Description
Technical field
The present invention relates to intelligent television and interactive mode teaching field, particularly a kind of tutoring system based on televisor.
Background technology
Teacher, when carrying out classroom instruction, in order to ensure quality of instruction, makes all students on classroom can catch the content of teacher's instruction, generally need to improve volume, if teacher lectures loudly always, the throat of teacher easily goes wrong again, is unfavorable for that teacher's is healthy.At present, in a lot of classroom, all televisor is installed, how utilizes televisor better to transmit the content of courses, do not affecting the throat effectively protecting teacher under the prerequisite that student normally listens to the teacher, become in current interactive mode teaching the problem needing to solve.
Summary of the invention
[technical matters that will solve]
The object of this invention is to provide a kind of tutoring system based on televisor, to solve current classroom teaching teacher by the excessive problem of throat.
[technical scheme]
The present invention is achieved by the following technical solutions.
The present invention relates to a kind of tutoring system based on televisor, it comprises wireless MIC and televisor, described televisor comprises less radio-frequency receiver module, audio conversion module, power amplifier and loudspeaker, described less radio-frequency receiver module and wireless MIC communicate to connect, described audio conversion module is connected with less radio-frequency receiver module and power amplifier respectively, described power amplifier is connected with loudspeaker, described wireless MIC is for sending the less radio-frequency receiver module of sound signal to televisor, described less radio-frequency receiver module is for receiving the sound signal of wireless MIC transmission and this signal being sent to audio conversion module, described audio conversion module is used for converting the sound signal received to simulating signal and being sent to power amplifier.
As one preferred embodiment, described wireless MIC is provided with the switch opened and closed for controlling wireless MIC.
As another preferred embodiment, described tutoring system also comprises telepilot, described telepilot comprises the first control button and second and controls button, described first controls button for controlling the opening and closing of less radio-frequency receiver module, and described second controls button for regulating the size of tv volume.
As another preferred embodiment, described wireless MIC and televisor pass through twireless radio-frequency communication.
Below principle of work of the present invention is described.
The sound signal that user sends by wireless MIC is sent to the less radio-frequency receiver module of televisor, after the less radio-frequency receiver module of televisor receives sound signal, by this audio signal transmission to audio converter; Sound signal is converted to simulating signal by audio converter, then is transferred to power amplifier; Power amplifier processes the simulated audio signal received, amplifies, and is finally transferred to loudspeaker, the demand that completing user amplifies.
[beneficial effect]
The technical scheme that the present invention proposes has following beneficial effect:
(1) the present invention makes teacher can move flexibly in teaching process, because this enhancing the interaction between teacher and student, effectively improves quality of instruction, greatly facilitates teacher's teaching.
(2) adopt tutoring system provided by the present invention, teacher can use less volume to impart knowledge to students, and therefore solves teacher and uses throat overscale problems at classroom teaching.
Accompanying drawing explanation
The structural representation of the tutoring system based on televisor that Fig. 1 provides for embodiments of the invention.
Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, clear, complete description is carried out to the specific embodiment of the present invention, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiment, neither limitation of the present invention.Based on embodiments of the invention, those of ordinary skill in the art, not paying the every other embodiment obtained under creative work prerequisite, belong to protection scope of the present invention.
The structural representation of the tutoring system based on televisor that Fig. 1 provides for the embodiment of the present invention.As shown in Figure 1, it comprises wireless MIC1 and televisor 2, wireless MIC1 and televisor 2 realize radio communication by Wi-Fi, wherein wireless MIC1 is provided with the switch opened and closed for controlling wireless MIC1, televisor 2 comprises less radio-frequency receiver module 21, audio conversion module 22, power amplifier 23 and loudspeaker 24, less radio-frequency receiver module 21 and wireless MIC1 communicate to connect, audio conversion module 22 is connected with less radio-frequency receiver module 21 and power amplifier 23 respectively, and power amplifier 23 is connected with loudspeaker 24.
In the present embodiment, wireless MIC1 is for sending the less radio-frequency receiver module 21 of sound signal to televisor 2, less radio-frequency receiver module 21 is for receiving the sound signal of wireless MIC1 transmission and this signal being sent to audio conversion module 22, audio conversion module 22 is for converting the sound signal received to simulating signal and being sent to power amplifier 23, power amplifier 23 is for amplifying the simulating signal received and the signal after amplifying being sent to loudspeaker 24, and loudspeaker 24 convert the simulating signal received to acoustical signal.
In the present embodiment, tutoring system also comprises telepilot, wherein telepilot comprises the first control button and the second control button, and first controls button for controlling the opening and closing of less radio-frequency receiver module 21, and second controls button for regulating the size of televisor 2 volume.
Below the principle of work of the present embodiment is described.
The sound signal that user sends by wireless MIC1 is sent to the less radio-frequency receiver module 21 of televisor 2, after the less radio-frequency receiver module 21 of televisor 2 receives sound signal, by this audio signal transmission to audio converter 22; Sound signal is converted to simulating signal by audio converter 22, then is transferred to power amplifier 23; Power amplifier 23 processes the simulated audio signal received, amplifies, and is finally transferred to loudspeaker 24, the demand that completing user amplifies.
