  However, in the conventional technology, the model vocal sound is emitted from the speaker provided in the karaoke performance device in the same manner as the user's singing sound, so the model vocal sound is heard outside and is heard by the user. May be embarrassed. In addition, the model vocal sound is usually emitted from one of the two left and right speakers, so the accompaniment music that should have been heard in the stereo system is normally produced in monaural only from the other speaker, which adversely affects the original karaoke system function. End up. There are models that emit model vocal sounds from both speakers, but this makes the model vocal sounds and singing sounds confusing, especially the distance between users and display devices, speakers, such as sightseeing buses and sightseeing boats. In the case of a certain karaoke performance apparatus or the like, even if it is relatively difficult to see the lyrics telop and it is desired to rely on the model vocal sound, it is not preferable because the model vocal sound and the singing sound are confused.

  In response to such a problem, for example, an exemplary vocal sound is emitted from a dedicated head-mounted (headphone-type) sound pressure type speaker and used by the user, so that the exemplary vocal sound is externally generated. Although a method of preventing the sound from being heard is conceivable, it is not preferable that the user wears a headphone that closes the user's ear because it becomes difficult for the user to hear his / her own singing sound emitted from the speaker included in the karaoke performance device.

  The present invention has been conceived in order to solve such inconveniences and problems. In a karaoke performance device having a user singing assist function, the user sings his / her singing voice from a speaker included in the karaoke performance device. It is an object to make it clear so that the model vocal voice and the singing voice are not confused, and the model vocal voice is not heard outside so that others cannot hear the model vocal voice.

  In order to solve such a problem, the inventors have found that the above-mentioned problem can be solved by transmitting an exemplary vocal voice to the user by means of bone conduction means, and have come up with the karaoke performance apparatus of the present invention.

  That is, the karaoke performance device according to claim 1 of the present invention has a bone transmission means for transmitting a model vocal sound for assisting singing to the user in a karaoke performance device having a user singing assist function. It is characterized by becoming.

  The karaoke performance apparatus according to claim 4 of the present invention is characterized in that, in the karaoke performance apparatus according to any one of claims 1 to 3, the bone conduction means is a head-mounted type of a user.

  According to the karaoke performance device of claim 1 of the present invention, the exemplary vocal sound for assisting the singing is transmitted as a bone conduction sound to the periphery of the user's ear, so that the exemplary vocal sound can be heard clearly. However, the user's ear is not closed, and the user can hear his / her singing voice clearly from the speaker provided in the karaoke performance device. Further, since the bone conduction means is in close contact with the periphery of the user's ear when in use, there is an effect that it is not possible to hear the model vocal sound outside and the other person does not hear the model vocal sound.

  Next, according to the karaoke performance device according to claim 2 of the present invention, since the bone conduction means is attached to the remote control device, the bone conduction means can be easily carried along with the remote control device. Convenience increases. Further, according to the karaoke performance apparatus of the third aspect of the present invention, since the bone conduction means is attached to the microphone device, it can be carried easily as in the case of the remote control device, and the user can hold the microphone device. In order to sing, the bone conduction means used during the singing and the microphone device can be handled integrally, which is convenient for handling both devices.

  Furthermore, according to the karaoke performance apparatus according to claim 5 of the present invention, since the bone conduction means is a user's head-mounted type, the user does not need to hold the bone transmission means in his / her hand. Even with a microphone device, you can sing as usual. Furthermore, if the microphone device is also integrated with the same head-mounted bone conduction means as the head-mounted type (headphone microphone mode), both hands can be freely used, particularly in vehicles such as private cars and commercial vehicles, You can also enjoy karaoke while driving without having to see the lyrics telop.

This karaoke music data with an exemplary vocal includes, for example, accompaniment music generation data such as MIDI data, lyric rendering data that is the origin of the generation of karaoke lyrics images, and recording data of an exemplary vocal voice sung along with the karaoke accompaniment music It consists of and.

  Here, the recording data of the model vocal voice is generally the data recorded by the voice of the singing along with the progress of the accompaniment music by the original song artists and song teachers, and the accompaniment music of the karaoke music data Is stored in a separate channel from the generated data. Here, the separate channel means that the recorded data is stored in a data format independent of the accompaniment music generation data and can be processed separately. In addition, the karaoke music data may be added with index information in which information related to the original song artist is recorded, or recording data such as a back chorus.

  The user requests a song he / she wants to sing through the remote control device (R) or the operation panel (5). The request song ID input from the remote control device (R) or the operation panel (5) is sent from the remote control device (R) via the remote control receiver (4) or directly from the operation panel (5). It is input to (6) and transmitted to the central control unit (2). The central control unit (2) is a system composed of a CPU, RAM, ROM and the like, and is connected to an operation input interface, a data storage unit (3), a synthesizer (7), a video control unit (10), and the like. ing. The music ID output from the operation input interface (6) is transmitted to the central control unit (2). The central control unit (2) stores the music ID received from the operation input interface (6) in an appropriate storage unit such as a RAM.

  The central control unit (2) sequentially selects the song IDs stored in the data storage unit (3) in descending order of priority, and sequentially selects karaoke music data corresponding to each song ID from the data storage unit (3). Acquire and perform sequentially. In this performance processing, the central control unit (2) drives the synthesizer (7) based on the accompaniment music generation data in the karaoke music data to generate karaoke accompaniment music and outputs it to the mixing amplifier (8). In addition, the central control unit (2) reproduces the recorded data of the exemplary vocal sound in the ADPCM decoder (12) and outputs the exemplary vocal sound to the gain controller (14) in real time. The gain controller (14) adjusts the audio signal from the ADPCM decoder (12) to the set gain instructed from the central control unit (2), and outputs the adjusted exemplary vocal audio signal to the mixing amplifier (8).

  The mixing amplifier (8) mixes the accompaniment music signal from the synthesizer (7) and the user voice signal from the microphone device (M), amplifies the mixed signal to a volume set by the user, and then the speaker. 20 and an exemplary vocal voice signal from the gain controller (14) is output to the bone transmission means (B). The central control unit (2) generates a lyric image synchronized with the accompaniment music based on the lyric rendering data attached to the karaoke music data, and the video control unit (10) synthesizes a background image on the background of the lyric image. After that, the video is output toward the display (D).

The volume detector (11) is a circuit for processing a user voice signal from the microphone device (M) and detecting the volume. The sound volume detector (11) samples and converts the audio signal from the microphone device (M) at an appropriate interval. The sample value of the volume detection unit (11) is sequentially taken into the central control unit (2) as user voice strength information corresponding to the strength level of the user voice.

  The level detection unit (13) is a circuit for processing the exemplary vocal audio signal output from the ADPCM decoder (12) to detect the exemplary vocal audio level. The level detection unit (13) samples and converts the audio signal from the ADPCM decoder (12) by sampling at an appropriate interval in the same manner as the volume detection unit (11). The sampling result of the level detection unit (13) is sequentially taken into the central control unit (2) as model vocal strength information corresponding to the model vocal strength change.

  The central control unit (2) sequentially compares the user voice strength information acquired from the volume detection unit (11) and the exemplary vocal voice strength information acquired from the level detection unit (13). In this comparison, the central control unit (2) considers sampling timings of the sound volume detection unit (11) and the level detection unit (13) and matches conditions such as temporal conditions and relative conditions. Here, there may be a slight sampling timing difference between the user voice strength information from the volume detector (11) and the exemplary vocal strength information from the level detector (13). By this comparison, the central control unit (2) calculates the strength difference of the user voice with respect to the model vocal.

  When the central control unit (2) determines that the strength difference obtained by this calculation indicates that the user voice has reached the model vocal voice based on a predetermined comparison criterion, the central control unit (2) Determines that the user is singing along with the progress of the accompaniment music, and sends an instruction to the gain controller (14) so that the gain setting value of the gain controller (14) becomes zero or the minimum state. . Here, the predetermined comparison standard is a standard for checking whether the volume of the user voice has sufficiently reached the standard volume of the model vocal, and whether or not the user should hear the model vocal voice. It is a standard to be established. The comparison reference includes a measurement error range of the sound volume detection unit (11), a detection error range of the level detection unit (13), and the like.

As a result, a model vocal voice is output from the bone transmission means (B). Moreover, if the user voice is farther away from the volume of the model vocal voice, the voice output level of the model vocal voice is increased as the model vocal voice is farther away.

  The central control unit (2) sequentially performs the above comparison during the performance process of the singing part of the karaoke data, and adjusts the gain setting value of the gain controller (14) in real time based on the strength difference calculated thereby. The central control unit (2) maintains the gain setting value as it is between comparisons. Therefore, when the user cannot understand the melody while he is singing and cannot follow the accompaniment music, the model vocal will be sounded at just the right volume until the accompaniment music can be followed again. Become. For this reason, even if the user cannot go along with the accompaniment music while singing, the user can start singing again from the middle of the accompaniment music by listening to the model vocal voice output from the bone transmission means (B). it can. The central control unit (2) ends the vocal assist for one requested song, and when performing the performance process for the next requested song, sets the gain setting value of the gain controller (14) to zero or a minimum near zero. Set to the value of.

  Note that the present invention is not limited to the present embodiment. For example, exemplary vocal strength information corresponding to a change in strength of exemplary vocal sound is acquired based on the strength information of the main melody part sound included in the accompaniment music generation data of karaoke data. May be. Specifically, when the accompaniment music generation data is MIDI format data, the exemplary vocal voice strength information is acquired based on the velocity information (sound strength information) of the main melody part included in the MIDI data.
