Abstract
A portable audio player, selecting songs with shortcut keys, includes a keyboard (1), a control processor (2), a display screen (3), an audio player (4), and a song memorizer (5). The display screen (3) can display a plurality of song names at the same time. The keyboard (1) is provided with a plurality of song-selection keys (8), which are corresponding with each song name of the display screen (3). A song-selection key (8) is pressed to input signals into the control processor (2), which calculates out the storage position of the song audio data of the song name on the display screen (3). The control processor (2) transmits the song audio data to the audio player (4) for playing. The display screen can display a group of songs for users to select. For examples, eight songs name can be displayed at the same time. Page-up and page-down keys on the keyboard can be used to upgrade the current group of songs, and songs can be selected through pressing a song-selection key from (1) to (8). The operation is simple and convenient; all operations can be completed manually, which provide great convenience for users; with broad application prospect, the invention can be used on traffic tools, station reporter of public transport, single-sentence English player, family acoustics, etc.
Description
1, technical field:
The present invention relates to a kind of portable audio player with shortcut key for selecting music.
2, background technology:
At present, portable audio player major product type has MP3, MP4, and discman etc., main selected songs mode is a bent selected songs mode up and down.The defective of this melody selecting method is:
● if the song that carrier stores is more, needs the long time of cost navigate to want the song of listening;
● the part portable audio player must cooperate ability complete operation, troublesome poeration by both hands;
● the general first song title that only shows simultaneously of display, select for the user, relatively more dull.
3, summary of the invention:
The purpose of this invention is to provide a kind of portable audio player with shortcut key for selecting music, its selected songs is quick, and is easy to operate.
The present invention is achieved by the following technical solution:
A kind of portable audio player with shortcut key for selecting music, comprise keyboard, the control and treatment part, display screen, voice playing part and song memory, display screen can show some first song title simultaneously, keyboard is provided with some selected songs buttons, the every first song title of the corresponding display screen of these selected songs buttons, push a selected songs button signal is input to the control and treatment part, partly calculate song voice data memory location to the song title on should the display screen of selected songs button by control and treatment, the control and treatment part is delivered to voice playing with this song voice data and is partly play.
Above-mentioned described keyboard is provided with page turning key and following page turning key, and last page turning key and following page turning key can upgrade the song title that is presented at the some head of display screen.
Above-mentioned described some selected songs buttons are meant more than 3 or 3, and some first song title are meant that 3 is first or more than 3 head.
Above-mentioned described control and treatment part mainly comprises single-chip microprocessor MCU.
Above-mentioned described song voice data memory location obtains as follows: A) song of song memory is pressed the number of songs M grouping paging that once shows simultaneously on the display screen, and write down current page number X; B) push a selected songs button, receive the serial number N that this selected songs button triggers; C) calculate the data storage location=M*X+N that selects song.
The output terminal of above-mentioned described control and treatment part also is connected with wireless transmitter module.
The present invention compared with prior art has following advantage: 1) can show that a suite order is for user's selection by every screen on display screen, for example can show 8 first song title simultaneously, on keyboard, use page turning key, down page turning key can page turning upgrades a suite order of current demonstration, directly press the selected songs button, 1 to 8 selected songs button for example, just can select song, simple and quick convenience realizes quick selected songs function; 2) all operations can be finished by one-handed performance, and the user is more convenient to use; 3) the present invention has application prospect in the following aspects, because they all require to locate song or sentence fast, usable range is wide, for example vehicles voice playing; Public transport is called out the stops; Simple sentence English player, home audio etc.; 4) can send the song voice data by wireless transmitter module 9, use convenient.
4, description of drawings:
Below in conjunction with accompanying drawing the present invention is done detailed explanation:
Fig. 1 is a surface structure synoptic diagram of the present invention;
Fig. 2 is a circuit block diagram of the present invention;
Fig. 3 is the program control flow chart of control and treatment part of the present invention the inside.
5, embodiment:
As Fig. 1, shown in Figure 2, the present invention includes keyboard 1, control and treatment part 2, display screen 3, voice playing part 4 and song memory 5, display screen 3 can show some first song title simultaneously, keyboard 1 is provided with some selected songs buttons 8, these selected songs button 8 corresponding display screen 3 every first song title, push a selected songs button 8 signal is input to control and treatment part 2, calculate song voice data memory location to the song title on should the display screen 3 of selected songs button by control and treatment part 2, control and treatment part 2 is delivered to voice playing part 4 with this song voice data and is play.Keyboard 1 is provided with page turning key 6 and following page turning key 7, and last page turning key 6 and following page turning key 7 can upgrade the song title that is presented at display screen 3 some head.Some selected songs buttons are meant more than 3 or 3, and some first song title are meant that 3 is first or more than 3 head.Control and treatment part 2 mainly comprises single-chip microprocessor MCU.Above-mentioned described song voice data memory location obtains as follows: A) song of song memory 5 is pressed the number of songs M grouping paging that once shows simultaneously on the display screen 3, and write down current page number X; B) push a selected songs button 8, receive the sequence number N that this selected songs button triggers; C) calculate the data storage location=M*X+N that selects song.The output terminal of control and treatment part 2 also is connected with wireless transmitter module 9, can send the song voice data by wireless transmitter module 9, and wireless transmitter module 9 can be based on the wireless transmitter module of radio FM channel.
As shown in Figure 3, the program control flow chart of control and treatment part of the present invention the inside is as follows: suppose song memory 5 sequential storage 200 first songs, display screen 3 once can show 8 first songs, obtaining total page number is 25 pages, 8 selected songs buttons 8 are arranged on the keyboard 1, the digital 1-8 table of these selected songs button 8 usefulness is known serial number, tactic 8 first songs on the corresponding display screen 3, in the control program of control and treatment part 2 the insides, with 200 first songs of song memory 5 storage in order, by per 8 first song one component component pages or leaves, and write down current page number X, the serial number of supposing the selected songs button 8 that the user presses is N, the storage location of selected song is 8X+N, when by last page turning key 6 or page turning key 7 down, the X value of current record is added one or subtract one and get final product.Therefore, the search song is very quick.
