On the output side of the microcomputer 9, one or both of a DA converter or an IO port that constitutes a part of the control unit 8 and is connected to the above-mentioned motor control circuit 13 is provided as a composite signal output means 17 .

FIG. 3 is a block diagram showing the control structure of the driving unit side of the vibrating device. The rotational power system of the electric motor 14 is converted into a reciprocating motion by a conversion mechanism 18 formed of a crank mechanism or a cam mechanism, and the reciprocating motion is transmitted to the vibrating table 6 to vibrate the vibrating table 6 . That is, the vibrating table 6 vibrates at a predetermined cycle in accordance with the rotation speed of the electric motor 14 .

As shown in FIG. 4 , the cycle (number of vibrations) of the vibration of the vibrating table 6 is determined by the output shaft (not shown) of the electric motor 14 or the crank shaft 19 constituting a part of the crank mechanism, that is, the rotation speed of the sensing object shaft ( Rotation speed) is detected by a rotation sensor (period detection means, speed detection means) 12 such as an encoder.

In step S100, the subroutine of the adjustment processing is executed, and when the subroutine processing 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 ends, the processing returns to step S100.

FIG. 6 is a flowchart showing the processing steps of a subroutine of adjustment processing. When the microcomputer 9 starts the subroutine processing of the adjustment processing, it proceeds to step S101. In step S101, check the flag indicating whether the cycle and phase of the vibration of the vibrating table 6 caused by the electric motor 14 are adjusted corresponding to the cycle and phase of the music extracted by the sound signal. When OFF, the adjustment processing is not yet completed, and the process proceeds to step S102.

This flag is reset to OFF in the initial state. Even if it is set to ON once, it will be reset to again after the time calculated from the interval from the start to the end of playback of a song, etc. elapses. OFF.

When the microcomputer 9 starts the subroutine processing of the vibration control processing, it proceeds to step S201. In step S201, the first signal input from the conversion device 4 is acquired by the first signal input means 16, and the process proceeds to step S202.

In step S202, the microcomputer 9 generates or reads from its own memory to obtain a second signal, which is an electrical signal different from the first signal, and proceeds to step S203. That is, by the process of step S202, the 2nd signal acquisition means which acquires a 2nd signal is comprised.

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

The second signal is generated or read by the microcomputer 9 .

The thus obtained first signal and second signal are synthesized to generate a composite signal. The vibration of the vibrating table 6 is controlled based on the synthesized signal.

It can vibrate according to the second signal, so there will be no gap unnaturally.

By the way, as long as the sound source system can be reproduced by the smartphone 2, various forms can be used.

In addition, the second signal can also be canceled by the dial operator 4a, and at this time, the vibrating table 7 vibrates only according to the first signal. In other words, the dial operator 4a functions as a switching means for switching between a single mode of controlling the electric motor 14 based only on the first signal, and a composite mode of controlling the electric motor 14 with a composite signal.

Incidentally, it is also possible to install a means for switching between the composite mode and the single mode in the control unit 8 . Furthermore, the switching means is used to perform a first signal output mode in which only the first signal is output, a second signal output mode in which only the second signal is output, and when at least one of the first signal and the second signal is output (the amplitude is not 0), the above-mentioned composite mode that outputs the signal, only when both the first signal and the second signal are output (the amplitude is not 0), the switching mode of the AND mode that inputs the signal can also be configured.

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

In addition, as an actuator instead of the electric motor 14, an actuator that operates periodically may be used. For example, a hydraulic motor can be considered. In this case, an electromagnetic proportional control valve (control means) that controls the supply, discharge, and flow rate of the hydraulic motor's hydraulic motor is installed in the synthetic signal instead of the above-mentioned motor control circuit 13. output side of the output circuit 17.

In addition, hydraulic motors and spatial motors that can be controlled by electromagnetic proportional control valves can also be used.

Also, when synthesizing the first signal and the second vibration signal, as shown by the dotted line in Fig. 8, the amplitudes of the two signals may be added.

Furthermore, the part to be vibrated is not limited to the vibrating table 6, and what the user puts on his or her body may be used as the part to be vibrated.

Next, with reference to FIG. 9 , for another embodiment of the present invention, portions different from those described above will be described.

FIG. 9 is a block diagram showing a control structure of a vibrating device related to another embodiment of the present invention. In the form shown in the figure, the control unit 24 constituted by a microcomputer or the like generates or reads and outputs the second signal.

The first signal output from the conversion device 4 is input to a signal synthesis circuit (signal synthesis means) 27 through a first signal input circuit (first signal acquisition means) 26 . On the other hand, the second signal output from the control unit 24 is input to a signal synthesis circuit (signal synthesis means) 27 through a second signal input circuit (second signal acquisition means) 28 .

The signal synthesizing circuit 27 is configured by connecting the first signal input circuit 26 and the second signal input circuit 28 in parallel, and outputting to the aforementioned motor control circuit 13 through the synthesizing signal output circuit 29 .
