[0071] Embodiment one

[0072] Please refer to Fig. 2, which is a principle block diagram of a motor vehicle seat with a rhythm adjustment function. It includes: a music obtaining module 111, an audio processing module 112, a resonance module 113;

[0073] The music obtaining module 111 is used to obtain audio information. The music obtaining module 111 can be a Bluetooth device, which is used to communicate with an electronic device to obtain a digital audio signal, and decode and output an analog audio signal. The simplest way is that a communication terminal such as a mobile phone inputs the music information on the mobile phone through the Bluetooth device. The Bluetooth device can adopt a Bluetooth transceiver. The music obtaining module 111 can also be a device that communicates with a communication terminal to obtain music information in other terminals such as mobile phones through an external interface.

[0074] The audio processing module 112 is used to convert the obtained audio signal into an analog audio signal, and to amplify and adjust it. In actual application, the audio processing module 112 generally can include an audio decoding subunit 1121, which is used to convert the obtained audio signal into an analog audio signal; a power amplification circuit 1123, which is used to amplify the analog audio signal output by the audio decoding subunit 1121; and a power adjustment circuit 1122, which is used to adjust the analog audio signal output by the audio decoding subunit 1121.

[0075] The resonant module 113 comprises a diaphragm structure and at least one vibration device, the vibration device is arranged below the seat surface close to the user side of the seat, can be directly attached or can be added with other layers, for playing sound, the diaphragm structure is arranged at the outer end surface of the vibration device and is attached to the seat surface, the diaphragm structure is provided with at least one sub-diaphragm, the sub-diaphragm is attached to the surface of the vibration device to form a resonant module, if there are multiple resonant modules, in the resonance state, the band gap effect based on the principle of local resonance and the band gap effect based on the principle of Bragg scattering caused by the spatial periodicity of the multiple resonant modules,

[0076] In operation, the audio signal is converted into an analog audio signal, amplified and adjusted to drive the vibration device to play sound, each sub-diaphragm of the diaphragm structure forms a resonant module with the vibration device, and the vibration is transmitted to act on the user on the seat, the vibration frequency and / or amplitude are pulsed, so that the massage intensity on the seat changes pulsed with the rhythm of the music.

[0077] When the diaphragm structure containing a series of resonant modules is attached to the surface of the vibration device, the surface of the vibration device can be regarded as a piston vibration unit after the acoustic structure of each resonant module is discretized. On the one hand, multiple resonant modules in the resonance state will produce a band gap effect based on the principle of local resonance and a band gap effect based on the principle of Bragg scattering caused by the spatial periodicity of the multiple resonant modules, thereby effectively suppressing the vibration of the vibration-acoustic structure and the propagation of structure noise in the band gap frequency range. On the other hand, the piston vibration unit and the acoustic structure resonant module placed thereon constitute an acoustic system of "base-spring-mass", i.e. the piston vibration unit is the base, the elastic part of the acoustic structure resonant module is the spring (including a certain damping), and the rigid part of the acoustic structure resonant module is the mass. After passing the resonance frequency of the acoustic system, the vibration amplitude of the mass is smaller than that of the base, and the mass has a large proportion of area, which is sufficient to cover the surface of the base, so that the sound radiation of the base is reduced after passing the surface where the mass is located. Especially when the acoustic structure resonant module is in the anti-resonance state, the vibration amplitude of the rigid part reaches a minimum value, at which time the surface where the rigid part is located has a very small radiation sound resistance, thereby significantly reducing the sound radiation ability of the surface. In addition, the working frequency of the resonant module in the embodiment of the present application is defined as the frequency at which the resonant module can reduce the propagation of air noise in the original vibration-acoustic structure (i.e. without attaching the resonant module), so the resonant module of the present application not only has a strong pulsed vibration effect and a good massage effect, the frequency and / or amplitude are pulsed, the change of the massage intensity on the seat is also pulsed, but also effectively suppresses the vibration of the vibration-acoustic structure and the propagation of structure noise in the band gap frequency range, thereby having a small noise and a good massage effect.

[0078] In this basic, the seat 100 of the embodiment generally includes a chair part and a seat part, and the module 200 with the one-way body conduction structure is arranged on the chair part and the seat part respectively. The module 200 can be arranged separately at the opposite positions of the chair part and the seat part. The module 200 can also be built-in at the corresponding positions of the chair part and the seat part. The surface of the seat looks consistent with the structure of the chair part and the seat part. In this case, the one-way body conduction structure can be laid on the chair body and covered by a skin to form a chair surface. The one-way body conduction structure can replace the sponge in the traditional seat. In this case, a special installation space is arranged in the chair part to accommodate the module 200, or a special mounting part is arranged to mount the module 200. In this case, the chair surface can be used as a conduction surface. It should be noted that the module 200 can be arranged at any position of the seat, such as the back, the hips or the feet. The module 200 can be arranged at any position of the seat. The connection mode of the module 200 and the seat includes but is not limited to magic tape bonding, sewing and glue bonding. The shape and structure of the seat are only examples and are not used to limit the application.

[0079] In the development stage of the specific application level, the module can also be developed separately. The shape and structure can be designed according to the actual application occasion. The present example is only an example.

[0080] Please refer to Figure 1 to Fig. 5 (wherein Fig. 2 includes Figure 2A and Figure 2B Fig. 5 is a diagram including Figure 5A and Figure 5B ), the inventor of our company proposes a seat with a one-way body conduction structure. Fig. 1 is a structural schematic diagram of the seat with the one-way body conduction structure, Figure 2A is a principle diagram of the one-way body conduction structure. Figure 2B System block diagram of audio processing module. Figure 3 is an example diagram of the installed resonance module. Figure 4 is an example diagram of the diaphragm structure 2, Figure 5A is an exploded view of another resonance module, Figure 5B is an assembly diagram of another resonance module.

[0081] The seat includes a seat body, a resonant module comprising at least one vibration source or sound source structure, and a unidirectional conductive structure 1. In practical applications, the conductive surface 4 can be the seat body itself, i.e., the resonant module and the unidirectional conductive structure 1 are directly connected to the seat surface of the seat body. Alternatively, a mass-conducting layer can be provided between the unidirectional conductive structure 1 and the seat surface of the seat body to enhance comfort. When the module is placed outside the seat, the conductive surface 4 can also be an outer packaging layer. The outer packaging layer can be made of leather, imitation leather, and / or fabric, etc. These are just some examples, and the materials of the outer packaging layer are not limited to these.

[0082] The resonant module 113 includes a diaphragm structure 2. The vibration source or sound source is at least one vibration device 31 or 32. The diaphragm structure 2 is provided with at least one sub-diaphragm 24. In this example, it includes two sub-diaphragms 24. Each sub-diaphragm 24 of the left and right sub-diaphragms forms a resonant module with the vibration device. Multiple resonant modules will generate a bandgap effect based on the principle of local resonance and a bandgap effect based on the principle of Bragg scattering caused by the spatial periodicity of multiple resonant modules in the resonant state.

[0083] A unidirectional conductive structure 1, located between the resonant module and the conductive surface, comprises at least one unidirectional conductive cotton layer of a certain thickness. The unidirectional conductive cotton layer itself has a structural space of upright fibers, with the direction of the upright fibers aligned with the direction of acoustic energy transmission. This allows the upright fiber structure of the unidirectional conductive cotton layer to form a unidirectional conductive channel for transmitting acoustic energy from the resonant module to the chair surface body.

[0084] During operation, the audio signal is converted into an analog audio signal and amplified and adjusted to drive the vibration devices 31 and 32 for playback. Each sub-diaphragm 24 of the diaphragm structure forms a resonant module with the vibration device, and the vibration is transmitted through the unidirectional body transmission structure 1 to act on the user on the seat. The vibration frequency and / or amplitude change in a pulse manner, so that the massage intensity on the seat changes in a pulse manner with the rhythm.

[0085] First, let's introduce the resonant structure. As shown in Figure 2, the resonant module includes a diaphragm structure, which is configured to include several sub-diaphragms. Each sub-diaphragm 24 is attached to the surface of the vibration device 31 and 32 to form a resonant sub-unit. Multiple resonant sub-units will generate a bandgap effect based on the principle of local resonance and a bandgap effect based on the principle of Bragg scattering caused by the spatial periodicity of multiple resonant sub-units in the resonant state.

[0086] like Figure 3 , Figure 4As shown, the vibration structure can be set as left vibration device 31 and right vibration device 32, and then the diaphragm structure can be set as first diaphragm structure 21 and second diaphragm structure 22. The first diaphragm structure 21 and the second diaphragm structure 22 can be in the form of an integral, connected by the connecting unit 23, and the first diaphragm structure 21 and the second diaphragm structure 22 are both in the form of an upper and lower symmetrical structure, and the middle is connected by the middle piece connecting unit 26. The first diaphragm structure 21 and the second diaphragm structure 22 in the present example can also be symmetrically arranged, and the first diaphragm structure 21 / second diaphragm structure 22 is also provided with a fit fixing part (mounted with the vibration source 31 / 32) and a plurality of sub-diaphragms 24. The fit fixing part is connected with the vibration device (left vibration device 31 or right vibration device 32) below. Each of the plurality of sub-diaphragms is connected with the fit fixing part on one side, and the other side of the sub-diaphragm is connected with the connecting unit 23. The gap 25 is left between the sub-diaphragms 24. In order to improve the transmission effect, the gap 25 extends from the end of the sub-diaphragm 24 to the tail of the sub-diaphragm 24, and the surface area of the sub-diaphragm 24 gradually decreases in the direction close to the connecting unit. The gap 25 is in the form of a strip, and the shape is arc-shaped. The structure is arranged to improve the vibration wave transmission efficiency. The width and size of the plurality of gaps 25 are mainly arranged to further reduce the damping and improve the vibration energy. The size of the gap can be set according to actual needs.

[0087] As shown, Figure 8 In order for the vibration generated by the left vibration device 31 and the right vibration device 32 to be transmitted to the diaphragm structure 2, the left vibration device 31 and the right vibration device 32 can be designed as follows:

[0088] The two ends of the formed suppression part 312 are in the form of an open cavity, which is used to transmit the vibration generated by the vibration part to the direction of the diaphragm structure 2. The suppression part 312 can be made of an elastic material;

[0089] The conductive connecting part 313 is connected to the end opening of the suppression part 312 close to the diaphragm structure and seals the end, which is used to transmit the vibration to the diaphragm structure 2. The conductive connecting part 313 can be made of a rigid material, and the connection mode of the conductive connecting part 313 and the suppression part 312 can be the mode of glue bonding;

[0090] The vibration part 311 is connected to the other end opening of the suppression part 312 away from the diaphragm structure 2, which is used to generate vibration and conduct to the suppression part 312. The vibration part 311 can be a vibrator, and can also be a music player and the like. The left vibration device 31 and the right vibration device 32 form an acoustic system of “base-spring-vibrator”. The connection mode of the vibration part and the suppression part can also be the mode of glue bonding. In order to better transmit the vibration generated by the vibration part to the diaphragm structure 2, the vibration part and the suppression part are sealed and connected.

[0091] Moreover, in order to facilitate the connection of the conductive connection part with the diaphragm structure 2, lugs 223 can be arranged on both sides of the conductive connection part. The lugs 223 can be symmetrically arranged or asymmetrically arranged. Threaded holes are arranged on the lugs 223. Bolts are screwed into the threaded holes on the lugs 223 and the threaded holes on the connecting unit 26, thereby fixing the diaphragm structure 2 and the left vibration device 31 and the right vibration device 32.

[0092] In the present embodiment, the vibration source structure can be arranged as the left vibration device 31 and the right vibration device 32. When the vibrations generated by the left vibration device 31 and the right vibration device 32 are controlled, the left vibration device 31 and the right vibration device 32 generate waves with the same frequency and opposite transmission directions. The superposition of the two waves with the same frequency and opposite transmission directions forms a standing wave, which can improve the vibration energy and thus improve the vibration effect.

[0093] If the vibration source structure is designed as a single vibration device, in order to generate the standing wave described above, a reflecting plate can be arranged in the transmission direction of the wave generated by the single vibration device. The reflecting plate can be made of metal or non-metal, and the material of the reflecting plate is not limited. The reflecting plate is fixed on the single-body conductive structure 1. The wave reflected by the reflecting plate will form a reflected wave. The reflected wave and the wave generated by the single vibration device will form the standing wave described above due to the same frequency and opposite transmission directions, which will act on the single-body conductive structure 1. The propagation speed of the standing wave is fast, and the vibration effect is excellent.

[0094] In specific applications, the second diaphragm structure and the first diaphragm structure can be the same structure. The lamination fixing part and the vibration source structure are generally rigidly connected. The rigid connection methods include but are not limited to high-strength adhesive, riveting, and bolt and nut fixing methods. In the present embodiment, the bolts 222 are connected and fixed with the bolt holes arranged on the connecting cover of the vibration device through the holes 221 arranged on the diaphragm, thereby fixing the vibration source structure and the diaphragm.

[0095] In operation, the vibration of the left vibration device 31 / right vibration device 32 drives the vibration of the lamination fixing part, which in turn drives the vibration of each sub-diaphragm 24.

[0096] When the sub-membrane 24 of the resonant module is attached to the surface of the vibration source, the surface of the vibration source is regarded as a piston vibration unit after the acoustic structure is discretized by each resonant module. On the one hand, the multiple resonant sub-units can generate a band gap effect based on the principle of local resonance and a band gap effect based on the principle of Bragg scattering caused by the spatial periodicity of the multiple resonant sub-units, thereby effectively suppressing the vibration of the vibration-acoustic structure and the transmission of structure noise in the band gap frequency range. On the other hand, the piston vibration unit and the acoustic structure resonant module placed thereon constitute an acoustic system of "base-spring-vibrator", that is, the piston vibration unit is the base, the elastic part of the acoustic structure resonant module is the spring (including a certain damping), and the rigid part of the acoustic structure resonant module is the vibrator. After passing the resonance frequency of the acoustic system, the vibration amplitude of the vibrator is smaller than that of the base, and the vibrator has a large proportion of area, which is sufficient to cover the surface of the base to a large extent, so that the sound radiation of the base is reduced after passing through the surface where the proton is located. Especially when the resonant sub-unit of the acoustic structure is in the anti-resonance state, the vibration amplitude of the rigid part reaches a minimum value, at which time the surface where the rigid part is located has a very small radiation sound resistance, thereby significantly reducing the sound radiation ability of the surface. In addition, the working frequency of the resonant module in the embodiment is defined as the frequency at which the resonant module can reduce the transmission of air noise in the original vibration-acoustic structure (i.e., without attaching the resonant module), or the suppression result, so the resonant module of the embodiment not only has a very strong pulse vibration effect and achieves an excellent massage effect, the frequency and / or amplitude are generally changed in the form of pulses, so that the massage intensity on the seat changes in the form of pulses following the rhythm of the music, and effectively suppresses the vibration of the vibration-acoustic structure and the transmission of structure noise in the band gap frequency range, has the effect of small noise, and has excellent massage effect.

[0097] As shown in Figure 3 , Figure 4 , in order to better adapt to the shape of the human waist, the shape of the membrane structure 2 can be generally butterfly-shaped, and in order to adapt to the shape of the membrane structure 2, the conductive surface 4 and the one-way body conductive structure 1 are also set to be butterfly-shaped; as shown in Figure 5A to Figure 5B , in order to better fit the shape of the human buttocks, the membrane structure 2 can be rib-shaped or trapezoidal-shaped, and in order to adapt to the rib-shaped or trapezoidal-shaped membrane structure 2, the conductive surface 4 and the one-way body conductive structure 1 are rib-shaped or trapezoidal-shaped.

[0098] The shape of the sub-membrane 24 can be an arc shape with the opening downward, and the shape of the sub-membrane 24 can also be an arc shape with the opening upward. Generally, it is mainly related to the direction of the set conductive direction or the direction that is expected to be enhanced.

[0099] The membrane structure in FIG. 5 can be trapezoidal-shaped, and the sub-membrane thereof can also be corrugated. The corrugated shape is to simulate the form of sound wave transmission in water, and the sound wave transmission speed is fast, which reduces the loss of vibration energy in the transmission process.

[0100] In some embodiments of the present application, the second diaphragm structure 22 is selected to have the same structure as the first diaphragm structure 21, or can be selected to have a different structure. In some embodiments of the present application, the second diaphragm structure 22 is selected to be in communication with the first diaphragm structure 21, or can be separately arranged as an independent structure. Similarly, the first diaphragm structure 21 / second diaphragm structure 22 can be an upper-lower symmetrical structure, or can be an upper-lower asymmetrical structure.

[0101] In some embodiments of the present application, the first diaphragm structure 21 / second diaphragm structure 22 contained in the resonant module is a hollow or solid ring, sheet, plate, film, spring, etc. structure, and the material used can be rubber, silicone, latex, high polymer, metal, composite material, etc. but is not limited thereto. The damping loss factor is generally in the range of 0.01 to 0.9 in actual application. In the present example, the resonant module is integrally processed using a metal material.

[0102] In some embodiments of the present application, in order to be more suitable for the human body structure, a support body 6 can be further added, the support body 6 is composed of a certain soft material, and a accommodating groove 61, 62 adapted to the vibrator is arranged in the support body 6, and the diaphragm structure 2 is arranged on the support body 6.

[0103] Generally, the support body 6 is arranged to adapt to the curvature of the human body, and the curvature of the diaphragm structure is adapted thereto. It can be understood that the diaphragm structure can be a planar sheet or a three-dimensional layer, or can have a curvature, which can be modified according to the installation position and the service human body structure.

[0104] A one-way conductive cotton layer is arranged between the diaphragm structure and the seat body in the present application, and in the present embodiment, the one-way conductive cotton layer generally adopts a SOLA fiber cotton layer. The SOLA fiber cotton of the SOLA fiber cotton layer is a high-elasticity upright fiber cotton, which makes the acoustic energy transmission direction vertically propagate. The high-elasticity upright fiber cotton uses high-elasticity polyester fiber as raw material, is opened by an opening machine, is uniformly distributed by a stirring machine, is combed into a fiber web structure by a carding machine, is adjusted into a fiber web with an interlaced structure by a vertical net laying machine, is dried and shaped by an oven, and is cut into a fiber product with an upright structure. The thickness of the SOLA fiber cotton layer is 0.5 cm-50 cm.

[0105] For example, 100% high-elasticity polyester fiber is used as raw material, the melting point of the high-elasticity polyester fiber is 160-220 DEG C, the denier is 1.1D-7D, after opening by the opener, the high-elasticity polyester fiber with different melting points is uniformly distributed by the stirrer, the web is carded into a fiber web structure by the carding machine, the fiber web is adjusted into an interlaced structure by the vertical net machine, and after drying and setting in the oven at about 180 DEG C, the product is cut into a sheet with a regular thickness, that is, high-elasticity straight fiber cotton is formed, and the high-elasticity straight fiber cotton product is cut into a sheet with a regular thickness.

[0106] The SOLA fiber cotton itself has a structure space in the form of straight fibers, the direction of the straight fibers is consistent with the direction of acoustic energy transmission, so that the straight fiber structure of the SOLA fiber cotton layer forms a one-way conduction channel for the resonant module to transmit acoustic energy to the chair body. As shown in FIG. 2, the SOLA fiber cotton can be a layer with a certain thickness, and it should be noted that when arranged, the direction of the straight fiber structure inside the SOLA fiber cotton should be consistent with the direction of sound or vibration propagation. There can be multiple propagation channels formed by multiple straight fibers in the SOLA fiber cotton. It should be noted that the one-way conduction channel is only a logical channel, in simple terms, the direction of sound or vibration propagation is consistent with the direction of the fiber, which forms a so-called one-way conduction channel for transmitting acoustic energy.

[0107] This way can make the one-way conduction of the resonant module to transmit acoustic energy to the chair body have very strong conduction, that is, the conduction of the one-way channel, and the transmission of sound in the remaining directions will be blocked, that is, from the vibrator to the diaphragm, from the diaphragm to the one-way conduction channel of the SOLA fiber cotton to the chair body, forming a good acoustic energy conduction channel, and the remaining directions basically have no sound transmission, that is, achieving the effect of blocking sound transmission in the remaining directions.

[0108] In some embodiments of the present application, a damping layer can also be included, which is located at the opposite end of the SOLA fiber cotton layer of the vibration source or sound source, for blocking the vibration generated by the vibration source structure from being transmitted in the direction away from the chair surface close to the user, forming a better acoustic energy conduction channel.

[0109] In practical applications, the damping layer is generally made of a material with large damping, such as sponge, rubber, and silica gel. The damping layer can be connected to the diaphragm structure 2, so that the resonance module is placed in the space formed between the damping layer and the diaphragm structure 2. The connection between the damping layer and the diaphragm structure 2 can be by glue or by bolts and nuts. The above are only examples and are not intended to limit the present application.

[0110] The high-elasticity upright fiber cotton is composed of filaments with a thickness of 20D-300D. The filaments can be a single filament or a filament bundle. The filament bundle is generally formed by two or more single filaments.

[0111] It should be understood that the SOLA fiber cotton can be arranged between the seat body and the resonance module, or below the vibration source of the resonance module. For example, when arranged below the vibration source, the SOLA fiber cotton can also achieve one-way transmission, such as when the module is directly arranged on the seat, the SOLA fiber cotton below transmits to the surface layer of the seat, and then transmits to the micro parts of the body through the surface layer as a medium, and also achieves the effect of resonance with the water in the body.

[0112] When the diaphragm structure 2 is completely attached to the chair surface, especially when the user sits on the chair, the chair surface contact part attached to the back can allow the diaphragm structure 2 to be attached to this part. The connection unit is located at the chair surface contact part corresponding to the user's spine, and the left vibration device and the first diaphragm structure can act on the left back of the user. It should be understood that the second diaphragm structure and the right vibration device act on the right back of the user. In this way, when the rhythm adjustment device is used, it has a very strong pulse vibration effect, achieving a very strong massage effect. The frequency and / or amplitude change in a pulse manner, so that the massage intensity on the seat changes in a pulse manner with the rhythm of the music, which can provide a strong massage experience to the left and right backs of the user sitting on the chair.

[0113] Considering practicality, after the rhythm adjustment device is arranged on the chair surface of the seat, it can be directly wrapped with cloth, leather, or other chair skins. On the one hand, this achieves the effect of protecting the rhythm adjustment device, and on the other hand, it also achieves the effect of fixing the rhythm adjustment device.

[0114] It should be further noted that multiple rhythm adjustment devices can be arranged on the chair surface from top to bottom. The above-described rhythm adjustment device is only one implementation structure.

[0115] When the seat is set in the non-driver position of the car, several pressure sensors can be installed in the seat cushion and the seat pad respectively. The piezoelectric film sensor and the alarm device are installed at the armrest of the seat, and the installation position of the piezoelectric film sensor can be the place where the user's wrist is placed. The display screen module can be installed at one of the armrests of the seat. The control system and the power module can be located at the bottom of the seat or any one side. The display device is used for music type input, and the user can select elegant and slow songs or passionate rock songs according to his own needs; the display device is also used for output of the user's physical sign data monitored by the piezoelectric film sensor, including blood pressure and pulse, so that the user can know his own physical condition in real time. The wireless communication module is a Bluetooth or Wi-Fi communication device, which is used to send control instructions of the control system to the display screen, and feedback the input information of the display screen to the control system. The power module is used to provide power for the control system and all input and output modules. The pressure sensor, the piezoelectric film sensor and the power module are electrically connected with the input end of the control system, and the specific data monitored by the above monitoring module is transmitted to the control system for processing, including the user's sitting posture and physical sign condition. The rhythm adjusting device, the alarm module and the player module are electrically connected with the output end of the control system. The control system transmits the execution instructions of the processed results to the above modules for execution. The wireless communication module is bidirectionally electrically connected with the control system, and the display screen module is bidirectionally electrically connected with the wireless communication module.

[0116] When the seat is set in the driver position of the car, the application can further include a collection module and a control module,

[0117] The collection module is used to collect information including the current running state of the motor vehicle and / or the current physical state information of the user on the seat;

[0118] The control module is used to control the music obtaining module to output music with different attributes according to the information collected by the collection module, the music with different attributes including music information for exciting the user and music information for relaxing the user,

[0119] And the collection module and the control module form a feedback control. When the driving time exceeds the preset value or the driver is in a fatigue state, the music information for exciting the user is automatically played to alleviate the fatigue state of the driver.

[0120] The present application also provides a rhythm adjustment system, comprising a diaphragm structure and at least one vibration device, the vibration device is used to play sound, the diaphragm structure is arranged on the outer end surface of the vibration device and is attached to the chair surface, the diaphragm structure is arranged to be composed of a plurality of sub-diaphragms, each sub-diaphragm is attached to the surface of the vibration device to form a resonance module, a plurality of resonance modules can generate a band gap effect based on the principle of local resonance and a band gap effect based on the principle of Bragg scattering caused by the spatial periodicity of the plurality of resonance modules,

[0121] In operation, the audio signal is converted into an analog audio signal and is amplified and adjusted to drive the vibration device to play sound, each sub-diaphragm 24 of the diaphragm structure forms a resonance module with the vibration device, and the vibration is transmitted to act on the user.

[0122] Embodiment two

[0123] Based on the embodiment one, as shown in FIG. 2, the vibration device of the present embodiment comprises a first closure part / second closure part arranged outside the left vibration device / right vibration device, the first closure part / second closure part cooperates with the first diaphragm structure 21 / second diaphragm structure 22 to close the left vibration device 31 / right vibration device 32, and a hollow area 33 is further arranged in the first closure part / second closure part, the first diaphragm structure / second diaphragm structure, the first closure part / second closure part and the left vibration device / right vibration device together form an "elastic-vibrator" resonance system.

[0124] Please refer to Figure 10A , taking the left vibration device 31 as an example, the left vibration device 31 generates vibration, the vibration is transmitted to the transmission area b1 in the first diaphragm structure 21, and the sound wave is transmitted to the area f1 above the first diaphragm structure 21, in the present application, f1 can be the transmission surface 4, at the same time, the wave generated by the vibration is also transmitted to the hollow area 33 in the first closure part, the hollow area 33 generally includes the transmission space e1 on both sides of the left vibration device 31 and the d1 area below the left vibration device 31, and the wave is also transmitted to the transmission area a1 inside the first closure part, and a part of the wave is transmitted to the g1 area on both sides of the first closure part and the c1 area below the first closure part.

[0125] In order to achieve better transmission efficiency, the inside of the hollow area 33 can be filled with a SOLA fiber cotton layer, the standing fibers of the SOLA fiber cotton layer are arranged in the same direction as the direction of acoustic energy transmission. The SOLA fiber cotton of the SOLA fiber cotton layer is high-elasticity standing fiber cotton, which is composed of filaments, the thickness of the filaments is 20D-300D, and the filament is a single filament or a filament strip, wherein the filament strip is composed of two or more single filaments.

[0126] The SOLA fiber cotton layer filled in the hollow region 33 includes two modes, one of which (see Figure 10B ), in which the SOLA fiber cotton layer and the first diaphragm structure 21 form a closed structure, covering the left vibration device 31, and in this mode, the wave transmission area is generally only two, one in the b2 area of the first diaphragm structure 21, and the other in the f2 area above the first diaphragm structure 21;

[0127] The other mode is (see Figure 10C ), the SOLA fiber cotton layer, the first diaphragm structure 21 and the upper part of the first closure form a closed area, and in this mode, the wave transmission area generally includes the e2 area formed by the SOLA fiber cotton layer, the first diaphragm structure 21 and the upper part of the first closure, the a2 area in the first closure, the b3 area in the first diaphragm structure 21, the f3 area above the first diaphragm structure 21, the g2 area on both sides of the first closure and the c2 area below the first closure.

[0128] It can be understood that under the same conditions, when the right vibration device 32 generates vibration in the second closure, the wave transmission area is the same as the above-mentioned left vibration device 31 in the first closure.

[0129] Of course, the hollow area inside the hollow region can be empty or filled with other filling materials that are beneficial to transmission.

[0130] From the vibrator to the diaphragm, the acoustic energy conduction channel through the high-elasticity vertical fiber cotton also forms a good conduction channel.

[0131] Example three

[0132] The application can also provide a module with a unidirectional body conduction structure, which includes at least a vibration source or sound source structure, a unidirectional body conduction structure, wherein,

[0133] The vibration source or sound source structure includes a diaphragm structure, and the vibration source or sound source is at least one vibration device. The diaphragm structure 2 is composed of a plurality of sub-diaphragms 24, and each sub-diaphragm 24 forms a resonance module with the vibration device. A plurality of resonance modules in a resonance state can generate a bandgap effect based on the principle of local resonance and a bandgap effect of Bragg scattering principle caused by the spatial periodicity of a plurality of resonance modules;

[0134] The unidirectional body conduction structure is located on at least one side of the resonance module, and at least one SOLA fiber cotton layer with a certain thickness. The SOLA fiber cotton itself has a structure space in the form of vertical fibers, and the direction of the vertical fibers is consistent with the direction of acoustic energy transmission, so that the vertical fiber structure of the SOLA fiber cotton layer forms a unidirectional conduction channel for the resonance module to transmit acoustic energy to the pre-conduction surface,

[0135] In operation, the signal is converted into an analog audio signal and amplified and adjusted to drive the vibration device to play the sound, each sub-membrane of the membrane structure 2 forms a resonance module with the vibration device, and the vibration is transmitted through the one-way body conduction structure, the vibration frequency and / or amplitude is changed in a pulsed manner, so that the massage intensity changes in a pulsed manner with the rhythm.

[0136] The SOLA fiber cotton of the SOLA fiber cotton layer is a high-elasticity upright fiber cotton. High-elasticity polyester fibers are used as raw materials, and after opening by an opener, different melting point polyester fibers are uniformly distributed by a stirrer, and then the cotton web is carded into a fiber web structure by a carding machine. The fiber web is trimmed into an interlaced structure by a vertical net laying machine, and then is dried and shaped by an oven, and is cut into a fiber product with an upright structure. In specific applications, the thickness of the SOLA fiber cotton layer is generally 0.5-50 cm.

[0137] In the above working process, when the vibration structure uses a music player, the sound wave is transmitted to the auditory center. In one case, the human body is used as a sound field, and the transmission path is a one-way body conduction structure that transmits sound waves to the human skeleton. The human skeleton directly transmits the sound waves to the auditory center in the cerebral cortex of the thalamus. In another case, the space around the seat can be used as a sound field for sound wave propagation. The transmission path is that the sound wave is transmitted to the auditory center through the human ear along with the air medium. The specific sequence of transmission to the auditory center through the human ear is the auricle, the external auditory canal, the tympanic membrane, the malleus, the incus, the stapes, the vestibular window, the external and internal lymph, the spiral organ, the auditory nerve, and the auditory center. In the above two transmission paths, the above two sound wave propagation paths can make people hear stereo surround sound. 80% to 95% of the stereo surround sound is heard by people through the human skeleton to directly transmit the sound waves to the auditory center in the cerebral cortex of the thalamus, and the remaining 5% to 20% is heard by people through the human ear to the auditory center.

[0138] Example Four

[0139] A one-way body conduction structure comprises:

[0140] The one-way body conduction structure is located on at least one side of the resonance module, and at least one SOLA fiber cotton layer with a certain thickness. The SOLA fiber cotton itself has a structure space in the form of upright fibers, and the direction of the upright fibers is consistent with the direction of acoustic energy transmission, so that the upright fiber structure of the SOLA fiber cotton layer forms a one-way conduction channel for the resonance module to transmit acoustic energy to the pre-conduction surface.

[0141] During operation, the signal is converted into an analog audio signal and amplified and adjusted to drive the vibration device to play sound. Each sub-diaphragm of the diaphragm structure 2 forms a resonant module with the vibration device, and the vibration is transmitted through the unidirectional body conduction structure. The vibration frequency and / or amplitude change in a pulse manner, so that the massage intensity changes in a pulse manner with the rhythm.

[0142] SOLA fiber cotton is a high-elasticity upright fiber cotton. It uses high-elasticity polyester fiber as raw material. After the cotton is opened by an opening machine, the polyester fibers with different melting points are evenly distributed by a mixer. Then, the cotton web is combed into a fiber web structure by a carding machine. The fiber web is adjusted into an interlaced structure by a vertical web laying machine. Finally, it is dried and shaped in an oven and cut into a fiber product with an upright structure. The thickness of SOLA fiber cotton layer is 0.5cm-50cm.

[0143] To further improve transmission efficiency, a damping layer can be installed at the opposite end of the SOLA fiber cotton layer of the vibration source or sound source. This layer is used to prevent the vibration generated by the vibration source structure from being transmitted in the direction away from the chair surface that is close to the user, thus forming a better acoustic energy transmission channel.

[0144] In practical applications, the damping layer is generally made of a material with high damping, such as sponge, rubber, or silicone. The damping layer can be connected to the diaphragm structure 2, thereby placing the resonant module in the space formed between the damping layer and the diaphragm structure 2. The connection between the damping layer and the diaphragm structure 2 can be achieved by adhesive bonding or bolt and nut connection. The above are just some examples and are not intended to limit the present invention.

[0145] Example 5

[0146] Please see Figure 6 The present invention also provides a volume conduction structure, comprising at least a flexible and rigid material body, the material body including multiple mesh or porous structures, the multiple mesh or porous structures being composed of point structures 41, 42, and 43 in each mesh or porous structure, each point structure 41, 42, and 43 being a target point for wave propagation, the wave being amplified through each target point and propagated to other target points around it through the target point, the faster the conduction speed and the higher the equivalent energy conversion rate;

[0147] During operation, the audio signal is amplified and adjusted to drive the vibration device for playback. The sub-diaphragm 24 of the diaphragm structure 2 forms a resonant module with the vibration device, and the vibrating simple harmonic wave is amplified and transmitted through each target point of the body conduction structure to act on the seat, so that the user's body on the seat and the part in contact with the seat form body conduction.

[0148] The density of the rigid part of the flexible and rigid material body can be 0.1 kg / cm3 to 15 kg / cm3, and the flexibility is the stiffness coefficient with certain self-axial deformation, so that part or all of the flexible and rigid material body acting on the seat after the human body contacts has a certain deformation.

[0149] The rigidity refers to a certain mass, and the flexibility refers to a certain deformation force. When the wave propagates to the material body, the rigidity makes it have a certain vibration, and the flexibility has a certain propagation force. When the wave propagates to the points, the wave is amplified by each target point and conducted to other target points around the target point. When this part is in surface contact with the human body or is attached through other components, the wave can form rapid conduction through the mesh or hole structure, the equivalent energy conversion rate is very high, and the wave can achieve the effect of resonance with the human body, especially with the water in the human body.

[0150] The material body includes a plurality of mesh or hole structures, which are further made of PVC woven material, stainless steel mesh or porous composite material into a single piece or a plurality of pieces combined.

[0151] The body conduction structure can also adopt an aluminum film sandwich structure, and a ring is arranged between the upper fiber layer and the middle fiber layer. The matrix formed by the coil and the ring below the ring is millimeter level. The ring is generally a metal ring. After the coil is energized, a magnetic field is generated. The magnetic field and the vibration generated by the vibration device simultaneously act on the metal ring, which produces a synergistic effect, thereby improving the equivalent energy conversion rate.

[0152] As shown in Figure 7 , in the case where the module 200 is provided with the vibration device 31, 32, the diaphragm structure 2, the one-way body conduction junction structure 1 and the body conduction structure 4, wherein the vibration device 31, 32 is attached and fixed on the diaphragm structure 2, the diaphragm structure 2 is attached and fixed with the one-way body conduction junction 1, and the one-way body conduction junction structure 1 and the body conduction structure 4 are attached and fixed, the vibration transmission mode of the above-mentioned module 200 is that the wave h1 generated by the vibration device 31, 32 is transmitted towards the diaphragm structure 2 direction, a small amount of wave is transmitted away from the diaphragm structure 2 direction, and the wave h2 and h3 transmitted to the diaphragm structure 2 forms a standing wave h4, and the standing wave h4 is transmitted to the one-way body conduction junction structure 1, as shown in Figure 9 , which shows the principle of generating a standing wave by the diaphragm structure 2, wherein k1 and k2 are waves generated by the vibration device, and K3 is a standing wave. The wave h5 formed by the one-way body conduction junction 1 is transmitted to each point structure 41, 42, 43 on the body conduction structure 4 in one direction, and the wave h6 generated by each point structure 41, 42, 43 acts on the human body.

[0153] Example six

[0154] A seat with a body conduction structure, comprising a resonance module including at least a vibration source or sound source structure, a body conduction structure (in this embodiment, the conduction surface adopts a body conduction structure), wherein,

[0155] The resonance module includes a diaphragm structure, the vibration source or sound source is at least one vibration device, the diaphragm structure includes at least one sub-diaphragm 24, the sub-diaphragm 24 and the vibration device form at least one resonance module, and at least one layer of acoustic structure containing the resonance module is constructed on the surface of the sub-diaphragm 24 to discretize the surface of the sub-diaphragm into piston type vibration units;

[0156] In a specific application, the vibration source structure can be arranged as a left vibration device 31 and a right vibration device 32, and then the diaphragm structure can be arranged as a first diaphragm structure 21 and a second diaphragm structure 22. The first diaphragm structure 21 and the second diaphragm structure 22 can be an integral structure connected by a connecting unit 23, and the first diaphragm structure 21 and the second diaphragm structure 22 are an upper and lower structure in itself and are connected by a middle piece connecting unit 26.
