Magnetic sensor array for crown rotation

A method of generating a signal corresponding to a rotational position of a crown operatively coupled to a body of an electronic device configured to be worn by a user, the crown comprising a housing, the method comprising:

• receiving, at an electronic circuit from a first magnetic sensing cell, a first signal corresponding to a position of the first magnetic sensing cell with respect to a magnet configured to remain stationary with respect to the body of the electronic device, wherein:
• the first magnetic sensing cell is attached to a rotating member comprising a flexible substrate disposed at least partially inside the housing,
• the crown is configured to rotate in a first direction in response to a mechanical input provided by the user, and
• the rotating member is configured to rotate in the first direction in response to the mechanical input;
• and
• generating, at the electronic circuit based on the first signal, a second signal corresponding to a rotational position of the crown with respect to the body of the electronic device.

An electronic device configured to be worn by a user comprising:

• means for rotating a crown in a first direction with respect to a body of the electronic device in response to a mechanical input provided by the user;
• first magnetic sensing means for detecting a first strength of a magnetic field corresponding to a magnet;
• second magnetic sensing means for detecting a second strength of the magnetic field corresponding to the magnet;
• means for selectively coupling one of the first magnetic sensing means and the second magnetic sensing means to an electronic circuit;
• and
• means for determining, based on an output of the first magnetic sensing means and an output of the second magnetic sensing means, a rotational position of the crown with respect to the body of the electronic device,
• wherein:
• the first magnetic sensing means and the second magnetic sensing means are disposed on a flexible substrate and are configured to rotate in the first direction in response to the mechanical input provided by the user, and
• the magnet is configured to remain stationary with respect to the body of the electronic device.
