Description
Technical field
The utility model is related to teaching equipment technical field, more particularly to a kind of computor -based instruction apparatus for demonstrating.
Background technology
During computer teaching, by simple classroom instruction, it is difficult to allow student to grasp knowledge point deeply.With meter
Calculation machine aided education is increasingly popularized, and numerous teachers are one after another using the modernization such as computer, projecting apparatus, multimedia courseware
Educational aid carries out classroom instruction, teacher is trapped in more aobvious protrusion the drawbacks of teaching is implemented on computer side.Teacher will be
Frequently walked about between computer and dais so that the expression of teacher, limbs, language receive computer and greatly constrain, influenceed
Entirety is used, and according to infrared remote control equipment, generally only possesses the effect of page turning or instruction, there is larger control limitation.
Utility model content
The utility model solves above-mentioned deficiency, there is provided a kind of computor -based instruction apparatus for demonstrating, with design
Simply, cost it is relatively low, it is easy to use the characteristics of.
The technical problem that the utility model is solved can be realized using following technical scheme：
A kind of computor -based instruction apparatus for demonstrating, including PC and projector equipment, one is provided with the projector equipment
Phonetic controller, the phonetic controller includes speech chip, control module, loudspeaker and sound pick-up, the control mould
A single-chip microcomputer is provided with block, a period of time clock oscillating circuit is equipped with outside the single-chip microcomputer, the clock oscillation circuit is by crystal oscillator and two
Individual ceramic disc capacitor is constituted, and the single-chip microcomputer is connected with the speech chip, P1.4 pins and P1.2 pins point in the single-chip microcomputer
, so as to form communication connection, the speech chip is connected by exclusion not to connect EOM pins and PD pins in the speech chip
Power module, SP+ pins and SP- pins connect the loudspeaker in the speech chip, in the speech chip MIC pins and
MIC-REF pins connect the sound pick-up.
The speech chip uses ISD2590.
The single-chip microcomputer uses AT89S52.
The crystal oscillator frequency selects 11~24MHz.
The utility model by having the advantages that compared with prior art：The utility model passes through optimization design,
Improve projector equipment, using sound control structure, improve the performance of teaching demonstration, with design it is simple, cost is relatively low, use
The characteristics of facilitating.
The characteristics of the utility model, see the detailed description of this case schema and following preferable implementation method and obtain clear
Ground understands.
Brief description of the drawings
Fig. 1 is overall control structure schematic diagram of the present utility model；
Fig. 2 is phonetic controller electrical block diagram of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
As shown in Figure 1 to Figure 2, a kind of computor -based instruction apparatus for demonstrating that the utility model is provided, including PC 1
And projector equipment 2, a phonetic controller 3 is provided with projector equipment 2, phonetic controller 3 includes speech chip 6, control mould
Block 4, loudspeaker 7 and sound pick-up 5, speech chip 6 use ISD2590, the inner set of speech chip 6 memory cell, vibration
Device, sound pick-up preamplifier, automatic growth control, anti-aliasing filter, smoothing filter, speaker drive, with multistage
Language process function, with low-power consumption, tonequality true nature, using it is easy to connect the characteristics of, is provided with a monolithic in control module 4
Machine 8, single-chip microcomputer 8 to be used and be equipped with a period of time clock oscillating circuit 9 outside AT89S52, single-chip microcomputer 8, and clock oscillation circuit 9 is by crystal oscillator and two
Individual ceramic disc capacitor is constituted, and crystal oscillator frequency is needed close proximity to single-chip microcomputer from 11~24MHz, crystal oscillator and ceramic disc capacitor in connection
8, single-chip microcomputer 8 is connected with speech chip 6, and P1.4 pins and P1.2 pins connect EOM in speech chip 6 and draw respectively in single-chip microcomputer 8
, so as to form communication connection, speech chip 6 connects power module by exclusion for pin and PD pins, in speech chip 6 SP+ pins and
SP- pins connect loudspeaker 7, MIC pins and MIC-REF pins connection sound pick-up 5 in speech chip 6.
Utility model works principle is：When user says control command, sound pick-up 5 completes voice collecting, transmission
To speech chip 6, after speech chip 6 completes corresponding data Treatment Analysis, while loudspeaker 7 can be completed at voice dialogue
Reason, improves performance, and in output correspondence control communication data transfer to single-chip microcomputer 8, single-chip microcomputer 8 is completed to projector equipment 2
The further control of other parts, improves overall performance, so that the convenient regulation control completed to projector equipment 2.
The utility model improves projector equipment by optimization design, using sound control structure, improves the use of teaching demonstration
Performance, with design it is simple, cost is relatively low, it is easy to use the characteristics of.
As known by the technical knowledge, the utility model can be by other essence without departing from its spirit or the reality of essential feature
Scheme is applied to realize.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only
's.It is all in the range of the utility model or in the change being equal in the range of the utility model by the utility model bag
Contain.
