In the invention, a user inquires the information relevant to the music only according to the music fragments and is not required to set the conformity between the music beat and note information of the fragments and the music beat and note information in a database to control the searched hit rate and searching precision, thereby being convenient for users to operate and improving the working efficiency without repeated operation.
Description
Technical field
The present invention relates to the telecommunications field, relate in particular to a kind of method and mobile phone thereof that utilizes the handset processes music fragment to obtain song information.
Background technology
Along with the development of mechanics of communication, the function of mobile phone from strength to strength, music phone and to utilize mobile phone to visit the Internet or other networks also more and more general.We hear one section pleasing to the ear song through regular meeting, but do not know name, singer or other the relevant information of this song.Usually, if, be difficult to directly search on the internet and confirm the relevant information of this section music only according to the melody of one section music.
China national Department of Intellectual Property discloses a kind of method for searching music based on musical segment information inquest on July 23rd, 2008, and publication number is CN 101226526A.This method bag is:: the music beat and the note information that A) analyze any fragment in the music of confirming or song convert behind the digital quantity foundation as this music of search or song into; B) music beat of this music or the arbitrary fragment of song and the index of note information are arranged in the database; C) need inquire about as according to the search comparison, can search required music or song.Only the invention has the advantages that and just can carry out music searching, greatly expanded the degree of freedom of music retrieval, made things convenient for the requirement of user, realized searching for generally of music music retrieval through a music rhythm or snatch of song; Searching for when comparison, the music beat in the music beat that fragment can be set and note information and the index database and the degree size that conforms to of note information data are with raising search hit rate or raising search precision.
Though said method also can be realized the method retrieved according to snatch of music; But the hit rate of its retrieval and retrieval precision are to control by the music beat in music beat that fragment is set and note information and the index database and the degree size that conforms to of note information data; The described degree that conforms to is excessive; The result for retrieval that possibly occur is too much, and the user needs audition one by one to get rid of; The said degree that conforms to is too small, might cause omission again, and this is not easy to operate for the user, often need manually repeat repeatedly, just might find the information of wanting.
Summary of the invention
The invention provides a kind of method and mobile phone thereof that utilizes the handset processes music fragment to obtain song information.
This method comprises a kind of method of utilizing the handset processes music fragment to obtain song information, comprises successively: step 1) is used to obtain the step of snatch of music; Step 2) is used for snatch of music is handled the also step of query-related information; The step of step 3) output Query Result.
