Problems to be solved by the invention

  In the conventional technology, the basic idea of embedding a low-frequency oscillator in a bed or chair was a level of technology. For this reason, no consideration has been given to various problems that occur when a low-frequency oscillator is actually embedded and a human body rides on the bed or chair. In the case of a bed, a person lays down and relaxes the whole body, so if the basic sleep feeling is impaired, even if the low frequency generated by the low frequency oscillator gives a relaxing effect to the human body The impression that the general sleeping comfort is lost. It is a book to solve the problem that the human body can enjoy the relaxing effect of the low frequency oscillator without impairing the sleep feeling that the bed originally expected, which has not been achieved with the conventional low frequency oscillator and the appliance using it. It is an object of the invention.

Tenth, in addition to any one of the first to ninth features, the low-frequency oscillator does not protrude below the lower surface of the free vibration mat in an unweighted state and a use state as a bedding. Features
According to the method of using the body sensation acoustic bed pad of the present invention, the body sensation sound bed pad having any one of the first to tenth features is characterized in that the human body lies on the vibration propagation mat or the body contact sheet thereabove. As a feature,
Twelfth, in addition to the feature of the eleventh body sensation acoustic bed pad, the human body does not touch the low frequency oscillator.

  In the bodily sensation acoustic bed pad of the present invention, in addition to the feature of the bodily sensation acoustic mat 2 provided with the low frequency oscillator 1, the bodily sensation acoustic mat has a two-layer structure of a vibration propagation mat 3 and a free vibration mat 4. In the case where the low-frequency oscillator has the first feature fixed to the vibration propagation mat, a plurality of through holes are provided in the sensory acoustic mat obtained by bonding the vibration propagation mat and the free vibration mat, The low frequency oscillator is installed in the hole. During the installation, the low frequency oscillator is glued and fixed to the vibration propagation mat. By this fixing, most of the vibration generated by the low frequency oscillator is efficiently transmitted to the vibration propagation mat. When the vibration of the low-frequency oscillator moves up and down, the plurality of low-frequency oscillators attached to the sensory acoustic mat all move up and down in synchronization, and the attached vibration propagation mats are the plurality of vibration propagation mats. In response to the up and down movement of the low frequency oscillator, it vibrates up and down.

  In addition to the first feature, in the case of including the second feature in which the body contact sheet 5 is disposed at a position in contact with the vibration propagation mat exposed surface of the sensory sound mat, the vibration propagation mat having excellent vibration propagation characteristics is provided. By installing a body contact sheet having a surface material that the human body feels comfortable on, it is possible to achieve both efficient vibration propagation and comfortable contact with the human body. Here is a detailed description of how the human body feels comfortable. The skin surface of the human body is breathing and sweating. For this reason, an adhesive sheet that closes the skin surface is difficult to breathe and is unhealthy and uncomfortable. Soft materials that are highly breathable and that do not damage the skin when rubbed can be said to be comfortable materials.

  In addition to the second feature, when the body contact sheet has a third feature using quilting as a material, quilting is adopted as a specific material for obtaining air permeability and soft touch. Since the quilting itself is light, the effect of transmitting the vibration of the base vibration propagation mat to the human body with almost no shielding can be expected.

  In addition to any one of the first to third features, a vibration propagation block 6 is inserted in a gap between the low frequency oscillator and the free vibration mat, and the vibration propagation block is in contact with the vibration propagation mat. In the case of having the feature of 4, the vibration propagation block is bonded to the surface of the low frequency oscillator close to the free vibration mat in addition to the direct fixation between the low frequency oscillator and the vibration propagation mat. It is characterized by fixing by a method. Since this vibration propagation block is fixed to the vibration propagation mat, as a result, the low frequency oscillator is fixed to the vibration propagation mat by both direct fixation with the vibration propagation mat and indirect fixation through the vibration propagation block. Thus, the vibration of the low frequency oscillator can be transmitted to the vibration propagation mat more efficiently.

  In addition to any one of the first to fourth features, when the fifth feature of the vibration propagation mat is higher than the hardness of the free vibration mat, as a mat material selection means Use two layers of mats using a simple measure of hardness. The higher the hardness is, the higher the vibration propagation efficiency tends to be. Therefore, the vibration propagation mat uses a highly advanced material, and the free vibration mat used as a role to prevent the vibration of the low-frequency oscillator according to the vibration. Use a low-hardness material that is easy to deform.

In addition to any of the first to fifth features, the density of the vibration propagation mat is 46 kg / m ^{3 to} 48 kg / m ³ and the density of the free vibration mat is 44 kg / m ^{3 to} 46 kg / m. In the case of including the sixth feature of less than m ³ , the vibration propagation efficiency is improved by using a high-density material of 46 kg / m ³ or more for the vibration propagation mat. Considering that the human body is on board, a hard material such as a board is not comfortable to sleep. Therefore, the sleep comfort is set at a density of 48 kg / m ³ or less. On the other hand, the free vibration mat uses a material having a density of less than 46 kg / m ³ so as to be easily deformed in accordance with the vibration so as not to attenuate the vibration of the low frequency oscillator. In order not to sink extremely when a human body gets on, it was decided to be 44 kg / m ³ or more.

  In addition to any of the first to sixth features, in the case where the vibration propagation mat has a seventh feature made of polyester-based solid cotton, the vibration propagation mat has a vibration generated from a low-frequency oscillator. In addition to being able to transmit efficiently to the human body lying on top, the hardness of the polyester-based solid cotton is able to suppress the extreme sinking.

  In addition to any of the first to seventh features, in the case where the free vibration mat has an eighth feature made of polyester-based soft cotton, the vibration of the low-frequency oscillator is attenuated as the free vibration mat. Use a soft polyester-based material with excellent deformation characteristics that will not be allowed to occur. This also prevents the body from sinking due to the weight of the human body.

  In addition to any of the first to eighth features, the low-frequency oscillator does not protrude above the upper surface of the vibration propagation mat in an unweighted state and in a use state as a bedding. In this case, the low-frequency oscillator is installed so that the height of the low-frequency oscillator is lower than the height of the dent that is recessed by compression when a human body lies on the vibration propagation mat. By doing so, even when the human body is on the low-frequency oscillator, the human body does not feel a foreign object. By keeping the upper surface of the low-frequency oscillator from protruding even in an unweighted state, the bed in an unused state is made orderly. For this purpose, the low frequency oscillator is installed such that the upper surface thereof is positioned lower than the upper surface of the vibration propagation mat.

  In addition to any one of the first to ninth features, the tenth feature is such that the low-frequency oscillator does not protrude below the lower surface of the free vibration mat in an unweighted state and a use state as a bedding. When provided, the lower surface of the low-frequency oscillator does not protrude downward even in an unweighted state or in a state where a human body pressure is applied as a bedding. For this purpose, the low frequency oscillator is installed such that the lower surface thereof is positioned higher than the lower surface of the free vibration mat.

  As a method of using the body sensation acoustic bed pad according to the present invention, the body sensation sound bed pad having any one of the first to 10th features has an eleventh feature in which a human body lies on the vibration propagation mat or the body contact sheet thereabove. In the case of providing, the human body lies on the surface of the vibration propagation mat so that the vibration of the low-frequency oscillator is effectively transmitted to the human body.

  In addition to the feature of the eleventh body sensation acoustic bed pad, when the human body has a twelfth feature that does not touch the low-frequency oscillator, the human body does not directly contact the low-frequency oscillator. Thus, the arrangement is devised so that the vibration of the low-frequency oscillator is transmitted to the human body through the vibration propagation mat. As a result, the human body can obtain a pleasant feeling as if it were wrapped in vibration.

Embodiment 1 of the present invention will be described. FIG. 1 shows a first embodiment of the present invention. In the sensory acoustic mat 2 provided with the disk-shaped low frequency oscillator 1, the sensory acoustic mat has a two-layer structure of a vibration propagation mat 3 and a free vibration mat 4, and the low frequency oscillator is fixed to the vibration propagation mat. Has been. This body sensation acoustic mat is used with the human body 100 placed on the vibration propagation mat side as shown in the figure. The mat is used on the bed 101. In this embodiment, a polyester solid cotton having a density of 46.5 kg / m ³ was used as the vibration propagation mat, thereby realizing a mat that was not too hard for the human body and excellent in vibration propagation characteristics. The free vibration mat is made of polyester-based cotton having a density of 44 kg / m ³ so as to maximize the effect of suppressing the vibration attenuation of the low frequency oscillator and the function as a cushion when a human body is put on the mat. It was. It was found that the combination of these two materials is the best combination as a body acoustic mat. Two polyester-based materials are glued to finish a two-layered body acoustic mat. The body sensation acoustic mat has a plurality of through holes. The low frequency oscillator 1 is fitted and glued into the hole. Gluing is performed between the low-frequency oscillator and the vibration propagation mat. By this gluing, the low-frequency oscillator is fixed to the body acoustic mat without falling off, and this vibration can be efficiently propagated to the vibration propagation mat. In FIG. 1, the low-frequency oscillator is in contact with the vibration propagation mat but is not in contact with the free vibration mat. As described above, it is a feature of this embodiment that the low-frequency oscillator contacts only the vibration propagation mat so that the vibration is efficiently propagated to the vibration propagation mat. In FIG. 1, it can be seen that the upper surface of the low frequency oscillator is disposed lower than the upper surface of the vibration propagation mat. This is because even when a human body riding on the vibration propagation mat rolls over and comes to the low frequency oscillator, consideration is given so as not to contact the hard part of the low frequency oscillator. In this case, the upper surface of the low frequency oscillator is arranged 5 mm lower than the upper surface of the vibration propagation mat in an unweighted state. The reason why the lower surface of the low frequency oscillator is arranged higher than the lower surface of the free vibration mat is that the low frequency oscillator does not come into contact with the bed 101 when it oscillates with a human body on it. It is. It is placed 10mm higher. When the low-frequency oscillator comes into contact with the bed 101, vibration is applied to the bed and the surface of the bed is deteriorated and vibration propagation efficiency to the human body is remarkably lowered.

  FIG. 2 is a front view of the body sensation acoustic mat 2 according to the first embodiment. A plurality of low frequency transmitters 1 are embedded in the body sensation acoustic mat.

  FIG. 3 depicts Example 2 of the present invention. In addition to the characteristics of the first embodiment depicted in FIG. 1, a body-sensing acoustic bed pad is characterized in that a body contact sheet 5 is disposed at a position in contact with the vibration propagation mat exposed surface of the body-sensing acoustic mat. Light quilted fabric was used as the body contact sheet. By using a light quilted fabric, it is possible to suppress a decrease in propagation efficiency due to vibration absorption in the fabric, and when the human body rides, the ventilation is good and the feeling of sleep is improved.

  Embodiment 3 of the present invention will be described with reference to FIG. In addition to the features of the second embodiment, the vibration propagation block 6 is provided. This block is arranged so as to surround the surface of the low-frequency oscillator 1 where the vibration propagation mat is not in contact. This block is glued to all of the surrounding low frequency oscillator, vibration propagation mat and free vibration mat. As a result, the low-frequency oscillator is more firmly fixed, and the posture of the oscillator can be always maintained correctly. Therefore, the vibration vectors of a plurality of oscillators are aligned, and vibration can be efficiently propagated to the vibration propagation mat.

  Embodiment 4 of the present invention will be described with reference to FIG. In the sensory acoustic mat 2 in which a plurality of low-frequency oscillators 1 are arranged, the low-frequency transmitter is contacted and fixed to a vibration propagation mat 3 having a thickness of 15 mm, and the upper surface of the low-frequency oscillator is higher than the upper surface of the vibration propagation mat. Is also located 5 mm below. The lower surface of the low-frequency transmitter is disposed 2 mm above the lower surface of the free vibration mat 4 having a thickness of 15 mm. The quilting surface material 7 is positioned above the vibration propagation mat, and a cloth lining 8 is disposed below the free vibration mat. The quilting outer material and the cloth lining are sewn together to form a bag shape. It contains a vibration propagation mat and a free vibration mat fitted with a low-frequency transmitter.
