DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electronic metronome according to the present invention will be described below with reference to the drawings.

FIG. 1A is an explanatory view showing one embodiment of an electronic metronome according to the present invention, and shows a basic configuration of a surface portion of the electronic metronome 1.

On the surface of the main body of the electronic metronome 1, there is provided a rotary switch 2 having a plurality of contacts and made of an annular body. A push button switch 3 having contacts is provided, and a liquid crystal display 4 and a speaker unit 5 are provided.

The electronic metronome 1 generates an electronic sound corresponding to the set time signature and tempo, and has a reference sound generation function, a pitch shift function for finely adjusting the reference sound frequency, and a tap measurement function. .

FIG. 2 shows the basic configuration of the inside of the electronic metronome 1. The rotary switch 2, the push button switch 3, the liquid crystal display 4 and the speaker unit 5 are each basically composed of a microprocessor or the like. The metronome function, the reference sound generation function, the pitch shift function for finely adjusting the reference sound frequency, the tap measurement function, and the like are realized by the control device 6. .

In such an electronic metronome 1,
The rotary switch 2 is used to switch between a beat setting mode A, a reference sound generation mode B, a pitch shift setting mode C, and a tap measurement mode D, and to change a setting of an electronic sound generation tempo.

The push-button switch 3 is turned on by pressing the surface toward the inside of the main body, and is used for selecting predetermined data corresponding to each mode selected by the rotary switch 2. When switching to the tap measurement mode D is performed by the rotary switch 2, it is used to input data necessary for tap measurement. In the present embodiment, the push button switch 3 is used. However, the present invention is not limited to this. Any switch that can input a pulse signal to the control device 6 may be used.
Further, the arrangement of the push button switch 3 is not limited to the inside of the annular portion. For example, the push button switch 3 may be provided at a position separated from the rotary switch 2 or on the outer periphery of the rotary switch 2.

On the other hand, the liquid crystal display 4 displays the operation contents of the modes and predetermined data in each mode.

For example, when the rotary switch 2 is switched to the beat setting mode A, the operation contents of the mode as shown in FIG. By pressing the push button switch 3, the control device 6 controls the cursor 4a so that the cursor 4a is sequentially moved and displayed. For example, the beat data at the position of the cursor 4a is recognized as the selected data. .

The speaker unit 5 emits an electronic sound or a reference sound according to the set time signature and tempo.

Here, an example of the operation procedure of the electronic metronome 1 configured as described above will be described with reference to the flowchart of FIG.

First, when the power is turned on, before proceeding to step S1, the control device 6 sets initial data such as time signature and tempo.

In step S1, based on the signal from the rotary switch 2, the control device 6 determines which mode is selected.

When the mode is not one of the modes A to D, an electronic sound is generated according to the initially set time signature and tempo, and functions as a metronome.

At this time, the setting change of the tempo of the electronic sound in step S2 is appropriately performed by turning the rotary switch 2.

When the time signature setting mode A in step S3 is selected, the time signature data is selected in step S4.

The time signature data is selected by displaying the time signature data in a predetermined range on the liquid crystal display 4 and pressing the push button switch 3 to sequentially select the cursor 4a.
Is moved to the position of the desired data value.

In the case where the setting of the beat data is completed and the function as the above-mentioned metronome is again performed, an electronic sound corresponding to the set beat is emitted from the speaker unit 5 here.

The reference sound generation mode B in step S5
Is selected, a preset reference sound is emitted from the speaker unit 5.

Here, when the reference sound is changed and set to a desired reference sound, reference sound data is selected in step S6.

The selection of the reference sound data is performed by, similarly to the case of selecting the time signature data, displaying the reference sound data in a predetermined range on the liquid crystal display 4, and pressing the push-button switch 3 while watching this. , So that the cursor 4a
Is moved to the position of the desired data value.

When the setting of the reference sound data is completed, a reference sound corresponding to the set data value is emitted.

When the pitch shift setting mode C in step S8 is selected, a preset reference sound is emitted from the speaker unit 5, and pitch shift data is selected in step S8. As a result, the frequency of the reference sound changes subtly in real time.
While listening to this subtle change in sound, a desired frequency is selected.

The selection of the pitch shift data is the same as the above-described selection of the beat data and the selection of the reference sound data.

Further, when the tap measurement mode D in step S9 is selected, tap input in step S10 is performed.

Here, tap input means that the push button switch 3 is hit by hand at a constant tempo. By doing so, the number of hits per unit time is measured by the tap measurement function provided in the electronic metronome 1, and the measurement result is displayed on the liquid crystal display 5.

As described above, according to the present embodiment, the setting of the time signature setting mode A, the reference sound generation mode B, the pitch shift mode C and the tap measurement mode D of the electronic sound, and the change of the setting of the electronic sound generation tempo are performed by the multiple contacts. Rotary switch 2
By selecting predetermined data corresponding to each mode selected by the rotary switch 2 and performing tap input necessary for tap measurement by the push button switch 3, the configuration of the switch can be reduced as compared with the related art. The electronic metronome 1 can be simplified, and the electronic metronome 1 can be narrowed.

Further, since the push button switch 3 only needs to have a single contact, a more simplified switch can be used, and even if a tap measurement function is added, the push button switch 3 can be used. Since it can be used for tap input, a new switch for tap measurement is not required.

Further, by using the rotary switch 2, it is possible to easily cope with the case where a large number of contacts are required, and by arranging the push button switch 3 inside the annular portion, the structure of the electronic metronome 1 can be improved. Further simplification and narrowing can be achieved.

Further, since the liquid crystal display 5 is provided, operations such as data selection can be performed while watching the liquid crystal display, so that the operability of the electronic metronome 1 can be improved.

As described above, according to the electronic metronome according to the present invention, the first switch is used to switch between the beat setting mode, the reference tone generation mode, the pitch shift mode, and the electronic tone. Is changed, and predetermined data corresponding to each mode is selected by the second switch, so that the configuration of the switch can be simplified and the electronic metronome can be easily narrowed. Can be achieved. Also,
Since the second switch is used for selecting predetermined data,
For example, if predetermined data is cyclically selected, the selection operation can be achieved with one contact, so that a more simplified switch can be used.

According to the electronic metronome of the present invention, even if a tap measurement function is added, a new switch for tap measurement is not required by using the second switch for tap measurement.

Further, according to the electronic metronome according to the present invention, when the first switch is a rotary switch, it is possible to easily cope with a case where a large number of contacts are required, and a push button switch is provided inside the annular portion.
