Abstract
The utility model relates to a supersonic wave wireless shutter of a cell phone, and is aimed at providing a cell phone shutter which is easy and convenient to use, is low in cost and has a one-to-many function. The supersonic wave wireless shutter comprises a main control single-chip microcomputer which includes a timer. The main control single-chip microcomputer is connected with a crystal oscillator, an LED lamp, a shooting button and a secondary supersonic wave emission sensor. When the shooting button is pressed, the main control single-chip microcomputer simultaneously controls the LED lamp to be switched on and controls the timer to produce secondary supersonic wave signals which are then transmitted to the secondary supersonic wave emission sensor.
Description
Technical field
The utility model relates to mobile phone photograph shooting field, is specifically related to the wireless shutter of a kind of ultrasonic handpiece.
Background technology
Mobile phone has been people's first camera at present, and people use the demand of mobile phone photograph more and more also more frequent.Remote control mobile phone is taken pictures on the market at present, is mainly by bluetooth or infrared etc.Infrared need to be divided into two, carries inconvenience, uses loaded down with trivial details.The mode of bluetooth is that bluetooth connects and pairing, cumbersome, causes user to experience bad.This threshold also causes a lot of people cannot use bluetooth shutter to carry out remote control shooting.In addition, the mode of bluetooth is man-to-man substantially, and inconvenience is controlled plurality of mobile phones simultaneously and taken pictures simultaneously.
Utility model content
It is simple that the technical problems to be solved in the utility model is to provide a kind of use, with low cost, can one-to-many use, the mobile phone shutter of aspect.
For reaching above-mentioned purpose, a kind of ultrasonic handpiece of the utility model is wireless shutter, it is characterized in that: comprise master control single-chip microcomputer, on described master control single-chip microcomputer, comprise timer, described master control single-chip microcomputer is connected with crystal oscillator, LED lamp, the button of taking pictures, inferior ultrasonic wave emission sensor;
When the button of taking pictures is pressed, master control single-chip microcomputer is controlled the bright and described timer of described LED lamp simultaneously and is produced time ultrasonic signal, and the inferior ultrasonic signal of generation passes to ultrasonic wave emission sensor described time.
The wherein said button of taking pictures replaces with camera switching key.
Wherein said master control single-chip microcomputer is connected with camera switching key.
On wherein said master control single-chip microcomputer, also comprise time ultrasonic wave amplification control circuit, between described master control single-chip microcomputer and described ultrasonic wave emission sensor, be provided with time ultrasonic amplifier, described ultrasonic wave amplification control circuit controlled and started described ultrasonic amplifier.。
Shutter difference from prior art that a kind of ultrasonic handpiece of the utility model is wireless is that the utility model obtained following technique effect:
1, the wireless shutter cost of manufacture of the utility model ultrasonic handpiece is cheap, uses simple;
2, every mobile phone that corresponding application programs is installed, uses the utility model ultrasonic wireless mobile phone shutter to control and to take pictures with a remote controller;
3, the wireless shutter of the utility model ultrasonic handpiece can be realized and control plurality of mobile phones simultaneously and take pictures.
Accompanying drawing explanation
Fig. 1 is the wireless shutter principle framework of ultrasonic handpiece figure;
Fig. 2 is mobile phone terminal application work principle framework figure.
Embodiment
Below in conjunction with drawings and Examples, to the utility model is above-mentioned, be described in more detail with other technical characterictic and advantage.
As shown in Figure 1, the utility model ultrasonic handpiece is wireless shutter, comprise master control single-chip microcomputer, on described master control single-chip microcomputer, comprise timer and time ultrasonic wave and control amplifying circuit, described master control single-chip microcomputer is connected with crystal oscillator, LED lamp, take pictures button and camera switching key, inferior amplitude of ultrasonic amplifier; Described time ultrasonic wave is controlled the unlatching that amplifying circuit is controlled described amplitude of ultrasonic amplifier, and described time amplitude of ultrasonic amplifier connects time ultrasonic wave emission sensor.
The initial condition that powers on, single-chip microcomputer place what super low-power consumption pattern, crystal oscillator failure of oscillation, inferior ultrasonic amplifier is closed, and waits for that take pictures button or camera switching key press always;
As depicted in figs. 1 and 2, when the button of taking pictures is pressed, monolithic exits super low-power consumption pattern, crystal oscillator starting of oscillation, LED lamp lights, single-chip microcomputer timer internal generation 4KHz and 16KHz+15.7KHz ultrasonic wave pwm signal are exported to time super twt amplifier simultaneously, the pwm signal of frequency one 4KHz+ frequency two 16KHz+ frequency three 15.7KHz amounts to 580 milliseconds of durations, when pwm signal arrives inferior ultrasonic amplifier, amplification control circuit is opened time ultrasonic amplifier, through PWM ultrasonic signal after amplification by inferior ultrasonic sensor by inferior synthesis in the air, after this LED extinguishes, crystal oscillator failure of oscillation, the large device of inferior ultrasonic wave also closes, single-chip microcomputer enters super low-power consumption pattern, if mobile phone has been opened corresponding application program when the transmitting of inferior ultrasonic wave, the microphone by mobile phone receives this ultrasonic wave, and a photo, the object of taking pictures to reach remote control mobile phone camera are taken in mobile phone camera response.
As depicted in figs. 1 and 2, when camera switching key is pressed, monolithic exits super low-power consumption pattern, crystal oscillator starting of oscillation, LED lights, simultaneously single-chip microcomputer timer internal produces 4KHz and 16.7KHz+15.7KHz ultrasonic wave pwm signal exported to inferior super twt amplifier, and the pwm signal of frequency one 4KHz+ frequency two 16.7KHz+ frequency three 15.7KHz amounts to 640 milliseconds of durations, by inferior hyperacoustic frequency and the different differentiations of the duration button of taking pictures; When pwm signal arrives inferior ultrasonic amplifier, amplification control circuit is opened time ultrasonic amplifier, through PWM ultrasonic signal after amplification by inferior ultrasonic sensor by inferior synthesis in the air, after this LED extinguishes, crystal oscillator failure of oscillation, the large device of inferior ultrasonic wave also closes, and single-chip microcomputer enters super low-power consumption pattern; If mobile phone has been opened corresponding application program when inferior ultrasonic wave transmitting, microphone by mobile phone receives this ultrasonic wave, mobile phone work at present camera is switched to post-positioned pick-up head or is switched to front-facing camera by post-positioned pick-up head by front-facing camera, the object of switching to reach remote control mobile phone front camera and rear camera.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection range of the utility model claims.
