Abstract: A display apparatus includes a liquid crystal display panel and a backlight module, a first sealed air cavity formed inside the liquid crystal display panel, and the backlight module being located on one side of the liquid crystal display panel and forming a second sealed air cavity with the liquid crystal display panel; and a sound-emitting board and a sound-emitting exciter, the sound producing board being fixed to the surface of the backlight module far away from the liquid crystal display panel, and a vibration output terminal of the sound-emitting exciter being fixed to the surface of the sound-emitting board far away from the backlight module.

Abstract: An offshore rocket transport and launch method includes S1: assembling a rocket horizontally; S2: loading the assembled rocket as a whole into a transport cage; S3: transporting, by a transport vehicle, the transport cage loaded with the rocket to a wharf by land horizontal transport; S4: transferring the transport cage loaded with the rocket to a transport ship, and transporting the transport cage loaded with the rocket to an offshore rocket launch pad by sea transport; S5: hoisting, by a hoisting device, the transport cage loaded with the rocket to the rocket launch pad; S6: opening the transport cage, transferring the rocket to a launching position, and hoisting the transport cage away from the rocket launch pad; and S7: launching the rocket. The method effectively facilitates the offshore rocket transport and launch process, and prevents the rocket from being affected by the external environment during the launch process.
