Description
Technical field
This utility model relates to electronic instruction apparatus technical field, particularly one and gives lessons laser bar.
Background technology
Laser bar is the instrument that existing multimedia teaching is indispensable, but, existing laser bar is only intended to laser positioning, it does not simply fail to store data, and interaction cannot be formed with user after school, so due to the function singleness of laser bar, it is impossible to the storage realizing teacher's data is carried and diverts oneself.
Summary of the invention
In view of this, the purpose of this utility model is to provide one to give lessons laser bar, possesses telescopic USB interface.
This utility model uses below scheme to realize: one is given lessons laser bar, including column laser barred body, it is characterized in that: the laser head opposite end of described column laser barred body is provided with USB interface, it is fixedly installed a sleeve in the middle part of described USB interface end, described sleeve is set on a reciprocating screw rod, described reciprocating screw rod, by a step motor drive, moves back and forth on reciprocating screw rod in order to described sleeve；Circuit board and the battery powered for this circuit board it is additionally provided with in described column laser bar body；Described circuit board includes that a MCU, described MCU connection has laser generation module, step motor drive module, memory module, wireless communication module and key circuit；Described USB interface is connected with described MCU.
In this utility model one embodiment, described MCU is also associated with LED color lamp drive circuit, and described LED color lamp drive circuit is embedded at the LED color lamp on the external wall of laser bar of giving lessons for driving.
In this utility model one embodiment, described MCU is also associated with audio drive circuitry, and described audio drive circuitry is arranged at the loudspeaker in described column laser bar body for driving.
In this utility model one embodiment, described wireless communication module is bluetooth module.
This utility model simple in construction, not only has a laser positioning function, and can store teaching data and USB stretches.

Detailed description of the invention
For features described above of the present utility model and advantage can be become apparent, special embodiment below, and coordinate accompanying drawing, it is described in detail below.
Refer to Fig. 1, Fig. 2 and Fig. 3, the present embodiment provides one to give lessons laser bar, including column laser barred body 1, laser head 2 opposite end of described column laser barred body is provided with USB interface 3, it is fixedly installed a sleeve 4 in the middle part of described USB interface 3 end, described sleeve is set on a reciprocating screw rod 5, and described reciprocating screw rod 5 is driven by a motor 6, moves back and forth on reciprocating screw rod in order to described sleeve 4；So, USB interface just can be elastic under the drive of reciprocating screw rod；Circuit board 7 and the battery 8 powered for this circuit board it is additionally provided with in described column laser barred body 1；Described circuit board includes that a MCU, described MCU connection has laser generation module, step motor drive module, memory module, wireless communication module and key circuit.It will be clear that laser generation module includes laser lamp drive circuit, laser lamp and corresponding assembly, owing to these have been prior aries, the most no longer it is described in detail.Described USB interface is connected with described MCU.
In order to allow those skilled in the art understand benefit and the advantage of this utility model hardware configuration, illustrate below in conjunction with software, it is worth mentioning at this point that, this software is intended merely to further illustrate this utility model hardware configuration, and it is not required for protection；Rely on this utility model hardware configuration, described wireless communication module receives the audio signal of handheld terminal, the audio signal of reception is converted into the driving signal of motor by described MCU according to the height of audio signal, realizes, in order to the retracted position controlling USB interface when this laser bar of giving lessons stands on desktop, laser bar dancing of giving lessons.In order to avoid laser bar dancing process is toppled over, it is provided that a bracing frame, this bracing frame includes a base 9, the pole 10 that is arranged on base and be arranged on pole end for limiting and help the spacing ring 11 of laser bar of giving lessons.
In this utility model one embodiment, described MCU is also associated with LED color lamp drive circuit.When combining software, described MCU drives the LED color lamp being embedded at described column laser bar surface to work (in figure, the position of LED color lamp is not illustrated) according to the height of the audio signal received through LED color lamp drive circuit.Lighting effects are integrated into and give lessons in laser barred body, change with retracted position, effect that is interactive and that dance can be improved.
In this utility model one embodiment, described MCU is also associated with audio drive circuitry, and described MCU is played out by the loudspeaker being arranged in described column laser bar body through audio drive circuitry while controlling described USB interface retracted position according to audio signal.Being arranged by these loudspeaker, this laser bar of giving lessons can be danced by the audio file being stored in memorizer, accomplishes that music is play on jumping limit, limit.
In this utility model one embodiment, the control instruction that described bass, middle pitch are corresponding with high pitch is all to rotate forward；The control instruction that described middle bass is corresponding with alt is all reversion.Owing to using step motor control, its number of turns rotated can be accurately controlled, it is ensured that the telescopic effect of USB interface.
In this utility model one embodiment, this handheld terminal can be mobile phone.Described wireless communication module is bluetooth module.
The foregoing is only preferred embodiment of the present utility model, all impartial changes done according to this utility model claim and modification, all should belong to covering scope of the present utility model.
