Description

[0001] The invention relates to a loudspeaker device for a vehicle according to the preamble of the independent patent claim. Furthermore, a motor vehicle with a loudspeaker coupling device and such a loudspeaker device is provided.

[0002] Today's vehicles feature a multitude of loudspeaker systems arranged in different positions. However, their arrangement and design vary from vehicle to vehicle, requiring a custom-designed loudspeaker system. The visual appearance of the loudspeaker system is always tailored to the specific vehicle. Particularly with a common-parts strategy, it may be the case that a loudspeaker system cannot be perfectly integrated into the vehicle design, nor can the loudspeaker system be customized. Furthermore, loudspeaker systems in a vehicle are inflexible and can only be controlled centrally.

[0003] DE 10 2017 201 961 A1 discloses a generic mobile loudspeaker unit for a motor vehicle. This comprises a first loudspeaker for acoustically reproducing audio data and a coupling interface for mechanically and / or electrically coupling the mobile loudspeaker unit to a complementary vehicle interface of the motor vehicle.

[0004] DE 10 2013 224 131 A1 discloses a device for providing sound to the interior of a vehicle. The device comprises a sensor device configured to detect a user's gesture and provide a signal characterizing the gesture.

[0005] From DE 198 51 490 A1 a nozzle arrangement for the ventilation or sound system of a vehicle interior is known.

[0006] From US 2015 / 0 224 942 A1, an audio device is known which is designed to be installed in a vehicle. The device comprises at least one internal speaker, a processor which is designed to receive and process a signal from at least one audio source and to transmit and play the processed signal through the at least one internal speaker, and an amplifier which is designed to amplify the processed signal transmitted by the processor, wherein the at least one internal speaker, the processor and the amplifier are all contained in a single unit, and wherein the device is configured to fit substantially into a mounting location of a vehicle head unit.

[0007] The object of the present invention is to provide a loudspeaker device that is easily adaptable to different situations and mounting locations in a vehicle.

[0008] The object is achieved by the subject matter of the independent patent claims. Advantageous developments of the invention are disclosed by the dependent patent claims, the following description, and the figures.

[0009] The invention provides a loudspeaker device for a vehicle. The loudspeaker device comprises at least a first loudspeaker for acoustically reproducing audio data, which is arranged on a first side of the loudspeaker device, a vehicle coupling device configured for mechanically and electrically coupling the loudspeaker device, and an operating element configured for controlling the loudspeaker device.Furthermore, at least one second loudspeaker is provided for the loudspeaker device for acoustic reproduction of the audio data, which second loudspeaker is arranged on a second side of the loudspeaker device, wherein a spatial orientation of the first and second sides differ from one another and wherein control element coupling devices are provided for the loudspeaker device, which are each arranged on the first and second side of the loudspeaker device, wherein the control element coupling devices are designed to couple the control element to the loudspeaker device.

[0010] In other words, a loudspeaker device for a vehicle is provided, which has at least two loudspeakers on different sides of the loudspeaker device and a vehicle coupling device, which is preferably designed to mechanically and electrically couple the loudspeaker device to the vehicle. Furthermore, the loudspeaker device has an operating element that can be coupled to the loudspeaker device on one of the sides on which the loudspeakers are located by means of operating element coupling devices.

[0011] The loudspeaker device can be designed as a three-dimensional geometric body, for example, a cube, cuboid, prism, pyramid, or even rotationally symmetrically as a sphere or cylinder. The first loudspeaker can be mounted on one side of the geometric body and the second loudspeaker on another side of the geometric body, so that they are spatially offset from each other in such a way that the radiating surfaces of the loudspeakers do not point in the same direction.

[0012] The vehicle coupling device can, for example, be configured to supply the loudspeaker device with electrical power and audio data, in particular with power and audio data from the vehicle. Furthermore, the vehicle coupling device can establish a reversible and non-destructive mechanical connection to the vehicle, for example via a plug connection, screws, and / or a rail with a slide lock.

[0013] Preferably, the vehicle coupling device can couple the loudspeaker device to the vehicle in such a way that either the first side with the first loudspeaker points into a vehicle interior or the second side with the second loudspeaker. This means that the loudspeaker device can be coupled to the vehicle by means of the vehicle coupling device, for example, in a first setting in which the first loudspeaker is at the front and in a second setting in which the second loudspeaker is at the front. To change the settings, the loudspeaker device can, for example, first be uncoupled, then the loudspeaker device can be brought into the desired setting, for example by spatially rotating it, and then the loudspeaker device can be coupled again with the second setting.For this purpose, the vehicle coupling device can be designed such that, depending on the spatial orientation of the loudspeaker device, mechanical and electrical coupling is possible. For example, coupling elements of the vehicle coupling device can be provided on one or more sides of the loudspeaker device.

[0014] The control element for controlling the loudspeaker device can, for example, control functions of the loudspeaker device, in particular simple functions such as volume, play, pause, and skip. For this purpose, the control element can have buttons that, when pressed, execute one of the aforementioned functions. Preferably, the control element can only control the loudspeaker device assigned to the control element. Alternatively, several loudspeaker devices can also be provided in the vehicle, with the control element being able to control each of the loudspeaker devices. Particularly preferably, individual functions of the control element can also be controllable only for the assigned loudspeaker device, while other functions can be controllable for all.

[0015] The control element coupling device, which is arranged on the first and second sides of the loudspeaker device, can be a slot for the control element. The control element coupling devices can comprise an electrical contact for supplying the control element with power and simultaneously mechanically holding the control element in or on the loudspeaker device. After being coupled to the loudspeaker device, the control element can establish a connection to the loudspeaker device by means of one of the control element coupling devices in order to control the loudspeaker device. The connection can be established, for example, via electrical contacts or wirelessly.

[0016] Preferably, both the first loudspeaker and the second loudspeaker are active during operation of the loudspeaker device. Alternatively, only the loudspeaker on whose side the control element is coupled by means of the control element coupling device can be active.

[0017] The invention provides the advantage that a non-directional design can be provided for the loudspeaker device, thus providing a high degree of differentiation potential even when the loudspeaker device is designed to be identical in terms of parts. Using the control element coupling devices, the control element can also be flexibly adapted depending on the orientation of the loudspeaker device. Furthermore, the control element can provide quick and easy access to the loudspeaker device for a user. Thus, a loudspeaker device can be provided which, thanks to its non-directional shape, can be mirrored or rotated for right- or left-hand installation in the vehicle, whereby the control element can be adapted in each case.Thus, a loudspeaker device can be provided which is cost-effective due to a common parts strategy and which can be easily adapted to different situations and mounting locations in a vehicle.

[0018] The invention includes embodiments which provide additional advantages.

[0019] One embodiment provides that the second side is arranged on the side of the loudspeaker device opposite the first side.

[0020] In other words, the first side is diametrically opposite the second side. This means that, for example, a body of the loudspeaker device has the first loudspeaker on one side and the second loudspeaker on the other side of the body. In particular, the loudspeaker device can be constructed symmetrically. This embodiment offers the advantage that the loudspeaker device can be flexibly installed in the vehicle by rotating it 180 degrees. For example, the appearance of the first side and the second side can be different. By rotating it, a desired appearance of the loudspeaker device can be achieved. Alternatively, the loudspeaker can be installed with the first side on a left side of the vehicle and with the second side on a right side of the vehicle.Thus, the loudspeaker device can be arranged flexibly in the vehicle, whereby a common parts strategy can be maintained during production of the loudspeaker device, which reduces costs in the production of the loudspeaker device.

[0021] A further embodiment provides that the first side and the second side of the loudspeaker device have a cover coupling device which is designed to couple a loudspeaker cover to the respective side of the loudspeaker device. In other words, both sides have a cover coupling device which can connect a loudspeaker cover to the loudspeaker device reversibly and non-destructively. For example, the cover coupling device can have a plug connection into which the loudspeaker cover can be latched. The loudspeaker cover can visually or mechanically shield the first and / or second loudspeaker, so that they are protected from external influences. The loudspeaker cover can be made of fabric, plastic or metal, for example, and can have a perforated grid structure, rib structure and / or fabric structure.This embodiment has the advantage that the loudspeaker cover for the loudspeaker device can be flexibly selected and that mechanical protection of the loudspeakers can be created.

[0022] Preferably, the loudspeaker cover has a perforated structure on at least one side of the loudspeaker device, which is designed to predetermine a directional characteristic of the emission of sound waves for the acoustic reproduction. In other words, a structure of the loudspeaker cover is designed such that sound waves are emitted in a directed manner. A perforated structure means, for example, a grid structure with multiple holes that point in the spatial direction in which the sound waves are to be emitted in order to generate the directional characteristic. The directional characteristic can be, for example, that sound waves that would emerge from the loudspeaker in the form of spherical waves are dampened in certain spatial directions by means of the perforated structure and are allowed to pass through in other spatial directions.Thus, the intensity of the sound waves is increased in predetermined spatial directions due to the pinhole structure, thereby creating the directional characteristic. This design offers the advantage that the speaker cover, in addition to an optical and mechanical effect, also influences the sound of the speaker device.

[0023] One embodiment provides that the operating element has an operating surface with a plurality of operating units, and wherein the operating surface is positively connected to the loudspeaker device when the operating element is coupled to the operating element coupling device, such that the operating surface is arranged on a surface of the first side or the second side of the loudspeaker device. In other words, the operating element can be inserted into the operating element coupling device of the loudspeaker device in such a way that only one operating surface with the plurality of operating units is visible on the surface of the loudspeaker device. For this purpose, the operating element coupling device can have a shaft within the loudspeaker device, and the operating element can be fitted into this shaft, such that only the operating surface is visible during coupling.The control units can, for example, be buttons that can be used to control functions of the loudspeaker device. This design offers the advantage that the control element can be adjusted to the respective side depending on the orientation of the loudspeaker device. The form-fitting design ensures that no dirt can enter the loudspeaker device.

[0024] Preferably, the control surface has a touch-sensitive screen, wherein the touch-sensitive screen is configured to display the control units and, upon touching one of the control units, to perform an associated function for controlling the loudspeaker device. In other words, the control surface of the control element is a touch-sensitive screen that can display the control units as symbols. Thus, the control units can be flexibly adapted to the loudspeaker device, since they are changeable.

[0025] One embodiment provides that the loudspeaker device has a data transmission device, wherein the data transmission device is designed to provide a data connection for receiving the audio data. In other words, the audio data can be sent wirelessly to the data transmission device of the loudspeaker device. The data transmission device can be, for example, a WLAN module, a radio module according to a radio standard such as 4G or 5G and / or Bluetooth. In particular, the data transmission device can establish the data connection with the vehicle and / or with a user's mobile device in order to receive audio data. This embodiment offers the advantage of simplifying the cabling of the loudspeaker device.In addition, the loudspeaker device can be designed more flexibly, since audio data can also be received from a mobile device, such as a smartphone, and the loudspeaker device can thus be controlled directly without having to provide the audio data via the vehicle.

[0026] A further embodiment provides that the loudspeaker device has a plurality of loudspeakers arranged on several sides of the loudspeaker device, wherein a control element coupling device is provided for each side. In other words, in addition to the first and the second loudspeaker, further loudspeakers can also be provided which are attached to different sides of the loudspeaker device. For example, the loudspeaker device can have a cuboid-shaped body and the loudspeakers can be arranged on two, four or six sides of the cuboid. For example, the loudspeaker device can also have a cylindrical body, wherein the cylindrical body can have a hexagon, octagon or polygon as its base, for example.Thus, a loudspeaker can be provided for each side, and the loudspeaker device can be rotated as desired so that it can be installed in the vehicle with a suitable shape. Preferably, the loudspeaker device can be constructed rotationally symmetrically. This embodiment allows for an even more flexible design of the loudspeaker device.

[0027] According to the invention, a motor vehicle is also provided with a loudspeaker coupling device and the loudspeaker device according to one of the preceding embodiments. The loudspeaker coupling device is designed to couple to the vehicle coupling device such that the first side or the second side of the loudspeaker device is arranged towards a vehicle interior. In other words, the motor vehicle can have a loudspeaker coupling device that can couple to the loudspeaker device such that either the first side faces into a vehicle interior or the second side faces into the vehicle interior. The loudspeaker coupling device of the vehicle can, for example, establish a mechanical connection and also have electrical contacts that provide an electrical connection to the loudspeaker device.This means that the vehicle's loudspeaker coupling device and the vehicle coupling device of the loudspeaker device can be designed to complement each other, allowing them to be connected reversibly and non-destructively. This embodiment of the invention allows for a more flexible arrangement of the loudspeaker device in the motor vehicle, resulting in the same advantages and variation possibilities as with the loudspeaker device.

[0028] In one embodiment of the motor vehicle, it is provided that the loudspeaker coupling device is arranged on an interior element of the motor vehicle, wherein the loudspeaker coupling device is further designed to arrange the loudspeaker device at a predetermined distance from the interior element during coupling. In other words, the loudspeaker device does not lie directly against an interior element of the motor vehicle, but is preferably at a distance from it. Preferably, the loudspeaker coupling device can also be movable, i.e. pivotably mounted, so that one side of the loudspeaker device can be aligned with the interior of the motor vehicle. An interior element on which the loudspeaker coupling device is provided can be, for example, a seat or a door or a door panel of the motor vehicle.This embodiment provides the advantage that the interior element can serve as a resonance body, thus improving the output of the audio data. In particular, one side of the loudspeaker device can face into the interior of the motor vehicle, and the other side can face toward the interior element, with sound waves from the second side being reflected by the interior element and thus also being able to be radiated into the vehicle interior. This allows for a more flexible arrangement of the loudspeaker device while maintaining audio output quality.

[0029] The invention also includes further developments of the motor vehicle according to the invention that have features already described in connection with the further developments of the loudspeaker device according to the invention. For this reason, the corresponding further developments of the motor vehicle according to the invention are not described again here.

[0030] The motor vehicle according to the invention is preferably designed as a motor vehicle, in particular as a passenger car or truck, or as a passenger bus or motorcycle.

[0031] The invention also includes combinations of the features of the described embodiments.

[0032] Exemplary embodiments of the invention are described below. Shown are: Fig. 1 is a schematic diagram of a loudspeaker device according to an exemplary embodiment; Fig. 2 shows an illustration of a control element and a first and second side of the loudspeaker device according to an exemplary embodiment; Fig. 3 is a schematic representation of a motor vehicle with a loudspeaker coupling device and a loudspeaker apparatus according to an exemplary embodiment; Fig. 4 a schematic representation of a motor vehicle with a loudspeaker coupling device and a loudspeaker device according to another exemplary embodiment.

[0033] The exemplary embodiments explained below are preferred embodiments of the invention. In the exemplary embodiments, the described components of the embodiments each represent individual features of the invention that can be considered independently of one another, each of which also develops the invention independently of one another. Therefore, the disclosure is intended to encompass combinations of the features of the embodiments other than those shown. Furthermore, the described embodiments can also be supplemented by further features of the invention already described.

[0034] In the figures, the same reference symbols denote elements with the same function.

[0035] In Fig. 1 shows a schematic side view of a loudspeaker device 10 according to an exemplary embodiment. In this exemplary embodiment, the loudspeaker device 10 can be cuboid-shaped and have at least a first loudspeaker 12 on a first side 14 of the loudspeaker device 10 and a second loudspeaker 16 on a second side 18 of the loudspeaker device 10. The loudspeakers 12 and 16 can be designed to acoustically reproduce audio data. In addition to the loudspeakers 12 and 16 shown here, further loudspeakers can also be provided on the respective sides 14, 18, which can be, for example, tweeters, midrange speakers, woofers, or bass loudspeakers.

[0036] Preferably, the first loudspeaker 12 and the second loudspeaker 16 can be arranged on opposite sides of the loudspeaker device 10 so that they face each other and can radiate sound in different directions. However, in another embodiment, the loudspeakers 12 and 16 can also be offset by 90 degrees from each other.

[0037] Furthermore, the loudspeaker device 10 can have an operating element 20, which can be designed to control the loudspeaker device 10. The operating element 20 can for this purpose have an operating surface 22, which can, for example, comprise a plurality of operating units (not shown in this figure). The operating units can, for example, be buttons with which simple functions of the loudspeaker device 10 can be controlled, such as volume. However, the operating surface 22 can preferably also be a touch-sensitive screen, i.e., a touchscreen, on which the operating units can be displayed. A respective function can then be executed by touching the location of the displayed operating units.

[0038] The operating element can preferably be an element that can be detached from the loudspeaker device 10. This means that the operating element can be removed from the loudspeaker device 10 or added to it. For this purpose, the loudspeaker device 10 can have an operating element coupling device 24, which can be provided in particular on the first side 14 and the second side 18. The operating element coupling device 24 can, for example, be designed as a shaft within the loudspeaker device 10, into which the operating element 20 can be inserted in a form-fitting manner, so that only the operating surface 22 is accessible to a user. Furthermore, the operating element coupling device 24 can have electrical contacts that can provide an electrical power supply to the operating element 20. For example, control commands can also be sent from the operating element 20 to the loudspeaker device 10 via these contacts.Alternatively or additionally, a control command of the control element 20 can also be sent to the loudspeaker device 10 via a wireless radio connection.

[0039] For this purpose, for example, a data transmission device 26 can be provided that can establish a wireless data connection. In addition to a data connection to the control element 20, the data transmission device 26 can also establish a wireless data connection to a transmitter via which the audio data to be reproduced by the loudspeaker device 10 can be obtained. For example, audio data can be obtained from a motor vehicle and / or a mobile terminal.

[0040] Preferably, the loudspeaker device 10 can have a cover coupling device 28, by means of which a loudspeaker cover 30 can be attached to the loudspeaker device 10. For example, the cover coupling device 28 can have plug connections on the first side 14, into which the loudspeaker cover 30 can be plugged using suitable plugs, and the second side 18 can have corresponding plug connections as a cover coupling device 28, with which the loudspeaker cover 30 can be attached. In this exemplary embodiment, the loudspeaker cover 30 is attached only to the second side 18. However, the loudspeaker cover 30 can alternatively or additionally also be attached to the first side 14.

[0041] In particular, the loudspeaker cover 30 can have a metallic perforated grid structure that protects the loudspeakers 12, 16 from mechanical impact. Particularly preferably, the loudspeaker cover 30 can predetermine a design so that the loudspeaker device 10 can be flexibly customized depending on the vehicle or user requirements. The loudspeaker cover 30 can also have a perforated structure, by means of which a directional characteristic of sound waves can be generated. This means that by means of the perforated structure (not shown in this figure), the sound waves can be focused, for example, in one spatial direction, thus creating the directional characteristic. For example, sound waves can thus be deflected primarily downwards, upwards, forwards, or sideways.

[0042] In addition, the loudspeaker device 10 can have a vehicle coupling device 32, by means of which the loudspeaker device 10 can be mechanically and electrically coupled to a vehicle. In this exemplary embodiment, the vehicle coupling device 32 can comprise slide-in rails on the first and second sides 14, 18, respectively on a top and bottom side of the loudspeaker device 10, by means of which slide-in rails the loudspeaker device 10 can be reversibly and non-destructively connected to the vehicle, in particular to a loudspeaker coupling device of the vehicle (not shown in this figure). In particular, by means of the vehicle coupling device 32, the loudspeaker device 10 can be connected to the vehicle in such a way that either the first side 14 or the second side 18 faces into a vehicle interior. The loudspeaker device 10 can thus be easily replaced.Depending on which side of the vehicle the loudspeaker device 10 is to be arranged, the corresponding side can be connected to the vehicle by means of the vehicle coupling device 32. Preferably, in addition to the mechanical connection, the vehicle coupling device 32 can also have electrical contacts that supply the loudspeaker device 10 with power.

[0043] This allows identical parts to be used for the loudspeaker device 10 on each side of the vehicle, since the loudspeaker device 10 can be flexibly mounted on either side using the vehicle coupling device 32. This means that a common parts strategy can be pursued, which can save costs.

[0044] Depending on the side of the loudspeaker device 10 mounted in the vehicle, the control element 20 can also be decoupled from the control element coupling device 24 and recoupled to the control element coupling device 24 on the desired side. In addition, the appearance of the loudspeaker device 10 can be changed quickly and flexibly using the cover coupling device 28.

[0045] In Fig. Figure 2 shows another exemplary embodiment of the loudspeaker device 10. In this figure, the first side 14, the second side 16, and the control element 20 are shown separately. This means that, for example, the first side 14 can be arranged on the back of the second side 18, or vice versa. Furthermore, in this figure, the control element 20 is shown in a connected state with the respective side 14, 18 of the loudspeaker device 10 and once in a non-coupled state.

[0046] In this embodiment, the control element 20 can be designed, for example, as a plug-in card having the control surface 22 with control units 23 on one narrow side. On a rear side, the control element 20 can, for example, have electrical contacts with which a power connection can be established.

[0047] In this exemplary embodiment, the first side 14 can have the speaker cover 30, which can, for example, have the appearance shown. In contrast, the second side 18 can have a different speaker cover 31, which can create a different appearance. Thus, depending on the desired appearance of the speaker cover 30, 31, the speaker device 10 can be flexibly attached either with the first side 14 facing forward or with the second side 18. The control element 20 can then be inserted into the side located at the front. In this way, the appearance of the speaker device 10 can be changed quickly and flexibly.

[0048] In Fig. 3 schematically shows a motor vehicle 34 having a loudspeaker device 10. In this exemplary embodiment, the loudspeaker device 10 can be connected to the motor vehicle 34, in particular to an interior element 38, which can be a vehicle door, for example, via the vehicle coupling device (not shown in this figure) with a loudspeaker coupling device 36. In this exemplary embodiment, the loudspeaker coupling device 36 can be rod-shaped. Preferably, the loudspeaker coupling device 36 can be pivotally mounted so that the loudspeaker device 10, in particular a radiation direction of the loudspeaker device 10, can be flexibly adjusted within an interior of the motor vehicle 34.

[0049] Preferably, it can be provided that the loudspeaker device 10, when coupled to the loudspeaker coupling device 36, is spaced apart from the interior element 38. This has the advantage that the side not facing into the vehicle interior can emit sound waves into the interior of the motor vehicle 34 by means of reflection from the interior element 38, which is schematically illustrated by the arrows. In particular, the previously described pinhole structure can be used for this purpose, which generates a directional characteristic when emitting sound waves. For example, this can be designed such that the sound waves are emitted obliquely to the sides of the loudspeaker device 10, so that they can be better reflected into the interior of the motor vehicle 34 by the interior element 38.

[0050] In Fig.4 shows a further embodiment of the loudspeaker device 10 in the motor vehicle 34 by way of example. In this exemplary embodiment, the interior element 38, i.e., the vehicle door, can have a recess in which the loudspeaker coupling device 36 can be provided. Within this recess, the loudspeaker device 10 can be coupled to the loudspeaker coupling device 36 of the motor vehicle 34, so that a resonance body is provided within the interior element 38. This can improve sound radiation of the loudspeaker device 10. Preferably, the loudspeaker coupling device 36 can have a rail with which the loudspeaker device 10 can be adjusted within the recess.

[0051] Overall, the examples show how the invention can provide a multi-sided, three-dimensional loudspeaker system with identical parts for a loudspeaker device for vehicles.
