Definitions

  • Embodiments of the present invention relate to a loudspeaker system for a vehicle, in particular with a loudspeaker array, generally to loudspeaker arrays with a plurality of electroacoustic sound transducers in different arrangement configurations and to a loudspeaker array with sound guidance.
  • Future infotainment systems in vehicles and the associated loudspeaker systems in vehicles must be able to cope with demanding tasks in complex traffic scenarios. This requires an absolutely reliable function, whereby dangers in any driving situation for the driver, e.g. due to malfunctions, must be ruled out.
  • communication requirements and fast provision of information as well as undisturbed audio playback play an important role.
  • Interfering signals are not just vehicle noises, but also parallel consumption of different audio content, such as simultaneous phone calls and consumption of media content from the perspective of several passengers.
  • Such challenges require system properties that enable individual sound reinforcement to limited listening areas, so-called sound or listening zones.
  • One example is personalized sound reinforcement (by means of sound zones) by using loudspeakers in the immediate vicinity of the listener's ears in the respective sound zone, eg by integrating loudspeakers into the corresponding headrests of the respective car seat for each listening zone.
  • Such a clustered speaker system is disclosed in the patent U.S. 8,126,159 disclosed.
  • An advantage of this approach is the high acoustic separation from the neighboring sound zones, due to the large difference in listening distance.
  • level reduction with approx. 6 dB per doubling of distance (with ideal spherical wave propagation).
  • a disadvantage of this approach is the high sensitivity to interference, for example as a result of head movements. On the one hand, this leads to strong level fluctuations and significant impairments of spatial perception, e.g. loss of stereo images.
  • a second prior art approach relates to the personalized sound zones that can be created using ultrasonic technology.
  • Audible sound is modulated onto ultrasonic carriers and radiated in a highly focused manner onto the auditory zones.
  • the basic prerequisite for this modulation principle is the emission of very high ultrasonic levels, e.g. greater than 130 dB.
  • the advantage of this approach is that due to the favorable relationship between the wavelength and the size of the active "radiating surface", defined by the size of the loudspeaker or the size of the loudspeaker array, the ultrasound is radiated in a more focused manner than frequencies in the audio frequency range. This enables a higher acoustic separation of the sound zones with the same size of loudspeaker technology used.
  • the disadvantage of this approach is not only that ultrasound can be harmful to health from a certain power level (cf. use of ultrasound in the medical field to destroy kidney stones), but also that the use of ultrasound leads to strong reflections in the vehicle interior, which adversely affect acoustic channel separation. Furthermore, the use of ultrasound requires a high level of power, which is synonymous with low energy efficiency. In addition, there is a strongly non-linear transmission behavior due to the demodulation principle, which results in a low sound quality that is usually only sufficient for speech reproduction.
  • Another prior art approach is based on so-called beamforming.
  • several loudspeakers are used, which are distributed in the vehicle and/or grouped into a loudspeaker array, for example.
  • Targeted control of each loudspeaker results in a directed sound emission, eg for individual sound zones.
  • U.S. 8,073,156 referenced discloses the use of linear speaker arrays in a vehicle. This makes it possible to focus a sound pattern on one or more positions in the vehicle.
  • the patent document U.S. 2012 / 0 121 113 discloses the use of a further loudspeaker array in a vehicle, including the corresponding controller.
  • the advantage over the first approach is the more stable sound zone, even when the head moves.
  • a disadvantage is the sound focusing that can be achieved, which often results in insufficient channel separation, in particular due to the achievable array dimensions, the achievable transducer distances (distance from adjacent electroacoustic transducers) and the number of transducers per array.
  • the channel separation of previous beamforming approaches is reduced by the room acoustic influences in the vehicle, reflections or room modes.
  • U.S. 7,343,020 an automotive audio system with directional, planar sound transducers to generate stereo or surround sounds for each passenger individually.
  • the patent specification US2003/0021433 discloses a speaker configuration together with a signal processor for stereo channel generation for each passenger individually through the use of a center speaker.
  • the EP 1 427 253 A2 shows a loudspeaker system for a vehicle with a loudspeaker array.
  • the JP H05 199595 A D3 shows the installation of sound converters in a vehicle with a plurality of sound guides and sound outlet openings for each sound converter.
  • the object of the present invention is to create a concept for a loudspeaker system, in particular for a vehicle loudspeaker system, which avoids the disadvantages described above and thus enables high-quality surround sound generation with good channel separation.
  • the aim of the invention is to enable space-saving installation.
  • One embodiment includes a speaker system for a vehicle having a speaker array.
  • the loudspeaker array includes a plurality of electroacoustic sound converters that can be controlled individually, so that a user-specific audio signal for different users at different listening positions in a vehicle interior of the vehicle can be reproduced via the plurality of electroacoustic sound converters.
  • the speaker array or in the case of deployed Sound guides a sound outlet of the speaker array is in particular between at least two of the listening positions in the vehicle interior, for example between the driver and the passenger seat, are arranged.
  • a speaker system for a vehicle in particular with regard to channel separation, e.g. when playing different audio content at the different listening positions, can be improved by placing a speaker array centrally in the sense of centered on all or the relevant listening positions.
  • the loudspeaker array used can set up a separate sound cone for each listening position (or each relevant listening position) or, for example, in the case of stereo, several separate sound cones per zone.
  • By arranging the loudspeaker array in the middle, e.g Direction are also oriented in opposite directions, which is optimal in terms of channel separation, especially for user-specific audio playback.
  • a preferred positioning of the loudspeaker array according to the exemplary embodiments would be in the roof liner of the vehicle, in the center console, in the dashboard or in the parcel shelf, it being particularly important according to further exemplary embodiments that there is a distance between the array and the listening positions or at least the relevant listening positions (subset of all listening positions) is essentially the same, ie with a deviating +/- 30%.
  • At least one additional loudspeaker can be provided for each listening position, for example the loudspeaker usually present in the door or the mirror triangle and/or a differently positioned additional loudspeaker.
  • the additional loudspeaker can also be designed as a structure-borne noise converter.
  • the additional loudspeaker is preferably arranged closer to the user than the loudspeaker array. Such a dense arrangement makes it possible for the sound radiated by the additional loudspeaker to be almost negligible in relation to the other listening positions, since one can work here with significantly lower sound levels and large level differences due to the large difference in the listening distance.
  • This additional speaker makes it possible to produce stereo, but also mono with local level boosting or frequency expansion (e.g. bass) for each listening position.
  • Stereo can also be generated using the majority of the electroacoustic sound transducers and the loudspeaker array based on the technique of acoustic beamforming.
  • at least two beams (sound cones) or a stereo beam are generated per listening position.
  • the sound sources it must also be mentioned that it would be conceivable for the sound sources to be generated to be positioned virtually in space with the aid of transfer functions that emulate psychoacoustic effects.
  • the loudspeaker system includes a signal processor which, for example for beamforming, individually controls the electroacoustic sound converter and/or the additional loudspeaker or loudspeakers.
  • the invention creates a loudspeaker array with a plurality of electroacoustic sound transducers which are coupled on their sound emission surface with sound guides for sound output or for sound guidance, each sound guide comprising a sound exit opening.
  • the majority of the sound outlet openings are arranged in such a way that an average distance between the sound outlet openings is smaller than a (possible) average distance between the electroacoustic sound transducers arranged next to one another.
  • FIG. 1a shows a schematically illustrated vehicle interior 10 in plan view with four listening positions 12a, 12b, 12c and 12d, each defined by a seat on which the potential listener can sit.
  • the loudspeaker system 1 for the vehicle interior 10 comprises a loudspeaker array 20, comprising the plurality of electroacoustic sound transducers 20a-20h.
  • the array 20 is arranged relatively centrally in relation to the vehicle interior 10, with the result that the array 20 is arranged at least between two listening positions (subset of all listening positions 12a-12d), here even between the four listening positions 12a-12d is.
  • Possible installation spaces for the loudspeaker array are, for example, the roof liner, the center console, but also alternatively the dashboard or rear shelf.
  • the loudspeaker array 20 can be installed above or below or even at the level of the listening zones 12a-12d or the ear level of the listener.
  • the term centrally refers to all listening zones 12a-12d or at least to a subset of the listening zones 12a-12d, eg listening zones 12a and 12b. The functionality of the loudspeaker system realized in this way for the vehicle is discussed below.
  • the loudspeaker array forms a sound lobe 22a-22d for each listening position 12a-12d, which is preferably aligned with the listening zones 12a-12d or at least assigned to them.
  • the formation of these sound cones 22a-22d takes place in that the sound transducers 20a-20h of the loudspeaker array 20 are controlled differently, for example taking into account so-called beamforming algorithms, which can also include the radiation characteristics of the individual transducers 20a-20h and the room acoustic influences.
  • beamforming algorithms can also include the radiation characteristics of the individual transducers 20a-20h and the room acoustic influences.
  • the loudspeaker array 20 is designed to construct a separate sound cone 22a-22d for each listening position 12a-12d, with each sound cone 22a-22d being directed in opposite directions (from the center to the listening positions 12a- 12d) is oriented.
  • the loudspeaker array 20 is approximately equidistant from each listening position 12a-12d, so that each sound lobe 22a-22d has similar characteristics (e.g. extent and level). .
  • These two properties contribute significantly to the achieved channel separation between the channels 22a-22d.
  • An advantage of the sound lobes 22a-22d generated by means of beamforming is that the channel separation is so good that user-specific audio signals can be generated for the listening zones 12a-12c.
  • the arrangement shown even satisfies a second optional specification, namely that the distance between the loudspeaker array 20 and the individual listening positions 12a-12d is essentially the same, ie with a tolerance of +/- 30% (central arrangement).
  • the central position of the array 20 also reduces disruptive influences of the room acoustics with regard to the sound zones, for example as a result of sound reflections on side windows.
  • a sound outlet of a sound guide (cf. 3 ) coupled to the speaker array may be positioned centrally or generally between at least two of the listening zones 12a-12d.
  • the sound guide typically includes a sound conductor coupled to the respective sound transducer 20a- 20h for each sound transducer 20a- 20h, with a plurality the sound outlets of the sound conductors form the sound outlet of the sound guide.
  • the actual sound transducer array 20 can then be accommodated at a suitable location in the car (for example in the trunk), for example for reasons of space, and the sound guide can guide the sound to the corresponding central sound outlet point.
  • loudspeaker arrays With loudspeaker arrays arranged in this way, it is also possible to generate stereo or even 3D surround sound for each listening position 12a-12d, as referred to in FIG Fig. 1b is shown.
  • Fig. 1b shows the top view of the vehicle interior 10 with the four listening positions 12a-12d and the loudspeaker array 20 of the loudspeaker system 1.
  • the generation of stereo is explained using the position 12a, but can also be transferred to the other listening positions 12a-12d.
  • a double sound lobe comprising sound lobes 22aL and 22aR is generated for listening position 12a.
  • the sound beams 22al and 22ar are aimed at the left ear (22aL) and at the right ear (22aR) of the listener at the listening position 12a.
  • the generation of sound channels per listening position 12a-12d is not limited to the number 2 for stereo. Rather, several sound cones per listening position 12a-12d can be generated in order to simulate spatial sound, for example.
  • transfer functions which emulate psychoacoustic effects are taken into account in order to better position the virtual sound sources in the interior 10 be able. Examples of such transfer functions are HRTF functions and/or Blauert bands.
  • the sound cones 22aL, 22aR, 22b, 22c and 22d, depending on the seating position, which is the listening position 12a, 12b, 12c and 12d are aligned.
  • An informational coupling of the loudspeaker system to the (electrical) seat adjustment would be conceivable here, for example.
  • FIG. 1c and 1d Another embodiment of the speaker system is in 1c and 1d disclosed, in which the central loudspeaker array 20 is combined with at least one additional loudspeaker or additional loudspeaker array (or generally with an additional loudspeaker system comprising at least one additional loudspeaker). Possible positions for the additional loudspeaker(s) are the A, B, C pillars, the headrest or the roof liner.
  • 1c shows the vehicle interior 10 (top view) with the four listening positions 12a-12d, the centrally arranged loudspeaker array 20 of the loudspeaker system 1', with the first listening position 12a being assigned an additional loudspeaker 30a (here e.g. in the roof liner, alternatively B-pillar or headrest). is.
  • this additional loudspeaker 30a is located at the listening position 12a on a side facing away from the loudspeaker array 20 (here on the left) and is preferably but not necessarily arranged closer to the ear than the central loudspeaker array 20 ensures that a further optional condition, namely that the additional loudspeaker 30a is arranged closer to a listening position 12a compared to the other listening positions 12b-12d, is met.
  • the additional loudspeaker 30a generates a sound lobe 32aL, which is assigned a listening position 12a to one (left) ear of the listener, while the other (right) ear is irradiated by the sound lobe 22aR (generated by the loudspeaker array 20). It is thus possible in the exemplary embodiment shown to generate stereo at the listening position 12a.
  • the use of the additional loudspeaker 30a is not limited to stereo, so the additional loudspeaker 30a can generally serve to support the sound reinforcement at the listening position 12a (mono with level boost).
  • the additional loudspeaker 30a is positioned close to the listening position, so that the laws of the sound level drop with distance are exploited, which means that the sound level of the additional loudspeaker 30a in the associated listening zone 12a is louder than in the foreign listening zones 12b-12d. This primarily contributes to the increased acoustic separation of the sound zones 12a-12d.
  • the advantages of one of the additional loudspeakers 30a can be seen in the fact that the sound quality and the spatial impression for the associated sound zone can be improved by utilizing psychoacoustic effects be improved.
  • arranging sound transducers 20 or 30a as close as possible to the listening position (here 12a), cf. e.g. sound transducers 20 and 30a in relation to listening position 12a, increases the proportion of direct sound, so that reflections are largely covered or are negligible.

  • structure-borne sound converters 35b and 35d are particularly suitable as support in the low-frequency range, in which sound reproduction with small arrays (because of the limited array size) would not be able to be focused sufficiently.
  • Optional sound decoupling means can ensure that the structure-borne sound 36d or 36b cannot be heard in other auditory zones, eg 12a and 12c, which in turn contributes to increasing the acoustic separation between the sound zones 12a-12d.

  • each line array can in itself comprise different sound transducer types, the combination of line arrays with one type per line array being preferable.
  • An exemplary embodiment is characterized in that two line arrays with acoustic transducer type A enclose three line arrays with acoustic transducer type B. A flat loudspeaker array is then formed in which a specific type of sound transducer is concentrated in the center.
  • FIG. 3 shows a loudspeaker array 90, designed here as a combination of eight sound transducers 52a-52h of the same type.
  • Each of these sound converters 52a-52h or, to be precise, the membrane 56 of the sound converters 52a-52h is coupled to a sound guide 92a-92h on its emission side.
  • These sound guides 92a-92h are funnel-shaped and optionally curved elements, so that the sound outlet openings (see reference number 94) of the sound guide 92a-92h are smaller (in all or at least one dimension) than the sound inlet openings (see reference number 56) on the side of the electroacoustic sound transducers 52a-52h.
  • the funnel of the sound guide 92a-92h is designed in such a way that the sound inlet 56 is offset compared to the sound outlet openings 94, with a different offset ratio being used depending on the combination with a sound transducer 52a-52h, so that the total area of the sound outlet openings can be reduced overall .
  • the sound outlet openings 94 of the sound guides 92a-92h can be arranged close together with a mean distance d S .
  • a very small average distance d S between the sound outlet openings 94 (especially in comparison to the average distance d A ) is achieved, which leads to an improved adjustable directional characteristic (due to the reduction in the sound emission area through the compact Distance d S of the sound outlet openings 94 or due to the reduced virtual sound transducer distance d S ) and better positioning of the array (eg in the vehicle) contributes.
  • the combination of the sound guide 92a-92h with one of the loudspeaker arrays 50, 60, 70 or 80 is possible, so that the sound guide can also be used for the exemplary embodiments of the loudspeaker system 1, 1′ or 1′′ from the figs 1a-1d it is a possibility. It is then also possible (as already indicated above) to design the sound guide 92 in such a way that the actual sound transducer array 90 (or also 50, 60, 70, 80), e.g. for reasons of space, can be installed at a suitable point in the car (e.g is housed in the trunk) and the sound guide 92 leads the sound to the corresponding sound outlet point, for example in the roof, which enables space-saving installation.
  • the loudspeakers or loudspeaker arrays of the loudspeaker system can also be arranged with a predetermined orientation, for example to the listening positions 12a-12d, so that a directed radiation per sound transducer is possible, which reduces the influence on the room acoustics in the sound zones by the position of the loudspeakers.
  • a signal control device can also be created which controls the array 20 or the extended arrays 50, 60, 70, 80, 90 according to the principles described above (cf. mono reproduction of the listening zone 12a-12d or stereo reproduction of the listening zone 12a-12d). controls and thus allows the formation of the corresponding number of highly focused sound radiation beams 22a-22d, 22aL, 22aR.
  • the user-specific signals can also be understood to mean the display of other audio information, such as in infotainment signals or telecommunications audio in a specific listening zone, eg the driver's listening zone 12a.
  • the speaker system may include a crossover network or a processor configured to add the input signal, if it comprises only listening content (ie content for a person at a respective listening/sitting position), the middle and higher frequencies to the array , For example, in such a way that beam forms can be operated, provide and output the low frequencies to the structure-borne noise transducer of the respective seating position.
  • listening content ie content for a person at a respective listening/sitting position
  • the middle and higher frequencies For example, in such a way that beam forms can be operated, provide and output the low frequencies to the structure-borne noise transducer of the respective seating position.
  • the audio content to be reproduced comprises several parallel contents, e.g.
  • the crossover network or the audio processor is designed to provide the middle and higher frequencies of all audio content to be reproduced to the array, specifically in the way that the audio content is reproduced separately for the different listening zones at the different listening positions using beamforming, while the lower frequencies are split off and forwarded separately to the different structure-borne sound transducers in the different seats or listening positions. All in all, this offers the advantage that medium and higher frequencies for the various listening positions are reproduced in a directed manner by means of the array, while the low frequencies are only represented locally via the structure-borne sound transducer.
  • the background to this approach is that the low frequencies in particular cannot be directed so well via arrays, so that separating them using beamforming often causes difficulties.
