Description

[Detailed Description of the Invention] [1] The present invention is a vibration type stress M7 like a mansage machine.
t''H position.

[Background technology] As social life has become more complex in recent years, psychological and mental stress such as anxiety, dissatisfaction, anger, and irritation are increasing.
There is a need for self-control means to quickly relieve and release this stress without WJff. The most common methods of stress relief, such as bathing, sleeping, and rest, suppress the sympathetic nervous system and stimulate the parasympathetic nervous system. It is known that it is more effective to give such stimulation to living organisms to a comfortable degree.

However, the vibration-type stress relief devices that have been tried in the United States have either repeated monotonous vibration patterns or repeated slightly complex vibration patterns that change in a certain sequence, so the vibration stimulation can become boring. There was a problem that the stress-relieving effect was weakened.

[Objective of the Invention 1 The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a vibration pattern that is not monotonous, does not have sudden changes, and has moderate fluctuations. To provide a vibration-type stress relieving device that has a sense of anticipation and surprise.

[Disclosure of the Invention 1 The vibration type stress relieving device according to the present invention includes a random signal generation circuit and a filter circuit that receives the random signal as input and has a frequency characteristic such that the amount of transmission is inversely proportional to the frequency. The output waveform of the filter circuit is the vibration pattern of the vibrating body, and the output waveform of the filter circuit is 1/1
A characteristic fluctuation signal is output, and the waveform of this fluctuation signal changes from moment to moment, so biological stimulation vibrations that are always full of expectations and surprises can be obtained.

[Example 1] The main body of the vibration type stress resolving M device of the present invention is a chair 1a as shown in Fig. 1 or a bellows) lb as shown in Fig. It is arranged on the shoulder and waist areas of the bed 1.
In case b, the vibrating body 2 is placed on the back rest, the waist rest, and the chest rest where the calves come into contact.
It can give a pleasant forceful stimulus to the body.

Figure 3 shows the vibration main drive circuit, in which the output signal of the random signal generation circuit 3 is input to the 1/[fluctuation generation filter circuit 4, and the output of the 1/f fluctuation generation filter circuit 4 is used to generate A vibration pattern is generated by a stimulation vibration generation circuit 5, and the vibrating body 2 is driven via a power amplifier 6.

Fig. 5(a) shows the random signal waveform output from the random signal generating circuit 3, Fig. 5(b) shows the power spectrum which is its transfer characteristic, and Fig. 5(a) shows the random signal waveform output from the random signal generating circuit 3, and Fig. 5(b) shows the power spectrum which is the transfer characteristic. This shows the waveform after passing through circuit 4, and shows a so-called 1/f characteristic in which the power spectrum is inversely proportional to the 7-band frequency. This 1/f characteristic is a characteristic of fluctuations commonly seen in wave phenomena in the natural world (sea noise, babbling of streams, etc.).
This is considered to be a pleasant stimulation pattern for living organisms.

Figure 4 shows the specific configuration of the filter circuit for generating 17f fluctuations. Filter A consists of an operational amplifier 01]+vO112, and resistors R3 to R capacitors C1C2.
has a frequency characteristic as shown in FIG. 7(a). That is, the center frequency f0 of filter A is C+
, C2, Rs - R6, and the center frequency f is determined by the value of R5 - R1. A stepped characteristic having a 17f characteristic is determined in the vicinity of . A plurality of filters A, B, C, . . . which have such step-like characteristics and whose center frequencies differ in sequence are connected together to give the overall characteristics as shown in the same figure (d). be. In addition, in Fig. 4, the operational amplification is 30 p.
* + O116 is for converting impedance. Next, a specific example of circuit constants is shown: R,=
IOKΩ, R2=2.7Ω, R3=], OkΩ, R,

= 2.2 μF, C2 = 2.2 μF, and the center frequency “.=
0.48) (2 filters A can be configured.

According to the above configuration, a 1/f fluctuation signal can be obtained from the random signal in real time, and the amplitude and frequency of the biological stimulation vibration are determined based on this fluctuation signal, so a new vibration pattern can always be generated. This is possible.

[Effects of the Invention] As described above, in the present invention, the random signal generation circuit and the 1/f fluctuation generation filter circuit provide a J! It is able to generate iL movement patterns, and the vibration pattern changes moment by moment, allowing it to constantly provide new stimulation with expectations and surprises, so it can relieve tension in the body and at the same time -
It has the effect of helping to relieve stress from a two-mood perspective, and since such fluctuation signals are not obtained by computer calculations, new vibration patterns are always available without being affected by calculation time or memory capacity. It has the advantage that it can be generated endlessly in real time.
