Although in addition, present electronic teacher pointer can as common chalk on projection screen cross, write,
In practical applications, many teacher's feedbacks, it is old although electronic teacher pointer can use the content on laser alignment projection screen
Teacher using electronic teacher pointer when, hand shaking or hand slightly shake, be directed toward curtain on laser point also be easy shake, cause laser point from
Pointed content is opened, therefore this electronic teacher pointer often will appear deviations, to influence teaching efficiency, disperse student's
Attention.And traditional long-rod type teacher's pointer, then be not in the inaccurate problem of positioning.
Utility model content
The utility model proposes a kind of electronic teacher pointer capable of recording, electronic teacher pointer has sound-recording function, facilitates teacher by class
Hall content recordal gets off, and student is facilitated to collect the classroom recording of teacher, and recording effect is good, is conducive to promote effect of giving lessons；With biography
System teacher's pointer is combined, and simple in structure, easy to use, accurate positioning is easy to carry.
What the technical solution of the utility model was realized in：
One kind can record electronic teacher pointer, including transmitter and receiver, and transmitter includes launcher shell, microcontroller control
Device, button, coding unit, RF rf transmitter units, loud speaker, microphone, amplification filter unit and AD conversion unit；AD conversion
Unit, loud speaker, button and coding unit are connect with singlechip controller respectively, and RF rf transmitter units connect with coding unit
It connects；Microphone is connect with amplification filter unit, and amplification filter unit is connect with AD conversion unit；Launcher shell threaded one end connects
It is connected to Telescopic pointer.
Further technical solution, receiver include receiver control unit, decoding unit and RF rf receiver units, are connect
It receives device control unit to connect with decoding unit, RF radio frequency receiving units are connect with decoding unit.
Further technical solution, transmitter are equipped with USB interface.
The utility model has the beneficial effects that：The utility model be equipped with transmitter and receiver, transmitter built-in microphone,
And it is equipped with storage unit, sound-recording function, and the storage of recording are realized, facilitates teacher during giving lessons by said knowledge
Recording is got off, and recording is clear, and recording effect is good, is conducive to the classroom recording that student collects teacher, is reviewed in classroom for student
Appearance provides a convenient；Launcher shell threaded one end is connected with Telescopic pointer, when teacher needs to carry out using traditional teacher's pointer
When teaching, Telescopic pointer in connection, so as to more accurately be positioned to the content on projection screen or blackboard.
The utility model is simple in structure, easy to use, light-weight, small, and accurate positioning is easy to carry.
