  SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an audio device capable of searching for an attribute item of a music not included in the alphabet included in the list transferred from the portable player by reading the attribute item in alphabetical notation. And

  In order to achieve the above object, the present invention represents an audio device that can be connected to a portable device in which music is stored, with a non-alphabetic character used in a language used in the language environment of the portable device. A list of attribute character strings, which are character strings representing predetermined attributes of each music stored in the portable device, is acquired from the conversion table storage unit storing the conversion table in which the readings are registered and the connected portable device. A list acquisition unit and a search unit are provided. However, the search part is an attribute character string that includes an alphabetic character designated by the user as a designated character and that has the designated character at the beginning and a non-alphabetic character that is included in the attribute character string. The attribute string after conversion, which is a character string obtained by converting the non-alphabetic characters to be read with the alphabetic characters obtained by referring to the conversion table, to the attribute character string having the specified character at the beginning, An attribute character string corresponding to the search target attribute character string is searched from among the attribute character strings included in the list as a target search target attribute character string.

  According to such an audio device, a search for an attribute character string including a non-alphabetic character included in a list obtained from a portable device is converted into a reading in which the non-alphabetic character of the attribute character string is represented by an alphabetic character. The search can be performed by searching for the converted attribute character string. Therefore, it is possible to perform a search by reading an attribute character string including non-alphabetic characters included in the list, in alphabetic characters.

  In this audio apparatus, the audio apparatus includes a display device and a list display unit that displays a partial range of the list on the device, and the search unit includes the list included in the list. The attribute character string corresponding to the search target attribute character string in the earliest order is searched, and the list display unit displays a range starting from the attribute character string searched by the search unit in the list You may comprise.

  Alternatively, in the audio device, the conversion table storage unit is provided corresponding to each of a plurality of languages, and the non-alphabetic characters used in the corresponding languages are registered in alphabetical readings. The list that can be acquired from the portable device that uses the language as a language environment for the display device and each of a plurality of languages is stored in the audio table, is a character code order list, or a mixed order. A list type table storage unit that stores a list type table in which identification of whether it is a list, a language identification acquisition unit that acquires identification of a language used in the language environment of the portable device from the connected portable device, A list display section for displaying a partial range of the list on the display device. It may be. However, the character code order list is a list in which the attribute character strings of the music pieces are registered in the order of the character code, and the mixed order list is a non-alphabetic character in the attribute character strings of the music pieces. This is a list in which the attribute character strings of the music pieces are registered in the order of the character codes of the character strings replaced with alphabetic characters representing the readings of In addition, when the identification of the mixed order list is registered in the list type table for the language represented by the identification acquired by the language identification acquisition unit, the search unit includes non-alphabetic characters included in the attribute character string. Is converted into a character string that is converted into a reading expressed in alphabets obtained by referring to the conversion table corresponding to the language represented by the identification acquired by the language identification acquisition unit, as the converted attribute character string of the attribute character string, The list type is searched for an attribute character string corresponding to the search target attribute character string that is included in the list and is in the earliest order in the list, and for the language represented by the identification acquired by the language identification acquisition unit When the identification of the character code order list is registered in the table, the specified character included in the list is the first in the list and has the specified character at the head. It is intended to search for sex string. The list display unit displays a range of the list starting from the attribute character string searched by the search unit.

  Here, the language used in the language environment of the portable device is assumed to include simplified characters, the non-alphabetic characters used in the simplified language are assumed to be simplified characters, and the simplified characters expressed as alphabetic characters are read as follows: It may be pinyin of the simplified character. In this case, the list that can be acquired from the portable device that uses simplified characters as a language environment may be the mixed order list.

  In addition, the audio device that displays the partial range of the list described above receives selection of an attribute character string in the partial range of the list displayed on the display device, and the connected audio device is It is also possible to provide a music playback unit that controls and plays back music whose attribute character string has received the selection.

  According to the audio device that displays a partial range of these lists, the list obtained from the portable device has replaced the non-alphabetic characters in the attribute string of each song with the alphabetic characters representing the reading of the characters. When the attribute character string of each song is registered in the order of the character code of the character string, the display range of the list is set correctly, the alphabet character designated by the user is replaced with the first part of the attribute character string or It can be set so that the first attribute character string in the range of the attribute character string at the beginning of the alphabetical reading of the attribute character string is the first attribute character string in the display range.

  In addition, in the audio device, the conversion table storage unit is provided corresponding to each of a plurality of languages, and the alphabetic reading of each non-alphabetic character used in each corresponding language is registered. A translation table, and a language identification acquisition unit that acquires, from the portable device connected to the audio device, a language identification acquisition unit used in a language environment of the portable device. A non-alphabetic character included in the character string obtained by converting the non-alphabetic character into a reading represented by the alphabet obtained by referring to the conversion table corresponding to the language represented by the identification acquired by the language identification acquisition unit A post-conversion attribute character string may be used.

  In this case, the audio device is provided with a display device, and in the search unit, all the attribute character strings corresponding to the search target attribute character string included in the list are searched and extracted, and extracted.

It is a figure which shows the alphabet conversion database which concerns on embodiment of this invention. It is a figure which shows the title list which concerns on embodiment of this invention. It is a figure which shows the example of a display of the player screen which concerns on embodiment of this invention. It is a flowchart which shows the title list jump process which concerns on embodiment of this invention. It is a figure which shows the example of a display of the player screen which concerns on embodiment of this invention.

Hereinafter, embodiments of the present invention will be described.
FIG. 1 shows the configuration of an audio apparatus according to this embodiment.
The audio device 1 is an on-vehicle audio device 1 mounted in, for example, an automobile, and as illustrated, an input device 101, a display device 102, an audio output device 103 that outputs audio, a storage device 104, a radio receiver 105, Other peripheral devices 106, an external interface 107, an operating system 110, and applications running on the operating system are provided.

The portable player 2 can be connected to the external interface 107 of the audio apparatus 1 via a wired communication interface or a short-range wireless interface.
In addition, the audio device 1 plays the music player 111 and the radio receiver 105 that control the reproduction output of music stored in the portable player 2 connected to the external interface 107 and music stored in the storage device 104 as applications. A radio controller 112 that controls output and other applications 113 are provided.

Next, the alphabet conversion database stored in advance in the storage device 104 of the audio apparatus 1 will be described.
As shown in FIG. 2, the alphabet conversion database stores a sort key and a conversion table corresponding to each language that can be used as a language environment provided by the portable player 2. Here, the language used in the language environment of the portable player 2 is a language that is preferentially used in the user interface of the portable player 2. For example, the portable player 2 uses the names of various menus and various items in the language environment. Display in the language set as the language used in. Note that the language setting used in the language environment of the portable player 2 can usually be arbitrarily changed by the user.
Next, as a sort key, a list of attribute items, which are character strings representing attributes such as the titles of songs, albums, and artists, used by the portable player 2 of the corresponding language, is a list in which the attribute items are sorted in the order of character codes. "Character code" to indicate that there is a list of attribute items. For attribute items in alphabetical notation, the attribute item is used. One of “alphabet” representing that the attribute items are sorted in alphabetical order calculated by using “alphabet” is registered.

  Next, in the conversion table corresponding to the language in which “alphabet” is registered as the sort key, the readings of the non-alphabetic characters in the corresponding language are registered for each of the non-alphabetic characters.

  That is, for example, in the portable player 2 in which the language in which “alphabet” is registered in the sort key is “simplified characters” and the language used in the language environment is simplified characters, as an attribute item list, In addition to using the attribute item, for a simplified attribute item, when using a list in which the attribute item is sorted in alphabetical order calculated using a character string expressed in alphabet by pinyin instead of the attribute item, the conversion table includes: Each pinyin of simplified characters is registered.

  In addition, in the conversion table corresponding to the language in which “character code” is registered in the sort key, the alphabet of the non-alphabetic phonetic character used for notation of the attribute item in the attribute item list of the portable player 2 of the corresponding language. The reading of the notation is selectively registered.

  That is, for example, in the portable player 2 in which the language in which “character code” is registered in the sort key is “Japanese” and the language used in the language environment is “Japanese”, the attribute item is displayed as a list of attribute items. When using a list in which the characters are sorted in the character code order, for each character of katakana, the Roman alphabet (for example, Hebon Roman alphabet) of the character is registered. However, in English, when a plurality of alphabets are used as alphabets having the reading of the characters, a plurality of alphabets may be registered for the characters. For example, “RA” and “LA” may be registered for “La”, and “ZA” and “THE” may be registered for “The”.

  Returning to FIG. 1, when the portable player 2 is connected to the external interface 107, the music player 111 of the audio apparatus 1 receives music stored in the portable player 2 provided by the portable player 2 from the portable player 2. A process of acquiring a list of attribute items and a language code that is set in the portable player 2 and that represents a language that is set as a language used in the language environment of the portable player 2 is stored in the storage device 104.

  Here, the list of attribute items of music provided by the portable player 2 includes a title list that is a list of music titles, an album list that is a list of music albums, an artist list that is a list of music artists, and the like. There is.

  FIG. 3a shows an example of a title list provided by the portable player 2 in which the language used in the language environment is set to “Simplified”, and as shown, the portable in which the language is set to “Simplified”. The player 2 provides the audio apparatus 1 with a title list in which the titles are arranged in the order in which the titles are sorted in alphabetical order by replacing the simplified titles with the titles expressed in alphabets by pinyin as the title list of the music.

  FIG. 3b shows an example of a title list provided by the portable player 2 whose language is set to “Japanese”. As shown in the figure, the portable player whose language is set to “Japanese”. 2 provides the audio apparatus 1 with a title list in which the titles are arranged in the order in which the titles are sorted in the character code order as the title list of the music.

  When the music player 111 of the audio device 1 is instructed by the user to start playback of the connected portable player 2 via the input device 101, the music player 111 stores the portable player 2 from the portable player 2 stored in the storage device 104. A player screen including a list corresponding to the mode set by the user in the acquired list of attribute items is displayed on the display device 102.

  FIG. 4 a shows the player screen 400 when the title mode is set. The player screen 400 is provided with a title list display area 401, and the title list display area 401 contains a title list display area 401. A part of the range is displayed in a scrollable form. In addition, the player screen 400 is provided with a jump button 402, a search button 403, and a menu button 403 for displaying a menu for accepting a mode setting change operation. In addition to the title mode, an album mode for displaying an album list on the player screen 400, an artist mode for displaying an artist list on the player screen 400, and the like are provided as modes.

  Then, the music player 111 accepts the selection of the attribute item from the user on the portion of the attribute item list displayed on the player screen 400 in this way, and is selected in response to the user's reproduction start operation. The portable player 2 connected to the portable player 2 is instructed to start playing a song having the attribute item, and the song output from the portable player 2 is output from the audio output device 103.

  On the other hand, if the portable player 2 is instructed to start playback from the music player 111 of the audio device 1, the portable player 2 starts the playback operation of the music having the specified attribute item and transfers the played music to the audio device 1. Do.

  Hereinafter, in such an audio apparatus 1, when the jump button 402 on the player screen 400 is operated, the music player 111 sets the display range of the list displayed on the player screen 400 to a character designated by the user. A list jump process is performed for scrolling so that the attribute item having the first character that matches is displayed at the top.

  Here, when the list displayed on the player screen 400 is a title list, the music player 111 performs a title list jump process as a list jump process, and the list displayed on the player screen 400 is an album list. If it is a list, album list jump processing is performed as list jump processing. If the list displayed in the player screen 400 is an artist list, artist list jump processing is performed as list jump processing.

  Here, the title list jump process, the album list jump process, and the artist list jump process are different from the title list, the album list, and the artist list. As a representative, list jump processing will be described.

FIG. 5 shows the procedure of the title list jump process.
As shown in the figure, the music player 111 starts the title list jump process if the jump button 402 is operated when the list displayed on the player screen 400 is the title list, and is shown in FIG. 4b. As described above, the designated character reception window 410 is displayed on the display device 102, the input of the character is received, and the character that has received the input is set as the specified character (step 502). Here, it is assumed that the tuttle list jump process accepts only one character as a designated character.

  Then, as described above, it is checked whether or not “alphabet” is registered in the alphabet conversion database as a sort key for the language codes set in the portable player 2 acquired from the portable player 2 when the portable player 2 is connected (step S1). 504).

  If “alphabet” is not registered as the sort key, the designated character is set as the search character (step 534), and the titles in the title list stored in the storage device 104 among the titles having the search character as the front part are set. The title having the earliest registration order is searched (step 536).

  Next, when the search is completed, it is checked whether the search is successful (step 538). If the search fails because the title having the search character as a forward portion is not included in the title list, the search is performed. The character is set to the first character of the current search character in the character code order (step 542), and the processing returns to step 536.

On the other hand, if the search is successful (step 538), the order in the title list stored in the storage device 104 of the searched title is set as the ID (step 540).
Then, the range of the title list displayed in the title list display area 401 in the player screen 400 is changed so that the title with the ID in the order in the title list is displayed at the top (step 532), and the title list jump process is performed. Exit.

  On the other hand, when “alphabet” is registered in the alphabet conversion database as the sort key for the language code set in the portable player 2 (step 504), the following processing is performed.

  That is, first, the character code in the order preceding the designated character is set as the search character (step 506), and the title list stored in the storage device 104 among the titles having the search character as the front part. The title with the latest registration order is searched for (step 508).

  Then, it is checked whether or not the search is successful (step 510). If the search fails because the title having the search character as a forward portion is not included in the title list, the search character is assigned the current character code order. (Step 544), and the process returns to step 508.

On the other hand, if the search is successful (step 510), the order in the title list stored in the storage device 104 of the searched title is set to S (step 512).
Next, the next character after the designated character in the character code order is set as the search character (step 514), and among the titles having the search character as the front part, the title list stored in the storage device 104 The title with the earliest registration order is searched (step 516).

  Then, it is checked whether or not the search has succeeded (step 518). When the search fails because the title having the search character as a forward portion is not included in the title list, the search character is displayed in the current character code order. (Step 546), the process returns to step 516.

On the other hand, if the search is successful (step 518), the order in the title list stored in the storage device 104 of the searched title is set to E (step 520).
Next, if S and E are set as described above, none of the titles in the order of S + 1 to E-1 in the title list stored in the storage device 104 is written in alphabet. A title list in which titles are replaced with alphabetic titles is created as a work title list (step 522).

Here, titles that are not written in alphabet are replaced with alphabets using a conversion table registered in the alphabet conversion database for the language code set in the portable player 2. It is generated by replacing a non-alphabetic character in a title that has not been made with an alphabetic character string (a reading in alphabetical notation) representing the reading.
However, here, only one character is accepted as the designated character in the title list jump process as described above. In this case, only the title whose first character is not an alphabetic character is regarded as a title that is not written in the alphabet. In addition to replacing with titles written in alphabet, and replacing titles that are not written in alphabet with alphabetic titles, only the first character of titles that are not written in alphabet is the alphabet string that indicates the reading. You may make it produce | generate by replacing with (reading of an alphabet notation).

  Then, the designated character is set as a search character (step 524), and the title having the earliest registration order in the work title list among the titles having the search character as a front portion is searched (step 526).

  Then, it is checked whether or not the search is successful (step 528). If the search fails because the title having the search character as a forward portion is not included in the work title list, E is set as the ID (step 548). ) The range of the title list displayed in the title list display area 401 in the player screen 400 is changed so that the title with the ID in the order in the title list is displayed at the top (step 532), and the title list jump process Exit.

  On the other hand, if the search is successful, the order of the titles in the title list stored in the storage device 104 of the titles in the searched work title list is set as the ID (step 530).

  If the title searched from the work title list is a title expressed in alphabet by replacing a title not expressed in alphabet, the order in the title list stored in the storage device 104 of the replacement source title is ID.

  Then, the range of the title list displayed in the title list display area 401 in the player screen 400 is changed so that the title with the ID in the order in the title list is displayed at the top (step 532), and the title list jump process is performed. Exit.

The title list jump process has been described above.
According to such title list jump processing, titles that are sorted from the portable player 2 in the alphabetical order calculated by using the alphabetical representation of the non-alphabetic notation as a title list instead of the title as the title list. Even if a list is provided, the title that has the character specified by the user in the front part correctly and the title that has the character specified by the user in the front part of the alphabetical reading are the most. A range starting from the title previously registered in the title list can be set as the range of the title list displayed in the title list display area 401.

  That is, for example, the title list acquired from the portable player 2 in which “simplified characters” is set as the language code and stored in the storage device 104 is shown in FIG. 3A, and the alphabet conversion database is shown in FIG. 2B. In this case, when the title list is displayed on the player screen 400, when the user operates the jump button 402 and inputs “H” as a designated character, as shown in FIG. Display title list with the title in the title list registered first in the head of the English title and the simplified character with "H" as the front part of the alphabetic reading (pinyin) In addition, the display of the title list display area 401 on the player screen 400 is updated.

  4d is shown as a comparative example, and the title list acquired from the portable player 2 in which “simplified characters” is set as the language code and stored in the storage device 104 is as shown in FIG. 3a. In addition, when the title list is displayed on the player screen 400 and the user operates the jump button 402 and inputs “H” as the designated character, the titles having “H” as the front portion are displayed. The player screen 400 when the display of the title list display area 401 of the player screen 400 is updated to the display of the title list in which the title with the earliest registration order of the title list is arranged at the top is shown.

  As shown by comparison between FIGS. 4c and 4d, in the display of FIG. 4d, the title with the simplified character having “H” as the front part of the alphabetic reading (pinyin) is displayed in the title list display area 401. The user is out of the range of the list, and the user cannot even know that the title of the simplified Chinese character exists.

  As described above, the album list jump process / artist list jump process is the same as the title list jump process. In the title list jump process, the title list is changed to the album list / artist list, and the title is changed to album / It corresponds to the process replaced with an artist.

The operation of the title list jump process has been described above.
Now, when the search button 403 on the player screen 400 is operated, the music player 111 of the audio apparatus 1 performs a search process for displaying a list of attribute items having a character that matches the character specified by the user at the head. .

  Here, when the list displayed on the player screen 400 is a title list, the music player 111 searches for a title having a character that matches the character specified by the user as a search process as a search process. When the list displayed in the player screen 400 is an album list, an album search process is performed as a search process to search for an album having a character that matches the character specified by the user at the head, When the list displayed in the player screen 400 is an artist list, an artist search process is performed as a search process to search for an artist having a character that matches the character specified by the user at the head.

  Here, in the title search process, album search process, and artist search process, the list / search target to be processed is only different from the title list / title, album list / album, and artist list / artist. The title search process will be described as a representative in the search process.

  In the title search process, first, as shown in FIG. 4B, a designated character reception window 410 is displayed on the display device 102, input of an arbitrary character is received, and the character that has been input is set as a specified character.

Then, a title having the designated character as a front portion is searched from the title list stored in the storage device 104 and set as a search title.
Next, with reference to the conversion table registered in the alphabet conversion database for the language set as the language used in the language environment of the portable player 2, the reading of the alphabet notation in which the designated character matches the front part is read. Calculate the non-alphabetic characters you have. That is, for example, if the language code set in the portable player 2 is “Japanese” and the designated character is “n”, the conversion table of “Japanese” in the alphabet conversion database shown in FIG. Since “na”, “ni”, “nu”,... correspond to readings in alphabetical notation with n in the front part, the non-alphabetic characters “na” registered in the “Japanese” conversion table, Calculate “d”, “nu”, and so on.

Then, a title having the calculated non-alphabetic character as a front portion is searched from the title list stored in the storage device 104 and added to the search title.
Then, as shown in FIG. 6, the list displayed on the player screen 400 is changed to a search title list.
The title search process has been described above.
According to such a title search process, for example, the alphabet conversion database is as shown in FIG. 2B, and the title acquired from the portable player 2 in which “Japanese” is set as the language code and stored in the storage device 104 is stored. When the list is as shown in FIG. 3B and the title list is displayed on the player screen 400, when the user operates the search button 403 and inputs “H” as a designated character, “H” is displayed. In addition to the English title having the front part, a Japanese title having “H” as the front part of the alphabetic reading is searched and displayed in a list on the player screen 400 as shown in FIG. Become.
Note that the music player 111 accepts selection of a title from the user on the search title list displayed on the player screen 400 as shown in FIG. 6 and is selected in response to the user's playback start operation. The portable player 2 connected to the portable player 2 is instructed to start playing a song with a certain title, and the music output from the portable player 2 is output from the audio output device 103.

  As described above, the album search process / artist search process is the same as the title search process. In the title search process, the title list is replaced with the album list / artist list and the title is replaced with the album / artist. It corresponds to processing.

The embodiment of the present invention has been described above.
By the way, in the above embodiment, one character is received from the user as a designated character, and the list jump process and the search process are performed. The above-described processing may be performed using the received character string instead of the designated character.
