Definitions

  • the invention relates to a loudspeaker arrangement in which the sound is conducted from at least one loudspeaker or another sound source via sound guiding rooms to sound outlet openings.
  • Such a loudspeaker arrangement in particular as a loudspeaker box, is known in different designs.
  • Such a loudspeaker arrangement can be equipped with several loudspeakers, preferably with different frequency behavior, such as high-frequency loudspeakers and low-frequency loudspeakers.
  • loudspeaker arrangements the sound is emitted at a more or less narrow angle, so that the impression of a relatively concentrated sound source is created.
  • two such loudspeaker arrangements are arranged at a certain distance from one another and are controlled with different signals.
  • the invention has for its object to provide a universal hi-fi detour loudspeaker arrangement, which is housed in a more or less compact housing and with its special properties is a universal hi-fi sound diversion box, which is suitable for creating room sounds and / or reproducing rooms as well as for particularly plastic and natural sound reproduction up to artificial head reproduction in all areas and thus represents a unique and unmistakable universal hi-fi sound diversion box is independent of space.
  • the loudspeaker (s), viewed in the direction of sound emission, are arranged opposite at least one sound-guiding surface, which distributes and deflects the sound approximately evenly, of a partial section of a cylinder, a sphere or two, preferably flat, sound-guiding surfaces are bow-like inclined towards each other at an obtuse angle and on or between which, with or without a fixed connection, geometric bodies can be placed or inserted, the lying approximately in the middle of the height or width of the sound guide surfaces
  • the bisector (reference angle holder) is directed at least approximately to the center of the loudspeaker (s) and / or the loudspeaker wall, which is attached to a predetermined sound distribution corner, this arrangement being composed of a Sc consisting of a plurality of sound-guiding surfaces (top and end surfaces) hall guide room, which has two sound openings, is surrounded.
  • the loudspeaker or the sound source can also be formed by loudspeaker systems with different frequency characteristics, and one or more loudspeaker systems of different types can be used, for example.
  • Membrane speakers, piezo speakers or the like With such a room-independent loudspeaker arrangement, which is set up, for example, in a corner of a room, a room can be completely sounded out without the impression of a sharply focused radiation.
  • the plastic quality of sound reproduction (hi-fi) is retained when acoustic reproduction of speech, signal tones, music or other noises within closed rooms of any size;
  • a loudspeaker arrangement can also supply partially open rooms of any size with sound or can be used anywhere in the great outdoors, whereby - provided the sound power is sufficient for a living space - optimal and plastic acoustic sound is possible outdoors, which is only limited by the laws of nature in the space to be created.
  • the sound spaces formed can be subdivided completely or partially, preferably symmetrically, from the speakers to the sound outlet, so that stereo control is possible when controlled by stereo signals.
  • two or more loudspeaker arrangements for mono or stereo reproduction are used at the boundary of a room or space, it is generally possible to create a completely - and / or from the environment in the broadest - independent acoustic space, which is a plastic surround sound reproduction of the respective original recording character, including that of unrestricted artificial head recording signals with true-to-original effect.
  • At least one cover surface is arranged which covers the space between the loudspeaker and the sound guide surface (s). In this way, a closed control room is formed, through which the sound from the loudspeaker is spatially deflected in two different directions and emitted at, for example, opposite shadow exit openings.
  • At least one cover surface on the loudspeaker can have an approximately rectangular corner, which can be referred to as the front corner.
  • This front corner can also cover the loudspeaker, the bisector of this corner being oriented at least approximately parallel to the reference bisector of the Sound guide surfaces.
  • the sound from the loudspeaker is thus in the form of the bow-like edge of the sound guide surfaces and / or the geometric bodies, which may also only be partially in front of it or inserted between this edge with or without a fixed connection, or approximately the center of a one-piece switch guide surface a Tei l morausiteses blasted a cylinder or a ball and divided there in approximately equal parts and deflected in approximately opposite directions.
  • the loudspeaker can expediently be attached to a loudspeaker wall which is only slightly larger than the sound opening of the loudspeaker, preferably the loudspeaker wall is smaller than twice the corresponding dimensions in height and width of the loudspeaker opening. If e.g. the speaker has an oval opening of 10 x 15 cm, the wall can have a size of 15 x 20 cm. In the case of loudspeakers lying next to one another, the dimensions in the width of the entire arrangements are correspondingly increased.
  • the surface of the loudspeaker opening or the loudspeaker wall is slanted at an angle of approximately 45 below the right-angled corner of the upper cover surface.
  • At least one additional sound guide surface can be attached to at least one sound guide surface.
  • Adjacent formwork guide surfaces are advantageously inclined at an obtuse angle from 100 ° to 170 °, preferably between 120 ° and 160 °.
  • the lower and the upper cover surface are formed approximately as superimposed squares, which are connected to one another at their edges by tussf so that the side of the speakers to the next square corner between the cover surfaces each an opening is formed, and that from the square corner mentioned to the sound guide surfaces, the cover surfaces, in particular at their edges, are connected by end surfaces.
  • partially closed sound guide rooms are formed in front of the loudspeaker in both directions of the sound flow, which are provided with sound outlet openings and from which the sound is radiated with the same intensity.
  • the space behind the loudspeaker or the loudspeaker wall can be connected to a space attached under the lower cover surface through an opening, openings on the rear corner opposite the loudspeaker corner opening through both cover surfaces attached from the bottom to the top and closed at the side. So the is from the back of the speaker radiated sound into the sub-room, which was designed as a resonance room, and from there to the top of the upper deck surface.
  • a possibly multi-part, further sound guide arrangement can then be attached, with which the upwardly directed sound is deflected forwards, backwards and / or laterally.
  • the further sound guide arrangement can have the shape of a sector of a round disk, the center of which coincides with the rear corner of the approximately square cover surface, which is opposite the rear corner, that of the front corner, in the vicinity of which the loudspeaker is arranged.
  • This disc has the shape of a quarter of a cytinder-shaped (round cake), but with an internal cavity. The sound emitted from the rear of the loudspeaker is fed to this cavity from below via the subspace and then deflected in the disk sector in the direction of its periphery, the peripheral surface being made of a sound-permeable material, e.g. a grid is formed.
  • At least one, approximately perpendicular to the top surface Schatlannons realization can be arranged within this further sound guide arrangement, which extends radially to the corner of the disk sector. In this way, an improved directivity can be achieved with the sound radiation become .
  • a special sound guide channel e.g. in the form of a tube with a round or square cross-section, lead to the lower or upper opening at the rear corner.
  • a certain selection of the intensity and / or frequency response of the sound from the subspace for radiation above the upper cover surface is possible.
  • the sound can be directed to two further, preferably flat, sound guide surfaces, which are attached behind the first switch guide surface and which radiate to the sides and / or to the rear, possibly via at least one sound deflection surface with which the sound , e.g. forward, is redirected.
  • the switch can be fed from the sub-room to the other sound guide surfaces.
  • the (first) sound guide surfaces can carry at least one opening through which a sound connection is made with the space behind the sound guide surfaces. Part of the sound is forwarded from the front of the loudspeaker to the rear, where it may be mixed with the sound from the subspace.
  • the loudspeaker or loudspeakers and possibly the loudspeaker wall could be assembled with at least part of the front corner, and this assembly could form a removable part of the loudspeaker arrangement. This part represents a kind of cassette that can easily be exchanged for another.
  • the sound guiding and closing surfaces with their dimensions located above the lower cover surface as well as the upper and lower cover surfaces can be made completely or partially foldable and / or removed and / or removed. It is thus possible to replace the loudspeaker (s) if a different frequency response or a different sound power or, if necessary, a different beam direction is required and, in addition, substantial transporter lighting can be achieved with large and musician loudspeaker systems of this type, since This universal hi-fi sound detour box training not only saves space by folding the upper half, but also, by removing or folding up the lower cover, below which this lower sound space is then available as storage space during transport.

  • Such an arrangement can in principle be open and, by dividing the sound cone from the loudspeaker 5 into the directions 6 and 7 and neighboring directions, will lead to a surround sound impression of the emitted sound.
  • the arrangement above and below the loudspeaker 5 and the sound guiding surface 1 is preferably through cover surfaces 8 and 9 covered, which can be formed by a square board. As a result, the space between the loudspeaker 5 and the sound guide surface 1 is closed. A further constriction and alignment of the sound outlet can be achieved in that the end surfaces 10 and 11, also shown in dashed lines, which can also be realized by boards, between the outer ends of the wings 2 and 3 and the associated corner 12 and 13th is closed. Thus, an opening is formed on the side of the loudspeaker 5 up to the front corner 14 behind the loudspeaker between the cover surfaces.

  • the loudspeaker is preferably mounted on a loudspeaker wall 15 which is slightly larger than the loudspeaker opening, in particular smaller than twice the corresponding dimension in height and width of the loudspeaker opening.
  • This speaker wall expediently closes the room at the front corner 14 behind the speaker 5. This entire space at the front corner 14 is expediently also closed off from the outside space by further shadow surfaces 16 and 17. Then only the sound emitted from the front of the loudspeaker 5 is fed to the sound guide surfaces 2 and 3.

  • Underneath is a subspace 19, which corresponds in cross-section to the square cover plate 9 and has a height that corresponds approximately to the height of the loudspeaker wall 5 and also to the height of the sound guide surfaces 1, 2, 3.
  • This sub-space is connected at the part adjacent to the front corner 14 via a dotted opening 20 to the space behind the loudspeaker 5.
  • This opening can also have any other shape, in particular comprise the entire triangle formed between the lower edge of the loudspeaker wall 5 and the corner 14; in this case, the lower cover surface 9 is completely eliminated in this area.
  • Sound passes through the opening 20 from the rear of the loudspeaker 5, which e.g. has a conical membrane into the subspace 19.
  • the sound emerging upward through the opening 26 can be deflected in any direction, in particular to the front, that is to say beyond the loudspeaker 5, by obliquely inclined sound guiding surfaces (not shown). But it can also be deflected to the sides, that is, according to arrows 6 and 7 in Fig. 2, whereby additional sound radiation is achieved in the front space.

Since the radius of this disk is equal to the edge length of the square of the upper cover surface 8, the edges of this sector, which also has an angle of 90 at its corner, lie parallel to the sides of the rear corner of the upper cover surface 8, and between The two lateral corners of this top surface 8 extend in the form of a cylinder section, a curved front surface of this disc.
  • the disc is closed with a board 30 as a further top surface and is otherwise hollow.
  • the cavity formed in this way is connected via the opening 26 to the subspace and through the opening 20 to the rear of the loudspeaker 5. Sound thus enters this cavity from the rear surface of the loudspeaker and is radiated forward through the front surface 29, since this front surface is made of sound-permeable material, e.g. a wire mesh or fabric covering.
