[Detailed Description of the Invention] [Technical Field] The present invention relates to a chair or a bed, which is provided with a back rest portion and a waist rest portion of a main body having a portion that comes into contact with the user's back and one lumbar region. The present invention relates to a stress relieving device that includes a vibrating body and a sound signal generating device that drives a speaker disposed at an audible position on the main body.

[Background technology] In recent years, in social life that has become more complex, anxiety, dissatisfaction, anger,
Psychological and mental stress is increasing due to irritability, and it has become necessary to take measures to quickly eliminate or release this stress without accumulating it. One way to relieve stress is by taking a bath! There are static stress relief methods, such as sleep and rest, that suppress the sympathetic nervous system and stimulate the parasympathetic nervous system. Static stress relief method: 1 Tsuchiyama + 1fi to Uyu 1ii1
Giving the living body specific stimuli such as vibration, heat, hearing, and vision to a comfortable degree helps relieve stress. In the present invention, a method of applying auditory stimulation and vibration stimulation among static stress relieving methods is used, and by using a vibration type that has not been seen before, comfortable vibrations that match the user's preferences are used to improve mental and physical health. It relieves stress.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its purpose is to provide the user with auditory stimulation by allowing the user to select a vibration format according to his/her preference. At the same time,
To provide a stress relieving device capable of applying vibrational stimulation to the body that is in harmony with auditory stimulation.

[Disclosure of the Invention] (Embodiment 1) FIGS. 1 to 4 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. In the case of a bed 1b and a chair 1a as shown in FIG. 3, a plurality of vibrating bodies 2 are arranged in a backrest part 12, which is the upper part of the backrest 11, and a lumbar rest part 13, which is the lower part of the backrest 11, respectively. By sitting on the chair 1a, it is possible to obtain vibrations that are mentally and physically comfortable.In the case of the bed 1b, the vibrating body 2 has a backrest 14 on which the upper part of the back comes into contact, and a waist part on which the lower part of the back comes into contact. Winning part 1
5, and a chest part 16 that comes into contact with the vicinity of the calf.
A plurality of these vibrations are installed in the bed 1b, and by lying down on the bed 1b, you can receive vibrations that are both mentally and physically comfortable.

The vibrating body 2 is driven by a circuit as shown in FIG.

The sound signal generator 31 is a device that generates sound output from a cassette player, a record player, etc., and is connected to a speaker 32 that makes a sound based on the output of the sound signal generator 31. It is arranged on the main body 1 at an audible position. This sound signal generator 31
The device is designed to output a sound signal that relieves mental stress like music, allowing the user to relax through auditory stimulation. On the other hand, the output of the sound signal generator 31 is input to a sound intensity output circuit 35 consisting of a DC cut filter 33 and a detection circuit 34, and this sound intensity output circuit 35 is connected to the sound signal generator r! The sound intensity is extracted from the audible frequency signal output from t31 and output. That is, in the sound intensity output circuit, as shown in the specific circuit diagram of FIG. A detection circuit 34 to which the output of the DC cut filter 33 is inputted performs envelope line detection on the output of the DC cut filter 33 to extract only the amplitude component.

The output of the detection circuit 34, which is the output of the sound intensity output circuit 35, is input to an amplitude level adjustment circuit 36.

This amplitude level adjustment circuit 36 includes a pair of operational amplifiers op,
, op, are connected in series, and each operational amplifier op,.

oP2 is a variable resistor VR for gain adjustment, respectively.

VH2 is provided, and this variable resistor V Rl-
The output value of the line 36 can be varied.

The vibration modulation circuit 40 includes an amplitude modulation circuit 37 and a drive output circuit 39, and includes a reference oscillation circuit 38 that selectively outputs one low frequency of several tens to hundreds of Hz as a reference frequency. The output is amplitude-modulated by the output of the amplitude level adjustment circuit 36, and the vibrating body 2 is driven by the modulated output. Here, the amplitude modulation circuit 37 is constituted by a so-called voltage-controlled operational amplifier OP3, and is configured so that the amplification factor of the signal input to the terminal changes depending on the control voltage input to the terminal ■, which is the voltage control terminal. It has become. That is, since the output of the reference oscillation circuit 38 is input to the terminal ■, and the output of the amplitude level adjustment circuit 36 is input to the terminal ■, the output of the reference oscillation circuit 38 is at amplitude level 1.
The amplitude is modulated by the output of the 11 circuit 36.

The modulated output of this amplitude modulation circuit 37 is input to a drive output circuit 39, and the vibrating body 2 is driven by the modulated output.

The operation will be explained below based on FIG. No. a-d
shall correspond to First, as shown in FIG. 5(a), the output of the sound signal generator 31 includes various frequency components, and the amplitude thereof also changes with time. When this signal is input to the sound intensity output circuit 35, only the amplitude component along the envelope of the signal is extracted, as shown in FIG. 5(b). On the other hand, as shown in FIG. 5(c), the reference oscillation circuit 38 outputs a low frequency wave of a constant frequency, as shown in FIG.
As shown in d), this low frequency is amplitude-modulated by the amplitude modulation circuit 37 based on the output of the sound intensity output circuit 35. In other words, the output of the amplitude modulation circuit 37 is an electric vibration of a constant frequency with an amplitude corresponding to the amplitude of the output of the sound signal generator 31.

By inputting this electric vibration to the vibrating body 2 through the drive output circuit 39, the vibrating body 2 generates vibrations corresponding to the output of the sound signal generating device 31. Generally, since the sound signal generator 31 outputs music, the user will be stimulated by vibrations that match the music while listening to the music, providing pleasant stimulation to both body and mind and relieving stress. . Furthermore, according to the present invention, since the strength of the vibration of the vibrating body 2 can be adjusted by the amplitude level adjustment circuit 36, the user can adjust the vibration strength while listening to music to the strength that feels most in harmony with the music. By making adjustments to achieve this, it is possible to provide the most comfortable stimulation to the mind and body, and the synergistic effect of harmonious vibrational stimulation can further relieve stress.

By adjusting the variable resistors VR, ~VR, so as to obtain vibrations of intensity and frequency that are most in harmony with the music emitted from the speaker 32, stimulation that is felt to be most pleasant to the mind and body can be produced. It has become easier to relieve stress. Note that the other configurations and operations are completely the same as in the first embodiment, so their explanations will be omitted.
