A hand-held or palm mobile mouse is contained in a mini handheld shaped housing to be held in the palm of a user with a sphere arranged on the top easily and naturally reached by the user's thumb. The thumb of the user can rotate the sphere, which contains a magnetic core inside, to cause a corresponding cursor movement on a computer screen through a magnetically activated rolling movement detection unit or units and press down on the sphere to carry out click function commands or menu functions pointed to by the cursor on the screen. Alternatively, the magnetic core may be omitted by supporting the sphere on four free rolling roller units, two of which are used to implement the rolling movement detection function. There may also be key-buttons on the area where the user's fingers rest to implement click function by a user's fingers. There may also be a wheel/click button for cursor extension movement and click command functions. The mouse is padless, wire-less, freely used in any direction or position for the comfort of a user's wrist, and easily carried by a user for convenience. The remote wireless signals of the mouse or additional mice can be programmed for user identification, for added security. The mouse is a flexible and convenient input device for computers, especially miniaturized notebook computers.

The earphone includes an ear cup, at least one speaker disposed in the ear cup, a processing unit disposed in or attached to the ear cup and connected to the speaker, and at least one sensor disposed in or attached to the ear cup and connected to the processing unit. The sensor is configured to sense a movement of the earphone or an environmental change of the earphone and to send the processing unit a signal representing the movement or the environmental change. The processing unit is programmed to process the signal and to generate a changed stereo signal for the speaker. The changed stereo signal is changed according to the movement or the environmental change. The speaker is configured to receive the changed stereo signal and to generate a changed stereo sound effect according to the changed stereo signal.
