Description

introduction

The invention relates to the field of public address systems. In particular, the invention relates to a modular housing system for public address systems, which is suitable for interacting with other audio components.

State of the art and disadvantages

Public address systems are used for professional sound reinforcement in the context of music performances, language lectures, multimedia presentations (and similar). Typically, such systems include at least loudspeakers and amplifiers, each with high to very high power (kW range). They are suitable for frequent transport, since they usually do not remain permanently at a place of installation. Due to the high performance and the robustness required by the frequent assembly and disassembly, the components of public address systems are often large and heavy.

PA systems thus differ from home hi-fi systems in several respects, as the latter typically remain permanently in one place, and they are significantly smaller and lighter, since lower powers are sufficient due to the comparatively small room sizes that are to be sounded.

In addition, public address systems in addition to amplifiers and speakers may include other components that are rarely or not used in the home. These are, for example, special monitor speakers, mixers, preamp / power amplifiers, effects units, equalizers, etc. These components are typically supplied in standard 19-inch widths and built into 19-inch racks. On the backs of these racks, the components are electrically connected together, resulting in a variety of cable connections. If a new compilation of these components is necessary, the racks must be re-equipped accordingly and the components are wired, which is always associated with the corresponding effort.

Usually the components of public address systems for each new location are reassembled according to the respective requirements. For this reason, identical components (e.g., loudspeakers) are often provided that then provide the desired acoustic performance through interconnection. Nevertheless, a variety of cables, the supply voltage or signals (audio signals, switching or control signals) must be transported, misplaced and connected correctly. This results in problems such as so-called "trip hazards" due to cables, "loose contacts" due to improperly plugged in connectors, or errors in the wiring due to incorrectly connected connectors, which can often take a long time to detect.

Speaker systems of public address systems as well as home hi-fi systems are typically divided into subwoofer and mid / high speakers. Furthermore, an amplifier can be accommodated in the then serving as a stand housing bassbox (so-called active speaker). From the hi-fi area, solutions are known in which the cabling between the bass speaker and a column-shaped midrange / tweeter speaker is eliminated. The publication WO2010051139 discloses a speaker system in which the bass box has a recess in which a columnar loudspeaker (midrange / tweeter) is receivable. For secure fixing, a rail is provided on the rear side of the columnar loudspeaker which cooperates with a corresponding counterpart in the recess. Thus, the bassbox serves as a holder for the columnar speaker. By means of a mounted on the underside of the columnar speaker contact, which cooperates with a corresponding counterpart, which is attached to the bottom of the recess, the electrical contact between the bassbox and columnar speaker can be produced without cables would have to be plugged.

A disadvantage of this solution, however, is that when changing the orientation of the particular columnar speaker and the bass box must be changed in their orientation. While this is easily possible with light home hi-fi components, moving components of professional sound systems is undesirable due to the higher weights.

In the US design US Pat. No. 4,229,235 p Speakers are shown which group around a round pillar around which they are rotatable. Although in this way a different orientation of speakers and bassbox (not shown) would be possible; However, the construction-technical effort to achieve this rotation is disadvantageous.

Object of the invention and solution

The object of the invention is therefore to avoid the disadvantages of the prior art.

In particular, the invention is the cost of assembling components for Reduce sound systems (wiring, mounting, troubleshooting, ...).

In particular, the invention is also intended to be suitable for supporting columnar loudspeakers in a stand housing, wherein a simple adjustability of the columnar loudspeakers is made possible.

The object is achieved by a modular housing system according to claim 1, a housing set according to claim 8, a columnar loudspeaker according to claim 12, and a columnar electrical component according to claim 16. Further preferred embodiments can be found in the respective subclaims, the following description and the figures.

description

The housing system according to the invention will first be described below. Subsequently, a description will be given of a housing set relating to specific embodiments of the housing system, namely, the advantageous mounting of columnar loudspeakers or columnar electrical components in a pedestal housing.

The modular housing system according to the invention relates to the field of professional sound systems (PA systems). It comprises at least two core elements.

A first core element relates to a base plate having electrical inputs and / or outputs for supply voltage (ie power) and / or signal-carrying lines for connecting the base plate to external electrical components.

The base plate is thus suitable to be used as an electrical "adapter plate" in which it provides some or all of the necessary for the operation of a public address system connections to the outside. External electrical components are, for example, external amplifiers, mixing consoles or playback devices. By definition, the power grid is also considered such an electrical component. Preferably, the base plate has a thickness that is significantly less than the width and length of the plate (e.g., 1, 2, 3 or 4 cm). The thickness can also be 44.45 mm. More preferably, the base plate has a footprint equal to or greater than that of a 19 inch rack by a few centimeters. The electrical inputs and / or outputs are preferably located at the rear thereof, and more preferably in a recess therein, so that inflexible cable ends extend within this recess where they are protected.

The other base element relates to a housing for at least one electrical component of a public address system. Suitable components are all components mentioned above, also in the introduction. Preferably, the housing has an internal dimension which corresponds to the inside dimension of a known 19-inch rack, wherein the inner height is based on the so-called "rack units" (RU, dt. "Height units", HE), and for example 5 RU or 10 RU (1RU = 1.75 inches = 44.45 mm). In this respect, the housing initially fulfills the function of a known rack, wherein one or more electrical components can be accommodated in a housing.

It is further provided that within the base plate at least one of the inputs and / or outputs is electrically connected to at least one arranged at the top of the base plate electrical contact. For this purpose, one or more electrical lines are laid within the base plate. It is also possible that at least one of the inputs and / or outputs is branched or merged, and that inputs and outputs are in direct connection with each other (e.g., looping through signals).

The electrical contact is in turn adapted to cooperate with at least one corresponding to the underside of the housing arranged electrical "complementary" contact. The interaction is at least positive, and may possibly be supported by spring force and / or magnetic force. Such connectors are known from the prior art and have the advantage that they require no additional mechanical Verrieglung. Examples include the known from electric kettles ago connectors, or known from computer technology magnetically-assisted couplings for power supplies of portable computers.

This (complementary) contact in turn is connectable within the housing with the at least one electrical component. Thus, at least one of the electrical connections is no longer (or not only) accessible via the back of the component but via the complementary contact. This can be, for example, the supply voltage. It can also be, for example, an audio or control signal. Of course, a plurality of terminals can be connected to a plurality of electrical contacts of the component.

In this way, therefore, at least one pair of contacts, comprising at the top of the Base plate and arranged on the underside of the housing electrical contact formed.

The housing can be turned off on the base plate, so that at least one of the inputs and / or outputs of the base plate can be electrically connected to the housing and thus the electrical component accommodatable therein by means of the contact pair. In this connection, it is clear that the above-mentioned "suitability for cooperation" of the contacts is only possible if they match each other geometrically, and are also arranged at complementary positions on the base plate or under the housing. In other words, both contacts of the respective contact pair must be positioned one above the other when viewed in the vertical direction when the housing is placed on the base plate.

Thus, the invention reduces the cost of assembling components for public address systems (wiring, mounting) significantly. By simply stacking a case over the base plate, some or all of the major cable connections between these components are made without the need for manual cabling. Only a one-time cabling of the base plate with external components is required. This is particularly advantageous if, as will be shown later, several of the housings form a stack which is placed on a single base plate. If all relevant electrical connections are covered by means of corresponding pairs of contacts, the back of the housing or the housing can be closed, which is advantageous in terms of safety, but also aesthetic aspects. An accidental wrong wiring is prevented. The connections are protected so that the risk of damage or injury is reduced. Since simple stacking is significantly faster than the installation of "bare" components in racks, time is saved in building a newly assembled public address system.

According to a preferred embodiment supply voltage-transmitting contacts and signal-transmitting contacts are distinguishable from each other by a specific placement and / or by a positive coding of a pair of contacts.

"Specific placement" means that, for example, the contact pairs for the supply voltage are always arranged in the center of the elements, and, for example, signal-carrying contacts (audio signal) in a specific corner. In the case of stereo sound systems, for example, the contact pair for the right channel can run in the front right corner, and the contact pair for the left channel in the front left corner.

"Form-fitting coding" means that - despite possibly identical placement of supply voltage transmitting and signal transmitting contacts (seen from above, for example in the center of the elements) - only those contacts are suitable for interaction, either supply voltage transmitting or signal transmitting. This can be achieved for example by different geometrical configurations; so supply voltage-transmitting contacts round, and signal-transmitting contacts can be configured angular. In the case of identically constructed pairs of contacts projections or depressions may be arranged on the (mechanical) contact surfaces of the base plate and housing, which only then positively engage each other and thus allow the shutdown of the elements to each other, if characterized by a contact pair of the same type (either supply voltage transmitting or signal transmitting contact pair) forms. Preferably, such a geometric coding is well visually recognizable, for example by four of the projections or depressions described are arranged around the actual contact pair around, in which case a square, and in the other case forms a rhombus. If these projections or depressions are arranged in the vicinity of the contact pair, and if mismatched elements are placed on top of each other, the user already recognizes, due to the strong wobbling, that there is a misplacement.

According to a preferred embodiment, the at least one contact pair is designed as a concentric plug connection. Such connectors are known from the prior art, for example, electric kettles in which also by simply turning off the stove (housing) on the base (base plate) an electrical contact of these elements is made without each time a power plug are plugged into the stove would. This remains rather permanently in the base. It is clear that such a connector should be designed to be safe to touch to avoid electric shock; at least if it is intended for supply voltages. The contact reliability is preferably ensured both with supply voltages and with loudspeaker signals which may well have health-endangering voltages and / or current intensities.

An advantage of the concentric plug connection is that the elements connected to it are, in principle, rotatable relative to one another without losing the electrical contact. This will be discussed later.

According to a preferred embodiment, the housing further also on its Top side at least one electrical contact of a contact pair according to the above definition, and it is adapted to carry a further housing. This further housing now has at least on its underside (and optionally likewise on its upper side) at least one correspondingly arranged contact of a contact pair.

With such housings thus already above several times mentioned stack can be formed, wherein the electrical contact is made possible by means of said contact pairs not only between the base plate and the bottom housing, but also this and above it stacked housings.

Optionally, the housing is arranged for supply voltage and / or signal transmission between the contacts arranged on its underside and its upper side. Thus, in particular signals or supply voltages which are not processed or required in a specific housing can be supplied to a further housing stacked above, which then either further processes these signals or supply voltages themselves or, if necessary, loop them further upwards.

Preferably, base plate and housing have the same base area. As already mentioned above, the base area of a 19-inch rack is particularly preferably used for this purpose. Possibly. the footprint of the base plate is slightly larger, for example, to further increase stability, or to provide space for, for example, on the rear side of the inputs and / or outputs, which would otherwise be obscured by a housing stacked on the base plate ,

According to another embodiment, the base plate may also have, for example, two or three times the width of the housing in order to be able to build up correspondingly larger stacks without having to repeatedly connect the inputs and outputs with external components.

According to a further embodiment, the housing system further comprises a cover plate arranged for positive storage on the at least one housing, which has in its underside at least one recess for the possibly arranged on the top of the housing at least one contact. Such a cover plate therefore serves the protection of the uppermost housing from external influences and at the same time the protection of the user from contact with the contacts, provided that they are present at the top of the uppermost housing and not sufficiently finger-safe. In addition, this achieves a shapely appearance. Finally, so are other, not part of the invention devices on the stack off without colliding with any existing projections.

The invention also relates to a housing set for a modular housing system according to the above definition for supporting at least one columnar loudspeaker, or a compatible columnar electrical component.

"Housing set" means that for this purpose, two of the elements must be coordinated in a special way to each other to fulfill the task.

The "columnar loudspeaker" may comprise one or more sound transducers, in particular midrange and tweeter loudspeakers. He can, as will be shown later, be modular in turn. In this way, a particularly flexible structure, suitable for the particular sound situation, possible.

The first element of such a housing set is a housing which can be used as a stand housing, wherein this housing is otherwise preferably designed in accordance with the above definition (dimensions, contact pairs, etc.). This housing, which is now referred to as a "stand housing", additionally has a vertical, optionally also slightly tilted, recess arranged in the edge region for the positive reception of at least the lower part of the columnar loudspeaker or the columnar electrical component.

Second element is a base plate, which is preferably also designed according to the above definition. However, this base plate has a (then additional) electrical connector for contacting the columnar loudspeaker or the columnar electrical component with the base plate.

According to the invention, the recess in the housing is now formed by extrusion of a (at least 2-fold) rotationally or rotationally symmetrical base along an axis of rotation, and at least the lower part of the columnar loudspeaker intended for positive engagement is formed by extrusion of a rotationally or rotationally symmetrical basic shape.

In order to be able to differentiate the two forms (recess in the housing of the housing and extrusion of the lower part of the columnar loudspeaker), the term "base surface" or "basic shape" has been used here.

"Rotationally symmetric" (also called "radial symmetry") means that the respective geometry, rotated around a fulcrum (area centroid), is mapped onto itself again. For example, a twofold rotational symmetry has a rectangle, a threefold isosceles triangle, a fourfold a square, a fivefold, a regular five-armed star, and so on. A special case is the rotational symmetry (corresponding to an "infinite" rotational symmetry).

According to the invention also the connector is designed as a rotationally or rotationally symmetrical contact pair and arranged after assembly of the housing and base plate coaxially with said rotation axis on top of the base plate. Reference is made to the above statements on the subject of "contact pair".

The base surface on the one hand and the basic shape on the other hand must also be coordinated so that the columnar speaker with its lower part is inserted into the recess. This condition is fulfilled, for example, if the base area is larger than, but otherwise similar to, the basic shape (for example, a small, five-fold basic shape in a larger, five-fold base area). However, it is also satisfied if the "countness" of the base is an integral multiple of the "count" basic form (e.g., three-digit basic form in a six-count base). It is also satisfied, for example, if the envelope of the basic shape is so small that it has space at all times (ie independent of the angle of rotation) in the base area.

As a result, the lower part of the columnar loudspeaker can thus be held in a form-fitting manner within the recess in different angular positions. For example, in a hexagonal rotational symmetry, holding positions exist at 0, 60, 120, 180, 240, and 300 degrees.

Due to the rotationally or even rotationally symmetrical plug connection, it is ensured that the columnar loudspeaker can be electrically contacted by the base plate by means of a contact arranged centrally on its underside, irrespective of the angle of rotation. Thus, here also eliminates the manual insertion of cables, and the columnar speaker can be easily brought into different orientations, which depend concretely on the geometry of the recess and base. By contrast, different alignments are not known from the constructions known from the prior art (see introduction).

Such a construction makes it possible to support a column-shaped loudspeaker in a stand housing, with easy alignment of the columnar loudspeakers being possible. The stand housing itself does not have to be moved, as is known from the prior art, which is a great advantage with regard to the large weights of professional sound systems. Turning the columnar speaker through 180 ° turns a "normal" speaker into a "monitor speaker" that populates musicians on stage. Even a fine adjustment of the sound on the orientation of the columnar loudspeaker is possible without effort. In principle, even an electric drive is conceivable, which allows the adjustment by remote control, or which allows the sound direction of a group of people follows.

Another advantage of the construction according to the invention is the absence of rails or the like, which are required for a secure support in constructions of the prior art.

According to a preferred embodiment, the base of the recess is circular, so that there is a cylindrical recess. Such a shape is particularly easy to produce, and it has the advantage that the columnar loudspeaker is continuously rotatable in this recess. It is clear that the envelope of the basic shape must be slightly (but not significantly) smaller than the inner diameter of the recess in order to achieve a good fit.

According to a further preferred embodiment, the recess is arranged such that the axis of rotation (= extrusion axis) extends within the pedestal housing. In other words, the imaginary lateral surface of the recess extends more than 50% and less than 100% inside the housing.

This means that the position of the recess is not at any point in the edge region of the pedestal housing, but that the recess "cuts" the outer surface of the pedestal housing, resulting in a more or less wide, vertical slot in this outer surface, through which one in the Recess can look into it. However, so that the columnar loudspeaker is held securely, the widest point of the recess must still lie just inside the stationary housing, otherwise the columnar speaker could tip out. Advantageously are o.g. Values between 60% and 85%, for example, are 78.4%.

This construction has the advantage that the columnar loudspeaker can also be equipped with sound transducers in the region of its lower part, which would otherwise be concealed by the inner wall of the recess. Is the recess slightly backwards tilted, the center of gravity of the housing set is moved back into the center by advancing the axis of rotation, which increases the stability.

This is also advantageous if the stand housing is provided for holding a plurality of column-shaped loudspeakers by means of a plurality of recesses arranged in the edge region of the pedestal housing. For example, two stereo speakers can be set to right and left in the floor-standing cabinet, or three or more columnar speakers can be used to achieve 360-degree sound.

It is clear that the base plate then in each case at the corresponding locations, which are located below the recesses in the housing stand, holds appropriate contacts. Alternatively, however, in such cases, a manual wiring of the optional further columnar speakers can be done.

It is also possible that different speaker types have a different basic shape, and so can only be used in accordance with this type suitable recesses. For example, columnar loudspeakers with midrange speakers may have a different basic shape than those with tweeters.

The housing set described above comprises in addition to the columnar speaker, the base plate and the housing stand.

According to a particular embodiment, the functionality of the base plate and the housing stand is combined in one element. This is advantageous if the other functionalities are not needed, so if, for example, a stand housing with bassbox and amplifier, as well as set columnar speaker to be operated as a "stand-alone" device.

Accordingly, such an "integrated stand housing" a arranged in the edge region of the pedestal housing vertical (possibly slightly tilted) recess for positive reception of at least the lower part of the columnar loudspeaker, and also is an electrical connector for contacting the columnar loudspeaker with the housing, which provided in the region of the recess (and not in the area of the basic shape of a base plate, see above).

Recess of the pedestal housing and lower part of the columnar loudspeaker are again formed by extrusion of a rotationally or rotationally symmetrical base surface or basic shape.

The connector is also designed as a rotationally or rotationally symmetrical contact pair and arranged coaxially with said rotation axis on the base (and not on the top of a base plate). In other words, the recess is not continuous, but has (similar to a blind hole) on a recess base, which coincides with the base, in the center of which the corresponding electrical contact is arranged.

The columnar loudspeaker is thus directly from the housing stand (and not from a base plate) electrically contacted. Thus, according to this particular embodiment, the separate base plate becomes obsolete or is integrated with the standing case.

Incidentally, the said in the context of the housing set described above, so that can be dispensed with repetitions.

The invention also relates to a pillar-shaped loudspeaker for a stand housing, as described above. It is clear that this only has to be formed at its lower part so as to be insertable into the corresponding recess. However, it is preferably of the same cross-section throughout. For this example, aluminum profiles are advantageously used.

The columnar loudspeaker preferably has a circular basic shape and optional flattenings running on a front surface. The circular basic shape leads to a particularly easy to produce profile, and the flats allow easy installation of the transducer typically present in plurality. In addition, the round basic shape allows a continuous rotation of the columnar loudspeaker in the recess.

According to a preferred embodiment, the columnar loudspeaker also has on its upper side an electrical contact according to the above definition, so that a plurality of columnar loudspeakers are stackable and simultaneously electrically contactable with each other by means of corresponding pairs of contacts.

Since the same types of contacts are always used, compilations can be formed in the simplest way that best suit the respective boundary conditions.

Via built-in crossovers in the individual segments of a total column crossovers can be operated correctly by means of a looped through the entire column signal and different transducers.

If several columnar loudspeakers are to be stacked one above the other, a mechanically stable connectivity is desirable. This can be achieved for example by means of a bayonet coupling. By inserting a new segment and turning it, the bayonet catch engages and secures the segment against loosening. Possibly. is a placement and locking in several angular positions possible so that overall columns can be produced with segments of different orientation.

Optionally, the surface on which the lowermost segment is turned off (upper side of the correspondingly suitable base plate) can also have such a closure possibility, or at least recesses, which could lead to a wobbling due to non-engaging connection geometries. Alternatively, protrusions of such geometries may each face upwards so that the bottoms of the segments are substantially planar and only have contact as protruding geometry.

Optionally, a columnar loudspeaker also includes a cover that covers any existing, upwardly facing contacts. This protects the contacts and leads to a more aesthetic appearance of the overall columns.

for a pedestal housing, as described above. It is therefore clear that columnar columnar columnar. Preferably, the pillar-shaped pillar of light, as a fragrance column, or as a nebulizer column is formed column-shaped columnar columnar columnar [adapter] columnar It may happen that a columnar loudspeaker is to be applied to a housing, which is not a standing housing, wherein the holder is to be effected by a further stand housing according to the above definition (housing with a continuous recess). Since no base plate for direct contacting of the underside of the columnar loudspeaker is available here, the housing arranged below the supporting housing must provide this functionality.

This is achieved by the housing for electrical contacting of a columnar loudspeaker in the edge region of its upper side has an electrical contact of a contact pair, so that the columnar loudspeaker is electrically contacted, if it from the recess of a pedestal housing from a housing set as defined above (with a continuous recess ), which is placed on the housing is held.

In other words, the housing located below the pedestal housing, at the point at which the recess of the pedestal housing adjacent to the underlying housing, on the contact for contacting the columnar loudspeaker on.

Thus, on a base plate one or more housings such as e.g. Preamp and power amplifier be set up. The power amplifier housing provides the contact for the columnar speaker, and on the power amplifier housing a pedestal housing is stacked, in which, for example, a bass box is located, and in the recess of the columnar speaker is supported. It is clear that what has been said is also valid analogously for a columnar electrical component.

In the 1 is a first embodiment 11 a housing according to the invention 10 shown.

The housing 10 . 11 is for receiving at least one electrical component (not shown) of a public address system (not shown). At the bottom of the case 15 (not visible) is an electrical contact 19 (not visible), which is inside the housing 10 . 11 can be connected to the electrical component (connections not shown).

In the 2 is a first embodiment 21 a base plate according to the invention 20 shown. This one has at the back 25 electrical inputs and / or outputs (not visible) for supply voltage and / or signal-carrying lines for connecting the base plate 20 . 21 with external electrical components (not shown).

Inside the base plate 20 . 21 At least one of the inputs and / or outputs is electrically connected to one at the top 26 the base plate arranged electrical contact 29 connected (connection not visible). This contact 29 is in turn to interact with the at the bottom 15 of the housing 10 . 11 arranged contact 19 set up.

This way is a contact pair 19 . 29 educated. Because the case 10 . 11 on the base plate 20 . 21 is turned off, in this way at least one of the inputs and / or outputs by means of the contact pair 19 . 29 electrically connected to the housing.

By a specific placement and by a positive coding of a contact pair 19 . 29 are supply voltage transmitting contacts and signal transmitting contacts distinguishable from each other. Present is the base plate 20 . 21 a supply voltage transmitting contact 29 ready. This is in the center of the base plate 20 . 21 arranged, which has an approximately square basic shape. By arrangement of four formations 27 (only one provided with reference numerals) at the top 26 the base plate 20 . 21 in the form of a rhombus, and by providing appropriately arranged and sized recesses (not visible) in the bottom 15 of the housing 10 . 11 ensures that only matching connection types are contactable with each other.

Like from the 1 and 2 the contact pair is visible 19 . 29 designed as a concentric connector. Such connectors that contact only by juxtaposing the elements comprising these contacts, for example, in the application of the number EP 0719464 A1 from the company STRIX LTD, UK. Advantageous is the independence of the angular offset between the male and female part of the plug, which will be discussed later.

This in 1 shown housing 10 . 11 also has on its top 16 an electrical contact 18 on the type of contact pair described above. In addition, the housing 10 . 11 also adapted for carrying a further housing (not shown), which then at least on its underside 15 at least one appropriately arranged contact 19 a contact pair must have, so that a stacking of the two housings is made possible while simultaneously contacting the corresponding contact pair.

To ensure easy stacking, have base plate 20 . 21 and housing 10 . 11 the same footprint on. This can for example be 53 × 53 cm.

In the 3 is a second embodiment of a housing according to the invention 10 shown, which as a stand housing 12 is usable for a columnar speaker or a columnar electrical component (not shown), and which has a low height (eg 27.5 cm).

In the stand housing 12 By way of example, two sound transducers (in the present case 2 × 8 inch subwoofer, not shown) can be installed. As can also be seen, it has at its top 16 a contact 18 on. The contact lying on its underside 19 is not visible.

In contrast to the housing described above 10 . 11 is the contact 15 presently provided for signal transmission. Therefore, its positive coding differs from that described above in that the four formations 27 (Only one provided with reference numerals) form a square, which at the outer edges of the pedestal housing 10 . 12 is aligned. This applies in an identical way to those at its bottom 15 located recesses (not visible).

Main difference to the housing described above is a recess 17 located in the front edge area of the stand housing 10 . 12 is located and continuous (top and bottom open) and circular designed. In this recess 17 is the positive reception of at least the lower part of a columnar loudspeaker or a columnar electrical component (not shown) possible. It is clear that the columnar loudspeaker must have a corresponding, preferably likewise circular cross-section, in order to be able to be accommodated in a form-fitting manner.

In this case, the axis of rotation R, along which the recess 17 can be produced by extrusion, in a plan view still within the envelope of the pedestal housing 10 . 12 placed; However, their measured in the horizontal direction distance to the nearest outer edge is not more than the radius of the recess 17 , Thus, a part of the (imaginary) lateral surface of the cylinder, which is the wall of the recess 17 forms outside the stand housing 10 . 12 , In this way, a vertically extending access or slot is provided, which can serve, for example, to make otherwise hidden sound transducer of a columnar loudspeaker visible. In addition, a column-shaped speaker moves even further from the center of the stand housing 10 . 12 at the edge, leaving more space inside for electrical components.

The 4 shows a stand housing 10 . 13 , which is a variant of the prior case described above 10 . 12 is, and that has a large height (eg 53 cm). By way of example, this is suitable for accommodating a large bass loudspeaker (1 × 15 inches, not shown). For reasons of clarity, further, already introduced reference numerals have been omitted. Also the stand housing 10 . 13 has the said recess 17 on.

To make electrical contact with a columnar loudspeaker is according to 5 a second embodiment 22 a base plate according to the invention 20 shown, which cooperate with a stand housing according to 3 or 4 (with continuously open recess 17 ) suitable is.

This base plate 22 has, in contrast to the embodiment shown above, an additional contact 29B on. This is arranged in the region of the front side, and thus runs collinear with the axis of rotation R of the recess 17 a stand housing 12 . 13 if this on the base plate 22 is turned off. In this way, a columnar loudspeaker or a pillar-shaped electrical component, which is supported by the stator housing, and which has a respective mating contact on its underside, can be electrically contacted without having to manually plug in cables.

If the base of the recess is also round, as in 3 and 4 shown, the columnar speaker or the columnar electrical component can be rotated 360 degrees, without the risk of pinching the cable would be. He or she can be easily rotated in any position, without the stand housing 12 . 13 or the base plate 22 would have to be rotated. It is clear that for this purpose a rotationally symmetrical contact connection (see above) must be used.

In the 6 is a third embodiment of a housing according to the invention 10 shown, which cooperates with a stand housing according to 3 or 4 suitable is.

It is different from the one in 1 shown housing 10 . 11 especially because it - analogous to the in 5 described base plate 22 - one in the area of the front on the top 16 arranged contact 29 which also has the same functionality as in said base plate 22 Has.

In the case 14 An electrical component (not shown) can be accommodated (eg amplifier, mixer, loudspeaker). It also serves as a contactor for a columnar loudspeaker or a columnar electrical component (not shown) whose underside contact with the contact 29B interacts.

An exploded view of a base plate assembly 21 according to 2 , a housing 14 according to 6 , and a stand housing 12 according to 3 is in the 7 shown. From this view, it is easy to see how the elements work together to provide a sound system that can be put together in just a few steps. While the base plate 21 the supply voltage for the housing 14 supplies and has a corresponding coded contact, operates the housing 14 via a different coded contact signals for the columnar speaker (not shown) and possibly further, on the housing 12 removable housing (not shown).

The 8th finally shows a frontal view of an assembly according to 7 in which also the column-shaped loudspeaker supported by the stand housing 30 is shown. In the embodiment shown, this comprises the actual sound converter part 31 and a pedestal located thereunder 32 , The latter comprises a lower part, which positively in the recess of the pedestal housing 12 is included.

Below the stand housing 12 is a housing 14 arranged, which is the bottom of the columnar loudspeaker 30 contacted. The lowest element is the base plate 21 which provides the supply voltage. For clarity, all contacts are shown without reference numerals.

To ensure the greatest possible flexibility is the base 32 from the sound converter part 31 removable and in turn has corresponding (matching) contacts on its top and bottom, so that the signal of the housing 14 to the sound converter part 31 can be looped through, without having to lay cables. Would instead of the socket 32 another Schallwandlerteil be installed, the two Schallwandlerteile could have different orientations, which is advantageous in optimizing the sound of PA systems.

As conclusion is on the Schallwandlerteil 31 another cover 33 , This is suitable to the at the top of the sound transducer 31 to receive arranged contact (without reference numeral) and also to cover.

Not shown are optional mechanical fasteners, the sound transducer 31 , Pedestal 32 , Cover 33 with each other and / or with the housing 14 connect, and which may preferably be designed in the manner of a bayonet closure.

In the 9 schematically different positions of the rotation axis R in the housing stand (dotted area) are shown. In a plan view, the thick solid line represents the front side housing edge. The circles represent the base of the recess 17 (reference number shown only once). The small cross symbolizes the position of the rotation axis R (reference number shown only once).

On the left in the picture is the recess 17 completely in the housing. In addition, the case is shown in which the recess 17 just the front of the stand housing cuts; the distance of the axis of rotation R of the stationary housing edge just corresponds to the radius of the circle, the base of the recess 17 forms. Right next to the case is shown, which is also in the 3 and 4 finds. The lateral surface of the (imaginary) cylinder, the recess 17 is partially disposed outside the front, but the widest point of the recess 17 is still inside the stand housing. Thus, one in the recess 17 set column-shaped speaker do not tilt out of this.

Only the far right in the picture shows the case in which the axis of rotation R lies outside the stationary housing, and this is to be avoided because the columnar loudspeaker can no longer be held in the housing of the stand without further aids (for example rails on its rear side).

As shown, the invention solves the tasks placed on it. It effectively reduces the overhead of assembling components for public address systems, as at least partially eliminates cabling between the components, and no more mounting the same in a rack is required. Rather, the components are joined by simply stacking the components once installed in housings according to the invention.

The invention is also suitable for supporting columnar loudspeakers in a housing according to the invention designed as a standing housing, with easy alignment of the columnar loudspeakers being possible.

Due to the modular design of all elements, new compilations can be provided quickly and easily; Even the short-term exchange of individual components is safe and quick to carry out, which is particularly in view of the limited possibilities immediately before and during events of great advantage.
