Abstract: An electronic apparatus appropriately outputs low-frequency sound to high-frequency sound to enable acoustic reproduction with high sound quality is disclosed. A portable information apparatus includes a first speaker; and an expansion device includes a second speaker. The portable information apparatus includes a mode switching unit for selecting a single mode or a combined mode; and an acoustic adjustment unit for adjusting acoustic data output to the first speaker and/or the second speaker. During the single mode, the acoustic adjustment unit outputs the acoustic data to the first speaker. During the combined mode, the acoustic adjustment unit extracts high-frequency sound from the acoustic data and outputs the high-frequency sound to the first speaker, and extracts low-frequency sound from the acoustic data and outputs the low-frequency sound to the second speaker.

Abstract: An electronic device having a member for chassis is disclosed. The member for chassis includes a surface layer, a rear layer disposed inside of the surface layer in a thickness direction, and an intermediate layer disposed between the surface layer and the rear layer. Each of the surface layer and the rear layer includes a fiber-reinforced resin plate. The intermediate layer is made of a material that is compressible in the thickness direction. The member for chassis further includes a fastening hole that penetrates through the surface layer, the intermediate layer and the rear layer, through which a fastener passes to fix the member for chassis to a member for attachment. The surface layer includes a cut line having a larger diameter than the fastening hole in order to surround the fastening hole.

Abstract: An electronic apparatus having a sub display is provided. The electronic apparatus includes a hinge mechanism connecting a main body chassis and a display chassis; a movable plate provided on a top surface of the main body chassis and is turnable in a direction in which its rear end moves up and down around a rotating shaft part provided at its front end; a drive mechanism that turns the movable plate in conjunction with a turning operation between the main body chassis and the display chassis by the hinge mechanism; and a release mechanism that releases an interlocking state of the turning operation and the movable plate by the drive mechanism to allow the movable plate to turn in a downward direction when the movable plate of which the rear end is located at a raised position receives a predetermined external force in the downward direction.
