  • Publication number: 20140247959
    Abstract: A display apparatus includes: a display panel; a speaker provided behind the display panel; a cover including a front cover component covering an outer peripheral portion of the display panel from the front and a back cover component covering the display panel from behind; and a speaker securing component which secures the speaker to emit sound away from the display panel. The speaker securing component and the back cover component form therebetween a sound guiding space which guides, in a first direction toward a side surface of the display panel, the sound emitted from the speaker and further guides the sound guided in the first direction toward the front. In the sound guiding space, a speaker-facing region of the back cover component intersects with a plane perpendicular to an emission direction of the speaker such that the emission direction points toward the first direction.

  • Patent number: 8253050
    Abstract: When the assembly is complete, the protrusion 2e of the leaf spring 2b abuts against the bottom wall surface 3g which is an inner bottom surface of the cover member 3 and the leaf spring 2b is bent. Since the protrusion is pushed against the cover member 3, the leaf spring 2b generates force of repulsion which pushes the frame member 2f toward the opposite direction of the cover member 3. In addition, since the leaf springs 2b are aligned straightly between three bosses 3b, the leaf spring 2b pushes the push button 2 toward the switch board 1 almost in parallel. In other words, if the push button 2 is held in the cover member 3, without further components, the push button 2 is pushed against the switch board 1 and there will not be a possibility of a wobble.

  • Patent number: 7663885
    Abstract: The IC fixing component includes a locking case accommodating the IC in such a manner that a side of the IC out of a face-to-face contact with the heat dissipation plate is brought into a face-to-face contact with the locking case so as to be covered and a through hole and a rotation stop protrusion inserted into a rotation limiting hole. After the IC has been accommodated in the locking case, the screw member inserted through the through hole is screwed into a screw hole of the heat dissipation plate so that the side of the IC out of face-to-face contact with the locking case is pressed by the locking case thereby to be brought into a face-to-face contact with the heat dissipation plate.

  • Patent number: 7515222
    Abstract: Conventionally, a fixing bracket attached to a rear inside wall of a main body of a liquid crystal television set or a liquid crystal display would interfere with the main body, generating chatter. A hook part having a bent tip erected in a protruding manner from a rear inside wall of a main body of a liquid crystal television set or a liquid crystal display is passed through a second through hole of a fixing bracket from the inside wall side to a front side of the main body. A peripheral portion of the second through hole is inserted in a recess of the rear inside walls of the main body, and is hooked there. Accordingly, when the fixing bracket is hooked, the fixing bracket and the tip of the boss erected from the rear inside wall of the main body come in contact with each other to be fixed.
