Description

本発明は、特許請求項１の前文においてより具体的に定義される型式の自動車内の音を修正するための装置に関する。   The present invention relates to a device for modifying the sound in a motor vehicle of the type more specifically defined in the preamble of claim 1.

一般的な型式の装置が特許文献１に記載されている。このような装置では、特に加速中に、一方ではより集中した運転体験を可能とし、他方では内燃機関の負荷状態に関するより多くの情報を伝えるために、内燃機関によって生じる音を自動車の運転者により強く伝達することが意図されている。   A common type of device is described in US Pat. With such a device, the sound produced by the internal combustion engine can be heard by the vehicle driver, especially during acceleration, to allow a more focused driving experience on the one hand and on the other hand to convey more information about the load condition of the internal combustion engine. It is intended to communicate strongly.

しかし、この公知の装置の欠点は、その比較的低い効率および極めて柔軟性のない伝達特性にある。   However, the disadvantage of this known device lies in its relatively low efficiency and extremely inflexible transmission characteristics.

特許文献２において、装置の全体のこの効率を改良することが試みられた。しかし、ここでも、特により柔軟な伝達特性に関して、最適の解決策はやはり提案されていない。   In U.S. Pat. No. 6,057,059, attempts were made to improve this overall efficiency of the device. However, here too, no optimal solution has been proposed, especially with regard to more flexible transmission characteristics.

独国特許出願公開第４４３５２９６Ａ１号明細書German Patent Application Publication No. 4435296A1 独国特許出願公開第１００４２０１２Ａ１号明細書German Patent Application No. 10042012A1

従って、本発明の目的は、自動車内の音を修正するための装置であって、内燃機関によって生じた音を簡単な手段によって伝達することができ、伝達特性の改良を達成することを全体的に意図する装置を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is an apparatus for correcting sound in an automobile, which can transmit sound generated by an internal combustion engine by simple means, and achieves improvement of transmission characteristics as a whole. It is to provide an intended device.

この目的は、本発明によれば、特許請求項１に記載の特徴によって達成される。   This object is achieved according to the invention by the features of patent claim 1.

本発明による出口ラインの分岐であって、そこから延在する少なくとも２つの分岐ラインを有する分岐は、装置の中空体内において生成または強調された音を自動車内または自動車上の種々の位置に導くことができる。これは、自動車の乗員に対して音を生じさせる方法を、例えば、車両の型式または購買者の要求に依存して、変更させる多種多様な可能性をもたらす。   A branch of an exit line according to the invention, having at least two branch lines extending therefrom, directs the sound generated or emphasized in the hollow body of the device to various locations in or on the vehicle Can do. This offers a wide variety of possibilities to change the way the sound is generated for the vehicle occupant, for example depending on the type of vehicle or the requirements of the purchaser.

音または信号の強調は、本発明によれば、異なる位置に繋がる分岐ラインによって達成され、さらに三次元音響をもたらす。   Sound or signal enhancement is achieved according to the present invention by branch lines leading to different locations, further resulting in three-dimensional sound.

本発明の有利な改良形態および発展形態は、従属請求項およびその原理が図面に基づいて記載される以下の例示的実施形態によって、提供される。   Advantageous refinements and developments of the invention are provided by the following exemplary embodiments whose dependent claims and their principles are described on the basis of the drawings.

概略的にしか示されていない内燃機関２のガス運搬ライン１、すなわち、例えば、吸気ラインまたは排気ラインに、入口ライン３を介して、取り付けられているのは、内燃機関２の音を修正するための装置４であり、その基本的構造と操作モードは、例えば、独国特許出願公開第１００４２０１２Ａ１号明細書に記載されている。ガス運搬ライン１、内燃機関２、および入口ライン３と同様、装置４は自動車（全体図示省略）に配置され、自動車の室内空間５および自動車の周囲における両方の音に影響を及ぼすことができる。   It is attached to the gas transport line 1 of the internal combustion engine 2, which is shown only schematically, that is, for example, to the intake or exhaust line, via the inlet line 3, to correct the sound of the internal combustion engine 2. The basic structure and operation mode of the device 4 are described in, for example, DE 10042012A1. Similar to the gas transport line 1, the internal combustion engine 2 and the inlet line 3, the device 4 is arranged in an automobile (not shown) and can affect both the interior space 5 of the automobile and the sound around the automobile.

この目的のために、装置４は、この場合、振動可能なガス不浸透性薄膜７として形成されている音響伝達手段によって２つの空間、すなわち、入口空間８および出口空間９に分割される中空体６を有している。入口空間８は、この場合、入口ライン３に接続され、出口空間９は出口ライン１０に接続されている。圧力サージまたは圧力差によってガス運搬ライン１に生じる音は、入口ライン３を介して中空体６の入口空間８に導かれ、それによって、薄膜７が作用し、振動を引き起こす。このように作用するとき、薄膜７は典型的な自然周波数で振動し、出口空間９内に存在する空気によって出口ライン１０内に伝達される。前述したように、薄膜７は、ガス運搬ライン１から出口ライン１０内にガスが溢れ出すのを防ぐために、ガス不浸透性材料からなる。   For this purpose, the device 4 is in this case a hollow body which is divided into two spaces, namely an inlet space 8 and an outlet space 9 by means of acoustic transmission, which are formed as a gas-impermeable thin film 7 that can vibrate. 6. The inlet space 8 is in this case connected to the inlet line 3 and the outlet space 9 is connected to the outlet line 10. Sound generated in the gas carrying line 1 due to pressure surge or pressure difference is guided to the inlet space 8 of the hollow body 6 through the inlet line 3, whereby the thin film 7 acts and causes vibration. When acting in this way, the membrane 7 vibrates at a typical natural frequency and is transmitted into the outlet line 10 by the air present in the outlet space 9. As described above, the thin film 7 is made of a gas-impermeable material in order to prevent gas from overflowing from the gas carrying line 1 into the outlet line 10.

出口ライン１０は分岐１１を有し、この場合、そこから２つの分岐ライン１２および１３が自動車の室内空間５に延びている。その結果、音響伝達装置、すなわち、薄膜７の記載された振動を自動車の室内空間５における多数の位置に導くことができ、また、２つの分岐ライン１２および１３を示されていない方法で自動車の周囲の空間に繋げることもできる。分岐ライン１２および１３が室内空間５内に開いている位置は、例えば、運転者の足下空間および同乗者の足下空間であってもよく、それによって、運転者および同乗者が同一の音響感覚を知覚することを可能にできる。   The outlet line 10 has a branch 11 from which two branch lines 12 and 13 extend into the interior space 5 of the automobile. As a result, the described vibrations of the acoustic transmission device, i.e. the membrane 7, can be guided to a number of positions in the interior space 5 of the vehicle, and the two branch lines 12 and 13 are not shown in a manner not shown. It can also be connected to the surrounding space. The position where the branch lines 12 and 13 are opened in the indoor space 5 may be, for example, the driver's foot space and the passenger's foot space, whereby the driver and the passenger have the same acoustic sensation. It can be perceived.

このようにして、内燃機関２のドライブ音、すなわち、運転音に依存する三次元騒音を自動車の室内空間５内に生じさせ、自動車の運転者に内燃機関２の負荷状態に関する音響情報を与え、同時に音響の三次元知覚をもたらす。これに関連して、分岐１１から分岐する極めて多数の分岐ライン及び／又は極めて多数の分岐１１を出口ライン１０内に設けることもできる。   In this way, the driving sound of the internal combustion engine 2, that is, three-dimensional noise depending on the driving sound is generated in the interior space 5 of the automobile, and the acoustic information regarding the load state of the internal combustion engine 2 is given to the automobile driver, At the same time, it provides a three-dimensional perception of sound. In this connection, a very large number of branch lines and / or a very large number of branches 11 branching off from the branch 11 can also be provided in the outlet line 10.

２つの分岐ライン１２および１３の出口に、すなわち、この場合、室内空間５内へのそれらの遷移部に、音響インピーダンスを加えることによって音響パターンの変化を生じさせる吸収材料１４および１５がそれぞれ配置されている。   Absorbing materials 14 and 15 are respectively provided at the outlets of the two branch lines 12 and 13, i.e. in this case at their transitions into the interior space 5, causing an acoustic pattern change by applying an acoustic impedance. ing.

さらに、示された例示的実施形態において、２つの分岐ライン１２および１３は、２つの分岐ライン１２および１３に干渉を生じさせる、異なる長さを有し、それによって、異なる干渉パターンが生成され、出口ライン１０内を伝達される音の特定の周波数が低減され、他の周波数が強調される。   Further, in the illustrated exemplary embodiment, the two branch lines 12 and 13 have different lengths that cause interference to the two branch lines 12 and 13, thereby generating different interference patterns, Certain frequencies of the sound transmitted through the exit line 10 are reduced and other frequencies are emphasized.
