Provided is a sound output device including a drive unit that has a sound output section inside and that is formed in an annular shape and an electric unit that has a drive control section inside and that is coupled to the drive unit. A space inside the drive unit is formed as an intake hole that takes in an external sound. The sound output device is attached to an ear with the drive unit inserted into a cavum concha. Accordingly, in a state in which the electric unit is coupled to the drive unit and the drive unit is inserted into the cavum concha to be attached to the ear, an external sound taken in from the intake hole that is the space inside the drive unit goes to the external auditory canal. Therefore, a stable and favorable wearing state on the ear can be ensured, and at the same time, a state in which an external sound is taken in naturally can be ensured.

Sound output device

The purposes of the present invention are to improve safety of data transmission and a data transfer rate and to reduce an increase in costs for the improvement. An encryption unitof a transmission devicegenerates encrypted data that allow plain data thereof to be uniquely identified A segmentation unitsegments the encrypted data into two types of basal signal point number information on the basis of map data provided by a map management unit. A basal signal point number generation unitgenerates basal signal point number information used as information to be transmitted, on the basis of a set of the two types of information, i.e. horizontal basal signal point number information and vertical basal signal point number information.

Information processing device for transmitting information

The present invention improves data transmission safety and data transfer rate, and reduces an increase in costs when doing so. A map management unitmanages a map which defines a prescribed rule for dividing pseudorandom number data into two. On the basis of the rule defined by the map, a division unitgenerates data obtained by dividing the pseudorandom number data into two as vertically irregular mapping input data and horizontally irregular mapping input data. A vertically irregular mapping unitgenerates data obtained by subjecting the vertically irregular mapping input data to irregular mapping processing as vertical base reference point data. A horizontally irregular mapping unitgenerates data obtained by subjecting the horizontally irregular mapping input data to irregular mapping processing as horizontal base reference point data. A base reference point information generation unitdecides on one base on the basis of the vertical base reference point data and the horizontal base reference point data.

Information processing device

A blade driving device including, a base plate including an opening through which light passes, a blade configured to runs on a surface of the base plate to open and close the opening, a drive mechanism including a drive spring and actuates the blade; and a charge mechanism configured to perform a charge operation on the drive mechanism against the drive spring. The charge mechanism includes a slide member configured to linearly reciprocate in a direction parallel to the base plate along a motor between the motor and the drive mechanism, the motor generating a driving force for the charge mechanism.
