Description
technical field:
the utility model relates to a kind of English teaching device with sound-recording function.
background technology:
the English teaching of traditional university belongs to basic course, the form of large class is generally taked to impart knowledge to students, the Area comparison in classroom is large, student is also many, the student that English Instructor sits in the back row in the process of teaching often does not hear English Instructor and is saying what content, when English Instructor has said that class answers the problem of student's proposition, if English Instructor is also not easy not hear the problem that student puies forward when student sits in the back row, if when voice is large especially, the not only very tired study also affecting former row student of English Instructor, the English teaching of present stage also has and to adopt public address equipment, but effect neither be very desirable.
summary of the invention:
the purpose of this utility model is to provide a kind of English teaching device with sound-recording function.
above-mentioned object is realized by following technical scheme:
a kind of English teaching device with sound-recording function, its composition comprises: housing, in described housing, there is main circuit board, described main circuit board has reception/transmitter module, recording module and main control singlechip, described main circuit board periphery is also connected with power supply, USB interface and change-over switch, described USB interface and change-over switch are solid on housing, and described main circuit board also connects in earphone, microphone, and described reception/transmitter module has exterior antenna.
the English teaching device of described band sound-recording function, described main circuit board also has audio frequency amplification, frequency modulation mixing, modulation /demodulation, peripheral cell needed for filtering.
the English teaching device of described band sound-recording function, described main circuit board is also connected with display.
the beneficial effects of the utility model:
1. English teaching device of the present utility model, volume is little, and structure is simple, award words and radio reception quality high, there is advanced speech process and Anti-Jamming Technique, converse clear, sound is loud and clear, its advantage is that Faculty and Students can share (device is transmitting terminal, and another assembling is set to receiving end), in classroom instruction process, teacher utilizes this device to lecture to student, and student utilizes this device to receive and records, and USB interface can be utilized to shift file to recording in good time.
english teaching device of the present utility model, due to everyone a receiving end can be held, by the use of change-over switch, can either accomplish that the carrying out of one-to-many is explained, also man-to-man answering a question can be met, and when teacher answers a question to student one to one, the study of other students can not be had influence on.
english teaching device of the present utility model, due to everyone a receiving end can be held, how many students no matter are had to listen to the teacher, sound can both be sent in each student's ear by English Instructor accurately, student is helped not hear, understand every a word of English Instructor, say class hour English Instructor, also teaching device can have been taken away or with USB, teacher is said that content does unloading on classroom.
english teaching device of the present utility model, due to everyone a receiving end can be held, owing to adopting advanced modular technology, can ensure that effective long recording time of recording module reaches 7 ~ 8 hours, by the adjustment of frequency, the functions such as logical, group is logical, Qu Tong, broadcast, safety detection, activation can be realized.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present utility model.
