FIG. 2 is a plan view of the notebook PC of the present embodiment. FIG. 3 is a cross-sectional view of the notebook PC of the present embodiment. Note that the monitor unit 45 is not shown in FIGS. 2 and 3.

As shown in FIGS. 1 to 3, the notebook PC 41 of the present embodiment includes a main body unit 44 and a monitor unit 45. The main body 44 includes a tactile device 1, a touch pad 42, a keyboard 43, a CPU (not shown), a memory (not shown), and the like. The notebook PC 41 is a specific example of the "electronic device" in the present invention. The touch pad 42 is a specific example of the "object" in the present invention.

<Touchpad 42>
The touch pad 42 is a device that the operator touches and operates. Specifically, the touch pad 42 is, for example, a flat plate-shaped sensor, and accepts operations performed by a user's finger, specifically, a drag operation and a drop operation. The main body 44 processes the mouse pointer and the like based on the operation received by the touch pad 42, and outputs a vibration generation command to the tactile device 1. Specifically, for example, when the touch pad 42 accepts a drag operation and a drop operation by the user, the main body 44 outputs a latch lock vibration generation command to the tactile device 1. Here, the latch lock vibration generation command is a vibration generation command that generates vibration close to the vibration felt when opening and closing the latch lock, that is, latch lock vibration. The touch pad 42 is a specific example of the "reception unit" in the present invention.

<Tactile device 1>
FIG. 4 is a diagram showing a configuration of a tactile device of the present embodiment. As shown in FIG. 4, the tactile device 1 includes a vibration generating unit 21, a control unit 22, and a counter 23. As shown in FIGS. 1 to 4, the tactile device 1 is attached to the touch pad 42. In the present embodiment, the tactile device 1 is attached to the surface of the touch pad 42 opposite to the flat sensor surface operated by the user. The tactile device 1 is a specific example of the "vibration generator" in the present invention.

<Counter 23>
The counter 23 counts clock pulses generated by, for example, an oscillation circuit using a crystal oscillator, and holds the counted values. This count value indicates, for example, the current time.

<Vibration generator 21>
The vibration generating unit 21 generates vibration based on the drive signal. Specifically, the vibration generating unit 21 is an actuator including, for example, a coil, a permanent magnet, a weight, and the like. The vibration generating unit 21 receives a drive signal from the control unit 22 and vibrates the weight according to the received drive signal. The vibration generating unit 21 and the touch pad 42 are in physical contact with each other, for example, and the vibration generated in the vibration generating unit 21 is transmitted to the touch pad 42.

<Control unit 22>
FIG. 5 is a diagram showing an example of a time change and a vibration waveform of each signal in the tactile device of the present embodiment. FIG. 6 is a diagram schematically showing a time change of each signal in the tactile device of the present embodiment. In FIGS. 5 and 6, the vertical axis represents voltage and the horizontal axis represents time. The vibration waveform VW (see FIG. 5) indicates the output voltage of a vibration sensor (not shown) attached to the touch pad 42. The output voltage of the vibration waveform VW is proportional to the acceleration on the touch pad 42.

As shown in FIGS. 4 to 6, the control unit 22 has a generation signal Sg1 and Sg2 which are drive signals for generating vibration on the touchpad 42, and an attenuation which is a drive signal for attenuating the vibration generated on the touchpad 42. The signals Sa1 and Sa2 are output to the vibration generating unit 21. The generated signals Sg1 and Sg2 are specific examples of the "first generated signal" and the "second generated signal" in the present invention, respectively.

The control unit 22 outputs the generated signal Sg1, stops the output of the drive signal for a predetermined interruption period S1, and then outputs the generated signal Sg2. The generated signal Sg2 includes a generated signal Sg21 having a negative voltage and a generated signal Sg22 having a positive voltage. Here, the amplitude V2 of the generated signal Sg2 is larger than the amplitude V1 of the generated signal Sg1. Preferably, the amplitude V2 is 15.4 times or more and 18.8 times or less the amplitude V1. In this embodiment, the amplitude V1 is 0.45 volt because the generated signal Sg1 is a signal that oscillates between a voltage of +0.45 volt and a voltage of −0.45 volt. Further, since the generated signal Sg21 has a peak value of −7.7 volt and the generated signal Sg22 has a peak value of +7.7 volt, the amplitude V2 is 7.7 volt. The suspension period S1 is a specific example of the "first suspension period" in the present invention.

The length of the generation period G1 at which the generation signal Sg1 is output is 19446 μs (microseconds). The length of the generation period G1 may be larger than 19446 μs or smaller than 19446 μs. The length of the interruption period S1 is longer than the generation period G2 in which the control unit 22 outputs the generation signal Sg2. Preferably, the length of the interruption period S1 is 14.6 times or more and 17.8 times or less the length of the generation period G2 in which the control unit 22 outputs the generation signal Sg2. In this embodiment, the length of the interruption period S1 is 65535 μs. The length of the generation period G2 is 4050 μs. Here, the length of the period during which the generated signal Sg21 is output is 2130 μs, and the length of the period during which the generated signal Sg22 is output is 1920 μs.

After outputting the generation signal Sg2, the control unit 22 stops the output of the drive signal for a predetermined interruption period S2, and then outputs the attenuation signal Sa1. Then, after outputting the attenuation signal Sa1, the control unit 22 stops the output of the drive signal during a predetermined interruption period S3, and then outputs the attenuation signal Sa2 (see FIG. 6). In this embodiment, the lengths of the interruption periods S2 and S3 are 2000 μs and 1040 μs, respectively. The attenuation signals Sa1 and Sa2 have peak values of +8.0 volt and -5.0 volt, respectively. The length of the attenuation period A1 at which the attenuation signal Sa1 is output is 1280 μs. Further, the length of the attenuation period A2 at which the attenuation signal Sa2 is output is 1680 μs. The suspension period S2 is a specific example of the "second suspension period" in the present invention.

Here, a process when the control unit 22 receives a latch lock vibration generation command from the main body unit 44 will be described. Upon receiving the latch lock vibration generation command from the main body 44, the control unit 22 sets the generation period G1, the suspension period S1, the generation period G2, the suspension period S2, the damping period A1, the suspension period S3, and the damping period A2. The occurrence period G1, the interruption period S1, the occurrence period G2, the interruption period S2, the attenuation period A1, the interruption period S3, and the attenuation period A2 are continuous in this order. That is, the end timing of the occurrence period G1 and the start timing of the interruption period S1 coincide with each other. The same applies to other periods.

The start timing and end timing of the generation periods G1 and G2, the interruption periods S1, S2 and S3, and the attenuation periods A1 and A2 are, for example, the count value of the counter 23 at the timing when the latch lock vibration generation command is received, that is, the latch lock vibration generation command. Calculated based on the time of receipt. The control unit 22 monitors the count value in the counter 23, and based on the time elapsed from the time when the latch lock vibration generation command is received, the control unit 22 has the generation periods G1 and G2, the interruption periods S1, S2 and S3, and the attenuation periods A1 and A2. Recognize the start timing and end timing.

The control unit 22 outputs the generation signal Sg1 to the vibration generation unit 21 from the start timing of the generation period G1 to the end timing of the generation period G1. The amplitude or voltage of the generated signal Sg1 is set based on, for example, the amount of vibration to be generated on the touch pad 42. As shown in the vibration waveform VW, the generated signal Sg1 causes weak vibration in the touch pad 42.

The control unit 22 stops the output of the drive signal from the start timing of the interruption period S1 to the end timing of the interruption period S1. As a result, the weak vibration generated in the touch pad 42 is gradually attenuated.

The control unit 22 outputs the generation signal Sg2 to the vibration generation unit 21 from the start timing of the generation period G2 to the end timing of the generation period G2. The amplitude or voltage of the generated signal Sg2 is set based on, for example, the amount of vibration to be generated on the touch pad 42. As shown in the vibration waveform VW, strong vibration is generated in the touch pad 42 by the generated signal Sg2.

Then, the control unit 22 stops the output of the drive signal from the start timing of the interruption period S2 to the end timing of the interruption period S2, and then from the start timing of the attenuation period A1 to the end timing of the attenuation period A1. The damping signal Sa1 is output to the vibration generating unit 21. Further, the control unit 22 stops the output of the drive signal from the start timing of the interruption period S3 to the end timing of the interruption period S3, and then from the start timing of the attenuation period A2 to the end timing of the attenuation period A2. The damping signal Sa2 is output to the vibration generating unit 21. As a result, the strong vibration generated in the touch pad 42 can be attenuated in a short time, and the end of the strong vibration can be clarified.
