Embodiment Construction

[0040] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0041] An audible screen is a screen that emits sound, such as figure 1 As shown in , it is a structural schematic diagram of a sound emitting screen. The sounding screen 10 may include a screen, an auxiliary sounding board, a speaker, a frame and a backboard.

[0042] Such as figure 2 shown, which is figure 1 In the shown sounding screen, the top view of the auxiliary sounding board 11 . The auxiliary sounding board includes a plurality of honeycomb cavities arranged in an array, and each cavity has the same volume. The vibration emitted by the loudspeaker can drive the gas in the cavity to vibrate, and then drive the entire auxiliary sounding plate to vibrate to produce sound.

[0043] But under the electrical signal driv...

Abstract

The invention discloses a sound production screen and a projection television, and belongs to the field of audio and video equipment. The sounding screen comprises a display function layer and an audio component; the audio component comprises an auxiliary sound production layer and a plurality of loudspeakers, the auxiliary sound production layer is stacked on one side of the display function layer, and orthographic projection arrays of the loudspeakers on the auxiliary sound production layer are arranged on the auxiliary sound production layer; the auxiliary sound production layer is provided with at least two sound production areas, each sound production area is provided with a plurality of cavities, and each sound production area is provided with a first cavity and a second cavity which are different in size. According to the sound production screen, the cavities with different volumes are arranged in the different areas of the auxiliary sound production layer, so that when the loudspeaker drives the auxiliary sound production layer to vibrate, the vibration frequencies of the different areas are different due to the difference of the volumes of the cavities, and therefore, the sound production screen can produce sounds with various frequencies; the problem that the sound effect of the sound emitted by the sound production screen is poor in the prior art is solved, and the effect of improving the sound effect of the sound emitted by the sound production screen is achieved.

Description

technical field [0001] The present application relates to the field of audio and video equipment, in particular to a sound emitting screen and a projection TV. Background technique [0002] The sound-emitting screen is a screen capable of emitting sound, which can emit sound as a sound while displaying a picture, and the user experience is better. [0003] A sound-emitting screen, including a display function layer, an auxiliary sound-emitting layer, and a plurality of speakers arranged on the auxiliary sound-emitting layer, the display function layer is used to realize the display function, and the speakers are used to drive the auxiliary sound-emitting layer to vibrate under the drive of electric power , and then make a sound. [0004] During the process of implementing the present application, the inventors found that the related art has at least the following problems: the sound effect of the sound emitted by the above-mentioned sound-emitting screen is poor.
