When an element is referred to as "on" or "under" another element, the element can be "directly" or "indirectly" located on the other element, or there can be one or more intervening elements. The terms "first", "second", "third" and the like are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second", "third" and the like can be explicitly or implicitly included one or more of the features. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0038] In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular architectures, technologies, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0039] Reference can be made to Figure 1 The present application constructs a massage seat cushion 10, which mainly comprises a seat cushion main body 1, a master control assembly 40 (reference can be made to Figure 4 ) and an acoustic wave vibrator 30.

[0040] In order to distinguish the acoustic wave vibrator 30 of the massage seat cushion 10 and the acoustic wave vibrator 30 of the massage backrest 20 appearing below, the acoustic wave vibrator 30 of the massage seat cushion 10 is referred to as a first acoustic wave vibrator 30a below.

[0041] As shown in Figure 1 , the seat cushion main body 1 is used for the user to sit. The master control assembly 40 of the massage seat cushion 10 is arranged in the seat cushion main body 1, and the master control assembly 40 is configured to acquire an audio file, extract and process a preset low-frequency signal in the audio file. The first acoustic wave vibrator 30a is embedded in the upper surface 11 of the seat cushion main body 1, and the first acoustic wave vibrator 30a is configured to convert the processed low-frequency signal into physical vibration.

[0042] It can be explained here that, different from the traditional mechanical massage principle and massage method, the present application adopts an acoustic wave massage method, drives the acoustic wave vibrator 30 to generate vibration energy through acoustic wave signals of specific frequency, can act on the deep muscle tissue, blood vessels, etc. of the human body, especially can penetrate the fascia layer below 8 cm of the human skin, and makes up for the problem of insufficient depth of mechanical massage. The vibration can assist in improving local blood circulation, promoting tissue vitality, and is helpful for stimulating human cell repair, maintaining normal physiological functions of the body and balance of the vegetative nervous system.

[0043] The preset low-frequency signal can be between 16 Hz-160 Hz. Understandably, the frequency band is determined based on the human perception threshold, the response characteristics of muscle tissue and the mechanical resonance characteristics of the acoustic wave vibrator 30. The frequency band can be effectively perceived by the human body, can cover the main frequency range required for massage physiotherapy, and has better comfort and safety, so as to ensure the transmission efficiency of acoustic wave vibration and the overall massage effect. If it is lower than 16 Hz, the amplitude is too large and the rhythm is too slow, the massage effect is weak or brings discomfort, and if it is higher than 160 Hz, the amplitude becomes small and the stimulation is strong, which is not suitable for massage vibration.

[0044] Please refer to Figure 2 , the first acoustic wave vibrator 30a can be arranged in the central region of the seat cushion body 1, so that the user in the seat cushion 10, the acoustic wave vibration can act on the perineum and its surrounding area of the human body. The perineum as a key point in traditional Chinese medicine meridian, its position is located in the lower part of the body, the traditional theory believes that it is related to many meridians. When low-frequency acoustic wave vibration acts on this area, it can form an effect similar to traditional Chinese medicine point stimulation. Therefore, the massage seat cushion 10 provided by the utility model can drive the modern sound wave treatment technology and the traditional Chinese medicine meridian point theory under the drive of the acoustic wave vibration, and form an acoustic wave meridian vibration massage product with the characteristics of traditional Chinese and western medicine combination.

[0045] In addition, please refer to Figure 1 , the massage seat cushion 10 can also include at least one of the control panel 50, the heating assembly 70 and the loudspeaker 60. The heating assembly 70 is provided with a heating source, which is arranged on the upper surface 11 of the seat cushion body 1, for generating heat to heat the human body contact area. The loudspeaker 60 is used to convert other audio signals of the audio file into sound; here it can be understood that the other audio signals can be the remaining audio signals after the low-frequency signals in the audio file are extracted, or the audio signals of another preset frequency band in the audio file except the low-frequency signals. The control panel 50 is connected with the main control component 40 of the massage seat cushion 10, and is used to control and adjust the working state of the seat cushion, the vibration intensity of the acoustic wave vibrator 30, the volume of the loudspeaker 60 and the like.

[0046] The configuration of the massage seat cushion 10 is described below.

[0047] The seat cushion body 1 can be made of high-resilience polyurethane foam material, which has good air permeability and good support effect, and is beneficial to enhance comfort. Of course, the seat cushion body 1 can also be made of other materials, such as memory foam, latex and the like.

[0048] Please refer to Figure 1 , the upper surface 11 of the seat cushion body 1 has a front side and a rear side, and the edge length of the front side is greater than that of the rear side. Here it can be understood that the front side and the rear side of the seat cushion body 1 refer to the direction of the seat cushion in the normal use state as the reference, the side close to the user's thigh direction is the front side, and the side close to the user's hip and adjacent to the backrest is the rear side.

[0049] In some embodiments, the length of the front and rear sides of the seat cushion body 1 can be between 390mm-430mm, for example 400mm, 408mm, 410mm or 420mm. The maximum length of the horizontal two sides (i.e. left and right sides) of the seat cushion body 1 can be between 440mm-480mm, for example 450mm, 457mm, 460mm or 470mm.

[0050] Please combineFigure 1 and Figure 3 Referring to FIG. 1, the upper surface 11 of the seat cushion body 1 is formed with a buttock supporting area 111, two leg supporting areas 112, and a protruding area 113. The buttock supporting area is located at the rear side of the upper surface 11, the two leg supporting areas 112 are located at the front side of the upper surface 11, and the protruding area 113 is located between the two leg supporting areas 112.

[0051] The buttock supporting area and the two leg supporting areas 112 are recessed at the upper surface 11. The rear side edge and the left and right side edges of the upper surface 11 are higher than the buttock supporting area and the two leg supporting areas 112. The height of the buttock supporting area gradually decreases from the rear side edge of the upper surface 11 to the front side area, so that the buttocks can naturally sink, be covered and limited, thereby improving the stability of the buttock force and reducing the tendency of the human body to slide forward on the seat cushion. The height of the leg supporting area gradually increases from the buttock supporting area to the front side edge of the upper surface 11, so that the lower side of the thigh can obtain an upward lifting force, realizing the sharing of the weight of the legs. The protruding area 113 and the left and right side edges can support the thighs and can play a lateral supporting and guiding role for the thighs when the user changes the sitting posture, so that the position of the thighs remains stable, which helps to reduce the diffusion loss of vibration energy.

[0052] A mounting hole is dug in the center area of the upper surface 11 of the seat cushion body 1 for embedding the first acoustic vibrator 30a therein. In some embodiments, the working principle of the acoustic vibrator 30 is similar to that of a bass speaker, which produces sound by driving the diaphragm to vibrate through the coil. The acoustic vibrator 30 is driven by the coil to produce vibration of the massage contact.

[0053] According to the ergonomic design, the upper surface 11 of the seat cushion body 1 has a reference point 114 corresponding to the H point of the human body (for reference Figure 2 ). Understandably, the H point refers to the center of rotation position of the human body at the junction of the buttocks and the thighs in the sitting posture; the reference point 114 corresponds to the center area of the junction of the two leg supporting areas 112 and the buttock supporting area. The distance L0 between the center of the first acoustic vibrator 30a and the reference point 114 can be between 50mm-90mm, for example, 60mm, 68mm, 70mm or 80mm.

[0054] Continuing to refer to Figure 2To ensure that the sound wave vibration can act on the perineum acupoint of the human body, the distance L1 between the center of the first sound wave vibrator 30a and the horizontal edge of the upper surface 11 can be between 200mm and 250mm, for example, 210mm, 220mm, 228mm, 230mm or 240mm. The distance L2 between the center of the first sound wave vibrator 30a and the front edge of the upper surface 11 can be between 170mm and 210mm, for example, 180mm, 190mm, 200mm. The distance L3 between the center of the first sound wave vibrator 30a and the rear edge of the upper surface 11 can be between 200mm and 240mm, for example, 210mm, 218mm, 220mm, 230mm or 240mm.

[0055] Please refer back Figure 1 The massage cushion 10 is provided with a control panel 50, which is arranged on the horizontal front side surface 21 of the massage cushion 10, and can also be arranged on the horizontal left / right side surface. The control panel 50 is provided with a plurality of keys, which can include a first key for switching the working state of the cushion (on / off, sound wave vibrator 30 switch, speaker 60 switch, etc.), a second key for adjusting the vibration intensity of the sound wave vibrator 30, and a third key for adjusting the volume of the music playing.

[0056] Please refer back Figure 4 The main control component 40 of the massage cushion 10 can include an MCU unit 41, a communication unit 42, a frequency division unit 43, a power amplifier module 44, a filter module 45 and a storage unit 46. The MCU unit 41 is used to receive control signals from the control panel 50 and control the working state of the communication unit 42 and the like according to the control signals. The communication unit 42 is used to communicate with external devices to obtain audio files and output the audio files to the frequency division unit 43. The frequency division unit 43 is used to process the audio files, extract the low-frequency signals therefrom and output the low-frequency signals to the power amplifier module 44. The power amplifier module 44 is a digital power amplifier module 44, which is used to amplify the input digital signals, including low-frequency signals. The filter module 45 is arranged at the rear end of the power amplifier module 44, which is used to filter out the interference components in the amplified signals and restore the digital signals to analog signals. The storage unit 46 is used to store data, including audio files.

[0057] Here it can be understood that the low-frequency signals in the audio files are extracted and processed through amplification, filtering, digital-to-analog conversion and the like; then, the low-frequency signals converted to analog signals are output to the sound wave vibrator 30, so that the sound wave vibrator 30 generates physical vibration, and the vibration frequency corresponds to the frequency of the low-frequency signals.

[0058] In some embodiments, the main control assembly 40 of the massage cushion 10 is configured with a Bluetooth IC, which has a communication function and can be wirelessly connected to external devices such as mobile phones as the communication unit 42. Through cooperation with APP or applets, the control of various functions of the massage cushion 10 can be realized, and audio file resources can be obtained from the server for driving the sound wave vibration of the sound wave vibrator 30.

[0059] Of course, other types of wireless communication chips such as WiFi modules, 4G / 5G communication modules, and NFC modules can also be configured on the main control assembly 40 as the communication unit 42. Through wireless network connection, remote data transmission, cloud audio resource acquisition, and remote control functions can be realized.

[0060] It should be noted here that in related technologies, some Bluetooth ICs are internally integrated with MCU chips, which can directly realize external control logic, so in some embodiments, such Bluetooth ICs can simultaneously serve as the communication unit 42 and the MCU unit 41, performing the dual functions of communication processing and control processing. Further, some advanced Bluetooth ICs also have DSP (digital signal processing) functions, which can perform digital frequency division processing on audio files, thereby directly extracting low-frequency signals inside the chip and outputting them to the power amplifier module 44. By integrating a DSP module in the Bluetooth IC, the need for an independent frequency division unit 43 can be reduced, which is beneficial to reducing circuit complexity.

[0061] The frequency division unit 43 can be implemented in hardware or software. Hardware frequency division can be achieved through a hardware filter, which can be a Chebyshev filter. Compared with conventional hardware filters, the Chebyshev filter can more effectively reduce the entry of other frequency components into the low-frequency channel, thereby improving the accuracy of low-frequency extraction. Software frequency division can be achieved through software frequency division processing of audio files by a DSP chip. Compared with hardware frequency division, software frequency division has higher flexibility and more precise frequency division effect, and can perform gain compensation on the low-frequency part. For example, for some light and soothing music, the original low-frequency component is relatively weak, and through DSP frequency division, the low-frequency interval can be moderately boosted, so that the output low-frequency signal can better drive the sound wave vibrator 30, thereby enhancing the vibration effect and user experience.

[0062] Continuing to refer to Figure 1 , the massage cushion 10 is configured with a loudspeaker 60, which is embedded in the horizontal front surface 21 of the massage cushion 10, and of course can also be provided on the horizontal left / right side surfaces.

[0063] Correspondingly, referring to Figure 4The power amplifier module 44 can include a first power amplifier unit 441 for amplifying the low-frequency signal and a second power amplifier unit 442 for amplifying other audio signals of the audio file. The first power amplifier unit 441 and / or the second power amplifier unit 442 can be a class-D power amplifier.

[0064] The filter module 45 includes a first filter unit 451 for filtering out interference in the amplified low-frequency signal and restoring it to an analog signal, and a second filter unit 452 for filtering out interference in the amplified other audio signal and restoring it to an analog signal. The loudspeaker 60 is configured to convert the other low-frequency signal converted to an analog signal into sound emission to act together with the physical vibration generated by the sound wave vibrator 30 on the hearing and touch of the human body to form a closed loop on the senses, thereby strengthening the overall effect of the sound wave massage.

[0065] Please refer to Figure 2 The heat source of the heating assembly 70 is arranged on the center line of the upper surface 11 and located at the rear side of the first sound wave vibrator 30a, so that the heat source can act on the anus and the surrounding area of the human body when the user sits on the massage cushion 10. The blood flow in this area is relatively difficult to circulate in a sitting position, and warm stimulation can improve local comfort, relieve discomfort caused by long sitting, promote local heat relaxation experience, etc. The distance L4 between the center of the heat source of the heating assembly 70 and the center of the first sound wave vibrator 30a can be between 65mm-105mm, for example, 75mm, 85mm or 95mm. The distance L5 between the center of the heat source of the heating assembly 70 and the rear edge of the upper surface 11 can be between 110mm-150mm, for example, 120mm, 130mm, 132mm or 140mm.

[0066] The heating assembly 70 can be an infrared heating assembly 70, an electric heating wire heating assembly 70, a graphene heating film assembly or a flexible heating sheet assembly. The infrared heating assembly 70 can transmit heat to the human body by far-infrared radiation, has good penetration and uniform heating characteristics; the graphene and flexible heating sheet solutions have the advantages of thin thickness, good flexibility, fast heating speed and uniform heating; the electric heating wire or resistance heating structure is stable and reliable, and easy to control. By combining a temperature sensor and a control unit, the heating assembly 70 can be feedback adjusted to achieve constant temperature heating or multi-grade temperature control. It can be explained here that the heating assembly 70 can be connected to the main control assembly 40 of the massage cushion 10 and controlled by the control panel 50 to control the working state of the heating assembly 70. The specific circuit connection mode can refer to related technologies, which will not be described here.

[0067] Further, the massage cushion 10 can be powered by an internal battery or an external power source. In some embodiments, the massage cushion 10 is internally provided with a rechargeable battery module for providing DC power to the main control assembly 40, the first acoustic vibrator 30a, the heating assembly 70, etc., so that the product can work normally without an external power source, thereby improving the portability and adaptability of use. In other embodiments, the massage cushion 10 can also be powered by a wired power adapter, in which case the battery module can serve as a backup power source or be charged while being powered by the wired power source.

[0068] For reference Figure 5 The utility model also constructs a massage kit, which mainly comprises a massage backrest 20 and the above-mentioned massage cushion 10.

[0069] As Figure 5 indicated, the massage backrest 20 mainly comprises a backrest body 2, a main control assembly 40 (for reference Figure 4 ) and a second acoustic vibrator 30b. The backrest body 2 is used for the user to back against, and is provided with a front side surface 21 in contact with the human body. Here, it is understood that the front side of the backrest body 2 refers to the side close to the user's waist as the reference direction of the backrest in the normal use state; similarly, the side facing away from the user's waist is the back side. The main control assembly 40 of the massage backrest 20 is arranged in the backrest body, and the main control assembly 40 is configured to obtain an audio file, extract and process a preset low-frequency signal in the audio file. The second acoustic vibrator 30b is provided with at least one and is embedded in the front side surface 21 of the backrest body; the second acoustic vibrator 30b is configured to convert the processed low-frequency signal into physical vibration.

[0070] Here, it is explained that the massage backrest 20 and the massage cushion 10 can work independently or cooperatively. When the massage backrest 20 and the massage cushion 10 work cooperatively, the vibrations of the acoustic vibrators 30 of the massage backrest 20 and the massage cushion 10 can be the same frequency, and the same frequency mode can be synchronously controlled by a unified control signal. For example, the massage backrest 20 and the massage cushion 10 are respectively provided with a communication unit 42, and the two are paired and connected through Bluetooth, WiFi or other wireless communication modes, or the massage backrest 20 and the massage cushion 10 are connected by a wire harness, then one party (such as the main control assembly 40 of the massage cushion 10) serves as the main control end, and sends a unified low-frequency control instruction to the other party, so that the acoustic vibrators 30 of the two parties vibrate at the same frequency and rhythm.

[0071] The configuration of the massage backrest 20 is exemplarily described below.

[0072] The backrest body 2 can be made of high-resilience polyurethane foam. Of course, the backrest body 2 can also be made of other materials, such as memory foam, latex, etc. A strap is arranged on the rear surface of the backrest body 2 to provide a basis for fixing the backrest body 2.

[0073] In some embodiments, the length of the upper and lower sides of the backrest body 2 can be between 470 mm and 510 mm, for example, 480 mm, 490 mm, or 500 mm. The maximum length of the horizontal sides (i.e., the left and right sides) of the backrest body 2 can be between 470 mm and 510 mm, for example, 480 mm, 490 mm, or 500 mm.

[0074] Referring to Figure 6 , the front surface 21 of the backrest body 2 can form a spine passage area 211 and two lumbar support areas 212. The spine passage area 211 is located at the vertical center line of the front surface 21 and extends longitudinally to form a hollow passage for the spine, so that the backrest can support the back without directly pressing the spine area. The two lumbar support areas are arranged on the horizontal sides of the spine passage area 211, respectively, to support the waist and provide stable support to the waist. The lumbar support areas 212 have a slightly convex or arc-shaped surface that conforms to the human back curve. The horizontal edges of the front surface 21 are higher than the lumbar support areas 212, so that the user's back can be wrapped and stably supported when sitting on the backrest.

[0075] As shown in Figure 6 , the second acoustic wave vibrator 30b can be provided with two, which are arranged at the approximate middle area of the front surface 21 of the back cushion body in the horizontal direction. For example, one assembly hole is dug at each of the two lumbar support areas 212 for embedding the second acoustic wave vibrator 30b therein. In this way, when the user leans back on the backrest body 2, the acoustic wave vibration can act on the Shenshu acupoint and its surrounding area of the human body. As an important acupoint located in the waist, the Shenshu acupoint is believed by traditional Chinese medicine to correspond to the kidney area of the human body, and has the health care functions of regulating the tension of the waist muscle group and promoting local blood circulation. By applying low-frequency acoustic wave vibration at this position, the local tissue can be subjected to rhythmic mechanical stimulation, which can help to relieve the fatigue of the waist muscle, improve the stiffness of the waist caused by long sitting, and improve the user's relaxation experience.

[0076] To ensure that the sound wave vibration can act on the Shenshu acupoint of the human body, the distance L6 between the centers of the two second sound wave vibrators 30b can be between 150mm-190mm, for example, 160mm, 167mm, 180mm or 190mm. The distance L7 from the center of any one second sound wave vibrator 30b to the horizontal side edge of the front side surface 21 of the backrest body 2 adjacent to the second sound wave vibrator 30b can be between 140mm-180mm, for example, 150mm, 160mm, 162mm or 170mm. The distance L8 from the center of any one second sound wave vibrator 30b to the lower side edge of the front side surface 21 of the backrest body 2 can be between 220mm-260mm, for example, 230mm, 240mm, 243mm or 250mm.

[0077] The main control assembly of the massage backrest 20 can be configured with reference to the main control assembly 40 of the massage seat cushion 10. Figure 4 The main control assembly of the massage backrest 20 is basically the same as the main control assembly 40 of the massage seat cushion 10, and the main difference is that the main control assembly of the massage backrest 20 needs to be connected to two second sound wave vibrators 30b respectively, so that the low-frequency signal converted into an analog signal can be transmitted to the two second sound wave vibrators 30b respectively. The structure of the second sound wave vibrator 30b can be the same as that of the first sound wave vibrator 30a.

[0078] In addition, the massage backrest 20 can also include a speaker and / or a control panel. The speaker / control panel of the massage backrest 20 can be embedded in the surface of the horizontal left / right side of the massage backrest 20. Here it is understood that the massage backrest 20 does not necessarily have to be configured with a speaker; when only the back is subjected to sound wave massage, the music can also be played through the speaker 60 configured on the massage seat cushion 10 to achieve a closed-loop experience in the sense.

[0079] In summary, the massage seat cushion 10, the massage backrest 20 and the massage kit constitute a music sound wave meridian massage product with the characteristics of traditional Chinese and Western medicine, mainly applied in the field of consumer-level health and health care products. These products are suitable for driving scenarios, home scenarios and office scenarios, and can be used with existing car seats, office chairs, home sofas, etc., to meet the needs of users to relieve fatigue, relax the body and mind, and improve comfort.

[0080] Among them, the massage seat cushion 10 and the massage backrest 20 can convert audio signals into physical vibrations of corresponding frequencies according to audio files of different styles and different tones, thereby solving the problem of fixed traditional massage techniques. The sound wave vibrator 30 can be arranged at a specific position of the massage seat cushion 10 and the massage backrest 20, and can act on the corresponding acupoints and surrounding muscle tissues of the human body. In addition, the utility model can also combine touch and hearing by additionally configuring a speaker 60 to achieve a closed-loop experience in the sense. Users can obtain a more comprehensive experience of physical and mental relaxation under the synchronous action of sound wave vibration and music.
