Rainproof composite sound box

Abstract

The invention discloses a rainproof composite sound box, and the sound box comprises a rainproof box, a frequency divider, a waterproof low-sound loudspeaker, a horn loudspeaker and a waterproof mesh, wherein the frequency divider is arranged inside the rainproof box, the waterproof low-sound loudspeaker, the horn loudspeaker and the waterproof mesh are respectively installed on the rainproof box; the waterproof low-sound loudspeaker is located below the horn loudspeaker, the frequency divider is electrically connected with the waterproof low-sound loudspeaker and the horn loudspeaker; the PVC (polyvinyl chloride) waterproof box is provided with a rainproof socket electrically connected with the frequency divider, the rainproof box is formed by assembling the rainproof composite plates, and the rainproof composite plates comprise PVC plate layers and wooden plate layers on the PVC plate layers. The rainproof composite sound box has the advantages of simple structure, low cost, and good rainproof effect, besides, its tone quality is superior to that of the mold sound box, thus the rainproof composite sound box is suitable for promotion and use.

Description

technical field [0001] The invention relates to a rainproof audio system, in particular to a rainproof composite audio system. Background technique [0002] Existing speakers have the following forms: [0003] 1. Wooden speaker [0004] Wooden speakers are generally made of laminated boards, plywood, and particle boards. Although the sound quality of wooden speakers is good, it is difficult to solve the problem of rainproof cabinets. Generally, it is solved by very complicated processes, such as: soaking wooden boards in antiseptic solution, soaking and spraying paint for many times after the box is formed. The disadvantage is that the process is complicated, the cost is high, and it is labor-intensive and time-consuming. Even if the audio box is made through the above process, it is still difficult to ensure that the speaker box is cracked, peeled off paint, degummed, water ingress and damp due to thermal expansion and contraction, repeated drying and wetting after being...

AI Technical Summary

Problems solved by technology

However, the first mold-making cost of aluminum alloy speakers is high, and currently there are only small-diameter, small-speaker, and low-power sound columns; because the box body is made of metal sheets, the sound quality of the speakers is difficult to improve

Plastic speakers can be installed with large-diameter and high-power speakers, but the cost of the first mold opening is high; the cabinet is thin, prone to box vibration, and the sound quality is difficult to improve

FRP speakers can be installed with large-diameter and high-power speakers, but the cost of the first mold opening is high, the production process is complicated, the production cost is high, the workmanship is poor, the aesthetics are poor, and the sound quality is difficult to control
