2. Description of the Related Art Recently, an increasing number of people are interested in the calories they have consumed and consumed. This is because if you do not exercise according to the calories you have ingested, excess calories will accumulate in your body as fat, leading to obesity and poor health. Due to this tendency, the amount of calorie intake has been increased in recent years in the menus of restaurants and the introduction section of dishes. In addition, the exercise equipment in the gym is designed to notify the calories burned by the exercise. In order to maintain one's health, it is extremely important to accurately understand the calories consumed and consumed.

By the way, singing a song in karaoke consumes a considerable amount of calories. This is due to abdominal breathing when singing a song, because when the song is sung, the diaphragm is moved up and down violently to inhale and exhale a large amount of air into the lungs. The energy consumed here is equivalent to the amount of exercise that is consumed when running several tens of meters, and it is said that if you sing seriously, the amount of energy that is consumed when running 100 m is reached.

[0004]

[Problems to be Solved by the Invention] However, conventionally, even if a song was sung in karaoke, it was not possible to know how much calories were consumed by oneself. The effect of calorie consumption by singing a song was not well known. If you know your calorie consumption when you sing a song at karaoke, you can understand the calorie consumption effect of karaoke and use it for calorie management and dieting.

Therefore, the present applicant previously applied for a karaoke device having a function of estimating the calories consumed by singing and notifying the user. This device checks the user's singing voice volume input through the microphone,
The amount of exercise in the diaphragm is measured to estimate calorie consumption.

However, while singing a song, the user may unknowingly be waving his arms or legs in accordance with the accompaniment music, singing or dancing with choreography. is there. Such a physical movement of the user also corresponds to a physical exercise and consumes energy. In order to more accurately estimate the amount of calories consumed by the user while singing a song, it is better to reflect the energy consumption by these physical actions.

It is an object of the present invention to provide a karaoke apparatus which estimates the calorie consumption by uttering and also informs the singer of the calorie consumption by singing and dancing. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS === Basic Configuration and Operation of Karaoke Device === An embodiment of a karaoke device according to the present invention is shown in FIG. The central control unit 6 including the CPU, RAM, and ROM of the karaoke device 2 receives the music request from the user from the remote control transmitter 8 or the operation panel 12 through the remote control receiver 10 or the operation input interface 14, and then the data storage device. The karaoke data (including MIDI data) of the music piece is acquired from 4 and processed for performance, and the karaoke accompaniment music of the music piece is generated through the synthesizer 16. Also, the lyrics image that matches the signal of the accompaniment music is generated through the video control unit 24. The karaoke accompaniment music thus generated is mixed with the microphone 2 by the mixing amplifier 18.
It is synthesized with the singing input from 0 and is output as sound from the speaker 22. In addition, the generated lyrics image has DV in the background.
The output images from the D player 25 are combined and output to the display 28.

=== Voice Energy Estimating Means === As a preprocessing system of the voice energy estimating means, a low-pass filter 30a for extracting the volume level of the singing voice signal from the microphone 20 and this filter 30a.
A / is converted to digital and supplied to the central control unit 6 A /
And a D converter 30b.

During the performance period of the requested song, the central control unit 6 sequentially samples and integrates the volume level information of the singing voice from the A / D converter 30b, and the data correlated with the energy consumption amount due to the vocal movement of the singing voice. To calculate. In other words, singing louder requires exercising the abdominal muscles for vocalization more vigorously, and therefore energy consumption by vocalization increases as loudly sings. By accumulating the output levels of the microphones 20, data corresponding to the singing volume can be obtained, and the data is associated with the energy consumption amount due to the vocalization of the singing.

=== Dynamic Energy Estimating Means === The scaffold sensor of this embodiment is installed on the floor of a karaoke store and a stage plate 34 on which a singer stands is placed.
The pressure sensor 36 is sensitive to the load applied to the stage plate 34, and the sensor signal processing circuit 32 processes the output signal of the pressure sensor 36. The pressure sensor 36 is a piezoelectric sensor and is attached between the four corners of the lower surface of the stage plate 34 and the very short legs 35. The sensor signal processing circuit 32 averages the output values of the four pressure-sensitive sensors 36, digitally converts them, and supplies them to the central control unit 6. The scaffolding sensor of this example is connected to the karaoke apparatus main body 2 including the central control unit 6 and the like by a cable.

During the performance period of the requested song, the central control section 6 sequentially samples the motion detection signals from the scaffold sensor from the sensor signal processing circuit 32 and integrates them to obtain data that correlates with the energy consumption amount due to the dynamism associated with singing. To calculate. In other words, when the singer makes a sudden movement on the stage plate 34, the load change caused by the movement is detected by the pressure-sensitive sensor 36. Therefore, by accumulating the output levels of the sensor 36, the singer's movement can be changed. The data corresponding to the intensity can be obtained, and the data is associated with the energy consumption by the singers' dynamism.

The data processing method for estimating the energy consumption amount from the output of the microphone 20 and the data processing method for estimating the energy consumption amount from the output of the scaffold sensor are based on actual measurement values collected from as many testers as possible. , Appropriately determined so that the most appropriate value can be estimated.

=== Calorie Consumption Calculation Output Means === In this embodiment, it is assumed that the estimated value of the calorie consumption due to singing the requested song is displayed on the display 28 at the performance end time of the requested song. The central control unit 6 calculates the data correlated with the above-mentioned energy consumption amount by the vocal energy estimating means and the dynamic energy estimating means during the performance of the requested song. Then, at a predetermined timing near the end of the performance, the estimated value of energy consumed by the song converted into calories based on the data obtained by the energy estimation means of the two systems is obtained and displayed on the display 28 for an appropriate period. The estimated value to be displayed is the total value of the calorie consumption amount due to the vocal movement of the user and the calorie consumption amount due to the dynamic movement. The estimated value is displayed so as not to disturb the lyrics display. In addition, the following items should be implemented when displaying the estimated value. For example, "calorie consumption ○○○ kcal! Message such as ”is added. The calorie consumption is represented using a chart so that the user can easily understand it. The calorie consumption due to vocalization and the calorie consumption due to dynamism are individually displayed. The standard calorie consumption is also displayed.

=== Other Embodiments === The energy consumption due to the dynamism associated with the singing can also be associated with the data obtained by detecting the vibration displacement of the scaffold portion of the singer. That is, a vibration sensor is provided at each corner of the stage plate 34 instead of the pressure sensor 36, and each sensor detects the vibration displacement of the stage plate 34.
Data corresponding to the intensity of rocking of the singer can be obtained and can be associated with the energy consumption. In estimating the energy consumption due to the singer's movement based on the output of the scaffold sensor, it is possible to improve the accuracy by incorporating the weight of the singer as a calculation parameter. To implement this method,
As a process before singing, a process of measuring the load (weight) of the singer in a stationary state by a scaffold sensor (pressure sensor) may be set.

[0019]

According to the karaoke apparatus of the present invention,
The calorie consumption by vocalization by measuring the singing volume of the singer and the physical activity of the singer when singing are captured and the calorie consumption by this exercise is calculated, so that the user can obtain more accurate calorie consumption. I can inform you. Therefore, even when the user sings while choreographing or dancing, the user is informed of the calorie consumption reflected in them. Therefore, the user can know the exact amount of calories consumed by singing, and can use it for health management and diet.
