In addition to the conversion device 4, two sensors 11 and 12, which will be described later, are connected to the input side of the control unit 8. On the other hand, an electric motor (actuator) 14 is connected to the output side of the control unit 8 via a motor control circuit (control means) 13.

The conversion device 4 receives a sound signal converted into sound when an earphone, a speaker, or the like is used from the receiving device 3, and the received sound signal is an electric signal (more specifically, a voltage signal) suitable for vibration control. Is converted into a first signal, and this first signal is input to the control unit 8.

Further, the conversion device 4 is provided with a dial operation tool (switching means) 4a that increases / decreases the amplitude (voltage value) of the first signal to be output between 0 and a predetermined value.

On the input side of the microcomputer 9, an AD converter or IO port that constitutes a part of the control unit 8 and to which the above-mentioned conversion device 4 is connected is provided as a first signal input means (first signal acquisition means) 16. There is.

The electric motor 14 may be a normal DC motor or a stepping motor. The motor control circuit 13 is composed of an FET circuit, a switching circuit, or the like, and controls on / off and rotation speed (rotational speed) of driving the electric motor 14.

On the output side of the microcomputer 9, one or both of the DA converter and the IO port, which form a part of the control unit 8 and to which the motor control circuit 13 described above is connected, are provided as the combined signal output means 17.

FIG. 3 is a block diagram showing a control configuration on the drive unit side of the vibration device. The rotational power of the electric motor 14 is converted into reciprocating motion by a conversion mechanism 18 including a crank mechanism or a cam mechanism, and this reciprocating motion is transmitted to the shaking table 6 to vibrate the shaking table 6. That is, the shaking table 6 vibrates at a predetermined cycle according to the rotation speed of the electric motor 14.

As shown in FIG. 4, the vibration cycle (frequency) of the shaking table 6 is the rotation speed (rotational speed) of the sensing target shaft, which is the output shaft (not shown) or the crank shaft 19 constituting a part of the crank mechanism of the electric motor 14. It is detected by a rotation sensor (period detection means, speed detection means) 12 such as an encoder that detects (speed). The rotation sensor 12 is one of the above-mentioned sensors connected to the input side of the control unit 8.

FIG. 5 is a flow chart showing the processing contents of the microcomputer. When the power is turned on, the microcomputer 9 proceeds to step S100. In step S100, the subroutine of the adjustment process is executed, and when the subroutine process is completed, the process proceeds to step S200. In step S200, the subroutine processing of the vibration control processing is executed, and when the subroutine processing is completed, the processing is returned to step S100.

FIG. 6 is a flow chart showing a processing procedure of a subroutine of adjustment processing. When the processing of the subroutine of the adjustment processing is started, the microcomputer 9 proceeds to step S101. In step S101, a flag indicating whether or not the process of adjusting the period and phase of the vibration of the shaking table 6 by the electric motor 14 corresponding to the period and phase of the rhythm of the music extracted by the sound signal is checked is checked. , OFF, it is assumed that this adjustment process has not been completed yet, and the process proceeds to step S102.

This flag is reset to OFF in the initial state, and even if it is set to ON once, it will be reset to OFF again when the time calculated from the interval from the start to the end of the playback of one song elapses. Will be reset.

In step S102, a process of extracting the rhythm of the sound signal (music) that is the source of the first signal is performed based on the first signal input from the conversion device 4, and the process proceeds to step S103. That is, the process of step S103 constitutes a rhythm extraction means for extracting the rhythm of the sound signal.

In step S103, the rotation cycle and phase of the electric motor 14 (the vibration cycle and phase of the shaking table 6) are detected by the passing sensor 11 and the rotation sensor 12, and the process proceeds to step S104.

In step S104, it is confirmed whether or not the detected rotation cycle of the electric motor 14 and the cycle of the rhythm of the extracted sound signal are synchronized and the phases of the two are in agreement, and the cycles of both are set. If they are synchronized and the phases match, the process proceeds to step S106, and if not, the process proceeds to step S105.

In step S105, the rotation speed of the electric motor 14 is controlled so that the cycles of the two are matched and the phases are matched (matched), and this subroutine process is terminated. On the other hand, in step S106, the flag is set to ON and this subroutine processing is terminated.

By the way, even if the cycles of the two are synchronized and the phases do not match by one subroutine process, the cycle and phase are gradually repeated by repeating the processes of step S101 → step S102 → step S103 → step S104 → step S105. Approaches the target value.

If the flag is ON in step S101, this subroutine process is terminated.

In step S202, the microcomputer 9 acquires a second signal, which is an electric signal different from the first signal, or reads it from its own storage unit or the like, and proceeds to step S203. That is, the second signal acquisition means for acquiring the second signal is configured by the process of step S202.

Incidentally, the second signal is a signal having periodicity, and the period and the phase may be matched with the first signal, or one or both of the period and the phase may be set to be different.

In step S203, the first signal and the second signal are combined, and the process proceeds to step S204. That is, this step S203 constitutes a signal synthesis means for synthesizing the first signal and the second signal.

In step S204, the combined signal, which is the electric signal synthesized in step S203, is output to the electric motor 14 by the combined signal output means 17 via the motor control circuit 13, and the shaking table 6 is vibrated, and this subroutine processing is performed. To end.

FIG. 8 is an explanatory diagram illustrating an example of the processing shown in FIGS. 5 to 7. As shown in the figure, the conversion device 4 extracts a portion having an amplitude equal to or higher than a predetermined value from the sound signal, and executes conversion to the first signal based on the extracted component. The second signal is generated or read by the microcomputer 9.

The first signal and the second signal acquired in this way are combined to generate a combined signal. The vibration of the shaking table 6 is controlled based on this combined signal.

According to the vibrating device configured as described above, the vibrating table 6 vibrates according to the rhythm of the music played by the smartphone 2, so that the user can enjoy exercising, but there is no lyrics. Even during the interlude, the shaking table 6 vibrates based on the second signal, so that there is no unnatural gap.

Incidentally, the sound source can use various formats as long as it can be reproduced by the smartphone 2.

Further, it is also possible to cancel the second signal by the dial operation tool 4a, and in this case, the shaking table 7 is vibrated only by the first signal. In other words, the dial operating tool 4a functions as a switching means for switching between a single mode in which the electric motor 14 is controlled only by the first signal and a combined mode in which the electric motor 14 is controlled by the combined signal.

Incidentally, the control unit 8 may be provided with means for switching between the composite mode and the single mode. Further, when the switching means has an output in at least one of a first signal output mode that outputs only the first signal, a second signal output mode that outputs only the second signal, and the first signal and the second signal. In the case of (amplitude is not 0), the above-mentioned composite mode that outputs the signal and AND that outputs the signal only when both the first signal and the second signal have outputs (amplitude is not 0). It may be configured to switch to the mode.

When a stepping motor is used as the electric motor 14, the rotation sensor 12 and the passage sensor 11 can be omitted.

Further, as an actuator instead of the electric motor 14, an actuator that operates with periodicity may be used. For example, a hydraulic motor or the like can be considered. In this case, an electromagnetic proportional control valve (control means) for controlling the supply / discharge and flow rate of hydraulic oil to the hydraulic motor is used instead of the above-mentioned motor control circuit 13. It is provided on the output side of the combined signal output means 17.

In addition to this, it is also possible to use a hydraulic motor or a spatial motor that can be controlled by an electromagnetic proportional control valve.

Further, when synthesizing the first signal and the second signal, the amplitudes of both signals may be added as shown by the virtual line in FIG.

Further, the target portion to be vibrated is not limited to the shaking table 6, and a person worn by the user may be the target portion of vibration.

Next, with reference to FIG. 9, a portion different from the above-described embodiment of the present invention will be described.
