Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-4, a novel air leakage proof speaker 30 comprises a cavity 20, a speaker 30 and a housing 10, wherein a sound cavity hole 21 for embedding and installing the speaker 30 is formed in the cavity 20, a plurality of bolt fixing holes 22 for screwing and fixing are formed in the cavity 20, and a positioning column 23 protruding upwards is formed in the cavity 20, so that a quick positioning effect can be achieved, the upper end of the speaker 30 is clamped in the sound cavity hole 21 of the cavity 20, a gasket 40 is arranged between the speaker 30 and the sound cavity hole 21 of the cavity 20, the gasket 40 is arranged in a structure with a thin middle and a thick edge, so that the gasket 40 can be better placed in the speaker 30 and the cavity 20, and a speaker through hole 41 for allowing the lower end of the speaker 30 to pass through is formed in the center of the gasket 40, so that the speaker 30 can pass through the gasket 40 and be placed on the cavity 20 when being placed in the cavity 20, wherein be equipped with on gasket 40 with the corresponding fixed through hole 42 of bolt fastening hole 22 and reference column 23 on cavity 20, can be convenient for place fast on cavity 20, through be equipped with the open slot 11 that is greater than cavity 20 upper end sound cavity 21 on shell 10, can be more convenient put into shell 10 with cavity 20 to still locate the edge card of gasket 40 in the open slot 11 lateral wall of shell 10, play good compression seal effect.

The gasket 40 is made of Poron foam material in an integrated mode, has high sealing performance, high energy absorption and high buffering performance, has a good environment-friendly effect, and cannot pollute other materials.

The diameter of the gasket 40 is larger than that of the loudspeaker 30, and the edge of the gasket 40 is larger than that of the loudspeaker 30 by at least 1.5mm-3mm, so that the loudspeaker 30 can be placed in the center of the gasket 40, and the loudspeaker 30 cannot touch the cavity 20 to influence sound transmission when vibrating.

The diameter of the gasket 40 is larger than the diameter of the sound cavity hole 21 on the cavity 20, and the edge of the gasket 40 is larger than the edge of the sound cavity hole 21 by at least 1mm-4mm, so that the gasket 40 can be tightly clamped in the side wall of the open slot 11 of the shell 10, a good compression sealing effect is achieved, and the situations of air leakage and the like are prevented.

The cavity 20, the gasket 40 and the speaker 30 are fixed by screws, and the fixing relationship among them can be ensured by the screw connection, and the subsequent maintenance and replacement are convenient.

The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
