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 a kind of laser head extension type to give lessons laser bar, including column laser barred body 1, described column laser barred body is provided with laser head 2 that can be elastic, the end of described laser head 2 is provided with a sleeve 4, 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, laser head 2 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 are connected with described laser head through laser drive circuit, and described MCU is also associated with step motor drive module, memory module, wireless communication module and key circuit.
In order to allow those skilled in the art be better understood from effect and the effect of this utility model structure; it is described further below in conjunction with existing software; to describe herein; this software is the application do not claim; in the present embodiment; described wireless communication module can be used for receiving 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 laser head 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, the both sides of described laser head have lead 3, described lead can in the gathering sill 12 of described column laser barred body front end shell slide anteroposterior, i.e. laser head elastic under the drive of reciprocating screw rod.
In this utility model one embodiment, described MCU is also associated with LED color lamp drive circuit, and 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 laser head 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 described height according to audio signal is converted into the implementation driving signal of motor and is: audio signal is divided into five regions, is bass, middle bass, middle pitch, alt and high pitch respectively；Each region each corresponding a kind of control instruction.This utility model is not limited thereto system, this implementation can also have multiple, using subregion to control in the present embodiment is owing to the frequency range of music is about at 20Hz---20KHz, by the restriction of scope, whole range can be converted into simple several control instruction, not only design conveniently, and the change of state is more apparent.
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 laser head.
In this utility model one embodiment, this handheld terminal can be mobile phone.
In this utility model one embodiment, 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.
