Definitions
- the invention relates to a speaker in the support structure of a motor vehicle according to the preamble of patent claim 1.
- a sound system e.g. a radio, a cassette player and a CD player.
- a better sound system includes a speaker system that has tweeters and woofers.
- the speakers emit their sound towards the vehicle interior, they are, in order to avoid interference problems, connected to a resonant volume, which is not connected to this interior.
- a resonant volume which is not connected to this interior.
- loudspeakers special cavity volumes, so-called loudspeakers, in suitable locations of the vehicle, which, however, usually leads to a reduction of the available loading space volume of the motor vehicle or claimed volumes in the door trim.
- German published patent application DE 197 35 082 A1 in order to increase the resonant volume associated with a loudspeaker, the coupling of a small loudspeaker box with a low resonance volume under the driver's seat to a larger void volume already present in the motor vehicle (threshold volume) is described.
- the small speaker and the wall the void volume over a coordinated opening.
- the loudspeaker box In order to achieve an acoustic coupling of the two resonance chambers, the loudspeaker box must be mounted precisely on the wall of the cavity volume, so that through the openings of the wall and the loudspeaker box for a passage of sound lie on each other.
- the object of the invention is to provide a in cooperation with the support structure of a vehicle speaker, which has good acoustic properties and can be realized without much mechanical design effort.
- an active transducer is introduced and positioned so that connect to each of its two sides of the membrane separate subspaces.
- these two subspaces are formed by the volume of the cavity of at least one element of the support structure of the vehicle.
- a tunnel in the wall of at least one of the elements is provided, via which at least part of the sound waves generated by the sound transducer in the subspaces is introduced into the interior of the vehicle.
- the two subspaces of the speaker are formed by at least two elements of the support structure of the vehicle.
- the sound transducer is integrated into an area in which two elements of the support structure meet.
- Characterized in that the total volume of the speaker is formed by a combination of several elements of the support structure is advantageously a qualitative high-quality reproduction of low-frequency sound (bass) possible.
- the choice of the installation location of the sound transducer in the region of the meeting of two elements of the support structure allows a structurally and economically favorable positioning; For example, it is conceivable to provide the transition areas of the elements, which are anyway to be designed individually in the vehicle design, with omissions suitable for installing a shutter converter. It is also conceivable to make the transition regions accessible for mounting the sound converter.
- the separation of the elements of the support structure in the subsequent to the two membrane sides of the transducer subspaces of the speaker can, depending on the dimensions of the elements only by a matched to these dimensions speaker basket, in which the transducer is integrated done.
- FIG. 1 shows an element of the support structure that is typically located in a vehicle and is connected to one another;
- FIG. 2 shows a loudspeaker box according to the invention, which uses the volume of three interconnected elements of the support structure,
- FIG. 3 shows an alternative embodiment of the loudspeaker box from FIG. 2 with limited volume circumference and filling material in the closed subspace.
- Figure 1 shows an example of a vehicle (1) with typical elements (2,3,4,5,6) of the support structure; here threshold volume (2), cross member (3) and longitudinal members (4), and Biegequerthen (5) and a front cross member (7).
- threshold volume (2) typical elements
- cross member (3) cross member (3)
- longitudinal members (4) and Biegequerthen (5)
- Biegequerthen (5) and a front cross member (7).
- the total volume of the speaker is formed by the threshold volume (2), the cross member (3) and the longitudinal member (4).
- the sound transducer (10) is introduced between the cross member (3) and the longitudinal member (4).
- the sound transducer (10) in its dimensions, in particular by suitable design of the speaker basket, so adapted to the dimensions of the support structure that it divides the total volume into two separate subspaces.
- a first, closed subspace is formed by the longitudinal member (4), while the second subspace consists of the common volume of the acoustically coupled cross member (3) and sill (2). This subspace is coupled via a tunnel (11) with the surroundings of the sill.
- the sound generated by means of the sound transducer (10) would be emitted via the tunnel (11) into the interior of the vehicle.
- the opening area of the tunnel (11) should be about one fifth, but at least one tenth of the effective membrane area of the sound transducer (10).
- the separation of the two subspaces by suitable dimensioning of the sound transducer (10) and its speaker basket it is as it were Of course, it is conceivable to separate the total volume formed by the elements (2, 3, 4) by a dividing wall into two partial spaces, and to introduce the sound transducer (10) into this dividing wall.
- FIG. 3 shows an alternative embodiment of the loudspeaker box from FIG. 2.
- insulating material (13) was introduced into the closed subspace formed by the longitudinal carrier.
- the closed subspace is at least half filled with acoustic insulation material (13).
- the tunnel (11) relative to the vehicle compartment open subspace, here by the cross member (3) and the sill (2) formed at least partially provided on its walls with insulating material. The fact that only the walls are provided with insulating material, it is achieved that as little sound energy is swallowed and the bass can be contoured.
- the volume of the sill (2) available for the loudspeaker box has been limited by introducing a partition wall (12).
- a partition wall (12) By means of such a design measure can be achieved in a simple manner that the two separate on the two sides of the membrane transducer (10) adjacent subspaces have substantially the same order of magnitude, so that a similar sound pressure on both sides of the diaphragm of the transducer (10).
- the resonant volume of the loudspeaker can also be increased by the fact that at least some of the elements forming the subspaces (2,3,4,5,6) of Support structure via diffusion openings with the environment of the vehicle (1) are connected.
