Embodiment Construction

[0045] figure 1 A first exemplary embodiment of a multilayer loudspeaker cover 10 according to the invention for covering a loudspeaker 20 is shown schematically in section. The speaker 20 has a speaker body 21 with a membrane for generating sound waves. Furthermore, loudspeaker body 21 has a housing and a driver unit with an electric vibrating coil and magnets. The loudspeaker body is connected to the sound box 21 or the resonance chamber 21 in order to generate sound waves via the diaphragm of the loudspeaker body 21 , which are then emitted into the environment, in particular conductively via the loudspeaker cover 10 according to the invention.

[0046] The loudspeaker cover 10 has a total of four layers 11 , 12 , 13 , 14 , wherein the first layer 11 is a gas-permeable layer and covers as a covering layer the through-openings 15 of the second layer 12 lying below the first layer. The first layer 11 can be designed as a carpet / carpet with textile material or velvet. The t...

Abstract

The invention relates to a multi-layer loudspeaker cover (10) for covering a loudspeaker (20). The loudspeaker cover comprises at least one first layer (11) and a second layer (12), wherein the firstlayer (11) is an air-permeable layer and the second layer (12) is a layer with through-holes (15) for reducing dynamic pressure.

Description

technical field [0001] The invention relates to the field of automobile technology, in particular to a multi-layer loudspeaker cover. The invention also relates to a vehicle. Background technique [0002] The vehicle is equipped with loudspeakers in order to operate an audio system, for example. Speakers in vehicles can also be part of the entertainment system. When the loudspeaker is in operation, the vibration of the loudspeaker also excites the components located in the environment to vibrate as well. However, such vibrations of the components may be perceived by the occupants and sometimes perceived as unpleasant and disturbing. In order to prevent common vibrations of the components, the following solutions have hitherto existed: A decoupling of the vibrations has been sought. [0003] Document DE 10 220 536 C1 describes a loudspeaker assembly having a foam molding which is arranged on a fixed structure in a vibration-damping and sound-damping manner. The foam piec...
