Abstract: A wearable apparatus includes a flexible display device, and a flexible housing that holds the peripheral portion of the flexible display device. The flexible display device is disposed on the uppermost surface of the apparatus to serve as a reference for defining the total length of the apparatus, and the portion of the apparatus below the flexible display device contracts along the direction of the total length.

Abstract: A wearable electronic device according to the present disclosure includes a first belt, front surface of the first belt being provided with a displaying unit having a curved display face; a second belt; a hinge that connects a first end of the first belt to a first end of the second belt. A shape of a space formed by the first and second belts is an elliptical shape when the device worn around a subject is viewed from a side. The hinge has higher flexibility than the first and second belts. The device has a first engagement unit provided at a second end and a rear surface of the first belt, and in a region where the elliptical shape has smaller curvature than other regions. The device has a second engagement unit provided at an outer side of the second belt and engaging with the first engagement unit.

Abstract: To provide a mount structure of an electromechanical acoustic transducer which enables making of an attempt to pursuit miniaturization while maintaining an acoustic characteristic. A cylindrical closed-end yoke 13 is attached to a frame 12, which is attached to an interior surface 11b of a housing 11 by way of a wall portion 19, in a direction where a bottom 13b of the yoke approaches the housing 11; hence, a sound channel 14 is defined between the yoke 13 and the wall portion 19 without an increase in the thickness of the electromechanical acoustic transducer. A superior acoustic characteristic can hereby be acquired. Alternatively, the sound channel 14 can be assured even when the electromechanical acoustic transducer is miniaturized, and thus an attempt can be made to pursuit miniaturization while maintaining an acoustic characteristic.

Abstract: An earpiece, an electronic device, and a communication device, capable of reducing the influence of leakage of sounds from a clearance between the earpiece and an ear not to need an addition of parts are provided. An earpiece (100) includes an electromechanical acoustic transducer (10) having a diaphragm and for generating a sound by vibrating the diaphragm in response to an electric signal, a case (11) on which a sound hole (12) is provided and in which the electromechanical acoustic transducer (10) is housed, and a holding member (13) for holding the electromechanical acoustic transducer (10) in the case (11). The electromechanical acoustic transducer (10) has a sound pressure-frequency characteristic that is compensated in advance such that the sound pressure-frequency characteristic is planarized in a condition that the generated sound is leaked from a user's ear (14) being covered with the case (11).

Abstract: Provided is a speaker unit, which is enabled by a simple constitution to retain characteristics such as a satisfactory output sound pressure. The speaker unit 100 has a frame including a first casing 11 and a second casing 14. A sound hole 12 is formed at the center of the upper face of the first casing 11, and a fixing portion 13 is formed on the inner face side. Between the fixing portion 13 and the second casing 14, there is interposed a vibration absorbing member 15. This vibration absorbing member 15 stabilizes the arrangement of a speaker 10, and absorbs the mechanical vibrations to be generated from the speaker 10 at the action time of the speaker 10, thereby to vibrate the speaker 10, the first casing 11 and the fixing portion 13 homogeneously. As a result, the sound to be emitted from the speaker 10 through the sound hole 12 and the sound to be emitted by the mechanical vibrations transmitted from the speaker 10, through the first casing 11 are efficiently emitted.

Abstract: A PC card includes a frame, a board mounted on the frame, and an upper cover and a lower cover for respectively covering an upper side and a lower side of the frame, slits formed to be penetrated from an abutting plane between the upper cover and the side portion of the frame up to another abutting plane between the lower cover and the side portion of the frame, claws used for the upper cover and the lower cover provided on inner wall surfaces of the slits, insertion projections respectively provided on the upper cover and the lower cover and inserted into the slits, and holes respectively formed in the insertion projections of the upper cover and the lower cover and inserted into the slits so as to be engaged with the claws.

Abstract: A portable cellular phone comprising a case body and a sliding cover is disclosed. The case body includes an operating section and stopper portions. The sliding cover covers the operating section of said case body and is slidably supported on said case body. The stopper portions of the case body restrict a sliding range of said sliding cover. The sliding cover is mounted and detached with respect to said case body by applying an outer force to the sliding cover in a direction perpendicular to a sliding direction when the sliding cover is positioned at a specific position within the sliding range. When the sliding cover is mounted, one of locking portions of the sliding cover is engaged with one of locking portions of the case body, and the other locking portion of the sliding cover is aligned in position on the other locking portion of the case body. The sliding cover is fit to the case body by applying an outer force.

Abstract: By providing pressing parts and a transmitting opening part to a cover for covering a key operation part and a transmitter of a housing by sliding, the key operation and the communication in carriage and in ten key operation are enabled, respectively. Moreover, the pressing parts can press different keys in carriage and in ten key operation. Locking nails are provided at the tip of a bowl-like shape, elongating form the end of the cover so that the locking nails are engaged with locking parts for locking with respect to the housing both in the carriage state and in the ten key operation state.
