Technical Field
[0001] An audio vibration massage component, its massage chair, and an audio vibration adjustment method are disclosed, particularly an audio vibration massage component, its massage chair, and an audio vibration adjustment method that adjust the vibration mode and intensity according to the frequency and amplitude of an audio signal. Background Technology
[0002] Existing massage chairs primarily use mechanical components to perform kneading, tapping, and rolling massage movements to massage areas such as the shoulders, neck, back, waist, and legs. However, these traditional massage techniques have limited effectiveness in deep relaxation and pain relief, especially for situations requiring deeper stimulation of specific muscle groups.
[0003] While some massage chairs have incorporated vibration modules to enhance the massage effect, most of these vibration technologies operate based on default modes and cannot be adjusted to user needs or external audio signals. Typical designs allow the vibration modules to operate at a fixed frequency, making it difficult to provide a personalized massage experience.
[0004] In addition, some existing massage chairs convert audio signals into vibration modes, but most of them still respond to audio signals in a linear manner, lacking flexibility and making it difficult to adapt to frequency changes, amplitude differences, or rhythm changes in audio signals.
[0005] Therefore, how to develop an audio vibration massage chair that can solve the above problems has become a problem to be solved in the relevant technical field. Summary of the Invention
[0006] To address the aforementioned problems, according to one embodiment, the present invention provides an audio vibration massage chair, including a seat and an audio vibration massage assembly. The seat is for a user to sit on. The audio vibration massage assembly is disposed within the backrest of the seat and includes a frame and massage arms.
[0007] The massage arm is movably mounted on the frame. Each massage arm has at least one kneading massage device, which includes a kneading housing and an audio transducer. The kneading housing has a smooth, rounded surface on its top wall or at the junction of its top and side walls to facilitate kneading massage of the user's body. The audio transducer provides audio vibration massage to the user's body, generating audio vibrations in response to an input audio signal. The kneading housing defines a cavity for receiving the audio transducer, and at least a portion of the top wall of the kneading housing is open to allow for the avoidance of the transducer's vibrating head.
[0008] According to this embodiment, preferably, the audio transducers are also respectively disposed at the foot of the chair seat to provide audio vibration massage to the user's feet.
[0009] According to this embodiment, preferably, each side of the chair seat has a speaker, and the speaker is provided with an audio vibration adjustment module, which is used to determine the vertical vibration adjustment according to the frequency, loudness or rhythm of the audio signal, and to determine the horizontal vibration adjustment according to the amplitude, loudness or rhythm of the audio signal.
[0010] According to this embodiment, preferably, the frequency range of the audio vibration generated by the audio oscillator is 20Hz to 300Hz.
[0011] According to another embodiment, the present invention provides an audio vibration adjustment method, comprising an audio vibration adjustment module receiving an audio signal transmitted by a speaker; the audio vibration adjustment module determining the adjustment of vertical vibration based on the frequency, loudness, or rhythm of the audio signal, and the audio vibration adjustment module determining the adjustment of horizontal vibration based on the amplitude, loudness, or rhythm of the audio signal; and an audio oscillator receiving an audio vibration adjustment signal transmitted by the audio vibration adjustment module and generating audio vibration based on the audio vibration adjustment signal.
[0012] The claimed benefits of this invention include: (1) using sound waves of a specific frequency to deeply stimulate nerve and muscle tissue, effectively promoting blood circulation and muscle relaxation, and providing deeper pain relief. (2) providing multiple vibration modes, automatically selecting the appropriate vibration mode according to time intervals or other conditions, so that massage is not limited to a single rhythm, but can be flexibly varied, increasing the diversity and adaptability of massage.

[0019] To illustrate the various embodiments of the present invention in more detail, the following description is provided with reference to the accompanying drawings. It should be understood that when a component is referred to as "connected" or "set" on another component, it may mean that the component is directly located on the other component, or that there may be an intermediate component connecting the component to the other component. Conversely, when a component is referred to as "directly on another component" or "directly connected to another component," it is understood that this explicitly defines the absence of an intermediate component.
[0020] Furthermore, the terms "first," "second," and "third" are used only to distinguish one component, part, region, or section from another, and not to indicate a necessary order of precedence. Additionally, relative terms such as "lower" and "upper" may be used herein to describe the relationship between one component and another. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in a figure is flipped, a component described as being "lower" than other components would be oriented "upper" than other components. This indicates only a relative orientation, not an absolute one.
[0021] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0022] Please see Figure 1 According to one embodiment, the present invention provides an audio vibration massage chair 1, including a seat 10 and an audio vibration massage component 20. The seat 10 is used for a user to sit on. The audio vibration massage component 20 is disposed inside the backrest of the seat 10. In addition, the audio vibration massage chair 1 has a speaker 22 disposed on the left and right sides at the user's two ear positions respectively.
[0023] Please see Figure 2 , Figure 2The diagram illustrates the structure of an audio vibration massage assembly 20 according to one embodiment of the present invention. The audio vibration massage assembly 20 includes a frame 21 and at least one massage arm 22. The frame 21, serving as the support structure of the audio vibration massage assembly 20, is made of high-strength material to ensure its stability and durability. The massage arm 22 is movably mounted on the frame 21 to accommodate different user postures and massage needs. A kneading massage device 23 is mounted on the massage arm 22. The top wall 2311 of the kneading massage device 23, or the junction of the top wall 2311 and the side wall 2312, is configured as a smooth arc surface to knead and massage areas such as the shoulders, neck, and back. Specifically, the top wall 2311 of the kneading housing 231 is a smooth arc surface with a radius of curvature greater than 10 mm to simulate the kneading motion of fingers, providing a more comfortable massage experience. Furthermore, the top wall 2311 and the side wall 2312 of the kneading housing 231 have a smooth transition, and the radius of curvature at their intersection is greater than 20 mm. This smooth transition design not only helps improve the comfort of the massage, but also avoids friction or discomfort that may occur during the massage, thereby further enhancing the user's overall experience.
[0024] The seat 10 has a speaker 2 on each side. The speaker 2 has an audio vibration adjustment module 3, which is used to adjust the vertical vibration according to the frequency, loudness or rhythm of the audio signal, and to adjust the horizontal vibration according to the amplitude, loudness or rhythm of the audio signal.
[0025] Continue to explain Figure 2 The kneading housing 231 has a dedicated cavity for housing the audio vibrator 232. The cavity design allows the vibrating head of the audio vibrator 232 to operate unobstructed during massage, with at least a portion of the top wall 2311 being open to avoid interference with the vibrating head. The audio vibrator 232 applies audio vibrations to the user's body for massage. The audio vibrator 232 vibrates vertically and horizontally according to the input audio signal. Specifically, the audio vibrator 232 generates audio vibrations based on the audio vibration adjustment signal transmitted by the audio vibration adjustment module 3. The frequency range of the audio vibrations generated by the audio vibrator 232 is 20Hz to 300Hz. The following example illustrates how the audio vibrator 232 generates audio vibrations based on the audio vibration adjustment signal transmitted by the audio vibration adjustment module 3.
[0026] The low-frequency range is approximately 20Hz to 160Hz, the mid-frequency range is approximately 160Hz to 2.5kHz, and the high-frequency range is approximately 2.5kHz and above.
[0027] The intensity of a sound, or its volume, is called loudness or volume. It is primarily affected by amplitude; the larger the amplitude of the sound wave, the greater the loudness and energy, and the farther the sound can travel. The unit is decibel (dB). The higher the decibel value, the greater the loudness. The minimum loudness audible to the human ear is defined as 0 dB. The higher the decibel value, the louder the sound. 10 dB, 20–30 dB, 30–60 dB. Loudness affects the vibration amplitude of the audio transducer 232. When loudness increases, the vertical vibration force also increases, resulting in a stronger sensation. Simultaneously, the horizontal vibration amplitude of the audio transducer 232 increases, providing the user with a stronger lateral pushing and pulling sensation. At lower loudness, the vibration is gentler. At the same time, the horizontal vibration amplitude of the audio transducer 232 decreases.
[0028] Rhythm is a combination of beats of a certain speed, varying note values, and different pitches. For example, 2 / 2 time signature is strong / weak, which is the "boom-cha" we often hear; 3 / 4 time signature is strong / weak / weak, which is the "boom-cha-cha." Most waltzes we hear are in 3 / 4 time, while 4 / 4 time signature is strong / weak / secondary strong / secondary weak. Rhythm can be appreciated independently, such as in percussion music. Rhythm can also form the framework of melodic music. Depending on the rhythm, the frequency and intensity of the vibration of the audio oscillator 232 will adjust accordingly. Faster rhythms result in more frequent vibrations, while slower rhythms result in a more stable and continuous vibration.
[0029] In another embodiment, the present invention can also adjust according to the time segment of the input audio signal to avoid physical fatigue caused by simply following the sound conversion. For example, when the audio oscillator 232 is playing a three-minute piece of music, its vibration intensity will be adjusted according to different time segments of the music:
[0030] 1. First 1 / 3 (seconds 0 to 60): In this section, the vibration intensity of the audio oscillator 232 is set to 1 / 3 of the amplitude and frequency of the audio signal. This means that no matter how loud or rhythmic the music is, the oscillator's vibration amplitude will only reach one-third of the signal amplitude and frequency. This setting is typically used at the beginning of a piece of music to provide a gentler, more relaxing massage sensation, helping the user gradually adapt.
[0031] 2. Middle 1 / 3 (61 seconds to 120 seconds): In this section, the vibration intensity of the audio oscillator 232 may be set to 2 / 3 of the amplitude and frequency of the audio signal. As the music progresses, the vibration intensity gradually increases, resulting in a more significant massage effect. At this point, the massage effect is most intense.
[0032] 3. Last 1 / 3 (121 to 180 seconds): In the final section, the vibration intensity of the audio oscillator 232 can be flexibly adjusted according to the default mode. For example, the vibration intensity may fully respond to the amplitude and frequency of the audio signal, i.e., reach the maximum value of the audio signal, thus bringing the strongest vibration massage effect in the climax of the music, perfectly synchronized with the music rhythm, providing a vibrant and stimulating experience.
[0033] On the other hand, depending on usage needs or comfort settings, the vibration intensity can also be reduced to 1 / 4 of the audio signal amplitude and frequency. This setting is suitable for providing a gentler, more comfortable massage at the end of music, helping users gradually relax their mind and body, avoiding overstimulation, and bringing a softer ending sensation.
[0034] In another embodiment, the present invention can also determine the intensity of vertical vibration based on the frequency, loudness, or rhythm of the input audio signal, thereby producing vibration effects of different magnitudes. Simultaneously, the intensity of horizontal vibration can be determined based on the amplitude, loudness, or rhythm of the input audio signal, thereby producing vibration effects of different levels. For example:
[0035] First audio vibration: When the audio signal frequency is 50Hz, the loudness is 20dB, and the rhythm is relatively slow, the vertical vibration intensity of the audio transducer 232 is relatively small. Under these conditions, the vibration generated by the audio transducer 232 belongs to the low-frequency range and the vibration is relatively gentle.
[0036] Second audio vibration: When the frequency of the audio signal increases to 150Hz, the loudness reaches 40dB, and the rhythm is faster, the vertical vibration intensity of the audio vibrator 232 increases. At this time, the vibration effect produced by the audio vibrator 232 is stronger, belonging to the mid-frequency range, and the massage sensation is more pronounced.
[0037] Third audio vibration: When the amplitude of the audio signal is low (e.g., 2mm), the loudness is 30dB, and the rhythm is slow, the horizontal vibration intensity of the audio transducer 232 is small. At this time, the horizontal vibration generated by the audio transducer 232 is relatively gentle.
[0038] Fourth audio vibration: When the amplitude of the audio signal increases (e.g., 5mm), the loudness reaches 60dB, and the rhythm speeds up, the horizontal vibration intensity of the audio oscillator 232 increases significantly. Under these conditions, the horizontal vibration generated by the audio oscillator 232 is more intense.
[0039] In conclusion, adjusting the intensity of audio vibrations can effectively prevent users from experiencing numbness or fatigue during prolonged massages. If the frequency, intensity, and rhythm of the massage vibrations remain unchanged over a long period, the user's body may gradually adapt to this single stimulus, leading to decreased sensitivity of the nervous system. This weakens the massage effect and may even prevent the desired relaxation or soothing sensation. This numbness reduces overall massage comfort and fails to achieve the ideal muscle relaxation or recovery effect. Therefore, by continuously varying the vibration patterns and intensities, the body's sensitivity to massage can be maintained, enhancing user comfort and achieving better relaxation and recovery results.
[0040] Continue reading Figure 2 The massage arm 22 also includes a first arm 221 and a second arm 222. The kneading massage device 23 is attached to the second arm 222 and connected to the first arm 221 through the second arm 222.
[0041] Please see Figure 3 and Figure 4 , Figure 3 The drawing is a front perspective view of the kneading massage device 23 connected to the second arm 222 according to one embodiment of the present invention. Figure 4 The diagram shows a perspective view of the rear view of the kneading massage device 23 connected to the second arm 222 according to one embodiment of the present invention. The top surface of the audio transducer 232 is designed with a smooth arc surface, allowing the transducer to make close contact with the user's skin during massage, resulting in a gentler and more comfortable massage experience. Furthermore, in the non-massage state, the portion of the top surface of the audio transducer 232 extending beyond the top wall 2311 of the kneading housing 231 is controlled to be less than 10mm. This design ensures the vibration effect while preventing discomfort caused by excessive protrusion of the transducer. In addition, the top wall 2311 and / or the junction of the top wall 2311 and the side wall 2312 of the kneading housing 231 are all configured with smooth arc surfaces to increase the contact area between the kneading massage device 23 and the user's skin, improving massage comfort.
[0042] Continue reading Figure 3 and Figure 4 The second support arm 222 includes a seat plate 2221 and a connecting plate 2222. The seat plate 2221 is arranged horizontally to support the kneading massage device 23. The connecting plate 2222 is used to fix the seat plate 2221 to the first support arm 221. It is arranged vertically and acts as a bridge, making the connection between the second support arm 222 and the first support arm 221 more stable. The audio vibrator 232 and the kneading housing 231 of the kneading massage device 23 are both fixed to the seat plate 2221 at their bottom by bolts or other fasteners, and the connecting plate 2222 is fixed to the first support arm 221 by bolts or other fasteners.
[0043] Please see Figure 5 , Figure 5 The illustration shows a schematic diagram of the foot structure of an audio vibration massage chair 1 according to one embodiment of the present invention. Audio vibrators 232 are not only installed inside the backrest to provide back massage, but are also respectively located at the foot positions of the seat 10 to provide audio vibration to the user's feet. The massage head surface of the audio vibrators 232 is designed with a smooth, rounded arc, which produces a delicate and rhythmic vibration massage on specific areas of the feet to stimulate acupoints and nerve endings on the soles of the feet, thereby promoting blood circulation, relieving foot fatigue, improving sleep quality, and bringing a sense of relaxation and comfort throughout the body. The audio vibrators 232 in the feet work in conjunction with the audio vibrators 232 in the back audio vibration massage assembly through a linkage mode. Specifically, these audio vibrators 232 respond synchronously after receiving the same audio signal, providing the user with a coordinated full-body massage experience through consistent vibration frequency and intensity. When the audio vibrators 232 in the back audio vibration massage assembly vibrate vertically and horizontally according to the frequency and amplitude of the audio signal, the audio vibrators 232 in the feet also vibrate and massage in the same rhythm and pattern.
[0044] In summary, this invention can receive and respond to audio signals, automatically adjust the vibration mode according to the characteristics of the audio signals, and combine with traditional massage techniques to provide diverse vibration modes to enhance the massage experience.
[0045] The above-described embodiments are merely illustrative examples and are not intended to limit the scope of the invention.
