Abstract: In an information searching method for an electronic device an image is read from a storage device and a keyword corresponding to the read image is received by the electronic device. The read image is transmitted to a server which provides an image searching function. The method acquires result-of-search pictures which match the read image and source URLs of the result-of-search pictures from the server. The method analyzes data on web pages of the acquired source URLs and obtains groups of matching information which match the received keyword according a preset searching rule corresponding to the received keyword in the storage device. The method further determines optimal matching information with the highest occurrence frequency in the groups of matching information to be output as a search result.

Abstract: A method for downloading a file from a server device using a client device. The client device includes a plurality of electronic devices. The method includes sending a file downloading request to the server device from one of the electronic devices, and sending an assist request to each of the other electronic devices of the client device, thus, enabling each of the electronic devices to receive a segment of the file from the server device. A complete file can be generated according to the segments of the file from the server device received by the electronic devices.

Abstract: A portable electronic device includes a built-in speaker, an interface configured to connect to an external audio device to output sound, a switch, and a main microchip. The main microchip detects whether the external audio device is connected to the portable electronic device. When the external audio device is connected to the portable electronic device, the main microchip selects the audio device to output sound. When the audio device is not connected to the portable electronic device, the main microchip selects the built-in speaker to output the audio signals.

Abstract: An electronic device includes a first housing, a second housing engaged with the first housing, a circuit board enclosed between the first and second housings, two speakers, and an antenna. The speakers and the antenna are attached to two sides of the circuit board. The first housing defines two receiving recesses in a surface facing the circuit board and two first through holes each adjacent to one corresponding receiving recess. Each receiving recess defines a second through hole in a bottom. The speakers are received in the receiving recesses. The receiving recesses communicate with the vents to form front resonating chambers for the speakers. The circuit board defines two third through holes aligned with the first through holes and communicating with the recessed sections. The first, second, and third through holes, the recessed sections, and the vents communicate with each other to form back resonating chambers for the speakers.

Abstract: A portable electronic device includes a main body, a camera, a primary display unit, a secondary display unit, and a screen control unit. The main body includes a first surface and a second surface opposite to the first surface. The camera is positioned in the main body. The primary display unit is positioned on the first surface. The secondary display unit is positioned on the second surface. The screen control unit is electronically connected to the camera, the primary display unit, and the secondary display unit. The screen control unit receives an image captured by the camera, processes the received image and sends the processed image to the primary display unit or the secondary display unit.

Abstract: A sound amplifying device includes a base part and an amplifying part. The amplifying part is mounted on the base part. The amplifying part includes a reflecting wall and a bracket. The reflecting wall has a hollow semi-ellipse shape with a semi major axis and a minor axis. The bracket is mounted on the reflecting wall and has one end positioned on the semi major axis. An electronic product using the sound amplifying device includes the sound amplifying device and an electronic device removably mounted on the sound amplifying device. The sound amplifying device generates a maximum loudness effect.
