Abstract: A speaker unit includes: a speaker that contains a magnet for vibrating a diaphragm to output sound; a speaker housing unit that houses the speaker so that the front of the diaphragm is exposed outside; an opening-and-closing unit that is attached to the speaker housing unit so that the opening-and-closing unit can both open, with respect to the speaker housing unit, to expose the front of the diaphragm outside and close to cover the front of the diaphragm; and a metallic component that is, when the opening-and-closing unit is closed with respect to the speaker housing unit, attracted to the magnet of the speaker to pull the opening-and-closing unit in a closing direction.

Abstract: An input device is disclosed which includes: a casing; an input unit provided in the casing; an orientation detection unit configured to detect the orientation of the casing; and a command assigning unit configured to assign commands to inputs from the input unit, based on the results of detection by the orientation detection unit.

Abstract: A process execution apparatus and method is disclosed by which a process can be executed significantly simply and readily. The process execution apparatus includes a direction recognition section for recognizing a housing member shaking direction in which a housing member is shaken, and a process execution section for executing a process in response to the housing member shaking direction recognized by the direction recognition section. The direction recognition section recognizes the housing member shaking direction with respect to a direction of the gravity detected when the housing member is held by a person.

Abstract: A reproduction apparatus includes a storage part which stores a plurality of items of contents data; reproduction means for reproducing contents in any one of reproduction modes including a normal reproduction mode that reads the contents data stored in the storage part in a predetermined order for reproduction, and a recommend mode that selects one part of the contents data stored in the storage part as a recommended piece of music for reproduction; and reproduction mode control means for changing the reproduction mode in the reproduction means to the recommend mode when a predetermined recommend mode changing condition is satisfied.

Abstract: A reproducing apparatus includes a storage unit having a plurality of content data stored therein, a reproducing unit reading out the content data stored in the storage unit and reproducing the read content data, and a driving unit driving a predetermined driven unit according to the content of the content data reproduced in the reproducing step. The reproducing unit has two reproduction modes, that is, a normal reproduction mode in which the content data stored in the storage unit are reproduced in a predetermined order and a recommend mode in which some of the content data stored in the storage unit are selected as recommended music files and the selected content data are reproduced. When the reproducing unit operates in the recommend mode, the driving unit drives the driven unit more quickly than in the normal reproduction mode.

Abstract: An authenticating pattern is disposed on a cover and an authenticating device is disposed in a robot apparatus for authenticating the cover on the basis of the authenticating pattern of the fitted cover. An information holding device for holding inherent information is disposed in the cover and a reading device for reading out the inherent information from the information holding device is disposed in the robot apparatus. A function of detecting an amount of influence due to the cover and changing manifesting patterns of motions as occasion demands on the basis of the detection result is disposed in the robot apparatus.

Abstract: Firstly, a authenticating pattern is disposed on a cover and an authenticating means is disposed in a robot apparatus for authenticating the cover on the basis of the authenticating pattern of the fitted cover. Secondary, an information holding means for holding inherent information is disposed in the cover and a reading means for reading out the inherent information from the information holding means is disposed in the robot apparatus. Thirdly, a function of detecting an amount of influence due to the cover and changing manifesting patterns of motions as occasion demands on the basis of the detection result is disposed in the robot apparatus.
