Outdoor loudspeaker based on broadcast and movie and television technology

Abstract

The invention discloses an outdoor loudspeaker based on broadcast and movie and television technology, and relates to the technical field of broadcast and movie and television. The outdoor loudspeaker comprises a mounting body, an adjusting mechanism is fixedly mounted at the bottom of the outer surface of the mounting body, and the middle of the outer surface of the mounting body is rotatably connected with the top of the outer surface of a U-shaped plate through a short rod; the middle of the bottom end of the outer surface of the U-shaped plate is welded to the top end of the outer surface of the rotating pipe. Through the arrangement of the first motor, the U-shaped plate and the mounting body and through the mutual cooperative use of the structures, the structures such as the sound amplifying body can rotate by an angle circumferentially, and the sound generator can slowly face different directions, so that the defects caused by fixed mounting can be avoided, and the trouble caused by unclear sound hearing is avoided; therefore, the device can avoid the problem that the sound transmission efficiency is low due to the fact that the direction of the broadcast loudspeaker is fixed, and a plurality of loudspeakers do not need to be installed at the same position, so the efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to an outdoor loudspeaker based on the radio and television technology. Background technique [0002] Loudspeakers are also called loudspeakers. Loudspeakers can be divided into various types according to their size, usage and purpose, and each has its own advantages. Due to the limitation of shape, size and speaker, the general power of portable loudspeaker is only 3--8W. The wireless loudspeaker and the wired loudspeaker are different in size and purpose, and the smaller one is suitable for teachers and tour guides. It can be hung on the waist to make the hands play more freely, and its power is generally 3W-8W. . Larger ones are suitable for outdoor activities, summer camps, extracurricular lectures and other places with a lot of traffic, and the power is between 35W and 95W. Lithium battery amplifiers are one of the classifications based on the type of battery th...
