[Detailed configuration of effect adjustment section 57]
The adjustment knob 6 constituting the above-mentioned effect adjustment section 57 includes an operation knob main body 61, an adjustment position display marker 62, and a knob base 63, as shown in FIG. 2A.
The operation knob body 61 is rotatably held on the housing of the effect adjustment unit 57. The operation knob body 61 also includes a contact sensor 61A that detects whether or not the adjustment knob 6 is touched by the user.

The adjustment position display marker 62 is inserted into a notch formed in the operation knob body 61, and allows the user to visually confirm the amount of adjustment when the operation knob body 61 is rotated.
The knob base 63 is provided at the bottom of the operation knob body 61 and is supported so as to rotate in response to the rotation of the operation knob body 61. In addition, the knob base 63 has an outer circumferential end portion in the radial direction that protrudes outward from the operation knob body 61.
As shown in FIG. 2B, a rotation shaft 64 is provided at the rotation center of the knob base 63 , and the tip of the rotation shaft 64 is connected to a rotation resistor 66 provided on a circuit board 65 .

The effect adjustment unit 57 can accept two types of operations by the user. The first operation is an operation in which the user pinches the operation knob body 61 and rotates the adjustment knob 6 clockwise or counterclockwise. In this operation, the adjustment knob 6 stops rotating when the user releases his/her finger from the operation knob body 61 and ends contact with the operation knob body 61, that is, when the user's operation ends. This first operation is hereinafter referred to as a normal operation.
The second operation is an operation in which the user rotates the operation knob body 61 clockwise or counterclockwise as if flicking the axis of the top. This second operation is hereinafter referred to as a throw operation.

[Functional block diagram of DJ mixer 1]
FIG. 3 shows a functional block diagram of the control section of the DJ mixer 1.
A control unit 7 that controls the DJ mixer 1 controls input music data in response to the operation of the adjustment knobs of the various adjustment units shown in Fig. 1. The control unit 7 includes an acquisition unit 71, a rotation speed detection unit 72, a contact detection unit 73, a determination unit 74, and a playback control unit 75.

The acquisition section 71 acquires the outputs of the rotary resistor 66 and the contact sensor 61A in the adjustment knob 6 of the effect adjustment section 57. The output of the rotary resistor 66 indicates the rotation speed, which is the moving speed of the adjustment knob 6, which is the control, and the output of the contact sensor 61A indicates the presence or absence of the user's contact with the control knob body 61 of the adjustment knob 6, which is the control.
The rotation speed detection unit 72 detects the rotation speed of the adjustment knob 6 based on the output of the rotary resistor 66. The detection of the rotation speed is repeatedly performed at a predetermined cycle.
When the above-described normal operation is performed on the adjustment knob 6, the rotation speed becomes substantially zero at the point in time when the user releases his/her finger from the operation knob body 61 and ends contact with the operation knob body 61.

The contact detection unit 73 detects whether or not the user has touched the adjustment knob 6 based on the output of the contact sensor 61A. The detection of whether or not the user has touched the adjustment knob 6 is performed repeatedly at a predetermined cycle.
When the above-described normal operation is performed on the adjustment knob 6, the point at which the user's contact with the operation knob body 61 ends and the point at which the rotation speed of the adjustment knob 6 becomes zero approximately coincide with each other.

The determination unit 74 determines whether a normal operation or a throwing operation has been performed based on the rotation speed of the adjustment knob 6 detected by the rotation speed detection unit 72 and the presence or absence of the user's contact with the adjustment knob 6 detected by the contact detection unit 73.
The determination unit 74 determines that the operation has started when it detects a touch operation indicating the start of contact by the user with the adjustment knob 6, and determines that the operation has ended when it detects a release operation indicating the end of the contact. Then, it determines whether a normal operation or a throw operation has been performed according to the rotation speed at the time of determining the end of the operation based on the release operation.
If the rotation speed at the time of judging the end of the operation is slower than a predetermined first threshold, the judgment unit 74 judges that the above-mentioned normal operation has been performed on the adjustment knob 6. On the other hand, if the rotation speed at the time of judging the end of the operation is faster than a predetermined second threshold, the judgment unit 74 judges that the above-mentioned throw operation has been performed on the adjustment knob 6. Note that the first threshold and the second threshold may be the same value or different values. Furthermore, the first threshold and the second threshold may be designated by the user.

The playback control unit 75 performs different playback controls depending on the type of user operation determined by the determination unit 74. For example, the playback control unit 75 performs a first control when the determination unit 74 determines that a normal operation has been performed, and performs a second control instead of the first control when the determination unit 74 determines that a throw operation has been performed. Note that the second control may be a control different from the first control, or may include the first control and a third control different from the first control.
Any control may be performed by the playback control unit 75. For example, when the playback control unit 75 performs control to apply an effect to music data, if the determination unit 74 determines that a normal operation has been performed, a first effect is applied, and if the determination unit 74 determines that a throw operation has been performed, a second effect different from the first effect is applied instead of the first effect. Alternatively, if the determination unit 74 determines that a normal operation has been performed, the first effect is applied, and if the determination unit 74 determines that a throw operation has been performed, a third effect is applied in addition to the first effect.

With this configuration, the user can perform different controls with one operator by selectively operating the adjustment knob 6 of the effect adjustment unit 57. Also, by continuously performing normal operations and throwing operations, different controls can be performed without interruption with one operator. Note that a buffer may be provided in the control unit 7 to realize the reception of continuous operations.
The first to third effects are assigned in advance to the normal operation and the throw operation, respectively. The combination of the first to third effects may be set by the user, or a preferred combination may be stored in advance. Furthermore, the configuration may be such that the user can change a part or all of the preferred combination stored in advance and store it.

[Control method according to operation on effect adjustment unit 57]
FIG. 4 is a flowchart showing a control method executed by the control unit 7.
The rotation speed detection unit 72 detects the rotation speed of the adjustment knob 6 (step S11), and the contact detection unit 73 detects a release operation (step S12 YES).The judgment unit 74 then judges the end of the operation and determines what kind of user operation was performed on the adjustment knob 6 by comparing the rotation speed at the time of determining the end of the operation with a predetermined first threshold value Th1 (step S13).

When the determination unit 74 determines that the rotation speed at the time of the end of the operation is less than the predetermined first threshold Th1, that is, the rotation speed at the time of the end of the operation is slower than the predetermined first threshold Th1, and thus determines that a normal operation has been performed on the adjustment knob 6 (step S13 YES), the playback control unit 75 performs the first control assigned to the normal operation (step S14). Note that even if the contact detection unit 73 does not detect a release operation even after a predetermined time has elapsed (step S12 NO), the playback control unit 75 performs the first control assigned to the normal operation (step S14). On the other hand, when the determination unit 74 determines that the rotation speed at the time of the end of the operation is equal to or greater than the predetermined first threshold Th1, that is, the rotation speed at the time of the end of the operation is faster than the predetermined first threshold, and thus determines that a throw operation has been performed on the adjustment knob 6 (step S13 NO), the playback control unit 75 performs the second control assigned to the throw operation (step S15).
4 shows an example in which it is determined that a normal operation has been performed on the adjustment knob 6 when the rotation speed at the time of determining the end of the operation is slower than a predetermined first threshold Th1, and it is determined that a throw operation has been performed on the adjustment knob 6 when the rotation speed at the time of determining the end of the operation is faster than the predetermined first threshold Th1. However, it may also be determined that a normal operation has been performed on the adjustment knob 6 when the rotation speed at the time of determining the end of the operation is slower than the predetermined first threshold Th1, and it may be determined that a throw operation has been performed on the adjustment knob 6 when the rotation speed at the time of determining the end of the operation is faster than a predetermined second threshold Th2 (where Th2>Th1).
The control unit 7 repeats the processes from step S11 to step S15 to perform control in response to the user's operation on the adjustment knob 6.

In the control method described in Fig. 4, the control unit 7 performs processing based on the rotation speed and the presence or absence of contact, but processing may be performed taking into consideration the difference between the time when the adjustment position of the adjustment knob 6 reaches a predetermined position and the time when contact ends, in addition to the rotation speed and the presence or absence of contact. Fig. 5 is a flowchart showing another control method executed by the control unit 7.
In the example of FIG. 5, the rotation speed detection unit 72 detects the rotation speed of the adjustment knob 6 (step S21), and the determination unit 74 determines whether the adjustment position of the adjustment knob 6 is the center or a rotation end (step S22).
Even if a throw operation is performed on the adjustment knob 6, if the adjustment position of the adjustment knob 6 is operated to include the center, the rotation of the adjustment knob 6 due to the throw operation may be stopped by a click or the like, which is physical feedback. Similarly, even if a throw operation is performed on the adjustment knob 6, if the adjustment position of the adjustment knob 6 is operated to include the rotation end, the rotation of the adjustment knob 6 due to the throw operation may be stopped. In consideration of such a case, when the adjustment position of the adjustment knob 6 is the center or the rotation end, the determination unit 74 determines what kind of user operation has been performed on the adjustment knob 6, taking into account the difference between the time when the adjustment position of the adjustment knob 6 reaches a predetermined position and the time when the contact ends.

When the determination unit 74 determines that the adjustment position of the adjustment knob 6 is the center or the rotation end (YES in step S22), the determination unit 74 obtains the time T1 at which the adjustment knob 6 reaches the center or the rotation end (step S23).
Then, when the contact detection unit 73 detects a release operation (YES in step S24), the determination unit 74 determines that the operation has ended, and obtains the time T2 at which the operation ended (step S25).
Next, the determination unit 74 compares the difference between time T1 when the adjustment position of the adjustment knob 6 reaches the center or the end of rotation and time T2 when contact ends with a predetermined threshold Th3 to determine what kind of user operation has been performed on the adjustment knob 6. That is, by determining that the difference between time T1 and time T2 is equal to or greater than the threshold Th3, it determines that a normal operation has been performed on the adjustment knob 6 (step S26 YES), and by determining that the difference between time T1 and time T2 is less than the threshold Th3, it determines that a throwing operation has been performed on the adjustment knob 6 (step S26 NO).

When the determination unit 74 determines that the difference between time T1 and time T2 is equal to or greater than the threshold value Th3 and thereby determines that the normal operation has been performed on the adjustment knob 6 (step S26 YES), the playback control unit 75 performs the first control assigned to the normal operation (step S27). Note that even when the contact detection unit 73 does not detect the release operation even after a predetermined time has elapsed (step S24 NO), the playback control unit 75 also performs the first control assigned to the normal operation (step S27).
On the other hand, if it is determined that a throw operation has been performed on the adjustment knob 6 by determining that the difference between time T1 and time T2 is less than threshold value Th3 (step S26 NO), the playback control unit 75 performs a second control assigned to the throw operation (step S28).
In other words, the judgment unit 74 takes into consideration the difference between the time T1 when the adjustment position of the adjustment knob 6 reaches the center or the end of rotation and the time T2 when the contact ends, and if the difference between the time T1 when the adjustment position of the adjustment knob 6 reaches the center or the end of rotation and the time T2 when the contact ends is sufficiently short, it judges that a throwing operation has been performed rather than a normal operation.

If it is determined in step S22 that the adjustment position of the adjustment knob 6 is not the center or the rotation end, the same processes as in steps S12 and S13 in FIG. 4 are carried out in steps S29 and S30.
In other words, if it is determined that a normal operation has been performed on the adjustment knob 6 by determining that the rotation speed at the time of determining the end of the operation is slower than a predetermined first threshold value Th1 (step S30 YES), the playback control unit 75 performs a first control assigned to the normal operation (step S27), and if it is determined that a throw operation has been performed on the adjustment knob 6 by determining that the rotation speed at the time of determining the end of the operation is faster than a predetermined first threshold value (step S30 NO), the playback control unit 75 performs a second control assigned to the throw operation (step S28).
The control unit 7 repeats the processes from step S21 to step S30 to perform control in response to the user's operation on the adjustment knob 6.
Note that, of the control method described in FIG. 4 and the control method described in FIG. 5, either one of the control methods may be adopted, or both of the control methods may be adopted and switched depending on a user operation or a predetermined condition.

[Effects of the embodiment]
The DJ mixer 1 according to the present embodiment described above can provide the following effects.
The DJ mixer 1 is equipped with a rotation speed detection unit 72 that detects the rotation speed (movement speed) of the adjustment knob 6, which is an operator, in response to operation by the user, a contact detection unit 73 that detects whether the user has touched the adjustment knob 6, a determination unit 74 that determines whether the operation has ended based on the presence or absence of contact, and a playback control unit 75 that performs control according to the rotation speed (movement speed) at the time of determining that the operation has ended.
With this configuration, it is possible to determine what operation the user has performed with respect to one operator and perform different control according to the content of the user's operation. Therefore, operations that were previously performed using multiple operators can now be achieved with a single operator, which is expected to improve operability.

Furthermore, according to this embodiment, the playback control unit 75 performs a first control assigned to the adjustment knob 6, which is an operator, when the rotation speed (movement speed) at the time of judging the end of the operation is slower than a first threshold value, and performs a second control instead of the first control when the rotation speed (movement speed) at the time of judging the end of the operation is faster than a second threshold value. Therefore, by using different operations on the adjustment knob 6, the user can easily realize different controls based on the operation on one operator.

In addition, according to this embodiment, the second control includes the first control and a third control different from the first control. Therefore, the user can easily add a control based on an operation on one operator by selectively operating the adjustment knob 6.

Furthermore, according to this embodiment, the rotation speed detection unit 72 detects the rotation speed of the adjustment knob 6, which is a rotary operator, the contact detection unit 73 detects whether or not the user has touched the adjustment knob 6, and the playback control unit 75 determines whether or not the operation has ended based on the presence or absence of contact with the adjustment knob 6, and performs control according to the rotation speed at the time of determining the end of the operation. Therefore, different controls can be easily realized based on the operation of one rotary operator.

Furthermore, according to this embodiment, when the adjustment knob 6, which is an operator, is operated to a predetermined position (center or end of rotation), the playback control unit 75 performs control according to the rotation speed (movement speed), the presence or absence of contact, and the difference between the time when the adjustment knob 6 reaches the predetermined position and the time when the contact ends. Therefore, regardless of the adjustment position of the adjustment knob 6, the content of the user's operation can be determined more accurately.

In addition, according to this embodiment, a contact sensor 61A is provided. Therefore, with a simple configuration, it is possible to accurately detect whether or not the user is touching the adjustment knob 6.

Furthermore, according to this embodiment, the playback control unit 75 controls the application of effects to music data according to the rotation speed (movement speed). Therefore, in effect-related operations, improved operability can be expected when performing complex operations related to the type of effect and the degree of effect to be applied.

[Modifications of the embodiment]
In the above embodiment, the adjustment knob 6, which is a rotary operator, is used as an example of the operator, but the present invention is not limited to this example. For example, the present invention can be similarly applied to a linearly moving slide operator used for a fader or the like.

In the above embodiment, the determination unit 74 and the playback control unit 75 perform control according to the rotation speed (movement speed), the presence or absence of contact, and the difference between the time when the adjustment knob 6 reaches a predetermined position and the time when the contact ends when the adjustment knob 6 is operated including the center or the end of the rotation, but the present invention is not limited to this example. For example, the control may be performed taking into account the above-mentioned time difference only when the adjustment knob 6 is operated including the center, or the control may be performed taking into account the above-mentioned time difference only when the adjustment knob 6 is operated including the end of the rotation. Furthermore, depending on the configuration of the operator, the control may be performed taking into account the above-mentioned time difference when the adjustment knob 6 is operated including a predetermined position other than the center or the end of the rotation.

In the above embodiment, an example was shown in which the presence or absence of a user's contact with the adjustment knob 6 was detected based on the output of the contact sensor 61A, but the present invention is not limited to this example. For example, the present invention can be similarly applied to an operator that is a push switch. In this case, the contact detection unit 73 can obtain the same effect as the above embodiment by detecting the presence or absence of a user's contact with the operator depending on whether the push switch is pressed. In addition, by using a general-purpose part as the push switch, cost reductions can be expected and the differences in user operations on the push switch become clearer.

In the above embodiment, the playback control unit 75 performs control to apply an effect to music data as control according to the rotation speed (movement speed) at the time of determining the end of the operation, but the present invention is not limited to this example. The playback control unit 75 may perform control other than applying an effect to music data as control according to the rotation speed (movement speed) at the time of determining the end of the operation.

Furthermore, the audio equipment having the above-mentioned functions is not limited to the mixer described as one embodiment, but may be, for example, a DJ system in which a mixer and a player are integrated, a DJ controller with a mixer function, etc. Furthermore, the present invention is not limited to DJ equipment, but can also be applied to audio equipment such as general mixers and electronic musical instruments.
