For example, D1, D2, and D3 may be 0.03 mm to 0.2 mm.

For example, a damping member (not shown) may be further disposed between the inner surface of the housing 140 and the outer peripheral surface of the bobbin 110.

Next, the second coil 170 will be described.

The second coil 170 is disposed on the outer surface of the housing 140.

For example, the second coil 170 may be disposed above the outer sides of the side portions 141 and 142 of the housing 140.

The second coil 170 may be a ring-shaped coiled to rotate clockwise or counterclockwise with respect to the optical axis. For example, the second coil 170 may have a ring shape that surrounds the outer sides of the first and second sides 141 and 142 of the housing 140 in the clockwise or counterclockwise direction with respect to the optical axis.

The second coil 170 may be positioned below the upper elastic member 150 and above the magnet 130.

The second coil 170 at the initial position of the AF moving part (for example, the bobbin 110) may not overlap with the magnet 130 in a direction perpendicular to the optical axis direction. This is to reduce the interference between the magnet 130 and the sensing coil 170.

The second coil 170 is positioned at a predetermined distance from the first coil 120 in the direction of the optical axis at an initial position of the AF moving part (for example, the bobbin 110) (Not shown). Maintaining a predetermined distance between the first coil 120 and the second coil 170 in the direction of the optical axis ensures the linearity of the induced voltage induced in the second coil 170 by the current of the first coil 120 It is for this reason.

In the initial position of the AF moving part, the second coil 170 may overlap with the magnet 130 in the optical axis direction, but the present invention is not limited thereto. In other embodiments, the second coil 170 may not overlap each other in the optical axis direction.

The second coil 170 may be disposed on the outer side of the side portions 141 and 42 of the housing 140 so that at least a portion of the second coil 170 is positioned outside the support member 220. For example, the outside of the support member 220 may be opposite the center of the opening of the housing 140 with respect to the support member 220.

The second coil 170 may be an induction coil for sensing the position or displacement of the AF moving part, for example, the bobbin 110. [ For example, the second coil 170 may be implemented in the form of wire, FPCB, or FP (Fine Pattern) coil.

For example, when the AF moving part moves due to the interaction between the first coil 120 provided with the driving signal and the magnet 130, an induced voltage may be generated in the second coil 170. The magnitude of the induced voltage of the second coil 170 may vary according to the displacement of the AF moving part. It is possible to sense the displacement of the AF moving part by sensing the magnitude of the induced voltage generated in the second coil 170 and to perform the AF feedback operation using the detected displacement of the AF moving part, Can be performed.

14 shows the mutual inductance according to the separation distance between the first coil 120 and the second coil 170. FIG. The X axis represents the moving displacement of the AF moving part, and the y axis represents the magnitude of the mutual inductance.

14, the mutual inductance between the first coil 120 and the second coil 170 decreases as the distance between the first coil 120 and the second coil 170 decreases due to the movement of the bobbin 110, And as the mutual inductance increases, the induced voltage induced in the second coil 170 may increase.

On the other hand, the mutual inductance between the first coil 120 and the second coil 170 decreases as the distance between the first coil 120 and the second coil 170 increases, and as the mutual inductance decreases, The induced voltage induced in the capacitor 170 can be reduced.

Thus, the displacement of the AF moving part can be sensed based on the magnitude of the induced voltage generated in the second coil 170. [

In general, in order to perform AF (Auto Focus) feedback control, an AF moving part, for example, a position sensor capable of detecting the displacement of the bobbin and a separate power connection structure for driving the position sensor are required, And difficulty in manufacturing work may occur.

Also, the linear section (hereinafter referred to as "first linear section") of the graph between the moving distance of the bobbin and the magnetic flux of the magnet detected by the position sensor may be limited by the positional relationship between the magnet and the position sensor.

Since the embodiment does not require a separate position sensor for detecting the displacement of the bobbin 110, it is possible to reduce the cost of the lens driving apparatus and improve the ease of manufacturing work.

Since the mutual induction between the first coil 120 and the second coil 170 is used, the linear interval of the graph between the moving distance of the bobbin 110 and the induced voltage of the second coil 170, Can be increased. Accordingly, the embodiment can secure a wide range of linearity, improve the process defect rate, and perform more accurate AF feedback control.
