Fig. 1 is the synoptic diagram of the utility model preferred embodiment.
Fig. 2 is the synoptic diagram of the utility model preferred embodiment.
Fig. 3 is the fundamental diagram of the utility model preferred embodiment.
Embodiment
To combine accompanying drawing and embodiment that the utility model is described further below:
As depicted in figs. 1 and 2; A kind of multimedia CD-MP3 language learner; Comprise shell (1), in the enclosure circuit main board, loudspeaker (2), microphone (3) are installed, be provided with the CD player core in the shell, the CD player core is installed in the CD box (4); Shell is provided with LCD display (5) and function button (6), and the side of shell is provided with the USB socket.The embodiment of the utility model adopts the higher fire-resistant ABS material of safety coefficient as machine shell, and appearance design has taken into full account the dual needs that meet student's study and audio-visual education room; The Electrical Appliances Designing aspect adopts the software and hardware combining mode, uses up-to-date chip development corresponding function, and PCB designs and uses double-decker, and succinct reliable, complete machine also has man-machine friendly operation interface, and large-scale LCD shows, reasonable panel operation layout.Many Interface design demonstrate fully the principal feature that learns a language.
As shown in Figure 3, said circuit main board is provided with master chip (7), SDRAM buffer (8), note amplifier (9), CD driver (10), LCD/ and presses key drive (11); SDRAM buffer (8) is connected with master chip (7); The input end of note amplifier (9) is connected with master chip (7), and output terminal is connected with loudspeaker (2), earphone socket respectively; One end of CD driver (10) is connected with master chip (7), and the other end is connected with the CD player core; The end that LCD/ presses key drive (11) is connected with master chip (7), and the other end is connected with LCD display, button respectively.
As shown in Figure 3; Said master chip (7) comprises processor controls, demoder, USB processor, digital to analog converter, FLASH processor, SRAM processor, phaselocked loop; Processor controls is connected with demoder, phaselocked loop, and demoder is connected with USB processor, digital to analog converter, SRAM processor, FLASH processor.
The utility model also is provided with the SD deck, and the SD deck is connected to master chip (7) through data line.
CD has two kinds of form settings.CD box (4) is a top-opening type, and lid is arranged on upper surface of outer cover, and the CD player core is installed in the lid below.CD box (4) is laterally opened, and the CD player core is installed in the CD box, and CD player core and CD box eject from a side of shell in the lump during unlatching.
The utility model can common MP3 dish SD obtain media information on the relevant carriers such as card, pass through the processing and the exchange of data then, accomplish the learning machine function.
The course of work is following: energising back CD player core from CD or USB interface from U the dish relevant carriers obtain speech data, through the master chip decoding and be temporarily stored in the SD RAM buffer,, realize the different disposal mode of data through the operation of keyboard.Relevant speech data is the digital processing mode, and sound effect is more clear than conventional tape drives, storage time is more permanent, obtains advantages such as the approach of data is more extensive.Speech play: through the control button operation, master chip from medium MP3 extract speech data CD or the USB flash disk, after inner decoding, be transported to note amplifier reduction audio frequency, carry out speech play; Re-reading: through the control button operation; Will from MP3 the speech data that extracts CD or the USB flash disk; In single TRACK file, realize that the voice of the arbitrary number of times of A-B time period repeat, therebetween the speed of scalable voice, more accurately provide convenience for learning a language; With reading contrast: through the control button operation, will from MP3 the speech data that extracts CD or the USB flash disk, in single TRACK file; The at first selected learning pronunciation paragraph that needs, selected after through inter-process, it is buffered in the storer SD RAM, after selected voice paragraph finishes; Recorded voice appears; The learner says the learning pronunciation content according to the time of former sound, is buffered in the storer SD RAM, behind the End of Tape through language data process and with it; Automatically play former sound, admission voice, realize comparing function; The word speed regulatory function: play the random time of voice, through the control button operation, from CD extract speech data CD or the USB flash disk and handle through master chip, paragraph can be realized five grades of speed arbitrarily, for soon, comparatively fast, normally, slow, slow.
The demand that the utility model learns a language according to the student; In conjunction with the characteristics-speech play of traditional magnetic tape type learning machine, re-reading, with read contrast, word speed is regulated; Developed especially can MP3 realized the learning functionality of conventional tape drives on the multimedia CD of carrier, and promoted the relevant multiple more flexibly function of learning a language.Through research and creation, aspect product operation, realized the hommization operation interface, easy and simple to handle, flexible.Product not only has the basic function of general learning machine, and also developing of innovation recorded the courseware that the student learns a language, and has improved teacher greatly students'language is learnt the supervisory of practical extent; The language of this machine is play and is recorded and carried out software processes, and sound is clear, accurate.Filled up a blank field of learning machine field update stage.Product function is powerful, simple to operate, has cost advantage, and extension product is abundant, has the vast market application space.
