The rotation of the motor 29 is converted into ascending or descending of the rack 37 so that the speaker box 28 can be vertically swung, and the speaker box 28 is tilted in accordance with the tilt angle of the backrest portion 3. The inclination angle of the backrest portion 3 is detected by a change in the resistance value of the variable resistor 16, and is detected as a resistance value, a current value, or a voltage value.
8 is transmitted to the microcomputer of the controller 23, and the microcomputer displays its resistance value, current value,
The number of steps in which the motor 29 rotates is determined according to the voltage value data, and is output to the switchboard 18.

For example, when the inclination angle of the backrest portion 3 is a relatively large angle of 70 degrees or 80 degrees with respect to the horizontal plane, the direction of the speaker box 28 (the direction in which the cone of the speaker 30 vibrates) is the neck portion. The speaker box 28 is tilted slightly upward so as to face a position slightly higher than the airbag 3D.

Further, when the backrest portion 3 has a relatively small inclination angle such as 10 to 20 degrees with respect to the horizontal plane, the orientation of the speaker box 28 (speaker 3
Airbag 3D of the neck is the direction in which the 0 cone vibrates)
Speaker box 2 so that it faces slightly higher
Incline 8 slightly lower.

When the backrest portion 3 has an intermediate inclination angle such as 20 degrees to 70 degrees with respect to the horizontal plane, the speaker box 2 is adapted to the inclination angle.
Incline 8

The inclination angle of the backrest portion 3 is transmitted to the switchboard 18 as a current value or a voltage value flowing through the variable resistor 16, and the interface of the switchboard 18 provides A
The D-converted signal is transmitted to the controller 23, and the controller 23 calculates based on a predetermined calculation formula or compares the tilt angle data corresponding to the current value or the voltage value with the tilt angle data to operate the motor 29. Send to. The switchboard 18 DA-converts the control signal from the controller 23 to drive and control the motor 29.

The switchboard 18 is provided with a plurality of interface circuits for converting the command signal from the controller 23 into an analog signal and converting the variable resistor 16 or other analog data into a digital signal. These interfaces are the controller 23. It is connected to the input / output terminal of. By the control signal from the controller 23, the electric power from the outlet 22 is supplied to the respective connected conductors via the relay circuit, and the control signal or the control signal is supplied.

FIG. 5 shows an example of the operation surface of the controller 23. The controller 23 includes a microcomputer, an interface liquid crystal screen, LEDs, etc. inside, and when the main power button 40 is turned on, the outlet 22 is turned on.
Obtains power from the connected power line.

The controller 23 is provided with an upright direction button 41A and a horizontal direction button 41B for adjusting the inclination angle of the backrest portion 3. The switches of the upright direction button 41A and the horizontal direction button 41B are connected to the microcomputer of the controller 23, and the buttons 41A, 41
Depending on how long B is being pressed, the motor 13
Control the rotation speed of.

For example, when the upright direction button 41A is pressed to erect the backrest portion 3, the motor 13 is rotated in the forward direction for a predetermined time to incline the backrest portion 3 at a predetermined inclination angle. When the 3 is laid down horizontally, the motor 13 is rotated in the opposite direction for a predetermined time to tilt the backrest portion 3 at a predetermined tilt angle.

The inclination angle of the backrest portion 3 becomes the resistance value of the variable resistor 16 and is changed from the switchboard 18 to the variable resistor 16.
Is output as a current value or a voltage value to the microcomputer of the controller 23 from the switchboard 18. The tilt angle detecting means is a variable resistor 16

The motor 128 has its rotation direction and rotation speed controlled by the control signal of the controller 23 described above. The arm 126, the gear mechanism 127, and the motor 128 form a drive mechanism.

The massage chair 120 includes the controller 23 and the switchboard 18 provided in the massage chair 1 of FIG.
Since the control means similar to the above is provided and the drive mechanism such as the motor 128 and the arm 126 is controlled by these control means, the description thereof will be incorporated. Also, this motor 1
The rotation control of 28 is similar to the control of the motor 29 described with reference to FIG.

[0069]

According to the chair of claim 1 of the present invention, the direction of the speaker is changed according to the inclination of the backrest.
The user does not have difficulty listening to music.

According to the chair of claim 2 of the present invention, the speaker is stored so as not to project from the armrest when not listening to music, so that it does not become an obstacle.
