metronome

Abstract

We provide a compact metronome that can display tempo using multiple visual display methods. [Solution] The metronome includes a display unit that includes three or more cells arranged in a row that light up and turn off; a user setting acquisition unit that acquires user settings; and a control execution unit that performs one of the following display controls according to user settings: a first display control that lights up or turns off the cells sequentially in a cycle from the cell at one end to the cell at the other end, and then from the cell at the other end back to the cell at the first end, in one beat; and a second display control that lights up or turns off the cells sequentially in a cycle from the cell at one end to the cell at the other end, in a half-cycle, in one beat, and then in a subsequent beat, lights up or turns off the cells sequentially in a cycle from the cell at the end that was just lit up or turned off to the cell at the opposite end, in a half-cycle.

6. A metronome according to claim 1, The control execution unit is, In the first display control, only the cell at one end is illuminated with light of a different color or brightness than the other cells, and in the second display control, both the cell at one end and the cell at the other end are illuminated with light of a different color or brightness than the other cells. metronome.

7. A metronome according to claim 1, The user setting that specifies the first display control is: The first display control includes information on whether to perform it on a strong beat or a weak beat, The control execution unit is, When the user setting indicates a strong beat, the cells are sequentially turned on or off in a cycle within one beat, from the cell at one end to the cell at the other end, and then back to the cell at the other end. When the user setting indicates a weak beat, the cells are sequentially turned on or off in a cycle within one beat, from the cell at one end to a predetermined return cell other than the other end, and then back to the cell at one end. metronome.

8. A metronome according to claim 7, The control execution unit is, The transition speed between the cells for turning on or off during the weak beat is accelerated or decelerated by a predetermined third acceleration, the magnitude of which is greater in the cells near one end and the folded cell, and smaller in the cells far from the one end and the folded cell. metronome.

9. A metronome according to claim 1, The user setting acquisition unit, The system can obtain the user's settings for specifying the third display control, The control execution unit is, If the user setting indicates the third display control, all the cells are turned on or off at one beat timing. metronome.

10. A metronome according to claim 9, The user setting that specifies the third display control is: The third display control includes information on whether to perform it on a strong beat or a weak beat, The control execution unit is, If the user setting indicates a strong beat, all of the cells are turned on or off at the timing of one beat; if the user setting indicates a weak beat, some of the cells are turned on or off at the timing of one beat. metronome.
