    Abstract: One embodiment provides a method of audio upmixing comprising performing video scene analysis by segmenting visual objects from video frames of a video, and performing audio analysis by extracting audio signals from an audio corresponding to the video. The method further comprises determining whether any of the audio signals correspond to any of the visual objects, and estimating a video-based trajectory of a visual object if the visual object is in motion and transitions from on-screen to off-screen, or vice versa, during the video. The method further comprises positioning an audio trajectory of an audio signal from at least one speaker associated with the display to at least one other speaker associated with providing surround sound. The audio trajectory is automatically matched with the video. The audio signal is delivered to the at least one speaker and the at least one other speaker for audio reproduction during the presentation.

    Abstract: One embodiment provides a method that includes receiving, by a processor, port tube design parameters for a port tube for a speaker device. The method further includes predicting, by the processor, pressure and pressure gradients by performing a numerical simulation process based on the port tube design parameters. The processor further determines a measure of shear within the port tube and at exits of the port tube based on the predicted pressure and pressure gradients. The method additionally includes updating, by the processor, the port tube design parameters and repeating performing the numerical simulation and the determining of the measure of shear until a minimized shear measure result is determined.

    Abstract: One embodiment provides a slim acoustic transducer with a diaphragm including a hole that is substantially centered on a vertical axis of the diaphragm. The hole has a first horizontal width. A voice coil has a ring shape that is disposed at least partially within the hole and substantially centered on the vertical axis. The ring shape has an outer and inner horizontal width. The outer horizontal width is smaller than or equal to the first horizontal width of the hole. A column structure is disposed at least partially within the ring shape and substantially centered on the vertical axis. The column structure has a second horizontal width that is smaller than or equal to the inner horizontal width of the ring shape. The column structure includes an upper magnet, a middle plate disposed below the upper magnet and a lower magnet disposed below the middle plate.
