Definitions

  • the invention is concerned with the design of subwoofer loudspeakers, in particular with the simplification of the manufacturability of such boxes.
  • the speaker can be formed by the fact that equipped with the speaker, etc. partition is inserted into the drawer frame by a housing housing also available in the mounting hole. Since the partition wall is provided with a cover plate, when the cover plate is larger than the mounting hole, the mounting hole is closed with the reaching of the end position of the partition in the drawer frame.
  • cover plate seals the mounting opening only partially, i. not completely off, then the remaining opening can be used as a port. This eliminates the need for separate ports in the box body.
  • this cover wall can be used for heat dissipation.
  • the partition is additionally equipped with an amplifier unit.
  • cover plate is provided with a contact strip for contacting the loudspeaker or the amplifier unit, no further mounting opening in the box housing is necessary any more, as a result of which the sealing effort is reduced.
  • FIG. 1 shows a box housing (10) which is substantially closed in a somewhat cuboidal shape, wherein the outer skin (11) of this housing (10) is only interrupted by a mounting opening (12) and a channel-shaped port (13). Furthermore, the interior of the box housing (10) of 4 tubular passages (14), which contribute to the mechanical stability of the box housing (10).
  • a slide-in frame (16) is formed on the inner wall (15) of the housing, which, as the left side of the illustration in FIG. 1 shows, has an approximately U-shaped profile.
  • the right side in the illustration Figure 1 is removable, that the insertion frame (16) ends where the outer skin (11) of the housing (10) has the mounting opening (12). The latter is essential - as will be shown later - to complete the speaker.
  • FIG. 2 which shows a section AA according to FIG. 1, can be seen that the insertion frame (16) runs along the two side surfaces 17.1 and 17.2 as well as on the end face (18) of the inner wall (16).
  • box housing (10) shown in FIGS. 1 and 2 can be made very easily from plastic by using rotational sintering or application of the blowing technique.
  • FIG. 3 shows an acoustic module (19).
  • This acoustic module (19) is essentially formed by a partition wall (20), a cover plate (21) connected to the partition wall (20), a loudspeaker (23) and an amplifier unit (24).
  • the partition (20) has an opening (22) is formed, over which the speaker (23) is mounted.
  • the heat sinks (25) of the amplifier unit (24) are connected to the cover plate (21) and (20), which is formed in the present embodiment for better heat conduction from metal.
  • the cover plate (21) may also be formed of plastic and possibly a single-unit with the partition (20 ) form.
  • the cover plate (21) with terminal block (26) for contacting the amplifier unit (24) is provided.
  • FIG. 3 If now a completely populated acoustic module (19) according to FIG. 3 with the peripheral edge (27) of the dividing wall (20) is pushed through the mounting opening (12) FIG. 1 into the slide-in frame (16), an installation situation is achieved which is shown in FIG is. If the acoustic module (19) has assumed its end position in the box housing (10), the cover plate (21) closes the mounting opening (12). In addition, in this end position, the interior of the box housing (10), because the peripheral edge (27) of the partition (20) is mounted in the drawer frame (16), divided into a closed volume (28.1) and an open volume (28.2).
  • peripheral edge (27) of the partition (20) is provided with a seal (29) to ensure the mutual sealing of the two volumes (28.1) and (28.2). Also, a seal (29) is provided between the cover plate (21) and the outer skin (11) of the box body (10).
  • FIG. 5 shows a slightly modified embodiment in comparison to FIG. According to Figure 5, the port (13) is not guided by the outer skin (11) of the box body itself, but in the cover plate (21) is formed. Again, the port (13) is tubular.
  • the port opening required in each case can also be realized by means of a bore in the cover plate (21) or by the cover plate (21) not completely completing the mounting opening (12) in the box housing (10) covered.
