Description

  The present invention relates to a system for recording a song sound input simultaneously using an air conduction microphone and a bone conduction microphone for a song sung by a user, and appropriately reproducing the recorded song sound.

  In the content of a conventional karaoke device, for example, the user's singing sound is scored using a scoring function installed in the karaoke device, or the user's own singing sound is listened later using a recording function. Can be written to a CD or DVD. Furthermore, since it is now possible to provide services using the Internet, for example, based on the score of music scored by user, this is displayed in a national ranking format, and users nationwide Users can participate by competing for scores with each other or uploading a recorded song sound file to the server to publish their singing voice on the homepage or by evaluating the song sound file by the judges. It has become possible to implement content such as auditions.

  By the way, at present, a bone conduction technique for picking up vibrations of bones when a user speaks by bringing them into contact with a person's cheek or jaw has been put into practical use. For example, bone conduction microphones applying this technology do not pick up noises such as environmental sounds and do not react to anything other than utterances, so they are used by people working in relatively noisy places such as construction sites and airfields. Yes. However, since the frequency characteristic of the sound input from this bone conduction microphone is different from the frequency characteristic of the sound input from the air conduction microphone that transmits sound by the conduction of air vibration that is generally used, for example, When using a bone conduction microphone in a mobile phone, the other party may feel uncomfortable because the user's voice sounds different from the usual voice. With respect to such a problem, in Patent Document 1, frequency spectrum analysis is performed on the sound input by a bone conduction microphone and a normal condenser microphone, and an equalizing characteristic that cancels the difference is set by an equalizer. Further, there is disclosed a technique for converting a voice inputted by a bone conduction microphone into a voice having substantially the same sound quality as that inputted by a condenser microphone and outputting the voice.

  In addition, as an application of this bone conduction technique to the field of karaoke, for example, Patent Document 2 discloses a technique for outputting singing assist information such as a guide melody by a bone conduction speaker attached to a karaoke microphone. Yes. In this patent document 2, the singing assistance output from the bone conduction speaker is not transmitted by vibrations that vibrate the singer's eardrum, but the bone conduction, that is, the user's cheekbones and jawbones are shaken, and the vibrations are A technology that directly communicates to the organ of the cochlea is disclosed. As a result, although the singing assist can be clearly heard for the singer, the singing voice of the singer who is preferably assisted in a secret manner is not heard because the singing assist cannot be heard for others other than the singer. It is possible to listen only to it.

  Now, the user may listen to the recorded content of the karaoke apparatus in order to confirm his / her recorded singing sound. At this time, the user usually feels that the singing sound that he / she actually sang is different from the recorded singing sound, and feels uncomfortable. This is because when the user listens to his / her own recorded voice indirectly, the sound, which is the vibration of the air, only enters the ear canal from the air, vibrates the eardrum, and eventually transmits air to the cochlea. On the other hand, when listening directly to your voice, in addition to air conduction, voice vibration is transmitted to the skull, to hear the voice through bone conduction that vibrates the bone and transmits the vibration to the cochlea. In other words, it is because the synthetic sound of air conduction and bone conduction is heard.

  By the way, there are many requests among singers using this recorded content to listen to the singing sound recorded with the same atmosphere and impression as the singing sound actually heard when singing. However, as described above, in reality, it can be heard that the singing sound is different from the recorded singing sound, and the user feels uncomfortable. In other words, the mechanism of the conventional karaoke apparatus cannot meet such a demand.

  Therefore, the present invention is a request by a singer who uses the recorded content of the karaoke device to listen to the recorded singing sound with the same atmosphere and impression as the singing sound actually heard when singing by himself. In response, an object is to provide a new recording / playback system that allows the singer to listen to the recorded singing sound without feeling uncomfortable.

  In view of the above problems, the present invention classifies and records the recording data of each singing sound simultaneously input from the air conduction microphone and the bone conduction microphone, and extracts the user's air conduction recording data and the bone conduction extracted from the data. The inventors have conceived that the above-mentioned problems can be solved by synchronously reproducing each combination of recorded data and recorded data.

  That is, the singing sound recording / playback system according to claim 1 of the present invention records the user's singing sound input simultaneously using the air conduction microphone and the bone conduction microphone for the song sung by the user, A system for appropriately reproducing recorded singing sound, and when a predetermined musical piece is sung, the user's singing sound simultaneously input from the air conduction microphone and the bone conduction microphone is converted into the air conduction recording data and the bone. It is classified as conduction recording data, each recording data is recorded in a predetermined recording data recording section, and the recorded air conduction recording data and bone conduction recording data are at least the user's air conduction recording data and bone conduction recording. A combination of data and recording data can be extracted, and control is performed so that each of the extracted combination recording data is synchronously reproduced.

  In addition, the singing sound recording / playback system according to claim 2 of the present invention refers to a user's singing sound input simultaneously using an air conduction microphone and a bone conduction microphone for a duet song sung by a plurality of users. It is a system for recording and appropriately reproducing the recorded singing sound, and when a predetermined duet music is sung, the singing sound of each user inputted simultaneously from the air conduction microphone and the bone conduction microphone, It is classified as air conduction recording data and bone conduction recording data, each recording data is recorded for each user in a predetermined recording data recording section, and each recorded user's air conduction recording data and bone conduction recording data is recorded. In addition to the air conduction recording data and bone conduction recording data of at least one user, the combination of the air conduction recording data of another user and the recording data can be extracted. And controls so that synchronous reproduction of each of the combination recorded data.

  Furthermore, the singing sound recording / reproducing system according to claim 3 of the present invention uses a composite microphone in which the bone conduction microphone is attached to a predetermined portion of the main body of the air conduction microphone and the two microphones are integrated in each of the above systems. It is characterized by.

  Therefore, according to the singing sound recording and reproducing system according to claim 1 of the present invention, when a predetermined musical piece is sung, the singing sound input simultaneously from the air conduction microphone and the bone conduction microphone is converted into the air conduction recording data and By classifying into bone conduction recording data and recording each recording data, it becomes possible to extract and record synchronously the user's air recording data and bone conduction data. Therefore, since the user can listen to the recorded singing sound as a synthesized sound of air conduction and bone conduction, the user can listen to the same atmosphere and impression as the actual singing sound without any discomfort.

  According to the singing sound recording / reproducing system of claim 2 of the present invention, when a predetermined duet music is sung, the singing sound simultaneously input from the air conduction microphone and the bone conduction microphone is converted into the air conduction recording data. By recording each recorded data into bone conduction data, it is possible to extract and synchronize and reproduce the air conduction recording data of the duet partner in addition to the user's air conduction recording data and bone conduction recording data. Become. Therefore, one of the duet users can listen to the recorded duet partner's singing sound with the same atmosphere and impression as when singing, and can also listen to his own singing sound as a synthesized sound of air conduction and bone conduction. It has the effect of being able to listen without a sense of incongruity with the same atmosphere and impression as the actual duet singing sound.

  Furthermore, according to the singing sound reproduction system according to claim 3 of the present invention, since the bone conduction microphone is attached to the predetermined part of the main body of the air conduction microphone, and the integrated composite microphone is used, the user separately uses a headset. It is possible to simultaneously input the singing sound to the air conduction microphone and the bone conduction microphone simply by singing in the same manner as using a normal karaoke microphone without wearing the karaoke microphone.

It is a block block diagram of the main components regarding the system of this invention. It is the figure which showed the form of this microphone. It is a figure which shows the combination at the time of recording of each recording data, and those reproduction | regeneration. It is a flow which shows the process which carries out synchronous reproduction | regeneration of air conduction and bone conduction recording data.

  In the following, an appropriate example of the singing sound recording / playback system of the present invention will be given. First, the “block configuration diagram of main components related to the system of the present invention” shown in FIG. 1 will be described.

  FIG. 1 is a block diagram of main components related to the system of the present invention. This system is built into the karaoke device (1), and can sing the user's singing sound simultaneously into the air conduction input unit (ma1, ma2) and the bone conduction input unit (mb1, mb2). It is composed of an air-bone conduction integrated microphone (M1, M2) (hereinafter referred to as "integrated microphone"). Here, various functional means of this system will be described. First, the two integrated microphones (M1, M2) connected to the main body of the karaoke apparatus (1) are respectively two systems of an air conduction input part (ma1, ma2) and a bone conduction input part (mb1, mb2). The singing sound signal input from each input unit is transmitted to a receiver (not shown) of the karaoke apparatus (1) by the same mechanism as that of a normal wireless microphone. Each microphone (M1, M2) is identified by a DCS code obtained by FM-modulating each carrier wave.

The karaoke apparatus (1) is composed of a central control means (2), an HDD (3), various functional means, and the like. The HDD (3) manages performance data, lyrics data, background video data, and the like. The music DB (DB) to be recorded is recorded, and the central control means (2) registers the music ID of the selected music in the performance reservation queue, and when the music is in the order in which it is played, The linked performance data is retrieved from the music DB, and the retrieved performance data is reproduced using the sound source (5) and output from the speaker (SP) via the mixing amplifier (11).

Next, the RAM (4) is provided with a microphone ID management unit (6) and a recording data recording unit (8). The microphone ID management unit (6) includes the integrated microphones (M1, M2). The microphone ID is transmitted when the power switch of each microphone is turned on, and the microphone ID received by the receiver (not shown) in the main body of the karaoke apparatus (1) is received. By recording in the microphone ID recording unit (6), the main body of the karaoke apparatus (1) and each integrated microphone (M1, M2) are paired.
The recorded data recorded by the microphone input sound recording means (7) is recorded in the recorded data recording section (8), and is input to the air conduction input section (ma1) of one integrated microphone (M1). The performed singing sound is recorded as air conduction recording data (Ra1), and the singing sound input to the bone conduction input unit (mb1) is recorded as bone conduction recording data (Rb1). The singing sound input to the air conduction input part (ma2) of the other integrated microphone (M2) is recorded as air conduction recording data (Ra2), and the singing sound input to the bone conduction input part (mb2) is bone conduction. Recorded as recorded data (Rb2). The recorded recording data is managed by associating the microphone ID with the song ID of the sung song in the recording data management table (see FIG. 3).

  Next, the recorded data combination extracting means (9) and the recorded data reproduction control means (10) record the recorded data in the recorded data recording section (8) when the reproduction of the recorded data is received from the user from a predetermined commander. The recorded data is extracted from the air conduction recording data (Ra1), the bone conduction recording data (Rb1), the air conduction recording data (Ra2), and the bone conduction recording data (Rb2) using the recording data combination extracting means (9). The necessary recording data is extracted in combination as appropriate. Then, the recorded data reproduction control means (10) refers to the music ID associated with each recording data extracted in combination from the recording data management table, and synchronizes the performance data of the music ID and each recording data. It controls to reproduce. Specifically, for example, when a user using a microphone (M1) wants to reproduce a singing with a duet partner of the microphone (M2), his / her own air conduction recording data (Ra1) and bone conduction recording data ( In addition to Rb1) and the other party's air conduction recording data (Ra2), the performance data is synchronously reproduced. Note that this synchronized playback is to play back each data with the same timetable. Air conduction recording data and bone conduction recording data are input simultaneously when singing. If so, both voices are reproduced in a completely synthesized state. Of course, the performance data is also reproduced at the same timing according to this time table. As a result, the user can listen to the recorded duet opponent's singing sound in the same atmosphere and impression as when singing, and can also listen to his own singing sound as a synthesized sound of air conduction and bone conduction. You can listen to the same atmosphere and impression as the duet singing sound.

  In the present embodiment, the performance data and each recording data are not simply synchronized and reproduced, but can be recorded on a portable information storage medium such as a predetermined CD or DVD. 12) is provided. Therefore, each piece of data can be written on the medium so that the performance data and each recording data are synchronously reproduced on the portable information storage medium.

  Next, the “diagram showing the form of the present microphone” shown in FIG. 2 will be described.

  This (a) integrated microphone configuration in FIG. 2 is a structure in which a supporting column incorporating necessary wiring is attached to the grip portion of the air conduction microphone input portion (ma1), and the bone conduction microphone input portion (mb2) is attached to the tip portion thereof. ) Is installed. This strut can be rotated to some extent with the grip joint as the center of the rotation axis, and a spring-like auxiliary strut that supports the strut while allowing this rotation is also provided at the center of the strut. It is possible to cope with the difference in the shape of the jaw. The figure shows a case where a user's singing sound is input simultaneously using this integrated microphone. Specifically, the air conduction microphone input unit (ma1) indicates a dynamic microphone, a condenser microphone, or the like that is normally used when a user sings music with a karaoke device, and sings music. Sometimes it is positioned near the user's mouth to pick up vibrations from the user's vocal cords and convert them into air voice signals. On the other hand, the bone conduction microphone input unit (mb2) picks up the vibration of the user's bone when singing music and converts it into a bone conduction signal. When the user sings, the bone conduction microphone input unit (mb2) is inevitably joined so as to be in contact with the user's chin when the air conduction microphone input unit (ma1) is brought close to the mouth. Yes. This is a situation in which a user normally uses a karaoke microphone, taking into consideration the points that do not cause discomfort or obstruction when singing music, and are easy to pick up bone vibration during singing.

  Next, (b) the form of the separate microphone uses a separate microphone in which the air conduction microphone and the bone conduction microphone are separate, and enables the user's singing sound to be input simultaneously. As the air conduction microphone input unit (ma2), a dynamic microphone, a condenser microphone, or the like that is normally used is used similarly to the integrated microphone, and a user's singing sound is input and converted into an air sound signal. The bone conduction microphone input part (mb2) of the separate microphone (M2) is attached to the headset. At the time of singing, when the user wears the headset connected to the bone conduction microphone control unit (C), the bone conduction microphone input unit (mb2) comes into contact with the cheek of the user, and the vibration of the cheekbone is picked up. Is. If the user sings with the air conduction microphone in the state where the headset is worn in this way, the user's singing voice can be input simultaneously. In this embodiment, the air conduction and bone conduction composite microphone of the above-described form is used. However, the present invention is not limited to this, and the bone transmission microphone may be an earphone type, and the user's singing sound is simultaneously recorded. Other forms may be used as long as input is possible.

  Next, the present invention will be described in further detail with reference to “a diagram showing recording of each recording data and a combination at the time of reproduction” shown in FIG.

  The recording data management table (T) shown in the schematic diagram of the recording data management table in FIG. 3 is provided in the recording data recording unit (see FIG. 1), and the air recorded by the microphone input sound recording means. Conduction recording data, bone conduction recording data, and microphone ID and music ID linked to these recording data are recorded. That is, as the configuration requirements, a “No” field (f1) indicating a management number, a “song ID” field (f2) indicating a song ID of a song sung by the user, and a microphone ID of a microphone used at the time of singing "Microphone ID" field (f3) indicating, "Air conduction recording data" field (f4) indicating data recording the singing sound input to the air conduction microphone input section, and the bone conduction microphone input section For example, when a duet song is sung, two microphone IDs and two microphone IDs and 2 are recorded. A set of air conduction recording data and bone conduction recording data will be recorded.

  Next, (b) recording data combination in FIG. 3 is recorded in the recording data management table (T) by the recording data combination extracting means when recording data reproduction from a singer is accepted. It is an example when recording data is extracted and combined.

First, (b1) “Solo song” recording data combination means, for example, accepting reproduction of recording data of solo song with song ID “***** 1” from a singer using microphone ID “M1” In this case, the air conduction recording data and the bone conduction recording data at the time of the singing are combined. Specifically, the air conduction recording data “Ra1” and the bone conduction recording data “Rb1” corresponding to the microphone ID “M1” are obtained. Combined.
Next, (b2) a combination of recording data of duet music is a user of microphone ID “M1” who sang a duet music, for example, music ID “***** 5” or of microphone ID “M2”. When the reproduction of the recording data is accepted from one of the users, the recording data is combined mainly with the microphone ID of the microphone to which the user's singing sound is input. That is, when a user who uses the microphone ID “M1” is mainly used as a combination of the duet music, the air conduction recording data “Ra1” of the user who uses the microphone ID “M1” is recorded as bone conduction recording. Each recording data of the data “Rb1” and the air conduction recording data “Ra2” of the microphone ID “M2” as a duet partner are combined. Conversely, when the user who uses the microphone ID “M2” is mainly used, each of the air conduction recording data “Ra2” and the bone conduction recording data “Rb2” of the user who uses the microphone ID “M2”. The recorded data and the air conduction recorded data “Ra1” of the microphone ID “M1” as a duet partner are combined.
Then, each recording data extracted in combination is synchronously reproduced together with the performance data corresponding to the music ID by the recording data reproduction control means.

  Next, the process from the recording of the user's singing sound to the synchronized reproduction of each recording data and performance data using the “flow showing the process of synchronously reproducing the air conduction and bone conduction recording data” shown in FIG. Will be described.

  The process in the case of (a) solo music in FIG. 4 shows the flow from the recording of the singing sound of the solo music to the synchronized playback of each recording data and performance data of the air conduction recording data and the bone conduction recording data. It is a thing. First, the user registers and registers the selected music piece, and recording starts when the reserved music piece starts playing (S1). That is, the singing sound input simultaneously to the air conduction and bone conduction microphones from the start of the performance is recorded (S2). Then, when the performance is finished, the recording of the singing sound is finished (S3), and the recorded data is classified into the air conduction recording data and the bone conduction recording data and recorded in the recording data recording section of the RAM (S4). . Next, when the recording data is received by the user (S5), the registered air conduction recording data and bone conduction recording data are combined and extracted (S6). Further, the performance data linked to these are synchronously reproduced (S7). If the recording data is not received by the user, the process returns to the process before the reserved music is played.

  Next, (b) processing in the case of duet music in FIG. 4 shows a flow from recording the singing sound of the duet music to synchronously reproducing each recording data of the recorded singing sound and the performance data. Is. First, the microphone ID used by each user (if a wireless microphone is distinguished by a frequency channel, if a wireless microphone is identified by a connection jack) is recognized in advance by the karaoke device. When the selected music is reserved and registered, and the performance of the reserved music starts, the recording of the singing voice from each microphone is also started (S1). That is, the singing sound input simultaneously to each air conduction and bone conduction microphone from the start of performance is recorded (S2). Then, when the performance is finished, the recording of the singing sound is finished (S3), and the recorded data is classified into the air conduction recording data and the bone conduction recording data and recorded in the recording data recording section of the RAM (S4). . Next, when the user of the duet music has received the reproduction of the recording data (S5), it is determined from any microphone (for example, from which of the microphones M1 and M2) (S6), In the case of reception with the microphone M1 designated from the user who uses the microphone M1, the combination of each recording data is extracted mainly by the microphone M1 (S7), and in the case of reception with the microphone M2 designated, the microphone M2 is selected. The combination of each recording data is extracted mainly (S8). Here, the “combined extraction as the subject” means only the air conduction recording data that is the recording data of the microphone that is not the subject in addition to the air conduction recording data and the bone conduction recording data that are the recording data of the subject microphone. Say to extract in combination. Then, the recording data extracted in combination and the performance data linked to the recording data are synchronously reproduced (S9).

As described above, according to the singing sound recording / playback system of the present invention, when a predetermined music is sung, the singing sound simultaneously input from the air conduction microphone and the bone conduction microphone is converted into the air conduction recording data and the bone conduction. By classifying the recording data into recording data and recording each recording data, it is possible to extract and record synchronously the user's air recording data and bone conduction data. Therefore, since the user can listen to the recorded singing sound as a synthesized sound of air conduction and bone conduction, the user can listen to it with the same atmosphere and impression as the actual singing sound.
