Description
Technical field
This utility model is specifically related to a kind of slr camera shutter timer control device, belongs to slr camera technical field of external equipment。
Background technology
Slr camera shutter intervalometer (cable release), is the external equipment of slr camera, is for there being line traffic control slr camera to take pictures, and has timing function, it is possible to allows camera repeat in required time to take pictures。Existing camera shutter intervalometer is a micro controller system, and it includes master controller, tripper, liquid crystal display, and battery is powered, and it connects slr camera by a cable release。When using as common cable release, user's button of partly tripping carries out camera focusing, and push button shooting one photo completely。When using as shutter intervalometer, user sets the number of shooting photo, interval by arranging button, after the parameter such as time delay, can start timing and take pictures。There is parameter and arrange complexity in existing slr camera shutter intervalometer, operator scheme is single, the shortcoming that volume is inconvenient to carry greatly。
Utility model content
Therefore, the purpose of this utility model be to provide a kind of simple in construction, easy to carry, be easy to manipulation slr camera shutter timer control device, including intelligent mobile phone terminal, described slr camera shutter timer control device also includes earphone conversion head, described earphone conversion head includes plug and audio conversion circuit, described audio conversion circuit includes bootstrap circuit boost and filter circuit, the earphone jack of described plug correspondence intelligent mobile phone terminal, and described earphone conversion head connects slr camera。
Further, it is connected with each other by camera shutter connecting line between described earphone conversion head and slr camera。
Wherein, described camera shutter connecting line is connected by the jack being arranged on earphone conversion head with earphone conversion head, or earphone conversion head is fixedly installed on camera shutter connecting line one end。
The beneficial effects of the utility model are in that: a kind of slr camera shutter timer control device of the present utility model, extend audio frequency input function, audio signal is converted to the shutter signal controlling camera, user is facilitated to operate, earphone conversion head can be directly inserted in the earphone jack of intelligent mobile phone terminal, volume is little, easy to carry, utilize intelligent mobile phone terminal can also simplify shutter intervalometer structure and extension more use function。This utility model is suitable for various slr camera and uses as external equipment。
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of slr camera shutter timer control device of the present utility model；
Fig. 2 is the circuit diagram of audio conversion circuit。
Accompanying drawing labelling is as follows: 1, intelligent mobile phone terminal；2, earphone conversion head；3, plug；4, earphone jack。
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is illustrated:
As shown in Figure 1, a kind of slr camera shutter timer control device, including intelligent mobile phone terminal 1, intelligent mobile phone terminal 1 is connected with slr camera shutter intervalometer communication, slr camera shutter timer control device also includes earphone conversion head 2, earphone conversion head 2 includes plug 3 and audio conversion circuit, and audio conversion circuit includes bootstrap circuit boost and filter circuit, the earphone jack 4 of the corresponding intelligent mobile phone terminal of plug 3。
Earphone conversion head 2 can be plugged in 3.5 millimeters of earphone jacks 4 of intelligent mobile phone terminal, audio conversion circuit is as shown in Figure 2, including bootstrap circuit boost and filter circuit, bootstrap circuit boost utilizes Bootstrap diode, the electronic components such as Bootstrap electric capacity, make electric capacity discharge voltage and supply voltage superposition, so that voltage raises, bootstrap circuit boost lifting output voltage, solve the European Union area restricted problem to mobile phone max volume, without booster circuit, on the mobile phone of European Union area, owing to volume is too little, voltage is too low cannot be switched by turn-on transistor, and then slr camera cannot be triggered。Audio signal is changed into the shutter signal controlling camera after audio conversion circuit。
Preferably, it is connected with each other by camera shutter connecting line between earphone conversion head 2 and slr camera。
Wherein, camera shutter connecting line is connected by the jack being arranged on earphone conversion head 2 with earphone conversion head 2, and this mode goes for different brands camera。Or earphone conversion head 2 is fixedly installed on camera shutter connecting line one end, directly earphone conversion head 2 being customized to a upper plug of shutter connecting line, product form is a shutter connecting line customized, and such product is more succinct。
When needs are taken pictures, the audio frequency that a band frequency is 20000Hz is play by intelligent mobile phone terminal 1, this section audio is changed into the shutter signal controlling camera by audio control circuit, shutter timer control device is connected by shutter connecting line with slr camera, conducting focusing pole and public pole, camera will start focusing, the fast gate pole of conducting camera shutter release cable and public pole, camera will start to take pictures, shutter intervalometer is controlled by intelligent mobile phone terminal 1, the structure of shutter intervalometer can be simplified, it is also possible to according to prior art expanded function, such as motion triggers etc.。
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from principle described in the utility model; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model。
Claims (3)
