Problems solved by technology

[0003] But when a motor with anti-shake function is installed in a dual-camera mobile phone, the magnet and coil will generate a strong magnetic field in the energized state, which in turn will generate strong magnetic interference to the Hall sensor in the other motor
[0004] In the prior art, the magnetic interference of the motor with anti-shake function in the dual-camera mobile phone to the Hall sensor in the other motor is avoided through software, but this will cause a decline in the camera experience (for example, focusing time)

Embodiment Construction

[0048] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0049] In order to facilitate understanding of the embodiments of the present application, the following elements are firstly introduced before introducing the embodiments of the present application.

[0050] The working principle of the Auto Focus (AF) motor is to generate a magnetic field by energizing the coil inside the motor, and move the lens according to the magnetic field force. The AF motor determines the position of the lens by measuring the magnetic field strength through the Hall sensor, and then moves the entire lens through a small distance. position, control the length of the focal length, and then realize the clarity of the image. Among them, AF motors mainly include voice coil motors, stepping motors, liquid lens focusing, memory alloy motors, and liquid crystal lens focusing. The m...

Abstract

The embodiment of the invention provides a double-camera device. The double-camera device comprises a first camera, wherein the first camera comprises a first motor, and the first motor comprises at least one first Hall sensor; and a second camera, wherein the second camera comprises a second motor, the second motor and the first motor are arranged side by side, the second motor comprises N secondcoils and N second magnets, the second coils are used for suspending and supporting the second magnets in the case of power-on, N is a positive integer, N is a multiple of 4, and the distance betweena first setting position of the first Hall sensor in the first motor and a second setting position of the second magnet in the second motor is greater than a first preset distance. The technical scheme of the invention can reduce the magnetic interference of the motor with an anti-shake function to the Hall sensor in the other motor and improve the user experience.

Description

technical field [0001] The present application relates to the communication field, and more specifically, to a dual-camera device and a terminal device. Background technique [0002] At present, the application of dual cameras in mobile phones is becoming more and more popular. The usual dual cameras are composed of two motors with focusing function. Among them, the motor determines the position of the lens by setting the Hall sensor to measure the magnetic field strength, and then achieves focusing. . In addition, cameras with anti-shake function are becoming more and more popular, and the anti-shake function is mainly realized by four magnets and four coils used to suspend and support the magnet in the electrified state. [0003] However, when a motor with anti-shake function is installed in a dual-camera mobile phone, the magnet and coil will generate a strong magnetic field in the energized state, which will generate strong magnetic interference to the Hall sensor in th...
