摘要:
A cradle for connecting to a portable electronic apparatus is described. The cradle includes an AC adapter connector, a USB connector, a mini USB plug, and a USB signal detecting circuit. The USB connector is used to connect to a USB interface of a computer. The mini USB plug is used to connect to the portable electronic apparatus. The USB signal detecting circuit detects the USB_D+ and the USB_D− of the USB connector. When the computer is suspended from an operating state, the portable electronic apparatus is charged by the AC adapter through the mini USB plug. When the computer resumes normal operation, the USB connection between the portable electronic apparatus and the computer is automatically reestablished.

An electronic device is provided. The electronic device includes a housing and an electro-acoustic transducer disposed on the inner surface of the housing. The electro-acoustic transducer includes an electret diaphragm, a conductive plate and at least one spacer. The electret diaphragm is positioned on the inner surface of the housing and has a film body and an electrode layer. The film body has static charges and the electrode layer is formed on the lower surface of the film body. The conductive plate has a plurality of openings and is stacked on the upper surface of the film body. The spacer is positioned between the electret diaphragm and the conductive plate to keep a predetermined distance therebetween.

The invention provides an electronic device and an electro-acoustic transducer thereof. The electronic device includes a main body and an electro-acoustic transducer carried by the main body. The electro-acoustic transducer includes a first electret diaphragm, a second electret diaphragm and a plate. The first electret diaphragm generates vibrations according to a first electrical signal and the second electret diaphragm generates vibrations according to a second electrical signal. The plate includes a plurality of holes formed thereon and is disposed between the first electret diaphragm and the second electret diaphragm. Additionally, the electronic device further includes a decorative layer formed on the first or the second electret diaphragm.
摘要:
A portable electronic device and an autofocus control method of a camera of the portable electronic device are disclosed. The portable electronic device provides a G-sensor to detect the orientation of the portable electronic device, and provides a storage unit to store autofocus lookup tables for different orientations of the portable electronic device, respectively. According to orientation information from the G-sensor, the central processing unit of the portable electronic device selects one autofocus lookup table from the storage unit and thereby generates an actuating signal for a focus model. The focus model of the portable electronic device is actuated by the actuating signal to adjust an image distance between a lens module and an image sensor of the camera.
