Description

Technical Field

[0001] This utility model relates to the field of medical and health care technology, and in particular to a massager. Background Technology

[0002] Small massagers work on human tissues through vibration, kneading, or electrical stimulation, effectively stimulating acupoints, relaxing muscles, and promoting local blood circulation. This helps relieve physical fatigue and improve muscle stiffness. Especially in today's fast-paced life, shoulder, neck, and back fatigue caused by long hours of work or study has become a common phenomenon. Portable massagers, due to their small size and ease of operation, are gradually becoming an essential tool for personal health management.

[0003] Currently, users primarily interact with massagers via physical buttons or preset mode switches, such as adjusting vibration intensity using fast, medium, and slow buttons. This design relies on a fixed current output, requiring users to manually switch levels to change the drive current and thus adjust the motor's speed and intensity. However, limited by traditional current regulation circuits (such as bidirectional thyristor conduction angle control or voltage divider resistor adjustment), massagers can only provide a limited number of discrete current values, failing to achieve continuous and smooth intensity changes. For example, some circuits use potentiometers to change the capacitor charging time constant to control motor speed, but their adjustment range and precision are constrained by hardware design. Furthermore, existing technology lacks the ability to synchronize with external ambient music rhythms, failing to dynamically generate drive signals with arbitrary current values ​​based on real-time scenarios, resulting in a monotonous massage experience that fails to meet users' demands for personalized, immersive massage sensations. Utility Model Content

[0004] The main purpose of this invention is to provide a massager that enhances the user experience by increasing the interactive experience of the massager and enabling interaction with the product through audio and music.

[0005] To solve the above problems, the massager includes:

[0006] case:

[0007] A pickup device, wherein the pickup device is disposed on the housing; and

[0008] A voice coil motor is fixed inside the housing; the voice coil motor is configured to receive a first drive signal generated by the pickup device.

[0009] In one embodiment of the present invention, the housing has a first fixed position and a second fixed position, which are located at both ends of the housing along the length of the housing; the pickup device is located at the first fixed position, and the voice coil motor is located at the second fixed position.

[0010] In one embodiment of the present invention, the first fixing position is located on the outer peripheral wall of the housing, and the second fixing position is located inside the housing.

[0011] In one embodiment of the present invention, the massager further includes a vibration motor and a control module, the vibration motor and the control module being disposed within the housing; the control module is electrically connected to the sound pickup device and is configured to convert the first drive signal into a first digital signal; the vibration motor is electrically connected to the control module and is configured to receive the first digital signal.

[0012] In one embodiment of this utility model, the vibration motor is positioned close to the voice coil motor.

[0013] In one embodiment of the present invention, the massager further includes an audio storage module, which is electrically connected to the voice coil motor, and the voice coil motor is further configured to receive a second drive signal generated by the audio storage module.

[0014] In one embodiment of the present invention, the audio storage module is electrically connected to the control module, and the control module is further configured to convert the second drive signal into a second digital signal; the vibration motor is further configured to receive the second digital signal.

[0015] In one embodiment of the present invention, the massager further includes a massage soft sleeve covering the housing; the massage soft sleeve has an expansion port aligned with the pickup port of the pickup device.

[0016] In one embodiment of the present invention, the massager further includes an eccentric motion mechanism disposed within the housing; the eccentric motion mechanism includes a rotary motor and an eccentric tension member, the eccentric tension member being connected to the output end of the rotary motor; the eccentric tension member has a first connecting portion, the massage soft sleeve is provided with an air vent, and the first connecting portion is connected to the bottom of the air vent.

[0017] In one embodiment of the present invention, the first connecting part has a plug connector, the bottom of the air port is provided with a deformation limiting groove, and the plug connector is inserted into the deformation limiting groove;

[0018] The groove opening size of the deformation limiting groove is smaller than the size of the connector.

[0019] In this invention, the massager receives external audio signals, such as music or rhythm, via a pickup device mounted on the housing.

[0027] Please see Figure 1 The massager includes a housing 10, a pickup device 20, and a voice coil motor 30. The pickup device 20 is disposed on the housing 10; the voice coil motor 30 is fixed inside the housing 10; and the voice coil motor 30 is configured to receive a first drive signal generated by the pickup device 20.

[0028] In this invention, the massager receives external audio signals, such as music or rhythmic sounds, via a pickup device 20 mounted on the housing 10. These audio signals are then converted into a first drive signal suitable for driving the voice coil motor 30. The voice coil motor 30, fixed inside the housing 10, generates a magnetic field change upon receiving the drive signal, thereby driving the massage head or related components to produce vibration massage movements. Traditional massagers, limited by their current regulation circuits, can only provide a limited number of discrete current values. This solution, however, utilizes the richness and diversity of audio signals to achieve continuously changing drive signals, resulting in smooth and continuous vibration intensity variations. This satisfies users' needs for different massage intensities, more effectively relieving fatigue and improving muscle stiffness. Simultaneously, by capturing audio signals such as music rhythms and converting them into drive signals to control massage movements, the massager interacts with audio and music, enhancing the enjoyment and immersion of the massage and meeting users' demands for personalized, immersive massage experiences.

[0029] It needs to be explained that the massager has a power supply 90 for supplying power to the electrical components, a circuit board for controlling the operation of the electrical components, various wires for realizing electrical conduction and control, and control buttons for realizing physical control. It can be understood that the power supply 90, circuit board and various wires and other structures with waterproof and dustproof requirements are fixed inside the housing 10, and the control buttons can be set on the housing 10. The outer surface of the housing 10 is covered with a protective structure such as a silicone layer.

[0030] In this embodiment, after the massager power supply 90 is in working condition, when the user is in an environment with ambient music, the pickup port (hole) of the pickup device 20 can capture the external ambient sound (such as music). The diaphragm inside vibrates with the frequency of the sound wave, and converts the sound energy into a continuously changing analog electrical signal (i.e., the original form of the first driving signal) through electromagnetic induction. After the signal is amplified by the power amplifier, it is input to the coil of the voice coil motor 30, causing it to reciprocate in the magnetic field, thereby driving the voice coil motor 30 to vibrate.

[0031] Further, please refer to Figure 1 The housing 10 has a first fixed position 11 and a second fixed position 12, which are located at both ends of the housing 10 along the length direction of the housing 10. The sound pickup device 20 is located at the first fixed position 11, and the voice coil motor 30 is located at the second fixed position 12. In this embodiment, the first fixed position 11 and the second fixed position 12 are located at both ends of the housing 10 along the length direction of the overall structure of the massager. It can be understood that when the overall structure of the massager is straight, the length direction of the overall structure of the massager is a straight line. When the overall structure of the massager has an arc segment, the length direction of the overall structure of the massager is a curve connecting as far as possible from one end to the other. In this way, when the sound pickup device 20 is in the sound pickup state, the sound pickup device 20 can reduce the interference generated by the vibration sound because the vibration motor 40 is located at a relatively far position.

[0032] Please refer to Figure 1The first fixed position 11 is located on the outer wall of the housing, and a limiting groove, screw hole and other fixing structures are provided at the first fixed position 11 for fixing the pickup device 20. The second fixed position 12 is located inside the housing, and the housing 10 is provided with a limiting cavity, buckle and other fixing structures at the second fixed position 12. In this way, the sound waves generated by the vibration of the voice coil motor 30 located at the second fixed position 12 can be further reduced by the isolation of the housing 10 and the attenuation of the distance. The pickup device 20 is located on the outer wall of the housing and is directly exposed to the ambient sound field, avoiding the obstruction of sound waves by the housing 10 (especially in the high frequency range) and improving sensitivity. It is understood that modal analysis (FEA simulation) can be performed during the design stage of the housing 10 to avoid the motor operating frequency band and / or add damping patches (such as constraint layer damping material) inside the housing 10 to reduce the resonance peak and avoid the problem of vibration energy being amplified at the microphone end due to resonance.

[0033] In one embodiment of this utility model, the massager further includes a vibration motor 40 and a control module 50, which are disposed within the housing 10. The control module 50 is electrically connected to a pickup device 20 and is configured to convert a first drive signal into a first digital signal. The vibration motor 40 is electrically connected to the control module 50 and is configured to receive the first digital signal. Specifically, the pickup device 20 (e.g., a microphone) captures ambient sound and generates an analog first drive signal. The control module 50 (e.g., a circuit board integrating a microcontroller or digital signal processor) converts the analog signal into a first digital signal via an analog-to-digital converter (ADC), then performs a Fourier transform on the audio signal to extract its frequency components, and maps the energy distribution of different frequency bands to corresponding vibration parameters (e.g., frequency, intensity). Finally, a digital control signal for driving the vibration motor 40 is generated through a PWM (pulse width modulation) generator, so that the vibration motor 40 outputs a vibration mode that matches the frequency characteristics of the ambient sound. The core hardware of the control module 50 can be a low-power microcontroller (specific model not limited) supporting Fast Fourier Transform (FFT) or a dedicated audio processing chip. It directly controls the drive circuit of the vibration motor 40 through the built-in PWM output port. It does not rely on external filtering or complex algorithms, but only on frequency domain energy analysis to realize the fundamental frequency-vibration mapping, thereby achieving the core function of "ambient sound-driven adaptive vibration". It should be noted that the core concept of this technical solution is to realize adaptive frequency vibration through ambient sound. How to use algorithms to perform analysis, filtering, and selection is beyond the scope of this core concept (it can be understood as further improving the recognition accuracy on the basis of realizing the basic function). The technical solution for this part has already made a clear and complete explanation above, so the analysis, filtering, and selection of audio will not be explained.

[0034] Further, please refer to Figure 1 The vibration motor 40 is positioned close to the voice coil motor 30. Specifically, a limiting space for fixing the vibration motor 40 is provided inside the housing 10. At this time, the vibration motor 40 and the voice coil motor 30 are located at the same end of the housing 10, forming the same vibration part on the massager, thus conforming to the user's usage habits. At the same time, the user can switch different vibration modes by controlling the buttons, so as to achieve a massage sensation of multiple different vibration modes on the same massage part without changing the position of the massager.

[0035] In one embodiment of this utility model, the massager further includes an audio storage module 60, which is electrically connected to a voice coil motor 30. The voice coil motor 30 is also configured to receive a second drive signal generated by the audio storage module 60. The audio storage module 60 is an embedded storage unit (such as a flash memory chip, EEPROM, or SD card) used to store pre-recorded audio waveform data (such as sine waves, square waves, or synthesized signals with specific spectral characteristics). These signals can correspond to different massage modes (such as soothing, deep percussion, intermittent pulse, etc.). The second drive signal enters the voice coil motor 30 after being amplified, so that massage can still be provided through the pre-stored signal in the absence of music or in quiet scenarios, thus expanding the usage scenarios. At the same time, by setting up the audio storage module 60, the massager has a dual drive system of "environmental adaptation + preset mode", which not only retains the fun of interacting with external sounds, but also ensures the stability and repeatability of the massage effect through standardized signals.

[0036] In one embodiment, the audio storage module 60 is electrically connected to the control module 50, which is further configured to convert the second drive signal into a second digital signal. The vibration motor 40 is also configured to receive the second digital signal. In this embodiment, the audio storage module 60 is electrically connected to the control module 50 via a circuit board. The control module 50 (i.e., a microcontroller, without limiting the model of the microcontroller) converts the second drive signal (such as massage waveform data in WAV format) pre-stored in the storage module into a second digital signal (such as a pulse sequence with adjustable duty cycle) through digital-to-analog conversion (DAC) or PWM modulation technology, and directly outputs it to the drive circuit of the vibration motor 40. The vibration motor 40 generates mechanical vibrations that match the pre-stored audio characteristics based on the frequency and duty cycle parameters of the second digital signal (e.g., a 100Hz sine wave corresponds to a 50% duty cycle PWM). Thus, standardized massage output can be achieved without relying on external ambient sound. In this way, by combining two vibration signals with two different motors, at least four massage sensations can be provided to the user.

[0037] Furthermore, the massager also includes a massage soft sleeve 70, which covers the housing 10. The massage soft sleeve 70 has an expansion port, which is aligned with the pickup port of the pickup device 20. In this embodiment, the massage soft sleeve 70 can be made of silicone, thermoplastic elastomer, or other materials, thereby improving the skin-friendliness of the massager when it comes into contact with human tissue and enhancing the comfort of the massage. At the same time, an acoustic filter (the aperture can be set according to actual needs) can be provided on the inner wall of the expansion port to protect the pickup port from being blocked by foreign objects.

[0038] For further information on different massage sensations, please refer to [link / reference]. Figure 1 and Figure 2 In one embodiment, the massager further includes an eccentric motion mechanism 80, which is disposed within the housing 10. The eccentric motion mechanism 80 includes a rotary motor 81 and an eccentric tension member 82, which is connected to the output end of the rotary motor 81. The eccentric tension member 82 has a first connecting portion, and the massage soft sleeve 70 is provided with an air vent 70a. The first connecting portion is connected to the bottom of the air vent 70a. Specifically, the eccentric motion mechanism 80 is located at the end of the housing 10 away from the voice coil motor 30. The rotary motor 81 is connected to the power supply 90 and the circuit board through wires, thereby realizing functions such as on / off and output power. The eccentric tension member 82 is connected to the output shaft of the rotary motor 81 through an eccentric bearing 83. Thus, when the rotary motor 81 is in working condition, the first connecting portion at the free end of the eccentric tension member 82 can generate reciprocating motion. At the same time, the first connecting portion is connected to the bottom of the air vent 70a, thereby changing the volume of the air vent 70a and simulating a new massage sensation on human tissue by inhaling and exhaling air.

[0039] To improve the connection stability between the eccentric tension member 82 and the massage soft sleeve 70, the first connecting part has a plug 821. The bottom of the air port 70a is provided with a limiting groove, and the plug 821 is inserted into the limiting groove. The opening size of the limiting groove is smaller than the minimum size of the plug 821. Specifically, the limiting groove can be formed by an elastic material that is the same as or different from the massage soft sleeve 70. The plug 821 can expand the opening of the limiting groove to enter the limiting groove. The opening of the limiting groove has a tendency to recover its deformation and thus shrinks to firmly connect with other structural parts of the first connecting part, so as to ensure the stability between the eccentric tension member 82 and the massage soft sleeve 70 and prevent them from separating due to vibration or friction during use.

[0040] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
