Insert part for loudspeaker boxes to achieve a low-vibration housing.

The self-construction of HiFi loudspeaker boxes is a hobby area that is increasing Finds interest.

In recent times, the demands of hobby pit builders have increased in the age of digital technology. This is expressed on the one hand in the demands of the market high-quality loudspeaker chascis, on the other hand in the construction of elaborate loudspeaker housings using special low-vibration materials, which are the The purpose is to prevent disruptive housing resonances in the range of medium and low frequencies to prevent.

This also applies to the industrial production of loudspeaker boxes. While chipboard has mainly been used for the construction of the housing up to now and is still used today, birch plywood and MDF have recently also been used for this purpose (Fibreboard) and occasionally concrete.

Although concrete is particularly low in vibration, it is rarely used because it is only with It takes a lot of effort to process and does not optically match the common living style can be integrated. Mainly wood and lacquered surfaces are preferred here. Another solution, which can also be created for the hobby pit maker, is a double-walled housing filled with sand ((Figure 1), which as the basis of the designed insert is to be seen.

The construction of the double-walled housing (1 outer housing / 1 smaller inner housing) made of Idttenmatetial is very complex and cost-intensive, since practically 4 housings were built for 2 hi-fi loudspeaker boxes.

The proposed solution, while retaining the conventional outer housing, replaces the complex, smaller inner housing with a one-piece / genuine molded part which is glued to the outer housing by a wide edge. The resulting cavity is then filled with sand through appropriate openings (FIG. 2). This is a simpler and more cost-effective solution in terms of manufacturing technology for the inner housing, which, in addition to the field of box construction, is also suitable for the industrial production of hi-fi speaker boxes.
