TECHNICAL FIELD OF THE INVENTION
The present invention relates to an electronic metronome.
[0002]
[Prior art]
In a conventional metronome, a method of changing a tone color or counting down the number of beats is mainly used to represent a strong beat and a weak beat in beat setting. In addition, there is one that displays the tempo with a circular LED (for example, see Patent Document 1).

[0004]
[Problems to be solved by the invention]
As a metronome that expresses the time signature, there are those that change the color of the LED that lights up at the timing of the strong beat or the tone from the speaker, but the strong beat that is the head of the count in a series of beats The only way to know the timing is to have the user count the beat or, if the metronome is implemented as a function, look at a digital display that automatically counts down. For this reason, the user must process the two operations of counting the time signature and playing the instrument in parallel, which tends to make mistakes such as a decrease in concentration, wrong counting, and wrong playing. Was.
[0005]
[Means for Solving the Problems]
In order to solve such a problem in the related art, the present invention uses a pattern similar to a clock face as a display method, so that in a set series of beats, the strength of the next count can be increased. An electronic metronome characterized in that the timing of a beat can be easily visually recognized as an analog quantity.
[0006]
In order to solve the above problems, the present invention provides a beat setting input unit, a circular timing display unit composed of a plurality of fan-shaped patterns, a control unit that outputs a signal based on the input setting, and a control circuit. It has a speaker unit for outputting a signal from the device, and displays the beat count as an analog amount in a schematic pattern. This makes it easier to recognize the number of beats than performing the two operations of playing the instrument and counting down the beat in parallel. This is useful for educating young children who still lack musical knowledge, because the time signature can be recognized as part of the picture, not as digital numbers.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the configuration and operation of the present invention will be described in detail.
[0008]
FIG. 1 shows a block diagram of an electronic metronome of the present invention, and the connection and operation will be described.
[0009]
The beat setting input unit 1 is a unit for inputting a user operation such as selecting a beat, and the input set value is sent to the control unit 2. The control unit 2 forms a signal in accordance with the beat setting value, and the signal is sent to the speaker unit 4 and the timing display unit 3, where the signal is generated by the speaker unit 4 and displayed on the timing display unit 3. The display unit 3 includes an LCD display device, an LED display device, and the like.
[0010]
Next, an electronic metronome shown in FIG. 2 will be described as an embodiment.
[0011]
In this electronic metronome, it is possible to input and set the time signature, and when the setting dial 5 is slid one by one in the left direction, the time signature setting is decremented by one to time signature 1. By sliding one at a time to the right, the time signature setting is increased by one up to time signature 6.
[0012]
For example, when the setting dial 5 is set to beat 4, the beat in the control unit 2 is one cycle of beat 1 → beat 2 → beat 3 → beat 4; Then, the weak beat is output to the speaker 6 as a signal at a timing corresponding to the tempo, and a sound is emitted. At the same time, "1" is displayed on the beat display segment 8 as the display of beat 1, and in a circular segment composed of a plurality of fan-shaped patterns, 45 from 12:00 to 3:00, which is the analog display of the hands of the analog watch. The fan-shaped beat 4 segment display 12 of the degree is turned on.
[0013]
FIG. 3 shows a sector pattern displayed on the segment. As a display of the beat 2, "2" is displayed as the display of the beat 2 in the time signature display segment 8, and 45 degrees of the fan-shaped segment from 3:00 to 6:00 are lit on the circular segment. As a display of the beat 3, "3" is displayed as the display of the beat 3 in the time signature display segment 8, and a 45-degree fan-shaped segment from 6:00 to 9:00 lights on the circular segment. As the display of the beat 4, "4" is displayed as the display of the beat 4 in the time signature display segment 8, and a 45-degree fan-shaped segment from 9:00 to 12:00 is lit on the circular segment. In this way, one cycle of the time signature is replaced by an analog quantity which is the area of a 360-degree circle, and the count of the time signature is displayed by four 45-degree fan patterns.
[0014]
Similarly, when the setting dial 5 is set to the time signature 5, the time signature 5 segment display 13 is illuminated so as to sequentially draw a circle as in the case of the time signature 4, and the time signature is indicated by an analog amount. When the set time signature is 2, a semi-circle time signature 2 segment display 10 from 0 to 180 degrees is displayed so as to rotate by 180 degrees around the center of the circle, and when the set time signature is 3, 0 degree is displayed. A 3-segment display 11 is displayed so as to rotate by 120 degrees around the center of the circle. When the set time signature is 5, a fan-shaped time signature 2 from 0 to 72 degrees is displayed. The segment display 13 is displayed so as to be rotated by 72 degrees around the center of the circle.
[0015]
In addition, by providing a switch that can change the lighting pattern of the segment, a function that allows the user to select a lighting pattern that is easily recognizable among the lighting patterns 14, 15, and 16 in the case of the time signature 4 can be provided. . One fan-shaped four-segment display 12 is illuminated as if it is rotated around the center of the circle, or a white circle is illuminated such that the four-segment display 12 is sequentially filled, or conversely a black circle. The lighting process is performed so as to clear the circle of, so that the user can select a display pattern that is most easily recognized as a picture.
[0016]
In this way, the time signature is displayed not only by counting the number, but also by visually indicating the time signature with a plurality of fan-shaped patterns as a circular analog quantity imitating an analog clock, so that the time signature can be counted as a digital number count Without having to do this, even an infant can easily follow the flow of beats.
[0017]
In the above description, the setting dial is configured by a knob that moves in parallel, but is not limited thereto, and may be realized by a dial, a push button, or the like. In addition, although the segment is circular, the shape is not limited to this, and a polygonal shape or the like may be used as long as the shape is easy to recognize.
[0018]
【The invention's effect】
According to the present invention, as described above, the timing of the electronic metronome is displayed as an analog quantity on a chart similar to an analog clock, so that the timing of a strong beat as a head of the count in the beat and the beat of one cycle can be obtained. Progress can be intuitively understood visually.
