Embedded sound shielding and directional transmission integrated device for indoor meeting place

Abstract

The invention relates to an embedded sound shielding and directional transmission integrated device for an indoor meeting place, which comprises a bearing base, a swing mechanism, an operation box, adistance measuring device, a sound sensor, a noise sensor and a control circuit, and is characterized in that the cross section of the bearing base is of a U-shaped groove-shaped structure, and the operation box is embedded in the bearing base; the operation box is hinged to the bearing base through a swing mechanism, the swing mechanism and the bearing base are coaxially distributed and can rotate within the range of 0-350 degrees, the operation box comprises a bearing groove, a protective back plate, a protective net plate, a partition plate, a sound guide cone, a directional loudspeaker andelastic silencing cotton, and the distance measuring device, the sound sensor and the noise sensor are embedded in the front end face of the top of the bearing base. On one hand, the capacity of resisting external force impact, dust, liquid and other pollutants can be effectively improved, and on the other hand, the operation power can be flexibly adjusted according to the distance of sound propagation operation, and environmental noise is shielded.

Description

technical field [0001] The invention relates to a loudspeaker structure, in particular to an embedded sound shielding and directional transmission integrated device for an indoor meeting place. Background technique [0002] At present, in conference rooms, stage theaters and other occasions, in order to improve the transmission distance and quality of sound waves, and at the same time prevent noise pollution caused by sound wave diffusion, information leakage, and sound wave transmission quality and distance reduction due to mutual interference of sound waves in complex environments. , directional loudspeakers have been widely used, but in actual use, it is found that the current directional loudspeaker equipment is often complex in structure, has relatively high requirements for the use site, and is relatively difficult to transport and move, and a directional loudspeaker is often only It can meet the single function of sound transmission and environmental noise shielding, ...
