Definitions

  • This invention is related to the enhancements carried out on the structures of the grilles which are in front of the speakers located on one side of the screen frame used on all kinds of audiovisual sound systems.
  • the speaker grilles are the components which take up the widest space in the screen frames of those devices.
  • Various grille designs are produced in order to protect the speakers from external influences and to provide the clearest sound possible.
  • the published patent applications EP1798967 , JP2008005459 , JP2007300281 , US2007223747 , and US7076078 can be listed as examples of those designs. As it can be inferred from those applications, the speakers and their grilles take up a significant space within the entire body of the televisions.
  • enhancements are provided for speaker grilles in the screen frames of audiovisual sound systems.
  • the sound provided by the speakers located behind the frames is ensured to pass out, facing the least number of barriers possible.
  • the reflected part of the sound provided by the speakers is directed towards the outer side of the frame by means of the physical modification applied.
  • the aim of this invention is to ensure the sound provided by the speakers behind the screen frames of the audiovisual sound systems to be less - affected by the barriers.
  • Another aim of this invention is to ensure the speaker grilles to occupy less space on the screen frames.
  • Another aim of this invention is to provide a speaker sound that is heard well, by means of modifications implemented on the design of the speaker grilles.
  • Yet another aim of this invention is to lessen the space taken up by the screen frames.
  • FIG. 1 A front view of an audiovisual sound system (A) is illustrated in Figure 1 .
  • the speaker grille (3) is located on the lower side of the frame (2) surrounding the screen (1) of the system (A).
  • the speaker grille (3) may also be located on the other sides of the frame.
  • FIG 2 a sectional view of an embodiment relating to a speaker grille (3p) already known in the art and location of it behind a screen frame (2).
  • a certain part of each speaker (4) faces an area where the sound reaches out through the grille (3p) without being blocked by any barrier (active area (10)) and the remaining part faces another area where the sound is reflected back after striking a barrier (inactive area (11)).
  • each speaker (4) is situated behind the screen frame (2) thus saving more place; however, the problem that the sound provided by the speaker (4) cannot be conveyed to the user in an effective way arises.
  • FIG 3 a sectional view of the speaker grille (3) of this invention and its location behind a screen frame (2) belonging to the system (A) is provided.
  • the speaker grille (3) here is also located in such a way that a certain part of it would be left behind the frame (2) or another barrier, and the other part would face an open area. Almost all or the most of the audio that is coming out of the speaker (4) behind the speaker grille (3) reach out through the openings (30) between the grille parts (31).
  • an audio output channel (33) (explained below) which is provided on the part of the speaker grille (3), left behind the frame (2).
  • the sound diverting surface (32) provided on the part of the speaker grille (3) that is behind the frame (2) in an inward-curving way to divert the audio output to the open side and with the audio output channel (33) provided through the grille part (31) next to that one, not only the frame (2) is prevented from blocking the audio output but also the speakers (4) and grilles (3) are located behind the frame (2) as much as possible.
  • Sound diverting surface (32) can be designed in different geometrical forms such as flat, concave and convex surfaces.
  • the sound diverting surface (32) may have a surface which is constructed with different combinations of at least two of the said flat, concave and convex surfaces.
