Embodiment Construction

[0035] The invention provides an auxiliary device for integrating a projection cloth and a sound box, which can realize the simultaneous use of the sound box and the projection cloth.

[0036] The present invention provides an auxiliary device for integrating projection cloth and sound box, including:

[0037] The outer tube is provided with a slidable outer tube inside the outer tube.

[0038] The inner tube is sleeved with an outer tube outside the inner tube. It should be noted that the inner tube is not fixed inside the outer tube, but the inner tube and the outer tube are slidably matched to realize the sliding of the inner tube along the outer tube, so that the inner tube is gradually pulled out or inserted into the outer tube during the sliding process of the inner tube .

[0039] The supporting piece is movably connected with the inner pipe. The support can perform a certain rotational movement for unfolding or stowing. When the inner tube is pulled out of the oute...

Abstract

The invention provides an auxiliary device for integration of a projection screen fabric and a loudspeaker box. The loudspeaker box and the projection screen fabric can be used at the same time, and the auxiliary device for integration of the projection screen fabric and the loudspeaker box comprises an outer pipe, an inner pipe and a supporting part; the inner pipe is sleeved with the outer pipe,the inner pipe can slide along the outer pipe, the sliding part is movably connected with the inner pipe, the supporting part can be unfolded or folded, and when the supporting part is in the unfolding state, the supporting part is used for fixing the unfolded projection screen fabric. The loudspeaker box is arranged on the outer pipe, the projection screen fabric can be hung on the unfolded supporting part, the loudspeaker box and the projection screen fabric are integrated, and the vision and hearing needs can be met.

Description

technical field [0001] The invention relates to the technical field of multimedia output devices, in particular to an auxiliary device for integrating a projection cloth and a sound box. Background technique [0002] A projector is generally composed of a projection imaging system and an optical amplification system. The projection signal is processed by the imaging technology of the projector into an image signal, and then can be projected and displayed on the screen through the amplification of the optical system. During the projection process of the projector, music, voice, etc. are played at the same time. With the continuous improvement of the level of technology, people have higher and higher requirements for the light weight, miniaturization and portability of the projector. Layout design puts forward higher requirements. [0003] Existing projector products are usually installed separately from the speakers, and have disadvantages such as complex structure, inconven...
