Traditional electronic teacher pointer can be realized the effect of laser designation, as patent No. ZL03251003.9, discloses a kind of electronic teacher pointer, can realize the laser tracking; Other can be regulated the volume, brightness etc. of multimedia presentation system in explanation by manual overvide, as ZL200420014950.1.Above-mentioned teacher's pointer is used to refer to the explanation position and regulates the brightness of explanation content or the operations such as volume of sounding.

But all there are some defects in these electronic teacher pointers of tradition, show as following deficiency:

1. function singleness, relatively simple for structure, although can use, the defect of function has been not enough to various functions.

2. can only realize deixis, to the explanation content carry out other operations, the speaker must be operated by computer, and the speaker is limited in around computer, if go in auditoria with everybody, exchange just very inconvenient.

3. operating process is loaded down with trivial details, the separate device switching manipulation, complex redundancy.

4. in the face of new multimedia operations the time, various types of operations have been not enough to, such as the page turning of PPT, displaying video animation etc.

The utility model provides a kind of electronic teacher pointer with USB interface, comprise a plurality of signal buttons and the function selecting key that arrange on main body and main body, wherein, the signal controlling key is arranged on the upper area of main body, function selecting key is arranged on the central region of main body, lower area in main body is provided with frequency key and power key, be provided with signal projector and signal receiver on the top of main body, body interior is provided with main control module, circuit module, to frequency module and power module, lower end in main body is provided with USB interface, between USB interface and main control module, by power module, be connected.

Preferably, above-mentioned signal controlling key comprises and AV signal switch key, master control key are set, receive key and emission key.

Preferably, the above-mentioned functions options button comprises multifunction key, directionkeys and acknowledgement key.

Preferably, above-mentioned main control module is connected with circuit module, described frequency module is connected with main control module by circuit module respectively with power module.

Preferably, be provided with the signal condition pilot lamp between above-mentioned AV signal switch key and reception key.

Preferably, be disposed with connection state pilot lamp and power state pilot lamp under above-mentioned signal condition pilot lamp.

Preferably, also be provided with the first online indication LED and the second online indication LED in aforementioned body, the described first online indication LED is connected with main control module by circuit module respectively with the second online indication LED.

The electronic teacher pointer with USB interface that the utility model provides is compared with traditional electronic teacher pointer, by the USB interface that is arranged on bottom, electronic teacher pointer and digital product can be coupled together, realize the exchange of data or utilize USB interface to be charged, very easy to use.
