- the membrane 4 is sound-absorbing.
- the rigidity and / or their connection to the housing 2 selected is that prevailing in an interior 8 of the housing 2 Sound the wall or membrane 4 can excite vibrations. These vibrations are symbolic by a double arrow 9 shown. Due to the vibration excitation of the membrane 4 energy is extracted from the sound, causing the Sound emissions to the environment 7 reduced accordingly.
- this membrane 4 i.e. their sound absorbing Effect with respect to certain frequencies or Frequency bands and the intensity of sound absorption, depends on various measures. For example, make up the rigidity or elasticity of the membrane 4 and their Mass important influencing factors.
- the housing 2 is preferably made of several housing parts 2a and 2b and optionally 2c formed. These housing parts 2a to 2c are preferably friction welded together, these friction welded joints symbolic are shown and designated 10.
- the membrane 4 separates Interior 8 of the housing 2 from a cavity 11, the gas volume, especially includes an air volume.
- This closed gas volume acts like a spring with the Membrane 4 together, whereby their vibration property and thus their damping effect is influenced.
- By choice of the volume of this cavity 11 and the one prevailing therein Pressure can dampen the effect on certain frequencies or frequency bands can be set.
- a sound-absorbing can be in this cavity 11
- Substance 12 can be introduced.
- This substance 12 consists preferably of an open-cell foam or made of glass wool and causes a change in the spring properties of the air volume in the cavity 11 and thus an influence the damping effect of the membrane 4.
- the entire Cavity 11 filled by the sound absorbing material 12 be, whereby the membrane 4 on the cavity 11 facing Side supported on the fabric 12. This measure too causes a change in the sound damping effect the membrane 4.
- the wall section assigned to the cavity 11, here in a Bottom 13 at least one opening 14 may be included through which the cavity 11 communicates with the environment 7.
- the present Embodiment are three openings 14 in the Bottom 13 introduced. This measure also causes a change the damping behavior of the membrane 4. It is clear that the measure shown in Fig. 4 also in the corresponding other embodiments of the other figures additionally can be used.
- the membrane 4 in another Embodiment can also be designed so that they are does not extend over the entire cross section of the housing 2, whereby also the vibration behavior and thus the damping effect of the membrane 4 can be changed can.
- FIG. 6 a horizontal installation the membrane 4 shows, in the embodiment according to FIG. 7 shows a vertical arrangement of the membrane 4.
- a plurality of membranes 4 can be arranged in the housing 2, which are also different can be trained. By this measure can also affect the damping effect of the membrane assembly become.
- the Membrane 4 an outer wall of the housing 2. Also this embodiment differs for example from that in Fig. 1 shown embodiment with regard to their damping behavior.
- FIG. 9 shows a further development of that shown in FIG. 8 Embodiment in which a mass element 15 with the Outer wall forming membrane 4 is coupled.
- This coupling takes place here via coupling members 16, which have a spring action and / or can have a damping effect.
- two coupling elements 16 shown can also be a single one Coupling member for connecting the mass element 15 with the membrane 4 are sufficient.
- the one shown in Fig. 9 Embodiment is the mass element 15 as a heat shield formed, which consists for example of a metal and the housing 2 from dangerous heating protects.
- This heat shield or mass element 15 is arranged so that it is movable relative to the housing 2 is held on the membrane 4, so that the membrane 4 also excite the plate serving as mass element 15 to vibrate can.
- the absorption effect of the membrane 4 is thereby influenced.
- Another effect is the effect of Coupling links 16 added.
- an open-cell foam 17 in the Injected housing has one of the interior of the housing 8 exposed surface 18 by a corresponding manufacturing step is skinned, whereby the foam 17 is a substantially closed-pore Receives skin, which then forms the membrane 4.
