DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] <Embodiment> A karaoke device according to an embodiment will be described with reference to FIGS. 1 to 4.

[0011] ==Karaoke Equipment== A karaoke device is a device for playing karaoke songs and allowing users to sing karaoke. The karaoke device is installed in a karaoke room of a karaoke store. The karaoke device is connected so as to be able to communicate with a store terminal installed in the karaoke store and a server device installed outside the karaoke store (neither of which are shown in the figure). The store terminal stores reservation information for the karaoke rooms. The reservation information is information relating to reservations for each karaoke room, such as the reservation status (start time and end time of use of the karaoke room, number of users, etc.).

[0012] 1, a karaoke device K is installed in a karaoke room R. The karaoke device K is used by a user U. The karaoke device K includes a karaoke main unit 10, a speaker 20, a display device 30, a microphone 40, and a remote control device 50.

[0013] The karaoke main unit 10 performs various controls related to karaoke performance and singing, such as karaoke performance control of the selected song, display control of lyrics and background images, and processing of audio signals input through the microphone 40. The speaker 20 is configured to emit sound based on a sound emission signal from the karaoke main unit 10. The speaker 20 is an example of "sound emission means." The display device 30 is configured to display videos and images on a screen based on a signal from the karaoke main unit 10. The microphone 40 is configured to convert the voice uttered by the user into an analog audio signal and input it to the karaoke main unit 10. The remote control device 50 has a display screen and is a device for performing various operations on the karaoke main unit 10. The display device 30 and / or the remote control device 50 are examples of "display means."

[0014] 2, the karaoke machine 10 according to this embodiment includes a storage means 10a, a communication means 10b, an input means 10c, a performance means 10d, and a control means 10e. Each of these components is connected to a bus B via an interface (not shown).

[0015] [Storage means] The storage means 10a is a large-capacity storage device that stores various types of data. The storage means 10a stores music data.

[0016] The song data is provided with song identification information for identifying each song. The song identification information is information unique to each song, such as a song ID for identifying the song. The song data includes accompaniment data, reference data, etc. The accompaniment data is data that is the source of the karaoke performance sound. The reference data is data that indicates the singing melody of the song performed as karaoke, and is used when evaluating the karaoke singing by a user.

[0017] The storage means 10a stores lyric subtitle data for displaying lyrics corresponding to each piece of music on the display device 30 or the like in sync with the karaoke performance, background image data such as background images to be displayed on the display device 30 or the like during the karaoke performance, and attribute information of the music (song title, singer name, genre, performance time, etc.).

[0018] [Communication means / input means] The communication means 10b provides an interface for communicating with the remote control device 50. The input means 10c is configured to allow the user to input various operations. The input means 10c is a button or the like provided on the karaoke main unit 10. Alternatively, the remote control device 50 may function as the input means 10c.

[0019] [Means of performance] Based on the control of the control means 10e, the performance means 10d performs karaoke performance of music pieces and processes audio signals input through the microphone 40. The performance means 10d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[0020] [Control Means] The control means 10e performs various controls in the karaoke device K. The control means 10e includes a CPU and a memory (neither of which are shown in the figures). The CPU realizes various functions by executing programs stored in the memory.

[0021] In this embodiment, the control means 10e functions as a generation unit 100, a confirmation unit 200, a calculation unit 300, and an encore processing unit 400 by the CPU executing a program stored in the memory.

[0022] (Generation part) The generating unit 100 generates a list of songs that the user has sung karaoke from the user's singing history.

[0023] The singing history of a user includes song information (song title, performance time, genre, artist name, etc.) about the song that the user has sung karaoke, the date and time when the song was sung karaoke, the scoring results, etc. The singing history is stored in a storage means such as a server device in association with user identification information. The user identification information is information unique to each user, such as a user ID for identifying the user.

[0024] In response to a user's login, the karaoke device K obtains the user's singing history from the server device. A known method can be used to log in to the karaoke device K. A user who wishes to log in operates the remote control device 50 to input his / her own user identification information and a preset password. The karaoke device K transmits a login request including the input user ID and password to the server device. The server device reads out the singing history associated with the user identification information included in the received login request from the storage means and transmits it to the karaoke device K. The karaoke device K that transmitted the login request completes the login to the karaoke device K by storing the received singing history in the storage means 10a.

[0025] The generating unit 100 references the song information included in the received singing history and generates a list of songs. The list of songs is a list of some or all of the songs that the user has sung karaoke. The list of songs may be randomly organized, or may be organized in order of the longest or shortest playing time of the songs.

[0026] 3 is an example of a song list L generated from the singing history of a user U. The song list L includes song titles (songs X1 to Xn), song IDs, and performance times. The song list L is also organized in descending order of longest performance time.

[0027] (Verification Department) When the karaoke performance of one piece of music is finished, the confirmation unit 200 confirms whether the karaoke performance of another piece of music is reserved or not.

[0028] After completing the login to the karaoke device K, the user operates the remote control device 50 to select a song that the user wants to sing. The karaoke device K registers the song ID of the song selected by the user in a reservation queue, thereby reserving the karaoke performance of the song.

[0029] The karaoke device K reads out accompaniment data from the storage means 10a based on the song ID registered in the reservation queue. The karaoke device K controls the performance means 10d to perform karaoke of the song based on the accompaniment data. The user sings karaoke along with the karaoke performance of the song.

[0030] When the karaoke performance of one song is completed, the confirmation unit 200 checks whether the song ID of another song (i.e., the song before the karaoke performance) is registered in the reservation queue. If the song ID of the other song is not registered in the reservation queue, the confirmation unit 200 outputs a signal to that effect to the calculation unit 300. On the other hand, if the song ID of the other song is registered in the reservation queue, the confirmation unit 200 performs the above-mentioned confirmation again after the karaoke performance of the other song is completed.

[0031] (Calculation section) If no karaoke performance of another song is reserved, the calculation unit 300 calculates the remaining time for which the karaoke room can be used based on the end time of the use of the karaoke room and the current time.

[0032] When a karaoke room is reserved, the store terminal transmits the usage end time of the karaoke room to the karaoke device installed in the karaoke room. The karaoke device K stores the received usage end time in the storage means 10a.

[0033] Here, when a signal is received indicating that no song IDs of other songs are registered in the reservation queue, the calculation unit 300 calculates the difference between the usage end time stored in the storage means 10a and the current time. The calculated difference corresponds to the remaining time that the karaoke room can be used. The current time can be obtained using a clock function that the karaoke device K is equipped with.

[0034] The calculation section 300 outputs the calculated remaining time (difference value) to the encore processing section 400.

[0035] (Encore Processing Division) If the calculated remaining time is shorter than the first available playable time and longer than the second available playable time, the encore processing unit 400 causes the sound emitting means to emit an encore sound.

[0036] The first available play time is a value obtained by adding up the play time of the song with the shortest play time among the songs included in the generated list and the predetermined time. A single value is set as the predetermined time. The predetermined time is preferably the play time of the song with the second shortest play time among the songs included in the generated list. The second available play time is a value corresponding to the play time of the song with the shortest play time among the songs included in the generated list. The first available play time and the second available play time are set at an appropriate timing after the generating unit 100 generates the list of songs and before the encore processing unit 400 starts processing.

[0037] The encore voice is a voice that encourages the user to sing karaoke. For example, the encore voice is a voice that simulates the voice uttered by the audience at an artist's live performance when requesting an encore. Data corresponding to the encore voice can be data recorded from the voices uttered by the audience at the live performance (voices from cheering or noisemakers) or data generated using publicly known technology (for example, JP-A-7-311586). The data corresponding to the encore voice is pre-stored in the storage means 10a. There may be only one piece of data corresponding to the encore voice, or there may be multiple pieces of data corresponding to different encore voices.

[0038] When receiving the input of the calculated remaining time, the encore processing unit 400 compares the remaining time with the first available playable time to determine whether the remaining time is shorter or not. Also, the encore processing unit 400 compares the remaining time with the second available playable time to determine whether the remaining time is longer or not.

[0039] If it is determined that the calculated remaining time is shorter than the first available play time and longer than the second available play time, the encore processing unit 400 reads data corresponding to the encore sound from the storage means 10a and plays it, thereby emitting the encore sound from the speaker 20. The encore processing unit 400 causes the encore sound to be emitted from the usage end time back by the second available play time.

[0040] ==About the operation of the karaoke device K== Next, a specific example of the operation of the karaoke device K in this embodiment will be described with reference to Fig. 4. Fig. 4 is a flow chart showing an example of the operation of the karaoke device K. In this example, as shown in Fig. 1, it is assumed that a user U uses the karaoke device K installed in a karaoke room R. It is also assumed that the karaoke device K has completed the login of the user U, i.e., the singing history of the user U is stored in the storage means 10a. It is also assumed that the karaoke device K has stored the end time of the use of the karaoke room R, "21:00", transmitted from the store terminal.

[0041] The generating unit 100 generates a list of songs that the user U has sung karaoke from the singing history of the user U stored in the storage means 10a (generating a list of songs; step 10).

[0042] The karaoke device K refers to the list generated in step 10, and sets a first available performance time which is the sum of the performance time of the song with the shortest performance time among the songs included in the generated list and the predetermined time, and sets a second available performance time which corresponds to the performance time of the song with the shortest performance time among the songs included in the generated list (setting the first available performance time and the second available performance time; step 11).

[0043] The user U operates the remote control device 50 to select a piece of music that he / she wishes to sing as karaoke. The karaoke device K reads out the accompaniment data of the selected piece of music from the storage means 10a and performs the karaoke of the piece of music (karaoke performance of the piece of music; step 12). The user U sings karaoke along with the karaoke performance of the piece of music.

[0044] When the karaoke performance of one song is finished, the confirmation unit 200 checks whether the karaoke performance of another song is reserved. If the karaoke performance of another song is not reserved (Y in step 13), the confirmation unit 200 outputs a signal to that effect to the calculation unit 300.

[0045] Calculation unit 300 calculates the remaining time during which karaoke room R can be used, based on the end time of use of karaoke room R and the current time (calculation of the remaining time during which karaoke room can be used; step 14).

[0046] If the remaining time calculated in step 14 is shorter than the first available performance time set in step 11 (Y in step 15) and if the remaining time calculated in step 14 is longer than the second available performance time set in step 11 (Y in step 16), the encore processing unit 400 causes the sound emitting means to emit an encore sound to encourage the user U to sing karaoke (emit encore sound; step 17). Note that the karaoke device K may perform the processes of steps 15 and 16 simultaneously or in the reverse order.

[0047] Specifically, the generating unit 100 generates a list L of songs shown in FIG. 3 by referring to song information included in the singing history of the singer U stored in the storage means 10a.

[0048] The karaoke device K sets a first available play time T1 (6 minutes 30 seconds) which is the sum of the play time "3 minutes" of the song Xn with the shortest play time among the songs included in the list L and the play time "3 minutes 30 seconds" of the song Xn-1 with the second shortest play time among the songs included in the list L. The karaoke device K also refers to the list L and sets a second available play time T2 (3 minutes) which is equivalent to the play time "3 minutes" of the song Xn with the shortest play time among the songs included in the list L.

[0049] After completing the login to the karaoke device K, the user U operates the remote control device 50 to select a piece of music Y that the user U wishes to sing as karaoke. The karaoke device K registers the music ID of the piece of music Y selected by the user U in a reservation queue, thereby reserving a karaoke performance of the piece of music Y.

[0050] The karaoke device K reads out accompaniment data from the storage means 10a based on the song ID registered in the reservation queue. The karaoke device K controls the performance means 10d to perform karaoke of the song Y based on the accompaniment data. The user U sings karaoke along with the karaoke performance of the song Y.

[0051] When the karaoke performance of song Y is finished, the confirmation unit 200 checks whether song IDs of other songs are registered in the reservation queue. In this example, it is assumed that song IDs of other songs are not registered in the reservation queue. In this case, the confirmation unit 200 outputs a signal to that effect to the calculation unit 300.

[0052] When receiving an input signal indicating that no other song IDs are registered in the reservation queue, the calculation unit 300 calculates the difference Dn between the end time of use "21:00" stored in the storage means 10a and the current time, and outputs the difference Dn to the encore processing unit 400.

[0053] The encore processing unit 400 compares the calculated remaining time (i.e., the value of the difference Dn) with the first available play time T1 (6 minutes 30 seconds) to determine whether the remaining time is shorter. The encore processing unit 400 also compares the remaining time (i.e., the value of the difference Dn) with the second available play time T2 (3 minutes) to determine whether the remaining time is longer. If it is determined that the calculated remaining time is shorter than the first available play time and longer than the second available play time, the encore processing unit 400 reads data corresponding to the encore sound from the storage means 10a and plays it back, thereby emitting the encore sound from the speaker 20.

[0054] For example, when the current time is "20:55", the value of the difference D1 calculated by the calculation unit 300 is "5 minutes". The encore processing unit 400 compares the value of the difference D1 (5 minutes) with the first available play time T1 and the second available play time T2. Here, the value of the difference D1 (5 minutes) is shorter than the first available play time T1 (6 minutes 30 seconds) and longer than the second available play time T2 (3 minutes). That is, the encore processing unit 400 determines that the calculated remaining time is shorter than the first available play time and longer than the second available play time. In this case, the encore processing unit 400 causes the speaker 20 to emit the encore sound from the current time "20:55" until the time preceding the usage end time "21:00" by the second available play time (3 minutes) (i.e., "20:57"). When the time preceding the usage end time by the second available play time arrives, the encore processing unit 400 can fade out the encore sound instead of ceasing the sound emission.

[0055] On the other hand, when the current time is "20:58", the value of the difference D2 calculated by the calculation unit 300 is "2 minutes". The encore processing unit 400 compares the value of the difference D2 (2 minutes) with the first available play time T1 and the second available play time T2. Here, the value of the difference D2 (2 minutes) is shorter than both the first available play time T1 (6 minutes 30 seconds) and the second available play time T2 (3 minutes). In other words, the encore processing unit 400 determines that the calculated remaining time is shorter than both the first available play time and the second available play time. In this case, the encore processing unit 400 does not emit the encore sound from the speaker 20.

[0056] Alternatively, when the current time is "20:50", the value of the difference D3 calculated by the calculation unit 300 is "10 minutes". The encore processing unit 400 compares the value of the difference D3 (10 minutes) with the first available play time T1 and the second available play time T2. Here, the value of the difference D3 (10 minutes) is longer than both the first available play time T1 (6 minutes 30 seconds) and the second available play time T2 (3 minutes). In other words, the encore processing unit 400 determines that the calculated remaining time is longer than both the first available play time and the second available play time. In this case as well, the encore processing unit 400 does not emit the encore sound from the speaker 20.

[0057] == Summary of the embodiment == As is clear from the above, the karaoke device K according to this embodiment is installed in a karaoke room R. The karaoke device K includes a generating unit 100 for generating a list of songs that a user has sung karaoke from the singing history of the user, a checking unit 200 for checking whether karaoke performance of another song is reserved when karaoke performance of one song is finished, a calculating unit 300 for calculating the remaining time for which the karaoke room can be used based on the end time of use of the karaoke room and the current time when karaoke performance of another song is not reserved, and an encore processing unit 400 for making a sound emitting means emit an encore sound to encourage the user to sing karaoke when the calculated remaining time is shorter than a first available performance time obtained by adding up the performance time of the song with the shortest performance time among the songs included in the generated list and a predetermined time and when the calculated remaining time is longer than a second available performance time corresponding to the performance time of the song with the shortest performance time among the songs included in the generated list.

[0058] According to such a karaoke device K, when karaoke performance of other songs is not reserved and the remaining time for which the karaoke room can be used is shorter than the first available time and longer than the second available time, an encore sound is emitted in the karaoke room. By emitting the encore sound when karaoke performance of other songs is not reserved, a situation similar to the singing of the last song in the main part of an artist's live performance can be created. Furthermore, by emitting the encore sound when the remaining time for which the karaoke room can be used is shorter than the first available time and longer than the second available time, the user can easily select a song included in the singing history (i.e., a song that is easy to sing) as the encore song. In other words, according to the karaoke device K of this embodiment, the atmosphere at the end of an artist's live performance can be reproduced.

[0059] In addition, in the karaoke device K according to the present embodiment, the predetermined time can be the playing time of the song with the second shortest playing time among the songs included in the generated list. In this case, the first available playing time is the sum of the playing time of the song with the shortest playing time and the playing time of the song with the second shortest playing time. By setting the first available playing time in this manner, it becomes possible to select a song for an encore closer to the end of the usage time.

[0060] In this embodiment, the case where there is one user has been described, but there may be multiple users. When there are multiple users, the generation unit 100 generates a list from the singing histories of the multiple users. When there are overlapping songs between the singing histories of the users, the generation unit 100 generates a list as one song. Furthermore, the song with the shortest performance time corresponds to the song with the shortest performance time among the singing histories of the multiple users.

[0061] <Variation 1> The encore processing section 400 can display a predetermined image on the display means in accordance with the encore sound.

[0062] The predetermined image is an image suitable for a request for an encore, such as the word "encore" or a moving image of people clapping, or an image of a darkened stage at a live venue. Data corresponding to the predetermined image is stored in advance in storage means 10a. There may be only one piece of data corresponding to the predetermined image, or there may be a plurality of pieces of data corresponding to different predetermined images.

[0063] The karaoke device K having such an encore processing section 400 can visually reproduce the atmosphere at the end of an artist's live performance.

[0064] <Variation 2> When the karaoke device K emits an encore sound, it can present the user with songs that can be sung as karaoke.

[0065] In this modification, the CPU executes a program stored in the memory, whereby the control means 10e functions as a generation unit 100, a confirmation unit 200, a calculation unit 300, an encore processing unit 400, and a presentation unit 500 (see FIG. 5).

[0066] (Presentation part) When an encore sound is generated, the presenting unit 500 presents to the user those songs included in the generated list that can be karaoke-played by the end time of the usage.

[0067] The songs can be presented in various ways. For example, the presenting unit 500 can display the names of songs that can be played as karaoke by the end of the usage on the display screen of the display device 30 or the remote control device 50.

[0068] When an encore sound is generated, the presentation unit 500 checks the remaining time by referring to the current time and the end time of the use of the karaoke room. The presentation unit 500 presents to the user, from among the songs included in the generated list, songs that can be played as karaoke by the end time of the use (i.e., songs whose playing time is within the remaining time).

[0069] For example, as described in the embodiment, it is assumed that the encore processing unit 400 emits an encore sound from the current time "20:55."

[0070] In this case, the presentation unit 500 references the current time "20:55" and the end time of the karaoke room usage "21:00" and confirms that the remaining time is "5 minutes." Then, the presentation unit 500 determines, from among the songs included in the generated list L, songs Xn-4 to Xn that can be played as karaoke by the end time of the usage (i.e., songs with a playing time of 5 minutes or less). The presentation unit 500 causes the display screen of the remote control device 50 to display the song titles of songs Xn-4 to Xn.

[0071] When the encore sound is started, the remaining time until the end of the usage time gradually becomes shorter. Therefore, if a song presented immediately after the encore sound is started is selected later, the playing time may not be enough at that time. Therefore, the presentation unit 500 may change the song to be presented depending on the remaining time for using the karaoke room.

[0072] After the encore sound is emitted, the presentation unit 500 checks the remaining time by referring to the current time and the end time of the karaoke room at predetermined intervals (for example, every 10 seconds). At the predetermined interval, the presentation unit 500 determines, from among the songs included in the generated list, songs that can be played as karaoke by the end time of the use (i.e., songs whose playing time is within the remaining time), and replaces the songs already presented.

[0073] For example, as described in the above example, it is assumed that the presentation unit 500 has caused the titles of songs Xn-4 to Xn to be displayed on the display screen of the remote control device 50. One minute later (i.e., "20:56"), the presentation unit 500 references the current time "20:56" and the end time of the use of the karaoke room "21:00" and confirms that the remaining time is "4 minutes". Of the songs included in the generated list L, the presentation unit 500 determines songs Xn-2 to Xn that can be played as karaoke by the end time of the use (i.e., songs with a performance time of 4 minutes or less). The presentation unit 500 changes the names of the currently presented songs Xn-4 to Xn to the names of songs Xn-2 to Xn.

[0074] As is clear from the above, the karaoke device K according to this modification has a presentation unit 500 that, when an encore sound is generated, presents to the user songs that can be karaoke-sung by the end of the usage time from among the songs included in the generated list. The presentation unit 500 can also change the songs to be presented depending on the remaining time for which the karaoke room can be used. With such a karaoke device K, when an encore sound is generated, it is possible to encourage the user to sing karaoke songs that can be karaoke-sung by the end of the usage time.

[0075] Instead of changing the music to be presented, the presentation unit 500 can present a message to the effect that the music cannot be reserved when the user selects a music piece that does not have enough playing time. The presentation unit 500 can also present a message to the effect that the user cannot select any music pieces after the second predetermined time has passed since the end time of the use.

[0076] <Other> The above embodiment is presented as an example, and does 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 gist of the invention. The above embodiment and its modifications are included in the scope of the invention and its equivalents described in the claims, as well as the scope and gist of the invention.
