Definitions

  • the invention relates to a device for the reproduction of acoustic stereo signals with at least two speakers.
  • the invention is therefore based on the object of providing a device for reproducing acoustic stereo signals which is of compact construction and nevertheless enables a sufficient distance between the loudspeakers.
  • the advantage achieved by the invention is, in particular, that the device can be designed as a portable radio receiving device that can be accommodated in the smallest space and still allows the reproduction of stereo signals.
  • the 1 shows a device 1 for the reproduction of acoustic signals, which consists of two parts, namely a lower part 2 and an upper part 3.
  • the lower part 2 contains a loudspeaker 4 at its left end and in its central region a radio receiving part 5 and a cassette device 6.
  • a handle 7 for carrying the device 1 is arranged at the upper end of the lower part 2.
  • At the lower end of the lower part 2 there is a base plate 8 which has the shape of a Traoezes.
  • the loudspeaker 4 is arranged at an angle of 45 ° relative to the front surface of the radio receiving part 5 and also relative to the base surface provided parallel thereto.
  • the upper part 3 is displaceable parallel to the front surface of the radio receiving part 5, specifically via corresponding slide rails 10 or the like.
  • This upper part 3 has the shape of a cuboid, the two side parts of which are chamfered at an angle of 45 °. In one side part there is a recessed grip 11, while the other side part is formed by a loudspeaker 12. Antennas 13 are also provided on the upper side of the lower part 2.
  • FIG. 2 shows the same device as FIG. 1, but in a pushed-together state.
  • the distance between the loudspeakers 4 and 12 is therefore reduced here, so that the device 1 can be carried comfortably.
  • FIG. 3 shows the same device as in FIG. 1, in a partially pushed-together state, whereby the loudspeaker 4, the base plate 8, the recessed grip 11 and the radio receiver part 5 can be seen.
  • FIG. 6 shows a top view of the device 1, in which the handle 7 can be seen and the lower and the upper part 2 and 3 respectively.
  • the edges 20 to 28 are designated, which can be provided with foam ( see P 27 38 323.9).
