Particularly, when the resonance module of the acoustic structure is in an anti-resonance state, the vibration amplitude of the rigid part reaches a minimum value, and the surface where the rigid part is located has a minimum radiation acoustic resistance, so that the sound wave radiation capability of the surface is remarkably reduced. In addition, the working frequency of the resonance module in the embodiment of the present invention is defined as the result that the resonance module can reduce the transmission or suppression of the air noise in the original vibration sound structure (i.e., when the resonance module is not attached), so that the resonance module of the present invention has not only a very strong pulse type vibration effect but also a very good massage effect, the frequency and/or amplitude changes in a pulse type, the change of the massage intensity on the seat also changes in a pulse type, and the vibration of the vibration sound structure and the transmission of the structure noise in the band gap frequency band are effectively suppressed, thereby having a low noise and a very good massage effect.

In this case, the seat surface may be used as a conduction surface, for example, if a seating space is provided in the seat portion to exclusively receive the module 200 therein, or a specific mounting portion is provided for mounting the module 200.

Moreover, in order to facilitate the connection of the conductive connection portion and the diaphragm structure 2, lugs 223 may be disposed on two sides of the conductive connection portion, the lugs 223 may be disposed symmetrically or asymmetrically, corresponding threaded holes are disposed on the lugs 223, and bolts are screwed into the threaded holes on the lugs 223 and the threaded holes on the connection unit 26, so as to fix the diaphragm structure 2 and the left and

31 and 32.

In the present embodiment, the vibration source structure may be configured as the left vibration device 31 and the right vibration device 32, and when controlling the vibration generated by the left vibration device 31 and the right vibration device 32, the left vibration device 31 and the right vibration device 32 may generate the waves with the same vibration frequency and opposite transmission directions, and the superposition of the waves with the same frequency and opposite transmission directions may form a standing wave, which may improve the vibration energy, thereby improving the vibration effect.

If the vibration source structure is designed as a single vibration device, in order to generate the standing wave described above, a reflection plate for reflecting the wave can be mounted in the transmission direction of the wave generated by the single vibration device, wherein the material of the reflection plate can be a metal material or a non-metal material, without limitation, the reflection plate is fixed on the one-way body conduction structure 1, the wave moving to the reflection plate will be reflected to form a reflected wave, the reflected wave and the wave generated by the single vibration device will form the standing wave to act on the one-way body conduction structure 1 because the frequency is the same and the propagation direction is opposite, the propagation speed of the standing wave is fast, and the generated vibration effect is excellent.

In a specific application, the second diaphragm structure and the first diaphragm structure may be the same structure, and the attachment fixing portion and the vibration source structure are generally rigidly connected in a manner including, but not limited to, high-strength glue, riveting, and bolt-nut fixing. In this example, the bolts 222 are fixed to the diaphragm through a plurality of holes 221 provided in the diaphragm and bolt holes provided in a connection end 223 of a connection cover of the vibration device, thereby fixing the vibration source structure to the diaphragm.

During operation, the vibration of the left/

right vibration devices

31, 32 drives the vibration of the bonding fixing part, and then the vibration of each sub-diaphragm 24 is linked.

When the sub-diaphragms 24 of the resonant modules are attached to the surface of the vibration source, the surface of the vibration source is considered as a piston-type vibration unit discretized by each resonant module of the acoustic structure. On one hand, the plurality of resonant subunits can generate a band gap effect based on a local resonance principle and a band gap effect based on a Bragg scattering principle brought by the spatial periodicity of the plurality of resonant subunits, so that the vibration of the vibration sound structure in a band gap frequency band and the transmission of structure noise are effectively inhibited. On the other hand, the piston type vibration unit and the acoustic structure resonance module arranged on the piston type vibration unit form a basic-spring-vibrator acoustic system, namely the piston type vibration unit is used as a base, the elastic part of the acoustic structure resonance module is a spring (containing certain damping), and the rigid part of the acoustic structure resonance module is a vibrator. After crossing the resonance frequency of the acoustic system, the vibration amplitude of the vibrator is initially smaller than the vibration amplitude of the base, and the vibrator has a larger proportional area enough to cover the base surface with a larger area, so that the base acoustic radiation is smaller through the surface where the protons are located. Particularly, when the resonance unit element of the acoustic structure is in an anti-resonance state, the vibration amplitude of the rigid part reaches a minimum value, and the surface where the rigid part is located has a minimum radiation acoustic resistance, so that the sound wave radiation capability of the surface is obviously reduced. In addition, the working frequency of the resonance module in the embodiment of the invention is defined as that the resonance module can reduce the transmission or suppression result of the air noise in the original vibration sound structure (namely when the resonance module is not attached), so that the resonance module of the embodiment not only has extremely strong pulse type vibration effect to achieve excellent massage effect, but also the frequency and/or amplitude are generally changed in a pulse mode, so that the massage intensity on the seat can be changed in a pulse mode along with the rhythm of music of a user, and the vibration of the vibration sound structure and the transmission of the structure noise in a band gap frequency band are effectively suppressed, thereby having the effect of small noise and excellent massage effect.

The shape of the sub-diaphragm 24 may be curved with the opening facing downward, or the sub-diaphragm 24 may be curved with the opening facing upward, generally, depending primarily on the direction of conduction to be provided or the direction in which enhancement is desired.

The diaphragm structure in fig. 5 may have a trapezoidal shape, and the sub-diaphragms may also have a corrugated shape, the corrugated shape is to simulate the form of sound wave transmission in water, the sound wave transmission speed is high, and the loss of vibration energy in the transmission process is reduced.

In some embodiments of the present invention, the second diaphragm structure 22 is the same as the first diaphragm structure 21, and a different structure may be selected. In some embodiments of the present invention, the second diaphragm structure 22 is connected to the first diaphragm structure 21, or can be disconnected and set as an independent structure, and similarly, the first diaphragm structure 21/the second diaphragm structure 22 can be a vertically symmetrical structure or a vertically asymmetrical structure.

accommodating grooves

61 and 62 adapted to the vibrator are arranged in the supporting body 6, and the diaphragm structure 2 is arranged on the supporting body 6.

Typically, the support body 6 will be configured to conform to the curvature of the human body, and the curvature of the membrane structure will conform thereto. It is understood that the membrane structure may be a planar sheet or a three-dimensional layer, or may be curved, and may be modified adaptively according to the installation position and the body structure to be serviced.

In the invention, a unidirectional conductive cotton layer is arranged between the membrane structure and the seat body, and in the embodiment, the unidirectional conductive cotton layer is generally made of SOLA fiber cotton layer.

For example, 100% of high-elasticity polyester fiber is used as a raw material, the melting point of the high-elasticity polyester fiber is 160-220 ℃, the denier number is 1.1-7D, after opening cotton by an opener, the high-elasticity polyester fiber with different melting points is uniformly distributed by a stirrer, a cotton net is carded into a fiber net structure by a carding machine, the fiber net is adjusted into a staggered structure by a vertical lapping machine, and then the fiber net is dried and shaped by an oven at about 180 ℃ and cut into a vertical structure, so that high-elasticity vertical cellucotton cotton is formed, and the high-elasticity vertical cellucotton cotton product is cut into slices with regular thickness. Or, 100% high-elasticity polyester fiber is used as a raw material, the melting point of the high-elasticity polyester fiber is 160-220 ℃, the denier is 1.1-7D, after cotton is opened by an opener, the high-elasticity polyester fiber with different melting points is uniformly distributed by a stirrer, a cotton net is carded into a fiber net structure by a carding machine, the fiber net is adjusted into a staggered structure by a vertical lapping machine, and then the fiber net is dried and shaped by an oven at about 200 ℃ and cut into a vertical structure, namely high-elasticity vertical cellucotton cotton is formed, and a high-elasticity vertical cellucotton cotton product is cut into slices with regular thickness.

The SOLA cellucotton has a structural space which is in an upright fibrous shape, and the upright fibers are arranged in the same direction as the acoustic energy transmission direction, so that the upright fibrous structure of the SOLA cellucotton layer forms a unidirectional conduction channel for transmitting the acoustic energy to the seat body through the resonance module. The SOLA fiber wool may be a thick layer as shown in fig. 2, noting that the direction of the standing fibers inside the SOLA fiber wool should coincide with the direction of sound or vibration propagation when set. There may be multiple propagation channels formed by multiple upstanding fibers within the SOLA cellucotton. It should also be noted that a unidirectional conductive path is merely a path in the logical sense, in the simple sense that sound or vibration propagation coincides with the direction of the fibers, thus forming a so-called unidirectional conductive path that carries acoustic energy.

The mode can ensure that the one-way conductivity of the acoustic energy transmitted to the seat body by the resonance module has extremely strong conductivity, namely the conductivity of the one-way channel, and the transmission of the sound on the rest directions can be blocked, namely, the one-way conduction channel from the vibrator to the diaphragm and from the diaphragm to the SOLA cellucotton is formed on the seat body to form a good acoustic energy transmission channel, and the rest directions basically have no sound transmission, namely, a certain effect of blocking the transmission of the sound to the rest directions is achieved.

In some embodiments of the invention, a damping layer may be included at the opposite end of the SOLA fiber cotton layer from the vibration source or sound source to block the transmission of vibrations generated by the vibration source structure away from the chair proximate the user's seat, resulting in a better acoustic energy conduction path.

It will be appreciated that the SOLA cellucotton may be disposed between the seat body and the resonant module, or below the vibration source of the resonant module. For example, when the module is arranged below the vibration source, the SOLA cellucotton can also achieve the effect of one-way transmission, for example, when the module is arranged on a seat independently, the SOLA cellucotton is transmitted to the surface layer of the seat through the lower part, then the SOLA cellucotton is transmitted to each tiny part of the body through the surface layer as a medium, and the SOLA cellucotton can also be transmitted to each tiny part of the body to form resonance with water in the body.
