Just, a lot of teachers associations select to be used wireless microphone as teaching aid, and teachers association needs PPT is entered according to explanation progress simultaneously
Row page turn over operation, can carry out page turn over operation using Pen for turning page to PPT more than current teacher, but during the hand-held translation pen of teacher, also can
Hand-held textbook or other teaching aids, hand-held Pen for turning page is very inconvenient, and wireless microphone more adopt tie clip wireless microphone it is not necessary to
Hand-held, and the emitter of tie clip wireless microphone is identical with the radiofrequency launcher principle of Pen for turning page, and the sound equipment of wireless microphone is many
It is placed on dais, if Pen for turning page is attached on wireless microphone, it will well solve Pen for turning page and take and use
Problem, and Pen for turning page functional realiey cost can be reduced.
Utility model content
The technical problems to be solved in the utility model is for not enough above, provides a kind of wireless with page turning distant control function
Microphone, makes wireless microphone have page turning distant control function, facilitates teacher to use, and reduces Pen for turning page functional realiey cost simultaneously.
For solving above technical problem, this utility model employs the following technical solutions：
A kind of wireless microphone with page turning distant control function, including main frame, wireless microphone；
Described wireless microphone includes microphone, emitter and page turning controller, and described microphone, page turning controller pass through to lead respectively
Line connects emitter, and described wire is located in same thread casing and page turning controller is located in the middle of microphone and emitter, described
The page turning signal of the audio signal of microphone and page turning controller is converted into radiofrequency signal by emitter；
Described main frame includes wireless receiver, rechargable power supplies, microphone, first switch and Micro USB slot, described
Wireless receiver, microphone, rechargable power supplies and first switch form current loop, described wireless receiver also with Micro
USB slot connects, and described Micro USB slot is connected with computer by USB data line, and described wireless receiver receives emitter
The radiofrequency signal of transmitting is simultaneously converted into audio signal and page turning signal, and described audio signal is transmitted directly to microphone and plays, institute
State page turning signal and be transferred to computer execution PPT page turn over operation via USB data line.
The following is the optimization further to such scheme：
It is provided with tie clip, described microphone is fixed on clothes by tie clip on described microphone.
Described main frame also includes second switch, and described Micro USB slot, rechargable power supplies and second switch 12 form electricity
Flow back to road, when described second switch is connected, described rechargable power supplies can be charged by computer.
During use, the emitter of wireless microphone is tied up on waist, microphone is hung on collar, now button controller hangs
With, when needing page turning, the button that user handss can at any time on depresses button controller, when being not required to page turning, user
Both hands can do other things.
After this utility model adopts above technical scheme, compared with prior art, there is advantages below：
Page turning controller is arranged on wireless microphone and is suspended between microphone and emitter, has liberated the double of user
Handss, and page turning controller passes through the emitter of wireless microphone and the wireless receiver transmission page turning signal of main frame, saves page turning
Controller is individually equipped with the manufacturing cost of emitter and wireless receiver, and when carrying out page turn over operation using this wireless microphone,
Computer can also be charged for wireless microphone.
With reference to the accompanying drawings and examples this utility model is described in detail.
