Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1.Modular structure schematic diagram for multimedia playing apparatus in an embodiment of the present invention 100.Multimedia playing apparatus 100 comprises input block 10, storage unit 20, main control unit 30 and display unit 40.
In the present embodiment, input block 10 is a pressure type touch-screen, and user is by the input of knocking to realize music rhythm to input block 10.Input block 10 responds knocking of user and produces corresponding induced signal.Main control unit 30 receives the induced signal that input block 10 produces, and the dynamics of user being knocked on input block 10 according to this induced signal, the number of times knocking, knock the residence time of finger on touch-screen and the time interval between adjacent twice hammer action at every turn and analyze, user is converted into music rhythm data to knocking of touch-screen.In other modes, input block 10 can be also piezoelectric type touch pad, resistive touch device etc. other can detect user the dynamics of knocking, knock beginning other input equipments to the time interval between the time finishing and adjacent two hammer action.
The number of times of the induced signal that wherein, input block 10 produces is the number of times that user knocks on input block 10; User's the dynamics of knocking difference, the intensity of the induced signal that this input block 10 produces is different, knock the duration that the residence time of finger on touch-screen is one section of induced signal of input block 10 generations, the time interval between adjacent twice hammer action is the time interval of twice adjacent induced signal of input block 10 generations at every turn.Main control unit 30 is according to the number of times of this induced signal, the intensity of induced signal, the time interval of the duration of each induced signal and every adjacent twice induced signal determines respectively dynamics that user knocks on input block 10, the residence time of finger on touch-screen and the time interval between adjacent twice hammer action while knocking at every turn.
In storage unit 20, store a plurality of music files and a plurality of and described music file music rhythm file one to one.In the present embodiment, music file also can be stored in external memory storage 21, and a plurality of and described music file one to one music rhythm file is stored in storage unit 20.
A plurality of induced signals that input respond module 32 produces for receiving input block 10, and number of taps on input block 10 of the dynamics value of knocking on touch-screen according to a plurality of induced signals judgement users that receive, user, from knocking for the first time, start to knock information to knocking for the last time the time of end and the time interval adjacent two hammer action etc., and will described in the information of knocking be sent to rhythm analysis module 33.Wherein, when this input respond module 32 for example, does not receive induced signal in the schedule time (10 seconds) after receiving an induced signal, judge corresponding the knocking as knocking for the last time of this induced signal.
Concrete, rhythm analysis module 33 records are from knocking for the first time the tempo M starting to knocking for the last time the time T second of end and times N that user knocks and judge music rhythm, wherein M=N*60/T.
Cadence information (the tempo M of the music rhythm of user's input that rhythm contrast module 34 calculates rhythm analysis module 33, putting in order of the umber of beats of every trifle and every trifle strong beat weak beat) with music rhythm file in the cadence information of storing contrast, for example, if the music rhythm that the cadence information of music rhythm file is inputted with user is consistent or similarity surpasses a predetermined value (80 percent music rhythm is identical), be judged as qualified music rhythm file; If the similarity of the music rhythm of the cadence information of music rhythm file and user's input, lower than this predetermined value, is judged as ineligible music rhythm file.
Music file corresponding to the result output module 35 qualified music rhythm file of search, and this music file is shown on display unit 40.
Please refer to Fig. 2, the music file search method flow process in an embodiment of the present invention comprises the steps:
Step S1, input block 10 response users knocking input action and produce corresponding induced signal on touch-screen.
Step S2, the dynamics value that input respond module 32 is knocked on touch-screen according to this induced signal judgement user, starts to knocking for the last time the time of end and the time interval adjacent two hammer action from knocking for the first time.
Step S3, the dynamics value that rhythm analysis module 33 knocks on touch-screen according to user, determines that from knocking for the first time the time and the time interval adjacent two hammer action that start to knocking for the last time end user knocks the cadence information of input.
Concrete, rhythm analysis module 33 records are inputted the tempo M that the times N of knocking judges music rhythm, wherein M=N*60/T from knocking for the first time the time T and the user that start to knocking for the last time end.
Step S4, the user that rhythm contrast module 34 calculates rhythm analysis module 33 knocks the cadence information of storing in the cadence information of music rhythm of input and music rhythm file and contrasts, judge that the whether consistent or similarity of the music rhythm of the cadence information of music rhythm file and user's input is greater than a predetermined value, if, be judged as qualified music rhythm file, enter step S5; If not, be judged as ineligible music rhythm file, continue step S4.
Step S5, music file corresponding to the result output module 35 qualified music rhythm file of search, and this music file is presented on display unit 40.
User is forgetting or is not knowing song title, in the situation of the information such as singer, only need to remember part music rhythm and the rhythm of this song, just can be by knock input cadence information according to corresponding melody and rhythm on input block 10, multimedia playing apparatus 100 just can be searched qualified music file fast.
Those skilled in the art will be appreciated that; above embodiment is only for the present invention is described; and be not used as limitation of the invention; as long as within connotation scope of the present invention, within the appropriate change that above embodiment is done and variation all drop on the scope of protection of present invention.
