Further, in the following description, well-known arts will not be described in detail if it appears that they could obscure the invention in unnecessary detail. Hereinafter, preferred embodiments of the present invention will be set forth in detail with reference to the accompanying drawings.
In the present invention, portable song accompaniment apparatus is configured and operated in three kinds of cases. Referring to a configuration shown in Fig.2, each case will be described.
Firstly, a user practices singing a song by operating only a portable accompaniment device 50. This case includes an environment not having a fixed type supporting device 70, an environment where there is no a video device 81 connected to the fixed type supporting device 70, an environment where there is no an audio device 82 connected to the fixed type supporting device, and an environment where an audio device 82 can not be used through an FM transmission/receiving function without being connected to the fixed type supporting device 70.
In the first case, an audio signal such as accompaniment is outputted through an audio output unit 54 included in the portable accompaniment device 50, and displays image signal such as the words of a song on a picture displaying unit 53 included in the portable accompaniment device 50.
Additionally, in case that the picture displaying unit 53 is not included in the portable accompaniment device 50, it is preferred to convert/display various image information such as the words of a song, a background picture, accompaniment information, an information picture which were displayed on the picture displaying unit 53 into an audio signal (preferably, digital audio signal, e.g., MP3, AAC, WMA etc), and output them through an audio output unit 54.
Secondarily, the portable accompaniment device 50 and the audio device 82 are operated by an FM transmitting/receiving function so that a user practice singing a song. As an example of this case, there are an environment where there is no a fixed type supporting device 70, an environment where there is no communication connection between the fixed type supporting device 70 and the audio device 82, an environment where the portable accompaniment device 50 does not have the audio output unit 54 and an environment where the audio device 82 is used instead of the audio output unit 54 included in the portable accompaniment device 50. In the second case, an audio signal, e.g., accompaniment is transmitted to the audio device 82 through an FM transmitting unit 58 included in the portable accompaniment device 50 so that an audio signal is outputted through the audio device 82. In third, the portable accompaniment device 50 and the fixed type supporting device 70 are operated by a wireless transmitting/receiving function so that a user practice singing a song. This case includes an environment where there is a fixed type supporting device 70, and the video device 81 and the audio device 82 which are included in the fixed type supporting device 70.

Meanwhile, a fixed type supporting device 70 in accordance with an embodiment of the present invention includes a wireless transceiving unit 71, an image processing unit 72, an audio processing unit, a data storage unit 74, an internet connection unit 75 and a control unit 76. Also, the fixed type supporting device 70 may be selectively connected to a video device 81 for displaying the words of song and a background picture, and an audio device 82 for outputting an audio sound such as accompaniment. It is preferred that the audio device 82 has an FM receiving unit 83.
Meanwhile, in the embodiment of the present invention, a central management server 90 and a DB 91 which are connected to the fixed type supporting device 70 are operated by a portable accompaniment device (preferably, a fixed type supporting device) manufacturer through an internet.
In the present invention, while a user carries out only a small size portable accompaniment device 50 without carrying out a fixed type accompaniment device 70, a user may practice singing a song through the video device 81 and the audio device 82 included in the fixed type supporting device 70 by connecting the portable accompaniment device 50 to the fixed type supporting device 70 installed on a specific place in case that the user wants to practice singing a song.
Moreover, in the present invention, the portable accompaniment device 50 and/or the fixed type supporting device 70 updates device information based on the information received from the central management server 90. The portable accompaniment device 50 and/or the fixed type supporting device 70 read and use song data stored in the DB 91 of the central management server 90 by connecting the fixed type supporting device 70 to the central management server 90 through an Internet according to a request of the user. The central management server 90 collects device/user information based on the information received from the portable accompaniment device 50 and/or the fixed type supporting device 70, and performs a function limitation/user operation limitation of the portable accompaniment device 50 and/or fixed type supporting device 70.
In the present invention, the portable accompaniment device 50 decreases its size by having a minimum function for performing a song accompaniment, and transmits basic image and audio information to the fixed type supporting device 70 so that the fixed type supporting device 70 processes the received information. Particularly, in the present invention, in state that the portable accompaniment device 50 stores only image indication information to indicate image data (e.g., which background of a moving picture is displayed) and minimum image information (e.g., a title of song, words of a song, accompaniment information, a displaying position, a displaying color, and a font size) except an image source file, e.g., TEXT, Joint Photographic Coding Experts Group (JPEG), Graphics Interchange Format (GIF), Audio Video Interleaving (AVI), MOV, the portable accompaniment device 50 transmits the image indication information and the minimum image information to the fixed type supporting device 70 so that the fixed type supporting device 70 generates and processes the corresponding image data when the song accompaniment function is performed. Hereinafter, the above mentioned various technical points will be described in detail with reference to each component shown in Fig. 2.
The portable accompaniment device 50 will be described as follows.
The mic 51 is a unit for inputting an audio signal, which is inputted by a user, to a control unit 60.
The key input unit 52 is a unit for inputting a key signal, which is inputted by a user, to the control unit 60 through a plurality of key buttons, and may include combination of a device power on/off button, a song start/end button, a scroll button, a hot key button for a specific function (e.g., a special button for searching a song), a numerical button and a character button. The picture displaying unit 53 is a unit for displaying simple image data, e.g., the number of a song, a title of a song, words of a song and a short expression, and is implemented by a Super Twisted Nematic Liquid Crystal Display (STN LCD), a Thin Film Transistor-Liquid Crystal Display (TFT-LCD), an inorganic Electroluminescence (EL), an Organic Light Emitting Diode (OLED) and a Plasma Display Panel (PDP). It is preferable that the picture displaying unit 53 having a corresponding screen size is attached to the portable accompaniment device 50 based on a size of the portable accompaniment device 50.
The audio output unit 54 is a unit for outputting simple audio data, e.g., guide announcement of menu description, guide announcement of device operating method description, a title of a song, words of a song, accompaniment and a song start/end alarm sound, and may include combination of a single speaker, a dual speaker, a stereo type speaker, an earphone and a headset.
The data storage unit 55 stores minimum data for performing a song accompaniment function. For example, the data storage unit 55 stores not an audio source file (e.g., MPEG layer 3 (MP3), Musical Instrument Digital Interface (MID), Windows Media Audio (WMA), etc) for all songs but a preference song, and not all image source files but the image indication information (e.g., location which background of a moving picture is displayed) and minimum image information (e.g., a title of song, words of a song, accompaniment information, a displaying position, a displaying color, and a font size). Here, the data storage unit 55 of the portable accompaniment device 50 does not need a high capacitance. On the other hand, in case that all song data are not stored in the portable accompaniment device 50, it will be described below that the portable accompaniment device 50 receives and uses song data requested by a user from the data storage unit 55 the fixed type supporting device 70 or the DB 91 of the central management server 90.
Also, the portable accompaniment device 50 further may include a sub storage medium. For example, it is preferable that the sub storage medium is detachably connected to the portable accompaniment device 50 in case that the accompaniment data received from the fixed type supporting device 70 has a large file size or needs an extra storage space for processing the accompaniment data when the accompaniment data received from the fixed type supporting device 70 is played.
The battery 56 is a unit for providing a power, which drives the portable accompaniment device, to the portable accompaniment device, and may be implemented by a dry cell, a recharger, or a DC-DC converter which provides a power provided from an external device through an adapter. Meanwhile, as described below, the battery 56 does not need a high output and high capacity since a power consumption quantity of the inner components is small and an operation quantity of the portable accompaniment device 50 of the present invention is small.
The accompaniment processing unit 57 generates a corresponding accompaniment based on audio source file such as MIDI, PCM, MP3, WMA and OGG provided from the data storage unit 55, the fixed type supporting device 70 or the central management server 90 through the fixed type supporting device 70 by a control of the control unit 60, and mixes accompaniment signal with a user audio signal inputted in the mic 51. Further, the accompaniment processing unit 57 performs a musical function such as a musical effect (e.g., a chorus), a melody adjustment, a tempo change, a musical interval adjustment, a rhythm change, a syllable/phrase management and a song ending process. The FM transmitting unit 58 transmits the mixed signal (singer's voice sound + accompaniment), which is generated and processed in the accompaniment processing unit 57 by the control of the control unit 60, to the FM receiving unit 83 of the audio device 82 through a wireless communication. Thus, the FM receiver 83 transmits and outputs the mixed signal (singer's voice sound + accompaniment) received from the portable accompaniment device 50 to the audio device 82.
The wireless transceiving unit 59 transmits the image information and audio information and the other information stored in the data storage unit 55 to the fixed type supporting device 70 through a wireless communication by a control of the control unit, and receives various information such as audio source file and device upgrade information from the fixed type supporting device 70 and/or the central management server 90 via the fixed type supporting device 70. Each of the wireless transceiving unit 59 of the portable accompaniment device 50 and the wireless transceiving unit 71 of the fixed type supporting device 70 may transceive data through a Bluetooth, a zigbee, an IrDA communication and the like.
As mentioned previously, the portable accompaniment device 50 transmits all kinds of information to the fixed type supporting device 60. Particularly, when the song accompaniment function is performed, the control unit 60 of the portable accompaniment device 50 enables the image indication information to indicate image data (e.g., location which background of a moving picture is displayed) and the minimum image information (e.g., a title of song, words of a song, accompaniment information, a displaying position, a displaying color, and a font size) to be transmitted to the fixed type supporting device 70 through the wireless transceiving unit 59. The image indication information and the minimum image information transceiving, processing and the like will be described in detail below.
Meanwhile, in another embodiment of the present invention, the audio signal, which is processed in the accompaniment processing unit 57 by the control of the control unit 60 may be transmitted to the fixed type supporting device 70 through the wireless transceiving unit 59 without installing the FM transmitting unit 58 for transmitting the audio signal [signer's voice sound + accompaniment] on the portable accompaniment device 50. Thus, the fixed type supporting device 70 processes, transmits and outputs the audio signal received from the portable accompaniment device 50 through the audio processing unit 73 of the fixed type supporting device 70. In another embodiment, the FM transceiving unit may not be included in the portable accompaniment device 50 and the audio device 82.
On the other hand, the fixed type supporting device 70 will be described as follows. The control unit 76 processes various kinds information received from the portable accompaniment device 50 through the wireless transceiving unit 71. Particularly, when the song accompaniment function is performed, the control unit 76 searches the image source file (e.g., background moving picture file and the like) corresponding to the image indication information received from the portable accompaniment device 50, in the data storage unit 74. The control unit 76 enables the background picture to be displayed on the video device 81 by processing the image source file in the image processing unit 72.
