Definitions
- the present invention relates to a loudspeaker system with a plurality of sound transducers which are fastened in or behind sound passage openings in a carrier plate.
- LautSprecherSysteme are used in both private and commercial areas to achieve certain sound effects.
- Multi-channel technology in the audio sector in particular requires the use of an ever increasing number of speakers. This poses increasingly greater problems for the user with regard to the arrangement and placement of the loudspeakers, since the aesthetic aspect of integrating the loudspeakers in the room generally also plays an important role.
- picture loudspeakers are offered that can be attached to the wall like a picture due to their flat design and optical design.
- a disadvantage of such picture loudspeakers, however, is that they cannot be placed consistently as the specification for the intended sonic
- box-shaped wall elements with built-in loudspeakers are installed in the hall, which provide suitable additional sound.
- the wall elements are constructed in a comparable way to conventional loudspeakers, but without sound openings, since the front plate of the wall elements directly serves to emit sound.
- US 3992586A shows a sound amplification system for conference rooms, which in one embodiment comprises a speaker system in a separate housing, which is attached to the ceiling.
- the loudspeakers are arranged behind sound through openings in the housing.
- DE 100 01 410 AI describes a flat loudspeaker arrangement with a plurality of plate loudspeakers which are lined up seamlessly like tiles on one
- the ceiling element consists of a plate-shaped component with transducers, which form a plate loudspeaker, the plate-shaped component being held under tension with a box-shaped tensioning device which also serves to suspend the ceiling element.
- the loudspeaker is used directly as a ceiling element with the tensioning device.
- the object of the present invention is to provide a loudspeaker system which offers greater freedom with regard to the number and arrangement of the individual sound transducers, without disturbing the aesthetics of the room in which the loudspeaker system is used.
- the present loudspeaker system consists in a known manner of several sound transducers which are fastened in or behind sound passage openings of a carrier plate.
- the present loudspeaker system is characterized in that the support plate is designed as a wall plate for interiors or external facades of buildings and the sound transducers are integrated in the support plate so that they do not have protrude the back of the carrier plate.
- Any known loudspeaker types such as dome loudspeakers or flat loudspeakers, can be used as sound transducers.
- the loudspeaker wall plate formed in this way at least consisting of the wall plate with the sound passage openings and the sound transducers, combines the audio technology with the construction technology.
- the speaker wall plate is installed in drywall on a substructure made of metal, wood or the like, as is the case with known wall plates for interiors, which usually consist of plasterboard.
- the present loudspeaker wall plate can be used for the new construction of walls or can also be applied to existing walls.
- the rooms can only be covered with such loudspeaker wall panels or formed from these, or only partially contain such loudspeaker wall panels at the desired locations.
- a room clad or constructed in this way with one or more loudspeaker wall panels can thus directly contain a multichannel audio playback system without having to set up separate loudspeaker boxes in the room.
- the preferred embodiment of the present loudspeaker system provides wall panels for interior spaces of buildings as support panels, it is of course also possible to use suitable wall panels for exterior facades of buildings
- the present loudspeaker system hereinafter also referred to as the loudspeaker wall plate, as in the previous sections, is used primarily in event rooms, in cinemas and in the home (living room, TV room).
- the wall plate preferably already has dimensions of at least 250 x 60 cm (height x width), so that it can easily be used for normal room heights.
- the entire surface of the wall plate is preferably covered by an optically appealing film or an optically appealing fabric so that the individual sound transducers of the wall plate remain invisible. They are part of the walls that make up the room. In the present loudspeaker system, the cabling of the individual sound transducers takes place on the
- the present loudspeaker system can be used advantageously for the reproduction of sound sources after wave field synthesis, since a minimum number of six loudspeakers per meter of wall width can be easily integrated into the wall panels. Even with this configuration, the overall aesthetic impression of the room is not disturbed when using the present loudspeaker system, since all of them
- Sound transducers are integrated in the walls of the room and remain invisible to the user in the preferred embodiment.
- the connections for the loudspeaker system are preferably arranged as a separate connection panel in an area of the front of the wall plate, preferably in a lower edge area when the wall plate is installed as intended. This connector panel can then be covered by appropriate baseboards or decorative profiles that allow internal routing of the connection cables.
- the required audio amplifiers are also integrated into the wall plate in analog or digital technology together with all the necessary means for controlling the individual sound transducers or fastened to the rear side thereof.
- only connections for the supply of the corresponding audio data for example from a multimedia system or a CD or DVD player with a digital preamplifier, are required to the amplifiers.
- the wall panels are preferably treated on the front surface in such a way that they can be set up as wall elements without further finishing or applied to existing walls as additional cladding. This can also be achieved, for example, by using the above-mentioned film or fabric. A final treatment like plasterboard is not necessary. This results in much shorter installation times, whereby the wall panels can be shortened to different room heights at any time. It goes without saying Different surfaces, ie surfaces in different designs and colors, are offered to meet the wishes of the user. The transport and storage of such wall panels is also easy, since they are easily stackable.
