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.
