A wireless sound output device includes a wireless earbud and a charging base. The wireless earbud is placed in the charging base. If a true wireless stereo Bluetooth controller of the wireless earbud detects that a mode switching circuit of the charging base is switched to a wireless Bluetooth receiver mode, an analog signal is transmitted to an audio source output hole of the charging base through an audio source analog signal output switching unit of the wireless earbud.

A camera module testing method is applied to a camera module including a camera lens and a photosensitive element. In a step (A), an original image is captured through the camera lens and the photosensitive element. In a step (B), the original image is converted into a gray scale image. In a step (C), the gray scale image is converted into a binary image according to a critical gray scale value. In a step (D), a boundary contour is obtained according to plural pixels of the binary image higher than or equal to the critical gray scale value. In a step (E), a contour center of the boundary contour is obtained. Then, a step (F) is performed to judge whether an optical axis of the camera lens is aligned with an imaging center of the photosensitive element according to the imaging center and the contour center.

An information management method for a testing network framework is provided. The testing network framework includes a first server and at least one computer. The method includes the following steps. Firstly, the at least one computer downloads and executes a test application program. Then, the at least one computer is connected to the first server, and provides a device identification code and a network address value of the at least one computer to the first server. If the first server judges that the corresponding device identification code complies with a first default condition and the corresponding network address value complies with a second default condition, the corresponding computer is authenticated, and a test setting information is provided from the first server to the corresponding computer. After the test setting information is downloaded to the corresponding computer, a test process is performed.
