Embodiment
With reference to the accompanying drawings, specify the preferred embodiment of the utility model.
Fig. 1 is the stereographic map that briefly shows the antenna dual-purpose camera model structure of an embodiment of the utility model.
As shown in the figure, the antenna dual-purpose camera model of an embodiment possesses: camera lens; Permanent magnet is incorporated into a side of above-mentioned camera lens; Coil is with above-mentioned permanent magnet installed adjacent, so that interlinkage flux; The 1st connector is to above-mentioned coil supplies drive signals, so that above-mentioned camera lens moves; The 2nd connector, interval through at least a portion of above-mentioned coil, insert the RF signal.
As shown in Figure 1, antenna dual-purpose camera model 100 comprises camera lens 110, permanent magnet 120, coil the 130, the 1st connector 140 and the 2nd connector 150.
In a side of lens barrel 111, for example, be equipped with permanent magnet 120 in the lower end.Permanent magnet 120 is in a side of camera lens 110, with lens barrel 111 integrally formed, outfits.This permanent magnet 120 after under the magneticaction that takes place of the coil stated 130, camera lens 110 is moved up and down, thus the focus of alignment image, or control optical zoom (Optiacal zooming).In addition, on shell, fixing the bobbin 132 that supplies coil 130 to reel.
The 1st connector 140 is adjacent with permanent magnet 120, so that interlinkage flux, to the coil of between permanent magnet 120 and imageing sensor 131, installing 130 supply drive currents.So the magnetic flux that coil 130 takes place is when the magnet with permanent magnet 120 links, permanent magnet 120 moves, and passes through the fixedly focal length of all-in-one-piece camera lens 110 of lens barrel 111 thereby regulate.
The 2nd connector 150 is interval through at least a portion of coil 130, inserts RF (Radio Frequency) signal, gets into the state of activation that electric wave can launched or receive to coil 130.This 2nd connector 150 is provided on the shell of antenna dual-purpose camera model 100 of communication facilities, be used for being coupled through RF terminal non-contact capacitance with the outside receive, the transmitting RF signal.Explanation to this non-contact capacitance coupling will be narrated in the back.
Fig. 2 is installed on mobile device with the utility model antenna dual-purpose camera model 100, and the situation that for example is installed on mobile communication terminal is an example, is used to explain the block diagram of its action.
On the coil 130 of bobbin 132, form a plurality of electric terminals.In the present embodiment, coil 130 provides with pattern coil 130 forms of on printed circuit board (PCB), printing.Therefore, bobbin 132 becomes the dielectric plate that forms pattern coil 130 substrates.Use double layer substrate,, thereby form the RF contact K1 about 3 with joint configuration in substrate at the back, with regard to printed circuit board (PCB) 160, this is simple operation.Each RF contact K1 is through the terminal input of RF K switch 2.The contactless contact K3 that the RF K switch 2 output terminals face in the enclosure of being connected in is set up.
Through the switching of suitable control RF K switch 2, can control the direct conductor length that influences the antenna tuned frequency substantively.The control of this RF K switch 2 can be embodied by the person of ordinary skill in the field, therefore no longer specifies.As stated, the length of RF K switch 2 control conductors, thus can utilize an antenna to embody a plurality of tuning characteristics, support a plurality of frequency bands.At this moment, the path from each RF contact K1 to contactless contact K3, particularly, the length of drawing lead (feeder) that forms with pattern on the unshowned in the drawings dielectric plate should design fine.
When drawing the RF signal through not shown flexible printed circuit board; Even shelving the Electromagnetic Interference problem does not talk; Because the flexible printed circuit board of each portable equipment is with diversified length and form manufacturing usually; Thereby can't accurately design the RF path, exist each module needs to design the problem of radio characteristics one by one again.To this, because the shell of camera model 100 has standardized size substantially, therefore, carry out capacitive coupling through paster on the wall within it, thereby can make the RF characteristic keep constant.Moreover, can also cut off the direct current composition that flows into drive coil 130, realize only extracting the electric filter of RF signal simultaneously.
The utility model is not limited to previous embodiment, in the scope that can allow at the technological thought of the utility model, carries out multiple application or distortion use.
Though the utility model illustrates and explains with regard to specific embodiment; But the those skilled in the art can be readily appreciated that: not breaking away from the limiting of the utility model thought of claims statements and field, can carry out multiple transformation and variation.
