Abstract
The utility model relates to an electronic pointer, in particular to a laser pointer device with an independent microphone, comprising a laser pointer device. The laser pointer device comprises a pointer casing, a laser, a laser switch, a displacement sensor, a rechargeable battery, a microprocessor and a wireless transmitter, wherein a voice input interface is installed at the tail part of the pointer casing; the laser pointer device also comprises a voice output interface, the independent digital microphone, a data cable and a wire collector. According to the laser point device, when the voice output interface and the voice input interface are in butt joint, the voice signal from the independent digital microphone can be inputted to the laser pointer through the data cable, the microprocessor of the laser pointer can control the wireless transmitter to transmit the voice signal, people can still use the laser pointer when giving voice lecturing, the contradiction of the laser pointer function and the microphone function is eliminated, the wire collector also can be used for collecting data cables, multiple functions are integrated, lecturers are enabled to realize wandering-type multimedia operation, and the convenience is brought for use.
Description
Technical field
The utility model relates to a kind of electronic teacher pointer, especially a kind of laser pointer device with independent microphone.
Background technology
Along with the development of computing machine and periphery technology thereof, multi-media classroom, meeting room are come into each teaching, training unit and each company gradually.Present multimedia presentation chamber all is furnished with computer, projector.In speech or explanation process; The speaker often need carry out the operation of travelling type to the explanation content, for example with the volume of teacher's pointer indication explanation position, the brightness of regulating the explanation content or sounding, the explanation content is carried out scroll-up/down, page turning, utilized computer to operations such as the emphasis of explanation indicate.The at present existing electronic teacher pointer that microphone is housed because its microphone is fixed on the teacher's pointer housing, its in use laser indication operation can not carry out simultaneously with wireless microphone explanation operation, use inconvenience.
The utility model content
The utility model provides a kind of laser pointer device with independent microphone, and its laser pointer device and microphone can use simultaneously, uses easily.
Realize that the technical scheme that the utility model purpose is adopted is: a kind of laser pointer device with independent microphone; It comprises the laser pointer device; The laser pointer device comprises teacher's pointer housing, laser instrument, laser switch, displacement transducer, rechargeable battery, microprocessor, wireless launcher, it is characterized in that: teacher's pointer housing afterbody also is equipped with a speech input interface; It also comprises a voice output interface, an independent digit microphone, a data line, a spooler, and the independent digit microphone is connected through data line with the voice output interface, and spooler is installed on the data line.
The utlity model has following beneficial effect: when the voice output interface docks with speech input interface; Voice signal on the independent digit microphone can input to the laser pointer device through data line; The microprocessor of laser pointer device can be controlled wireless launcher voice signal is sent, and the people still can use the laser pointer device when carrying out speech sound eeplaining, cancellation the contradiction of laser pointer device function and microphone phonetic function; Its spooler can collect data line; Multifunctional all can let the speaker realize the multimedia operations of travelling type, and is very easy to use.
