Summary: | To provide a vibration apparatus that can vibrate a display panel to generate a sound and is improved in a sound characteristic and/or sound pressure characteristic, and an apparatus including the same.SOLUTION: An apparatus comprises a display panel 100 configured to display an image, a vibration apparatus 200 disposed at a rear surface of the display panel and configured to vibrate the display panel, a supporting member 300 at the rear surface of the display panel, and a pad member 700 between the vibration apparatus and the supporting member. The pad member is configured for decreasing a dip phenomenon of the vibration apparatus, and the dip phenomenon at 3-4 kHz is mitigated. A sound at a frequency of 3-4 kHz may affect the articulation of a sound and, when the dip phenomenon occurs at the frequency, a sound output characteristic is reduced by an unclear sound.SELECTED DRAWING: Figure 19
【課題】表示パネルを振動させて音響を発生させることができ、音響の特性および/または音圧の特性が向上された振動装置及びそれを含む装置を提供する。【解決手段】装置は、映像を表示する表示パネル100、表示パネルの背面にあり、表示パネルを振動させる振動装置200、表示パネルの背面にある支持部材300および振動装置と支持部材の間にあるパッド部材700を含む。パッド部材は、振動装置のディップ(dip)現象を軽減するために構成され、3kHzから4kHzでのディップ現象が改善される。3kHzから4kHzの周波数での音響は、音響の明瞭度に影響を与え、この周波数でディップ現象が発生した場合、不鮮明な音響により音響の出力特性が低下する。【選択図】図19 |
