Embodiment Construction
[0025] see figure 1 Shown is a schematic diagram of the system structure of the present invention. The system structure includes: a driving motor 110 disposed on the mobile terminal 10 , a lens moving mechanism 120 , and a lens device 130 . When the mobile user uses the laser pointer, the key on the mobile terminal 10 activates the drive motor 110 to rotate, and then the drive motor 110 drives the lens moving mechanism 120 to work, and the lens device 130 for adjusting the laser pointer laser beam spot size is due to the lens moving mechanism 120 The driving effect of the laser beam starts to adjust the focal length of the laser beam, thereby adjusting the size of the laser beam spot.
[0026] The driving motor 110 may be a stepping motor.
[0027] Working mechanism of the present invention is as follows:
[0028] 1. When the mobile terminal phone is turned on, the software is initialized, and the stepping motor drives the lens moving mechanism to work to drive the lens dev...

The invention discloses a laser pen focus regulator and a mobile terminal with the regulator, applied to a mobile terminal with laser pen, and the regulator comprises: driving motor, lens moving mechanism, and lens device, where the driving motor is connected with the lens moving mechanism and drives the lens moving mechanism to operate; the lens moving mechanism is fixed with the lens device to drive the lens device to move away / close in the laser beam emitting direction of the laser pen so as to implement regulating facular size of laser beam. When the laser pen operates, a user activates on-phone software by keys to drive the whole focus regulator to operate so as to regulate position of the lens device, i.e. regulating focus of laser beam, and finally implementing regulating the facular size of the laser beam.
Description
technical field [0001] The invention relates to the field of mobile communication terminals, in particular to a device for adjusting the focal length of a laser pointer and a mobile terminal with the device. Background technique [0002] At present, many mobile phones are equipped with laser pointers. The biggest advantage of this kind of mobile phone with laser pointer is that it combines the laser pointer and mobile phone into one, which is especially suitable for business people to use in meetings, eliminating the need to carry mobile phones and The trouble of two things for the laser pointer; in particular, with this laser pointer, there is no need to buy button batteries and alkaline batteries separately, and the laser pointer is powered by the battery of the mobile phone, which not only saves money, but also is more environmentally friendly. [0003] However, the laser pointer is also a relatively dangerous electronic device. The red laser beam it emits has a very smal...
