A sound management system for a multimedia display apparatus includes: a first audio device built in a display apparatus to provide first audio, a second audio device separated from the display apparatus to provide second audio, a portable device separated from both the display and the second audio device, optionally being moved to the first or second position to receive and analyze either a first sound field at a first position or a second sound field at a second positions respectively formed by the first audio and the second audio, and a controller used to notify the first and/or second audio devices to adjust the first and/or second audio according to the analysis to synthesize either a first adjusted sound field at the first position or a second adjusted sound field at the second position with sound characteristics similar to that of a target sound audio.

Sound management system for multimedia display apparatus and managing method thereof

A projection system including at least a light source, at least a dichroic filter element and a light-adjusting diaphragm element is provided. The light source is configured to emit a first color light having a spectrum of a first wavelength range and a second color light having a spectrum of a second wavelength range. The dichroic filter element is configured to reflect or allow the first color light and the second color light to pass through. The light-adjusting diaphragm element has a filter and is located on an optical path generated after the first color light and the second color light are split. The first color light passes through the filter, which blocks at least a part of the energy of the second color light, such that a transmittance of the spectrum of the first wavelength range is greater than that of the spectrum of the second wavelength range.
