Abstract: An ergonomic mouse has a sliding cap matching the curvature of a normal human palm. The sliding cap may be slid on the top of a hollow body to reach a desired operation position, then fine-tuned and anchored. Thus when the mouse is moved during operation, it can absorb reaction forces to avoid hurting the user's wrist and better meet ergonomic requirements.

Abstract: A video/audio combo device includes a picture-taking element for taking pictures and a sound-generating element to output sound. It has a housing shell located in a portable electronic data processing device with the picture taking element and the sound-generating element jointly housed in the housing shell. While the picture-taking element can take pictures, the housing shell has a remained space to serve as a resonant space to enable the sound-generating element to achieve an improved audio output effect.

Abstract: An electrical apparatus with a rotating stage set pivotally connecting to a host shell, and an antenna module pivotally connecting to the rotating stage set is provided. The rotating stage set rotates about the X-axis, and the antenna module rotates about the Y-axis with respect to the host shell. In addition, the electrical apparatus can thus obtain the best signal receiving and transmitting efficiency by adjusting the antenna module to the best receiving and transmitting position and angle.

Abstract: A coupling structure for a handheld electronic device and a back cartridge thereof includes a first coupling assembly and a second coupling assembly. The first coupling assembly is located on the handheld electronic device. The second coupling assembly is located on the back cartridge corresponding to the first coupling assembly, and has a coupled position and a stored position. At the coupled position the second coupling assembly is extended outside the back cartridge to couple with the first coupling assembly, to thereby enable the handheld electronic device to couple with the back cartridge. At the stored position, the second coupling assembly is held in the back cartridge to allow the handheld electronic device to be separated from the back cartridge. Hence, the handheld electronic device and the back cartridge can maintain an integrated and self-contained profile.
