Problems solved by technology

However, the problem here is that when the loudspeaker system is not in operation, undesired noise, for example from the engine compartment, can enter the passenger compartment of the motor vehicle, since the loudspeaker membrane does not provide sufficient sound insulation

Embodiment Construction

[0020] figure 1 Loudspeaker system 1 for a motor vehicle, not shown in its entirety, is shown. For this motor vehicle, only the engine compartment 2 (that is to say the space in which the not-shown internal combustion engine of the motor vehicle is arranged), the passenger compartment 3 and the end wall 4 separating the passenger compartment 3 from the engine compartment 2 are shown. For the loudspeaker system 1 , a loudspeaker 5 is shown in this exemplary embodiment, which is arranged outside the passenger compartment 3 in a so-called water tank 6 of the motor vehicle, which is separated from the engine compartment 2 by a wall 7 . The loudspeaker 5 is connected to the passenger compartment 3 by means of a line 8 , a part 8 a of which extends through the end wall 4 . The sound produced by the loudspeaker 5 is transmitted into the passenger cabin 3 in this way, so that the sound can reach the passengers located in the passenger cabin 3 . A portion 8b of the line 8 also extend...

Abstract

The invention relates to a loudspeaker system (1) for a motor vehicle, which has at least one loudspeaker (5), which is arranged outside the passenger compartment (3) of the motor vehicle and is connected to the passenger compartment (3) by means of at least one line (8). 3) Acoustically connected, characterized in that at least one sound-absorbing device (9) is connected to said at least one pipeline (8) leading from said at least one loudspeaker (5) to the cabin (3) and / or to another A conduit (8) connected to said at least one loudspeaker (5) is connected.

Description

technical field [0001] The invention relates to a loudspeaker system for a motor vehicle having at least one loudspeaker which is arranged outside the passenger compartment of the motor vehicle and is acoustically connected to the passenger compartment by means of at least one line. Background technique [0002] Loudspeaker systems of this type are known from the general prior art. Due to the limited installation space conditions, the loudspeaker is positioned outside the interior or passenger compartment of the motor vehicle, and the sound waves generated are conducted via lines into the passenger compartment. The problem here, however, is that when the loudspeaker system is not in operation, unwanted noise, for example from the engine compartment, can penetrate into the passenger compartment of the motor vehicle, since the loudspeaker membrane does not provide sufficient sound insulation. [0003] JP 64 014548U discloses a loudspeaker system which is positioned in the tru...
