20200236450 | VIBRATION CANCELLING SPEAKER ARRANGEMENT - A speaker assembly for being mounted within a wall is provided. The speaker assembly has a housing and a plurality of transducers supported by the housing. Each transducer has a front radiation surface and a radiation rear surface adapted to radiate sound along a central axis. The transducers are arranged relative to each other so the central axes of acoustic radiation of each of the transducers intersect at a circumcenter defined between the plurality of transducers to substantially cancel vibrations from the plurality of transducers. A slot is formed adjacent of each of the transducers. The slot extending a depth dimension of the assembly between a slot opening for transmitting acoustic radiation from the plurality of transducers and a back wall of the housing, wherein the depth dimension is generally perpendicular to the central axes of acoustic radiation of each of the transducers. | 2020-07-23 |
20200236451 | ELECTRONIC DEVICE - An electronic device including a display panel, a protection layer, and a sound broadcasting element is provided. The protection layer is disposed on the display panel. The sound broadcasting element and the display panel are both located below the protection layer, and the sound broadcasting element contacts the protection layer. | 2020-07-23 |
20200236452 | Display Apparatus - A display apparatus includes a display panel configured to display an image by emitting light, and a sound generation device including a vibration generation module configured to vibrate the display panel. The vibration generation module includes a vibration element on a rear surface of the display panel, and a vibration reflecting member on the rear surface of the display panel and spaced apart from the vibration element. | 2020-07-23 |
20200236453 | MICROPHONE - A microphone including a light emitting part can be miniaturized. | 2020-07-23 |
