　［再生速度の調節］
　第１調節部５２は、第１検出部３４２Ａによって検出される第１ダイヤル３４１Ａの回転状態に基づいて、第１楽曲の再生速度を調節する。具体的に、第１調節部５２は、第１検出部３４２Ａによる検出結果として、第１ダイヤル３４１Ａの回転方向、第１ダイヤル３４１Ａの回転加速度、及び、第１ダイヤル３４１Ａの回転角度を取得する。そして、第１調節部５２は、第１ダイヤル３４１Ａの回転加速度に基づいて第１ダイヤル３４１Ａの回転速度を算出し、第１ダイヤル３４１Ａの回転方向、回転速度及び回転角度に基づいて、第１楽曲のＢＰＭを調節して第１楽曲の再生速度を調節する。すなわち、第１調節部５２が第１楽曲の再生速度を調節するときに参照する第１ダイヤル３４１Ａの回転状態は、第１ダイヤル３４１Ａの回転速度を含む。 [Adjust playback speed]
The first adjuster 52 adjusts the playback speed of the first music based on the rotation state of the first dial 341A detected by the first detector 342A. Specifically, the first adjustment unit 52 acquires the rotation direction of the first dial 341A, the rotation acceleration of the first dial 341A, and the rotation angle of the first dial 341A as the detection results of the first detection unit 342A. Then, the first adjustment unit 52 calculates the rotation speed of the first dial 341A based on the rotation acceleration of the first dial 341A, and calculates the rotation speed of the first song based on the rotation direction, rotation speed and rotation angle of the first dial 341A. is adjusted to adjust the playback speed of the first music piece. That is, the rotational state of the first dial 341A referred to when the first adjustment unit 52 adjusts the reproduction speed of the first music includes the rotational speed of the first dial 341A.
　例えば、第１調節部５２は、天面２１に対向する位置から見て第１ダイヤル３４１Ａが時計回りに回転されると、第１調節部５２は、現在の第１楽曲の再生速度に対応するＢＰＭを増加させて、現在の第１楽曲の再生速度を増加させる。時計回りは、第１回転方向に相当する。
　一方、第１調節部５２は、天面２１に対向する位置から見て第１ダイヤル３４１Ａが反時計回りに回転されると、第１調節部５２は、現在の第１楽曲のＢＰＭを減少させて、現在の第１楽曲の再生速度を減少させる。反時計回りは、第１回転方向とは反対方向に相当する。 For example, when the first dial 341A is rotated clockwise when viewed from the position facing the top surface 21, the first adjustment unit 52 adjusts the playback speed of the current first music piece. The BPM is increased to increase the playback speed of the current first music piece. Clockwise corresponds to the first rotation direction.
On the other hand, when the first dial 341A is rotated counterclockwise when viewed from the position facing the top surface 21, the first adjustment unit 52 decreases the BPM of the current first music piece. to decrease the playback speed of the current first song. Counterclockwise corresponds to a direction opposite to the first rotation direction.
　また、第１調節部５２は、第１ダイヤル３４１Ａの回転速度及び回転角度に基づいて、第１楽曲の再生速度を変化させる。
　具体的に、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度未満である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲の再生速度の変化量を、第１変化量とする。すなわち、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度未満である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を、第１変化量とする。そして、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度未満である間、第１ダイヤル３４１Ａの回転角度が単位回転角度に達する毎に、現在の第１楽曲のＢＰＭに対して第１変化量を加算又は減算する。
　例えば、単位回転角度が３°であり、第１変化量が０．１である場合には、第１ダイヤル３４１Ａの回転速度が所定速度未満である間、第１調節部５２は、第１ダイヤル３４１Ａが３°回転される毎に、第１楽曲のＢＰＭを０．１ずつ加算又は減算する。このため、例えば上記所定速度未満の回転速度で第１ダイヤル３４１Ａを時計回りに９０°回転させた場合には、第１楽曲のＢＰＭは、第１ダイヤル３４１Ａが時計回りに９０°回転される前の第１楽曲のＢＰＭに３を加算した値となる。また例えば、上記所定速度未満の回転速度で第１ダイヤル３４１Ａを反時計回りに３０°回転させた場合には、第１楽曲のＢＰＭは、第１ダイヤル３４１Ａが反時計回りに３０°回転される前の第１楽曲のＢＰＭに１を減算した値となる。 Also, the first adjustment unit 52 changes the playback speed of the first music based on the rotation speed and rotation angle of the first dial 341A.
Specifically, while the rotation speed of first dial 341A is less than the predetermined speed, first adjustment unit 52 adjusts the amount of change in the playback speed of the first music piece for each unit rotation angle of first dial 341A to the first change. Quantity. That is, while the rotation speed of the first dial 341A is less than the predetermined speed, the first adjustment unit 52 sets the amount of change in the BPM of the first song for each unit rotation angle of the first dial 341A as the first amount of change. . While the rotation speed of the first dial 341A is less than the predetermined speed, the first adjustment unit 52 adjusts the current BPM of the first music every time the rotation angle of the first dial 341A reaches the unit rotation angle. Add or subtract the first change amount.
For example, when the unit rotation angle is 3° and the first change amount is 0.1, while the rotation speed of the first dial 341A is less than the predetermined speed, the first adjustment unit 52 rotates the first dial Each time 341A is rotated by 3°, the BPM of the first music is added or subtracted by 0.1. Therefore, for example, when the first dial 341A is rotated 90° clockwise at a rotation speed less than the predetermined speed, the BPM of the first music is 3 is added to the BPM of the first music piece. Further, for example, when the first dial 341A is rotated 30° counterclockwise at a rotational speed lower than the predetermined speed, the BPM of the first music is rotated 30° counterclockwise by the first dial 341A. It is a value obtained by subtracting 1 from the BPM of the previous first music piece.
　また、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度以上である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲の再生速度の変化量を、第１変化量よりも大きい第２変化量とする。すなわち、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度以上である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を、第２変化量とする。そして、第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度以上である間、第１ダイヤル３４１Ａの回転角度が単位回転角度に達する毎に、現在の第１楽曲のＢＰＭに対して第２変化量を加算又は減算する。
　例えば、単位回転角度が３°であり、第２変化量が１°である場合には、第１ダイヤル３４１Ａの回転速度が所定速度以上である間、第１調節部５２は、第１ダイヤル３４１Ａが３°回転される毎に、第１楽曲のＢＰＭを１ずつ加算又は減算する。このため、例えば上記所定速度以上の回転速度で第１ダイヤル３４１Ａを時計回りに９０°回転させた場合には、第１楽曲のＢＰＭは、第１ダイヤル３４１Ａが時計回りに９０°回転される前の第１楽曲のＢＰＭに３０を加算した値となる。また例えば、上記所定速度以上の回転速度で第１ダイヤル３４１Ａを反時計回りに３０°回転させた場合には、第１楽曲のＢＰＭは、第１ダイヤル３４１Ａが反時計回りに３０°回転される前の第１楽曲のＢＰＭに１０を減算した値となる。 Further, while the rotation speed of the first dial 341A is equal to or higher than the predetermined speed, the first adjustment unit 52 adjusts the amount of change in the reproduction speed of the first music piece for each unit rotation angle of the first dial 341A from the first amount of change. is also a large second amount of change. That is, while the rotation speed of the first dial 341A is equal to or higher than the predetermined speed, the first adjustment unit 52 sets the amount of change in the BPM of the first song for each unit rotation angle of the first dial 341A as the second amount of change. . While the rotation speed of the first dial 341A is equal to or higher than the predetermined speed, the first adjustment unit 52 adjusts the current BPM of the first music every time the rotation angle of the first dial 341A reaches the unit rotation angle. Add or subtract the second amount of change.
For example, when the unit rotation angle is 3° and the second amount of change is 1°, while the rotation speed of the first dial 341A is equal to or higher than the predetermined speed, the first adjustment unit 52 rotates the first dial 341A. is rotated by 3°, the BPM of the first music is added or subtracted by one. Therefore, for example, when the first dial 341A is rotated 90° clockwise at a rotation speed equal to or higher than the predetermined speed, the BPM of the first music is 30 is added to the BPM of the first music piece. Further, for example, when the first dial 341A is rotated 30° counterclockwise at a rotation speed equal to or higher than the predetermined speed, the BPM of the first music is rotated 30° counterclockwise by the first dial 341A. It is a value obtained by subtracting 10 from the BPM of the previous first music piece.
　図３は、第１楽曲の再生速度を調節するときの第１ダイヤル３４１Ａの回転操作を示す図である。
　このように、第１楽曲のＢＰＭの変化量及び第１楽曲の再生速度の変化量は、第１ダイヤル３４１Ａの回転速度に応じて変化する。このため、例えば図３に示すように、第１ダイヤル３４１Ａを回転角度αだけ回転させるときの第１ダイヤル３４１Ａの回転速度を所定速度未満とすることによって、単位回転角度当たりの第１楽曲のＢＰＭの変化量を第１変化量とすることができる。これにより、第１楽曲のＢＰＭを細かく変化させることができる。
　一方、第１ダイヤル３４１Ａを回転角度αだけ回転させるときの第１ダイヤル３４１Ａの回転速度を所定速度以上とすることによって、単位回転角度当たりの第１楽曲のＢＰＭの変化量を第２変化量とすることができる。これにより、第１楽曲のＢＰＭを大きく変化させることができる。
　このような楽曲の再生速度の調節は、第２調節部５５によっても同様に行われる。 FIG. 3 is a diagram showing a rotating operation of the first dial 341A when adjusting the playback speed of the first music piece.
Thus, the amount of change in the BPM of the first music piece and the amount of change in the playback speed of the first music piece change according to the rotation speed of the first dial 341A. For this reason, for example, as shown in FIG. 3, by setting the rotation speed of the first dial 341A to be less than a predetermined speed when the first dial 341A is rotated by the rotation angle α, the BPM of the first music piece per unit rotation angle is reduced. can be used as the first change amount. Thereby, the BPM of the first music can be finely changed.
On the other hand, by setting the rotation speed of the first dial 341A to be equal to or higher than a predetermined speed when the first dial 341A is rotated by the rotation angle α, the amount of change in the BPM of the first music piece per unit rotation angle is defined as the second amount of change. can do. Thereby, the BPM of the first music can be greatly changed.
Such adjustment of the playback speed of music is also performed by the second adjustment unit 55 in the same manner.
　［通知部によるユーザーへの通知］
　次に、通知部３４３によるユーザーへの通知について説明する。
　以下、第１制御部５３によって制御される第１通知部３４３Ａによるユーザーへの通知について説明する。すなわち、第１通知部３４３Ａによる第１ダイヤル３４１Ａの回動規制について説明する。なお、第２制御部５６によって制御される第２通知部３４３Ｂによるユーザーへの通知についても同様である。 [Notification to user by notification part]
Next, notification to the user by the notification unit 343 will be described.
Notification to the user by the first notification unit 343A controlled by the first control unit 53 will be described below. That is, rotation regulation of the first dial 341A by the first notification unit 343A will be described. The same applies to notification to the user by the second notification section 343B controlled by the second control section 56. FIG.
　なお、楽曲に固有のＢＰＭ、すなわち、再生速度が調節される前の楽曲のＢＰＭをオリジナルＢＰＭと称し、再生速度が調節された後の楽曲のＢＰＭを調節後ＢＰＭと称する。このため、第１楽曲に固有のＢＰＭを第１オリジナルＢＰＭと称し、第１調節部５２によって再生速度が調節された後の第１楽曲のＢＰＭを第１調節後ＢＰＭと称する。
　また、楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合を調節後割合と称する。すなわち、オリジナルＢＰＭに対する調節後ＢＰＭの割合を調節後割合と称する。このため、第１オリジナルＢＰＭに対する第１調節後ＢＰＭの割合を第１調節後割合とする。なお、調節後割合は、百分率（％）で示される値である。 Note that the BPM specific to the song, that is, the BPM of the song before the playback speed is adjusted is called the original BPM, and the BPM of the song after the playback speed is adjusted is called the adjusted BPM. For this reason, the BPM unique to the first music piece will be referred to as the first original BPM, and the BPM of the first music piece after the playback speed has been adjusted by the first adjustment unit 52 will be referred to as the first post-adjustment BPM.
Also, the ratio of the BPM of the song after adjusting the playback speed to the BPM specific to the song is referred to as the post-adjustment ratio. That is, the ratio of the adjusted BPM to the original BPM is called the adjusted ratio. Therefore, the ratio of the first adjusted BPM to the first original BPM is defined as the first adjusted ratio. In addition, the ratio after adjustment is a value shown in percentage (%).
　第１制御部５３は、上記のように第１ダイヤル３４１Ａが回動されて、第１楽曲のＢＰＭが増加されて、第１調節後割合が所定値に到達すると、第１通知部３４３Ａを動作させて、第１ダイヤル３４１Ａの同方向への更なる回動を規制する。すなわち、第１制御部５３は、第１調節後割合が所定値に到達すると、第１通知部３４３Ａによって、第１ダイヤル３４１Ａの同方向への更なる回動を規制する。このため、通知部３４３は、規制部ということができる。 When the first dial 341A is rotated as described above, the BPM of the first music is increased, and the first post-adjustment ratio reaches the predetermined value, the first control unit 53 operates the first notification unit 343A. to restrict further rotation of the first dial 341A in the same direction. That is, when the first post-adjustment ratio reaches the predetermined value, the first control unit 53 controls the further rotation of the first dial 341A in the same direction by the first notification unit 343A. Therefore, the notification unit 343 can be called a regulation unit.
　具体的に、第１ダイヤル３４１Ａが時計回りに回動されて、第１楽曲のＢＰＭが増加され、第１調節後割合が所定値である第１限界値に到達した場合に、第１制御部５３は、第１通知部３４３Ａにより、第１ダイヤル３４１Ａの時計回りへの更なる回動を規制する。これにより、第１調節後割合が第１限界値に到達したことがユーザーに通知される。第１通知部３４３Ａによる第１ダイヤル３４１Ａの時計回りへの回動が規制された状態から第１ダイヤル３４１Ａが反時計回りに回動されて、第１調節後割合が第１限界値未満になると、第１通知部３４３Ａによる規制は解除される。第１限界値としては、「２００％」が例示される。 Specifically, when the first dial 341A is rotated clockwise to increase the BPM of the first song and the first post-adjustment ratio reaches a first limit value, which is a predetermined value, the first control unit 53 regulates further clockwise rotation of the first dial 341A by the first notification portion 343A. This notifies the user that the first adjusted percentage has reached the first limit. When the first dial 341A is rotated counterclockwise from the state where the clockwise rotation of the first dial 341A by the first notification unit 343A is restricted, and the first post-adjustment ratio becomes less than the first limit value. , the restriction by the first notification unit 343A is cancelled. "200%" is exemplified as the first limit value.
　同様に、第１ダイヤル３４１Ａが反時計回りに回動されて、第１楽曲のＢＰＭが減少され、第１調節後割合が所定値である第２限界値に到達した場合に、第１制御部５３は、第１通知部３４３Ａにより、第１ダイヤル３４１Ａの反時計回りへの更なる回動を規制する。これにより、第１調節後割合が第２限界値に到達したことがユーザーに通知される。第１通知部３４３Ａによる第１ダイヤル３４１Ａの反時計回りへの回動が規制された状態から第１ダイヤル３４１Ａが時計回りに回動されて、第１調節後割合が第２限界値よりも大きくなると、第１通知部３４３Ａによる規制は解除される。第２限界値としては、「０％」が例示される。 Similarly, when the first dial 341A is rotated counterclockwise to decrease the BPM of the first song and the first post-adjustment ratio reaches a predetermined second limit value, the first control unit 53 regulates further counterclockwise rotation of the first dial 341A by the first notification portion 343A. This notifies the user that the first adjusted percentage has reached the second limit. The first dial 341A is rotated clockwise from the state in which the counterclockwise rotation of the first dial 341A by the first notification portion 343A is restricted, and the first post-adjustment ratio becomes greater than the second limit value. Then, the regulation by the first notification unit 343A is canceled. "0%" is exemplified as the second limit value.
　なお、第１通知部３４３Ａは、第１ダイヤル３４１Ａの回動の規制に代えて、或いは、第１ダイヤル３４１Ａの回動の規制に加えて、他の方法によって、第１調節後割合が第１限界値又は第２限界値に到達したことを、ユーザーに通知してもよい。例えば、第１通知部３４３Ａは、通知音を出力してもよく、第１ダイヤル３４１Ａを振動させてもよい。 Note that the first notification unit 343A, instead of restricting the rotation of the first dial 341A, or in addition to restricting the rotation of the first dial 341A, sets the post-first adjustment ratio to the first The user may be notified that the limit or the second limit has been reached. For example, the first notification unit 343A may output a notification sound or vibrate the first dial 341A.

　次に、表示部３４４による表示内容を表示モード毎に説明する。
　モード切替部５７によって切り替えられる表示モードには、直接表示モード、割合表示モード、図形表示モード及びスライダー表示モードが含まれる。以下の説明では、第１表示部３４４Ａによる表示内容を説明するが、第２表示部３４４Ｂによる表示内容も同様である。 [Contents displayed on the display]
Next, the contents displayed by the display unit 344 will be described for each display mode.
The display modes switched by the mode switching unit 57 include a direct display mode, a ratio display mode, a graphics display mode, and a slider display mode. In the following description, the contents displayed by the first display section 344A will be described, but the same applies to the contents displayed by the second display section 344B.
　［直接表示モード］
　図４は、直接表示モードでの第１表示部３４４Ａの表示内容の一例を示す図である。
　直接表示モードは、図４に示すように、第１表示部３４４Ａが第１オリジナルＢＰＭと第１調節後ＢＰＭを表示する表示モードである。すなわち、直接表示モードでは、表示制御部５８は、第１オリジナルＢＰＭと第１調節後ＢＰＭとを第１表示部３４４Ａに表示させる。このため、直接表示モードにて第１表示部３４４Ａに表示される画面ＤＰ１には、第１オリジナルＢＰＭを表示するオリジナルＢＰＭ表示部ＤＰ１１と、第１調節後ＢＰＭを表示する調節後ＢＰＭ表示部ＤＰ１２と、が設けられている。 [Direct display mode]
FIG. 4 is a diagram showing an example of the display contents of the first display section 344A in the direct display mode.
The direct display mode is a display mode in which the first display unit 344A displays the first original BPM and the first adjusted BPM, as shown in FIG. That is, in the direct display mode, the display control unit 58 causes the first display unit 344A to display the first original BPM and the first adjusted BPM. Therefore, the screen DP1 displayed on the first display unit 344A in the direct display mode includes an original BPM display portion DP11 that displays the first original BPM and an adjusted BPM display portion DP12 that displays the first adjusted BPM. and is provided.
　［割合表示モード］
　図５は、割合表示モードでの第１表示部３４４Ａの表示内容の一例を示す図である。
　割合表示モードは、図５に示すように、第１表示部３４４Ａが第１オリジナルＢＰＭと、第１オリジナルＢＰＭに対する第１調節後ＢＰＭの割合（第１調節後割合）とを表示する表示モードである。すなわち、割合表示モードでは、表示制御部５８は、第１オリジナルＢＰＭと、第１調節後割合とを第１表示部３４４Ａに表示させる。このため、割合表示モードにて第１表示部３４４Ａに表示される画面ＤＰ２には、オリジナルＢＰＭ表示部ＤＰ１１と、第１調節後割合を表示する割合表示部ＤＰ２２と、が設けられている。なお、割合表示モードにて表示される割合は、楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合を示す情報の一例である。 [Ratio display mode]
FIG. 5 is a diagram showing an example of display contents of the first display section 344A in the ratio display mode.
The ratio display mode is a display mode in which the first display unit 344A displays the first original BPM and the ratio of the first adjusted BPM to the first original BPM (first adjusted ratio), as shown in FIG. be. That is, in the ratio display mode, the display control unit 58 causes the first display unit 344A to display the first original BPM and the first post-adjustment ratio. Therefore, the screen DP2 displayed on the first display portion 344A in the ratio display mode is provided with an original BPM display portion DP11 and a ratio display portion DP22 for displaying the first adjusted ratio. Note that the ratio displayed in the ratio display mode is an example of information indicating the ratio of the BPM of the song after the playback speed adjustment to the BPM specific to the song.
　［図形表示モード］
　図６は、図形表示モードでの第１表示部３４４Ａの表示内容の一例を示す図である。
　図形表示モードは、図６に示すように、第１表示部３４４Ａが第１オリジナルＢＰＭと、図形ＦＧ１，ＦＧ２のうち一方の図形と、を表示する表示モードである。図形ＦＧ１，ＦＧ２は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの比較結果に応じた図形である。詳述すると、図形ＦＧ１，ＦＧ２は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの大小関係を示す図形であり、図形ＦＧ１は、上向きの三角形であり、図形ＦＧ２は、下向きの三角形である。
　このため、図形表示モードにて第１表示部３４４Ａに表示される画面ＤＰ３には、オリジナルＢＰＭ表示部ＤＰ１１と、図形ＦＧ１，ＦＧ２を表示する図形表示部ＤＰ３１と、が設けられている。 [Graphic display mode]
FIG. 6 is a diagram showing an example of display contents of the first display section 344A in the graphics display mode.
The graphics display mode is a display mode in which the first display unit 344A displays the first original BPM and one of the graphics FG1 and FG2, as shown in FIG. Figures FG1 and FG2 are figures according to the result of comparison between the first original BPM and the first adjusted BPM. More specifically, the figures FG1 and FG2 are figures showing the magnitude relationship between the first original BPM and the first adjusted BPM, the figure FG1 being an upward triangle and the figure FG2 being a downward triangle.
Therefore, the screen DP3 displayed on the first display section 344A in the graphic display mode is provided with an original BPM display section DP11 and a graphic display section DP31 for displaying the graphics FG1 and FG2.
　［第１調節後ＢＰＭが第１オリジナルＢＰＭよりも大きい場合］
　図７は、第１調節後割合と、表示される図形ＦＧ１，ＦＧ２との関係を説明する図である。
　図形表示モードでは、第１調節後ＢＰＭが第１オリジナルＢＰＭよりも大きい場合、表示制御部５８は、図７に示すように、図形ＦＧ１を第１表示部３４４Ａに表示させ、図形ＦＧ２を表示させない。すなわち、図形ＦＧ１は、第１調節後ＢＰＭが第１オリジナルＢＰＭよりも大きいことを示す図形である。
　このとき、第１調節後割合が１００％より大きく、第１閾値未満である場合には、表示制御部５８は、第１表示部３４４Ａに表示される図形ＦＧ１の輝度を最も低くする。なお、第１閾値は、１００％よりも大きい値であり、本実施形態では１１０％である。しかしながら、第１閾値は、適宜変更可能である。 [When the first adjusted BPM is greater than the first original BPM]
FIG. 7 is a diagram for explaining the relationship between the first post-adjustment ratio and the displayed graphics FG1 and FG2.
In the graphic display mode, when the first adjusted BPM is greater than the first original BPM, the display control unit 58 causes the first display unit 344A to display the graphic FG1 and not display the graphic FG2, as shown in FIG. . That is, the graphic FG1 is a graphic indicating that the first adjusted BPM is greater than the first original BPM.
At this time, if the first post-adjustment ratio is greater than 100% and less than the first threshold, the display control unit 58 makes the brightness of the graphic FG1 displayed on the first display unit 344A the lowest. Note that the first threshold is a value greater than 100%, and is 110% in this embodiment. However, the first threshold can be changed as appropriate.
　また、第１調節後割合が第１閾値以上、第２閾値未満である場合には、表示制御部５８は、第１表示部３４４Ａに表示される図形ＦＧ１の輝度を高くする。すなわち、第１調節後割合が第１閾値以上、第２閾値未満である場合に表示される図形ＦＧ１の輝度は、第１調節後割合が１００％より大きく、第１閾値未満である場合に表示される図形ＦＧ１の輝度よりも高い。なお、第２閾値は、第１閾値よりも大きい値であり、本実施形態では、第２閾値は１２０％である。しかしながら、第２閾値は、適宜変更可能である。
　更に、第１調節後割合が第２閾値以上である場合には、表示制御部５８は、第１表示部３４４Ａに表示される図形ＦＧ１の輝度を最も高くする。
　すなわち、第１調節後割合が１００％よりも大きい場合に表示される図形ＦＧ１の輝度は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの差分が大きくなるに従って高くなり、第１オリジナルＢＰＭと第１調節後ＢＰＭとの差分が小さくなるに従って低くなる。換言すると、図形ＦＧ１の輝度は、第１調節後ＢＰＭが第１オリジナルＢＰＭに近づくに従って低くなり、第１調節後ＢＰＭが第１オリジナルＢＰＭから離れるに従って高くなる。
　このような図形ＦＧ１の輝度の違いは、楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合を示す情報の一例である。 Further, when the first post-adjustment ratio is greater than or equal to the first threshold and less than the second threshold, the display control unit 58 increases the brightness of the graphic FG1 displayed on the first display unit 344A. That is, the brightness of the graphic FG1 displayed when the first post-adjustment ratio is greater than or equal to the first threshold and less than the second threshold is displayed when the first post-adjustment ratio is greater than 100% and less than the first threshold. higher than the brightness of the figure FG1 to be displayed. Note that the second threshold is a value larger than the first threshold, and in this embodiment, the second threshold is 120%. However, the second threshold can be changed as appropriate.
Furthermore, when the first post-adjustment ratio is equal to or greater than the second threshold, the display control unit 58 maximizes the brightness of the graphic FG1 displayed on the first display unit 344A.
That is, the brightness of the graphic FG1 displayed when the first post-adjustment ratio is greater than 100% increases as the difference between the first original BPM and the first post-adjustment BPM increases. It becomes lower as the difference from the BPM after 1 adjustment becomes smaller. In other words, the brightness of the graphic FG1 decreases as the first adjusted BPM approaches the first original BPM, and increases as the first adjusted BPM separates from the first original BPM.
Such a difference in luminance of the graphic FG1 is an example of information indicating the ratio of the BPM of the song after the playback speed adjustment to the BPM specific to the song.
　［第１調節後ＢＰＭが第１オリジナルＢＰＭよりも小さい場合］
　図形表示モードでは、第１調節後ＢＰＭが第１オリジナルＢＰＭよりも小さい場合、表示制御部５８は、下向きの三角形である図形ＦＧ２を第１表示部３４４Ａに表示させ、上向きの三角形である図形ＦＧ１を表示させない。すなわち、図形ＦＧ２は、第１調節後ＢＰＭが第１オリジナルＢＰＭよりも小さいことを示す図形である。
　このとき、第１調節後割合が第３閾値よりも大きく、１００％未満である場合には、表示制御部５８は、図形ＦＧ２の輝度を最も低くする。第３閾値は、１００％よりも小さい値であり、本実施形態では９０％である。しかしながら、第３閾値は、適宜変更可能である。 [When the first adjusted BPM is smaller than the first original BPM]
In the graphic display mode, when the first adjusted BPM is smaller than the first original BPM, the display control unit 58 causes the first display unit 344A to display the downward triangular graphic FG2 and the upward triangular graphic FG1. is not displayed. That is, the graphic FG2 is a graphic showing that the first adjusted BPM is smaller than the first original BPM.
At this time, if the first post-adjustment ratio is greater than the third threshold and less than 100%, the display control unit 58 sets the brightness of the graphic FG2 to the lowest. The third threshold is a value smaller than 100%, and is 90% in this embodiment. However, the third threshold can be changed as appropriate.
　また、第１調節後割合が第３閾値以下であり、第４閾値よりも大きい場合には、表示制御部５８は、図形ＦＧ２の輝度を高くする。すなわち、第１調節後割合が第４閾値よりも大きく、第３閾値以下である場合に表示される図形ＦＧ２の輝度は、第１調節後割合が第３閾値よりも大きく、１００％未満である場合に表示される図形ＦＧ２の輝度よりも高い。なお、第４閾値は、第３閾値よりも小さい値であり、本実施形態では８０％である。しかしながら、第４閾値は、適宜変更可能である。
　更に、第１調節後割合が第４閾値以下である場合には、表示制御部５８は、図形ＦＧ２の輝度を最も高くする。
　すなわち、第１調節後割合が１００％よりも小さい場合に表示される図形ＦＧ２の輝度は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの差分が大きくなるに従って高くなり、第１オリジナルＢＰＭと第１調節後ＢＰＭとの差分が小さくなるに従って低くなる。換言すると、図形ＦＧ２の輝度は、第１調節後ＢＰＭが第１オリジナルＢＰＭに近づくに従って低くなり、第１調節後ＢＰＭが第１オリジナルＢＰＭから離れるに従って高くなる。
　このような図形ＦＧ２の輝度の違いは、楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合を示す情報の一例である。 Further, when the first post-adjustment ratio is equal to or less than the third threshold and greater than the fourth threshold, the display control unit 58 increases the brightness of the graphic FG2. That is, the luminance of the graphic FG2 displayed when the first post-adjustment ratio is greater than the fourth threshold and equal to or less than the third threshold is such that the first post-adjustment ratio is greater than the third threshold and less than 100%. is higher than the brightness of the graphic FG2 displayed in the case. Note that the fourth threshold is a value smaller than the third threshold, and is 80% in this embodiment. However, the fourth threshold can be changed as appropriate.
Furthermore, when the first post-adjustment ratio is equal to or less than the fourth threshold, the display control unit 58 sets the brightness of the graphic FG2 to the highest.
That is, the luminance of the graphic FG2 displayed when the first post-adjustment ratio is less than 100% increases as the difference between the first original BPM and the first post-adjustment BPM increases. It becomes lower as the difference from the BPM after 1 adjustment becomes smaller. In other words, the brightness of the graphic FG2 decreases as the first adjusted BPM approaches the first original BPM, and increases as the first adjusted BPM separates from the first original BPM.
Such a difference in brightness of the graphic FG2 is an example of information indicating the ratio of the BPM of the song after the playback speed adjustment to the BPM specific to the song.
　［第１調節後ＢＰＭが第１オリジナルＢＰＭと同じ値である場合］
　第１調節後ＢＰＭが第１オリジナルＢＰＭと同じ値である場合には、図７に示すように、図形ＦＧ１，ＦＧ２は表示されない。
　以上のように、図形ＦＧ１が表示される場合と、図形ＦＧ２が表示される場合と、図形ＦＧ１，ＦＧ２のそれぞれが表示されない場合とを確認することによって、ユーザーは、第１オリジナルＢＰＭに対する第１調節後ＢＰＭの大小を直感的に把握できる。この他、第１調節後割合を直感的に把握できる。 [When the first adjusted BPM is the same value as the first original BPM]
When the first adjusted BPM is the same value as the first original BPM, the graphics FG1 and FG2 are not displayed as shown in FIG.
As described above, by confirming the case where the figure FG1 is displayed, the case where the figure FG2 is displayed, and the case where each of the figures FG1 and FG2 is not displayed, the user can determine the first BPM for the first original BPM. The magnitude of the post-adjustment BPM can be intuitively grasped. In addition, the first post-adjustment ratio can be intuitively grasped.
　本実施形態では、図形ＦＧ１，ＦＧ２の輝度は、オリジナルＢＰＭと調節後ＢＰＭとの差分が大きくなるに従って高くなる。換言すると、図形ＦＧ１，ＦＧ２の輝度は、調節後ＢＰＭがオリジナルＢＰＭに近づくに従って低くなる。これにより、調節後ＢＰＭがオリジナルＢＰＭから離れた値であることを、ユーザーが把握しやすくすることができる。
　一方、図形ＦＧ１，ＦＧ２の輝度は、オリジナルＢＰＭと調節後ＢＰＭとの差分が小さくなるに従って高くなり、オリジナルＢＰＭと調節後ＢＰＭとの差分が大きくなるに従って低くなってもよい。具体的に、第１調節後割合が１００％よりも大きい場合に表示される図形ＦＧ１の輝度を、第１調節後割合が第１閾値よりも小さい場合に最も高くし、第１調節後割合が第２閾値以上である場合に最も低くしてもよい。同様に、第１調節後割合が１００％よりも小さい場合に表示される図形ＦＧ２の輝度を、第１調節後割合が第３閾値よりも大きい場合に最も高くし、第１調節後割合が第４閾値以下である場合に最も低くしてもよい。この場合、第１オリジナルＢＰＭと第１調節後ＢＰＭとが一致している状態から、第１オリジナルＢＰＭと第１調節後ＢＰＭとの差分が生じた場合に、図形ＦＧ１又は図形ＦＧ２が高い輝度で表示されるので、第１オリジナルＢＰＭと第１調節後ＢＰＭとが一致しているか否かを、ユーザーが判別しやすくすることができる。 In this embodiment, the brightness of the graphics FG1 and FG2 increases as the difference between the original BPM and the adjusted BPM increases. In other words, the brightness of the graphics FG1 and FG2 decreases as the adjusted BPM approaches the original BPM. This makes it easier for the user to grasp that the adjusted BPM is a value that is different from the original BPM.
On the other hand, the brightness of the graphics FG1 and FG2 may increase as the difference between the original BPM and the adjusted BPM decreases, and decrease as the difference between the original BPM and the adjusted BPM increases. Specifically, the luminance of the graphic FG1 displayed when the first post-adjustment ratio is greater than 100% is maximized when the first post-adjustment ratio is smaller than the first threshold, It may be the lowest when it is equal to or greater than the second threshold. Similarly, the brightness of the graphic FG2 displayed when the first post-adjustment ratio is less than 100% is maximized when the first post-adjustment ratio is greater than the third threshold, and when the first post-adjustment ratio is the third It may be the lowest if it is equal to or less than 4 thresholds. In this case, when a difference occurs between the first original BPM and the first adjusted BPM from the state in which the first original BPM and the first adjusted BPM match, the figure FG1 or the figure FG2 appears with high luminance. Since it is displayed, the user can easily determine whether or not the first original BPM and the first adjusted BPM match.

　図８は、スライダー表示モードでの第１表示部３４４Ａによる表示内容の一例を示す図である。
　スライダー表示モードは、図８に示すように、第１表示部３４４Ａが第１オリジナルＢＰＭと、第１オリジナルＢＰＭと第１調節後ＢＰＭとの比較結果に応じた図形として、図形ＦＧ３を表示する表示モードである。図形ＦＧ３は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの比較結果に応じた図形である。詳述すると、図形ＦＧ３は、第１オリジナルＢＰＭと第１調節後ＢＰＭとの大小関係を示す図形である。
　スライダー表示モードにて第１表示部３４４Ａに表示される画面ＤＰ４には、オリジナルＢＰＭ表示部ＤＰ１１と、図形ＦＧ３を表示する図形表示部ＤＰ４１と、が設けられている。 [Slider display mode]
FIG. 8 is a diagram showing an example of the content displayed by the first display section 344A in the slider display mode.
In the slider display mode, as shown in FIG. 8, the first display unit 344A displays a graphic FG3 as a graphic corresponding to the result of comparison between the first original BPM and the first adjusted BPM. mode. A graphic FG3 is a graphic corresponding to the comparison result between the first original BPM and the first adjusted BPM. More specifically, the graphic FG3 is a graphic showing the magnitude relationship between the first original BPM and the first post-adjustment BPM.
A screen DP4 displayed on the first display portion 344A in the slider display mode is provided with an original BPM display portion DP11 and a graphic display portion DP41 for displaying a graphic FG3.
　図形ＦＧ３は、所定のスライド範囲内において第１調節後割合に応じた位置にスライド操作子が配置されたスライダーを示す図形である。詳述すると、図形ＦＧ３は、第１基準線ＦＧ３１、第２基準線ＦＧ３２、スライド操作子ＦＧ３３及び範囲表示部ＦＧ３４を備える。すなわち、図形ＦＧ３は、テンポスライダーを模した図形である。
　第１基準線ＦＧ３１は、上下方向に延出する直線である。第１基準線ＦＧ３１によってスライド操作子ＦＧ３３のスライド範囲が規定される。
　第２基準線ＦＧ３２は、第１基準線ＦＧ３１の中央にて、第１基準線ＦＧ３１に交差する方向に延出している。第２基準線ＦＧ３２は「１００％」を示す目盛である。 A graphic FG3 is a graphic showing a slider in which a slide operator is arranged at a position corresponding to the first post-adjustment ratio within a predetermined slide range. Specifically, the graphic FG3 has a first reference line FG31, a second reference line FG32, a slide operator FG33, and a range display portion FG34. That is, the graphic FG3 is a graphic imitating a tempo slider.
The first reference line FG31 is a straight line extending vertically. The slide range of the slide operator FG33 is defined by the first reference line FG31.
The second reference line FG32 extends in a direction intersecting the first reference line FG31 at the center of the first reference line FG31. The second reference line FG32 is a scale indicating "100%".
　スライド操作子ＦＧ３３は、第１基準線ＦＧ３１に沿って上下にスライドし、第１調節後割合を示す。
　第１調節後割合が１００％である場合、すなわち、第１オリジナルＢＰＭと第１調節後ＢＰＭとが同じ値である場合には、スライド操作子ＦＧ３３は、表示制御部５８によって第２基準線ＦＧ３２上に配置される。
　第１オリジナルＢＰＭよりも第１調節後ＢＰＭが小さい場合には、スライド操作子ＦＧ３３は、表示制御部５８によって、第２基準線ＦＧ３２よりも上側に配置される。
　第１オリジナルＢＰＭよりも第１調節後ＢＰＭが大きい場合には、スライド操作子ＦＧ３３は、表示制御部５８によって、第２基準線ＦＧ３２よりも下側に配置される。
　このように、第２基準線ＦＧ３２に対するスライド操作子ＦＧ３３の位置によって、第１オリジナルＢＰＭと第１調節後ＢＰＭとの大小関係が示される。この点で、図形ＦＧ３は、上記のように、第１オリジナルＢＰＭと第１調節後ＢＰＭとの大小関係を示す図形である。 The slide operator FG33 slides up and down along the first reference line FG31 to indicate the first post-adjustment ratio.
When the first post-adjustment ratio is 100%, that is, when the first original BPM and the first post-adjustment BPM are the same value, the slide operator FG33 is moved by the display control unit 58 to the second reference line FG32. placed above.
When the first adjusted BPM is smaller than the first original BPM, the display control unit 58 arranges the slide operator FG33 above the second reference line FG32.
When the first adjusted BPM is higher than the first original BPM, the display control unit 58 arranges the slide operator FG33 below the second reference line FG32.
Thus, the position of the slide operator FG33 with respect to the second reference line FG32 indicates the magnitude relationship between the first original BPM and the first adjusted BPM. In this respect, the graphic FG3 is a graphic showing the magnitude relationship between the first original BPM and the first adjusted BPM, as described above.
　範囲表示部ＦＧ３４は、第１基準線ＦＧ３１上にスライド可能に配置されたスライド操作子ＦＧ３３によって示される第１調節後割合の範囲を表示する。
　ここで、第１基準線ＦＧ３１上に配置されたスライド操作子ＦＧ３３によって示される第１調節後割合の範囲は、第１調節後割合に応じて変更される。すなわち、第１基準線ＦＧ３１の上端によって規定される最小値と、第１基準線ＦＧ３１の下端によって規定される最大値とは、第１調節後割合に応じて変更される。 The range display portion FG34 displays the range of the first post-adjustment ratio indicated by the slide operator FG33 slidably arranged on the first reference line FG31.
Here, the range of the first post-adjustment ratio indicated by the slide operator FG33 arranged on the first reference line FG31 is changed according to the first post-adjustment ratio. That is, the minimum value defined by the upper end of the first reference line FG31 and the maximum value defined by the lower end of the first reference line FG31 are changed according to the first post-adjustment ratio.
　具体的に、第１調節後割合が、９４％以上、１０６％以下の範囲内の値である場合には、表示制御部５８は、第１基準線ＦＧ３１によって規定される第１調節後割合の範囲を、９４％以上、１０６％以下の範囲とする。このとき、第１基準線ＦＧ３１の上端によって規定される最小値は９４％であり、第１基準線ＦＧ３１の下端によって規定される最大値は１０６％である。この場合、範囲表示部ＦＧ３４には「６％」が表示される。 Specifically, when the first post-adjustment ratio is a value within the range of 94% or more and 106% or less, the display control unit 58 sets the first post-adjustment ratio defined by the first reference line FG31. Let the range be 94% or more and 106% or less. At this time, the minimum value defined by the upper end of the first reference line FG31 is 94%, and the maximum value defined by the lower end of the first reference line FG31 is 106%. In this case, "6%" is displayed in the range display portion FG34.
　第１調節後割合が、９０％以上、９４％未満の範囲内の値である場合、又は、１０６％より大きく、１１０％以下の範囲内の値である場合には、表示制御部５８は、第１基準線ＦＧ３１によって規定される第１調節後割合の範囲を、９０％以上、１１０％以下の範囲とする。このとき、第１基準線ＦＧ３１の上端によって規定される最小値は９０％であり、第１基準線ＦＧ３１の下端によって規定される最大値は１１０％である。この場合、範囲表示部ＦＧ３４には「１０％」が表示される。 If the first post-adjustment ratio is a value within the range of 90% or more and less than 94%, or is a value within the range of greater than 106% and 110% or less, the display control unit 58 Let the range of the first post-adjustment ratio defined by the first reference line FG31 be the range of 90% or more and 110% or less. At this time, the minimum value defined by the upper end of the first reference line FG31 is 90%, and the maximum value defined by the lower end of the first reference line FG31 is 110%. In this case, "10%" is displayed in the range display portion FG34.
　第１調節後割合が、８４％以上、９０％未満の範囲内の値である場合、又は、１１０％より大きく、１１６％以下の範囲内の値である場合には、表示制御部５８は、第１基準線ＦＧ３１によって規定される第１調節後割合の範囲を、８４％以上、１１６％以下の範囲とする。このとき、第１基準線ＦＧ３１の上端によって規定される最小値は８４％であり、第１基準線ＦＧ３１の下端によって規定される最大値は１１６％である。この場合、範囲表示部ＦＧ３４には「１６％」が表示される。 When the first post-adjustment ratio is a value within the range of 84% or more and less than 90%, or a value within the range of 110% or more and 116% or less, the display control unit 58 Let the range of the first post-adjustment ratio defined by the first reference line FG31 be the range of 84% or more and 116% or less. At this time, the minimum value defined by the upper end of the first reference line FG31 is 84%, and the maximum value defined by the lower end of the first reference line FG31 is 116%.

　なお、第１調節後割合が２００％よりも大きい場合には、表示制御部５８は、図形ＦＧ３に代えてエラーを示す図形を図形表示部ＤＰ４１に表示してもよい。 When the first post-adjustment ratio is a value within the range of 0% or more and less than 84%, or a value within the range of 116% or more and 200% or less, the display control unit 58 Let the range of the first post-adjustment ratio defined by the first reference line FG31 be the range of 0% or more and 200% or less.

In this case, "100%" is displayed in the range display portion FG34.
Note that when the first post-adjustment ratio is greater than 200%, the display control unit 58 may display a graphic indicating an error on the graphic display unit DP41 instead of the graphic FG3.
　このように、第１基準線ＦＧ３１上を第１調節後割合に応じてスライドするスライド操作子ＦＧ３３の位置と、範囲表示部ＦＧ３４に表示された範囲とを確認することによって、第１オリジナルＢＰＭと第１調節後ＢＰＭとの大小関係、並びに、第１調節後割合を直感的に把握できる。すなわち、図形ＦＧ３によって示される情報は、楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合を示す情報の一例である。 In this way, by confirming the position of the slide operator FG33 that slides on the first reference line FG31 according to the first post-adjustment ratio and the range displayed in the range display section FG34, the first original BPM and the The magnitude relationship with the first post-adjustment BPM and the first post-adjustment ratio can be intuitively grasped. That is, the information indicated by the graphic FG3 is an example of information indicating the ratio of the BPM of the song after the playback speed adjustment to the BPM specific to the song.
　［第１実施形態の効果］
　以上説明した本実施形態に係る音響制御装置１は、以下の効果を奏する。
　音響制御装置１は、楽曲の再生速度を調節可能な音響制御装置である。音響制御装置１は、第１ダイヤル３４１Ａ、第２ダイヤル３４１Ｂ及び制御部５を備える。第１ダイヤル３４１Ａ及び第２ダイヤル３４１Ｂは、筐体２に回転可能に設けられたダイヤルである。第１ダイヤル３４１Ａは、第１楽曲の再生速度を調整する操作を受け付け、第２ダイヤル３４１Ｂは、第２楽曲の再生速度を調整する操作を受け付ける。制御部５は、第１調節部５２及び第２調節部５５を備える。第１調節部５２は、第１ダイヤル３４１Ａの回転状態に応じて、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲の再生速度の変化量を変化させる。第２調節部５５は、第２ダイヤル３４１Ｂの回転状態に応じて、第２ダイヤル３４１Ｂの単位回転角度毎の第２楽曲の再生速度の変化量を変化させる。詳述すると、第１調節部５２は、第１ダイヤル３４１Ａの回転状態に応じて、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を変化させる。第２調節部５５は、第２ダイヤル３４１Ｂの回転状態に応じて、第２ダイヤル３４１Ｂの単位回転角度毎の第２楽曲のＢＰＭの変化量を変化させる。 [Effect of the first embodiment]
The acoustic control device 1 according to the present embodiment described above has the following effects.
The sound control device 1 is a sound control device capable of adjusting the reproduction speed of music. The acoustic control device 1 includes a first dial 341A, a second dial 341B and a control section 5. As shown in FIG. The first dial 341A and the second dial 341B are dials provided rotatably on the housing 2 . The first dial 341A receives an operation for adjusting the reproduction speed of the first music, and the second dial 341B receives an operation for adjusting the reproduction speed of the second music. The controller 5 includes a first adjuster 52 and a second adjuster 55 . The first adjustment unit 52 changes the amount of change in the reproduction speed of the first music piece for each unit rotation angle of the first dial 341A according to the rotation state of the first dial 341A. The second adjustment unit 55 changes the amount of change in the reproduction speed of the second music piece for each unit rotation angle of the second dial 341B according to the rotation state of the second dial 341B. More specifically, the first adjuster 52 changes the amount of change in the BPM of the first song for each unit rotation angle of the first dial 341A according to the rotation state of the first dial 341A. The second adjuster 55 changes the amount of change in the BPM of the second song for each unit rotation angle of the second dial 341B according to the rotation state of the second dial 341B.
　このような構成によれば、第１ダイヤル３４１Ａの回転状態を変更することによって、第１ダイヤル３４１Ａの単位回転角度毎の楽曲の再生速度の変化量を変化させることができる。すなわち、第１ダイヤル３４１Ａの回転操作の仕方を変更することによって、当該変化量を変化させることができる。このため、第１ダイヤル３４１Ａの回転角度が同じであっても、第１楽曲の再生速度を大きく変化させる場合と、第１楽曲の再生速度を小さく変化させる場合とを切り替えることができる。従って、ＳＨＩＦＴボタン等を押すことなく、第１楽曲の再生速度を容易に調節でき、音響制御装置１の利便性を高めることができる。第２ダイヤル３４１Ｂ及び第２調節部５５についても同様である。 According to such a configuration, by changing the rotation state of the first dial 341A, it is possible to change the amount of change in the music playback speed for each unit rotation angle of the first dial 341A. That is, the amount of change can be changed by changing the manner in which the first dial 341A is rotated. Therefore, even if the rotation angle of the first dial 341A is the same, it is possible to switch between a case where the reproduction speed of the first music is greatly changed and a case where the reproduction speed of the first music is slightly changed. Therefore, the playback speed of the first music can be easily adjusted without pressing the SHIFT button or the like, and the convenience of the sound control device 1 can be enhanced. The same is true for the second dial 341B and the second adjusting section 55 as well.
　音響制御装置１では、第１ダイヤル３４１Ａの回転状態は、第１ダイヤル３４１Ａの回転速度を含む。同様に、第２ダイヤル３４１Ｂの回転状態は、第２ダイヤル３４１Ｂの回転速度を含む。このため、制御部５の第１調節部５２は、第１ダイヤル３４１Ａの回転速度に応じて、第１ダイヤル３４１Ａの単位回転角度毎の楽曲の再生速度の変化量を変化させる。制御部５の第２調節部５５は、第２ダイヤル３４１Ｂの回転速度に応じて、第２ダイヤル３４１Ｂの単位回転角度毎の楽曲の再生速度の変化量を変化させる。
　このような構成によれば、第１ダイヤル３４１Ａを回転させるときに、第１ダイヤル３４１Ａの回転速度を変化させることによって、第１ダイヤル３４１Ａの回転角度が同じであっても、第１楽曲の再生速度を大きく変化させる場合と、第１楽曲の再生速度を微調整する場合とを切り替えることができる。従って、片手で第１楽曲の再生速度を容易に調節でき、音響制御装置１の利便性を高めることができる。第２ダイヤル３４１Ｂ及び第２調節部５５についても同様である。 In the acoustic control device 1, the rotational state of the first dial 341A includes the rotational speed of the first dial 341A. Similarly, the rotational state of the second dial 341B includes the rotational speed of the second dial 341B. Therefore, the first adjustment unit 52 of the control unit 5 changes the amount of change in the music reproduction speed for each unit rotation angle of the first dial 341A according to the rotation speed of the first dial 341A. The second adjustment unit 55 of the control unit 5 changes the amount of change in the music reproduction speed for each unit rotation angle of the second dial 341B according to the rotation speed of the second dial 341B.
According to such a configuration, by changing the rotation speed of the first dial 341A when rotating the first dial 341A, even if the rotation angle of the first dial 341A is the same, the first musical piece can be reproduced. It is possible to switch between a case where the speed is greatly changed and a case where the reproduction speed of the first music is finely adjusted. Therefore, the reproduction speed of the first music can be easily adjusted with one hand, and the convenience of the sound control device 1 can be enhanced. The same is true for the second dial 341B and the second adjusting section 55 as well.
　音響制御装置１では、制御部５の第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度未満である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を、第１変化量とする。また、制御部５の第１調節部５２は、第１ダイヤル３４１Ａの回転速度が所定速度以上である間、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を、第１変化量よりも大きい第２変化量とする。制御部５の第２調節部５５も同様である。
　このような構成によれば、第１ダイヤル３４１Ａの回転速度に応じて、第１ダイヤル３４１Ａの単位回転角度毎の第１楽曲のＢＰＭの変化量を第１変化量と第２変化量とで切り替えることができる。このため、第１楽曲のＢＰＭ及び再生速度を大きく変更する場合の第１ダイヤル３４１Ａの操作と、小さく変更する場合の第１ダイヤル３４１Ａの操作とを容易に切り替えることができる他、調節後の楽曲のＢＰＭ及び再生速度をユーザーが把握しやすくすることができる。従って、第１楽曲の再生速度を容易に調節でき、音響制御装置１の利便性を高めることができる。第２調節部５５によっても同様の効果を奏することができる。 In the sound control device 1, the first adjustment unit 52 of the control unit 5 adjusts the amount of change in the BPM of the first song for each unit rotation angle of the first dial 341A while the rotation speed of the first dial 341A is less than the predetermined speed. is the first amount of change. Further, the first adjustment unit 52 of the control unit 5 adjusts the amount of change in the BPM of the first song for each unit rotation angle of the first dial 341A while the rotation speed of the first dial 341A is equal to or higher than the predetermined speed. A second amount of change larger than the amount of change is used. The same applies to the second adjusting section 55 of the control section 5 .
According to such a configuration, the change amount of the BPM of the first music piece for each unit rotation angle of the first dial 341A is switched between the first change amount and the second change amount according to the rotational speed of the first dial 341A. be able to. Therefore, it is possible to easily switch between the operation of the first dial 341A for greatly changing the BPM and playback speed of the first song and the operation of the first dial 341A for slightly changing the BPM and playback speed of the first song. It is possible to make it easier for the user to grasp the BPM and playback speed of the music. Therefore, the playback speed of the first music can be easily adjusted, and the convenience of the sound control device 1 can be enhanced. A similar effect can be obtained by the second adjusting section 55 as well.
　音響制御装置１では、第１ダイヤル３４１Ａの回転加速度を検出する第１検出部３４２Ａと、第２ダイヤル３４１Ｂの回転加速度を検出する第２検出部３４２Ｂと、を備える。制御部５の第１調節部５２は、第１検出部３４２Ａによって検出される第１ダイヤル３４１Ａの回転加速度に基づいて第１ダイヤル３４１Ａの回転速度を算出する。制御部５の第２調節部５５は、第２検出部３４２Ｂによって検出される第２ダイヤル３４１Ｂの回転加速度に基づいて第２ダイヤル３４１Ｂの回転速度を算出する。
　このような構成によれば、第１ダイヤル３４１Ａの回転角度及び回転時間に基づいて回転速度を算出する場合に比べて、第１ダイヤル３４１Ａの回転速度が上記所定速度未満であるか否か、上記所定速度以上であるか否かを迅速に判定できる。このため、第１ダイヤル３４１Ａの単位回転角度毎の楽曲の再生速度の変化量を迅速に決定できるので、第１ダイヤル３４１Ａの回転操作に応じた第１楽曲の再生速度に調節しやすくすることができる。従って、第１ダイヤル３４１Ａの回転角度と第１楽曲の再生速度の調節量とをリンクさせやすくすることができ、第１ダイヤル３４１Ａの操作感及び音響制御装置１の利便性を一層高めることができる。第２検出部３４２Ｂ及び第２調節部５５によっても同様の効果を奏することができる。 The acoustic control device 1 includes a first detection section 342A that detects rotational acceleration of the first dial 341A and a second detection section 342B that detects rotational acceleration of the second dial 341B. The first adjuster 52 of the controller 5 calculates the rotational speed of the first dial 341A based on the rotational acceleration of the first dial 341A detected by the first detector 342A. The second adjuster 55 of the controller 5 calculates the rotational speed of the second dial 341B based on the rotational acceleration of the second dial 341B detected by the second detector 342B.
According to such a configuration, compared to the case where the rotation speed is calculated based on the rotation angle and the rotation time of the first dial 341A, whether or not the rotation speed of the first dial 341A is less than the predetermined speed can be determined as described above. It is possible to quickly determine whether or not the speed is equal to or higher than the predetermined speed. Therefore, the change amount of the music reproduction speed for each unit rotation angle of the first dial 341A can be quickly determined, so that it is possible to easily adjust the reproduction speed of the first music according to the rotation operation of the first dial 341A. can. Therefore, it is possible to easily link the rotation angle of the first dial 341A and the adjustment amount of the playback speed of the first music piece, and the operational feeling of the first dial 341A and the convenience of the sound control device 1 can be further enhanced. . The same effect can be obtained by the second detection section 342B and the second adjustment section 55 as well.
　音響制御装置１では、制御部５の第１調節部５２は、第１ダイヤル３４１Ａが時計回りに回転されると、第１楽曲のＢＰＭを増加させ、ひいては、第１楽曲の再生速度を増加させる。制御部５の第１調節部５２は、第１ダイヤル３４１Ａが反時計回りに回転されると、第１楽曲のＢＰＭを減少させ、ひいては、第１楽曲の再生速度を減少させる。時計回りは、第１回転方向に相当し、反時計回りは、第１回転方向とは反対方向に相当する。制御部５の第２調節部５５Ｂも同様である。
　このような構成によれば、第１ダイヤル３４１Ａの回転方向に応じて、第１楽曲の再生速度を増加又は減少させることができる。従って、第１楽曲の再生速度を調節しやすくすることができ、音響制御装置１の利便性を高めることができる。第２調節部５５によっても同様の効果を奏することができる。 In the sound control device 1, when the first dial 341A is rotated clockwise, the first adjustment section 52 of the control section 5 increases the BPM of the first music piece, thereby increasing the playback speed of the first music piece. . When the first dial 341A is rotated counterclockwise, the first adjustment section 52 of the control section 5 reduces the BPM of the first music, thereby reducing the playback speed of the first music. Clockwise rotation corresponds to the first rotation direction, and counterclockwise rotation corresponds to the direction opposite to the first rotation direction. The same applies to the second adjustment section 55B of the control section 5 .
According to such a configuration, the playback speed of the first music can be increased or decreased according to the rotation direction of the first dial 341A. Therefore, the reproduction speed of the first music can be easily adjusted, and the convenience of the sound control device 1 can be enhanced. A similar effect can be obtained by the second adjusting section 55 as well.
　音響制御装置１では、天面２１に第１ダイヤル３４１Ａが回転可能に設けられる筐体２を備える。上記のように、第１回転方向は、天面２１に対向する位置から見て時計回りの方向である。なお、天面２１は、第１面に相当する。
　一般的に、所定の指標の数値を増加させるときのダイヤルの操作方向は時計回りであり、当該数値を減少させるときのダイヤルの操作方向は反時計回りである。
　これに対し、第１ダイヤル３４１Ａを時計回りに回転させることによって、第１楽曲の再生速度を増加させることができ、第１ダイヤル３４１Ａを反時計回りに回転させることによって、第１楽曲の再生速度を減少させることができる。従って、第１楽曲の再生速度を増加又は減少させるときの第１ダイヤルの操作方向をユーザーが把握しやすくすることができるので、第１楽曲の再生速度の調節操作を容易に実施しやすくすることができる。天面２１に回転可能に設けられる第２ダイヤル３４１Ｂについても同様である。 The acoustic control device 1 includes the housing 2 in which the first dial 341A is rotatably provided on the top surface 21 . As described above, the first rotation direction is the clockwise direction when viewed from the position facing the top surface 21 . Note that the top surface 21 corresponds to the first surface.
In general, the dial is operated clockwise to increase the numerical value of a predetermined index, and the dial is operated counterclockwise to decrease the numerical value.
On the other hand, by rotating the first dial 341A clockwise, the playback speed of the first song can be increased, and by rotating the first dial 341A counterclockwise, the playback speed of the first song can be increased. can be reduced. Therefore, it is possible for the user to easily grasp the operation direction of the first dial when increasing or decreasing the reproduction speed of the first music piece, so that the adjustment operation of the reproduction speed of the first music piece can be easily performed. can be done. The same applies to the second dial 341B rotatably provided on the top surface 21. As shown in FIG.
　音響制御装置１は、第１通知部３４３Ａ及び第２通知部３４３Ｂを備える。第１通知部３４３Ａは、第１楽曲に固有のＢＰＭに対する再生速度調節後の第１楽曲のＢＰＭの割合が第１限界値及び第２限界値のうちの一方の限界値に到達すると、当該割合が当該一方の限界値に到達したことを通知する。第２通知部３４３Ｂも同様である。すなわち、第１通知部３４３Ａ及び第２通知部３４３Ｂは、通知部に相当し、第１限界値及び第２限界値は、所定値に相当する。
　このような構成によれば、ユーザーがダイヤルを回転させている場合でも、ユーザーは、上記割合が第１限界値又は第２限界値に到達したことを把握できる。従って、音響制御装置１の利便性を高めることができる。 The sound control device 1 includes a first notification section 343A and a second notification section 343B. When the ratio of the BPM of the first music piece after the playback speed adjustment to the BPM specific to the first music piece reaches one of the first limit value and the second limit value, the first notification unit 343A reaches one of the limit values. The same applies to the second notification section 343B. That is, the first notification section 343A and the second notification section 343B correspond to the notification section, and the first limit value and the second limit value correspond to the predetermined values.
According to such a configuration, even when the user rotates the dial, the user can grasp that the ratio has reached the first limit value or the second limit value. Therefore, the convenience of the acoustic control device 1 can be enhanced.
　音響制御装置１では、第１通知部３４３Ａは、第１ダイヤル３４１Ａが回転されて、第１楽曲に固有のＢＰＭに対する再生速度調節後の第１楽曲のＢＰＭの割合が所定値に到達すると、第１ダイヤル３４１Ａが回転されていた方向への第１ダイヤル３４１Ａの回転を規制する。すなわち、第１通知部３４３Ａは、時計回り及び反時計回りのうち一方の方向に第１ダイヤル３４１Ａが回転されて、第１楽曲に固有のＢＰＭに対する再生速度調節後の楽曲のＢＰＭの割合が所定値に到達すると、当該一方の方向への第１ダイヤル３４１Ａの回転を規制する。これにより、第１通知部３４３Ａは、第１調節後割合が第１限界値又は第２限界値に到達したことを通知する。第２通知部３４３Ｂも同様である。
　このような構成によれば、上記割合が第１限界値又は第２限界値に到達したことをユーザーが把握しやすくすることができる。従って、音響制御装置１の利便性を一層高めることができる。 In the sound control device 1, when the first dial 341A is rotated and the ratio of the BPM of the first musical piece after adjusting the playback speed to the BPM specific to the first musical piece reaches a predetermined value, the first notification unit 343A Rotation of the first dial 341A in the direction in which the 1 dial 341A was rotated is restricted. That is, the first notification unit 343A rotates the first dial 341A in one of the clockwise and counterclockwise directions, and the ratio of the BPM of the song after the playback speed adjustment to the BPM specific to the first song is set to a predetermined ratio. When the value is reached, rotation of the first dial 341A in the one direction is restricted. Thereby, the first notification unit 343A notifies that the first post-adjustment ratio has reached the first limit value or the second limit value. The same applies to the second notification section 343B.
According to such a configuration, it is possible for the user to easily grasp that the ratio has reached the first limit value or the second limit value. Therefore, the convenience of the acoustic control device 1 can be further enhanced.
　音響制御装置１は、第１表示部３４４Ａ及び第２表示部３４４Ｂを備える。第１表示部３４４Ａは、制御部５によって調節された第１楽曲の再生速度に関する情報を表示する。第２表示部３４４Ｂは、制御部５によって調節された第２楽曲の再生速度に関する情報を表示する。
　このような構成によれば、第１表示部３４４Ａ及び第２表示部３４４Ｂによる表示内容を確認することによって、第１楽曲及び第２楽曲の再生速度を調節しやすくすることができる。 The acoustic control device 1 includes a first display section 344A and a second display section 344B. 344 A of 1st display parts display the information regarding the reproduction speed of the 1st music adjusted by the control part 5. FIG. The second display section 344B displays information about the playback speed of the second music adjusted by the control section 5. FIG.
According to such a configuration, it is possible to easily adjust the playback speed of the first music piece and the second music piece by confirming the display contents of the first display section 344A and the second display section 344B.
　音響制御装置１では、第１表示部３４４Ａは、制御部５の第１調節部５２によって調節された第１楽曲の再生速度に関する情報として、第１楽曲に固有のＢＰＭに対する再生速度調節後の第１楽曲のＢＰＭの割合を示す情報を表示する。すなわち、第１表示部３４４Ａは、再生速度調節後の第１楽曲の再生速度に関する情報として、第１オリジナルＢＰＭに対する第１調節後ＢＰＭの割合である第１調節後割合を示す情報を表示する。第２表示部３４４Ｂも同様である。
　このような構成によれば、現在の第１調節後ＢＰＭが第１オリジナルＢＰＭに対してどの程度調節されたのかを、ユーザーが直感的に把握できる。従って、第１楽曲の再生速度を調節しやすくすることができる。第２表示部３４４Ｂによっても同様の効果を奏することができる。 In the sound control device 1, the first display unit 344A displays, as information about the reproduction speed of the first music piece adjusted by the first adjustment unit 52 of the control unit 5, the BPM specific to the first music piece after adjusting the reproduction speed. Information indicating the BPM ratio of one piece of music is displayed. That is, the first display unit 344A displays information indicating the first post-adjustment ratio, which is the ratio of the first post-adjustment BPM to the first original BPM, as information on the playback speed of the first music piece after the playback speed adjustment. The same applies to the second display section 344B.
According to such a configuration, the user can intuitively grasp how much the current first adjusted BPM has been adjusted with respect to the first original BPM. Therefore, it is possible to easily adjust the playback speed of the first music piece. A similar effect can be obtained by the second display section 344B.
　［第１実施形態の変形］
　上記説明した音響制御装置１では、表示モードが図形表示モードであるときに、第１調節後割合に応じて、図形ＦＧ１，ＦＧ２の輝度を変更するとした。しかしながら、これに限らず、第１調節後割合に応じて、図形ＦＧ１，ＦＧ２の輝度、色及び点滅周期の少なくとも１つを変更する構成としてもよい。 [Modification of the first embodiment]
In the acoustic control device 1 described above, when the display mode is the graphic display mode, the brightness of the graphics FG1 and FG2 is changed according to the first post-adjustment ratio. However, the present invention is not limited to this, and at least one of the brightness, color, and flashing cycle of the graphics FG1 and FG2 may be changed according to the first post-adjustment ratio.
　図９は、表示モードが図形表示モードであるときに、第１調節後割合と、表示される図形ＦＧ１，ＦＧ２との関係を説明する図である。
　例えば、表示モードが図形表示モードであるときに、図形ＦＧ１，ＦＧ２を図９に示すように表示させてもよい。
　すなわち、第１調節後割合が１００％より大きく、第１閾値（例えば１１０％）未満である場合には、表示制御部５８は、図形ＦＧ１の色を赤色とする。第１調節後割合が第１閾値以上、第２閾値（例えば１２０％）未満である場合には、表示制御部５８は、図形ＦＧ１の色を橙色とする。第１調節後割合が第２閾値以上である場合には、表示制御部５８は、図形ＦＧ１の色を黄色とする。 FIG. 9 is a diagram illustrating the relationship between the first post-adjustment ratio and the graphics FG1 and FG2 displayed when the display mode is the graphics display mode.
For example, when the display mode is the figure display mode, figures FG1 and FG2 may be displayed as shown in FIG.
That is, when the first post-adjustment ratio is greater than 100% and less than the first threshold value (for example, 110%), the display control unit 58 sets the color of the graphic FG1 to red. When the first post-adjustment ratio is greater than or equal to the first threshold and less than the second threshold (for example, 120%), the display control unit 58 sets the color of the graphic FG1 to orange. When the first post-adjustment ratio is equal to or greater than the second threshold, the display control unit 58 sets the color of the graphic FG1 to yellow.
　また、第１調節後割合が第３閾値（例えば９０％）よりも大きく、１００％未満である場合には、表示制御部５８は、図形ＦＧ２の色を青緑色とする。第１調節後割合が第３閾値以下であり、第４閾値（例えば８０％）よりも大きい場合には、表示制御部５８は、図形ＦＧ２の色を青色とする。第１調節後割合が第４閾値以下である場合には、表示制御部５８は、図形ＦＧ２の色を青紫色とする。
　なお、第１調節後ＢＰＭが第１オリジナルＢＰＭと同じ値である場合には、上記と同様に、図形ＦＧ１，ＦＧ２は表示されない。 Further, when the first post-adjustment ratio is greater than the third threshold value (for example, 90%) and less than 100%, the display control unit 58 sets the color of the graphic FG2 to bluish green. When the first post-adjustment ratio is equal to or less than the third threshold and greater than the fourth threshold (80%, for example), the display control unit 58 sets the color of the graphic FG2 to blue. When the first post-adjustment ratio is equal to or less than the fourth threshold, the display control unit 58 sets the color of the graphic FG2 to bluish purple.
Note that when the first adjusted BPM is the same as the first original BPM, the graphics FG1 and FG2 are not displayed in the same manner as described above.
　このように、音響制御装置１において、図形ＦＧ１，ＦＧ２の色は、調節後割合に応じて異なってもよい。
　このような構成によれば、図形ＦＧ１，ＦＧ２の色を確認することによって、調節後割合を容易に把握できる。
　また、調節後割合が１００％を超える場合には、図形ＦＧ１の色を暖色とし、調節後割合が１００％未満である場合には、図形ＦＧ２の色を寒色とすることによって、ユーザーは、オリジナルＢＰＭと調節後ＢＰＭとの大小関係をより直感的に把握できる。
　なお、調節後割合と図形ＦＧ１，ＦＧ２の色との関係は、上記に限定されず、図形ＦＧ１，ＦＧ２の色は、他の色であってもよい。 Thus, in the sound control device 1, the colors of the graphics FG1 and FG2 may differ according to the post-adjustment ratio.
According to such a configuration, the post-adjustment ratio can be easily grasped by confirming the colors of the figures FG1 and FG2.
Further, when the post-adjustment ratio exceeds 100%, the color of the graphic FG1 is set to a warm color, and when the post-adjustment ratio is less than 100%, the color of the graphic FG2 is set to a cool color. The magnitude relationship between the BPM and the adjusted BPM can be grasped more intuitively.
Note that the relationship between the ratio after adjustment and the colors of the graphics FG1 and FG2 is not limited to the above, and the colors of the graphics FG1 and FG2 may be other colors.
　図１０は、表示モードが図形表示モードであるときに、調節後割合と、表示される図形ＦＧ１，ＦＧ２との関係を説明する図である。
　例えば、表示モードが図形表示モードであるときに、図形ＦＧ１，ＦＧ２を図１０に示すように表示させてもよい。
　すなわち、調節後割合が１００％より大きく、第１閾値（例えば１１０％）未満である場合には、表示制御部５８は、図形ＦＧ１の点滅周期を大きい値とする。調節後割合が第１閾値以上、第２閾値（例えば１２０％）未満である場合には、表示制御部５８は、図形ＦＧ１の点滅周期を、調節後割合が１００％より大きく、第１閾値未満である場合の点滅周期よりも小さい値とする。調節後割合が第２閾値以上である場合には、表示制御部５８は、図形ＦＧ１の点滅周期を最も小さい値とする。なお、点滅周期が大きいとは、点滅周波数が低く、点滅頻度が低いことを示し、点滅周期が小さいとは、点滅周波数が高く、点滅頻度が高いことを示す。 FIG. 10 is a diagram for explaining the relationship between the post-adjustment ratio and the graphics FG1 and FG2 displayed when the display mode is the graphics display mode.
For example, when the display mode is the graphic display mode, the graphics FG1 and FG2 may be displayed as shown in FIG.
That is, when the post-adjustment ratio is greater than 100% and less than the first threshold value (for example, 110%), the display control unit 58 sets the flickering cycle of the graphic FG1 to a large value. When the post-adjustment ratio is greater than or equal to the first threshold and less than a second threshold (for example, 120%), the display control unit 58 sets the blinking period of the graphic FG1 to a value where the post-adjustment ratio is greater than 100% and less than the first threshold. A value smaller than the flashing period when . When the post-adjustment ratio is equal to or greater than the second threshold, the display control unit 58 sets the blinking period of the graphic FG1 to the smallest value. A long flashing cycle indicates a low flashing frequency and a low flashing frequency, and a short flashing cycle indicates a high flashing frequency and a high flashing frequency.
　また、調節後割合が第３閾値（例えば９０％）よりも大きく、１００％未満である場合には、表示制御部５８は、図形ＦＧ２の点滅周期を大きい値とする。調節後割合が第３閾値以下であり、第４閾値（例えば８０％）よりも大きい場合には、表示制御部５８は、図形ＦＧ２の点滅周期を、調節後割合が第３閾値よりも大きく、１００％未満である場合の点滅周期よりも小さい値とする。調節後割合が第４閾値以下である場合には、表示制御部５８は、図形ＦＧ２の点滅周期を最も小さい値とする。
　このように、オリジナルＢＰＭと調節後ＢＰＭとの差分が大きくなるに従って、図形ＦＧ１，ＦＧ２の点滅周期は小さくなり、図形ＦＧ１，ＦＧ２の点滅頻度は高くなる。換言すると、オリジナルＢＰＭと調節後ＢＰＭとの差分が小さくなるに従って、図形ＦＧ１，ＦＧ２の点滅周期は大きくなり、図形ＦＧ１，ＦＧ２の点滅頻度は低くなる。
　なお、調節後ＢＰＭがオリジナルＢＰＭと同じ値である場合には、上記と同様に、図形ＦＧ１，ＦＧ２は表示されない。 Further, when the post-adjustment ratio is greater than the third threshold value (for example, 90%) and less than 100%, the display control unit 58 sets the flickering cycle of the graphic FG2 to a large value. If the post-adjustment ratio is equal to or less than the third threshold and is larger than the fourth threshold (for example, 80%), the display control unit 58 sets the flickering cycle of the graphic FG2 so that the post-adjustment ratio is larger than the third threshold. A value smaller than the flashing period when the rate is less than 100%. When the post-adjustment ratio is equal to or less than the fourth threshold, the display control unit 58 sets the blinking period of the graphic FG2 to the smallest value.
In this manner, as the difference between the original BPM and the adjusted BPM increases, the blinking period of the graphics FG1 and FG2 decreases and the blinking frequency of the graphics FG1 and FG2 increases. In other words, as the difference between the original BPM and the adjusted BPM becomes smaller, the blinking period of the graphics FG1 and FG2 increases and the blinking frequency of the graphics FG1 and FG2 decreases.
Note that when the adjusted BPM is the same value as the original BPM, the graphics FG1 and FG2 are not displayed in the same manner as described above.
　このように、音響制御装置１において、図形ＦＧ１，ＦＧ２の点滅周期は、調節後割合に応じて異なってもよい。
　このような構成によれば、図形ＦＧ１，ＦＧ２の点滅周期を確認することによって、調節後割合を容易に把握できる。
　また、オリジナルＢＰＭと調節後ＢＰＭとの差分が小さくなり、調節後割合が１００％に近くなるに従って、図形ＦＧ１，ＦＧ２の点滅周期を大きくすることによって、ユーザーは、調節後割合を把握しやすくすることができる。換言すると、オリジナルＢＰＭと調節後ＢＰＭとの差分が大きくなり、調節後割合が１００％から離れるに従って、図形ＦＧ１，ＦＧ２の点滅周期を小さくすることによって、ユーザーは、調節後割合を把握しやすくすることができる。 Thus, in the sound control device 1, the flickering periods of the graphics FG1 and FG2 may differ according to the post-adjustment ratio.
According to such a configuration, the post-adjustment ratio can be easily grasped by confirming the flickering period of the figures FG1 and FG2.
Also, as the difference between the original BPM and the BPM after adjustment becomes smaller and the ratio after adjustment approaches 100%, the flickering period of the graphics FG1 and FG2 is increased to make it easier for the user to grasp the ratio after adjustment. be able to. In other words, as the difference between the original BPM and the BPM after adjustment increases and the ratio after adjustment deviates from 100%, the flickering period of the graphics FG1 and FG2 is decreased, thereby making it easier for the user to grasp the ratio after adjustment. be able to.
　なお、調節後割合と図形ＦＧ１，ＦＧ２の点滅周期との関係は、上記に限定されず、例えば調節後割合が１００％に近くなるに従って、図形ＦＧ１，ＦＧ２の点滅周期を小さくしてもよい。換言すると、オリジナルＢＰＭと調節後ＢＰＭとの差分が小さくなるに従って、図形ＦＧ１，ＦＧ２の点滅周期を小さくして、図形ＦＧ１，ＦＧ２の点滅頻度を高くしてもよい。また、オリジナルＢＰＭと調節後ＢＰＭとの差分が大きくなるに従って、図形ＦＧ１，ＦＧ２の点滅周期を大きくして、図形ＦＧ１，ＦＧ２の点滅頻度を低くしてもよい。なお、オリジナルＢＰＭと調節後ＢＰＭとが一致する場合には、図形ＦＧ１，ＦＧ２は、点灯されずに消灯される。
　このような構成によれば、点滅頻度が高い状態にて点滅していた図形ＦＧ１，ＦＧ２の消灯を確認することによって、ユーザーは、オリジナルＢＰＭと調節後ＢＰＭとが一致していることを容易に把握できる。 Note that the relationship between the post-adjustment ratio and the flickering cycles of the figures FG1 and FG2 is not limited to the above. In other words, as the difference between the original BPM and the BPM after adjustment becomes smaller, the flickering cycle of the graphics FG1 and FG2 may be reduced to increase the flickering frequency of the graphics FG1 and FG2. Further, as the difference between the original BPM and the adjusted BPM increases, the blinking period of the graphics FG1 and FG2 may be increased, and the blinking frequency of the graphics FG1 and FG2 may be decreased. Note that when the original BPM and the adjusted BPM match, the figures FG1 and FG2 are turned off without being lit.
According to such a configuration, the user can easily confirm that the original BPM and the adjusted BPM match by confirming that the graphics FG1 and FG2, which were blinking in a state of high blinking frequency, are turned off. I can grasp it.

　［音響制御装置の概略構成］
　図１１は、本実施形態に係る音響制御装置が備えるダイヤル３４６を示す模式図である。
　本実施形態に係る音響制御装置は、第１実施形態に係るダイヤル３４１に代えて、図１１に示すダイヤル３４６及び割合表示部３４７を備える他は、第１実施形態に係る音響制御装置１と同様の構成及び機能を備える。すなわち、本実施形態では、再生速度操作部３４は、ダイヤル３４６、検出部３４２、通知部３４３、表示部３４４、切替操作部３４５及び割合表示部３４７を有する。 [Schematic configuration of acoustic control device]
FIG. 11 is a schematic diagram showing the dial 346 included in the acoustic control device according to this embodiment.
The sound control device according to the present embodiment is the same as the sound control device 1 according to the first embodiment, except that the dial 341 according to the first embodiment is replaced with a dial 346 and a ratio display section 347 shown in FIG. It has the configuration and function of That is, in this embodiment, the playback speed operation section 34 has a dial 346 , a detection section 342 , a notification section 343 , a display section 344 , a switching operation section 345 and a ratio display section 347 .
　［ダイヤルの構成］
　ダイヤル３４６は、ダイヤル３４１と同様に、天面２１に対向する位置から見て時計回り及び反時計回りに回転可能に設けられ、楽曲の再生速度を調節する操作を受け付ける。ダイヤル３４６には、割合表示部３４７が設けられている。 [Dial configuration]
Like the dial 341, the dial 346 is rotatable clockwise and counterclockwise when viewed from the position facing the top surface 21, and accepts an operation for adjusting the playback speed of music. A ratio display portion 347 is provided on the dial 346 .
　［割合表示部の構成］

　割合表示部３４７は、ダイヤル３４６の周方向に設けられた基点ＢＰから時計回りに半周分の領域である第１領域３４７Ａと、基点ＢＰから反時計回りに半周分の領域である第２領域３４７Ｂとを有する。
　第１領域３４７Ａは、調節後ＢＰＭがオリジナルＢＰＭよりも大きい場合に調節後割合を表示する領域である。詳述すると、第１領域３４７Ａは、調節後割合が１００％よりも大きく、２００％未満である場合に、調節後割合を表示する領域である。

　なお、基点ＢＰは、ダイヤル３４６の回転軸Ｒｘから上方向に延びる仮想線ＶＬと、ダイヤル３４６の回転軸Ｒｘを中心とする周方向との交差部に設定されている。上記のように、ダイヤル３４６は、回転軸Ｒｘを中心として回転可能であることから、基点ＢＰの位置は、ダイヤル３４６が回転されたときには表示制御部５８によって常に更新される。 [Structure of ratio display part]
The ratio display section 347 displays the adjusted ratio under the control of the display control section 58 . The ratio display section 347 is composed of a plurality of light emitting elements 348 arranged along the rotation direction of the dial 346 .
The ratio display portion 347 includes a first region 347A that is half a clockwise region from the base point BP provided in the circumferential direction of the dial 346, and a second region 347B that is a half counterclockwise region from the base point BP. and
The first area 347A is an area for displaying the post-adjustment ratio when the post-adjustment BPM is greater than the original BPM. Specifically, the first area 347A is an area that displays the post-adjustment percentage when the post-adjustment percentage is greater than 100% and less than 200%.
The second area 347B is an area for displaying the post-adjustment ratio when the post-adjustment BPM is smaller than the original BPM. More specifically, the second area 347B is an area that displays the post-adjustment percentage when the post-adjustment percentage is greater than 0% and less than 100%.
The base point BP is set at the intersection of the virtual line VL extending upward from the rotation axis Rx of the dial 346 and the circumferential direction about the rotation axis Rx of the dial 346 . As described above, since the dial 346 is rotatable around the rotation axis Rx, the position of the base point BP is constantly updated by the display control section 58 when the dial 346 is rotated.
　［割合表示部の機能］
　図１２は、割合表示部３４７の表示態様の一例を示す図である。具体的に、図１２は、調節後割合が１３０％であるときの割合表示部３４７を示す図である。
　表示制御部５８は、割合表示部３４７が有する複数の発光素子３４８のうち、調節後割合に応じた数の発光素子３４８を点灯させることによって調節後割合を割合表示部３４７に表示させる。詳述すると、表示制御部５８は、調節後ＢＰＭがオリジナルＢＰＭよりも大きい場合には、第１領域３４７Ａに配置された複数の発光素子３４８のうち、１００％と調節後割合との差分に応じた数の発光素子３４８を基点ＢＰから点灯させることによって、調節後割合を表示させる。
　例えば、調節後割合が１３０％である場合、表示制御部５８は、図１２に示すように、第１領域３４７Ａに配置された複数の発光素子３４８のうち、１００％と調節後割合との差分である３０％に応じた数の発光素子３４８を基点ＢＰから点灯させることによって、調節後割合を割合表示部３４７に表示させる。 [Function of ratio display part]
FIG. 12 is a diagram showing an example of the display mode of the ratio display section 347. As shown in FIG. Specifically, FIG. 12 is a diagram showing the ratio display portion 347 when the post-adjustment ratio is 130%.
The display control unit 58 causes the ratio display unit 347 to display the post-adjustment ratio by turning on the number of light emitting elements 348 corresponding to the post-adjustment ratio among the plurality of light emitting elements 348 of the ratio display unit 347 . More specifically, when the adjusted BPM is greater than the original BPM, the display control unit 58 controls the difference between 100% of the plurality of light emitting elements 348 arranged in the first region 347A and the adjusted ratio. The post-adjustment ratio is displayed by lighting the same number of light-emitting elements 348 from the base point BP.
For example, when the post-adjustment ratio is 130%, the display control unit 58, as shown in FIG. The post-adjustment ratio is displayed on the ratio display section 347 by lighting the number of light emitting elements 348 corresponding to 30% from the base point BP.
　図１３は、割合表示部３４７の表示態様の一例を示す図である。具体的に、図１３は、調節後割合が８０％であるときの割合表示部３４７を示す図である。
　また、表示制御部５８は、調節後ＢＰＭがオリジナルＢＰＭよりも小さい場合には、第２領域３４７Ｂに配置された複数の発光素子３４８のうち、１００％と調節後割合との差分に応じた数の発光素子３４８を基点ＢＰから点灯させることによって、調節後割合を表示させる。
　例えば、調節後割合が８０％である場合、表示制御部５８は、図１３に示すように、第２領域３４７Ｂに配置された複数の発光素子３４８のうち、１００％と調節後割合との差分である２０％に応じた数の発光素子３４８を基点ＢＰから点灯させることによって、調節後割合を割合表示部３４７に表示させる。 FIG. 13 is a diagram showing an example of the display mode of the ratio display section 347. As shown in FIG. Specifically, FIG. 13 is a diagram showing the ratio display portion 347 when the post-adjustment ratio is 80%.
Further, when the BPM after adjustment is smaller than the original BPM, the display control unit 58 controls the number of light-emitting elements 348 arranged in the second region 347B according to the difference between 100% and the ratio after adjustment. The post-adjustment ratio is displayed by lighting the light-emitting element 348 from the base point BP.
For example, when the post-adjustment ratio is 80%, the display control unit 58, as shown in FIG. The post-adjustment ratio is displayed on the ratio display section 347 by lighting the number of light emitting elements 348 corresponding to 20% from the base point BP.
　このように、基点ＢＰを中心として、時計回りの第１領域３４７Ａ及び反時計回りの第２領域３４７Ｂのうちの一方が調節後割合を表示することによって、ユーザーは、調節後割合を直感的に把握できる。
　なお、第１領域３４７Ａに配置された発光素子３４８の発光色と、第２領域３４７Ｂに配置された発光素子３４８の発光色とは、異なっていてもよい。例えば、調節後ＢＰＭがオリジナルＢＰＭよりも大きい場合に点灯される発光素子３４８は、暖色のうち赤色で点灯し、調節後ＢＰＭがオリジナルＢＰＭよりも小さい場合に点灯される発光素子３４８は、寒色のうち青色で点灯してもよい。更に、発光素子３４８は、上記第１実施形態の変形と同様に、調節後割合に応じた周波数で点滅してもよい。
　以上説明した本実施形態に係る音響制御装置は、第１実施形態に係る音響制御装置１と同様の効果を奏する。 In this way, one of the clockwise first region 347A and the counterclockwise second region 347B displays the post-adjustment ratio centering on the base point BP, so that the user can intuitively see the post-adjustment ratio. I can grasp it.
The luminescent color of the light emitting element 348 arranged in the first region 347A and the luminescent color of the light emitting element 348 arranged in the second region 347B may be different. For example, the light-emitting elements 348 that are lit when the adjusted BPM is greater than the original BPM are lit in red among the warm colors, and the light-emitting elements 348 that are lit when the adjusted BPM is less than the original BPM are lit in cool colors. Of these, blue may be lit. Furthermore, the light emitting element 348 may blink at a frequency corresponding to the post-adjustment ratio, as in the modification of the first embodiment.
The acoustic control device according to the present embodiment described above has the same effects as the acoustic control device 1 according to the first embodiment.
　［第２実施形態の変形］
　図１４は、割合表示部３４７の他の配置を示す図である。
　上記説明した割合表示部３４７は、ダイヤル３４６に設けられているとした。しかしながら、これに限らず、他の場所に設けられていてもよい。
　例えば、図１４に示すように、割合表示部３４７を構成する複数の発光素子３４８は、筐体２の天面２１においてダイヤル３４１の周囲に設けられていてもよい。
　このような構成によれば、複数の発光素子３４８は筐体２に固定されることとなるので、基点ＢＰを固定できる。このため、基点ＢＰから時計回りの第１領域３４７Ａ、及び、基点ＢＰから反時計回りの第２領域３４７Ｂを把握しやすくすることができる。従って、オリジナルＢＰＭと調節後ＢＰＭとの大小関係を容易に把握できる他、点灯される発光素子３４８の配置範囲を確認することによって、調節後割合を把握できる。
　この他、基点ＢＰを固定できることから、回転されるダイヤル３４６における基点ＢＰの位置を算出する処理を省略できる。 [Modification of Second Embodiment]
FIG. 14 is a diagram showing another arrangement of the ratio display section 347. As shown in FIG.
It is assumed that the ratio display portion 347 described above is provided on the dial 346 . However, it is not limited to this, and may be provided in another location.
For example, as shown in FIG. 14 , a plurality of light emitting elements 348 forming a ratio display portion 347 may be provided around the dial 341 on the top surface 21 of the housing 2 .
According to such a configuration, since the plurality of light emitting elements 348 are fixed to the housing 2, the base point BP can be fixed. Therefore, it is possible to easily grasp the first area 347A clockwise from the base point BP and the second area 347B counterclockwise from the base point BP. Therefore, the size relationship between the original BPM and the BPM after adjustment can be easily grasped, and the post-adjustment ratio can be grasped by confirming the arrangement range of the light emitting elements 348 to be lit.
In addition, since the base point BP can be fixed, the process of calculating the position of the base point BP on the rotated dial 346 can be omitted.
　［実施形態の変形］
　本発明は、上記各実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形及び改良等は、本発明に含まれるものである。 [Modification of Embodiment]
The present invention is not limited to the above-described embodiments, and includes modifications, improvements, and the like within the scope of achieving the object of the present invention.
　図１５は、音響制御装置１の変形である音響制御装置１Ａを示す模式図である。
　上記各実施形態では、チャンネル操作部３ごとに再生速度操作部３４が設けられていた。しかしながら、これに限らず、例えば図１５に示す音響制御装置１Ａのように、音響制御装置全体で１つの再生速度操作部３４が設けられていてもよい。この場合、制御部５は、再生速度操作部３４に対する操作に応じて、全てのチャンネルの楽曲の再生速度を同時に調節する。このとき、制御部５は、１つの再生速度操作部３４の回転状態に応じて、全てのチャンネルの楽曲の再生時のＢＰＭを同じ値ずつ増減させてもよく、全てのチャンネルの楽曲の再生時のＢＰＭを同じ割合で増減させてもよい。このような再生速度操作部３４が設けられる場合には、第１チャンネル操作部３Ａは、第１チャンネルの楽曲の再生速度のみ調節可能なテンポスライダー３５を備えていてもよく、第２チャンネル操作部３Ｂは、第２チャンネルの楽曲の再生速度のみ調節可能なテンポスライダー３５を備えていてもよい。 FIG. 15 is a schematic diagram showing an acoustic control device 1A that is a modification of the acoustic control device 1. As shown in FIG.
In each of the above embodiments, the playback speed operation section 34 is provided for each channel operation section 3 . However, the present invention is not limited to this, and one reproduction speed operation unit 34 may be provided for the entire sound control device, such as the sound control device 1A shown in FIG. 15, for example. In this case, the control unit 5 simultaneously adjusts the reproduction speeds of songs on all channels according to the operation on the reproduction speed operation unit 34 . At this time, the control unit 5 may increase or decrease the BPM during reproduction of music on all channels by the same value in accordance with the rotation state of one reproduction speed operation unit 34. may be increased or decreased at the same rate. When such a playback speed operation section 34 is provided, the first channel operation section 3A may be provided with a tempo slider 35 capable of adjusting only the playback speed of the music on the first channel. 3B may have a tempo slider 35 that can adjust only the playback speed of songs on the second channel.
　上記各実施形態では、ダイヤル３４１，３４６の回転状態は、ダイヤル３４１，３４６の回転速度を含むとした。すなわち、制御部５は、ダイヤル３４１，３４６の回転速度に応じて、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量を変化させ、これにより、単位回転角度毎の楽曲の再生速度の変化量を変化させるとした。しかしながら、これに限らず、ダイヤル３４１，３４６の回転状態は、ダイヤル３４１，３４６の回転速度を含まなくてもよく、制御部５は、ダイヤル３４１，３４６の回転状態に応じて、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量を変化させ、単位回転角度毎の楽曲の再生速度の変化量を変化させればよい。例えば、ダイヤル３４１，３４６に対して所定の回転操作が行われた場合に、単位回転角度毎の楽曲のＢＰＭの変化量、及び、単位回転角度毎の楽曲の再生速度の変化量を変化させてもよい。この場合、制御部５は、ダイヤル３４１，３４６が時計回り及び反時計回りのうち一方の方向に所定角度回転され、他方の方向に所定角度回転された後、一方の方向に更に回転されると、後の一方の方向へのダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量を第１変化量から第２変化量に変化させて、単位回転角度毎の楽曲の再生速度の変化量を変化させてもよい。また、この場合、当該変化量を、第２変化量から第１変化量に変化させてもよい。また、制御部５は、ダイヤル３４１，３４６が筐体２に向かって押下されずに回転された場合と、ダイヤル３４１，３４６が筐体２に向かって押下されつつ回転された場合とで、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量、及び、単位回転角度毎の楽曲の再生速度の変化量を変化させてもよい。また、制御部５は、ダイヤル３４１，３４６に対する筐体２に向かう方向への押圧力が所定値未満である場合と、所定値以上である場合とで、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量、及び、単位回転角度毎の楽曲の再生速度の変化量を変化させてもよい。 In each of the above embodiments, the rotational states of the dials 341 and 346 include the rotational speeds of the dials 341 and 346. That is, the control unit 5 changes the amount of change in the BPM of music for each unit rotation angle of the dials 341 and 346 in accordance with the rotation speed of the dials 341 and 346, thereby increasing the reproduction speed of the music for each unit rotation angle. It was assumed that the amount of change in was changed. However, not limited to this, the rotational states of the dials 341 and 346 may not include the rotational speeds of the dials 341 and 346, and the controller 5 controls the dials 341 and 346 according to the rotational states of the dials 341 and 346. By changing the amount of change in the BPM of the music for each unit rotation angle, the amount of change in the reproduction speed of the music for each unit rotation angle may be changed. For example, when a predetermined rotation operation is performed on the dials 341 and 346, the amount of change in the BPM of music for each unit rotation angle and the amount of change in the playback speed of music for each unit rotation angle are changed. good too. In this case, when the dials 341 and 346 are rotated by a predetermined angle in one of clockwise and counterclockwise directions, and then rotated by a predetermined angle in the other direction, the control unit 5 is further rotated in one direction. , by changing the amount of change in the BPM of the music for each unit rotation angle of the dials 341 and 346 in one direction from the first amount of change to the second amount of change, thereby changing the reproduction speed of the music for each unit rotation angle. Amounts may vary. Also, in this case, the amount of change may be changed from the second amount of change to the first amount of change. Further, the control unit 5 determines whether the dials 341 and 346 are rotated toward the housing 2 without being pressed down, or when the dials 341 and 346 are rotated toward the housing 2 while being pressed down. It is also possible to change the amount of change in BPM of music for each unit rotation angle of 341 and 346 and the amount of change in playback speed of music for each unit rotation angle. In addition, the control unit 5 determines whether the pressing force applied to the dials 341 and 346 in the direction toward the housing 2 is less than a predetermined value and when it is equal to or greater than the predetermined value. The amount of change in BPM of music and the amount of change in reproduction speed of music for each unit rotation angle may be changed.
　上記各実施形態では、制御部５は、ダイヤル３４１，３４６の回転速度が所定速度未満である間、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭの変化量を、第１変化量とし、ダイヤル３４１，３４６の回転速度が所定速度以上である間、ダイヤル３４１，３４６の単位回転角度毎の楽曲のＢＰＭを、第１変化量よりも大きい第２変化量とした。しかしながら、これに限らず、第２変化量は、第１変化量よりも小さい変化量であってもよい。 In each of the above embodiments, the control unit 5 sets the amount of change in the BPM of the song for each unit rotation angle of the dials 341, 346 as the first amount of change while the rotation speed of the dials 341, 346 is less than the predetermined speed, While the rotation speed of the dials 341, 346 is equal to or higher than the predetermined speed, the BPM of the music for each unit rotation angle of the dials 341, 346 is set to the second amount of change larger than the first amount of change. However, without being limited to this, the second amount of change may be a smaller amount of change than the first amount of change.
　上記各実施形態では、音響制御装置１，１Ａは、ダイヤル３４１，３４６の回転加速度を検出する検出部３４２を備えるとした。そして、制御部５は、検出部３４２によって検出されるダイヤル３４１，３４６の回転加速度に基づいてダイヤル３４１，３４６の回転速度を算出するとした。しかしながら、これに限らず、ダイヤル３４１，３４６の回転時間及び回転角度に基づいて、ダイヤル３４１，３４６の回転速度を算出してもよい。 In each of the above embodiments, the acoustic control devices 1 and 1A are provided with the detection section 342 that detects the rotational acceleration of the dials 341 and 346. Then, the controller 5 calculates the rotational speed of the dials 341 and 346 based on the rotational acceleration of the dials 341 and 346 detected by the detector 342 . However, the rotation speed of the dials 341 and 346 may be calculated based on the rotation time and rotation angle of the dials 341 and 346 without being limited to this.
　上記各実施形態では、制御部５は、ダイヤル３４１，３４６が第１回転方向としての時計回りに回転されると、楽曲のＢＰＭ及び再生速度を増加させ、ダイヤル３４１，３４６が第１回転方向とは反対方向である反時計回りに回転されると、楽曲のＢＰＭ及び再生速度を減少させるとした。しかしながら、これに限らず、制御部５は、ダイヤル３４１，３４６が反時計回りに回転されると、楽曲のＢＰＭ及び再生速度を増加させ、ダイヤル３４１，３４６が時計回りに回転されると、楽曲のＢＰＭ及び再生速度を減少させてもよい。また、制御部５は、ダイヤル３４１，３４６が時計回り及び反時計回りのうち一方の方向に回転されたときのみ、楽曲のＢＰＭ及び再生速度を増加又は低減させる構成としてもよい。 In each of the above embodiments, when the dials 341 and 346 are rotated clockwise as the first rotation direction, the control unit 5 increases the BPM and playback speed of the music, and rotates the dials 341 and 346 in the first rotation direction. is rotated in the opposite direction, counterclockwise, to decrease the BPM and playback speed of the song. However, the present invention is not limited to this, and the control unit 5 increases the BPM and playback speed of the music when the dials 341 and 346 are rotated counterclockwise, and increases the music playback speed when the dials 341 and 346 are rotated clockwise.
