Abstract
A remote English teaching device mainly solves the problems that sound cannot transmit in a long distance in a large classroom and is characterized in that a wireless signal emitter consists of a casing, a first microprocessor and a wireless emitter, wherein the first microprocessor is disposed in the casing, a signal output end of the first microprocessor is connected with a signal input end of the wireless emitter, a touch plate and an emitting antenna are fixed outside the casing, a signal output end of the touch plate is connected with a signal input end of the first microprocessor, and a signal input end of the emitting antenna is connected with a signal output end of the wireless emitter. A wireless signal receiving amplifier consists of an upper casing, a lower casing and a built-in element. By the aid of the remote English teaching device, teachers can play various pre-recorded teaching contents through a loudspeaker disposed at a far end of a spacious classroom, and on one hand, the teachers can show body languages with voice contents, on the other hand, the teachers do not need to speak all the time and can teach in the large classroom when in sick.
Description
Technical field
The utility model relates to a kind of servicing unit that is used for English teaching.
Background technology
Along with the increased enrollment year by year of institution of higher learning, every English Instructor once gives lessons demand side, and right student's quantity increases by geometric progression, and teacher's the space of giving lessons is also just increasing gradually, has the classroom of a lot of schools to reach the area of hundreds of square metre.In this case, the English Instructor has to speak up in order to guarantee teaching quality at every turn, and a class gets off, and all is exhausted basically.In the prior art, solve this problem through be equipped with microphone to the teacher often, still, the teacher need hand microphone, has often limited performance, the especially English teaching of some body languages again, and body language is very important sometimes.In addition, a lot of teachers can feel under the weather when using microphone, are difficult to reach the boundary of free representation language.
Summary of the invention
In order to solve the prior art problem that proposes in the background technology; The utility model provides a kind of long-range English teaching device; Utilize the long-range English teaching device of this kind teacher to carry out when body language shows at needs; The various lecture contents of prerecording are come out through the loudspeaker plays that is placed on spacious classroom far-end, and the teacher can cooperate voice content performance body language so on the one hand, and the teacher can also reduce phonation volume on the other hand; Also can be in uncomfortable for the student give lessons in lyceum, very convenient and practical.
The technical scheme of the utility model is: the long-range English teaching device of this kind; Receiving enlarger two parts by wireless signal transmitter and wireless signal constitutes; Its unique distinction is: said wireless signal transmitter by housing, place No. 1 microprocessor, wireless launcher of housing to constitute, the signal output part of said No. 1 microprocessor is connected to the signal input part of said wireless launcher; At said housing external fixation touch pad and emitting antenna are arranged, the signal output part of said touch pad is connected to the signal input part of No. 1 microprocessor, and the signal input part of said emitting antenna is connected to the signal output part of said wireless launcher;
Said wireless signal receives enlarger and is made up of upper shell and lower house and built-in element; Wherein, connect through articulated manner between said upper shell and the lower house; Be distributed with microphone, button and LCDs on the said upper shell; No. 2 microprocessors and storer are arranged in the said upper shell; Said microphone and button are connected respectively to the respective signal input end of said No. 2 microprocessors, and the signal input part of said LCDs is connected to the audio-video signal output terminal of said No. 2 microprocessors; Doing bidirectional traffic between said No. 2 microprocessors and the said storer is connected; Said lower house is built-in with amplifier and loudspeaker; The audio signal input end of said amplifier is connected to the audio signal output end of said No. 2 microprocessors through cable, and the audio signal output end of said amplifier is connected to the audio signal input end of loudspeaker.
During practical implementation, said No. 1 microprocessor and No. 2 microprocessors are the MCS52 series monolithic.
The utlity model has following beneficial effect: the teacher before use; Can be stored in wireless signal to many contents of courses of prerecording through microphone and receive in the storer in the enlarger, and set the concrete zone of this section content on touch pad on the wireless signal transmitter.When using; The program that the teacher prestores in according to No. 1 microprocessor on hand-held wireless signal transmitter touch pad; Can select to want the content of reading flexibly; Above-mentioned signal is transmitted to wireless signal and receives the wireless receiver in the enlarger, under the control action of No. 2 microprocessors, the audio file of the store memory storage of correspondence is taken out the back send through loudspeaker.Utilize the long-range English teaching device of this kind; The teacher can be when needs carry out the body language displaying; The various lecture contents of prerecording are come out through the loudspeaker plays that is placed on spacious classroom far-end, and the teacher can cooperate voice content performance body language so on the one hand, and the teacher can also reduce phonation volume on the other hand; Also can be in uncomfortable for the student give lessons in lyceum, very convenient and practical.
