Voice coil motor array module
View Patent ↗A voice coil motor array module includes a carrier, and a plurality of voice coil motors disposed on the carrier and arranged side by side in at least one row along an arrangement direction. Each voice coil motor includes a lens holder having a holder body and a coil wound around the holder body, and two magnetic components respectively disposed on two opposite sides of the holder body and having the same magnetic poles facing each other. When the coil is energized, the coil interacts with the magnetic components to drive displacement of the holder body along a direction parallel to a normal direction of a plane of the arrangement direction.
1. A voice coil motor array module comprising:
a carrier; and
a plurality of voice coil motors disposed on said carrier and arranged side by side in at least one row along an arrangement direction, each of said voice coil motors including:
a lens holder having a holder body and a coil wound around said holder body, and
two magnetic components respectively disposed on two opposite sides of said holder body and having the same magnetic poles facing each other, wherein, when said coil is energized, said coil interacts with said magnetic components to drive displacement of said holder body along a direction parallel to a normal direction of a plane of the arrangement direction.
2. The voice coil motor array module as claimed in claim 1 , wherein said magnetic components are opposite to each other along a line that is inclined with respect to the arrangement direction at an angle ranging from 45 degrees to 90 degrees.
3. The voice coil motor array module as claimed in claim 1 , wherein said magnetic components are opposite to each other along a line that is perpendicular to the arrangement direction.
4. The voice coil motor array module as claimed in claim 1 , wherein: said magnetic components of one of said voice coil motors are opposite to each other along a first line perpendicular to the arrangement direction, and said magnetic components of an adjacent one of said voice coil motors are opposite to each other along a second line parallel to the arrangement direction, said first and second lines being perpendicular to each other.
5. The voice coil motor array module as claimed in claim 1 , wherein said voice coil motors are arranged in multiple rows along the arrangement direction.
6. The voice coil motor array module as claimed in claim 5 , wherein: said magnetic components of one of said voice coil motors are opposite to each other along a first line perpendicular to the arrangement direction, and said magnetic components of an adjacent one of said voice coil motors are opposite to each other along a second line parallel to the arrangement direction, said first and second lines being perpendicular to each other.
7. The voice coil motor array module as claimed in claim 1 , wherein said magnetic components of each of said voice coil motors are parallel to each other.
8. The voice coil motor array module as claimed in claim 1 , wherein said carrier is a circuit board coupled electrically to said voice coil motors.
