Abstract

There is provided a signal control device including a signal output unit configured to output a signal for a vibratory device, and a signal control unit configured to control the signal. Between a case where a change from a reference level to a first level is exerted on the signal and a case where a change from the first level to the reference level is exerted on the signal, magnitudes of variation amounts of acceleration per unit time generated in the vibratory device are different from each other. The signal control unit exerts the change from the reference level to the first level and the change from the first level to the reference level on the signal.

Claims

1. A signal control device comprising:

A signal output unit configured to output a signal for a vibratory device; and

a signal control unit configured to control the signal,

wherein between a case where a change from a reference level to a first level is exerted on the signal and a case where a change from the first level to the reference level is exerted on the signal, magnitudes of variation amounts of acceleration per unit time generated in the vibratory device are different from each other, and

wherein the signal control unit exerts the change from the reference level to the first level and the change from the first level to the reference level on the signal.

2. The signal control device according to claim 1,

wherein between a case where a change from the reference level to a second level is exerted on the signal and a case where a change from the second level to the reference level is exerted on the signal, a magnitudes of variation amounts of acceleration per unit time generated in the vibratory device are different from each other, and

wherein the signal control unit exerts the change from the reference level to the second level and the change from the second level to the reference level on the signal.

3. The signal control device according to claim 2,

wherein one of the first level and the second level has a positive value and the other one of the first level and the second level has a negative value.

4. The signal control device according to claim 2,

wherein the first level and the second level are different from each other in the magnitude.

5. The signal control device according to claim 2,

wherein the first level and the second level are different from each other in a duty ratio.

6. The signal control device according to claim 1,

wherein the signal control unit determines, on the basis of predetermined data, whether to exert the change from the reference level to the first level and the change from the first level to the reference level on the signal.

7. The signal control device according to claim 6,

wherein the signal control unit determines, on the basis of predetermined data, whether to exert the change from the reference level to the first level and the change from the first level to the reference level on the signal, or the change from the reference level to a second level and the change from the second level to the reference level are exerted on the signal.

8. A signal control system comprising:

a vibratory device; and

a signal control device,

wherein the signal control device includes

a signal output unit configured to output a signal for the vibratory device, and

a signal control unit configured to control the signal,

wherein the signal control unit exerts a change from a reference level to a first level and a change from the first level to the reference level on the signal, and

wherein between a case where the change from the reference level to the first level is exerted on the signal and a case where the change from the first level to the reference level is exerted on the signal, magnitudes of variation amounts of acceleration per unit time generated in the vibratory device are different from each other.
