Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The term "unit", as used herein, is intended to refer to a computer-related entity, either hardware, firmware, a combination of hardware and software, or software in execution. For example, a unit may be, but is not limited to being: a processing object running on a processor, an executable, a thread of execution, a program, and/or a computer.

According to the music player and the music playing method provided by the embodiment of the invention, the music file with higher audio quality can be selected from multiple versions of the same song to be played without reading the information of all music files stored in the storage medium in advance, so that the use experience of a user is improved.

The music player provided by the embodiment of the invention can be internally provided with a storage space for storing music files; the storage space of the external storage device may also be used for storing music files, for example, the music files are stored in the external storage device such as a U-disk or an SD card, and the music player obtains the music files by reading data in the external storage device when playing music.

As shown in fig. 1, an embodiment of the invention provides a structural schematic diagram of a music player. Wherein: the music player 10 includes: an acquisition unit 101, a playing unit 102, and an updating unit 103. Wherein:

an obtaining unit 101 is used for obtaining a playing instruction. The playing instruction is used for instructing the music player to determine the music file to be played.

Specifically, the playing instruction may be generated according to an operation of a user selecting a certain music file, or may be selected according to a preset playing sequence when the music player finishes playing a song or will finish playing a song.

For example, assume that the music files stored in the storage space are as shown in table 1 below:

TABLE 1

It can be seen that five music files are stored in the storage space, and the music information of music file No. 01 includes: the song name "aaa", the album name "ee", the singer "abc", the music genre "f", the audio quality represented by the bit rate of the audio and the bit rate "192 kbps", and the other four music files are the same.

If the user triggers a corresponding playing instruction when clicking the icon corresponding to the music file No. 03 in table 1, the music player determines that the music file to be played is the music file No. 03 in table 1 according to the playing instruction. Or, when the music player plays music according to the predetermined playing sequence, if it is determined that the next music file to be played is the music file No. 03, generating an indication according to the predetermined playing sequence, so that the music player determines that the music file to be played is the music file No. 03 in table 1.

The playing unit 102 is configured to, after the obtaining unit obtains the playing instruction, if it is determined that at least one first music file exists in the played music files, play a music file with the highest audio quality in the at least one first music file.

The first music file and the music file to be played have the same music information, the audio quality of the first music file is higher than that of the music file to be played, and the music information at least comprises a song name.

Illustratively, continuing with the above example, if the music files stored in the storage space are as shown in table 1 above, when the music player determines that the music file to be played is the music file No. 03 according to the playing instruction, and the music player has previously played the music file No. 01 having the same music information as the music file No. 03. The playing unit 102 directly plays the music file No. 01 having higher audio quality after determining that the bit rate of the music file No. 01 is larger than that of the music file No. 03.

For another example, when the music player determines that the music file to be played is the music file No. 03 according to the playing instruction, and the music player has played the music file No. 01 and the music file No. 05 having the same music information as the music file No. 03 before, the music file No. 05 having the highest audio quality is directly played.

In the embodiment of the invention, when the same song with a plurality of versions with different audio quality is stored in the storage space, in order to achieve the effect that the music player can select the song with the version with the better tone quality to play each time, after the music file to be played is determined each time, the audio quality of the music file to be played is compared with the audio quality of the music file with the same music information played before, and if one or more music files with higher audio quality exist in the music files played before, the music file with the highest audio quality in the one or more music files with higher audio quality is directly played. The use experience of the user is improved.

In addition, the playing unit 102 is further configured to play the music file to be played if it is determined that the first music file does not exist in the played music files.

In the embodiment of the invention, when one or more music files with the same music information and better tone quality than the music file to be played exist in the played music files, the music file with the best tone quality is played; when the played music file does not have the music file with the same music information and the tone quality of the music file is better than that of the music file to be played, the music file to be played is played, and therefore when a user listens to music, the music file heard each time is the music file with the best tone quality in the played music files with the same music information. After all music in the storage space is read in a traversal mode, namely the played music files comprise the music files with the highest audio quality in the plurality of music files with the same music information in all the music files in the storage space, so that the played music files are the music files with the highest audio quality in the music files with the same music information in the storage space in each playing process, and user experience is improved.

It should be noted that, in the embodiment of the present invention, the music information may include one or more items of information such as an album title, a singer, and a music genre, in addition to the song title. For convenience of description, the music information in the following examples of the present invention includes four kinds of information, i.e., title, album, singer, and song type. In the specific implementation, those skilled in the art can select appropriate music information according to actual needs to make a judgment. The more information is included in the music information, the more accurately the music file belonging to the same song as the music file to be played can be found out. The invention is not limited thereto.

In addition, it should be noted that in the implementation of the present invention, different audio quality parameters may be selected to determine the audio quality of the music file. As shown in table 1, the audio quality is determined by using the bit rates of the music files, for example, the bit rates of the music file No. 01 and the music file No. 03 are 192Kbps and 128Kbps, respectively, which indicates that the audio quality of the music file No. 01 is higher than that of the music file No. 03. In addition, the compression format of the music file may also be used to determine the audio quality of the music file, for example, if the compression format of the a music file is WMA format and the compression format of the B music file is APE format, it may be determined that the audio quality of the B music file is higher. Those skilled in the art can select an appropriate audio quality parameter to determine the audio quality of the music file according to the requirement, and the invention is not limited thereto.

Specifically, in an embodiment, in order to enable the playing unit to determine whether at least one first music file exists in the played music files and play the music file with the highest audio quality in the at least one first music file after determining that at least one first music file exists, as shown in fig. 2, the playing unit 102 in the embodiment of the present invention specifically includes an inquiring subunit 1021, a comparing subunit 1022, and a playing subunit 1023, where:

the query subunit 1021 is configured to query, after the obtaining unit 101 obtains the playing instruction, a music file having the same music information as the music file to be played in the playing database, where the music file with the highest audio quality in at least one music file having the same music information in the played music files is recorded in the playing database.

For example, continuing to take the music files in the storage space shown in table 1 above as an example, assuming that the music files already played by the music player include music files No. 01, 02, 03, the music file to be played is determined to be music file No. 04 according to the playing instruction. It can be seen that the music information of the music file No. 01 is the same as that of the music file No. 03, and the bit rate of the music file No. 01 is higher than that of the music file No. 03. Therefore, at this time, the music file No. 01 and the music file No. 02, which are the music files having the highest audio quality among the music information, are recorded in the playing database, and the data recorded in the playing database are as shown in the following table 2:

TABLE 2

In the playback database, information relating to music file No. 01 is recorded in data No. 001, and information relating to music file No. 02 is recorded in data No. 002.

Further, the query subunit 1021 queries the No. 02 music file recorded in the No. 002 data by querying the playback database for a music file having the same music information as the No. 04 music file.

In addition, in one embodiment, music files having the same music information as the music file to be played and the highest audio quality are obtained for convenience. The embodiment of the invention also comprises the following steps:

the playing database is used for recording the music file with the highest audio quality in at least one music file which corresponds to each played music file and has the same music information with each played music file.

Illustratively, continuing with the example of music files in the storage space shown in table 1 above, assume that music files already played by the music player include music files No. 01 to No. 03. As can be seen from table 1, among the music files No. 01 to 03, the music files having the music information "aaa, ee, abc, f" include the music file No. 01 and the music file No. 03, and the audio quality of the music file No. 01 is higher; the music files having music information "bbb, gg, bcd, J" include music file No. 02. Then, at this time, the data recorded in the play database is as shown in table 3 below:

TABLE 3

The data 001 in the playing database records the music file with the highest audio quality in the music files with the same music information as the music file in the played music files corresponding to the music file 01, namely the data 001 records the music file 01; the data No. 002 records the music file with the highest audio quality among the music files with the same music information as the played music files corresponding to the music file No. 02, that is, the data No. 002 records the music file No. 02; data No. 003 has recorded the music file with the highest audio quality among the music files having the same music information among the music files played corresponding to music file No. 03, that is, data No. 003 has recorded music file No. 01. When the music file to be played is determined to be the music file No. 01 next time, the music file No. 01 can be determined to be played at the moment by inquiring any one of the data No. 001 or the data No. 003 in the playing database; when the music file to be played is determined to be the music file No. 03, the music file No. 01 to be played at the moment can be determined by inquiring the playing database.

In this way, the playing database records both the music file with the highest audio quality among at least one of the played music files having the same music information (for example, data No. 001 and data No. 003 in table 3 above all store the same music file with the highest audio quality among the music files having the music information "aaa, ee, abc, f", so if the music file with the highest audio quality among the music files having the music information "aaa, ee, abc, f" needs to be inquired, data No. 001 or data No. 003 needs to be acquired arbitrarily), and simultaneously records the music file with the highest audio quality corresponding to each music file in turn in the playing database, so that when a certain music file is taken as the music file to be played again later, the music file with the highest audio quality corresponding to the music file recorded in the playing database is directly played, a music file to be played is determined.

In addition, in an embodiment, the embodiment of the present invention further includes: and numbering each recorded music file in a playing database, wherein the numbering is used for determining the storage position of the music file corresponding to the numbering in the storage space.

In the embodiment of the invention, by numbering each music file in the playing database, the position of the music file recorded in the playing database in the storage space can be determined according to the number, and the process of searching the music file in the storage space is simplified.

A comparing subunit 1022, configured to compare the audio quality of the music file queried in the playing database by the querying subunit 1021 with the music file to be played.

Continuing with the above example, after the number 02 music information having the same music information as the number 04 music file is searched in the playback database, the bit rates of the number 04 music file and the number 02 music file are compared. Specifically, it can be seen that the bit rate of the No. 02 music file is 320Kbps, and the bit rate of the No. 04 music file is 128Kbps, thereby determining that the bit rate of the No. 02 music file is greater, i.e., determining that the audio quality of the No. 02 music file is higher.

The playing sub-unit 1023 is used for playing the music files inquired in the playing database after the comparing sub-unit 1022 determines that the audio quality of the music files inquired in the playing database is higher than the audio quality of the music files to be played.

Continuing with the above example, after determining that the audio quality of the No. 02 music file is higher than that of the No. 04 music file, it may be determined that the No. 02 music file and the No. 04 music file have the same music information and that the audio quality of the No. 02 music file is higher than that of the No. 04 music file, that is, the No. 02 music file is the first music file, and then the No. 02 music file is played.

In the embodiment of the invention, a playing database is established, and the music file with the highest audio quality in at least one music file with the same music information in the played music files is recorded in the playing database. And then, through the corresponding functions of the inquiry subunit, the comparison subunit and the playing subunit, the playing unit can play the music file with the highest audio quality in the at least one first music file when determining that the played music file has at least one first music file.

In another embodiment, it is considered that when music is played, it may occur that none of the played music files has the same music information as the music file to be played, or that none of the played music files has the same music information as the music file to be played. For example, it is assumed in this example that the music information includes a song name and a singer, and if the current music file to be played is a song named "sweet honey", the singer is a song named "dunlijun", and the bit rate is "320 Kbps", the song named "sweet honey" does not appear in the played music file, and the singer is a song named "dunlijun", or the played music file is a song named "sweet honey", and the singer is a song of "dunlijun", but the bit rate of the music file is "128 Kbps". Furthermore, the embodiment of the present invention further includes:

in one embodiment, when the playing unit 102 determines whether at least one of the played music files is at least one first music file through the querying sub-unit 1021, the comparing sub-unit 1022 and the playing sub-unit 1023, and if it is determined that at least one of the played music files exists, the music file with the highest audio quality in the at least one first music file is played, the playing unit 102 plays the music file to be played when determining that the first music file does not exist in the played music files. In the embodiment of the invention:

the playing sub-unit 1023 is further configured to play the music file to be played after the querying sub-unit 1021 determines that there is no music file in the playing database having the same music information as the music file to be played, or after the comparing sub-unit 1022 determines that the audio quality of the music file queried in the playing database is lower than or the same as the audio quality of the music file to be played.

Specifically, after the playing sub-unit 1023 plays the music files to be played, the music file with the highest audio quality in the same music information as the music files to be played recorded in the playing database is updated to the music file to be played, so that the music file with the highest audio quality in at least one music file with the same music information in the played music files is always recorded in the playing database.

In one embodiment, as shown in fig. 1, the music player further includes: a data update unit 103, wherein:

and a data updating unit 103, configured to update the playing database according to the music file played by the playing subunit.
