DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus for outputting a singing input from a microphone together with karaoke accompaniment music.

[0002]

2. Description of the Related Art Humans consume calories taken from foods and the like through exercise. If you do not exercise enough for the calories you ingest, excess calories will accumulate in your body as fat and the like, leading to poor health, especially obesity. It is necessary to take a well-balanced calorie intake and moderate exercise corresponding to the calorie intake.

[0003] In recent years, an increasing number of people are interested in the amount of calories consumed by physical exercise. For example, wear a pedometer on your body all day and check your daily steps to see how much calories you can burn on foot. By grasping the calorie consumption due to the walking exercise, the calorie intake corresponding to the exercise amount is taken, and the calorie intake is intended to be consumed. The purpose is to link to calorie management and diet.

[0004]

By the way, when singing a song at karaoke, a considerable amount of calories are consumed for the singing. This is due to the abdominal breathing that occurs when vocalizing from the bottom of the belly, which consumes a large amount of energy when moving the diaphragm up and down violently to draw large amounts of air into and out of the lungs. It is said that the energy used here is equivalent to the amount of exercise consumed when running for several tens of meters, and, if seriously sung, reaches the amount of consumption consumed when traveling 100 m.

[0005] However, in the past, even when singing a song at karaoke, there was no way to know how much calories you were consuming. The effects of calorie consumption by singing songs have received little attention, and their dieting effects and health have been largely overlooked. If you know your calorie consumption when singing a song at karaoke, you can recognize the effect of calorie consumption by karaoke and use it for calorie management and dieting.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a karaoke apparatus capable of notifying the calorie consumption by physical exercise when singing a song at karaoke.

[0007]

In order to achieve the above object, a karaoke apparatus according to the present invention provides a karaoke accompaniment music and a singing input from a microphone, and outputs a lyric image in accordance with the progress of the karaoke accompaniment music. In a karaoke apparatus that outputs video, a singing input volume from a microphone is sampled at a predetermined time interval, and a volume integrating means for sequentially integrating each sample value, and a predetermined value calculated by the volume integrating means. A conversion means for converting the calorie consumption of the physical exercise by singing in accordance with the algorithm described above, and a notifying means for informing the user of the calorie consumption calculated by the conversion means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS ==== Basic Configuration and Operation of Karaoke Apparatus ==== FIG. 1 shows an embodiment of the configuration of a karaoke apparatus according to the present invention. The apparatus includes a karaoke database 2 storing a large number of karaoke data including accompaniment music data and lyrics drawing data in a MIDI format and the like, and a main computer 4 including a central processing unit (CPU). The main computer 4 sequentially reads, from the karaoke database 2, karaoke data corresponding to the tune requested by the user via the user interface 10 from the remote control transmitter 6, the operation panel 8, or the like, and outputs the karaoke accompaniment music via the sound control unit 12. Microphone 14
The sound is output from the speaker 16 together with the singing input from the speaker. Further, in synchronization with this, the lyrics image is output to the display 18 via the video control unit 20 as a video. The background image output from the background image supply unit 22 is synthesized and displayed on the background of the lyrics image on the display 18 through the image control unit 20. Further, the main computer 4 includes a display 18.
And other images and videos other than the lyric image can be appropriately controlled on the display screen.

==== Sampling Processing of Singing Input Signal from Microphone ==== This karaoke apparatus is provided with a sound volume detecting section 24 as a means for informing the calorie consumption of physical exercise by singing. The sound volume detection unit 24 includes, for example, an audio signal processing A-
It is composed of various audio signal processing circuits capable of sampling an audio signal, such as a D converter. Volume detector 2
A singing input signal from the microphone 14 is input to 4 and the singing input signal is sampled at predetermined time intervals. In this sampling process, the volume detection unit 24 performs a process of sequentially taking out the instantaneous value of the signal level of the singing input signal as a sample value at predetermined time intervals. The sampling interval is set to, for example, about 0.2 seconds. FIG. 2 shows an image of the sampling of the singing input signal. These sample values are
The sound is output from the volume detector 24 to the main computer 4.

==== Calculation of Calorie Consumption by Main Computer ==== The main computer 4 performs an arithmetic process of sequentially integrating sample values sent from the volume detector 24 during performance processing of karaoke data. . By integrating the sample values,
The total amount obtained by time-integrating the vocal volume level of the singer over the entire singing period is obtained.

Further, the main computer 4 performs a process of converting the integrated value calculated by the calculation process into a calorie consumption amount of the physical exercise by singing. In this embodiment,
A calculation process of multiplying the calculated integrated value by a calorie conversion coefficient is performed. Here, the calorie conversion coefficient represents the calorie consumption per unit utterance volume, and was obtained by actually measuring the calorie consumption relative to the utterance volume when a person having a standard physique sings normally. Things.
For the calorie consumption for the utterance volume, refer to Japanese Patent Application No.
As disclosed in -212136 and the like, the calculation was performed by measuring the amount of oxygen consumed by the person by singing with an oxygen consumption measuring device. Thereby, the calorie consumption based on the integrated value, that is, the total vocal volume of the singer can be calculated.

Therefore, if the user sings at a louder sound volume than usual, the calorie consumption increases. Also, if the user sings up to half of one song and skips the remaining singing parts, the calorie consumption will be halved. Also,
Even in the interlude part other than the singing part, if the user speaks out, the calorie consumption will increase accordingly.

The main computer 4 displays the calculated calorie consumption on the display screen of the display 18 to notify the user. The calorie consumption screen display may be performed in real time while performing the karaoke accompaniment music, or may be performed after the performance is completed. If you want to display the calorie consumption on the screen in real time during the performance, "Currently, your calorie consumption is XXkcal
is! ! Is displayed in a manner that is easy for the user to understand, using a message such as "." Also, if you want to display the calorie consumption on the screen after the end of the performance, "The calorie you consumed in this song is XXkcal!" ! ], And the standard calorie consumption and average value are displayed on the screen. In addition, the main computer 4 may output the calorie consumption amount by printing it on paper or the like by various output devices such as a printer as needed.

When the performance processing of the karaoke data is completed and the processing proceeds to the performance processing of the next music piece, the main computer 4 initializes the integrated value, and then starts the processing of calculating the calorie consumption of the next music piece. In this way, the calorie consumption for each song is calculated.

==== Other Embodiments ==== (1) The sample values are integrated, the integrated result is converted into the calorie consumption of physical exercise, and the converted result is further converted. The notification to the user may be made not by the main computer 4 but by the volume detector or other components.

(2) The conversion of the integrated value into the calorie consumption may be performed according to another algorithm other than the above-described calorie conversion coefficient set based on the oxygen consumption.

(3) It is also preferable that the approximate calorie consumption when a person having a standard physique sings the music is previously described in a table of contents such as an electronic table of contents. in this case,
The user can see songs with high calorie consumption and music with low calorie consumption by looking at these table of contents books, and can select and sing songs with high diet effects.

[0018]

According to the karaoke apparatus of the present invention, based on the singing input from the microphone, the calorie consumption by the vocal movements when singing can be calculated and notified to the user, so that the calorie due to the karaoke can be obtained. It can inform consumers of the effects of consumption and promote the health of karaoke to the general public, making it useful for diet and calorie management.

Further, based on the notified calorie consumption, the user can know his / her own utterance volume to know whether or not he sang at the correct breath and at the correct volume, which is used as a guide for judging whether or not he sang correctly. be able to. It can be used as a means to inform the correct singing method.
