Description

[0001] The invention relates to a sound carrier base for producing a sound carrier by connecting the sound carrier base to a sound carrier attachment at a contact side of the sound carrier base facing the sound carrier attachment in a connected state, wherein the sound carrier base has a pivot point and a circumference arranged around the pivot point and is essentially round, wherein an interior space for receiving a filling for the sound carrier is arranged at the contact side. The invention further relates to a sound carrier with such a sound carrier base.

[0002] Known sound carriers, especially those composed of a base and a top section to form, for example, a cavity for holding a filling, are manufactured in such a way that the base and top sections are essentially identical and are simply spaced apart by means of a bead of adhesive to create the cavity. Achieving a defined distance between them is extremely difficult and depends particularly on the quantity and distribution of the applied adhesive. The resulting sound carrier can therefore, for example, exhibit an imbalance, which can disrupt the playback of music stored on it.

[0003] The purpose of the invention is to improve the state of the art.

[0004] The problem is solved by a sound carrier base for producing a sound carrier by connecting the sound carrier base to a sound carrier attachment at a contact side of the sound carrier base facing the sound carrier attachment in a connected state, wherein the sound carrier base has a pivot point and a circumference arranged around the pivot point and is essentially round, wherein an interior space for receiving a filling for the sound carrier is arranged on the contact side, wherein the contact side has a first spacer device with a first contact surface for contacting and connecting the sound carrier base to the sound carrier attachment.wherein, in the connected state, a first distance between the contact side of the record base and a meeting side of the record attachment is defined by means of a first height of the first contact surface above the contact side, and the interior space is geometrically defined between the record base and the record attachment by means of the first distance.

[0005] Using the first spacing device, a defined interior height can be created by means of the first spacing, so that the interior is geometrically defined by this first spacing. In particular, this significantly simplifies the joining process between the record base and the record attachment and results in fewer errors.

[0006] The following terms should be explained in this context:

[0007] A "sound carrier base" for the production of a sound carrier is one of two components of a sound carrier, consisting of the sound carrier base and a corresponding "sound carrier attachment." A sound carrier is, for example, a long-playing record (also called a vinyl record), a compact disc, a laser disc, or another, usually disc-shaped, technical device for storing audio or video information. The term "sound carrier" is used here as an example and also includes media carriers for, for example, feature films and / or other visual representations. The sound carrier, as well as the sound carrier base and the sound carrier attachment, is usually round or "essentially round," meaning it is geometrically designed in such a way that it can rotate around a pivot point.

[0008] It should be noted that the sound carrier is formed, in particular, by means of a conventional sound carrier, for example, a standard, well-known record with, for instance, a single-sided groove structure. The groove structure is, for example, a set of local information carriers for storing acoustic information, whereby the acoustic information is read by scanning the local information carriers with a scanning device, in the case of a record, a so-called needle, during rotation. Likewise, the local information carriers can also be read optically or magnetically, so that, for example, in the case of a compact disc, optically active local information carriers can be read using a laser. Together with the sound carrier base, a relatively simple sound carrier can thus be produced.To achieve an optical effect, the sound carrier attachment can be translucent or at least partially translucent.

[0009] The sound carrier is formed in a "connected state," meaning when the sound carrier base and the sound carrier attachment are joined together. In this connected state, a "contact side" of the sound carrier base faces the sound carrier attachment and serves, for example, for mechanical contact and fixation to a meeting side of the sound carrier attachment.

[0010] With respect to the pivot point, the sound carrier base has a "circumference," which describes geometric boundary points of the sound carrier base arranged radially from the pivot point and, in particular, orthogonally to a rotation axis passing through the pivot point. Specifically, the circumference of a round sound carrier, i.e., a round sound carrier base, is circular or cylindrical.

[0011] An "interior space" arranged at the contact side is a volumetrically free area of ​​the record base, which is free of material from the record base and can therefore accommodate a "filling". Such a filling is, for example, a material added within the finished record for an optical effect. For the present invention, the "interior space" is provided in a dimensionally stable manner within the record base and is geometrically defined.

[0012] A "spacer" is arranged on the contact side of the record base and serves to geometrically position a "contact surface," the latter of which mechanically contacts the record attachment associated with the record base. The spacer can, for example, be designed as a raised area, indentation, or protrusion on the contact side.

[0013] The spacer device has a "height," which defines the corresponding distance of the contact surface above the contact side. This height then defines the distance between the contact side of the record base and a "meeting side" of the record attachment. This meeting side is positioned correspondingly to the contact side of the record base and, together with the contact side of the record base, forms corresponding contact surfaces for connecting the record base to the record attachment.

[0014] By means of the spacer device, the interior space is "geometrically defined" by the first distance, meaning it is mechanically determined at least at one point, line, and / or surface, and thus, in particular, free from the influence of the joining process. It should be noted that the contact area can be macroscopically point-like, linear, and / or planar.

[0015] In order to define the geometric relationship of the record base to the record attachment more comprehensively and / or precisely, and, for example, to provide the interior with a defined profile independent of the joining method, the contact side has a second spacer device with a second contact surface, a third spacer device with a third contact surface, and / or a further spacer device with a further contact surface for contacting and connecting the record base to the record attachment, wherein, in the connected state, a second distance of the contact side is achieved by means of a second height of the second contact surface above the contact side, by means of a third height of the third contact surface, and / or by means of a further height of the further contact surface.a third distance of the contact side and / or a further distance of the contact side to the meeting side of the sound carrier attachment is or are geometrically defined and the interior space between the sound carrier base and the sound carrier attachment is formed with a defined profile together with the first distance and the second distance and / or the third distance and / or the further distance.

[0016] It should be noted that the "defined profile" refers to a height profile of the interior space defined by at least two, in particular three, four or more contact points or contact areas. For example, a corresponding arrangement of the respective contact surfaces and / or the respective spacers on the contact side of the sound carrier base can be used to create or increase stability, to achieve a particular appearance of the finished sound carrier, and / or to influence, for example, rotation around the pivot point.

[0017] In one embodiment, the first contact surface, the second contact surface, the third contact surface and / or the further contact surface is / are arranged concentrically to the pivot point, such that a partially annular first contact surface, second contact surface, third contact surface and / or further contact surface is formed and / or the first contact surface and the second contact surface, the third contact surface and / or the further contact surface is / are distributed in a matrix-like manner and / or arranged symmetrically to the pivot point.

[0018] "Concentric" in this context describes, for example, an arrangement in which the respective contact surfaces or components of the respective contact surfaces are arranged on a common radius around the pivot point. This creates a "partially ring-shaped" arrangement of the respective contact surface(s).

[0019] "Matrix-like" describes, in particular, a geometric arrangement that can be divided into lines, rows, and / or columns, whereby, in particular, a row direction and a column direction are arranged at right angles to each other and form a geometric matrix. "Symmetrical about the pivot point" describes, for example, a pattern of corresponding contact surfaces arranged symmetrically around the pivot point, which allows for an interesting optical image of the optical effect achieved, for example, by means of the filling. Furthermore, the rotation of the sound carrier can be improved or achieved by means of a matrix-like and / or symmetrical arrangement of the contact surfaces, provided that the center of gravity of the sound carrier is kept in the area of ​​the pivot point by means of the arrangement.

[0020] In order to enclose the interior and depict it as closed on the finished sound carrier, the first contact surface and / or the second contact surface is / are designed to be closed around the pivot point, so that the interior is closed in the connected state, wherein the first contact surface is in particular arranged circumferentially around the circumference.

[0021] "Closed" in this context refers specifically to a structure completely encased in material, such that, when connected, sufficiently small openings remain to securely hold the filling within the interior. If the filling is liquid, for example, no openings are present.

[0022] In one embodiment, the first height, the second height, the third height and / or the further height are arranged in a common contact plane and / or are essentially identical, so that the interior is uniform, in particular prismatic.

[0023] This shared “contact level” is a level at the base of the sound carrier, designed analogously to the encounter side, which comes into direct contact with the encounter side of the sound carrier attachment.

[0024] It should be noted that for both uniformly designed heights and for variable and / or differently designed heights, heights between a few tenths of a millimeter up to, for example, 3 mm, in particular 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, can be selected, wherein in particular the interior has a corresponding height of a few tenths of a millimeter up to, for example, 3 mm, in particular 0.5 mm, 1 mm, 1.5 mm, 2 mm and / or 2.5 mm.

[0025] To facilitate joining the record base to the record attachment, the first contact surface, the second contact surface, the third contact surface and / or the further contact surface have a structure for receiving an adhesive and / or for supporting welding.

[0026] For example, such a “structure” is a surface modification with, in particular, a defined roughness, which increases an adhesion surface or cohesion surface with an adhesive and / or which, for example, facilitates ultrasonic welding of the record carrier base to the record carrier attachment through a defined roughness.

[0027] In one embodiment, a material for manufacturing the sound carrier base comprises a plastic, in particular a vinyl and / or a polycarbonate, and / or the sound carrier base is translucent.

[0028] Plastic is used particularly for well-known sound carriers, allowing the base to be created and processed analogously to familiar materials. If the base is made "translucent," meaning it allows light to pass through and is especially transparent, then, for example, a completely transparent sound carrier can be created by combining the translucent base with a translucent top, allowing the corresponding filling to be visually displayed on both sides.

[0029] In order to produce a sound carrier that is playable on both sides, in particular, by means of the sound carrier base and the sound carrier attachment, the sound carrier base has local information carriers for storing acoustic information, in particular opposite the contact side, wherein it is possible to read out the acoustic information by means of scanning the local information carriers by means of a scanning device during a rotation of a sound carrier formed by means of the sound carrier base and in particular the sound carrier attachment.

[0030] In another aspect, the problem is solved by a sound carrier formed from a sound carrier base according to one of the previously described embodiments and a sound carrier attachment, wherein a filling is received in an interior space formed between the sound carrier base and the sound carrier attachment in a connected state, and the sound carrier base and / or the sound carrier attachment is or are translucent, such that the filling in the interior space creates an optical effect visible through the translucent sound carrier base and / or the translucent sound carrier attachment.

[0031] In one embodiment, the sound carrier attachment is formed by means of a second sound carrier base, wherein in particular the sound carrier attachment designed as a second sound carrier base is connected to the sound carrier base in a mirror-symmetric manner.

[0032] In particular, the filling is a liquid or a gel, or contains a liquid or a gel. Alternatively or additionally, the filling contains granules, mineral granules, in particular sand, and / or reflective particles, such that a changing optical effect is produced each time the sound carrier is rotated and / or moved.

[0033] In this context, a "liquid" is, for example, a flowable, deformable mass containing water, alcohol, or a polymer. A "gel," in this context, is a liquid-like mass with high viscosity, which may also be thixotropic or rheopexic.

[0034] A "granulate," on the other hand, is a mass of individual, deformation-resistant particles such as sand grains or plastic particles, which as a whole appear as a flowable mass and exhibit flowable behavior. Such a granulate may also contain reflective, fluorescent, glittering, or otherwise optically effective particles.

[0035] In another embodiment, the filling has a decorative layer, in particular with a pictorial representation, wherein the decorative layer particularly comprises paper, plant leaves and / or a fabric.

[0036] For example, to create a damping effect within the sound carrier and in particular to suppress scratching noises, disturbances and / or vibrations within the sound carrier, the filling consists of a foam, a porous material and / or an elastomer.

[0037] In a further embodiment, the sound carrier attachment has local information carriers for storing acoustic information, wherein it is possible to read out the acoustic information by scanning the local information carriers using a scanning device during a rotation of a sound carrier formed by means of the sound carrier base and in particular the sound carrier attachment.

[0038] The invention will now be explained in more detail using exemplary embodiments. These will show... Fig. 1. A schematic representation of a record base in an isometric view, Fig. 2 a schematic representation of another record base in an isometric view, Fig. 3 a schematic representation of a cutaway side view of a design record, as well as Fig. 4 A schematic representation of a cutaway side view of a reference record.

[0039] A record base 101 has a base body 103. The base body 103 is formed around a rotating axis 181, with a hole 121 in the rotating axis 181 serving to receive a record formed by the record base 101 on the spindle of a turntable. On its underside 191, the record base 101 has grooves 194 typical for records (in Fig. (1 not visible due to the chosen perspective). These grooves can be scanned when the underside 191 is turned towards the needle of a record player to play back grooves stored by means of the grooves 194.

[0040] On a contact side 193 opposite the underside 191, the base body 103 has a rim 105 arranged around a circumference 183, which projects beyond the base body 103 and forms a contact surface 131. Near the hole 121, an annular rim 107 is formed analogously to the rim 105, but with a significantly smaller radius around the axis of rotation 181, forming a contact surface 133. The contact surface 131 and the contact surface 133 have the same height above the base body 103, namely a height of 185. A receiving space 141 is thus formed between the annular rim 107 and the rim 105, in which color gel 151 can be received. This color gel 151 serves to create an optical effect in a record to be produced. It should also be mentioned that the record base 101 is made of translucent polyvinyl.

[0041] Another record base 201 is constructed analogously to the record base 101 and has a base body 203 with a rim 205, a ring rib 207 and contact surfaces 231 and 233 formed by means of the ring ribs (compare Fig. 2) at a height 285 above the base body 203. Furthermore, another ring web 211 is arranged directly around a hole 221 about a rotation axis 281. This ring web 211 forms a contact surface 237.

[0042] In contrast to the record base 101, the record base 201 has a plurality of button studs 209 in the area of ​​a recording space 241, each forming contact surfaces 235. The contact surfaces 231, 233, 235 and 237 are arranged in a common plane parallel to a bottom surface 291 of the record base 201. Thus, all contact surfaces are arranged in a common plane in the direction of a contact side 293.

[0043] Furthermore, the record base 201 has 291 grooves 294 on the underside, which, analogous to the example above, represent music in a readable way.

[0044] A design record 301 consists of the record base 201 and a record body 361 glued to it. The record body 361 rests on the edge rib 205 and the ring rib 207 at the respective adhesive seams 371, 373, and 375, and is glued to the base body 203 of the record base 201. The record body 361 also rests on the ring rib 211 and the respective button ribs 209. The colored gel 151 inside is contained in an interior space 341, which is geometrically defined by the respective ribs.

[0045] The resulting design record 301 is rotatable about a pivot axis 381 in a rotary mount 321 and, due to the geometrically defined design of the interior 341, is provided with a special concentricity. The grooves 294 and 395 on the record body 361 can be read by means of a needle, so that the design record can be played on both sides. A paper label, for example, can be affixed to a label area 376 located in the region of the pivot axis 381 to identify the design record 301.

[0046] A reference record 401 is formed by means of the record base 101 and a record body 461 glued to it, wherein an elastomer filling 451 is arranged in the resulting interior space 441. The elastomer filling 451 fills the interior space 441 completely and is positively locked in place at the adhesive seams 471 and 473 when the record body 461 is joined to the record base 101. When the reference record 401 is played on a turntable equipped with a stylus, the grooves 194 on the record base 101 and the grooves 495 on the record body 261 are excited to vibrate, thus reproducing music. The elastomer filling 451 serves to dampen unwanted vibrations in the reference record 401 itself, enabling particularly faithful music reproduction.

[0047] The disc body 361 and the disc body 461 are each translucent, so that the optical effect of the color gel 151 and the elastomer filling 451 is visible from both sides of the respective record.

[0048] It should also be mentioned that the interior space 441, as well as the interior space 341 or a comparable interior space, may also contain, for example, an image on a backing paper, a printed or woven fabric, natural materials such as leaves or leather, and other fillings.
