Embodiment Construction

[0019] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] figure 1 It is a schematic structural diagram of a waterproof sound cavity provided by an embodiment of the present invention, see figure 1 , The waterproof sound cavity includes a panel 10, a waterproof membrane 20, a speaker 30, a pressure plate 40 and a sealing ring 50. The middle of the panel 10 is provided with a first groove 60. The part of the panel 10 where the first groove 60 is provided is provided with a number of small holes 70. The small holes 70 are through holes, that is, at the bottom of the first groove 60 A number of small holes 70. The panel 10 is also provided with an annular second groove surrounding the first groove 60, a sealing ring 50 is arranged in the second groove, and the waterproof membrane 20 is arrange...

Abstract

The invention discloses a waterproof sound cavity, and belongs to the field of audio equipment. The waterproof sound cavity comprises a panel, a waterproof film, a horn, a pressing plate and a sealing ring; a first groove is formed in the middle part of the panel, a plurality of minipores are formed in the part of the panel provided with the first groove, an annular second groove surrounding the first groove is further formed in the panel, the sealing ring is arranged in the second groove, the waterproof film is arranged on one surface provided with the first groove of the panel, meanwhile the waterproof film covers the first groove and the sealing ring at the same time, the waterproof film and the first groove form a first hollow cavity, the pressing plate is arranged above the sealing ring, the waterproof film is located between the pressing plate and the sealing ring, the horn is fixed to the pressing plate, a second hollow cavity is formed among the horn, the pressing plate and the waterproof film, and the output surface of the horn faces to the second hollow cavity. The waterproof level of the waterproof sound cavity can reach IP67, and the sound output effect is not influenced.

Description

Technical field [0001] The invention relates to the field of audio equipment, in particular to a waterproof sound cavity. Background technique [0002] The offshore platform is usually equipped with a broadcasting system, and the terminal of the broadcasting system includes sound cavity equipment responsible for sound output. Due to the harsh marine environment, usually high humidity, high heat, and high salt spray environment, sound cavity equipment needs to be designed and manufactured with waterproof performance. [0003] At present, the waterproof of sound cavity equipment is mainly realized by installing a metal mesh with a high density of gaps. The metal mesh is installed between the panel and the speaker. The mesh number of the metal mesh reaches more than 200 meshes, which has a certain waterproof function. Or, use shielding to prevent rainwater from entering the sound cavity, such as installing a waterproof cover on the outside of the panel. Although the above two waterp...
