Abstract
A dual-camera device includes a first camera, and a second camera, where the first camera includes a first motor, and the first motor includes at least one first Hall effect sensor, where the second camera includes a second motor, the second motor and the first motor are disposed in parallel, the second motor includes N second coils and N second magnets, the second coils are configured to levitate and support the second magnets during power-on, N is a positive integer and is a multiple of four. A distance between a first disposition location of the first Hall effect sensor and a second disposition location of the second magnets in the second motor is greater than or equal to a first preset distance.

A dual-camera device, comprising:
- a first camera, wherein the first camera comprises a first motor, and wherein the first motor comprises at least one first Hall effect sensor;
- and
- a second camera, wherein the second camera comprises a second motor,
- wherein the second motor and the first motor are disposed in parallel, wherein the second motor comprises N second coils and N second magnets, wherein the N second coils are configured to levitate and support the N second magnets during power-on, wherein N is a positive integer, wherein N is a multiple of four, wherein a distance between a first disposition location of the at least one first Hall effect sensor in the first motor and a second disposition location of the N second magnets in the second motor is greater than or equal to a first preset distance, and wherein the first preset distance is less than or equal to a maximum distance achievable between internal components of the dual-camera device and is set to reduce magnetic interference between the first motor and the second motor.
A terminal device, comprising:
- a first camera, wherein the first camera comprises a first motor, and wherein the first motor comprises at least one first Hall effect sensor;
- and
- a second camera, wherein the second camera comprises a second motor, wherein the second motor and the first motor are disposed in parallel, wherein the second motor comprises N second coils and N second magnets, wherein the N second coils are configured to levitate and support the N second magnets during power-on, wherein N is a positive integer, wherein N is a multiple of four, wherein a distance between a first disposition location of the at least one first Hall effect sensor in the first motor and a second disposition location of the N second magnets in the second motor is greater than or equal to a first preset distance, and wherein the first preset distance is less than or equal to a maximum distance achievable between internal components for the first camera and the second camera and is set to reduce magnetic interference between the first motor and the second motor.
