Description

  The present invention relates to a karaoke system for detecting abdominal breathing at the time of singing a karaoke song and providing information related to abdominal breathing necessary for the improvement of singing to a user.

  Breathing is broadly classified into chest breathing and abdominal breathing, the former is mainly breathing due to contraction of the intercostal muscles, and the latter is breathing mainly performed by raising and lowering the diaphragm. Singing with abdominal breathing makes it possible to sing very well because of the sharpness of the singing sound and the volume of the voice increases, and karaoke that wants to practice actively incorporating abdominal breathing to improve singing ability There are many users.

  In abdominal breathing, air is put into the abdomen during the inhalation process to raise the diaphragm, so the abdomen inevitably swells. On the other hand, when singing voice is emitted, exhaust is simultaneously performed and the swollen abdomen is retracted. Therefore, as a method for detecting abdominal breathing, it is preferable to detect the degree of expansion / contraction of the abdomen, thereby distinguishing between chest breathing and abdominal breathing and the number of breaths. By the way, by utilizing such physical changes of the body, a simple and lightweight abdominal respiration detection device is now conceived. For example, in Patent Document 1, there is an apparatus that is mounted between a human abdomen with a size of about a pedometer, and a movable body that contacts the abdomen detects and measures expansion and contraction of the abdomen by displacement of the movable body. It is disclosed.

In order to display comments according to the comparison results, it is possible to determine whether the user is singing while breathing properly with abdominal breathing, and improving the singing ability by abdominal breathing efficiently. There is an effect that can be derived.

  Hereinafter, the karaoke system of the present invention will be described with reference to a preferred embodiment. First, the functional block configuration diagram of the karaoke system of the present invention shown in FIG. 1 and the abdominal breath detection means shown in FIG. Based on the structural example diagram and the structural example diagram of the abdominal respiration detection method shown in FIG. 3, the overall system outline of the present invention and the configuration of (a) in claim 1 will be described in detail.

  As shown in FIG. 1, the karaoke system (1) of the present invention is mainly composed of abdominal respiration detection means (B1), abdominal respiration frequency recording means (B2), and abdominal respiration information display means (B3). Is attached to the karaoke performance device or incorporated in the device. Specifically, the abdominal respiration detection means (B1) detects the individual abdominal respiration of the user during the singing of the karaoke music and transmits a detection signal, and the abdominal respiration frequency recording means (B2) The detection signal is received and the number of receptions of the detection signal in the singing section for the song is recorded in a predetermined recording unit. The abdominal breathing information display means (B3) receives the number of receptions based on the recorded data. And / or the received number of times is compared with a preset number of times of reference based on the breath piece data of the music set in advance, and a comment corresponding to the comparison result is displayed at an appropriate timing.

  First, the abdominal respiration detection means (B1) will be described. As described above, a small and light simplified abdominal respiration detection device has been conceived at present, and the present invention is not particularly limited. Now, an embodiment will be described in detail.

  As shown in FIG. 2, the abdominal respiration detection means (B1) of the present embodiment mainly comprises a belt part (V) and abdominal respiration detection part (Bs) for wearing around the user's abdomen. The abdominal respiration detection unit (Bs) is provided in a portion corresponding to the buckle portion of a normal belt, and, like a normal buckle, a belt hole or a fixing hook for connecting one end of the belt to the user's abdomen. In addition to the above, a pressure detection sensor (piezoelectric element), a detection signal transmitter (Ir transmitter), and the like are provided. When the user wraps the belt part (V) around the abdomen and wears it with a belt hole and a fixing hook, when the user inflates the abdomen by abdominal breathing, the other end of the belt moves outward, A pressure detection sensor that senses the pressure displacement of the pair of telescopic springs that can be expanded and contracted corresponding to this movement generates a detection signal by a piezoelectric element, and an abdominal breathing frequency recording means (B2) by a detection signal transmitter. ) Is converted into an Ir signal and transmitted.

  As shown in FIG. 3, the abdominal respiration detection method detects abdominal respiration based on a pressure displacement unique to each user. Therefore, the abdominal respiration detection unit (Bs) includes an LCD (liquid crystal panel). A “abdominal respiratory pressure displacement reference setting” panel (Bp) having a GUI (Graphical User Interface) environment is provided, and when the user wears the abdominal respiratory detection means, the user first determines the number of measurements. (May be set in advance as a default), for example, 5 abdominal breaths are executed consciously and accurately with the setting of “5 times”, and the pressure displacement is measured. In this embodiment, the minimum detected pressure displacement is used, and the pressure displacement or more, that is, the abdominal expansion rate more than the abdominal respiration rate is regarded as the user's abdominal respiration. . In this embodiment, the minimum detected pressure displacement is adopted, but the present invention is not limited to this, and for example, an average detected pressure displacement of the number of samples may be used. The graph attached to FIG. 3 is a pressure displacement graph in the case of abdominal breathing, and the horizontal axis is the time axis and the vertical axis is the pressure axis. Count as abdominal breathing.

  Hereafter, the block diagram of the karaoke performance device shown in FIG. 4, the conceptual diagram of the detection signal reception frequency recording during singing shown in FIG. 5, and the example of comments based on the comparison of the reception frequency and the reference frequency shown in FIG. Based on the abdominal respiration information display example diagram shown in FIG.

  First, as shown in FIG. 4, the abdominal respiration frequency recording means (B2) and the abdominal respiration information display means (B3) in the karaoke system of the present embodiment are incorporated in the karaoke performance apparatus (P), It is controlled by the control means (3). When the abdominal respiration detection means (B1) detects each abdominal respiration of the user and issues a detection signal (Ir signal), the abdominal respiration frequency recording means (B2) is transmitted via the detection signal interface (2). Is received, and the number of times of reception of the detection signal in the singing section for one song is temporarily recorded in the abdominal breathing frequency data recording unit (d4) provided in the hard disk (5). The data recording unit (d4) may be temporarily recorded in a RAM (not shown) in the apparatus.

  The performance control means (4) detects from the performance data stored in the hard disk (5) based on the song-specific song section data (d1) included in the performance data in the song section or non-single section for each song. A control signal for discriminating the signal is transmitted to the abdominal breathing frequency recording means (B2), and the reception frequency of the detection signal of the non-singing section is deleted by this control signal, or the count during singing is not executed. Only the number of receptions of the detection signal in the singing section is recorded. FIG. 5 is a conceptual diagram of the detection signal reception frequency recording during the singing, but the composition of the performance music can be divided into a non-singing section in the prelude section, the interlude section, and the follower section and a singing section in the accompaniment section. These data are based on time series and are usually incorporated in the performance data of each musical piece. And when a user sings the said music, 1 waveform of abdominal type | mold breathing is recorded as 1 count, and the waveform count number of a song area is recorded as reception frequency.

  For distinguishing detection signals in the singing section or non-singing section for each song, in this embodiment, in order to set the singing section and the non-singing section, a method of detecting the presence / absence of the lyrics telop and the color change time of the lyrics characters Is adopted. That is, a case where the lyrics telop is displayed is set as a singing section, and a case where the lyrics telop is not displayed is set as a non-singing section. Alternatively, the lyrics telop is displayed with an expression that changes the color of the lyric character string from left to right at the timing of starting singing after displaying the lyric character string in a row. May be a non-singing section. The classification method is not particularly limited. For example, the display order of the lyrics character string in each karaoke song attached to the lyrics sequencer, the display / erase timing thereof, the start / end timing of color change of the displayed character string, etc. are described. The lyric rendering data may be used. Alternatively, it is possible to use a section data that accompanies the performance data, and this section data includes the prelude, the first singing section, the interlude, the second singing section, the interlude,. Data indicating the performance section is associated with the performance time series of the music, and can be arbitrarily set in MIDI (Musical Instruments Digital Interface) data, and if this is acquired, the singing section and the non-singing section can be detected. Can do.

  The hard disk (5) is provided with a reference frequency data recording unit (d2) by music and a comment data recording unit (d3) by comparison result, and the abdominal breathing information display means (B3) is abdominal breathing. Number of times data recording section (d4) Based on the recorded data, the number of times of reception and / or the number of times of reception is compared with the number of times of reference based on the breathing section data of a preset music, and a comment according to the comparison result Is displayed at an appropriate timing, for example, at a timing approximate to the display of the singing scoring result, the singing calorie consumption, or the like on a predetermined display means (D) as in the prior art.

  FIG. 6 illustrates a comment based on a comparison between the reception count and the reference count. The number of times of reference employs the number of breathing portions at a normal singing speed for each song, and is set in advance for each song. In the present embodiment, the comparison between the reference count and the reception count is made constant at a 100-minute ratio. For example, when the reception count is 30% or more higher than the reference count, specifically, the reference count is 40 and the reference count is When the number of times is 30, etc., “There are too many breathing in abdominal breathing. Let's adjust the breathing breathing longer” or more than 10% to less than 30% of the same, “breathing in abdominal breathing is a little "Let's adjust the breathing a little longer", or less than 10% less than 10% more, "I'm singing well with abdominal breathing" or less than 10% to less than 30%, Singing with a little bit of abdominal breathing, let ’s sing with a little more abdominal breathing ”or more than 30%,“ Insufficient singing with abdominal breathing. Let's have "or, comments in accordance with the comparison results are ready. Of course, the present invention is not limited to this, and it is preferable to prepare various comments such as singing guidance by abdominal breathing according to the degree.

  The abdominal breathing information display means displays the number of receptions and / or a comment corresponding to the comparison result on a predetermined display means, specifically a background image or lyrics telop at the time of karaoke performance. Is displayed on an LED of a karaoke remote control device attached to a display or a karaoke performance device. FIG. 7 illustrates the information display. For example, in (a), “abdominal number of times 24” is displayed, and the number of times of reception is displayed based on 24. In (b), only the comment corresponding to the comparison result is displayed without displaying the reception count. Furthermore, in (c), the number of receptions and a comment are displayed together. Thereby, it can be easily determined whether or not the user is singing while breathing appropriately with abdominal breathing.

  As described above in detail, according to the karaoke system of the present invention, the abdominal respiration detection means detects each abdominal respiration of the user and transmits a detection signal, and the abdominal respiration frequency recording means includes: The number of receptions of the detection signal in the singing section of the song is recorded, and the abdominal breathing information display means is based on the recorded data, and the number of receptions and / or the number of receptions and the breathing part of the song set in advance.
