Description
Technical field
The present invention relates to the Web-based instruction, and in particular to the special microphones used in a kind of Web-based instruction.
Background technology
Remote teaching, it is called and does electronic instruction, be a kind of learning aid system of formalization, it is to be led to by using electronics
Conveniently section performs distance learning and specially designed.Remote teaching is not expensive and do not fettered by geographic factor, it
The place being had any problem to carry out traditional education provides the chance of teaching.Because more high resilience is simultaneously in time for long-distance education
And can transmit anywhere, so it can be those can not receive traditional education due to routing or distance problem
The raw chance that study is provided such as employee.Remote teaching has many different forms, and correspondence, television teaching, distance teaching are all
Belong to the category of remote teaching, these teaching methods have many good qualities, than if sufficiently allowing more people using educational resource
Receive an education.Our described remote teaching herein are to utilize communication, network, multimedia, computer equipment and technology now, gram
The novel remote teaching pattern for taking the limitation of traditional Remote teaching and being formed.Modernizing remote teaching needs complete teaching system
System supports that the system has three links or control environment, and main broadcaster room is the teaching environment of teacher, for gathering education informations；Far
Journey classroom is the environment of Students ' Learning, receives education informations, feedback student information；Both are controlled by computer network at information.
In remote teaching, microphone is essential hardware device, but current microphone microphone after height is adjusted
It can not keep in the center, also need manual operation microphone is returned height originally, so as to bring corresponding inconvenience for teaching.
The content of the invention
Present invention aims at solve current microphone after height adjust microphone can not automatic returning it is in situ, also need artificially
Operation makes microphone return height originally, so as to bring the problem of corresponding inconvenient for teaching.It is in view of the above-mentioned problems, of the invention
The special microphones used in a kind of Web-based instruction are provided, its is simple in construction, easy to use, can improve microphone height, microphone at any time
After being loosed one's grip in certain altitude microphone can automatic rebounding to former height.
The purpose of the present invention is achieved through the following technical solutions：
A kind of special microphones used in Web-based instruction, including signal wire, main strut and microphone, the signal wire and microphone point
It is not connected with the both ends of main strut, includes the pole socket of cone barrel, the main strut is inserted in pole socket；
The part of the main strut insertion pole socket has been hinged at least three struts, the non-articulated of the strut
Place is connected with main strut side by retractor device；
The retractor device includes the sleeve of motion bar, spring and single radial cut, and the motion bar is stretched into sleeve, the work
One end in lever insertion sleeve is connected by the bosom of spring and sleeve, and the sleeve is hinged with strut, the motion bar
It is hinged with main strut, in the course of the work, the spring is in compressive state all the time.
When main strut is inserted in pole socket, the spring in retractor device is in compressive state all the time, when needing microphone
During raising, main strut is gradually lifted up, the strut being hinged during this with main strut is inwardly tightened up, therefore the compression of spring
Degree gradually increases, and the outside elastic force of spring also gradually increases；When needing to playback in microphone, microphone only need to be decontroled, is now pressed
The spring of contracting ejects motion bar to outside sleeve, so as to cause strut outwards to deploy, because strut and pole socket inner surface connect
Touch, therefore support force direction of the pole socket inner surface to strut free end is obliquely, because spring begins in the course of the work
Compressive state is in eventually, therefore the bottom playback of main strut can be arrived lowest part by the support force.
Further, the motion bar stretches into the side of the part of sleeve and is provided with limited block, and motion bar can be prevented by bullet
Go out sleeve.
Further, the free end of the strut is provided with roller, in the course of the work, strut not with table in pole socket
Face is contacted, and roller contacts with pole socket inner surface all the time, and pole socket inner surface can be made only to be carried out by pair of rollers strut
The effect of power, main strut can be made more smooth in the process kept in the center.
Further, the pole socket forms cone barrel by least two covering of the fans, passes through fixed plate between the covering of the fan
Fixed, the side of the pole socket is provided with string holes, and the signal wire stretches out pole socket from string holes, in storage, transport and dimension
When repairing internals of the present invention, pole socket can be split into two covering of the fans, string holes is used to draw the connected signal wire of main strut.
Further, in addition at least one secondary pole, the secondary pole are hinged with main strut, multiple secondary poles according to
Secondary be hinged, the free end of secondary pole is connected with microphone described in final section, can be improved the flexibility ratio of the present invention, can be made microphone
Farther place is extended, main strut and secondary pole is formed specific angle to adapt to specific use environment.
By using the present invention, following beneficial effect can be produced：The present invention includes signal wire, main strut, microphone, pole
Socket, strut and retractor device, strut are hinged with main strut, and the both ends of retractor device are hinged with strut and main strut respectively, are stretched
Spring in compression apparatus is in compressive state all the time, and retractor device, which outwards supports strut, causes branch rod bearing inner surface to strut
All the time obliquely, in use, main strut can recoil to original height, it is necessary to when overhauling the present invention to power at any time, will can bore
The pole socket of tubular is split into multiple covering of the fans.
