Description

Technical Field

[0001] The present invention relates to a loudspeaker system having at least one loudspeaker unit and at least one assembly device, wherein the at least one loudspeaker unit is connectable to the at least one assembly device.

[0002] For mounting loudspeakers into furniture, motor vehicles, or fixed interior equipment, it is known to install recesses adapted to the loudspeaker system onto surfaces. Commonly found in motor vehicle construction are pre-machined recesses in door linings or other individual components of vehicle interior equipment. Some vehicle manufacturers provide loudspeaker systems with pre-machined standard openings for installation. However, these mounting openings vary between manufacturers. There is no international standard for loudspeaker system mounting openings.

[0003] In motor vehicles, speaker installation is often prepared using existing cable bundles. Within a motor vehicle cable bundle, there can be over one hundred different plug points and coupling points. Summary of the Invention

[0004] Therefore, the objective of this invention is to provide a loudspeaker system that has high variability and flexibility in installation.

[0005] The task upon which this invention is based is solved by a loudspeaker system having the features of Embodiment 1. Other advantageous designs are provided in dependent embodiments of Embodiment 1.

[0006] According to the present invention, a loudspeaker system is defined as being composed of different individual components. Here, the loudspeaker system has at least one loudspeaker unit and at least one mounting device, wherein the at least one loudspeaker unit is connectable to the at least one mounting device. For this purpose, it is possible that the mounting device is configured as a mounting frame for a plurality of loudspeakers. It is also possible that the mounting frame accommodates a plurality of loudspeakers (e.g., a midrange loudspeaker and a tweeter) arranged centrally and stacked together as a single loudspeaker unit. Here, according to the concept of the present invention, at least one mounting device is designed as a housing having at least two recesses facing inward, the recesses corresponding to protrusions on the outer side of at least one loudspeaker unit, in which case the housing accommodates at least one loudspeaker unit. In the housing, each of the at least two recesses has a tangential offset portion approximately centrally located, wherein a locking protrusion is present along the path of the tangential offset portion, the locking protrusion providing a clamping engagement (Klemmsitz) with the protrusion on the outer side of at least one loudspeaker unit. When the speaker is circular, the speaker unit, whether composed of a single speaker or including at least two speakers, has two tenons, i.e., mortise and tenon joints, on its outer periphery, or the speaker unit has protrusions in recesses into the outer casing. Within the recesses of the outer casing, offset portions exist in the plane of the outer casing. The tenons on the outer periphery of the speaker unit can be locked within the recesses by twisting about their own axis. In this respect, inserting at least one speaker unit into the outer casing is similar to a bayonet lock. However, it is not actually the same as a bayonet lock because there is no tension spring that secures the insertion portion in a groove of a bayonet lock.

[0007] In a first design of the loudspeaker system according to the invention, at least one loudspeaker unit and at least one mounting device are implemented in a circular shape in the area of ​​the housing. The circular embodiment allows the loudspeaker to be secured within the mounting device by twisting. Alternatively, it is equally possible to implement the housing and loudspeaker in a rectangular shape. For locking, the loudspeaker unit can then be pushed, rather than twisted, within the housing, to the extent permitted by the offset portion in the recess.

[0008] In the design of this invention, at least one mounting device can be connected to at least one speaker unit both forward and rearward. That is, the speaker unit can be recessed into the enclosure from the front, where "front" refers to the side of the speaker unit that the listener faces. Alternatively, it is equally possible to project the enclosure onto the periphery of the speaker unit from the rear, where "rear" refers to the side of the speaker unit that the listener faces away from when the speaker unit is used in compliance with regulations.

[0009] In this embodiment of the invention, the length of the tangential offset portion in the recessed groove is such that the protrusion on the outer side of at least one speaker unit can move past the locking protrusion when it is inserted into the outer casing. Thereby, the clamping fit is removed again, and the tenon or protrusion on the speaker unit is secured in the offset portion.

[0010] This structure of the entire speaker system allows for the combination of speakers, which incur higher production costs than assemblies, with different assembly components. This enables the creation of, for example, an assembly unit for each vehicle product, combined with standardized speaker units. However, the quality of the speaker units also varies. One could install a very high-quality speaker unit with extremely high sound purity, or similarly, a speaker unit with less high-quality sound and consequently, a lower cost.

[0011] However, the speaker system to be installed must not only meet different mounting frames and mounting locations, but also different electrical installation conditions. Because there are often more than 100 different types of plug connectors with intentionally different shapes in the cable compartment of a vehicle, it is common for each speaker to have a very personalized electrical plug contact type across different vehicle models or brands. Therefore, the shape of the plug contact needs to be changed to achieve clarity in cable distribution. Due to the complexity of the cable compartment, it is almost impossible to trace the path of each cable in a reasonable amount of time. Instead, the following approach is adopted: each plug head matches its corresponding plug contact like a key. To accommodate such a large variety of variations, the design of this invention specifies that at least one receiving socket exists on at least one speaker unit, and at least one support pin in the form of a wire nail serves as an electrical contact, wherein at least one receiving socket corresponds to a socket insertion portion, the socket insertion portion having an opening in the area of ​​the support pin. The socket insertion portion functions like a lock cylinder in an existing lock. Here, the opening in the socket insertion section has a shape corresponding to the electrical contact section in the existing cable compartment. By separating the socket insertion section from the receiving socket, the socket insertion section can be conveniently manufactured with a wide variety of shapes and connected to the speaker unit. This allows for the selection of a personalized socket insertion section for each vehicle model with a predetermined plug type.

[0012] To connect the socket insertion portion to the receiving socket as quickly and cost-effectively as possible, the design of this invention specifies that the socket insertion portion has at least one positioning protrusion, each of which corresponds to a positioning opening in at least one receiving socket. For fixation, the socket insertion portion is pushed into the receiving socket, wherein the plastic-made socket insertion portion undergoes very slight elastic deformation until the positioning protrusion is embedded in the positioning opening and the receiving socket undergoes elastic restorative deformation.

[0013] Depending on the type of plug, it may be necessary to orient the socket insertion portion in a specific direction toward the speaker unit. This is particularly relevant for plug plates that match the shape of the speaker or for fixed multi-prong plugs. To unify the orientation of the socket insertion portion, according to another design according to the invention, a guide protrusion or guide groove is provided on the inner side of at least one receiving socket, corresponding to the guide groove or guide protrusion on the outer side of the socket insertion portion.

[0014] To provide a decorative or protective covering layer for the sensitive speaker diaphragm, in another embodiment of the invention, a mesh can be positioned between the speaker unit and the enclosure, the mesh extending over the surface of the speaker diaphragm of at least one speaker unit. The mesh can be composed of individual spokes, with fabric stretched taut over it. However, it is equally possible to use a plain or patterned perforated metal plate with holes in two dimensions.

[0015] The speaker system described herein can be sold separately. The speaker system comprises a speaker unit, a mounting device as an outer casing, a socket insertion part, and, in some cases, a covering grille. However, it is also possible to sell higher-value speaker systems as a package, wherein the package comprises a speaker unit, at least two mounting devices, and / or at least two socket insertion parts integrated for installation in different motor vehicles.

[0061] Figure 1An exploded perspective view of the loudspeaker system 100 according to the invention is shown from the rear, i.e., from the side opposite the listener. The loudspeaker system 100 has at least one loudspeaker unit 110. It is also possible that at least two loudspeakers are concentrically and overlappingly arranged in the loudspeaker unit 110, or that at least two loudspeakers are housed in a common mounting device 120. Furthermore, the loudspeaker system 100 has the at least one mounting device 120. The at least one loudspeaker unit 110 is connectable to the at least one mounting device 120. According to the design of the loudspeaker system 100 described herein, the mounting device 120 is designed as a housing. The housing has three recesses 122 on its inward side 121 corresponding to protrusions 112 on the outer side 111 of the loudspeaker unit 110 shown herein, particularly when the housing houses the at least one loudspeaker unit 110. The two recesses 122 each have a tangential offset portion 123 approximately centered, wherein a locking protrusion 124 is present along the path of the tangential offset portion 123. This locking protrusion, when a conventional connection is present in this embodiment, provides a clamping engagement with the protrusion 112 provided on the outer side 111 of the at least one speaker unit 110. The locking protrusion 124 is further illustrated in the following figures.

[0062] A variation of the loudspeaker system 100 shown here further includes a receiving socket 130 on the loudspeaker unit 110. In this receiving socket 130, at least one support pin 131 in the form of a wire pin serves as an electrical contact within an opening. Depending on the type of loudspeaker, there may be only one grounded contact, i.e., the metal frame of the loudspeaker. However, it is also possible to have ungrounded contacts, and two electrodes serving as contact pins for each individual loudspeaker of the loudspeaker unit 110. The receiving socket 130 corresponds to a socket insertion portion 140, which itself has an opening 141 in the area of ​​the support pin 131. A corresponding plug contact 160 of the cable compartment can be fitted into the opening 141, wherein only the plug contact, not the wire of the cable compartment, is shown here.

[0063] Figure 2 The same speaker system 100 is shown in a stereoscopic perspective view from the front, i.e., facing the listener, in order to illustrate... Figure 1 All features in. For Figure 1 The accompanying drawings also describe... Figure 2 It is of reference value.

[0064] Figure 3.1The image shows an assembly device 120 serving as a housing in a loudspeaker system 100 according to the invention, with prominent details A and B. The view shown here centers on a recess 122, with details A and B positioned on the inner side 121 of the assembly device 120. The recess 122 is open towards its top side. When connected to the loudspeaker unit 110, a protrusion 112 of the loudspeaker unit 110 is inserted into the top opening of the recess 122. A tangential offset portion 123 of the recess 122 is present at the bottom of the first step of the recess 122. If the protrusion 112 touches the bottom of the first step, the loudspeaker unit 110 rotates within the assembly device 120 toward the tangential offset portion located in the plane of the housing. Figure 3.2 Detail A highlights the path of the protrusion 112 on the speaker unit 110. Arrow P indicates the path of the protrusion 112 on the speaker unit 110 in the recess 122, which begins with a vertical downward movement, then turns tangentially, and then moves downward vertically again when the offset portion 123 is sufficiently wide. It is also possible that the offset portion 123 is so short that a second vertical downward movement does not occur. The embodiment shown here is configured such that the recess 122 is located inside the outer casing, and the protrusion 112 is located on the outer periphery of the speaker unit 110. However, according to the concept of the invention, it is also possible that the configuration is designed in reverse. Thus, the protrusion 112 is located on the inner side of the outer casing, and the recess 122 is located on the outer side 111 of the at least one speaker unit 110.

[0065] Figure 3.3 Details according to the invention are now shown in detail B. The recess 122 has a locking protrusion 124. Depending on the length of the offset portion 123, it is possible that the locking protrusion 124 causes a clamping engagement of the protrusion 112 on the speaker unit 110, thereby securing the speaker unit. However, if the offset portion 123 is longer, it is equally possible that the protrusion 112 on the speaker unit 110 is pushed over the locking protrusion 124 and fixed in the offset portion 123.

[0066] Figure 4.1The top first row shows three views of the socket insertion portion 140 of the speaker system 100 according to the invention; the bottom second row shows three views of the openings of different socket insertion portions 140 for different plug contacts 160. The socket insertion portion 140 functions similarly to a lock cylinder in a lock. For this purpose, the socket insertion portion 140 itself has openings 141 of different shapes, which, together with the shape of a plug contact 160 specifically designed for a particular vehicle model, form a form-lock and correspond to that plug contact 160. To secure the socket insertion portion 140 in a receiving socket 130 on the speaker unit 110, one or more positioning protrusions 142 may be present on the outer side of the socket insertion portion 140, each positioning protrusion embedding into a corresponding positioning opening 132 of the receiving socket 130. The opening 141 specifically for the plug contact provides space for a support stud 131 in the receiving socket 130, the support stud existing in the form of a pin on the bottom of the receiving socket 130.

[0067] Figure 4.2 The speaker unit is shown to illustrate the basis of... Figure 4.1 The diagram illustrates how the socket insertion portion 140 is integrated with the speaker unit 110. A broad arrow indicates how the socket insertion portion 140 is inserted into the receiving socket 130. In this diagram, the socket insertion portion 140 has a guide groove 145 on its outer side, which engages with a guide protrusion 135 on the inner side of the receiving socket 130, such that the socket insertion portion 140 can only be inserted into the receiving socket 130 in one manner.

[0068] Figure 5 Finally, another detail is shown to illustrate how the protective or decorative grille 150 for the speaker diaphragm 129 of the speaker unit 110 is inserted into the mounting device 120. Here, the protective or decorative grille 150 is inserted into the mounting device designed as a cover, and the speaker unit 110 is then inserted into the cover, so that the protective or decorative grille 150 is clamped between the cover and the speaker unit 110.
