Description
Technical field
Electronic instruction equipment is the utility model is related to, more particularly to a kind of wireless audio-visual education programme microphone transmitters system.
Background technology
Existing wireless audio-visual education programme microphone on the market, typically only include common radio microphone function and teaching laser work(
Can, common audio-visual education programme microphone has the emitter of typical circular handheld transmitter, the emitter of hand-held centre of the palm formula and waist-mounted type, its
In, the emitter of typical circular hand-held（Usually no laser pen）, it is necessary to the moment takes and near opposite face
Spoken, such basic function that can just complete microphone.That another hand can only just take laser pen, so may result in
Teacher is in a rush.And need in addition purchase laser pen carry out audio-visual education programme, not easy care；The emitter of hand-held centre of the palm formula（Typically
There is laser pen）, it is necessary to the moment takes and nearby spoken against face, such base that can just complete microphone
This function.But it is not just properly to go to speak very much, because prior to laser function while laser pen is used；Waist-mounted type
Emitter can just complete the basic function of microphone, it is necessary to connect tie clip microphone or head microphone, and not have laser pen.By
Then microphone is connected on emitter, and line back and forth or can be got rid of to get rid of inconvenience.Also need to buy laser pen progress electricity in addition
Teach, not easy care.
Therefore existing wireless audio-visual education programme microphone has laser pen that easy care, laser function can not be compatible not complete with earphone function
It is beautiful, function is single, the shortcomings that other miscellaneous functions such as not playing.
