Description

[Technical Field]

[0001] The present invention relates to a karaoke system. [Background technology]

[0002] In karaoke establishments such as karaoke booths, various management operations are performed using a management device installed at the front desk or elsewhere. The management device, for example, manages the usage time of each karaoke machine installed in each room of the karaoke establishment. Based on the usage time managed by the management device, employees of the karaoke establishment will notify users that their usage time is about to end and inquire about whether or not they would like to extend it. Room users will need to respond verbally to such notifications and inquiries.

[0003] Therefore, for example, Patent Document 1 discloses a karaoke system in which the front desk terminal sends end notification information to the karaoke terminal five minutes before the end, and if no response is received from the karaoke terminal and the end time has passed, it performs end processing, while if a response is received from the karaoke terminal and that response is an extension instruction, it sends information for selecting an extension time, and if there is a response to that, it updates the end time in the management table according to the response.

[0009] [Figure 1] 1 is a diagram showing a karaoke system according to an embodiment; [Figure 2] FIG. 1 illustrates a management device according to an embodiment. [Figure 3] 1 is a diagram showing a karaoke device according to an embodiment; [Figure 4] 1 is a diagram showing a karaoke machine main body according to an embodiment; [Figure 5] 3 is a flowchart showing the processing of the karaoke system according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] <Embodiment> A karaoke system according to an embodiment will be described with reference to FIGS.

[0011] ==Karaoke System== The karaoke system includes a management device and karaoke devices. The management device and the karaoke devices are connected to each other so that they can communicate with each other. As shown in Fig. 1, the karaoke system 1 according to this embodiment includes a management device F and karaoke devices K1 to K3.

[0012] The management device F is a computer installed in the karaoke store S. The management device F performs various management tasks at the karaoke store S, such as managing the usage time of the karaoke machines installed in each room. The employee W performs front desk duties at the karaoke store S.

[0013] Karaoke machines K1 to K3 are machines for performing karaoke and for users to sing karaoke. As shown in FIG. 1, in this embodiment, karaoke machine K1 is installed in room R1, karaoke machine K2 is installed in room R2, and karaoke machine K3 is installed in room R3. The management device F and each karaoke machine can communicate with each other via a network within the karaoke store S, such as a LAN. Users U1 to U3 are users of karaoke machine K1. Although FIG. 1 shows an example in which there are three karaoke machines, there only needs to be at least one karaoke machine.

[0014] Each room is equipped with a lighting device and a sound collection device. The lighting device is a light for adjusting the brightness of the room. The sound collection device is a microphone for collecting sounds in the room, such as the voices of users. As shown in FIG. 1, in this embodiment, a lighting device IL1 and a sound collection device SC1 are installed in room R1, a lighting device IL2 and a sound collection device SC2 are installed in room R2, and a lighting device IL3 and a sound collection device SC3 are installed in room R3.

[0015] ==Management device== The configuration of the management device F will be described with reference to Fig. 2. As shown in Fig. 2, the management device F includes a storage means 10, a communication means 11, a display means 12, an input means 13, and a control means 14. Each component is connected to the bus B via an interface (not shown).

[0016] [Memory means, communication means, display means, input means] The storage means 10 is a large-capacity storage device that stores various types of data. In this embodiment, the storage means 10 associates device identification information with usage time and stores it as reservation information. The device identification information is information specific to the karaoke device installed in each room, such as an ID assigned to each karaoke device. The usage time is the time during which a user can use the karaoke device. The usage time can be set according to the user's request. Note that typically, one karaoke device is installed in each room. In other words, since there is a one-to-one correspondence between karaoke devices and rooms, the usage time of the karaoke device is equal to the usage time of the room.

[0017] The communication means 11 provides an interface for communicating with each karaoke device. The display means 12 is a display that displays various information. The input means 13 is configured to allow the staff to input various instructions. If the display means 12 is configured in a touch panel format, the display means 12 may function as the input means 13.

[0018] For example, suppose a customer visiting a karaoke store requests "two hours" as the time they wish to use a karaoke machine. In this case, the employee uses the input means 13 to specify a karaoke machine that is not currently in use and inputs the usage time as "two hours." The storage means 10 associates the device identification information of the specified karaoke machine with the input usage time, and stores the information as reservation information.

[0019] [Control means] The control means 14 performs various controls in the management device F. The control means 14 includes a CPU and a memory (neither of which is shown). The CPU executes programs stored in the memory to realize various functions.

[0020] In this embodiment, the control means 14 functions as a notification unit 100 and an extension processing unit 200 .

[0021] (Notification Department) The notification unit 100 transmits usage end information to a karaoke device whose usage time is nearing the end.

[0022] The usage end information is information that notifies a karaoke machine that the usage time requested in advance is about to end. The usage end information includes extension possibility information. The extension possibility information is information that indicates whether the usage time of a karaoke machine can be extended. The extension possibility information is created according to the reservation status of a karaoke machine (described below).

[0023] The notification unit 100 monitors the usage time included in the reservation information stored in the storage means 10. When the remaining usage time satisfies a predetermined condition, the notification unit 100 generates usage end information to be sent to the karaoke device corresponding to the device identification information linked to the usage time. The predetermined condition is set in advance, for example, "5 minutes or less" or "3 minutes or less."

[0024] In addition, at the time when the usage end information is generated, the notification unit 100 checks whether other reservation information containing the same device identification information as the device identification information linked to the detected usage time is stored in the storage means 10.

[0025] If no other reservation information is stored, or if the usage time included in the other reservation information is later than the extension time, the notification unit 100 creates extension possibility information indicating that the usage time can be extended and includes it in the usage end information. The extension time is set in advance, for example, to "one hour from the current time."

[0026] On the other hand, if other reservation information is stored and the usage time included in the other reservation information overlaps with the preset extension time, the notification unit 100 creates extension possibility information indicating that the usage time cannot be extended and includes it in the usage end information.

[0027] As a specific example, assume that the available extension time is "1 hour from the current time," the detected usage time is "18:00-20:00," and the current time is "19:55."

[0028] Here, if the usage time included in the other reservation information is "22:00-24:00", the usage time included in the other reservation information is later than the extension possible time (one hour from the current time, i.e., 19:55-20:55). Therefore, the notification unit 100 creates extension possible information indicating that the usage time can be extended, and includes it in the usage time.

[0029] On the other hand, if the usage time included in the other reservation information is "20:30-22:30," the usage time included in the other reservation information overlaps with the extension-allowed time (19:55-20:55). Therefore, the notification unit 100 creates extension availability information indicating that the usage time cannot be extended, and includes this information in the usage time.

[0030] The notification unit 100 transmits usage end information including extension availability information to the karaoke device corresponding to the device identification information.

[0031] (extension processing part) When the extension processing unit 200 receives extension application information from a karaoke machine that has transmitted usage end information including extension availability information indicating that the usage time can be extended, the extension processing unit 200 extends the usage time of the karaoke machine.

[0032] The extension request information is information indicating a request to extend the usage time.

[0033] When the extension processing unit 200 receives extension application information from a karaoke machine, it extends the usage time associated with the device identification information of the karaoke machine stored in the storage means 10. The extension time is set in advance, for example, to "30 minutes."

[0034] ==Karaoke Equipment== A karaoke machine is a device for playing karaoke music and for users to sing karaoke. Since the karaoke machines K1 to K3 shown in Fig. 1 all have the same configuration, the following description will be given taking the karaoke machine K1 as an example.

[0035] As shown in FIG. 3, the karaoke device K1 includes a karaoke main unit 20, a speaker 30, a display device 40, a microphone 50, and a remote control device 60.

[0036] The karaoke machine main unit 20 performs various controls related to karaoke performance and singing, such as controlling the performance of selected songs, controlling the display of lyrics and background images, and processing audio signals input through the microphone 50. The speaker 30 is configured to emit sound based on signals from the karaoke machine main unit 20. The speaker 30 is an example of "sound emitting means." The display device 40 is configured to display videos and images on a screen based on signals from the karaoke machine main unit 20. The microphone 50 is configured to convert the singing voice of the user singing karaoke into an analog audio signal and input it to the karaoke machine main unit 20. The remote control device 60 is a device for performing various operations on the karaoke machine main unit 20.

[0037] 4, the karaoke main unit 20 comprises a storage means 20a, a communication means 20b, an input means 20c, a performance means 20d, and a control means 20e. Each component is connected to a bus B via an interface (not shown).

[0038] [Memory means, communication means, input means, performance means] The storage means 20a is a large-capacity storage device that stores various data, such as accompaniment data for karaoke performance.

[0039] The communication means 20b provides an interface for communication with the remote control device 60, the management device F, the lighting device IL1, and the sound collection device SC1. The input means 20c is configured to allow the user to input various instructions. The input means 20c is a button or the like provided on the karaoke main unit 20. Alternatively, the remote control device 60 may function as the input means 20c.

[0040] Based on the control of the control means 20e, the performance means 20d performs karaoke performance of the music piece and processes signals based on the singing voice input through the microphone 50. The performance means 20d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[0041] [Control means] The control means 20e performs various controls on the karaoke device K1. The control means 20e includes a CPU and a memory (neither of which are shown). The CPU executes programs stored in the memory to realize various functions.

[0042] In this embodiment, the control means 20e functions as a notification unit 300, a determination unit 400, and an extension request unit 500 by the CPU executing a program stored in the memory.

[0043] (Notification Department) When the notification unit 300 receives the usage end information, it notifies the user of the karaoke machine that the usage time is about to end.

[0044] The notification can be made in various ways. For example, the notification unit 300 can notify the user of the karaoke machine that the usage time is about to end by controlling the performance means 20d so that the volume of the sound emitted from the sound emitting means gradually decreases.

[0045] Specifically, when the usage time of the karaoke machine K1 is nearing the end, the karaoke machine K1 receives usage end information from the management device F. When the usage end information is received, the notification unit 300 controls the performance means 20d so that the volume of the sound emitted from the speaker 30 (such as the singing voice of the karaoke singer, the karaoke performance sound, or the sound of commercials played between songs) gradually decreases. The user can recognize that the usage time is nearing the end by the volume of the sound being emitted.

[0046] Alternatively, the notification unit 300 may issue a notification by controlling a lighting device. For example, if the received usage end information includes extension possibility information indicating that the usage time can be extended and no karaoke performance is being performed on the karaoke device, the notification unit 300 can control a lighting device to gradually darken the room in which the karaoke device is installed.

[0047] Specifically, suppose that the usage end information received from the management device F includes extension availability information indicating that the usage time can be extended. In this case, the notification unit 300 checks whether a karaoke performance is being performed on the karaoke device K1. Generally, when a karaoke performance is being performed, the room is darkened to enhance the atmosphere. Conversely, when a karaoke performance is not being performed, the room is brightened to make it easier to search for songs, etc.

[0048] When karaoke performance is not being performed on the karaoke device K1 (i.e., when the room is bright), the notification unit 300 controls the lighting device IL1 to gradually darken the room R1 in which the karaoke device K1 is installed. By the room becoming dark even when no karaoke performance is being performed, the user can understand that the usage time is nearing the end but that the usage time can be extended.

[0049] Furthermore, if the received usage end information includes extension possibility information indicating that the usage time cannot be extended and karaoke performance is being performed on the karaoke device, the notification unit 300 can control the lighting device to gradually brighten the room in which the karaoke device is installed.

[0050] Specifically, if the received usage end information includes extension availability information indicating that the usage time cannot be extended, the notification unit 300 checks whether a karaoke performance is being performed on the karaoke device K1.

[0051] When a karaoke performance is being performed on the karaoke device K1 (i.e., when the lighting in the room is dim), the notification unit 300 controls the lighting device IL1 to gradually brighten the room R1 in which the karaoke device K1 is installed. By the room becoming brighter even though a karaoke performance is being performed, the user can understand that the usage time is nearing the end and that the usage time cannot be extended.

[0052] Alternatively, the notification unit 300 may notify by displaying a message on the display screen of the display device 40 or the remote control device 60. The messages to be used when the usage time can be extended and when the usage time cannot be extended are set in advance.

[0053] For example, if the received usage end information includes extension possibility information indicating that the usage time can be extended, the notification unit 300 causes the display device 40 to display a message informing the user that the usage time is about to end and that it can be extended.

[0054] Specifically, suppose the received usage end information includes extension availability information indicating that the usage time can be extended. In this case, the notification unit 300 displays a message on the display device 40 such as, "The usage time is about to end. You can extend it now. If you wish to extend it, please call for an encore!". The message allows the user to understand that the usage time is about to end, but that the usage time can be extended.

[0055] Furthermore, if the received usage end information includes extension availability information indicating that the usage time cannot be extended, the notification unit 300 causes the display device 40 to display a message informing the user that the usage time has ended.

[0056] Specifically, suppose the received usage end information includes extension availability information indicating that the usage time cannot be extended. In this case, the notification unit 300 displays a message on the display device 40 such as, "The usage time is about to end. The next reservation has been made, so please prepare to leave immediately." The message allows the user to understand that the usage time is about to end and that the usage time cannot be extended.

[0057] The notification unit 300 can also perform a combination of the above-mentioned control of the performance means 20d, control of the lighting device IL1, and display of a message. In this case, the user can more reliably know when the usage time has ended and whether it can be extended.

[0058] (Judgment Department) If the received usage end information includes extension possibility information indicating that the usage time can be extended, the determination unit 400 determines whether the voice input via the sound collection means includes a predetermined word.

[0059] The predetermined words are words that a user may utter when requesting an extension of the usage time, such as "encore" or "extension requested." At least one predetermined word is set in advance. The sound collection means collects sounds within the room. As the sound collection means, a sound collection device installed within the room or a microphone provided in the karaoke machine may be used.

[0060] In this embodiment, when usage end information is received that includes extension possibility information indicating that the usage time can be extended, the determination unit 400 controls the sound collection device SC1 to collect sound within the room R1.

[0061] The determination unit 400 analyzes the voice input via the sound collection device SC1 within a predetermined period (for example, from the start of sound collection to the end of the usage time) using a known voice processing technique, and extracts words contained in the voice. The determination unit 400 compares the extracted words with predetermined words, and determines whether the extracted words include the predetermined words. The determination unit 400 outputs the determination result to the extension request unit 500.

[0062] (Extension Application Department) If the predetermined word is included, the extension request unit 500 transmits the extension request information to the management device.

[0063] If the input determination result indicates that the predetermined word is included, the extension request unit 500 generates extension request information, associates it with the device identification information, and transmits it to the management device F. In this case, the management device F performs a process to extend the usage time included in the reservation information for the karaoke device K1 stored in the storage means 10. Note that if there are multiple pieces of reservation information for the karaoke device K1, the management device F performs a process to extend the usage time for the reservation information that includes the current usage time (the time when the extension request information is received).

[0064] On the other hand, if the determination result indicates that the predetermined word is not included, the extension request unit 500 does not perform any special process. In this case, the management device F deletes the reservation information for the karaoke device K1 (reservation information whose usage time has expired) stored in the storage means 10 after the usage time has elapsed.

[0065] ==About the Karaoke System== Next, the processing in the karaoke system 1 according to this embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing the processing in the karaoke system 1. In this example, as shown in Fig. 1, it is assumed that three users U1 to U3 visit a karaoke establishment S and use a karaoke machine K1 installed in room R1. The storage means 10 of the management device F has previously stored the usage times requested by users U1 to U3 in association with the device identification information of the karaoke machine K1. It is assumed that no other karaoke machines in the karaoke establishment S are being used.

[0066] Users U1 to U3 who have entered room R start using the karaoke device K1 (start of use; step 10).

[0067] The notification section 100 of the management device F manages the usage time of the karaoke device K1 (management of usage time; step 11).

[0068] When the end of the usage time is approaching (Y in step 12), the notification unit 100 sends usage end information to the karaoke device K1, including extension possibility information indicating whether the usage time of the karaoke device K1 can be extended (send usage end information; step 13).

[0069] When the notification unit 300 of the karaoke device K1 receives the usage end information transmitted in step 13, it notifies the users U1 to U3 of the karaoke device K1 that the end of usage time is approaching (notifying that the end of usage time is approaching; step 14).

[0070] Here, if the received usage end information includes extension possibility information indicating that the usage time can be extended (Y in step 15), the judgment unit 400 judges whether the voice input via the sound collection device SC1 includes a predetermined word.

[0071] If the predetermined word is included (Y in step 16), the extension application unit 500 transmits the extension application information to the management device F (transmit extension application information; step 17).

[0072] When the extension application information is received from the karaoke device K1, the extension processing unit 500 of the management device F extends the usage time of the karaoke device K1 (extending the usage time of the karaoke device; step 18).

[0073] If the received usage end information includes extension permission information indicating that the usage time cannot be extended (N in step 15) or if the voice input via the sound collection device SC1 does not include a predetermined word (N in step 16), the karaoke device K1 does not generate extension request information. In this case, users U1 to U3 can sing karaoke up to the requested usage time.

[0074] As is clear from the above, the karaoke system 1 according to this embodiment includes a management device F and karaoke devices K1 to K3 connected to each other so that they can communicate with each other. The management device F includes a notification unit 100 that transmits usage end information to a karaoke device whose usage time is about to expire, the notification unit 100 including extension availability information indicating whether the usage time of the karaoke device can be extended, and an extension processing unit 200 that extends the usage time of the karaoke device when it receives extension request information from the karaoke device that transmitted the usage end information including the extension availability information indicating that the usage time can be extended. Each karaoke device includes a notification unit 300 that notifies the user of the karaoke device that the usage time is about to expire when it receives the usage end information. If the received usage end information includes the extension availability information indicating that the usage time can be extended, the notification unit 400 determines whether the voice input via the sound collection means contains a predetermined word. If the received usage end information contains the extension availability information indicating that the usage time can be extended, the determination unit 400 determines whether the voice input via the sound collection means contains a predetermined word. If the predetermined word is included, the determination unit 500 transmits extension request information to the management device F.

[0075] With this karaoke system 1, usage end information including extension availability information can be sent to karaoke machines when the usage time is about to expire. This saves karaoke store employees the trouble of contacting each room to inform them that the usage time is about to expire. Furthermore, since usage time can be extended by uttering a specific word, the atmosphere of the karaoke singing experience is not spoiled. In other words, with the karaoke system 1 according to this embodiment, it is easy to request an extension of usage time.

[0076] Furthermore, the notification unit 300 of the karaoke system 1 according to this embodiment can notify the user of the karaoke device that the end of the usage time is approaching by controlling the performance means 20d so that the volume of the sound emitted from the speaker 30 gradually decreases. In this way, the volume of the sound emitted from the speaker 30 automatically decreases, allowing the user to know that the end of the usage time is approaching.

[0077] Furthermore, when the received usage end information includes extension possibility information indicating that the usage time can be extended and no karaoke performance is being performed on the karaoke device, the notification unit 300 of the karaoke system 1 according to this embodiment can control the lighting device to gradually darken the room in which the karaoke device is installed. On the other hand, when the received usage end information includes extension possibility information indicating that the usage time cannot be extended and karaoke performance is being performed on the karaoke device, the notification unit 300 can control the lighting device to gradually brighten the room in which the karaoke device is installed. In this way, by controlling the lighting device and adjusting the brightness of the lighting in the room, the user can easily know that the usage time is nearing the end and whether the usage time can be extended.

[0078] <Variation 1> For example, when multiple people are using a karaoke machine, a certain word may be accidentally uttered during conversation even though no extension of the usage time is desired. Therefore, the determination unit 400 according to this modification can determine whether the voice input via the sound collection means contains a certain number of certain words. The extension request unit 400 according to this modification can transmit extension request information to the management device F only when the certain word is contained a certain number of times. The certain number is set in advance, for example, 10 times.

[0079] Specifically, similar to the embodiment, the determination unit 400 analyzes the voice input via the sound collection device within a predetermined period of time using a known voice processing technique, and extracts words contained in the voice.

[0080] The determination unit 400 compares the extracted words with predetermined words and determines whether the extracted words include a predetermined number of predetermined words or more. The determination unit 400 outputs the determination result to the extension request unit 500.

[0081] When the judgment result that the predetermined word is included a predetermined number of times or more is input, the extension request unit 500 generates extension request information and transmits it to the management device F. On the other hand, when the judgment result that the predetermined word is not included a predetermined number of times or more is input, the extension request unit 500 does not generate extension request information.

[0082] As described above, in the karaoke system 1 according to this modification, the determination unit 400 determines whether the voice input via the sound collection means contains a predetermined number of predetermined words or more. If the predetermined number of predetermined words or more is contained, the extension request unit 500 transmits extension request information to the management device F. With this karaoke system 1, it is possible to prevent the user from unintentionally extending the playing time.

[0083] <Variation 2> For karaoke stores, it is preferable to extend the usage time if there is no next reservation for the karaoke machine currently in use. Therefore, if the received usage end information includes extension possibility information indicating that the usage time can be extended, the notification unit 300 according to this modification can start playing content to encourage the user to extend the usage time after the sound emitted from the sound emitting means becomes silent.

[0084] The content is composed of video and audio to encourage users to extend their usage time. The video is, for example, a video of a dimly lit stage, such as an encore scene at a live concert. The audio is, for example, the applause, whistling, and cheers of the audience. Data corresponding to the content is stored in advance in storage means 20a.

[0085] As described in the embodiment, when usage end information is received, the notification unit 300 controls the performance means 20d so that the volume of the sound emitted from the speaker 30 gradually decreases. Here, if the received usage end information includes extension availability information indicating that the usage time can be extended, the notification unit 300 reads data corresponding to the content from the storage means 20a and starts playback after the sound emitted from the speaker 30 becomes silent. As the content is played, an image is displayed on the display screen of the display device 40 and sound is emitted from the speaker 30. The user can watch the content until the usage time expires.

[0086] In this way, in the karaoke system 1 according to this modification, when the received usage end information includes extension possibility information indicating that the usage time can be extended, the notification unit 300 can start playing content to encourage the user to extend the usage time after the sound emitted from the sound emitting means becomes silent. By using such content, the user can be encouraged to utter a predetermined word such as "encore," thereby increasing the possibility of extending the usage time.

[0087] <Other> The above-described embodiments are presented as examples and do not limit the scope of the invention. The above configurations can be implemented in appropriate combinations, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The above-described embodiments and their modifications are included in the scope and spirit of the invention, as well as in the inventions described in the claims and their equivalents.
