Description

Technical Field

[0001] The present invention relates to the technical field of seats, and particularly to a seat and a module with a unidirectional body conduction device. Background Art

[0002] Combining a sound source and a seat can achieve the effect of vibration massage, and at the same time can play music to soothe the mood. For example, an e-sports seat for sound source health care with the application number 201811067776.X discloses an e-sports seat for sound source health care, including a seat and an intelligent control device. The seat includes a seat cushion and a backrest; the intelligent control device is arranged on the seat cushion and the backrest;

[0003] The intelligent control device includes a controller, a speaker, a music low-frequency vibrator, and a wireless transmission module; the controller is a single-chip microcomputer circuit device, including a main control CPU, a storage unit, a power supply circuit, a key input circuit, a power output circuit, an amplifier circuit, a detection and shaping circuit, an A / D conversion circuit, a display circuit, a digital signal processing DSP electronic frequency divider, and a power amplifier; the wireless transmission module is connected to the controller; the DSP electronic frequency divider includes a high-pass filter and a low-pass filter; the digital signal processing DSP electronic frequency divider and the power amplifier are respectively connected to the main control CPU; the speaker and the music low-frequency vibrator are respectively connected to the power amplifier through the high-pass filter and the low-pass filter in the DSP electronic frequency divider;

[0004] The speaker is arranged at one end of the backrest away from the seat cushion; the music low-frequency vibrator is arranged in the seat cushion and the backrest;

[0005] The controller receives music information through the wireless transmission module and then transmits it to the high-pass filter and the low-pass filter of the DSP electronic frequency divider for filtering. The signal processed by the high-pass filter is output to the speaker for playing, and the signal processed by the low-pass filter is output to the music low-frequency vibrator for output in a vibrating manner.

[0006] When the above-mentioned seat conducts music, since the direction of music conduction is relatively wide, it is easy to have a relatively blurred sound, poor sound field and positioning ability. Due to the phase problem of vibration waves, the sound efficiency will also be reduced. Summary of the Invention

[0007] Aiming at the defects in the prior art, the purpose of the present invention is to provide a seat and a module with a unidirectional body conduction device.

[0008] A seat with a unidirectional body conduction device includes a seat surface body, a resonance module including at least one vibration source or sound source structure, and a unidirectional body conduction component, wherein,

[0009] The resonance module includes a diaphragm structure, and the vibration source or sound source is at least one vibration device. The diaphragm structure is arranged to be composed of several sub-diaphragms, and each sub-diaphragm forms a resonance module with the vibration device. Multiple resonance modules will generate a bandgap effect based on the local resonance principle and a bandgap effect based on the Bragg scattering principle brought by the spatial periodicity of multiple resonance modules in the resonance state;

[0010] The unidirectional body conduction component is located between the resonance module and the chair surface body, and has at least one unidirectional conduction cotton layer with a certain thickness. The structural space of the unidirectional conduction cotton itself is in the shape 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 unidirectional conduction cotton layer forms a unidirectional conduction channel for the resonance module to transmit acoustic energy to the chair surface body,

[0011] During operation, the audio signal is converted into an analog audio signal, amplified and adjusted to drive the vibration device to play. Each sub-diaphragm of the diaphragm structure forms a resonance module with the vibration device, and the vibration is transmitted through the unidirectional body conduction component to act on the user on the seat. The vibration frequency and / or amplitude change in a pulsed manner, so that the massage strength on the seat changes in a pulsed manner with the rhythm.

[0012] The unidirectional conduction cotton of the unidirectional conduction cotton layer is high-elastic upright fiber cotton. It uses high-elastic polyester fiber as raw material. After being opened by an opener, different melting point polyester fibers are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After being adjusted into an interleaved structure by a vertical lapping machine, it is dried and shaped by an oven and cut into a fiber product with an upright structure. The thickness of the unidirectional conduction cotton layer is 0.5 cm - 50 cm.

[0013] The seat further includes a damping layer, which is located at the opposite end of the unidirectional conduction cotton layer of the vibration source or sound source, and is used to prevent the vibration generated by the vibration source structure from being transmitted in the direction away from the chair surface close to the user.

[0014] The vibration device includes a first vibration device and a second vibration device. The bottoms of the first vibration device and the second vibration device are respectively located on both sides inside the chair surface body, and the upper surfaces of the first vibration device and the second vibration device are respectively attached to the lower part of the diaphragm structure or arranged below it through an accommodating space;

[0015] Both the first vibration device and the second vibration device include:

[0016] Both the first vibration device and the second vibration device include:

[0017] An accommodating cavity with both ends open forming a suppression part, which is used to make the vibration generated by the vibration part be transmitted in the direction of the diaphragm structure;

[0018] A conductive connection part is connected to one end of the damping part close to the diaphragm structure and seals this end, and is used for transmitting vibration to the diaphragm structure;

[0019] A vibrating part is connected to one end of the damping part away from the diaphragm structure, and is used for generating vibration and conducting it to the damping part;

[0020] The gap extends from the end of the sub-diaphragm to the tail of the sub-diaphragm, and the surface area of the sub-diaphragm gradually decreases in the direction close to the connection unit;

[0021] During operation, the vibrations of the first vibration device and the second vibration device drive the vibration of the oscillator in contact with the connection part, and then drive the vibrations of each sub-diaphragm.

[0022] The diaphragm structure is butterfly-shaped, and the first diaphragm structure and the second diaphragm structure are fin structures of the butterfly.

[0023] The vibration device includes a left closed part and a right closed part arranged outside the first vibration device and the second vibration device. The left closed part and the right closed part cooperate with the adapted first diaphragm structure and second diaphragm structure to close the first vibration device and the second vibration device. Moreover, a hollow area is provided therein. The first diaphragm structure and the second diaphragm structure, the left closed part and the right closed part and the first vibration device and the second vibration device jointly construct an "elastic-oscillator" resonance system respectively.

[0024] The inner hollow area of the hollow area is filled with a unidirectional conduction cotton layer, and the direction of the upright fibers of the unidirectional conduction cotton layer is consistent with the direction of acoustic energy transmission.

[0025] The unidirectional conduction cotton of the unidirectional conduction cotton layer is high-elastic upright fiber cotton. The high-elastic upright fiber cotton is composed of filaments, with a fineness of 20D - 300D. The filament is a single filament or a filament strip, and the filament strip is composed of two or more single filaments.

[0026] A module with a unidirectional body conduction device at least includes a resonance module of a vibration source or a sound source structure and a unidirectional body conduction component. Among them,

[0027] The resonance module includes a diaphragm structure, the vibration source or the sound source is at least one vibration device, the diaphragm structure is arranged to be composed of several sub-diaphragms, and each sub-diaphragm forms a resonance module with the vibration device. Multiple resonance modules will generate a band gap effect based on the local resonance principle and a band gap effect of the Bragg scattering principle brought by the spatial periodicity of multiple resonance modules in the resonance state;

[0028] The unidirectional body conduction component is located on at least one side of the resonance module and has at least one unidirectional conduction cotton layer with a certain thickness. The unidirectional conduction cotton itself has a structural 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 unidirectional conduction cotton layer forms a unidirectional conduction channel for the resonance module to transmit acoustic energy to the conduction surface.

[0029] During operation, the 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 and the vibration device form a resonance module, and the vibration is transmitted through the unidirectional body conduction component. The vibration frequency and / or amplitude change in a pulsed manner, so that the massage strength changes in a pulsed manner with the rhythm.

[0030] The unidirectional conduction cotton of the unidirectional conduction cotton layer is high-elastic upright fiber cotton. It uses high-elastic polyester fiber as the raw material. After opening the cotton by an opener, the polyester fibers with different melting points are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After the fiber web is adjusted into an interlaced structure by a vertical lapping machine, it is dried and shaped in an oven and cut into a fiber product with an upright structure. The thickness of the unidirectional conduction cotton layer is 0.5 cm - 50 cm.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

It can not only achieve unidirectional transmission of vibration, but also has good softness. When the unidirectional body conduction component is applied to the seat, the unidirectional body conduction component can be laid on the seat body and covered with a skin to form a seat surface, replacing the sponge in the traditional chair. When the vibration source structure is in a working state, the resonance module transmits vibration to the unidirectional body conduction component, and the unidirectional body conduction component transmits the vibration to the seat surface close to the user of the seat. The sound waves transmitted by the unidirectional body conduction component are relatively clear, with accurate positioning, a vast sound field, less loss, high sound wave transmission efficiency, and good vibration feeling.

[0045] The present invention will be described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all belong to the protection scope of the present invention.

[0046] When a person contacts the chair in a lying or sitting position, a dedicated circuit or a sound player is used to play pre-programmed sleep-aiding music or exciting music to drive the oscillator. The sleep-aiding music or exciting music drives the resonance module to vibrate. When the music is played, the vibration of the resonance module acts on the body of the person in contact with the chair in a lying or sitting position. Through bone conduction and based on the resonance principle in physics, the vibration of the resonance module is quickly transmitted to all parts of the body. The water content in the human body is about 60% to 70%. Water can resonate with almost all frequencies. Therefore, the human body will resonate with the frequency of the music, thereby transmitting the vibration and music to all parts of the body, achieving the effect of soothing and regulating the body. In addition to using the basic resonance effect, the sound and vibration of the music can cross the conscious effect and change the brain wave frequency of the person, enabling the person to enter a calm or excited state. Under the action of the resonance principle and consciousness, the body can obtain a deep relaxation or excitement effect, thereby realizing the relaxation of the human body or the excitement of the human body to achieve an effect.

[0047] Basically, the seat 100 of this embodiment generally includes a chair part and a seat part. Modules 200 with unidirectional body conduction components are respectively arranged on the chair part and the seat part. The modules 200 can be set separately and placed at the relative positions of the chair part and the seat part. The modules 200 can also be built into the corresponding positions of the chair part and the seat part. The surface of the seat looks the same as the structures of the above-mentioned chair part and seat part. In this case, the unidirectional body conduction components can be laid on the chair body and covered with a skin to form a seat surface. The unidirectional body conduction components can replace the sponge in a traditional seat. In this case, if a placement space is provided inside the chair part to specifically accommodate its module 200, or a special installation part is provided for installing the module 200, in this case, the seat surface can be used as a conduction surface. It should also be noted that not only can multiple modules 200 be placed at the positions where the seat is needed, but the modules 200 can also be set on the back, buttocks, or even feet of the seat, and can be placed at any position where it is needed. Among them, the connection methods between the module 200 and the seat include but are not limited to methods such as Velcro bonding, sewing, and glue bonding. The shape and structure of the seat are only an example and are not used to limit the present invention.

[0048] During the development process at the specific application level, the module 200 can also be developed separately and can be developed according to specific usage requirements. This example is only for illustration.

[0049] Please refer to Figure 1 Figure 5. Among them, Figure 5 includes Figure 5A and Figure 5B , and the inventors of our company have proposed a seat with a unidirectional body conduction device. Figure 1 It is a schematic structural diagram of a seat with a unidirectional body conduction device; Figure 2Schematic diagram of the exploded structure of an example of a unidirectional body conduction device provided; Figure 3 Schematic diagram of an example of a resonance module; Figure 4 Schematic diagram of a butterfly-shaped diaphragm structure provided by the present invention; Figure 5A Exploded view of another resonance module provided by the present invention; Figure 5B Assembly diagram of another resonance module provided by the present invention;

[0050] The seat 100 includes a seat surface body, a resonance module including at least one vibration source or sound source structure, and a unidirectional body conduction component 1. The label 4 is the conduction surface. The seat surface body can be a resonance module. On this basis, the unidirectional body conduction component 1 is directly in contact with and connected to the seat surface of the seat surface body, or a connection with a certain mass conduction layer that makes people more comfortable can be provided between the unidirectional body conduction component 1 and the seat surface of the seat surface body. When the module is separately provided outside it, the conduction surface 4 can also be an outer packaging layer, and the outer packaging layer can be leather material, leather-like material, and / or cloth, etc. The above are only some examples, and the material of the outer packaging layer is not limited to this.

[0051] The resonance module includes a diaphragm structure 2, and the vibration source or sound source is at least one vibration device 31, 32. The diaphragm structure 2 is provided with at least one sub-diaphragm. In this example, it includes two sub-diaphragm structures, among which, the two sub-diaphragm structures are the first diaphragm structure 21 and the second diaphragm structure 22. Each sub-diaphragm 24 of the first diaphragm structure 21 and the second diaphragm structure 22 forms a resonance module with the vibration device. When multiple resonance modules are in the resonance state, a bandgap effect based on the local resonance principle and a bandgap effect based on the Bragg scattering principle brought by the spatial periodicity of multiple resonance modules will be generated.

[0052] As Figure 6 shown, in order for the vibrations generated by the first vibration device 31 and the second vibration device 32 to be transmitted to the diaphragm structure 2, the first vibration device 31 and the second vibration device 32 can be designed in the following form:

[0053] Form a receiving cavity with both ends open for the suppression part 312, which is used to make the vibration generated by the vibrating part be transmitted in the direction where the diaphragm structure 2 is located. Among them, the suppression part 312 can be made of an elastic material;

[0054] The conduction connection part 313 is connected to and seals the open end of the suppression part 312 close to the diaphragm structure, and is used to transmit the vibration to the diaphragm structure 2. Among them, the conduction connection part 313 can be made of a rigid material, and the connection method between the conduction connection part 313 and the suppression part 312 can be a glue bonding method;

[0055] The vibration part 311 is connected to the other end opening of the suppression part 312 away from the diaphragm structure 2, and is used to generate vibration and conduct it to the suppression part 312. The vibration part 311 can be an oscillator, or a music player, etc. The first vibration device 31 and the second vibration device 32 form an acoustic system of "base-spring-oscillator". The connection mode between the vibration part and the suppression part can also be a glue bonding method. Moreover, 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 hermetically connected.

[0056] Moreover, in order to facilitate the connection between the conduction connection part and the diaphragm structure 2, lugs 223 can be provided on both sides of the conduction connection part. The lugs 223 can be symmetrically arranged or asymmetrically arranged. Corresponding threaded holes are provided on the lugs 223, and bolts are threadedly connected to the threaded holes on the lugs 223 and the threaded holes on the connection unit 26, so as to realize the fixation of the diaphragm structure 2, the first vibration device 31 and the second vibration device 32.

[0057] The unidirectional body conduction component 1 is located between the resonance module and the conduction surface 4, and has at least one SOLA fiber cotton layer with a certain thickness. The SOLA fiber cotton itself has a structural 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 unidirectional conduction channel for the resonance module to transmit acoustic energy to the seat body.

[0058] During operation, the audio signal is converted into an analog audio signal, amplified and adjusted to drive the vibration devices 31 and 32 to play. Each sub-diaphragm of the diaphragm structure forms a resonance module with the vibration devices 31 and 32, and the vibration is transmitted through the unidirectional body conduction component 1 to act on the user on the seat. The vibration frequency and / or amplitude change in a pulsed manner, so that the massage intensity on the seat changes in a pulsed manner with the rhythm.

[0059] First, introduce the resonance structure. As Figure 2 shown, the resonance module includes a diaphragm structure 2, and the diaphragm structure 2 is arranged to include a plurality of sub-diaphragms 24. Each sub-diaphragm 24 is attached to the surfaces of the vibration devices 31 and 32 to form a resonance unit. Multiple resonance units will produce a bandgap effect based on the local resonance principle and a bandgap effect based on the Bragg scattering principle brought by the spatial periodicity of multiple resonance units in the resonance state.

[0060] As Figure 3 、 Figure 4As shown in the figure, the vibration source structure can be set as the first vibration device 31 and the second vibration device 32, and then the diaphragm structure can be set as the first diaphragm structure 21 and the second diaphragm structure. The first diaphragm structure 21 and the second diaphragm structure 22 can be an integral structure, connected by the connecting unit 23, and the first diaphragm structure 21 and the second diaphragm structure 22 are in an up-and-down structure by themselves, and are connected through the intermediate connecting unit 26 in the middle. In this example, the first diaphragm structure 21 and the second diaphragm structure 22 are symmetric structures, and the first diaphragm structure 21 / second diaphragm structure 22 is also an up-and-down symmetric structure. The first diaphragm structure 21 / second diaphragm structure 22 is also provided with an oscillator fitting connection part (the part that fits with the vibration devices 31 and 32 during installation) and several sub-diaphragms 24. The lower part of the oscillator fitting connection part fits with the vibration device (the first vibration device 31 or the second vibration device 32). Each of the several sub-diaphragms is connected to the oscillator fitting connection part on one side and to the connecting unit 23 on the other side. There is a gap 25 between the sub-diaphragms 24. The shape of the gap 25 is strip-shaped and its shape is arc-shaped, which is a structural setting to improve the vibration wave transmission efficiency. Moreover, in order to further improve the vibration conduction 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 settings of the widths and sizes of the multiple gaps 25 are mainly to further reduce the damping and reduce the loss of vibration energy during the transmission process;

[0061] For the convenience of connecting the vibration structure and the diaphragm structure, the first vibration device 31 and the second vibration device 32 can be designed in the following form:

[0062] Both the first vibration device 31 and the second vibration device 32 include a housing. The housing includes a main housing and a connecting cover. The connecting cover is provided with transmission holes for transmitting sound when the vibration component uses a speaker. Lugs are provided on both sides of the connecting cover, and the lugs are connected to the fitting and fixing parts;

[0063] A vibration component, fixed in the accommodation cavity formed by the main housing and the connecting cover, where the vibration component can use a speaker, a vibration motor, etc.

[0064] On the basis of setting the vibration source structure as the first vibration device 31 and the second vibration device 32 above, when controlling the vibrations generated by the first vibration device 31 and the second vibration device 32, the first vibration device 31 and the second vibration device 32 generate waves with the same vibration frequency and opposite transmission directions. The waves with the same frequency and opposite transmission directions will superimpose to form a standing wave, thereby further increasing the vibration energy.

[0065] In addition to the above methods that can generate standing waves, if the vibration source structure is designed as a single vibration device, a reflector for reflecting waves can be set in the transmission direction of the waves generated by the single vibration device. Among them, the reflector can be made of metal or non-metal materials. The reflector can be set on the one-way body conduction component 1. The reflector reflects the waves transmitted to it to form reflected waves. Since the reflected waves and the waves generated by the single vibration device have the same frequency and opposite propagation directions, standing waves will be formed and act on the one-way body conduction component 1. Standing waves have the characteristics of fast propagation speed and good vibration effect.

[0066] The second diaphragm structure 22 is selected to have the same structure as the first diaphragm structure 21. The oscillator fitting connection part and the vibration source structure are generally rigidly connected, and the rigid connection methods include but are not limited to high-strength adhesives, riveting, and the fixing methods of bolts and nuts. In this embodiment, the bolt 222 is connected and fixed to the bolt hole opened on the lug 223 of the connection cover on the vibration source through a plurality of holes 221 provided on the diaphragm, so as to complete the fixation between the vibration source structure and the diaphragm structure.

[0067] During operation, the vibration of the first vibration device 31 / second vibration device 32 drives the vibration of the oscillator fitting connection part, and then drives the vibration of each sub-diaphragm 24.

[0068] When the sub-diaphragm 24 including a series of resonance modules is attached to the surface of the vibration source, the surface of the vibration source can be regarded as a piston-type vibration unit discretized by each resonance module of the acoustic structure. On the one hand, multiple resonator units will generate a bandgap effect based on the local resonance principle and a bandgap effect based on the Bragg scattering principle brought by the spatial periodicity of multiple resonator units in the resonance state, so as to be able to well suppress the vibration of the vibration-acoustic structure and the transmission of structure-borne noise within the bandgap frequency band. On the other hand, the piston-type vibration unit and the acoustic structure resonance module placed on it form an acoustic system of "foundation-spring-oscillator", that is, the piston-type vibration unit is used as the foundation, the elastic part of the acoustic structure resonance module is the spring (including a certain damping), and the rigid part of the acoustic structure resonance module is the oscillator. After crossing the resonance frequency of this acoustic system, the vibration amplitude of the oscillator will become smaller than the vibration amplitude of the foundation as the foundation, and at the same time, the oscillator has a relatively large area and can cover a large area on the surface of the foundation, so that the sound radiation of the foundation becomes smaller after passing through the surface where the proton is located. Especially when the resonance single unit of the acoustic structure is in the anti-resonance state, the vibration amplitude of its rigid part reaches a minimum value, and at this time, the surface where the rigid part is located has a minimum radiation acoustic resistance, so the sound wave radiation ability of this surface can be significantly reduced. In addition, the working frequency of the resonance module in the embodiment of the present invention is defined as the ability of the resonance module to reduce the air noise transmission or suppression result in the original vibration-acoustic structure (that is, when the resonance module is not attached). Therefore, the resonance module in this embodiment not only has a very strong pulsed vibration effect and achieves an excellent massage effect, and the frequency and / or amplitude change in a pulsed form, so that the massage intensity on the seat will change in a pulsed manner following the rhythm of the music, but also effectively suppresses the vibration of the vibration-acoustic structure and the transmission of structure-borne noise within the bandgap frequency band, has the effect of low noise, and has an excellent massage effect.

[0069] As Figures 2 - 4 shown, in order to better adapt to the shape of the human waist, the diaphragm structure can be set in a butterfly shape. When the diaphragm structure is designed in a butterfly shape, the conduction surface 4 and the one-way body conduction component 1 are adaptively set in a butterfly shape.

[0070] As Figures 2 to 4 shown, in order to better adapt to the shape of the human waist, the shape of the diaphragm structure can generally be in a butterfly shape. In order to adapt to the shape of the diaphragm structure, the conduction surface 4 and the one-way body conduction component 1 are also set in a butterfly shape; as Figures 5A to 5B shown, in order to better fit the shape of the human buttocks, the diaphragm structure can be in a rib shape or a trapezoid shape, etc. In order to adapt to the rib-shaped or trapezoid-shaped diaphragm structure, the conduction surface 4 and the one-way body conduction component 1 are in a rib shape or a trapezoid shape.

[0071] The shape of the sub-diaphragm 24 can be an arc with the opening downward, and the shape of the sub-diaphragm 24 can also be an arc with the opening upward. Generally speaking, it is mainly related to the set conduction direction or the direction to be enhanced.

[0072] Figure 4 The diaphragm structure therein can be trapezoidal, and its sub-diaphragms can also be corrugated. The corrugation is to imitate the form of sound wave transmission in water. The sound wave transmission speed is fast, reducing the loss of vibration energy during transmission.

[0073] In some embodiments of the present invention, the second diaphragm structure 22 can be selected to have the same structure as the first diaphragm structure 21, or different structures can be selected. In some embodiments of the present invention, the second diaphragm structure 22 can be selected to be connected to the first diaphragm structure 21, or can be separately disconnected to form independent individual structures. Similarly, the first diaphragm structure 21 / second diaphragm structure 22 can be a vertically symmetric structure or a vertically asymmetric structure.

[0074] In some embodiments of the present invention, the first diaphragm structure 21 / second diaphragm structure 22 included in the resonance module is a hollow or solid ring, sheet, plate, membrane, spring and other structures. The materials used can be rubber, silica gel, latex, polymer, metal, composite materials and other materials, but are not limited thereto. The damping loss factor is generally in the range of 0.01 to 0.9 in practical applications. In this example, the resonance module is integrally processed from a metal material.

[0075] In some embodiments of the present invention, the second diaphragm structure 22 included in the resonance module can be selected to be a hollow or solid ring, sheet, plate, membrane, spring, etc. similar to the first diaphragm structure 21. The materials used can be rubber, silica gel, latex, polymer, metal, composite materials, etc., but are not limited thereto. The damping loss factor of the second diaphragm structure 22 selected and the first diaphragm structure 21 is generally required to be in the range of 0.01 to 0.9. In this example, the resonance module is mainly integrally processed from a metal.

[0076] In some embodiments of the present invention, in order to better adapt to the human body structure, a support 6 can be added. The support 6 is composed of a certain soft material, and accommodation grooves 61 and 62 adapted to the vibrator are provided therein, and the diaphragm structure is arranged on the support 6. Generally, the support 6 is set to adapt to the curvature of the human body, and the curvature of the diaphragm structure will adapt thereto. It can be understood that the diaphragm structure can be a flat sheet or a three-dimensional layer, or can have a curvature, and can be adaptively modified according to the installation position and the human body structure to be served.

[0077] A unidirectional conduction cotton layer can also be arranged between the diaphragm structure of the present invention and the seat body. In this embodiment, the unidirectional conduction cotton layer specifically adopts a SOLA fiber cotton layer. The SOLA fiber cotton of the SOLA fiber cotton layer is a high-elastic upright fiber cotton, which uses high-elastic polyester fiber as the raw material. After being opened by a cotton opener, the polyester fibers with different melting points are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After being adjusted into a staggered structure by a vertical lapping machine, it becomes a fiber product with an upright structure after being dried and shaped in an oven and cut into shape. The thickness of the SOLA fiber cotton layer is 0.5 cm - 50 cm.

[0078] For example, using 100% high-elastic polyester fiber as the raw material, the melting point of the high-elastic polyester fiber is 160°C - 220°C, and the denier is 1.1D - 7D. After being opened by a cotton opener, the high-elastic polyester fibers with different melting points are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After being adjusted into a staggered structure by a vertical lapping machine, it is dried and shaped in an oven at about 180°C, and then cut into shape to form a high-elastic upright fiber cotton with an upright structure. The high-elastic upright fiber cotton product is cut into thin slices with a certain thickness. The SOLA fiber cotton layer can also be processed in the form of mammary glands. Using 100% high-elastic polyester fiber as the raw material, the melting point of the high-elastic polyester fiber is 160°C - 220°C, and the denier is 1.1D - 7D. After being opened by a cotton opener, the high-elastic polyester fibers with different melting points are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After being adjusted into a staggered structure by a vertical lapping machine, it is dried and shaped in an oven at about 200°C and cut into shape to form a high-elastic upright fiber cotton with an upright structure. The high-elastic upright fiber cotton product is cut into thin slices with a certain thickness.

[0079] The SOLA fiber cotton itself has a structure space in the shape 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 unidirectional conduction channel for transmitting acoustic energy to the seat surface body as a resonance module. As Figure 2 shown, the SOLA fiber cotton can be a layer with a certain thickness. Note that when setting, the direction of the upright fibers 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 upright fibers in the SOLA fiber cotton. It should also be noted that the unidirectional conduction channel is only a channel in a logical sense. In simple terms, that is, when the sound or vibration propagation is consistent with the direction of the fibers, a unidirectional conduction channel for transmitting acoustic energy in a logical sense is formed.

[0080] This method can make the one-way conductivity of the resonant module transmitting acoustic energy to the chair surface body have extremely strong conductivity, that is, the conductivity of the one-way channel, while the sound propagation in other directions is blocked. That is, a one-way conduction channel from the oscillator to the diaphragm and from the diaphragm to the SOLA fiber cotton reaches the chair surface body, forming a good acoustic energy conduction channel, and the propagation in other directions is effectively sound-insulated.

[0081] In some embodiments of the present invention, a damping layer may further be included, which is located at the opposite end of the SOLA fiber cotton layer of the vibration source or sound source, and is used to prevent the vibration generated by the vibration source structure from being transmitted in the direction away from the chair surface close to the user, so as to form a better acoustic energy conduction channel.

[0082] The high-elastic upright fiber cotton may be composed of filaments with a fineness of 20D - 300D. The filament is a single filament or a filament strip, and the filament strip is composed of two or more single filaments.

[0083] In fact, the SOLA fiber cotton may be disposed between the seat body and the resonant module, or may be disposed below the vibration source of the resonant module. For example, when disposed at the position below the vibration source, the SOLA fiber cotton also plays a function of one-way transmission. For example, when the module is separately disposed directly on the seat, it is transmitted to the seat surface layer through the SOLA fiber cotton below, and then transmitted through the surface layer as a medium, and can also be transmitted to each tiny part of the body and resonate with the water in the body.

[0084] Second Embodiment

[0085] Based on the first embodiment, as Figure 2 shown, the vibration device of this embodiment includes a left closed part / right closed part disposed outside its first vibration device / second vibration device. The left closed part / right closed part cooperates with the adapted first diaphragm structure 21 / second diaphragm structure 22 to close the first vibration device 31 / second vibration device 32. And a hollow area 33 is further provided therein. The first diaphragm structure / second diaphragm structure, the left closed part / right closed part and the first vibration device / second vibration device jointly construct an "elastic-oscillator" resonant system respectively.

[0086] Please refer to Figure 7A, Taking the first vibration device 31 as an example, the first vibration device 31 generates vibrations. The vibrations are transmitted to the transmission area b1 in the first diaphragm structure 21. At the same time, sound waves pass through the first diaphragm structure 21 and are transmitted to the upper area f1 above the first diaphragm structure 21. In this application, f1 can be the conduction surface 4. Meanwhile, the waves generated by the vibrations are also transmitted to the hollow area 33 in the left closed part. The hollow area 33 generally includes the transmission spaces e1 on both sides of the first vibration device 31 and the d1 area below the first vibration device 31. At the same time, the waves are also transmitted to the transmission area a1 inside the left closed part, and a part of the waves are transmitted to the g1 areas on the left and right sides of the left closed part and the c1 areas on the lower left and right of the left closed part.

[0087] For better conduction efficiency, the inside of the hollow area 33 can be filled with a SOLA fiber cotton layer. The direction of the upright fibers of the SOLA fiber cotton layer is consistent with the direction of acoustic energy transmission. The SOLA fiber cotton of the SOLA fiber cotton layer is high-elastic upright fiber cotton. The high-elastic upright fiber cotton is composed of filaments. The thickness is 20D - 300D. A filament is a single fiber or a fiber strand, and the fiber strand is composed of two or more single fibers.

[0088] There are two ways to fill the SOLA fiber cotton layer in the hollow area 33. One way is (refer to Figure 7B ). In this way, the SOLA fiber cotton layer and the first diaphragm structure 21 form a closed structure, wrapping the first vibration device 31 therein. In this case, the areas where the waves are transmitted are generally only two. One is in the b2 area of the first diaphragm structure 21, and the other area is in the f2 area above the first diaphragm structure 21;

[0089] The other way is (refer to Figure 7C ). The SOLA fiber cotton layer, the first diaphragm structure 21 and the periphery of the upper part of the left closed part form a closed area. In this case, the areas where the waves are transmitted generally include the e2 area formed by the SOLA fiber cotton layer, the first diaphragm structure 21 and the periphery of the upper part of the left closed part, the a2 area inside the left closed part, the b3 area in the first diaphragm structure 21, the f3 area above the first diaphragm structure 21, the g2 areas on both sides of the left closed part, and the c2 areas below the left closed part.

[0090] It can be understood that under the same conditions, when the second vibration device 32 generates vibrations in the right closed part, the areas where the waves are transmitted are the same as those of the first vibration device 31 in the left closed part above.

[0091] Of course, the inner hollow area of the hollow area can be empty or filled with other fillers that are beneficial for transmission.

[0092] From the vibrator to the diaphragm, an acoustic energy conduction channel is formed through highly elastic upright fiber cotton, and similarly, a good conduction channel is also formed.

[0093] Embodiment 3

[0094] The present invention can also separately provide a module with a unidirectional body conduction device, which at least includes a resonant module of a vibration source or a sound source structure and a unidirectional body conduction component. Among them,

[0095] The resonant module includes a diaphragm structure, the vibration source or the sound source is at least one vibration device, the diaphragm structure is arranged to be composed of several sub-diaphragms, each sub-diaphragm forms a resonant module with the vibration device, and multiple resonant modules will generate a bandgap effect based on the local resonance principle and a bandgap effect of the Bragg scattering principle brought by the spatial periodicity of multiple resonant modules in the resonance state;

[0096] The unidirectional body conduction component is located on at least one side of the resonant module, and at least one SOLA fiber cotton layer with a certain thickness. The SOLA fiber cotton itself has a structural space in the shape 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 unidirectional conduction channel for the resonant module to transmit acoustic energy to the conduction surface.

[0097] During operation, the 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 through the unidirectional body conduction component. The vibration frequency and / or amplitude change in a pulsed manner, so that the massage intensity changes in a pulsed manner with the rhythm.

[0098] The SOLA fiber cotton of the SOLA fiber cotton layer is highly elastic upright fiber cotton. It uses highly elastic polyester fibers as raw materials. After being opened by an opener, the polyester fibers with different melting points are evenly distributed by a mixer, and then the cotton web is combed into a fiber web structure by a carding machine. After being adjusted into an interleaved structure by a vertical lapping machine, it is dried and shaped in an oven and cut into a fiber product with an upright structure. The thickness of the SOLA fiber cotton layer used is 0.5 cm - 50 cm.

[0099] Such as Figure 8As shown, when the module 200 is provided with vibration devices 31 and 32, a diaphragm structure 2, a unidirectional body conduction component 1, and a conduction surface 4, wherein the vibration devices 31 and 32 are fixedly attached to the diaphragm structure 2, the diaphragm structure 2 is fixedly attached to the unidirectional body conduction component 1, and the unidirectional body conduction component 1 is fixedly attached to the conduction surface 4, the vibration transmission mode of the above module 200 is that the waves h1 generated by the vibration devices 31 and 32 will be transmitted towards the diaphragm structure 2, and a small amount of waves will be transmitted in the direction away from the diaphragm structure 2. The waves h2 and h3 transmitted to the diaphragm structure 2 will form a standing wave h4. The standing wave h4 is transmitted to the unidirectional body conduction component 1, and the wave h5 formed by the unidirectional body conduction component 1 is unidirectionally transmitted to each point structure on the conduction surface 4. The waves h6 generated by each point structure act on the human body.

[0100] During the above working process, when the vibration structure is a music player, sound waves will be transmitted to the auditory center. On the one hand, taking the human body as a sound field, when the human body is used as a sound field, the transmission path is that the unidirectional body conduction component transmits the sound waves to the human bones, and the human bones directly transmit the sound waves to the auditory center in the cerebral cortex of the thalamus. On the other hand, the space around the seat is used as a sound field, and its transmission path is that the sound waves are transmitted into the auditory center through the human ear with the air medium. The specific order of being transmitted into the auditory center through the human ear is the auricle, external auditory canal, tympanic membrane, malleus, incus, stapes, oval window, perilymph, spiral organ, auditory nerve, and auditory center. In the above two transmission paths, through the above two paths, people can hear stereophonic surround sound. 80% to 95% of the stereophonic surround sound is heard by directly transmitting the sound waves to the auditory center in the cerebral cortex of the thalamus through the human bones, and the remaining 5% to 20% is heard by being transmitted into the auditory center through the human ear.

[0101] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention. Without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
