environment;

[0056] Amplification and filtering circuit, which is connected to the microphone (MIC), is used to amplify the music signal before output;

[0057] The analog-to-digital converter circuit is connected to the amplification and filtering circuit and the control module 03. The analog-to-digital converter circuit is used to convert the music signal output by the amplification and filtering circuit into a digital signal and output it to the control module 03.

[0058] In this embodiment, the microphone (MIC) can capture music signals from the surrounding environment, the amplification and filtering circuit can remove interference noise and other unnecessary frequency components, and amplify the music signal output by the microphone (MIC), and the analog-to-digital converter (ADC) circuit can convert the continuous analog signal into a discrete digital signal and output it to the control module 03 for processing. The ADC circuit may include an ADC chip to perform analog-to-digital conversion on the music signal output by the amplification and filtering circuit.

[0059] Please see Figure 2 In one embodiment of this utility model, the amplification and filtering circuit includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first capacitor C1, a second capacitor C2, a third capacitor C3, and an amplifier OP.

[0060] The microphone (MIC) is connected to one end of the first capacitor C1, and the other end of the first capacitor C1 is connected to the first resistor R1. The other end of the first resistor R1 and one end of the fourth resistor R4 are connected to the non-inverting input terminal of the amplifier OP. The other end of the fourth resistor R4 is connected to the first power supply terminal VCC1 of the amplification and filtering circuit. The inverting input terminal of the amplifier OP, one end of the second resistor R2, and one end of the third resistor R3 are connected to the second power supply terminal VCC2 of the amplification and filtering circuit. The other end of the second resistor R2 is connected to one end of the second capacitor C2, and the other end of the second capacitor C2 is grounded. The other end of the third resistor R3, the output terminal of the amplifier OP, and one end of the third capacitor C3 are connected to one end of the fifth resistor R5. The other end of the fifth resistor R5 is connected to the control module 03.

[0061] In one embodiment, the amplification and filtering circuit further includes a sixth resistor R6, a seventh resistor R7, an eighth resistor R8, and a fourth capacitor C4;

[0062] Among them, one end of the sixth resistor R6 is grounded to one end of the fourth capacitor C4, the other end of the sixth resistor R6, the other end of the fourth capacitor C4, one end of the seventh resistor R7 is connected to one end of the eighth resistor R8, the other end of the eighth resistor R8 is connected to the microphone MIC, and the other end of the seventh resistor R7 is connected to the second power supply terminal VCC2 of the amplification and filtering circuit.

[0063] In this embodiment, the microphone (MIC) is used to collect music signals from the external environment and input these signals to the non-inverting input of amplifier OPOP1 via the first capacitor C1. The first capacitor C1 acts as a DC-blocking and AC-passing capacitor, isolating the DC bias and allowing only the AC audio signal to pass through. The first resistor R1 and the fourth resistor R4 form an input impedance matching network to ensure good signal transmission characteristics between the microphone (MIC) and amplifier OP. Amplifier OPOP1 forms a non-inverting amplifier circuit structure to amplify the weak music signal from the microphone (MIC) to achieve the input amplitude range required by the analog-to-digital converter (ADC). The third resistor R3, the second resistor R2, and the second capacitor C2 form a feedback network to adjust the voltage gain of amplifier OP. The third capacitor C3 and the fifth resistor R5 form an RC filter network at the output, further smoothing the amplified signal, suppressing high-frequency interference, and improving the signal-to-noise ratio. Thus, this embodiment, through amplification, filtering, and impedance matching of the audio signal, provides a high-quality signal foundation for subsequent analog-to-digital conversion and beat recognition.

[0064] Please see Figure 3 In one embodiment of this utility model, the driving circuit 01 includes a ninth resistor R9, a tenth resistor R10, an eleventh resistor R11, a twelfth resistor R12, a first diode D1, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, and a first switching transistor Q1.

[0065] Among them, one end of the ninth resistor R9 is connected to the drive signal terminal of the control module 03, the other end of the ninth resistor R9 and one end of the tenth resistor R10 are connected to the controlled terminal of the first switch Q1, the first terminal of the first switch Q1, one end of the eleventh resistor R11 and one end of the twelfth resistor R12 are connected to one end of the sixth capacitor C6, the other end of the tenth resistor R10, the other end of the eleventh resistor R11, the other end of the sixth capacitor C6 and one end of the seventh capacitor C7 are grounded, the second terminal of the first switch Q1, the positive terminal of the first diode D1 and one end of the fifth capacitor C5 are connected to the first power supply terminal of the motor M1, the negative terminal of the first diode D1, the other end of the fifth capacitor C5 and the second power supply terminal of the motor M1 are connected to the power supply terminal of the drive circuit 01, and the other end of the twelfth resistor R12 and the other end of the seventh capacitor C7 are connected to the feedback signal terminal of the control module 03.

[0066] In this embodiment, the first switch Q1 can be an NMOS transistor. The source of the NMOS transistor is the first terminal of the first switch Q1, the drain of the NMOS transistor is the second terminal of the first switch Q1, and the gate of the NMOS transistor is the controlled terminal of the first switch Q1.

[0067] In this embodiment, the control module 03 outputs a PWM signal, which is input to the gate of the NMOS transistor through the ninth resistor R9. When the PWM signal is high, the NMOS transistor is turned on, its source is grounded, and its drain is connected to the first power supply terminal of the motor M1, forming a loop. The motor M1 is powered on and starts to run. The higher the PWM duty cycle, the higher the average voltage, and the faster the motor M1 rotates; the lower the PWM duty cycle, the lower the average voltage, and the slower the motor M1 rotates, thus achieving precise control of the motor M1's speed. The tenth resistor R10 is connected between the NMOS gate and ground, acting as a pull-down resistor to ensure that the NMOS transistor is in the off state when the control module 03 does not output a signal, avoiding malfunctions. The fifth capacitor C5 is used to filter out power supply noise, stabilize the power supply voltage, and improve the operational stability of the motor M1. The first diode D1 is a freewheeling diode, used to absorb the reverse electromotive force generated by the motor M1 during sudden power outages or commutation, protecting the NMOS transistor from breakdown. Furthermore, this embodiment can also perform current detection to achieve closed-loop control of the motor M1 speed. A feedback signal is led out from the source of the NMOS transistor and output to the control module 03 through the twelfth resistor R12. The circuit consisting of the eleventh resistor R11, the twelfth resistor R12, the sixth capacitor C6, and the seventh capacitor C7 can filter the output feedback signal. In this way, this embodiment can achieve precise control of the motor M1 speed.

[0068] Please see Figure 4 In one embodiment of this utility model, the motor is a three-phase brushless DC motor M2, and the drive circuit 01 is a three-phase drive circuit. Each phase drive circuit includes a thirteenth resistor R13, a fourteenth resistor R14, a fifteenth resistor R15, a sixteenth resistor R16, an eighth capacitor C8, and a drive chip U1.

[0069] Among them, one end of the thirteenth resistor R13 is connected to the first signal output terminal of the control module 03, one end of the fourteenth resistor R14 is connected to the second signal output terminal of the control module 03, the other end of the thirteenth resistor R13 and one end of the fifteenth resistor R15 are connected to the first signal input terminal G1 of the driver chip U1, the other end of the fifteenth resistor R15 is grounded, the other end of the fourteenth resistor R14 and one end of the sixteenth resistor R16 are connected to the second signal input terminal G2 of the driver chip U1, the other end of the sixteenth resistor R16, the second drive terminal S2 of the driver chip U1, and one end of the eighth capacitor C8 are connected to the power supply terminal VCC4 of the three-phase drive circuit, the other end of the eighth capacitor C8 is grounded to the first drive terminal G1 of the driver chip U1, and the output terminal of the driver chip U1 is connected to the three-phase brushless DC motor M2.

[0070] In one embodiment, the three-phase drive circuit further includes a seventeenth resistor R17, an eighteenth resistor R18, and a ninth capacitor C9;

[0071] Among them, one end of the seventeenth resistor R17 and one end of the ninth capacitor C9 are connected to the current detection terminal IS_DET of the control module 03. The other end of the seventeenth resistor R17, one end of the eighteenth resistor R18, and the other end of the eighth capacitor C8 are connected to the first driving terminal S1 of the driver chip U1. The other end of the ninth capacitor C9 and the other end of the eighteenth resistor R18 are grounded.

[0072] It should be noted that the three-phase brushless motor eliminates the mechanical commutator and brush assembly in traditional motors, avoiding failures caused by wear of these components. Furthermore, the absence of brush noise makes it more suitable for fascia gun applications.

[0073] In this embodiment, the driver chip U1 integrates one NMOS and one PMOS to form a half-bridge structure, which can automatically switch the conduction state of the upper and lower bridge arms according to the input PWM signal. The control module 03 controls the conduction state of the three-phase upper and lower bridge arms through six control signals (UL, UH, VL, VH, WL, WH), so that the three-phase windings of the three-phase brushless motor commutate in a preset order, thereby driving the rotation of the three-phase brushless DC motor M2. Moreover, the control module 03 can collect the drive current through the current detection terminal IS_DET and output corresponding control signals according to the detected drive current to realize closed-loop speed regulation. When the drive current exceeds a preset threshold, an overcurrent protection mechanism is triggered. Thus, this embodiment can improve the stability and safety of the three-phase drive circuit.

[0075] Trigger circuit 04 is connected to control module 03. When triggered by user, trigger circuit 04 outputs a corresponding trigger signal to control module 03 to indicate the operation of control module 03.

[0076] In this embodiment, the trigger circuit 04 may include a power button, a mode switching button, and a speed adjustment button. The power button is used to control the power-on or power-off operation. The mode switching button is used to switch between different vibration modes, such as cycling between normal mode, rhythmic mode, gradual mode, and intermittent mode. The speed adjustment button is used to adjust the motor speed, thereby changing the vibration intensity of the massage head. It should be noted that the trigger circuit 04 may also include pull-up / pull-down resistors and filter capacitors to prevent false triggering caused by button bounce.

[0077] Please see Figure 5 In one embodiment of this utility model, the fascia gun control circuit further includes:

[0078] Indicator circuit 05 is connected to control module 03. Indicator circuit 05 is used to control the corresponding indicator lights to turn on / off according to the control signals output by control module 03.

[0079] In this embodiment, the indicator circuit 05 may include multiple LEDs to indicate information such as power on / off, mode switching, and rotation speed. Thus, the user can determine the current working status of the fascia gun based on the illumination status of the multiple LEDs.
