Definitions
- the invention relates to a device for noise design in a motor vehicle according to the kind defined in the preamble of claim 1.
- a generic device is known from DE 44 35 296 AI. Such devices are intended to provide the driver of the motor vehicle, particularly when accelerating, with increased transmission of the noises generated by the internal combustion engine, on the one hand to enable a more intensive driving experience and on the other hand to pass on more information about the load state of the internal combustion engine.
- the output line according to the invention By branching the output line according to the invention with the at least two branch lines extending therefrom, it is possible to direct the noises generated or amplified within the hollow body of the device to different locations in or on the motor vehicle. This results in a wide variety of options for changing the generation of noise for the occupants of the motor vehicle, for example depending on the type of vehicle or also at the request of the buyer.
- noise or signal amplification is achieved in that the branch lines lead to different locations, which also leads to a spatial sound.
- the single figure shows a schematic representation of the device for noise design according to the invention.
- a device 4 for designing the noise of the internal combustion engine 2 is attached via an input line 3, the basic structure and mode of operation of which are described, for example, in DE 100 42 012 AI can be known.
- the device 4, like the gas-carrying line 1, the internal combustion engine 2 and the input line 3, is not shown in its entirety in a set motor vehicle and is able to influence both the noise in an interior 5 of the motor vehicle and in the vicinity thereof.
- the device 4 has a hollow body 6, which is divided into two rooms, namely an input room 8 and an output room 9, by a sound transmission device designed in the present case as an oscillatable, gas-tight membrane 7.
- the input space 8 is connected to the input line 3, whereas the output space 9 is connected to an output line 10.
- the noises caused by pressure surges or pressure differences in the gas-carrying line 1 are introduced via the input line 3 into the input space 8 of the hollow body 6, as a result of which the membrane 7 is acted upon and excited to vibrate.
- the membrane 7 vibrates at a natural frequency which is typical of it and which is passed on to the output line 10 by the air in the output space 9.
- the membrane 7 consists of a gas-tight material in order to prevent gases from flowing over from the gas-carrying line 1 into the outlet line 10.
- the output line 10 has a branch 11, from which in the present case two branch lines 12 and 13 continue to the interior 5 of the motor vehicle.
- the two locations at which the branch lines 12 and 13 open into the interior 5 can be, for example, the driver's footwell and the front passenger's footwell. It is ensured that the driver and the passenger experience the same sound impression.
- a spatial noise is generated in the interior 5 of the motor vehicle, which depends on the driving noise or the operating noise of the internal combustion engine 2 and thus provides the driver of the motor vehicle with acoustic information about the load state of the internal combustion engine 2 and at the same time conveys a spatial sense of sound.
- a larger number of branch lines to branch off from the branch 11 and / or for a larger number of branches 11 to be provided in the output line 10.
- the two branch lines 12 and 13 are of different lengths, which leads to interference in the two branch lines 12 and 13, as a result of which different interference patterns arise and individual frequencies of the noise transmitted through the output line 10 are reduced and others are amplified.
