Abstract

A loudspeaker box produced by a casting method having a body (1) with at least one first opening (3) for inserting a loudspeaker unit (6) and a second opening (4) with a channel-shaped internal extension (5) integrated in the body (1) for generating a bass reflex effect.

Description

The present innovation relates to a speaker.

Such boxes are known in many embodiments. They are usually assembled from plate-shaped components made of suitable materials, in particular wood or plastic. In this case, corresponding openings for insertion of the respective speaker units are provided. Furthermore, it is known in such loudspeaker boxes to provide appropriate measures for generating bass reflex effects and also to form suitable openings in the body of the loudspeaker box.

The present innovation has the object to provide a speaker that is characterized by a particularly massive design.

This object is achieved according to the innovation by a loudspeaker box produced by a casting method, which comprises a body with at least one first opening for insertion of a loudspeaker unit and second opening with a channel-shaped internal extension integrated in the carcass in order to produce a bass reflex effect.

The body of the renewal trained loudspeaker box is produced by a casting process, so that there is a particularly solid designed speaker. The body can be cast as a one-piece body, or it can be assembled from several cast parts. For molding the body or its parts find appropriate forms use, wherein one or more inner and outer molds can be used. For example, a loss form can be used as inner form, for example made of polystyrene foam. Outer forms may preferably be reusable. Incidentally, known casting methods can be used for producing the body.

When the loudspeaker box is assembled from several cast parts, these are joined together in particular by gluing or by screws.

Concrete is preferably used as the material for producing the loudspeaker, so that the desired solid construction is achieved. Other suitable casting materials may also be used if the desired solid design is achieved.

An essential feature of the rebuilt loudspeaker box is that it has a channel-shaped internal extension integrated in its body for generating a bass reflex effect. This channel-shaped internal extension is co-molded in the manufacture of the one-piece body, i. H. integrated directly in the manufacture of the body in these. If the body is assembled from several cast parts, the internal channel-shaped extension is poured together with the associated components (wall components) of the body, so that also in this approach, the necessary for exploiting the bass reflex effect opening, including channel-shaped internal extension is made by casting.

In any case, therefore, the bass reflex channel of a low-vibration material, which is used for casting, such as concrete.

In any case, a particularly massive visual impression is achieved.

The channel-shaped internal extension can have various geometric shapes. The bass reflex channel can thus be square or round. In a preferred embodiment, the channel-shaped internal extension is triangular in cross-section. The associated second opening in the body is therefore preferably designed triangular in this embodiment. Other opening shapes may depend on the intended channel cross-section.

In another particular embodiment, the channel-shaped internal extension may taper inwardly. This can result in a cross-section of the channel which increases from the inside to the outside. Of course, the channel can also have a constant cross-section.

The renewal trained speaker box may further comprise a wooden front panel. Such front panels may also consist of other materials, for example suitable plastics. They are suitably fastened to the cast body of the loudspeaker box, for example by gluing.

It is understood that the speaker is also designed to accommodate other electrical or electronic components, in particular for the arrangement of coils, resistors, capacitors, crossovers and connection terminals. It is also possible to integrate an amplifier to form an active loudspeaker box.

The innovation will now be explained with reference to an embodiment in conjunction with the accompanying drawings in detail. Show it:

1 a spatial view of a speaker;

2 a spatial view like 1 with dashed internal training; and

3 a side view of the speaker of the 1 and 2 with dashed speaker unit.

In the 1 illustrated speaker has a body made by pouring concrete body 1 in the shape of a cuboid. The body is on the front 1 a front panel 2 wooden. In the front panel 2 and in the corresponding wall of the cuboid is an opening 3 provided for receiving or inserting a speaker unit.

Further, in a side wall of the body 1 in the lower right corner as shown another opening 4 provided, which is triangular in shape. At this opening 4 closes inside a channel-shaped internal extension 5 at. The channel-shaped internal extension 5 as well as the opening 4 serve to create a bass reflex effect. Here is the internal channel-shaped extension 5 in the body 1 the speaker box integrated and poured in the casting of the carcass.

2 shows the internal structure of the body 1 the speaker box. One recognizes the cross-sectionally triangular shaped bass reflex channel 5 in the triangular opening formed in the side wall 4 ends. Further, the opening 3 to record the speaker unit, here at 6 is indicated.

3 shows the speaker in the side view. The in the opening 3 used speaker unit 6 is shown schematically. The front panel 2 closes the body 1 the speaker to the front or off there is attached to a corresponding front wall of the body. The triangular opening 4 with internal channel-shaped extension 5 is located in the lower right corner of the sidewall.

The body 1 the speaker box including the internal channel-shaped extension 5 is made of concrete and is made by casting using suitable internal and external molds. Since thus also the bass reflex channel 5 Concrete, ie a low-vibration material consists, are achieved in addition to the advantages of a solid construction corresponding sound technical advantages.
