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.
- a loudspeaker arrangement is also already known in which the sound is conducted from at least one loudspeaker or another sound source via sound guide rooms to sound outlet openings.
- the loudspeaker is arranged opposite the two, preferably flat, sound guide surfaces, as seen in the direction of sound emission, which are bow-like inclined at an obtuse angle, the bisector (reference line) lying approximately in the middle of the height or width of the sound guide surfaces Bisector) is directed at least approximately to the center of the loudspeaker (US Pat. No. 2,858,899).
- housing walls are formed above the loudspeaker at an angle to the sound guiding surfaces, which cover the space between the loudspeaker and the sound guiding surfaces.
- the loudspeaker is arranged on a loudspeaker wall that is slightly larger than the loudspeaker opening and also acts as a sound guiding surface (FR-PS 2 579 852).
- the invention has for its object to provide a universal hifi-sound detour loudspeaker arrangement, which is housed in a more or less compact housing and with its special properties represents a universal hifi sound detour box, which is used to produce and / or reproduce surround sound of rooms as well as for particularly plastic and natural sound reproduction up to artificial head reproduction is suitable in all areas and thus represents a unique, unmistakable universal hi-fi sound detour box that is independent of the room.
- the loudspeaker (s), viewed in the direction of sound emission, are arranged opposite at least one sound guiding surface, which distributes and deflects approximately the impinging sound, of a partial section of a cylinder, a sphere or two, preferably flat, sound guiding surfaces which are bow-like under one obtuse angles are inclined towards each other and on or between which, with or without a fixed connection, geometrical bodies can be placed or inserted, with the bisector (reference bisector) at least approximately in the middle of the height or width of the sound guide surfaces is approximately directed towards the center of the loudspeaker (s) and / or the loudspeaker wall, which is attached to a predetermined sound distribution corner, this arrangement comprising a sound-guiding space consisting of a plurality of sound-guiding surfaces (top and end surfaces), which has two sound openings ha t, is surrounded.
- the loudspeaker or sound source can also be formed by loudspeaker systems with different frequency characteristics and one or more louds
- 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 maintained when acoustic reproduction of speech, signal tones, music or other noises within closed rooms of any size;
- Such 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 loudspeakers to the sound outlet, so that stereo control is possible when controlled by stereo signals. If 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 an acoustic space which is completely independent of the surroundings and which is the widest, and 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 enabled.
- a cover surface is arranged, which cover the space between the loudspeaker and the sound guide surface (s). In this way, a closed sound space is formed, through which the sound from the loudspeaker is spatially deflected in two different directions and radiated at, for example, opposite sound outlet openings.
- At least one top surface can be attached to the speaker, e.g. have an approximately rectangular corner above and / or below, 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 be only partially in front of it or inserted between this edge with or without a fixed connection, or approximately the center of a sound guide surface consisting of one piece a partial surface section of a cylinder or a ball is blasted and divided there into 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 inclined at an angle of approximately 45 ° under 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.
- a sound guide surface e.g. is hinged attached, the radiation direction of the sound can be influenced later.
- Adjacent sound guide surfaces are expediently inclined towards one another at an obtuse angle of 100 ° to 170 °, preferably between 120 ° and 160 °.
- the lower and the upper cover surface are, at least in part, approximately formed as superimposed squares, which are partially connected at their edges to one another by end surfaces in such a way that there is an opening on each side of the loudspeaker to the next square corner between the cover surfaces is formed, and that from the square corner mentioned to the sound guide surfaces, the top 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 communicate with a space attached under the lower cover surface through an opening, openings being made at the rear corner opposite the loudspeaker corner through both cover surfaces through the bottom upwards and are finished on the side.
- the sound emitted from the rear of the loudspeaker is converted into e.g. designed as a resonance room, sub-room and from there to the top of the upper deck surface.
- a further, possibly multi-part, further sound guide arrangement can then be attached to the upper cover surface, 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 cylindrical (round cake), but with an internal cavity. The sound emitted from the rear of the loudspeaker is supplied 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 sound dividing surface which is approximately perpendicular to the top surface, can be arranged within this further sound guidance arrangement, the radial runs to the corner of the disk sector. In this way, an improved directivity in sound radiation can be achieved.
- a special sound duct e.g. in the form of a tube with a round or square cross-section, to the lower or the 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 onto two further, preferably flat, sound guide surfaces, which are attached behind the first sound 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 sound from the subspace can be fed to the other sound guiding 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 passed on from the front of the loudspeaker to the rear, where it may be mixed with the sound supplied from the subspace.
- the loudspeaker or loudspeakers and optionally 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 is 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.
- a bug-shaped sound guide surface 1 is shown, which is formed from a first wing 2 and a second wing 3, which are assembled like a bug at an obtuse angle of about 150 °.
- the bow forms a vertical straight line 4.
- Fig. 1 shows the side view of the arrangement belonging to the plan view according to Fig. 2.
- a loudspeaker 5 is arranged opposite the bow, of which the center of its sound cone points approximately to the bow 4 and is oriented approximately parallel to the bisector of the two wings 2 and 3.
- the loudspeaker 5 is directed on both sides of the bow 4 onto the wings 2 and 3 and is radiated laterally, approximately in the direction indicated by the arrows 6 and 7, and distributed in the surrounding space.
- 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 in the environment.
- cover surfaces 8 and 9 which can each be formed by a square board.
- cover surfaces 8 and 9 can each be formed by a square board.
- 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.
- 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 sound guide surfaces 10 and 11 thus end at the legs of the angle of the rear corner.
- 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 closed to the outside space by further end surfaces 16 and 17. It will only be the one from the front of the loudspeaker 5 radiated sound is supplied to the sound guide surfaces 2 and 3.
- the division of the sound emitted by the loudspeaker 5 can be further improved by attaching a partition 18 to the bow 4 which points to the center of the loudspeaker 5 and at the same time is directed in the direction of the bisector of the angle formed by the wings 2 and 3.
- Fig. 3 shows an embodiment of the invention, which contains a loudspeaker arrangement approximately in its upper half, as is shown in FIGS. 2 is shown with the described additional parts.
- a subspace 19 which corresponds in cross section to the square cover plate 9 and has a height which 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.
- the overall arrangement with the subspace and the sound guiding space lying above it is closed off by rear walls which extend from lower edges 21 and 22 to upper edges 23 and 24 and together form a rear edge 25.
- the sound emitted from the rear of the loudspeaker 5 thus passes through the subspace 19 into the room behind the sound guide surfaces 1, 2, 3 upwards.
- the upper cover surface 8 carries in this area an opening indicated by the line 26, which can encompass the entire area between the sound guide surfaces and the rear walls 23 and 24.
- 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 guide 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.
- a further sound guide arrangement 27 which has the shape of a sector of a round disk, is attached to the upper cover surface 8.
- the rear edge 28, which corresponds to the axis in the center of the disk, is in alignment with the rear edge of the loudspeaker arrangement, also indicated by dashed lines, with the sound guide surfaces 1, 2, 3 and with the rear edge of the subspace 19. Since the radius of this Slice 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, are parallel to the sides of the rear corner of the upper cover surface 8, and between the two lateral corners of this cover surface 8 extends in the shape 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 communicates with the subspace via the opening 26 and with the rear of the loudspeaker 5 through the opening 20. 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.

- a small sound guide surface 36 is arranged in front of the corner 34, which essentially corresponds to the sound guide surface 1, 2, 3 and forms a bow-like edge in the direction of the loudspeaker 5.
- part of the sound radiated forward from the loudspeaker is thus transmitted into the space behind the sound guiding surfaces and is radiated there to the sides.
- a horizontal surface can be attached, preferably at approximately the level of the lower cover surface, running around the loudspeaker arrangement in whole or in part, as is indicated at 40.

- sound from the subspace can pass from the rear of the loudspeaker 5 through the openings 43, 44 of the small sound guide surface 42 into the space in front of the separating surface, since the space around the opening 61 is closed on the sides forming the corner 34.
- a straight wall 53 is inserted behind the sound guide surface 1, as in FIG. 5. However, this is provided with an opening 54. Opposite this opening, in front of the corner 34, there is again a small, angled sound guide surface 55 which forms a bow and is closed. Between the sound guiding surface 1 and the wall 53 there is an indicated opening 39, shaped as desired, through the lower cover surface to the subspace.
- FIG. 7 shows a further embodiment, in which a further, approximately equally shaped sound guide surface 58 is arranged behind the sound guide surface 1, the bow of which, however, points in the opposite direction, namely towards the rear corner 34.
- a straight wall 59 In front of this corner, at a distance of approximately 15% of the diagonal length, there is a straight wall 59 which carries an opening 60. Behind this wall 59 there is an opening 61 of any shape, shown in a circle in FIG. 7, which leads to the subspace 19 (cf. FIG. 3).
