Weatherproof constant pressure linear array sound device

Abstract

The invention discloses a weatherproof constant pressure linear array sound device. The weather proof constant pressure linear array sound device adopts a fixed structure member and a series connection fastener which fix and connect a plurality of adjacent water tanks in series; numbers of waterproof sound box assemblies can be customized; the number of the waterproof boxes can be fast increased and reduced in order to applicable to various application scenes; the waterproof sound box assembly comprises waterproof cloth, a waterproof ring, a waterproof loudspeaker, a waterproof plug-in connection seat and a waterproof connection line and thus a professional waterproof capability is guaranteed; and, particularly, the plurality of waterproof sound boxes are in circuit connection through the waterproof plug-in connection seat and the waterproof connection wire. The weatherproof constant pressure linear array sound device cannot only work all day, but also can improve sound intensity of a sound post and sound directive; a passive sound intensity display assembly can emit visible light with different intensity and prompts the user about the current sound intensity of the sound post; when voltage exceeds a threshold, visible light in different color is displayed as an alarm; the passive sound intensity display assembly can quickly determine faults of a voltage drop transformer, the passive sound intensity display assembly and the waterproof sound box.

Description

technical field [0001] The invention relates to the field of sound reinforcement, in particular to an all-weather constant pressure linear array sound system. Background technique [0002] With the development of the economy and the needs of national cultural construction, the broadcasting system has been more and more widely used, such as: many large-scale sports games, large-scale outdoor theatrical performances, etc. [0003] In these occasions, traditional sound columns or line array speakers are generally used in the industry for sound transmission. The traditional sound column refers to a columnar speaker with multiple speaker units vertically arranged in the same cavity, usually a metal shell; a linear array speaker is a combination of several individual professional speakers, usually an active speaker, and the shell is mostly wood. [0004] However, there are following disadvantages in the way of sound amplification. [0005] 1. The number of speaker units in a tra...

AI Technical Summary

Problems solved by technology

[0005] 1. The number of speaker units in a traditional sound column is fixed and cannot be increased or decreased at any time according to different scenarios

[0006] 2. The linear array speakers are not waterproof and the cost is relatively high

[0007] 3. It is impossible to know the sound intensity of the speaker through vision

[0008] 4. Unable to judge the fault point, it is inconvenient to troubleshoot
