Description

  The present invention relates to a karaoke microphone for transferring a user's singing voice to a karaoke performance apparatus, and more particularly to a karaoke microphone with bone conduction means for transmitting predetermined singing assist information.

  Currently, a karaoke system has been developed that provides various singing assistance information to karaoke users and assists the singing of the users. For example, a karaoke performance device is usually accompanied by a function of emitting a guide melody that guides the singing so that the user does not remove the pitch. With this function, if you are singing a song that you are not used to singing or a song that is very difficult to sing, if you do not know how to sing while you are singing and you can not follow the accompaniment music, the main melody of the song is firmly It is preferable to increase the volume of the guide melody so that it can be heard because it is easier to sing. On the other hand, it is preferable that the volume of the guide melody is relatively small or not so that the singing sound can be heard professionally. Conventionally, various technologies have been developed to meet such demands. For example, Patent Document 1 discloses a karaoke performance device that can reproduce a guide melody by a user's operation. Further, Patent Document 2 discloses a karaoke performance device that analyzes a singing situation in real time and automatically emphasizes a guide melody when a main melody is sung.

In the same manner as described above, a karaoke performance device has been introduced in which an exemplary vocal sound is played when a user cannot go with accompaniment music. As a technique related to such a karaoke performance device, for example, Patent Document 3 discloses a mechanism for detecting the presence or absence of a singing input from a karaoke microphone and playing an exemplary vocal sound when there is no singing input. Further, in Patent Document 4, a karaoke performance in which an exemplary vocal sound is played at a volume that compensates for the shortage when the input volume from a karaoke microphone is measured and the input volume is smaller than the volume of accompaniment music. An apparatus is disclosed. In addition, a karaoke performance device is also conceived in which a guide melody or an exemplary vocal sound is played at a volume that is inversely proportional to the input volume from the karaoke microphone.

  However, in such a conventional technique, for example, the guide melody is always emitted from the speaker provided in the karaoke performance device in the same manner as the user's singing voice, so that the volume change of the guide melody is also transmitted to others. It may be uncomfortable for others. In addition, the model vocal sound is emitted from the speaker provided in the karaoke performance device in the same way as the user's singing sound, so the other person can hear the model vocal sound and is heard by the person and feels embarrassed by the user. There is. In addition, when the model vocal sound is emitted, the model vocal sound and the singing sound are mixed, and the model vocal sound and the singing sound are confusingly heard.

  For such problems, for example, singing assist information is emitted from a dedicated head-mounted (headphone-like) sound pressure type speaker and used by the user so that the other person can use the singing assist information. Although a method of preventing information from being heard is conceivable, it is preferable that a user wears headphones that block the user's ears, and this time it is difficult for the user to hear his / her own singing voice emitted from the speaker of the karaoke performance device. Absent.

  The present invention has been conceived to solve such inconveniences and problems, that is, for the user who is singing, the singing voice and singing assist information are not confused, It is an object to provide a karaoke system using the means capable of receiving singing assistance effectively so that it can be clearly heard and allowing only others to listen to the singing voice of the user. And

  In view of the above problems, the present inventor adopts a bone conduction technology, which is a technology for transmitting voice and music through a human bone, in a karaoke microphone, and suitably transmits singing assist information to the back of the user's hand holding this. I came up with a technology that could be done. That is, a bone conduction speaker and a karaoke microphone attached with a bone conduction speaker holding body that holds the bone conduction speaker so that the back of the user's hand and the bone conduction speaker come into contact with each other when the user grips the microphone body; Using this karaoke microphone, we found that the above problems can be solved by a karaoke system that can provide singing assistance information such as a guide melody and model vocal voice, and conceived of a karaoke microphone of the present invention and a karaoke system using the same. .

  That is, the karaoke microphone according to claim 1 of the present invention is a karaoke microphone for transferring a user's singing voice to a karaoke performance device, a bone conduction speaker for transmitting predetermined singing assist information, and a user Bone conduction means comprising a bone conduction speaker holding body for holding the bone conduction speaker so that the back of the user's hand and the bone conduction speaker come into contact with each other when the microphone body is gripped To do.

  Further, the karaoke microphone according to claim 2 of the present invention is the karaoke microphone according to claim 1, wherein the bone conduction speaker holder and the microphone body are joined, and can be expanded or contracted, and at the time of extension or deformation, Bone conduction means further comprising an elastic joint that acts so as to press the bone conduction speaker holding body toward the microphone main body is attached.

  Furthermore, the karaoke system according to claim 3 of the present invention is a karaoke system using the karaoke microphone according to claim 1 or 2, wherein the singing assist information is a guide melody or an example in a predetermined karaoke piece. It is vocal voice, The said song assistance information is transmitted to a user via the said bone conduction means, It is characterized by the above-mentioned.

  According to the karaoke microphone according to claim 1 of the present invention, the bone conduction speaker for transmitting predetermined singing assist information is configured to come into contact with the back of the user's hand when the user grasps the microphone body. Thus, the singing assist information can be suitably transmitted from the back of the user's hand, and the singing voice and the singing assist information are not confusing to the user who is singing, and each can be heard clearly, For other people, there is an effect that only the user's singing voice can be heard.

  Moreover, according to the karaoke microphone according to claim 2 of the present invention, when the user holds the karaoke microphone by the elastic joint body that acts to press the microphone main body side including the bone conduction speaker holding body, When the back of the hand and the bone conduction speaker are sufficiently brought into close contact with each other, the transmission efficiency is improved, and the singing assist information can be more suitably transmitted from the back of the user's hand.

  Further, according to the karaoke system according to claim 3 of the present invention, the guide melody and the exemplary vocal sound in the predetermined karaoke music are used by utilizing the bone conduction means of the karaoke microphone according to claim 1 or 2. Because it can be transmitted to the user, the singing voice and the singing assist information are not confusing to the user who is singing, and each can be heard clearly, so it can receive singing assistance effectively, On the other hand, there is an effect that only the user's singing voice can be heard.

  Hereinafter, preferred embodiments of the karaoke microphone according to the present invention will be given to describe the present invention in detail.

  FIG. 1 is an explanatory diagram of a configuration example (A) and a usage example (B) of a karaoke microphone in one embodiment of the present invention. First, as shown in (a), the karaoke microphone (1) in the present embodiment includes a sound collection cap (3), a microphone body (2), a power switch (4), a connection cable (5), and bone conduction. Means (6) is the main component. It should be noted that the bone conduction technique in the present invention may be a currently known technique, in which vibration waves such as voices and musical sounds are conducted through a human bone and information is transmitted to the brain. Information is transmitted as long as it is in contact with the user's own bones, but others cannot hear this information. Usually, information is transmitted through bones such as the skull and mandible, but recently the performance has improved to the point where information can be transmitted from the back of the hand.

  The bone conduction means (6) of the present embodiment includes a bone conduction speaker (6a) for transmitting predetermined singing assist information, and a user uses the microphone main body (2) as shown in the usage example (b). A bone conduction speaker holding body (6b) for holding the bone conduction speaker (6a) so that the back (H) of the user's hand and the bone conduction speaker (6a) come into contact with each other when gripped; and a bone conduction speaker The bone conduction speaker bone conduction speaker holding body (6b) and the microphone main body (2) are joined at one edge of the bone conduction speaker holding body (6b) and can be deformed. It consists of an elastic joined body (6c) that acts to press the holding body (6b) toward the microphone body (2), a connection cord (6d), and the like.

  In the present embodiment, the elastic joined body (6c) is a “U-shaped” leaf spring, and when the “U-shaped” spreads and deforms due to the thickness of the user's hand, naturally, at the time of deformation, The elastic joint body (6c) acts to press the bone conduction speaker bone conduction speaker holding body (6b) toward the microphone body (2), so that the back of the user's hand (H) sandwiched between the elastic conduction body (6c) and the bone conduction speaker. (6a) will be sufficiently in close contact with each other, and singing assist information can be suitably transmitted to the bone.

  Next, FIG. 2 is an explanatory diagram of a configuration example (A) and a usage example (B) of a karaoke microphone in another embodiment of the present invention. First, as shown in FIG. As in FIG. 1, the karaoke microphone (1) mainly includes a sound collection cap (3), a microphone body (2), a power switch (4), an information transmission cable (5), and a bone conduction means (6). It is a necessary configuration requirement.

  The bone conduction means (6) of the present embodiment includes a bone conduction speaker (6a) for transmitting predetermined singing assist information, and a user uses the microphone main body (2) as shown in the usage example (b). A bone conduction speaker holding body (6b) for holding the bone conduction speaker (6a) so that the back (H) of the user's hand and the bone conduction speaker (6a) come into contact with each other when gripped; and a bone conduction speaker The bone conduction speaker bone conduction speaker holding body (6b) and the microphone main body (2) are joined at both side edges of the bone conduction speaker holding body (6b), and can be expanded and contracted. It consists of an elastic joined body (6c) that acts to press the holding body (6b) toward the microphone body (2), a connection cord (6d), and the like.

  In this embodiment, the elastic bonded body (6c) is a coil-shaped spring. When the coil expands and expands due to the thickness of the user's hand, naturally, the elastic bonded body (6c) is bone-conducted during the expansion. Since the speaker bone conduction speaker holder (6b) acts to press the microphone body (2) side, the back (H) of the user's hand held between them and the bone conduction speaker (6a) are sufficiently adhered to each other. Therefore, the singing assist information can be suitably transmitted to the bone. The elastic joined body of the present invention is not limited to the springs such as the leaf spring and the coiled spring shown in the first and second embodiments, and may be, for example, a flexible resin having a shape restoring function. I do not care. In addition, although this elastic joined body is not necessarily required in the present invention, it also has an action of buffering the influence of vibration generated during bone conduction on the microphone body, thereby preventing adverse effects on the user's singing voice acquisition. Therefore, it is preferable to attach to the bone conduction means.

  Here, based on the block diagram of the karaoke microphone of the present invention shown in FIG. 3, the karaoke microphone of the present invention will be described in more detail.

  The karaoke microphone (1) of the present embodiment is a wired type, and a sound pressure receiving unit (9) that vibrates in response to the sound pressure of a singer's singing voice, which is a component of a conventional dynamic microphone, and the vibration is an electrical signal. Piezoelectric conversion / modulation means (10) that performs predetermined modulation processing by converting into singing information, and further, singing assist information (bone conduction information) for the user transmitted from the karaoke performance device via the connection cable is converted into bone conduction means ( 6) Bone conduction information interface (8) for acquiring input and central control for overall control such as overall control of these means and transfer control for transferring singing voice to a predetermined karaoke performance device Means (7) and the like. The present invention is not limited to the wired microphone shown in the present embodiment, and may of course be a wireless microphone having an infrared transmission function (or FM wave transmission function).

  Hereinafter, preferred embodiments of the karaoke system according to the present invention will be given to describe the present invention in detail.

First, FIG. 4 shows a block diagram of a karaoke system that provides a guide melody.
The karaoke system (S1) of the present embodiment has a karaoke performance device as a main component, and provides a user with a guide melody in predetermined karaoke music as singing assistance information. A hard disk device and a DVD-ROM drive device. And a data storage unit (13) composed of a CD-ROM drive device, etc., and in this data storage unit (13), singing assist information (guide melody data, etc.) corresponding to each song together with karaoke performance data for each song ) Is accumulated. The karaoke performance data includes, for example, accompaniment music generation data such as MIDI data, lyric rendering data that is the origin of karaoke lyrics image generation, and back chorus recording data sung along with karaoke accompaniment music. It is configured.

  When the user requests a song he / she wants to sing using the remote control device (11) or the operation panel (15), the ID code of the requested song input from the remote control device (11) or the operation panel (15) is the remote control device. From (11) via the remote control receiver (14) or directly from the operation panel (15) to the operation input interface (16) and transmitted to the central controller (12). The central control unit (12) is a system composed of a CPU, RAM, ROM and the like, including an operation input interface (16), a data storage unit (13), a synthesizer (17), a mixing amplifier (18), a video It is connected to the control unit (20) and the like. The music ID code input from the operation input interface (16) is transmitted to the central control unit (12), and the music ID code received from the operation input interface (16) according to the command of the central control unit (12) is stored in the RAM. Are stored in an appropriate storage unit.

  The central control unit (12) selects the song ID codes stored in the data storage unit (13) in descending order of priority, and selects the karaoke performance data corresponding to each song ID code from the data storage unit (13). ) And sequentially perform performance processing. In this performance process, the central control unit (12) drives the synthesizer (17) based on the accompaniment music generation data in the karaoke performance data to generate karaoke accompaniment music and outputs it to the mixing amplifier (18). The central control unit (12) reproduces the recorded data of the back chorus in the ADPCM decoder (22) and outputs it to the mixing amplifier (18) in real time.

  The mixing amplifier (18) mixes the accompaniment music signal from the synthesizer (17), the singing voice signal from the karaoke microphone (1), and the back chorus signal from the ADPCM decoder (22). After being amplified to the volume set by the user, it is output from the speaker (19). The central control unit (12) generates a lyric image synchronized with the accompaniment music based on the lyric rendering data attached to the karaoke performance data, and the video control unit (20) synthesizes the background video to the background of the lyric image. After that, the video is output to the display (D) and the guide melody signal from the gain controller (24) is output to the bone conduction means (6) of the karaoke microphone (1).

  The karaoke system (S1) of the present embodiment is provided with a volume detector (21). The volume detector (21) is a circuit for processing the singing voice signal from the karaoke microphone (1) and detecting the volume, and sampling the singing voice signal from the karaoke microphone (1) at an appropriate interval. And convert to digital. And the sample value of a sound volume detection part (21) is taken in one by one by the central control part (12) as singing voice strength information according to the strength level of singing voice.

  The central control unit (12) sequentially detects the singing voice strength information acquired from the volume detection unit (21). In this detection, the central control unit (12) considers the sampling timing of the sound volume detection unit (21). When the central control unit (12) confirms that the volume of the singing voice has reached a predetermined reference value and indicates that the pitch is not off by this detection, the central control unit (12) A guide melody is sent to the gain controller (24) so that the gain setting value of the gain controller (24) becomes zero or the minimum state, judging that the singing is properly performed in accordance with the progress of the accompaniment music. Is in a state that is hardly emitted. Here, the predetermined reference value is a reference for checking whether or not the volume of the singing voice has sufficiently reached the standard volume, and is a reference that determines whether or not the user should hear the guide melody. . In the present embodiment, in order to ensure the reliability of the singing guidance, the volume detector (21) also takes into account the degree of off-pitch, but this detection is difficult and complicated processing using a predetermined algorithm. It is not always necessary because judgment is forced.

  On the other hand, when the central control unit (12) confirms that the singing voice is lower than the standard volume at the predetermined reference value, the central control unit (12) has a large lower difference. The gain controller (24) is adjusted so as to increase the gain. Thereby, a guide melody is output from the bone conduction speaker of the bone conduction means (6). In addition, if the singing voice is far from the standard volume, the guide melody having a larger volume is output as the sound output level of the guide melody is farther away. Further, in addition to this, a guide melody having a louder volume is output as the pitch is larger in terms of pitch.

  The central control unit (12) sequentially performs the above detection during the performance processing of the singing part of the karaoke performance data, thereby adjusting the gain setting value of the gain controller (24) in real time. The central control unit (12) maintains the gain setting value as it is between detections. Therefore, when the user cannot understand the melody during singing and can not follow the accompaniment music, the guide melody will be output from the bone conduction speaker at the right volume until the accompaniment music can be followed again. Will be.

  For this reason, even if the user can not follow the accompaniment music while singing, the user can start to sing again from the middle of the accompaniment music by listening to the guide melody output from the bone conduction means (6). . When the central control unit (12) finishes one requested song and performs the performance processing for the next requested song, the gain controller (24) sets the gain setting value of the gain controller (24) to zero or a minimum value close to zero. Set.

  Next, FIG. 5 shows a block diagram of a karaoke system that provides an exemplary vocal voice. The karaoke system (S2) of the present embodiment has a karaoke performance device as a main component, and provides model vocal sounds in predetermined karaoke music to the user as singing assist information. The basic configuration requirements are a central control unit (12), a data storage unit (13), a remote control device (11), a remote control receiving unit (14), an operation panel (15), an operation input interface (16), The description of the synthesizer (17), the mixing amplifier (18), the speaker (19), the video control unit (20), the volume detection unit (21), the display (D), and the like is the same as that of the third embodiment.

  The karaoke system (S2) of the present embodiment includes a level detection unit (23) together with a volume detection unit (21). The level detection unit (23) is a circuit for processing the exemplary vocal audio signal output from the ADPCM decoder (22) to detect the audio level of the exemplary vocal audio. The level detection unit (23) is an ADPCM. The audio signal from the decoder (22) is sampled at an appropriate interval and digitally converted in the same manner as the sound volume detector (21). The sampling result of the level detection unit (23) is sequentially taken into the central control unit (12) as model vocal voice strength information corresponding to the strength change of the model vocal voice.

  The central control unit (12) sequentially compares the singing voice strength information acquired from the volume detection unit (21) and the exemplary vocal voice strength information acquired from the level detection unit (23). In this comparison, the central control unit (12) considers sampling timings of the sound volume detection unit (21) and the level detection unit (23), and matches conditions such as temporal conditions and relative conditions. Here, there may be a slight sampling timing difference between the singing voice strength information from the volume detection section (21) and the exemplary vocal voice strength information from the level detection section (23). By this comparison, the central control unit (12) calculates the strength difference between the singing voice and the model vocal voice.

  When the central control unit (12) confirms that the strength difference obtained by this calculation indicates that the singing voice has reached the model vocal voice based on a predetermined comparison criterion, the central control unit (12) It is determined that the user is singing along with the progress of the accompaniment music, and an instruction is sent to the gain controller (24) so that the gain setting value of the gain controller (24) becomes zero or minimum. Here, the predetermined comparison standard is a standard for examining whether or not the volume of the singing voice has sufficiently reached the standard volume, and is a standard for determining whether or not the model vocal voice should be heard by the user. . The comparison reference includes a measurement error range of the sound volume detection unit (21), a detection error range of the level detection unit (23), and the like.

  On the other hand, when the central control unit (12) confirms that the strength difference obtained by the calculation indicates that the singing voice is lower than the exemplary vocal voice based on a predetermined comparison criterion, the central control unit (12 ) Adjusts the gain controller (24) so that the gain becomes larger as the lower difference becomes larger. Thereby, an exemplary vocal sound is output from the bone conduction speaker of the bone conduction means (6). Moreover, if the singing voice is farther away from the volume of the exemplary vocal sound, the higher the distance is, the higher the exemplary vocal sound is.

  The central control unit (12) sequentially performs the above comparison during the performance processing of the singing part of the karaoke performance data, and adjusts the gain setting value of the gain controller (24) in real time based on the strength difference thus calculated. . The central control unit (12) maintains the gain setting value as it is between comparisons. Therefore, when the user is unable to understand the melody while singing and cannot follow the accompaniment music, the model vocal sound is heard from the bone conduction speaker at a good volume until the accompaniment music can be followed again. Will be output. For this reason, even if the user can not follow the accompaniment music while singing, the user can start singing again from the middle of the accompaniment music by listening to the model vocal sound output from the bone conduction means (6). it can.

  As described above in detail, according to the karaoke microphone of the present invention and the karaoke system using the karaoke microphone, the bone conduction technique, which is a technique for transmitting voice and music through a human bone, is adopted in the karaoke microphone. Singing assist information can be suitably transmitted to the back of the user's hand, so the singing voice and singing assist information are not confusing to the user who is singing, and each can be heard clearly, Singing assistance can be effectively received, and only the user's singing voice can be heard from others.
