Description

Field of the invention

The present invention relates to a system for generating and transmitting harmonic vibrations, for example generated starting from an audio source, in particular for exerting a massaging action on a human being.
Furthermore, the invention relates also to a method for generating and transmitting the harmonic vibrations generated starting from an audio source, in particular for exerting a massaging action on a human being.

Description of the prior art

As known, several transducers exist that are able to convert the audio waves into harmonic vibrations for different purposes, for example for exerting a massaging action on a person. Normally, for this purpose, the transducer is fixed by screws, bolts, or other fixing elements, to a resonant structure to which the person to be subjected to the aforementioned massage, is arranged in contact, also said vibro-massage, mainly with the purpose to reduce the tension and to produce a relaxing effect on the body and, therefore, on the muscles, the skeletal apparatus, and the internal organs.
An example of such a resonant structure provided with the aforementioned transducer for exerting a vibro-massage on the body of a person is described in EP1827351 .
In this case, the vibro-massage unit comprises a resonant structure, a source of an audio signal arranged to generate an audio signal and a sound transducer which generates vibrations at a frequency and an amplitude modulated on the basis of the audio signal. The transducer is arranged in contact with the resonant structure at a predetermined point in such a way to be able to propagate the vibrations in a differentiated way selectively concentrating the vibrations on the basis of their frequency and their amplitude in determined areas, obtaining in this way a selective distribution of the vibrations.
However, the vibro-massage unit described in EP1827351 provides a resonant structure of static type, therefore its response in terms of propagation of the vibrations and vibrating action produced on the person who is arranged in contact with the same change only if the frequencies of the audio signal emitted by the audio source change.
Other prior art solutions with the aforementioned drawbacks are described in FR2307424 , WO2007/103325 , US2017/173481 , WO01/83024 , EP0488338 and GB2455980 .

Detailed description of some exemplary embodiments of the invention

With reference to the figures 1 and 2, a system 100, according to the invention, for generating and transmitting vibrations, in particular harmonic vibrations, comprises a sound waves source 10 which emits an audio signal at a determined frequency, in particular, a frequency higher than 15-20 Hz, preferably between 20 and 20000 Hz, or more in general an audio signal belonging to a determined range of frequencies, preferably between 20 and 20000 Hz, and a transducer 20, for example a sound transducer, or a tactile transducer, operatively connected to the sound waves source 10 and configured to convert the audio signal coming from the sound waves source 10 into vibrations, in particular harmonic vibrations and/or mechanical vibrations. The system 100 provides, furthermore, a body for propagating vibrations, or a resonant body, through which the harmonic vibrations 5 is propagated, in determined directions. It is, furthermore, provided a transmission device 30 configured to transmit the harmonic vibrations produced by the transducer 20 to the body for propagating vibrations 5. This latter has an elongated geometry and is oriented along a vertical or substantially vertical direction.
As diagrammatically indicated in figures 1 and 2, the propagation body 5 can comprise a tree, preferably a live tree, for example a tree of a public park, or a private garden, but also a structure having the shape of a tree, but of artificial type. More in particular, the tree 5 comprises, in general, a plurality of branches and a trunk 8 oriented along a vertical or substantially vertical direction 105. In other words, the longitudinal axis of the trunk 8 substantially coincides with the aforementioned vertical direction 105. In particular, the tree 5, or other propagation body, comprises a base portion 9, for example the roots, positioned below a ground level 150 of the area where the propagation body 5 is positioned.
In particular, the vibration transmission device 30 can be positioned at the propagation body 5, for example a tree, in a lateral position (see for example the figures 1 and 2) with respect to a sagittal and/or frontal plane, or central or substantially central position, with respect to the same (see for example the figures 4 and 5). The propagation direction of the vibrations involves, however, mainly the trunk 8 of the tree 5 which is crossed by the vibrations from above towards below.
The vibration transmission device 30, for example made of a material chosen among wood, metal, plastic, composite material, comprises a receiving portion 35 integral to the transducer 20 at which the transducer 20 transmits the harmonic vibrations to the transmission device 30, and an engagement portion 40 configured to removably engage the vibration transmission device 30 to the body for propagating vibrations 5 at respective contact surfaces 36 and 6. More precisely, the aforementioned engagement portion 40 is arranged to engage the body for propagating vibrations 5, from above. In particular, in order to cause the engagement portions 40a-40d to move from the rest configuration to the engagement configuration, the aforementioned transmission device 30 is positioned, from above, on the body for propagating vibrations 5.
In this way, the vibrations mainly propagate along the aforementioned vertical direction 105, or substantially vertical, which coincides with the longitudinal axis of the body for propagating vibrations.
More in detail, the harmonic vibrations which are transmitted to the body for propagating vibrations 5 propagate through the same generating a subjective response which is different from a propagation body to another, but that, anyway, involves all the body which is crossed from the above towards below. The modality through which the propagation of vibrations and sound occurs across a body in fact, mainly depends on the structure of the body that, in particular, is linked to the material of which it is made of, and mainly to the density of the same. The system 100 according to the invention allows, therefore, to provide a unique sensorial experience which can be transmitted to one or more people 200, or other living beings, at the same time. More in detail, the sensorial experience can be transmitted to one or more people, or other living beings, 200 that can be directly positioned in contact with the body for propagating vibrations 5 (as diagrammatically shown in figure 4) and through the surface on which the same is positioned, for example the ground (as diagrammatically shown in figure 5). In fact, for example, in case of a tree 5, the harmonic vibrations transmitted to the trunk 8 propagate along a vertical or substantially vertical direction 105, up to reach the roots 9 and from these to the soil where they are located. The or each person 200 who is present in the area where the system 100 is installed will, therefore, receive the harmonic vibrations indirectly from the tree 5 through the soil staying in an erect or seated position, or laying down, and, therefore, not necessarily arranged in direct physical contact with the tree 5. In addition to the above, the propagation of the harmonic vibrations and, advantageously, at least in part of the sound waves diagrammatically shown in the figures with concentric waves 300, occurs through the structure of the tree in such a way that in addition to change from tree to tree, can also be different for the same tree after a certain period of time between an installation and the following because the tree, since it is a living being, is subjected to continuous change of its structure and, therefore, of the mode through which the propagation of the vibrations occurs, and, in case, of the sound through the same. Therefore, the present invention allows to have a tactile and sensorial experience that is always different and, therefore, unique all the times that is experienced by a person or a group of people. Furthermore, the system according to the present invention allows to obtain considerable benefits to the health of the trees on which is installed precisely because of the propagation through their structure of the aforementioned audio waves and harmonic vibrations that exert a revitalizing action on the same and, therefore, on people who experience the aforementioned tactile experience.
As diagrammatically shown, for example in figure 2, the transmission device 30 is provided with at least a first and a second engagement portion 40a and 40b, in the case of figures 2, four engagement portions 40a-40d adapted to move from a rest configuration where they do not engage the propagation body 5, in particular the tree, to an engagement configuration where they engage the propagation body 5, for example at least a branch 7 of the tree, or the trunk 8 of the same, in a removable and, preferably, non-invasive way, in such a way not to cause any trauma to the chosen tree. In all the cases, the body for propagating vibrations coincides with the trunk 8 of the tree 5, which, therefore, is crossed, in any case, by the vibrations along the aforementioned vertical or substantially vertical direction 105.
However, the possibility is also provided that the engagement portions 40 can be present also in a number greater than 4, for example a number comprised between 1 and 10, advantageously between 2 and 10.
In particular, each engagement portion 40a-40d can be an elongated portion having a free end 41a-41d. In this way, the engagement portion 40 is able to engage bodies for propagating vibrations 5 of any shape, in particular having a complex shape. More precisely, the different free ends 41a-41d are adapted to be positioned at different contact zones or portions of the body for propagating vibrations 5, in such a way to transmit the same to a respective portion of the produced harmonic vibrations.
More in particular, during the engagement of the body for propagating vibrations 5 by the plurality of engagement portions 40a-40d, the respective free ends 41a-41d can be adapted to gradually move away from each other.
At the engagement configuration, the receiving portion 35 can be, advantageously, positioned higher than the free ends 41a-41d of the engagement portions 40a-40d.
In particular, the other end 42a-42d of each engagement portion 40a-40d, opposite to the free end 41a-41d, is the one closer to the transducer 20. More in particular, at least two other ends, or second ends, 42a and 42b and/or 42c and 42d of at least 2 engagement portions 40a-40d are connected to each other by a connection portion 43, advantageously in such a way to form said receiving portion 35, to propagate the vibrations produced by the transducer 20 from one to another up to the free ends 41a-41d of the engagement portions 40a-40d. Preferably, the connection portions 43 are arranged in such a way to be superimposed to one another in order to transmit the vibrations produced by the transducer 20 to all the engagement portions 40a-40d.
In the embodiment that is shown from figure 1 to figure 3, four engagement portions 40a-40d are connected to a single connection portion 43, in such a way to form said receiving portion.
In the case of figures 2 and 3, the transmission device 30 is adapted to move from the rest configuration to the engagement configuration by forcing the engagement portions 40a-40d to move away, in particular to elastically move away, from each other. More precisely, as diagrammatically shown in figure 3, once that the force which has, as disclosed above, caused the engagement portions 40a-40d to move away from each other, these tend to go back to the respective starting positions corresponding to the rest configuration, engaging in this way the body for propagating vibrations 5, in particular one or more branches 7 of tree 5.
In the embodiments that are diagrammatically shown in the figures from 7 to 10, the vibration transmission device 30 is provided with a first and at least a second engagement portion 40a and 40b and with at least a clamping member 45, for example a clip, in particular made of metal. More precisely, each clamping member 45 is adapted to reversibly move from a clamped configuration (see figures 7 and 8) where it is adapted to keep the first and second engagement portions 40a and 40b in the engagement configuration, to a disengagement configuration, that is shown in figure 9 for an embodiment of the invention, where it is adapted to allow the first and second engagement portions 40a and 40b to move in the rest configuration in order to allow to remove them.
More in detail, in the embodiments of figures 9 and 10, two couples of engagement portions 40a, 40b and 40'a, 40'b are provided in such a way to allow the vibration transmission device 30 to be anchored at two points of the body for propagating vibrations, in particular the tree 5. In particular, the transducer 20, or the housing body 25 inside of which it is housed, can be mechanically connected to the or each engagement portion 40 and 40' by a link element 37. This can provide a first link arm 38a, advantageously straight, integral to the transducer 20 and/or the housing body 25, and two link arms 38b and 38c which ramify from the first link arm 38a in order to connect this latter respectively to the first and the second connection portion 40 and 40'.
As shown for example in the figures 8, 10 and 12, the device for transmitting vibrations 30, in particular harmonic, or mechanical, vibration, is, furthermore, provided with a housing body 25 configured to house the aforementioned transducer 20. More in particular, the housing body 25 is integral to the transmission device 30. In particular, the housing body 25 is adapted to transmit the harmonic vibrations produced by the transducer 20 to the vibration transmission device 30. Advantageously, the housing body 25 can be provided with a main body provided with an aperture through which the transducer 20 can be introduced into, or extracted from, the main body. Furthermore, the housing body 25 can be provided with a closure, or a lateral wall, adapted to move from an opening position to allow to reach the inside of the aforementioned main body through the aforementioned aperture, and a closing position to avoid that dust, rain, leaves, or other foreign bodies, can reach the transducer 20 compromising the correct operation of the same.
As diagrammatically shown in figure 1, between the sound waves source 10 and the transducer 20 an amplifier 60 can be provided configured to interface the sound waves source 10 with the transducer 20.
According to what is provided by the invention, the sound waves source 10 and the transducer 20 can be operatively connected to each other by a wire connection (see figures 1 and 11), or by respective transmission modules 14 and 24. These can be chosen, for example, among modules for Bluetooth transmission, modules for WI-FI transmission, USB modules, or a combination thereof. More precisely, the sound waves source 10 can be a plant stereo, but also an electronic device, such as a smartphone, a PC, a tablet, a laptop, a device of Echo-dot type, and similar electronic devices, in particular provided with audio card (see figure 6).
As diagrammatically shown in the figures 4 and 5 and in detail in figure 13, according to an embodiment provided by the present invention, the transmission device 30 can provide at least a first and a second transmission portion 31 and 32, each of which having a substantially "U", or substantially "V" shape. More precisely, the first and the second transmission portion 31 and 32 are, advantageously, positioned in such a way to intersect one another, for example by superimposing, as in the case illustrated in the figures 4, 5 and 13, or penetrating one another for a determined depth (case not shown in figure per simplicity) in such a way to define the aforementioned receiving portion 35. At the receiving portion 35, both if it is a crossing or a superimposing portion, or a planar surface, positioned, preferably, substantially at the respective centre lines, the transmission device 30 can provide a link element 37, advantageously a link arm, or pin, adapted to mechanically connect the first and/or the second transmission portion 31 and 32 with the aforementioned housing body 25, or directly with the transducer 20. For example, the link element 37 can be adapted to house in a through or a blind hole provided at least in one, or both, the transmission portions 31 and 32. The at least two transmission portions 31 and 32 can be connected by or more supplementary link elements 39 transversally arranged to each other, or inclined at predetermined angles, with respect to the respective engagement portions 40, in the case of figure 4 the engagement portions 40d and 40b.
As shown, for example, in figure 13 the aforementioned transmission portions 31 and 32 are respectively provided with at least a respective engagement portion 40. In the case of figure 13, both the transmission portion 31 and the transmission portion 32 are, respectively, provided with a first and a second engagement portion 40a, 40b, and 40c, 40d. Generally, the transmission device 30 can be provided with a number n of engagement portions, for example n can be comprised between 1 and 6 and each transmission portion can be provided with a number n' of respective engagement portions 40, with n' comprised between 1 and 6.
Still with reference in particular to the figures 4, 5 and 13, but that, however, can be adopted also for the other embodiments according to the present invention, in an embodiment of the invention, the engagement portions 40a-40d can be fastened to the propagation body 5, for example to one or more branches 7 of the tree, by or more anchoring members 34, such as cables, chains, tapes, in particular elastic tapes, and similar. More in particular, the or each anchoring member 34 is adapted to embrace and clamp between them the or each branch 7 and the or each engagement portion 40, in order to guarantee that the transmission device 30 is kept in the correct installation position.
As diagrammatically shown in the alternative embodiment of figure 14, the system 100, according to the invention, can provide at least a first and a second transducer 20a and 20b, each of which, advantageously, housed in a respective housing body 25a and 25b. Each transducer 20a, 20b can be engaged to a respective branch 7a, 7b, or to the same branch, by a respective transmission device 30a and 30b provided with respective engagement portions 40a and 40b. More in particular, each transmission device 30a and 30b can be provided with a link arm, for example a link arm or pivot adapted to mechanically connect the respective housing body 25a, 25b to the respective engagement portion 40a, 40b.
In the further alternative embodiment provided by the present invention, the transmission device 30 can be provided with at least an engagement portion 40 configured to move from a compacted configuration to an expanded configuration where is adapted to engage the propagation body 5, for example the tree. More precisely, the engagement portion 40 can be adapted to move from the compacted, or minimum lateral encumbrance, configuration, to the expanded configuration causing, for example, by a rotation or a translation, a plurality of engagement portions 47 to rotate about respective hinge points 48. This can, for example, be obtained causing a movable portion 44 to which first ends of the engagement members 47 are fixed, to slide from or towards a fixed portion 49, to which second ends of the engagement members 47 are fixed, along a link bar 46 adapted to directly connect the transducer 20, or the housing body 25 inside of which the same is housed, to the engagement members 47.
This solution is particularly advantageous, in the case that the propagation body 5, in particular the tree, is provided with a cavity. Also this solution is for the propagation body 5, in particular the tree, absolutely non-invasive.
As diagrammatically shown in the further embodiment of the invention of figure 16, the system, according to the invention, for generating and transmitting harmonic vibrations can be also directly applied to a person 200. More precisely, in this case, the body for propagating vibrations 5 is constituted by person 200. More in particular, in this case, each engagement portion, for example four engagement portions 40a-40d are adapted to removably engage, from the above, the vibration transmission device 30 to the person 200 through who, therefore, the vibrations are propagated at respective contact surfaces 36 and 6, along the aforementioned vertical or substantially vertical direction 105, that, in this case, substantially coincides with the longitudinal direction of the person 200.
The foregoing description exemplary embodiments of the invention will so fully reveal the invention according to the conceptual point of view, so that others, by applying current knowledge, will be able to modify and/or adapt for various applications such embodiment without further research and without parting from the invention, and, accordingly, it is therefore to be understood that such adaptations and modifications will have to be considered as equivalent to the specific embodiments. The means and the materials to realize the different functions described herein could have a different nature without, for this reason, departing from the field of the invention. It is to be understood that the phraseology or terminology that is employed herein is for the purpose of description and not of limitation.
