Further, the number of vibrators is not limited to four as shown in FIG. 3, and it is sufficient that two or more vibrators are provided. The mode of vibration generated by the vibration generator 80 can be changed by changing factors such as amplitude, frequency, phase, and duty.
　制御部９０は、振動発生部８０を含めた電子機器１全体の制御を行う。この制御部９０は、その機能部としての振動制御部（不図示）を備えている。この振動制御部は、振動発生部８０に振動信号を出力することにより、振動発生部８０の振動を制御する。なお、以下の説明においては、この振動制御部が行う制御を、制御部９０が行う制御として説明する。 The control unit 90 controls the entire electronic device 1 including the vibration generating unit 80. The control unit 90 includes a vibration control unit (not shown) as the functional unit. The vibration control unit controls the vibration of the vibration generating unit 80 by outputting a vibration signal to the vibration generating unit 80. In the following description, the control performed by the vibration control unit will be described as control performed by the control unit 90.
　記憶部６０は、例えば、フラッシュメモリ、ＨＤＤ（Hard　Disk　Drive）、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、レジスタなどの記憶装置である。記憶部６０には、制御部９０のＣＰＵ（Central　Processing　Unit）が実行するプログラム（ファームウェア）が予め格納される。また、記憶部６０には、ＣＰＵが演算処理を行った演算結果が格納される。また、記憶部６０には、他装置から通信部５０を介して受信したコンテンツデータ、Ｉ／Ｏ部５２に装着された機器から読み出されたコンテンツデータなどが格納される。また、記憶部６０には、タッチパネル１０に表示させる画像の元データとなる画像データ６２の他、例えば、制御部９０が振動発生部８０を制御するための情報として、例えば、画像データ６２に対応付けられた定位データ６４が格納されている。この定位データ６４について、図４を参照して説明する。 The storage unit 60 is a storage device such as a flash memory, HDD (Hard Disk Drive), RAM (Random Access Memory), ROM (Read Only Memory), and registers. In the storage unit 60, a program (firmware) executed by a CPU (Central Processing Unit) of the control unit 90 is stored in advance. In addition, the storage unit 60 stores a calculation result obtained by the CPU performing a calculation process. In addition, the storage unit 60 stores content data received from another apparatus via the communication unit 50, content data read from a device attached to the I / O unit 52, and the like. The storage unit 60 corresponds to, for example, the image data 62 as information for the control unit 90 to control the vibration generating unit 80 in addition to the image data 62 that is the original data of the image displayed on the touch panel 10. The attached localization data 64 is stored. The localization data 64 will be described with reference to FIG.
　図４は、本実施形態の記憶部６０に記憶される画像データ６２と定位データ６４との関係を例示した図である。定位データ６４では、例えば、画像データ６２に含まれる各動画像に対して、定位の振動を発生させる期間と、振動定位の座標と、基準振幅に関するデータとが対応付けられている。なお、図４では、画像データ６２として動画像のデータが保持されるものとしたが、画像データ６２として静止画像のデータが保持されるものとしてもよい。また、定位データ６４は、画像データ６２と関連付けられていなくてもよい。また、制御部９０が、定位データ６４をリアルタイムに生成してもよい。 FIG. 4 is a diagram illustrating the relationship between the image data 62 and the localization data 64 stored in the storage unit 60 of the present embodiment. In the localization data 64, for example, for each moving image included in the image data 62, a period in which the localization vibration is generated, the coordinates of the vibration localization, and data related to the reference amplitude are associated with each other. In FIG. 4, moving image data is held as the image data 62, but still image data may be held as the image data 62. Further, the localization data 64 may not be associated with the image data 62. Further, the control unit 90 may generate the localization data 64 in real time.
　ここで、振動定位とは、電子機器１がユーザの掌Ｐによって保持された状態において、ユーザに振動が発生していると感じさせたい位置である。換言すれば、振動定位とは、電子機器１を保持するユーザによって振動が発生している位置として認識される位置である。以下の説明において、この振動定位を、振動の定位とも記載する。制御部９０は、この定位データ６４に基づいて、振動定位を制御する。なお、以下の説明において、振動定位を制御することを、振動を定位させるとも記載する。ここで、振動定位を制御するとは、制御部９０が各振動子の振動態様を制御することにより、ユーザに振動が発生していると感じさせたい空間内のある座標に振動を定位させるように制御することである。次に、制御部９０が、定位データに基づいて振動を定位させる仕組みについて説明する。 Here, the vibration localization is a position where the user wants to feel that vibration is occurring in a state where the electronic device 1 is held by the palm P of the user. In other words, the vibration localization is a position recognized as a position where vibration is generated by a user holding the electronic device 1. In the following description, this vibration localization is also referred to as vibration localization. The control unit 90 controls the vibration localization based on the localization data 64. In the following description, controlling vibration localization is also referred to as localization of vibration. Here, controlling the vibration localization means that the control unit 90 controls the vibration mode of each vibrator so that the vibration is localized at a certain coordinate in a space where the user wants to feel that the vibration is occurring. Is to control. Next, a mechanism in which the control unit 90 localizes vibration based on the localization data will be described.
［振動定位の制御］
　図５は、本実施形態の電子機器１が制御する振動定位の一例を示す模式図である。この図５において、位置Ｐｖ０とは、電子機器１がタッチパネル１０を上側にしてユーザの掌Ｐによって保持された状態において、ユーザに振動が発生していると感じさせたい位置である。制御部９０は、振動定位の制御を行うことにより、位置Ｐｖ０に振動が発生しているとユーザに感じさせることができる。このように、振動子が配置されていない位置で振動が発生していると感じさせることができる効果は、定位感と称される。定位感とは、ファントム・センセーション（Phantom　Sensation）、すなわち、ユーザの皮膚の２点以上の位置を同時に振動させた（刺激した）場合に、その２点以上の位置の間に在る特定の位置に、あたかも振動の定位があるようにユーザが感じる感覚である。 [Control of vibration localization]
FIG. 5 is a schematic diagram illustrating an example of vibration localization controlled by the electronic apparatus 1 of the present embodiment. In FIG. 5, the position Pv <b> 0 is a position where the user wants to feel that vibration is occurring in a state where the electronic device 1 is held by the user's palm P with the touch panel 10 facing upward. The control unit 90 can make the user feel that vibration is occurring at the position Pv0 by controlling the vibration localization. Thus, the effect that allows the user to feel that the vibration is generated at the position where the vibrator is not arranged is referred to as a sense of localization. A sense of orientation is phantom sensation, that is, a specific position between two or more positions when two or more positions on the user's skin are vibrated (stimulated) at the same time. In addition, the user feels as if the vibration is localized.
　制御部９０は、例えば、振動子８０（１）～８０（４）の位置を、振動の強度で重み付けした重心の位置が位置Ｐｖ０に一致するように、振動子８０（１）～８０（４）を振動させる。振動の強度とは、振幅、周波数など、或いはこれらの組み合わせを意味し、以下では振幅であるものとする。また、各振動子は、例えば背面カバー３０に取り付けられるため、図５に示す状態でユーザの掌Ｐによって保持されることで、ユーザの掌Ｐに振動が伝達され易くなっている。 For example, the control unit 90 controls the vibrators 80 (1) to 80 (4) so that the position of the center of gravity obtained by weighting the positions of the vibrators 80 (1) to 80 (4) with the vibration intensity matches the position Pv0. ). The intensity of vibration means amplitude, frequency, etc., or a combination thereof, and hereinafter, it is assumed to be amplitude. Further, since each vibrator is attached to the back cover 30, for example, vibration is easily transmitted to the user's palm P by being held by the user's palm P in the state shown in FIG.
　図６は、本実施形態の各振動子の振幅の組み合わせの一例を示す模式図である。この図６においては、位置Ｐｖ０に、振幅で重み付けした重心が一致する振動子８０（１）～８０（４）の振幅の組み合わせを例示している。図６において、電子機器１のＸＹ方向に関する中心線の交点をＸＹ平面の原点（Ｘ，Ｙ）＝（０，０）と定義した。そして、振動子８０（１）の座標を（Ｘ，Ｙ）＝（＋０．９，＋０．９）、振動子８０（２）の座標を（Ｘ，Ｙ）＝（－０．９，＋０．９）、振動子８０（３）の座標を（Ｘ，Ｙ）＝（＋０．９，－０．９）、振動子８０（４）の座標を（Ｘ，Ｙ）＝（－０．９，－０．９）、位置Ｐｖ０の座標を（Ｘ，Ｙ）＝（０，－０．５）とした。ここで、振動子が振動していない場合の振幅が０（ゼロ）×Ｋであり、振動子が発生可能な最大の振動の振幅が１×Ｋである。
　このＫとは、基準振幅である。この場合、制御部９０は、例えば、振動子８０（１）を振幅０．４５×Ｋで振動させ、振動子８０（３）を振幅０．５５×Ｋで振動させ、振動子８０（４）を振幅１×Ｋで振動させる（以下、制御状態１とする）ことにより、電子機器１を図５の状態で保持するユーザに、位置Ｐｖ０の付近で振動が発生していると感じさせることができる。
　なお、この設定においては、振動子８０（２）は振動させない（振幅０×Ｋ）。 FIG. 6 is a schematic diagram illustrating an example of a combination of amplitudes of the vibrators of the present embodiment. FIG. 6 illustrates a combination of amplitudes of the transducers 80 (1) to 80 (4) in which the center of gravity weighted with the amplitude coincides with the position Pv0. In FIG. 6, the intersection of the center lines in the XY direction of the electronic device 1 is defined as the origin (X, Y) = (0, 0) of the XY plane. The coordinates of the vibrator 80 (1) are (X, Y) = (+ 0.9, +0.9), and the coordinates of the vibrator 80 (2) are (X, Y) = (− 0.9, +0. 9) The coordinates of the vibrator 80 (3) are (X, Y) = (+ 0.9, −0.9), and the coordinates of the vibrator 80 (4) are (X, Y) = (− 0.9, −0.9), and the coordinates of the position Pv0 are (X, Y) = (0, −0.5). Here, the amplitude when the vibrator is not vibrating is 0 (zero) × K, and the amplitude of the maximum vibration that can be generated by the vibrator is 1 × K.
This K is a reference amplitude. In this case, for example, the control unit 90 vibrates the vibrator 80 (1) with an amplitude of 0.45 × K, vibrates the vibrator 80 (3) with an amplitude of 0.55 × K, and vibrates the vibrator 80 (4). Is vibrated with an amplitude of 1 × K (hereinafter referred to as control state 1), the user holding the electronic apparatus 1 in the state of FIG. 5 may feel that vibration is occurring in the vicinity of the position Pv0. it can.
In this setting, the vibrator 80 (2) is not vibrated (amplitude 0 × K).
　すなわち、下記の式（１）、（２）に示すように、振動子８０（１）～振動子８０（４）からの各振動のＸ方向成分の振動、及び、Ｙ方向成分の振動がそれぞれ加減されることによって、位置Ｐｖ０の座標（Ｘ，Ｙ）＝（０，－０．５）の付近において、振動が発生しているとユーザに感じさせることができる。式（１）は、Ｘ方向成分における振動子８０（１）～振動子８０（４）の各振動の加減を表す。式（２）は、Ｙ方向成分における振動子８０（１）～振動子８０（４）の各振動の加減を表す。 That is, as shown in the following formulas (1) and (2), the vibration in the X direction component and the vibration in the Y direction component of each vibration from the vibrators 80 (1) to 80 (4) are respectively By adjusting, the user can feel that vibration is occurring in the vicinity of the coordinate (X, Y) = (0, −0.5) of the position Pv0. Expression (1) represents the addition or subtraction of each vibration of the vibrator 80 (1) to the vibrator 80 (4) in the X direction component. Expression (2) represents the addition or subtraction of each vibration of the vibrator 80 (1) to the vibrator 80 (4) in the Y direction component.

　上記の式（１）において、振動子８０（１）が寄与している項は、（＋０．９×０．４５×Ｋ）であり、振動子８０（３）が寄与している項は、（＋０．９×０．５５×Ｋ）であり、振動子８０（４）が寄与している項は、（－０．９×１×Ｋ）である。 In the above equation (1), the term to which the vibrator 80 (1) contributes is (+ 0.9 × 0.45 × K), and the term to which the vibrator 80 (3) contributes is (+ 0.9 × 0.55 × K), and the term to which the vibrator 80 (4) contributes is (−0.9 × 1 × K).
　上記の式（２）において、振動子８０（１）が寄与している項は、（＋０．９×０．４５×Ｋ）であり、振動子８０（３）が寄与している項は、（－０．９×０．５５×Ｋ）であり、振動子８０（４）が寄与している項は、（－０．９×１×Ｋ）である。 In the above equation (2), the term to which the vibrator 80 (1) contributes is (+ 0.9 × 0.45 × K), and the term to which the vibrator 80 (3) contributes is (−0.9 × 0.55 × K), and the term to which the vibrator 80 (4) contributes is (−0.9 × 1 × K).
　また、制御部９０は、上記制御状態１に代えて、振動子８０（２）を振幅０．４５×Ｋで振動させ、振動子８０（３）を振幅１×Ｋで振動させ、振動子８０（４）を振幅０．５５×Ｋで振動させてもよい（制御状態２）。また、制御部９０は、振動子８０（１）および振動子８０（２）を振幅０．２２×Ｋで振動させ、振動子８０（３）および振動子８０（４）を振幅０．７８×Ｋで振動させてもよい（制御状態３）。このように、振幅で重み付けした重心の位置が位置Ｐｖ０に一致する振動態様の組み合わせは複数存在し、制御部９０は、任意の制御状態を選択することにより、ユーザに位置Ｐｖ０で振動が発生していると感じさせることができる。なお、上記した０．４５、０．５５、１、０．２２、０．７８といった数値はあくまで一例であり、制御部９０は、重心を位置Ｐｖ０に一致させることができれば、任意の数値を設定することができる。 Further, instead of the control state 1, the control unit 90 vibrates the vibrator 80 (2) with an amplitude of 0.45 × K and vibrates the vibrator 80 (3) with an amplitude of 1 × K. (4) may be vibrated with an amplitude of 0.55 × K (control state 2). In addition, the control unit 90 vibrates the vibrator 80 (1) and the vibrator 80 (2) with an amplitude of 0.22 × K, and causes the vibrator 80 (3) and the vibrator 80 (4) to have an amplitude of 0.78 × You may vibrate with K (control state 3). As described above, there are a plurality of combinations of vibration modes in which the position of the center of gravity weighted by the amplitude coincides with the position Pv0, and the control unit 90 causes the user to vibrate at the position Pv0 by selecting an arbitrary control state. You can make them feel. The numerical values such as 0.45, 0.55, 1, 0.22, and 0.78 described above are merely examples, and the control unit 90 sets an arbitrary numerical value as long as the center of gravity can be matched with the position Pv0. can do.
［振動定位の移動の軌跡を強調する制御］
　次に、制御部９０が振動定位を移動させる場合に、この移動の軌跡を強調する制御の一例について、図７および図８を参照して説明する。
　図７は、本実施形態の電子機器１が制御する振動定位の移動の軌跡の一例を示す模式図である。制御部９０は、定位データに基づく各振動子の振幅を、時刻の経過とともに変化させることにより、振動定位を移動させる制御を行う。ここで、図７に示す位置Ｐｖ１から位置Ｐｖ２に軌跡ＬＣ１に沿って振動定位を移動させる場合を具体例として説明する。
　ここで、軌跡ＬＣ１とは、振動子８０（１）と振動子８０（４）とを結ぶ線分の一部である。また、この一例においては、振動子８０（１）が、振動定位の移動元の振動子であり、振動子８０（４）が、振動定位の移動先の振動子である。 [Control to emphasize the trajectory of vibration localization movement]
Next, an example of control for emphasizing the movement locus when the control unit 90 moves the vibration localization will be described with reference to FIGS.
FIG. 7 is a schematic diagram illustrating an example of a locus of vibration localization movement controlled by the electronic apparatus 1 of the present embodiment. The control unit 90 performs control to move the vibration localization by changing the amplitude of each vibrator based on the localization data as time passes. Here, a case where the vibration localization is moved along the locus LC1 from the position Pv1 to the position Pv2 shown in FIG. 7 will be described as a specific example.
Here, the locus LC1 is a part of a line segment connecting the vibrator 80 (1) and the vibrator 80 (4). In this example, the vibrator 80 (1) is a vibration source movement source vibrator, and the vibrator 80 (4) is a vibration position movement destination vibrator.
　この具体例の場合、制御部９０は、まず位置Ｐｖ１に振動を定位させる。このとき制御部９０は、上述した位置Ｐｖ０に振動を定位させる場合と同様に、定位データに基づいて各振動子の振動態様を制御して、位置Ｐｖ１に振動を定位させる。具体的には、制御部９０は、振動子８０（２）、振動子８０（３）の振動を停止させるとともに、振動子８０（１）の振動の振幅と、振動子８０（４）の振動の振幅とを制御して、位置Ｐｖ１に振動を定位させる。ここで、振動子の振動を停止させる場合、制御部９０は、制御部９０から振動子に出力する駆動信号の出力を停止する。また、制御部９０は、振動子の振幅が０（ゼロ）になるようにした駆動信号を出力することにより、振動子の振動を停止させてもよい。 In the case of this specific example, the control unit 90 first localizes the vibration at the position Pv1. At this time, similarly to the case where the vibration is localized at the position Pv0 described above, the control unit 90 controls the vibration mode of each vibrator based on the localization data to localize the vibration at the position Pv1. Specifically, the control unit 90 stops the vibration of the vibrator 80 (2) and the vibrator 80 (3), and the vibration amplitude of the vibrator 80 (1) and the vibration of the vibrator 80 (4). And the vibration is localized at the position Pv1. Here, when stopping the vibration of the vibrator, the control unit 90 stops the output of the drive signal output from the control unit 90 to the vibrator. Further, the control unit 90 may stop the vibration of the vibrator by outputting a drive signal in which the vibrator has an amplitude of 0 (zero).
　また、制御部９０は、振動子８０（１）の振動の振幅を、振動子８０（４）の振幅よりも大きい振幅にして、振動子８０（１）と振動子８０（４）とを振動させる。このとき制御部９０は、振動子８０（１）の振動の振幅と、振動子８０（４）の振幅との比率を変化させることにより、軌跡ＬＣ１上の任意の座標に振動を定位させることができる。この一例においては、制御部９０は、振動子８０（１）の振動の振幅を０～１×Ｋの範囲内のある振幅にして、振動子８０（１）を振動させる。また、制御部９０は、振動子８０（４）の振動の振幅を０～１×Ｋの範囲内の、振動子８０（１）の振幅よりも小さい振幅にして、振動子８０（４）を振動させる。つまり、制御部９０は、振動定位の移動の軌跡に基づいて選択される少なくとも２つの振動子を、それぞれ振動させる。これにより、位置Ｐｖ１に振動が定位する。 Further, the control unit 90 vibrates the vibrator 80 (1) and the vibrator 80 (4) by setting the vibration amplitude of the vibrator 80 (1) to an amplitude larger than the amplitude of the vibrator 80 (4). Let At this time, the control unit 90 can localize the vibration to an arbitrary coordinate on the locus LC1 by changing the ratio between the amplitude of the vibration of the vibrator 80 (1) and the amplitude of the vibrator 80 (4). it can. In this example, the control unit 90 causes the vibrator 80 (1) to vibrate by setting the vibration amplitude of the vibrator 80 (1) to a certain amplitude within the range of 0 to 1 × K. Further, the control unit 90 sets the vibrator 80 (4) to an amplitude smaller than the amplitude of the vibrator 80 (1) within the range of 0 to 1 × K. Vibrate. That is, the control unit 90 vibrates at least two vibrators selected based on the locus of movement of the vibration localization. Thereby, the vibration is localized at the position Pv1.
　次に、制御部９０は、振動定位が位置Ｐｖ１から位置Ｐｖ２に移動するように、各振動子の振動態様を制御する。具体的には、制御部９０は、時間の経過とともに振動子８０（１）の振動の振幅を漸減させつつ、振動子８０（４）の振幅を漸増させる。これにより、振動子８０（１）の振動の振幅と、振動子８０（４）の振幅との比率が変化し、振動定位が位置Ｐｖ１から位置Ｐｖ２に移動する。ここで、本実施形態の制御部９０は、振動定位を移動させる場合に、各振動子の振動の振幅に加えて、振動の周波数を制御する。この制御部９０が制御する振動子の振動波形の一例について、図８を参照して説明する。 Next, the control unit 90 controls the vibration mode of each vibrator so that the vibration localization moves from the position Pv1 to the position Pv2. Specifically, the control unit 90 gradually increases the amplitude of the vibrator 80 (4) while gradually decreasing the amplitude of vibration of the vibrator 80 (1) as time passes. As a result, the ratio between the amplitude of the vibration of the vibrator 80 (1) and the amplitude of the vibrator 80 (4) changes, and the vibration localization moves from the position Pv1 to the position Pv2. Here, when the vibration localization is moved, the control unit 90 of the present embodiment controls the vibration frequency in addition to the vibration amplitude of each vibrator. An example of the vibration waveform of the vibrator controlled by the control unit 90 will be described with reference to FIG.
　図８は、本実施形態の制御部９０が出力する駆動信号の波形の一例を示すグラフである。この図８の各グラフにおいて、横軸は時刻ｔを示し、縦軸は振動子の振動の振幅の大きさＡを示す。制御部９０は、上述の一例において、振動定位を位置Ｐｖ１から位置Ｐｖ２に移動させる場合に、図８（Ａ）に示す波形Ｗ１Ａの駆動信号を振動子８０（４）に出力する。また、この場合に、制御部９０は、図８（Ｂ）に示す波形Ｗ１Ｂの駆動信号を振動子８０（１）に出力する。ここで、時刻ｔ１から時刻ｔ４までの時間は、一例として２００［ｍｓ］である。なお、この波形Ｗ１Ａおよび波形Ｗ１Ｂは、定位データ６４として記憶部６０に予め記憶されていてもよく、制御部９０の演算によって生成されてもよい。 FIG. 8 is a graph showing an example of the waveform of the drive signal output by the control unit 90 of the present embodiment. In each graph of FIG. 8, the horizontal axis indicates the time t, and the vertical axis indicates the amplitude A of the vibration of the vibrator. In the above example, when the vibration localization is moved from the position Pv1 to the position Pv2, the control unit 90 outputs a drive signal having a waveform W1A shown in FIG. 8A to the vibrator 80 (4). In this case, the control unit 90 outputs a drive signal having a waveform W1B shown in FIG. 8B to the vibrator 80 (1). Here, the time from time t1 to time t4 is 200 [ms] as an example. Note that the waveform W1A and the waveform W1B may be stored in advance in the storage unit 60 as the localization data 64, or may be generated by calculation of the control unit 90.
　この波形Ｗ１Ａとは、波形Ｗ１Ａの振幅の包絡線Ｅｎｖ１Ａが示すように、時刻ｔの経過とともに振幅が漸増する駆動信号の一例である。また、波形Ｗ１Ｂとは、波形Ｗ１Ｂの振幅の包絡線Ｅｎｖ１Ｂが示すように、時刻ｔの経過とともに振幅が漸減する駆動信号の一例である。制御部９０は、波形Ｗ１Ｂの駆動信号を振動子８０（１）に供給することにより、振動子８０（１）の振動の振幅を漸減させる。また、制御部９０は、波形Ｗ１Ａの駆動信号を振動子８０（４）に供給することにより、振動子８０（４）の振動の振幅を漸増させる。これにより、制御部９０は、振動定位を位置Ｐｖ１から位置Ｐｖ２に軌跡ＬＣ１に沿って移動させる。 This waveform W1A is an example of a drive signal whose amplitude gradually increases as time t passes, as indicated by the envelope Env1A of the amplitude of the waveform W1A. The waveform W1B is an example of a drive signal whose amplitude gradually decreases as time t passes, as indicated by the envelope Env1B of the amplitude of the waveform W1B. The controller 90 gradually decreases the amplitude of vibration of the vibrator 80 (1) by supplying the drive signal having the waveform W1B to the vibrator 80 (1). Further, the controller 90 gradually increases the amplitude of the vibration of the vibrator 80 (4) by supplying the drive signal having the waveform W1A to the vibrator 80 (4). Thereby, the control unit 90 moves the vibration localization from the position Pv1 to the position Pv2 along the locus LC1.
　ここで、制御部９０は、振動子８０（１）を第１の周波数ｆ１で振動させ、振動子８０（４）を第１の周波数ｆ１とは異なる第２の周波数ｆ２で振動させる。具体的には、波形Ｗ１Ａの周波数は、波形Ｗ１Ｂの周波数よりも低い。さらに具体的には、波形Ｗ１Ａの周波数は５０［Ｈｚ］であり、波形Ｗ１Ｂの周波数は２００［Ｈｚ］である。以下の説明において、波形Ｗ１Ｂの周波数を、比較の基準周波数としての、第１の周波数ｆ１とも記載する。また、波形Ｗ１Ａの周波数を、第２の周波数ｆ２とも記載する。 Here, the control unit 90 vibrates the vibrator 80 (1) at the first frequency f1, and vibrates the vibrator 80 (4) at the second frequency f2 different from the first frequency f1. Specifically, the frequency of the waveform W1A is lower than the frequency of the waveform W1B. More specifically, the frequency of the waveform W1A is 50 [Hz], and the frequency of the waveform W1B is 200 [Hz]. In the following description, the frequency of the waveform W1B is also referred to as a first frequency f1 as a reference frequency for comparison. The frequency of the waveform W1A is also referred to as the second frequency f2.
　また、この一例においては、第１の周波数ｆ１は２００［Ｈｚ］であり、第２の周波数ｆ２は、第１の周波数ｆ１よりも低い５０［Ｈｚ］である。すなわち、制御部９０は、振動子８０（１）を第１の周波数ｆ１で振動させ、振動子８０（４）を第１の周波数ｆ１よりも低い第２の周波数ｆ２で振動させる。上述したように、振動子８０（１）とは、振動定位の移動の軌跡の移動元側を示す振動子として複数の振動子から選択される振動子の一例である。また、振動子８０（４）とは、振動定位の移動の軌跡の移動先側を示す振動子として複数の振動子から選択される振動子の一例である。すなわち、制御部９０は、振動定位の移動の軌跡の移動元側を示す振動子として複数の振動子から選択される振動子８０（１）を第１の周波数ｆ１によって振動させる。また、制御部９０は、振動定位の移動の軌跡の移動先側を示す振動子として複数の振動子から選択される振動子８０（４）を第１の周波数ｆ１よりも低い第２の周波数ｆ２によって振動させる。 Further, in this example, the first frequency f1 is 200 [Hz], and the second frequency f2 is 50 [Hz] lower than the first frequency f1. That is, the control unit 90 vibrates the vibrator 80 (1) at the first frequency f1, and vibrates the vibrator 80 (4) at the second frequency f2 that is lower than the first frequency f1. As described above, the vibrator 80 (1) is an example of a vibrator selected from a plurality of vibrators as a vibrator indicating the movement source side of the locus of movement of vibration localization. The vibrator 80 (4) is an example of a vibrator selected from a plurality of vibrators as a vibrator indicating the movement destination side of the locus of movement of vibration localization. That is, the control unit 90 vibrates the vibrator 80 (1) selected from the plurality of vibrators as the vibrator indicating the movement source side of the vibration localization movement locus at the first frequency f1. In addition, the control unit 90 sets the vibrator 80 (4) selected from the plurality of vibrators as the vibrator indicating the movement destination side of the vibration localization movement locus to the second frequency f2 lower than the first frequency f1. Vibrate by.
　換言すれば、制御部９０は、振動定位の軌跡ＬＣ１の移動元（例えば、位置Ｐｖ１の付近）においては、高い周波数の成分が多くなるようにして、各振動子を振動させる。また、制御部９０は、振動定位の軌跡ＬＣ１の移動先（例えば、位置Ｐｖ２の付近）においては、低い周波数の成分が多くなるようにして、各振動子を振動させる。なお、以下の説明において、振動子が振動する周波数の成分のうち、相対的に高い周波数の成分を「高周波成分」とも記載し、相対的に低い周波数の成分を「低周波成分」とも記載する。 In other words, the control unit 90 vibrates each vibrator so that a high frequency component increases in the movement source of the vibration localization locus LC1 (for example, in the vicinity of the position Pv1). In addition, the control unit 90 vibrates each vibrator so that a low frequency component is increased at the destination of the vibration localization locus LC1 (for example, near the position Pv2). In the following description, among the frequency components at which the vibrator vibrates, a relatively high frequency component is also referred to as a “high frequency component”, and a relatively low frequency component is also referred to as a “low frequency component”. .
　ここで、電子機器１を保持するユーザの掌Ｐに振動が伝達される際に、振動の周波数が低い場合には、振動の周波数が高い場合に比べて、ユーザが感じる振動定位の印象が強いことがある。このため、制御部９０は、振動定位を軌跡ＬＣ１に沿って移動させる場合に、移動元における振動の周波数よりも移動先における振動の周波数を低くする。これにより、電子機器１は、振動定位の移動の軌跡ＬＣ１に沿って何らかの物体が移動したかのような強い印象をユーザに与えることができる。
　ここで電子機器１が与える強い印象には、振動定位の移動の軌跡ＬＣ１、すなわち振動定位の移動方向に向けて電子機器１自体が動いているような印象を含む。また、この電子機器１が与える強い印象には、振動定位の移動が止まった後に、振動定位の移動の余韻が生じているような印象を含む。このように振動定位の移動先の振動子が、移動元の振動子に比べて低周波数で振動することにより、振動定位の移動先の印象が強調される。 Here, when the vibration is transmitted to the palm P of the user holding the electronic device 1, when the vibration frequency is low, the impression of the vibration localization felt by the user is stronger than when the vibration frequency is high. Sometimes. For this reason, when moving the vibration localization along the trajectory LC1, the control unit 90 lowers the vibration frequency at the movement destination lower than the vibration frequency at the movement source. Thereby, the electronic device 1 can give a strong impression to the user as if some object has moved along the locus LC1 of movement of the vibration localization.
Here, the strong impression given by the electronic device 1 includes an impression that the electronic device 1 itself is moving toward the movement path LC1 of the vibration localization, that is, the movement direction of the vibration localization. In addition, the strong impression given by the electronic device 1 includes an impression that the reverberation of the movement of the vibration localization occurs after the movement of the vibration localization stops. As described above, the vibration-destination moving destination vibrator vibrates at a lower frequency than the movement-source vibrator, thereby enhancing the impression of the vibration localization moving destination.
　なお、この具体例においては、波形Ｗ１Ａの周波数は５０［Ｈｚ］であり、波形Ｗ１Ｂの周波数は２００［Ｈｚ］であるとして説明したが、波形Ｗ１Ａの周波数は、波形Ｗ１Ｂの周波数よりも低ければよく、この数値に限定されるものではない。 In this specific example, the frequency of the waveform W1A is 50 [Hz] and the frequency of the waveform W1B is 200 [Hz]. However, if the frequency of the waveform W1A is lower than the frequency of the waveform W1B. Well, it is not limited to this number.
　ここで、ユーザの皮膚に存在する様々な感覚受容器が、これらの感覚受容器全体として振動を受容する場合の周波数特性は、約０．３～１０００［Ｈｚ］である。これらの感覚受容器のうち、上述したファントム・センセーションを生じさせる刺激を受容する感覚受容器としては、パチニ小体がある。このパチニ小体が振動を受容する場合の周波数特性は、約３０～１０００［Ｈｚ］である。したがって、ファントム・センセーションを生じさせるための各振動子の振動周波数は、約４０～１０００［Ｈｚ］であることが好ましい。 Here, the frequency characteristics when various sensory receptors present on the user's skin receive vibration as a whole of these sensory receptors are approximately 0.3 to 1000 [Hz]. Among these sensory receptors, as a sensory receptor that receives a stimulus that causes the above-described phantom sensation, there is a Patini body. The frequency characteristic when the Patinny body receives vibration is about 30 to 1000 [Hz]. Therefore, the vibration frequency of each vibrator for generating phantom sensation is preferably about 40 to 1000 [Hz].
　また、ユーザの皮膚が、振動子が発生させる振動を振動として知覚できる周波数は、約３００［Ｈｚ］以下である。したがって、振動定位の移動を印象づけるための各振動子の振動周波数は、約３０～３００［Ｈｚ］であることが好ましい。 Further, the frequency at which the user's skin can perceive the vibration generated by the vibrator as a vibration is about 300 [Hz] or less. Therefore, it is preferable that the vibration frequency of each vibrator for impressing the movement of the vibration localization is about 30 to 300 [Hz].
　また、低い周波数である第２の周波数ｆ２と、高い周波数である第１の周波数ｆ１との間の周波数の比が、１：２～１：４程度である場合に、振動定位の移動を強く印象づけることができる。例えば、第２の周波数ｆ２が５０［Ｈｚ］である場合には、第１の周波数ｆ１が１００～２００［Ｈｚ］程度であると、振動定位の移動を強く印象づけることができる。これらのことから、第１の周波数ｆ１は、３０～１５０［Ｈｚ］程度であり、第２の周波数ｆ２は、６０～３００［Ｈｚ］程度であることが好ましい。 Further, when the frequency ratio between the second frequency f2 which is a low frequency and the first frequency f1 which is a high frequency is about 1: 2 to 1: 4, the movement of vibration localization is strongly increased. You can make an impression. For example, when the second frequency f2 is 50 [Hz], if the first frequency f1 is about 100 to 200 [Hz], the movement of vibration localization can be impressed strongly. Therefore, the first frequency f1 is preferably about 30 to 150 [Hz], and the second frequency f2 is preferably about 60 to 300 [Hz].
　また、制御部９０は、時刻ｔの経過に伴って、図８（Ｂ）に示した波形Ｗ１Ｂの駆動信号を振動子８０（１）に供給することにより、振動子８０（１）の振動の振幅を漸減させる。また、制御部９０は、これと同時に、図８（Ａ）に示した波形Ｗ１Ａの駆動信号を振動子８０（４）に供給することにより、振動子８０（４）の振動の振幅を漸増させる。つまり、制御部９０は、振動定位の移動に伴って、振動子８０（１）の振動による高周波成分を漸減させるとともに、振動子８０（４）の振動による低周波成分を漸増させて、複数の振動子をそれぞれ振動させる。これにより、振動子８０（１）の振動の振幅の比率と、振動子８０（４）の振動の振幅の比率とが、時刻ｔの経過とともに滑らかに入れ替わる。そのため、振動定位が滑らかに移動しているようにユーザに感じさせることができる。 Further, the control unit 90 supplies the drive signal having the waveform W1B illustrated in FIG. 8B to the vibrator 80 (1) with the passage of time t, so that the vibration of the vibrator 80 (1) can be reduced. Decrease the amplitude. At the same time, the controller 90 supplies the drive signal having the waveform W1A shown in FIG. 8A to the vibrator 80 (4), thereby gradually increasing the vibration amplitude of the vibrator 80 (4). . That is, the control unit 90 gradually decreases the high frequency component due to the vibration of the vibrator 80 (1) and gradually increases the low frequency component due to the vibration of the vibrator 80 (4) as the vibration localization moves. Each vibrator is vibrated. As a result, the vibration amplitude ratio of the vibrator 80 (1) and the vibration amplitude ratio of the vibrator 80 (4) are smoothly switched as time t passes. Therefore, the user can feel as if the vibration localization is moving smoothly.
　なお、振動子を駆動する駆動信号の包絡線（この一例においては、図８（Ａ）に示した包絡線Ｅｎｖ１Ａ、および図８（Ｂ）に示した包絡線Ｅｎｖ１Ｂ）は、さまざまな関数によって表すことができる。例えば、振幅が漸増する駆動信号の包絡線（この一例においては、包絡線Ｅｎｖ１Ａ）は、一次関数によって表される曲線（すなわち、直線）であってもよく、二次関数や指数関数等によって表される曲線であってもよい。また、ユーザに違和感が生じない程度であれば、包絡線はステップ状に変化してもよい。また、振幅が漸減する駆動信号の包絡線（この一例においては、包絡線Ｅｎｖ１Ｂ）についても同様に、包絡線は一次関数、二次関数、指数関数等によって表される曲線であってもよく、ユーザに違和感が生じない程度であれば、包絡線はステップ状に変化してもよい。制御部９０は、この包絡線を様々に変形させることにより、ユーザが感じる振動定位の移動の印象を変化させることができる。さらに、制御部９０は、タッチパネル１０に表示する画像と、駆動信号を表す関数とを関連付けて制御することにより、画像の内容に応じてユーザが感じる振動定位の移動の印象をさまざまに変化させることができる。 Note that the envelopes of the drive signal for driving the vibrator (in this example, the envelope Env1A shown in FIG. 8A and the envelope Env1B shown in FIG. 8B) are expressed by various functions. be able to. For example, the envelope of the drive signal whose amplitude gradually increases (in this example, the envelope Env1A) may be a curve (that is, a straight line) represented by a linear function, and may be represented by a quadratic function, an exponential function, or the like. It may be a curved line. Further, the envelope may change stepwise as long as the user does not feel uncomfortable. Similarly, for the envelope of the drive signal whose amplitude gradually decreases (in this example, the envelope Env1B), the envelope may be a curve represented by a linear function, a quadratic function, an exponential function, etc. As long as the user does not feel discomfort, the envelope may change stepwise. The controller 90 can change the impression of the movement of the vibration localization felt by the user by variously deforming the envelope. Further, the control unit 90 controls the image displayed on the touch panel 10 in association with the function representing the drive signal, thereby changing the vibration localization movement impression felt by the user according to the content of the image. Can do.
　なお、ここまで、制御部９０が振動定位の軌跡に基づいて予め選択されている振動子に対して、その振幅や振動周波数の制御を行う例について説明したが、これに限られない。
　具体的には、制御部９０は、制御対象の振動子を選択する選択部を、その機能部として備えていてもよい。この選択部は、振動定位の移動の軌跡に基づいて、複数の振動子から一方の振動子と、他方の振動子とを選択する。具体的な一例として、選択部は、図７に示す軌跡ＬＣ１に沿って振動定位を移動させる場合には、振動定位の移動の軌跡の移動元側を示す振動子として振動子８０（１）を選択する。また、この場合に選択部は、振動定位の移動の軌跡の移動先側を示す振動子として振動子８０（４）を選択する。
　また、具体的な他の一例として、図１０に示す軌跡ＬＣ２に沿って振動定位を移動させる場合には、振動定位の移動の軌跡の移動元側を示す振動子として、すべての振動子、すなわち振動子８０（１）～（４）を選択する。また、この場合に選択部は、振動定位の移動の軌跡の移動先側を示す振動子として、すべての振動子、すなわち振動子８０（１）～（４）を選択する。
　このように、電子機器１は、選択部を備えることによって、予め制御対象の振動子が定められていない場合であっても、振動定位を制御することができる。 Heretofore, an example has been described in which the control unit 90 controls the amplitude and vibration frequency of a vibrator that is selected in advance based on the vibration localization locus, but the present invention is not limited to this.
Specifically, the control unit 90 may include a selection unit that selects a transducer to be controlled as its function unit. The selection unit selects one vibrator and the other vibrator from a plurality of vibrators based on the movement locus of the vibration localization. As a specific example, when the selection unit moves the vibration localization along the locus LC1 illustrated in FIG. 7, the selection unit uses the vibrator 80 (1) as the vibrator indicating the movement source side of the vibration localization movement locus. select. In this case, the selection unit selects the vibrator 80 (4) as the vibrator indicating the movement destination side of the locus of movement of the vibration localization.
Further, as another specific example, when the vibration localization is moved along the locus LC2 shown in FIG. 10, all the vibrators, that is, the vibrators indicating the movement source side of the movement locus of the vibration localization, The vibrators 80 (1) to (4) are selected. In this case, the selection unit selects all the vibrators, that is, the vibrators 80 (1) to (4) as the vibrators indicating the movement destination side of the locus of movement of the vibration localization.
As described above, the electronic device 1 includes the selection unit, and thus can control the vibration localization even when the vibrator to be controlled is not determined in advance.
［電子機器１の動作］
　図９は、本実施形態の制御部９０が実行する処理の流れの一例を示すフローチャートである。図９のフローチャートの処理は、例えば、定位データ６４が対応付けられた動画像の再生が行われている間、繰り返し実行される。 [Operation of Electronic Device 1]
FIG. 9 is a flowchart illustrating an example of a flow of processing executed by the control unit 90 of the present embodiment. The process of the flowchart in FIG. 9 is repeatedly executed while a moving image associated with the localization data 64 is being reproduced, for example.
　まず、制御部９０は、定位データ６４を記憶部６０から読み出す（ステップＳ１０）。 First, the control unit 90 reads the localization data 64 from the storage unit 60 (step S10).
　次に、制御部９０は、読み出した定位データ６４を参照して、定位の振動を発生させる期間内であるか否かを判定する（ステップＳ２０）。制御部９０は、定位の振動を発生させる期間内でないと判定した場合（ステップＳ２０：ＮＯ）、図９のフローチャートの１ルーチンを終了する。また、制御部９０は、定位の振動を発生させる期間内であると判定した場合（ステップＳ２０：ＹＥＳ）、処理をステップＳ３０に進める。 Next, the control unit 90 refers to the read localization data 64 and determines whether or not it is within a period in which localization vibration is generated (step S20). If the control unit 90 determines that it is not within the period for generating the localized vibration (step S20: NO), it ends one routine of the flowchart of FIG. In addition, when the control unit 90 determines that it is within the period in which the localization vibration is generated (step S20: YES), the process proceeds to step S30.
　次に、制御部９０は、ステップＳ１０において読み出した定位データ６４に基づいて、制御対象の振動子を選択する（選択ステップ）。また、制御部９０は、この定位データ６４に基づいて、選択した各振動子の振動周波数、振動定位の軌跡、振幅の包絡線（エンベロープ）、すなわち駆動信号のパラメータを算出する（パラメータ算出ステップ）。具体的には、制御部９０は、定位データ６４に基づいて、高周波側の振動周波数（第１の振動周波数）と、低周波側の振動周波数（第２の振動周波数）とを算出する（ステップＳ３０）。一例として、制御部９０は、第１の周波数ｆ１を１００～２００［Ｈｚ］の範囲にし、第２の周波数ｆ２は、６０～３００［Ｈｚ］の範囲にして、各振動子の振動周波数を算出する。また、一例として、制御部９０は、第２の周波数ｆ２と、第１の周波数ｆ１との間の周波数の比が１：２～１：４となるようにして、各振動子の振動周波数を算出する。 Next, the control unit 90 selects a transducer to be controlled based on the localization data 64 read in step S10 (selection step). Further, the control unit 90 calculates the vibration frequency, the locus of vibration localization, the envelope of the amplitude, that is, the parameter of the drive signal, based on the localization data 64 (parameter calculation step). . Specifically, the control unit 90 calculates a high frequency vibration frequency (first vibration frequency) and a low frequency vibration frequency (second vibration frequency) based on the localization data 64 (step) S30). As an example, the control unit 90 calculates the vibration frequency of each vibrator by setting the first frequency f1 in the range of 100 to 200 [Hz] and the second frequency f2 in the range of 60 to 300 [Hz]. To do. Further, as an example, the control unit 90 sets the vibration frequency of each vibrator so that the frequency ratio between the second frequency f2 and the first frequency f1 is 1: 2 to 1: 4. calculate.
　次に、制御部９０は、定位データ６４に基づいて、振動定位の移動の軌跡の開始位置（開始座標）と、終了位置（終了座標）とを算出する（ステップＳ４０）。 Next, the control unit 90 calculates a start position (start coordinate) and an end position (end coordinate) of the trajectory of vibration localization based on the localization data 64 (step S40).
　また、制御部９０は、ステップＳ４０において算出した開始位置（開始座標）と、終了位置（終了座標）と、振動定位の移動速度を示す情報とに基づいて、各振動子の振幅の包絡線（エンベロープ）を算出する（ステップＳ５０）。この振動定位の移動速度を示す情報とは、開始位置（開始座標）から、終了位置（終了座標）までに振動定位が移動する際の速度または時間を示す情報である。 The control unit 90 also determines the amplitude envelope of each transducer based on the start position (start coordinates), end position (end coordinates) calculated in step S40, and information indicating the moving speed of the vibration localization. (Envelope) is calculated (step S50). The information indicating the movement speed of the vibration localization is information indicating the speed or time when the vibration localization moves from the start position (start coordinates) to the end position (end coordinates).
　なお、振動定位の移動速度を示す情報は、定位データ６４に含まれていてもよく、制御部９０が画像データ６２などに基づいて生成してもよい。 Note that the information indicating the movement speed of the vibration localization may be included in the localization data 64, or the control unit 90 may generate the information based on the image data 62 or the like.
　次に、制御部９０は、ステップＳ３０～Ｓ５０において算出した駆動信号のパラメータに基づいて、各振動子に対する駆動信号を生成し（ステップＳ６０）、生成した駆動信号を各振動子に対して出力する（ステップＳ７０）。このステップＳ６０およびステップＳ７０は、振動制御ステップの一例である。 Next, the control unit 90 generates a drive signal for each transducer based on the parameters of the drive signal calculated in steps S30 to S50 (step S60), and outputs the generated drive signal to each transducer. (Step S70). Steps S60 and S70 are an example of a vibration control step.
　また、制御部９０は、振動定位が終了位置（終了座標）に到達したか否かを判定する（ステップＳ８０）。制御部９０は、振動定位が終了位置（終了座標）に到達していないと判定した場合（ステップＳ８０：ＮＯ）には、処理をステップＳ７０に戻して、駆動信号の出力を継続する。また、制御部９０は、振動定位が終了位置（終了座標）に到達したと判定した場合（ステップＳ８０：ＹＥＳ）には、図９のフローチャートの１ルーチンを終了する。 Further, the control unit 90 determines whether or not the vibration localization has reached the end position (end coordinate) (step S80). When it is determined that the vibration localization has not reached the end position (end coordinate) (step S80: NO), the control unit 90 returns the process to step S70 and continues outputting the drive signal. Further, when it is determined that the vibration localization has reached the end position (end coordinate) (step S80: YES), the control unit 90 ends one routine of the flowchart of FIG.
　以上説明した本実施形態の電子機器１、およびその制御プログラム（以下、電子機器１等）によれば、振動が発生しているとユーザに感じさせたい所定の位置に対し、振動子８０（１）～８０（４）の位置を振動の強度で重み付けした重心の位置が所定の位置に一致するように、振動子８０（１）～８０（４）を振動させる。そのため、ユーザに、所定の位置で振動が発生していると感じさせることができ、ユーザに高度な臨場感を提供することができる。 According to the electronic device 1 and the control program (hereinafter, electronic device 1 or the like) of the present embodiment described above, the vibrator 80 (1) is located at a predetermined position that the user wants to feel that vibration is occurring. ) To 80 (4) are vibrated so that the position of the center of gravity obtained by weighting the positions of 80 to (4) with the intensity of vibration matches a predetermined position. Therefore, it is possible to make the user feel that vibration is occurring at a predetermined position, and to provide the user with a high level of realism.
　また、本実施形態の電子機器１等によれば、振動子８０（１）を第１の周波数ｆ１で振動させ、振動子８０（４）を第１の周波数ｆ１とは異なる第２の周波数ｆ２で振動させる。これにより、電子機器１等によれば、振動定位の移動の軌跡ＬＣ１に沿って何らかの物体が移動したかのような強い印象をユーザに与えることができる。 Further, according to the electronic device 1 or the like of the present embodiment, the vibrator 80 (1) is vibrated at the first frequency f1, and the vibrator 80 (4) is second frequency f2 different from the first frequency f1. Vibrate with. Thereby, according to the electronic device 1 or the like, it is possible to give a strong impression to the user as if any object has moved along the locus LC1 of vibration localization movement.
　なお、上述した一例において、振動定位を位置Ｐｖ１から位置Ｐｖ２に移動させる際に、２つの振動子の振幅を変化させることにより、振動定位を制御する場合について説明したが、これに限られない。制御部９０は、３つまたは４つの振動子の振幅を同時に変化させることにより、振動定位を制御してもよい。また、振動定位の軌跡の変形例を図１０および図１１に示す。 In the above-described example, the case where the vibration localization is controlled by changing the amplitudes of the two vibrators when moving the vibration localization from the position Pv1 to the position Pv2 has been described. However, the present invention is not limited to this. The controller 90 may control the vibration localization by simultaneously changing the amplitudes of the three or four vibrators. Moreover, the modification of the locus | trajectory of a vibration localization is shown in FIG. 10 and FIG.
　図１０は、本実施形態の制御部９０が制御する振動定位の軌跡の第１の変形例を示す模式図である。制御部９０は、図１０に示すように、位置Ｐｖ３から位置Ｐｖ４まで、移動の軌跡ＬＣ２に沿って振動定位を移動させるようにして、振動定位を制御してもよい。この軌跡ＬＣ２とは、Ｘ方向において、振動子８０（１）と振動子８０（２）との間にある位置Ｐｖ３を移動の開始位置にする振動定位の軌跡である。また、この軌跡ＬＣ２とは、Ｘ方向において、振動子８０（３）と振動子８０（４）との間にある位置Ｐｖ４を移動の終了位置にする振動定位の軌跡である。この場合、制御部９０は、４つすべての振動子の振幅を制御して、位置Ｐｖ３または位置Ｐｖ４に振動を定位させる。このように、制御部９０は、複数の振動子の振幅を制御することにより、任意の位置に振動を定位させてもよい。電子機器１は、この軌跡ＬＣ２に沿って振動定位を移動させることにより、電子機器１が－Ｙ方向に移動するような印象をユーザに与えることができる。このとき、ユーザが、－Ｙ方向を重力方向（鉛直下方向）にして保持している場合には、電子機器１は、この電子機器１自体が重力方向に引っ張られているような印象をユーザに与えることができる。 FIG. 10 is a schematic diagram showing a first modified example of the locus of vibration localization controlled by the control unit 90 of the present embodiment. As shown in FIG. 10, the control unit 90 may control the vibration localization by moving the vibration localization along the movement locus LC2 from the position Pv3 to the position Pv4. The trajectory LC2 is a vibration localization trajectory in which the position Pv3 located between the vibrator 80 (1) and the vibrator 80 (2) is the start position of movement in the X direction. Further, the locus LC2 is a locus of vibration localization in which the position Pv4 between the transducer 80 (3) and the transducer 80 (4) is the end position of the movement in the X direction. In this case, the control unit 90 controls the amplitudes of all four vibrators to localize the vibration at the position Pv3 or the position Pv4. As described above, the control unit 90 may localize the vibration at an arbitrary position by controlling the amplitudes of the plurality of vibrators. The electronic device 1 can give the user an impression that the electronic device 1 moves in the −Y direction by moving the vibration localization along the locus LC2. At this time, when the user holds the −Y direction in the direction of gravity (vertically downward), the electronic device 1 gives an impression that the electronic device 1 itself is pulled in the direction of gravity. Can be given to.
　図１１は、本実施形態の制御部９０が制御する振動定位の軌跡の第２の変形例を示す模式図である。制御部９０は、図１１に示すように、ある位置から位置Ｐｖ５まで軌跡ＬＣ３－１に沿って振動定位を移動させ、さらに、位置Ｐｖ５から位置Ｐｖ６まで軌跡ＬＣ３－２に沿って振動定位を移動させるようにして、振動定位を制御してもよい。すなわち、制御部９０は、振動定位の位置（座標）を指定することによるだけでなく、振動定位の軌跡を指定することによっても、振動定位を制御することができる。また、制御部９０は、振動定位の軌跡を直線にするだけでなく、任意の曲線にして、振動定位を制御することができる。 FIG. 11 is a schematic diagram showing a second modified example of the locus of vibration localization controlled by the control unit 90 of the present embodiment. As shown in FIG. 11, the control unit 90 moves the vibration localization along the locus LC3-1 from a certain position to the position Pv5, and further moves the vibration localization along the locus LC3-2 from the position Pv5 to the position Pv6. In this manner, the vibration localization may be controlled. That is, the control unit 90 can control the vibration localization not only by designating the position (coordinates) of the vibration localization but also by designating the locus of the vibration localization. Further, the control unit 90 can control the vibration localization not only by making the locus of vibration localization a straight line but also by making an arbitrary curve.
［第２の実施形態］
　以下、図面を参照して、本発明の第２の実施形態を説明する。なお、上述した第１の実施形態と同様である構成及び動作については、同一の符号を付して、説明を簡略化あるいは省略する。本実施形態の電子機器１は、振動定位の座標をＸＹ平面内だけでなくＺ軸方向にも制御可能な点において、第１の実施形態と異なる。以下、本実施形態の制御部９０が振動定位を制御する構成について説明する。 [Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. In addition, about the structure and operation | movement similar to 1st Embodiment mentioned above, the same code | symbol is attached | subjected and description is simplified or abbreviate | omitted. The electronic device 1 according to the present embodiment is different from the first embodiment in that the coordinates of the vibration localization can be controlled not only in the XY plane but also in the Z-axis direction. Hereinafter, a configuration in which the control unit 90 of the present embodiment controls the vibration localization will be described.
　図１２は、本発明の第２の実施形態の制御部９０が制御する振動定位の軌跡を示す模式図である。制御部９０は、図１２に示すように、位置Ｐｖ７から位置Ｐｖ８まで軌跡ＬＣ４に沿って振動定位を移動させるようにして、振動定位を制御する。ここで、位置Ｐｖ７と、位置Ｐｖ８とは、Ｚ方向の座標が相違する位置である。つまり、制御部９０は、ＸＹＺ空間内において振動定位を制御する。この一例においては、位置Ｐｖ７とは、電子機器１のタッチパネル１０の奥側（－Ｚ方向）の位置である。また、位置Ｐｖ８とは、電子機器１のタッチパネル１０の手前側（＋Ｚ方向）の位置である。本実施形態の制御部９０は、振動定位の移動の軌跡が電子機器１の奥および手前方向である場合においても、振動定位を制御することができる。 FIG. 12 is a schematic diagram showing a locus of vibration localization controlled by the control unit 90 according to the second embodiment of the present invention. As shown in FIG. 12, the control unit 90 controls the vibration localization by moving the vibration localization along the locus LC4 from the position Pv7 to the position Pv8. Here, the position Pv7 and the position Pv8 are positions where the coordinates in the Z direction are different. That is, the control unit 90 controls the vibration localization in the XYZ space. In this example, the position Pv7 is a position on the back side (−Z direction) of the touch panel 10 of the electronic device 1. The position Pv8 is a position on the near side (+ Z direction) of the touch panel 10 of the electronic device 1. The control unit 90 according to the present embodiment can control the vibration localization even when the locus of movement of the vibration localization is the back and front directions of the electronic device 1.
　ここで、この具体例における、振動定位の移動の軌跡の奥側を示す振動子、および振動定位の移動の軌跡の手前側を示す振動子について説明する。この一例において、位置Ｐｖ７は、位置Ｐｖ８に対して－Ｚ方向（奥側）に位置する。すなわち、位置Ｐｖ７とは、振動定位の移動の軌跡ＬＣ４の奥側の位置である。ここで、位置Ｐｖ７は、位置Ｐｖ８に比べて振動子８０（１）および振動子８０（２）に近い位置にある。このため、位置Ｐｖ７に振動を定位させる場合に、振動子８０（１）および振動子８０（２）の振幅の寄与率が、振動子８０（３）および振動子８０（４）の振幅の寄与率よりも大きい。この場合、振動子８０（１）および振動子８０（２）が、振動定位の移動の軌跡の奥側を示す振動子である。 Here, the vibrator showing the back side of the locus of movement of the vibration localization and the vibrator showing the near side of the locus of movement of the vibration localization in this specific example will be described. In this example, the position Pv7 is located in the −Z direction (back side) with respect to the position Pv8. That is, the position Pv7 is a position on the far side of the locus LC4 of vibration localization movement. Here, the position Pv7 is closer to the vibrator 80 (1) and the vibrator 80 (2) than the position Pv8. For this reason, when the vibration is localized at the position Pv7, the contribution ratio of the amplitude of the vibrator 80 (1) and the vibrator 80 (2) is the contribution of the amplitude of the vibrator 80 (3) and the vibrator 80 (4). Greater than rate. In this case, the vibrator 80 (1) and the vibrator 80 (2) are vibrators that indicate the back side of the locus of movement of vibration localization.
　また、この一例において、位置Ｐｖ８は、位置Ｐｖ７に対して＋Ｚ方向（手前側）に位置する。すなわち、位置Ｐｖ８とは、振動定位の移動の軌跡ＬＣ４の手前側の位置である。ここで、位置Ｐｖ８は、位置Ｐｖ７に比べて振動子８０（３）および振動子８０（４）に近い位置にある。このため、位置Ｐｖ８に振動を定位させる場合に、振動子８０（３）および振動子８０（４）の振幅の寄与率が、振動子８０（１）および振動子８０（２）の振幅の寄与率よりも大きい。この場合、振動子８０（３）および振動子８０（４）が、振動定位の移動の軌跡の手前側を示す振動子である。次に、制御部９０がＺ方向に振動定位を制御する仕組みについて、図１３を参照して説明する。 In this example, the position Pv8 is located in the + Z direction (front side) with respect to the position Pv7. That is, the position Pv8 is a position on the near side of the locus LC4 of vibration localization movement. Here, the position Pv8 is closer to the vibrator 80 (3) and the vibrator 80 (4) than the position Pv7. Therefore, when the vibration is localized at the position Pv8, the contribution ratio of the amplitude of the vibrator 80 (3) and the vibrator 80 (4) is the contribution of the amplitude of the vibrator 80 (1) and the vibrator 80 (2). Greater than rate. In this case, the vibrator 80 (3) and the vibrator 80 (4) are vibrators that indicate the near side of the locus of movement of vibration localization. Next, a mechanism in which the control unit 90 controls the vibration localization in the Z direction will be described with reference to FIG.
　図１３は、本実施形態の制御部９０が出力する駆動信号の波形の一例を示すグラフである。この図１３の各グラフにおいて、横軸は時刻ｔを示し、縦軸は振動子の振動の振幅の大きさＡを示す。制御部９０は、上述の一例において、振動定位を位置Ｐｖ７から位置Ｐｖ８に移動させる場合に、図１３（Ａ）に示す波形Ｗ２Ａの駆動信号を振動子８０（３）および振動子８０（４）に出力する。また、この場合に、制御部９０は、図１３（Ｂ）に示す波形Ｗ２Ｂの駆動信号を振動子８０（１）および振動子８０（２）に出力する。ここで、時刻ｔ１から時刻ｔ５までの時間は、一例として２０００［ｍｓ］である。なお、この波形Ｗ２Ａおよび波形Ｗ２Ｂは、定位データ６４として記憶部６０に予め記憶されていてもよく、制御部９０の演算によって生成されてもよい。 FIG. 13 is a graph showing an example of the waveform of the drive signal output by the control unit 90 of the present embodiment. In each graph of FIG. 13, the horizontal axis indicates time t, and the vertical axis indicates the amplitude A of the vibration of the vibrator. In the above example, when the vibration localization is moved from the position Pv7 to the position Pv8, the control unit 90 transmits the drive signal of the waveform W2A shown in FIG. 13A to the vibrator 80 (3) and the vibrator 80 (4). Output to. In this case, the control unit 90 outputs a drive signal having a waveform W2B shown in FIG. 13B to the vibrator 80 (1) and the vibrator 80 (2). Here, the time from time t1 to time t5 is, for example, 2000 [ms]. The waveform W2A and the waveform W2B may be stored in advance in the storage unit 60 as the localization data 64, or may be generated by calculation of the control unit 90.
　この波形Ｗ２Ａとは、波形Ｗ２Ａの振幅の包絡線Ｅｎｖ２Ａが示すように、時刻ｔの経過とともに振幅が漸増する駆動信号の一例である。また、波形Ｗ２Ｂとは、波形Ｗ２Ｂの振幅の包絡線Ｅｎｖ２Ｂが示すように、時刻ｔの経過とともに振幅が漸減する駆動信号の一例である。制御部９０は、波形Ｗ２Ｂの駆動信号を振動子８０（１）および振動子８０（２）に供給することにより、これらの振動子の振動の振幅を漸減させる。また、制御部９０は、波形Ｗ２Ａの駆動信号を振動子８０（３）および振動子８０（４）に供給することにより、これらの振動子の振動の振幅を漸減させる。この制御部９０は、振動子８０（１）および振動子８０（２）を第１の周波数ｆ１で振動させ、振動子８０（３）および振動子８０（４）を第１の周波数ｆ１とは異なる第３の周波数ｆ３で振動させる。 This waveform W2A is an example of a drive signal whose amplitude gradually increases as time t passes, as indicated by the envelope Env2A of the amplitude of the waveform W2A. The waveform W2B is an example of a drive signal whose amplitude gradually decreases as time t passes, as indicated by the envelope Env2B of the amplitude of the waveform W2B. The controller 90 supplies the drive signal having the waveform W2B to the vibrator 80 (1) and the vibrator 80 (2), thereby gradually reducing the amplitude of vibration of these vibrators. Further, the control unit 90 supplies the drive signal having the waveform W2A to the vibrator 80 (3) and the vibrator 80 (4), thereby gradually reducing the amplitude of vibration of these vibrators. The controller 90 vibrates the vibrator 80 (1) and the vibrator 80 (2) at the first frequency f1, and the vibrator 80 (3) and the vibrator 80 (4) have the first frequency f1. Vibrates at a different third frequency f3.
　具体的には、波形Ｗ２Ａの周波数は、波形Ｗ２Ｂの周波数よりも高い。具体的には、波形Ｗ２Ａの周波数は１００［Ｈｚ］であり、波形Ｗ２Ｂの周波数は５０［Ｈｚ］である。
　なお、以下の説明において、波形Ｗ２Ｂの周波数を、比較の基準周波数としての第１の周波数ｆ１とも記載する。また、波形Ｗ２Ａの周波数を、第３の周波数ｆ３とも記載する。
　また、この一例においては、上述したように第１の周波数ｆ１は５０［Ｈｚ］であり、第３の周波数ｆ３は１００［Ｈｚ］である。すなわち、制御部９０は、振動子８０（１）および振動子８０（２）を第１の周波数ｆ１で振動させ、振動子８０（３）および振動子８０（４）を第１の周波数ｆ１よりも高い第３の周波数ｆ３で振動させる。 Specifically, the frequency of the waveform W2A is higher than the frequency of the waveform W2B. Specifically, the frequency of the waveform W2A is 100 [Hz], and the frequency of the waveform W2B is 50 [Hz].
In the following description, the frequency of the waveform W2B is also referred to as a first frequency f1 as a reference frequency for comparison. Further, the frequency of the waveform W2A is also referred to as a third frequency f3.
In this example, as described above, the first frequency f1 is 50 [Hz], and the third frequency f3 is 100 [Hz]. That is, the control unit 90 vibrates the vibrator 80 (1) and the vibrator 80 (2) at the first frequency f1, and causes the vibrator 80 (3) and the vibrator 80 (4) to vibrate from the first frequency f1. Is vibrated at a higher third frequency f3.
　ここで、電子機器１を保持するユーザの掌Ｐに振動が伝達される際に、振動の周波数が低い場合には、振動定位の座標が奥（－Ｚ）側にあるように感じられる。また、振動の周波数が高い場合には、ユーザが感じる振動定位の座標が手前（＋Ｚ）側にあるように感じられる。このため、制御部９０は、振動定位を軌跡ＬＣ４に沿って移動させる場合に、軌跡ＬＣ４の奥側における振動の周波数よりも、手前側における振動の周波数を高くする。
　これにより、電子機器１は、振動定位の移動の軌跡ＬＣ４に沿って、すなわち、電子機器１の奥側から手前側に、何らかの物体が移動したかのような強い印象をユーザに与えることができる。 Here, when the vibration is transmitted to the palm P of the user holding the electronic device 1, if the vibration frequency is low, it is felt that the vibration localization coordinates are on the back (−Z) side. Further, when the vibration frequency is high, it is felt that the vibration localization coordinates felt by the user are on the front (+ Z) side. For this reason, when moving the vibration localization along the trajectory LC4, the control unit 90 increases the frequency of the vibration on the near side to the frequency of the vibration on the far side of the trajectory LC4.
Thereby, the electronic device 1 can give a strong impression to the user as if some object has moved along the trajectory LC4 of the vibration localization movement, that is, from the back side to the near side of the electronic device 1. .
　また、制御部９０は、図１３（Ａ）に示す波形Ｗ２Ａの駆動信号を振動子８０（１）および振動子８０（２）に出力し、図１３（Ｂ）に示す波形Ｗ２Ｂの駆動信号を振動子８０（３）および振動子８０（４）に出力することもできる。この場合には、電子機器１は、軌跡ＬＣ４と逆向きに、この軌跡ＬＣ４に沿って、すなわち、電子機器１の手前側から奥側に、何らかの物体が移動したかのような強い印象をユーザに与えることができる。 Further, the control unit 90 outputs the drive signal having the waveform W2A shown in FIG. 13A to the vibrator 80 (1) and the vibrator 80 (2), and the drive signal having the waveform W2B shown in FIG. It is also possible to output to the vibrator 80 (3) and the vibrator 80 (4). In this case, the electronic device 1 gives a strong impression as if some object has moved along the locus LC4 in the opposite direction to the locus LC4, that is, from the near side to the far side of the electronic device 1. Can be given to.
　以上説明したように、制御部９０は、振動子８０（１）および振動子８０（２）を第１の周波数ｆ１で振動させ、振動子８０（３）および振動子８０（４）を第１の周波数ｆ１よりも高い第３の周波数ｆ３で振動させる。換言すれば、振動定位の移動の軌跡が電子機器１の奥側から手前方向である場合において、制御部９０は、振動定位の移動の軌跡の奥側を示す振動子として複数の振動子から選択される振動子を第１の周波数ｆ１によって振動させる。また、制御部９０は、振動定位の移動の軌跡の手前側を示す振動子として複数の振動子から選択される振動子を第１の周波数ｆ１よりも高い第３の周波数ｆ３によって振動させる。これにより、制御部９０は、振動定位を位置Ｐｖ７から位置Ｐｖ８に軌跡ＬＣ４に沿って移動させることができる。すなわち、制御部９０は、振動定位をＸＹＺ空間内において奥（－Ｚ）側から手前（＋Ｚ）側に移動させることができる。
　また、この例とは逆に、制御部９０は、振動定位の移動の軌跡の奥側を示す振動子として複数の振動子から選択される振動子を第１の周波数ｆ１よりも高い第３の周波数ｆ３によって振動させることもできる。また、制御部９０は、振動定位の移動の軌跡の手前側を示す振動子として複数の振動子から選択される振動子を第１の周波数ｆ１によって振動させることもできる。これにより、制御部９０は、振動定位を位置Ｐｖ８から位置Ｐｖ７に、すなわち軌跡ＬＣ４と逆向きに軌跡ＬＣ４に沿って移動させることができる。すなわち、制御部９０は、振動定位をＸＹＺ空間内において手前（＋Ｚ）側から奥（－Ｚ）側に移動させることができる。 As described above, the control unit 90 vibrates the vibrator 80 (1) and the vibrator 80 (2) at the first frequency f1, and causes the vibrator 80 (3) and the vibrator 80 (4) to be the first. Is oscillated at a third frequency f3 higher than the first frequency f1. In other words, when the locus of movement of the vibration localization is in the forward direction from the back side of the electronic device 1, the control unit 90 selects from a plurality of vibrators as the vibrator indicating the back side of the movement locus of the vibration localization. The vibrator to be vibrated is vibrated at the first frequency f1. Further, the control unit 90 vibrates a vibrator selected from a plurality of vibrators as a vibrator indicating the near side of the vibration localization movement locus at a third frequency f3 higher than the first frequency f1. Thereby, the control unit 90 can move the vibration localization from the position Pv7 to the position Pv8 along the locus LC4. That is, the control unit 90 can move the vibration localization from the back (−Z) side to the front (+ Z) side in the XYZ space.
Contrary to this example, the control unit 90 selects a third oscillator that is selected from a plurality of transducers as a transducer that indicates the back side of the locus of movement of vibration localization, and has a third frequency higher than the first frequency f1. It can also be vibrated by the frequency f3. The control unit 90 can also vibrate a vibrator selected from a plurality of vibrators with a first frequency f1 as a vibrator indicating the near side of the locus of movement of vibration localization. Accordingly, the control unit 90 can move the vibration localization from the position Pv8 to the position Pv7, that is, along the locus LC4 in the direction opposite to the locus LC4. That is, the control unit 90 can move the vibration localization from the front (+ Z) side to the back (−Z) side in the XYZ space.
　なお、この制御部９０は、上述した第１の実施形態による制御と、第２の実施形態による制御を組み合わせることによって、ＸＹＺ空間内の任意の座標に振動を定位させることができる。また、制御部９０は、上述した第１の実施形態による制御と、第２の実施形態による制御を組み合わせることによって、ＸＹＺ空間内の任意の軌跡に沿って振動定位を移動させることができる。 Note that the control unit 90 can localize vibrations at arbitrary coordinates in the XYZ space by combining the control according to the first embodiment and the control according to the second embodiment. In addition, the control unit 90 can move the vibration localization along an arbitrary locus in the XYZ space by combining the control according to the first embodiment and the control according to the second embodiment.
