PROBLEM TO BE SOLVED: To provide a beam direction setting device capable of setting a beam direction to an optional position desired by a user.SOLUTION: A beam direction setting screen displays a room inside image 10 corresponding to a bird's eye view of a rectangular room inside space and displays a speaker device image 11 corresponding to a speaker device 100 on a front face of the room inside image 10. When the user touches a predetermined position, a CPU 401 receives the designation of a listening position via a touch panel 402. Namely, receives the position touched by the user within the room inside image 10 as the listening position. The CPU 401 calculates an angle of the touch position relative to a front face of the speaker device 100 using coordinates of the touch position and center coordinates of the speaker device image 11. The calculated angle becomes a direction in which a beam should be output. The CPU 401 transmits the calculated angle value to the speaker device 100 as information indicating the beam direction. Further, the CPU 401 changes the beam direction on the basis of the calculated angle value and displays the changed beam direction.SELECTED DRAWING: Figure 2 |
