Abstract
The utility model relates to a language room teaching device for a bilingual class, which comprises a speech broadcasting end, a speech control end, and a connecting end used for connecting speech terminals and the speech control end. The speech control end consists of a shell body and a control circuit arranged in the shell body; the control circuit is formed by at least two switches connected in parallel; one end of each switch is led out of the shell body by a lead wire and is connected with the connecting end; and the other ends of the switches share the same lead wire and are connected with a microphone positive electrode wire at a microphone jack position of the speech broadcasting end; and a microphone negative electrode wire is led out from the microphone jack position and is also connected with the connecting end, so as to from a microphone loop. A headset positive electrode wire and a headset negative electrode wire are led out from a headset jack of the speech broadcasting end so as to form a headset closed loop. The speech terminals connected with one another in parallel are connected behind the connecting end in series. The language room teaching device has a simple structure and low cost, the line distribution is convenient and quick, and the device is suitable for popularization and application. When the language room teaching device is used in teaching, the teaching of a teacher and the answering of students can be clearly communicated, and the other students can also listen to the teaching synchronously.
Description
Technical field
The utility model relates to a kind of voice interface device, relates in particular to a kind of bilingual class language chamber instructional device.
Background technology
School is when language teachings such as English, Japanese, dimension language, Chinese, in order to make uninteresting language learning easier by digestion, absorption, usually this type of teaching is to give lessons in the voice classroom, though the interaction between the academics and students can be realized in existing voice classroom, and the interaction between student and the student, but it is very loaded down with trivial details that its circuit is laid, and lay the both expensive in a voice classroom, and therefore general country school can't create the voice classroom.
Summary of the invention
It is low that the purpose of this utility model is to propose a kind of cost, bilingual class language chamber instructional device simple in structure.
The purpose of this utility model is achieved in that bilingual class language chamber instructional device comprises a speech play end and a voice control end, and in order to connect the link of voice terminal and voice control end.Described speech play end can adopt voice playing device such as the loudspeaker that has earphone and microphone jack, sound-track engraving apparatus, language repeater, mp3 of market purchasing now.Described voice control end is by housing, and is installed in the control circuit composition in the housing, and control circuit is made up of the switch parallel with one another of n 〉=2, and an end lead of each switch leads to outside the housing, and this end is connected with link; Switch is held shared same lead in addition, and the microphone electrode line of drawing with speech play end microphone jack place links to each other.Draw a microphone negative line again at this microphone jack place, also be connected, constitute the microphone loop with link.In the earphone jack of speech play end, draw the positive and negative polar curve of earphone, constitute the earphone closed-loop path.Each link is connected with described switch, is in parallel between each link, is in series with voice terminal parallel with one another behind the link.
The utility model is simple in structure, and circuit is laid convenient, fast, and cost is lower, is fit to apply.When it uses in teaching, can with teacher say that clear contact is carried out in answering of student, and other students also can listen synchronously and separate, and language learning is very helpful.
Description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is a bilingual class language chamber instructional device circuit diagram;
Fig. 2 is the circuit diagram of phonetic controller.
Legend: 1, speech play end, 2, the voice control end, 3, voice terminal, 4, link.
Embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, bilingual class language chamber instructional device comprises a speech play end 1 and a voice control end 2, and in order to connect the link 4 of voice terminal 3 and voice control end 2.Described speech play end 1 can adopt voice playing device such as the loudspeaker that has earphone and microphone jack, sound-track engraving apparatus, language repeater, mp3 of market purchasing now.Described voice control end 2 is by housing, and is installed in the control circuit composition in the housing, and control circuit is made up of the switch parallel with one another of n 〉=2, and an end lead of each switch leads to outside the housing, and this end is connected with link 4; Switch is held shared same lead in addition, and the microphone electrode line of drawing with speech play end 1 microphone jack place links to each other.Draw a microphone negative line again at this microphone jack place, also be connected, constitute the microphone loop with link 4.In the earphone jack of speech play end 1, draw the positive and negative polar curve of earphone, constitute the earphone closed-loop path.Each link 4 is connected with described switch, and 4 of each links are in parallel, are in series with voice terminal parallel with one another 3 behind the link 4.
Be parallel with microphone on the microphone loop of 1 at voice control end 3 and speech play end, this microphone is to use for teacher.Be parallel with earphone on the earphone closed-loop path in speech play end 1, this earphone also is to use for teacher.
The corresponding link 4 of desk, voice terminal 3 is fixed on the desk, can install 1-3 voice terminals that do not wait 3 on every desk, voice terminal 3 and number of switches equity.
Described switch is installed in case surface, and with corresponding voice terminal corresponding characters.
Each link 4 comprises positive limit of microphone and microphone negative pole point, and an earphone tie point.The positive limit of described microphone is corresponding with voice terminal 3 numbers on being installed in desk.All positive limit of microphone is drawn the outer lead of housing with an aforementioned switch and is connected on each link 4, and microphone negative pole point links to each other with the microphone negative line of being drawn by speech play end 1 microphone jack.The earphone tie point then is connected with the earphone closed-loop path.
