Description

[Detailed Description of the Invention] [Technical Field] The present invention provides a vibrating body disposed in the back and lumbar parts of a main body that has a part that comes into contact with the user's back and lumbar region, such as a chair or bed. The present invention relates to a stress relief device.

[Background technology] In recent years, as social life has become more complex, psychological and mental stress such as anxiety, dissatisfaction, anger, and irritability has increased, and there is a need for a means to quickly resolve or release this stress without accumulating it. It has become necessary to take measures. One method for relieving stress is a static stress relieving method that suppresses the sympathetic nervous system and stimulates the parasympathetic nervous system, as typified by bathing, sleeping, and resting. In static stress relief methods, removing stimuli completely or applying specific stimuli such as vibration, heat, hearing, and vision to a comfortable level to the body helps relieve stress. However, in the past, this type of vibration-type stress relief device applied vibration stimulation with either a monotonous vibration pattern or a vibration pattern that changed in a preset sequence. The problem was that I got stuck in a rut and couldn't get an effective stress relief effect.

[Objective of the Invention] The present invention has been made in view of the above points, and its object is to provide a vibration pattern that is not monotonous, has moderate fluctuations, and does not involve sudden changes. Moreover, it is a stress relief device that can provide vibration stimulation with expectations and surprises, and can provide excellent stress relief effects that cannot be obtained by changing the vibration pattern based on a monotonous vibration pattern or a preset sequence. Our goal is to provide the following.

[Disclosure of the Invention] Embodiment 1 FIGS. 1 to 5 show an embodiment of the present invention, in which the main body 1 on which the vibrating body 2 is arranged is a chair 1a as shown in FIG. 1, or a chair 1a as shown in FIG. bed 1b like
In the case of the chair 1a, the vibrating body 2 is connected to the backrest 12 which is the upper part of the backrest 11 and the backrest 1.
A plurality of vibrating bodies 2 are provided at the lower part of the chair 1, which is the lower part of the seat 13, and by sitting on the chair 1a, one can obtain mentally and physically comfortable vibrations. A plurality of back rest parts 14 are provided on which the upper part of the back rests, waist rest parts 15 are brought into contact with the lower part of the back, and leg rest parts 16 are provided with the vicinity of the calves. It is now possible to obtain physically comfortable vibrations.
The vibrating body 2 is driven by a driving circuit with a vibration pattern based on wave phenomena in the natural world.

Figure 3 is a schematic diagram of the vibration pattern.
Figure a is a schematic representation of the vibration amplitude and vibration frequency that can be varied continuously (the diameter of the circle corresponds to the vibration amplitude, and the area of the diagonal line corresponds to the frequency), and pattern A in figure b is a schematic representation of the vibration amplitude and vibration frequency that can be varied continuously (the diameter of the circle corresponds to the vibration amplitude, and the area of the diagonal line corresponds to the frequency). Pattern B is a vibration pattern in which the four (4) vibrating bodies 2 vibrate with the same amplitude and the same frequency, and pattern B is a vibration pattern in which the left and right pairs of vibrating bodies 2 vibrate with different amplitudes and different frequencies. . Furthermore, pattern C is a vibration pattern in which the upper and lower vibrating bodies 2 vibrate with different amplitudes and different frequencies, and pattern D is a vibration pattern in which each vibrating body 2 vibrates with different amplitudes and different frequencies. It is. It is possible to freely create such vibration patterns, and by appropriately changing these vibration patterns over time (changes based on wave phenomena in the natural world), it is possible to create comfortable vibrations that can relax the mind and body. This will allow you to create patterns.

Figure 4 shows the first specific example. Wave phenomena in the natural world include fluctuations in the intensity of sea noise as shown in A in Figure a, and changes in the intensity of wind as shown in Figure A in B. For example, by using wind speed fluctuations (wind breath), etc.
The vibrating body 2 is driven with vibration patterns A and B as shown in FIG. In addition, as wave phenomena in the natural world, fluctuations such as the sound of a babbling stream, the sound of trees in the wind, or other pleasant wave phenomena such as pressure and light can be used. It goes without saying that the vibration pattern may be set based on music composed based on the music. In this way, by changing the vibration pattern of the vibrating body 2 over time based on wave phenomena in the natural world, the vibration pattern is not monotonous, does not involve sudden changes, has appropriate fluctuations, and has a predictable behavior. , it is possible to apply a vibration stimulus having unexpectedness, etc., and an excellent stress relieving effect that cannot be obtained by changing the vibration pattern based on a monotonous vibration pattern or a preset sequence can be obtained.

Figure 5 shows another specific example, based on a wave phenomenon in which the power spectrum has a 1/f type spectrum inversely proportional to the Fourier frequency, as shown in figure a, and as shown in figure b. By setting the frequency and amplitude of the vibration pattern, comfortable vibration stimulation is provided.

It is composed of an amplitude and frequency modulation circuit 37 consisting of a circuit and a frequency conversion circuit, and a drive output circuit 38 which receives the output of the amplitude and frequency modulation circuit 37 and forms a vibrating body drive signal for driving the vibrating body 2. However, the extraction means for extracting the basic signal for setting the vibration pattern from the signal recorded in the recording means is the counter circuit 34 and the D/A conversion circuit 3.

A sound signal such as the sound of a babbling stream is as shown in FIG. 7a, and contains various frequency components. This sound signal is amplified and pulsed by the pulse amplification circuit 33, and a pulse signal as shown in FIG. 7b is obtained. This pulse signal is input to the counter circuit 34, and the number of pulses, that is, the frequency of the wave phenomenon is counted at each sampling interval set by the sampling interval setting circuit 36. The digital signal outputted from the counter circuit 34 is converted into an analog signal by the D/A conversion circuit 35 to obtain a basic signal as shown in FIG. 7c.
