Description
[technical field]
The utility model relates to a kind of recording device, particularly a kind of digital audio format input recording processor that is applicable to the voice classroom.
[background technology]
The voice classroom is a study auxiliary equipment the most commonly used in the present In-class language teaching, propagates audio-frequency information by wired or wireless mode between the Faculty and Students.For the ease of reviewing after class, the student often notes telling about of teacher by sound pick-up outfits such as recording pens, because noise jamming etc. can not reach the effect in the anticipation, how the sound signal that intercepting needs among the network of voice classroom becomes new problem.
[summary of the invention]
Technical assignment of the present utility model is at above the deficiencies in the prior art, and a kind of digital audio format input recording processor that is applicable to the voice classroom is provided.
The technical scheme in the invention for solving the technical problem is: a kind of digital audio format input recording processor, comprise audio frequency input block and audio recording unit, it is characterized in that: described audio frequency input block comprises audio input interface and the signal processor that Audio Data Line, circuit link to each other; Described audio recording unit comprises single-chip microcomputer, function button, storer, the battery that circuit links to each other; Function button, single-chip microcomputer, storer link to each other with control line in proper order by data line, address wire; Described signal processor links to each other with single-chip microcomputer by data line.
Also comprise display unit, comprise display screen, display control circuit, single-chip microcomputer links to each other with display control circuit with control line by data line.
Above-mentioned storer comprises two storeies, and audio memory is used for the speech data of store compressed, the code book of code book memory stores speech recognition and speech processes program.
Above-mentioned audio memory is the mini-SD card.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, freely intercept the audio frequency that needs, convenient and practical;
2, integrated level height, cost is low, and volume is little, and is in light weight;
3, can be integrated on the student's machine of voice classroom, the mini-SD card that the last machine transplanting of rice of each student is gone into oneself gets final product.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
[embodiment]
Below in conjunction with specification drawings and specific embodiments the utility model is further specified.
As shown in Figure 1, the utility model embodiment comprises audio frequency input block, audio recording unit, display unit.It consists of:
Described audio frequency input block comprises audio input interface and the signal processor DSP (ADSP-218X) that Audio Data Line, circuit link to each other.
Described audio recording unit comprises single-chip microcomputer Micro Control Unit NICU (KS57C0400), function button, storer, the battery that circuit links to each other; Function button, single-chip microcomputer, storer link to each other with control line in proper order by data line, address wire; Described signal processor links to each other with single-chip microcomputer by data line.Described storer comprises two storeies, and audio memory is used for the speech data of store compressed, the code book of code book memory stores speech recognition and speech processes program.Described audio memory is the mini-SD card.
Described display unit comprises LCD display, display control circuit, and single-chip microcomputer links to each other with display control circuit with control line by data line.
The mode that the utility model inserts voice classroom network can be two kinds, and during the utility model independence one, Audio Data Line is with voice classroom audio output interface and audio frequency input block audio input interface UNICOM.In addition, the utility model also can be integrated into student's board face, keeps display unit, function button, audio memory socket on the surface.
The sound signal in voice classroom is undertaken entering the audio recording unit after amplification filtering is handled by Audio Data Line entering signal processor.Function button transfers to single-chip microcomputer with the different electric signal of " recording " " time-out " " affirmation " " cancellation ", the single-chip microcomputer encoding process, and to audio memory, relevant information exports on the display screen LCD with the control audio information storage.In addition, the code book of code book memory stores speech recognition and speech processes program are used to carry out speech recognition.
Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
