Definitions

  • the present invention relates to a loudspeaker arrangement in a device for the reproduction of stereophonic audio signals.
  • Loudspeaker arrangements for the reproduction of stereophonic audio signals which are integrated in a device, have become known.
  • the size specified by the device also determines the size of a housing used to accommodate the loudspeaker arrangement.
  • a loudspeaker arrangement in a device for the reproduction of stereophonic audio signals with a housing arranged in the device, a loudspeaker for low-frequency signals and loudspeakers for mid-range and high-frequency signals, with crossovers - in active or passive execution - for the stereophonic audio signals for the Separate reproductions with the speakers in low-frequency signals and mid and high-frequency signals, whose crossovers have a crossover frequency that is higher than the cut-off frequency of the loudspeaker for low-frequency signals.
  • the present invention has the advantage that a sound experience with a large volume of sound and sound can thereby be achieved, although the housing available for the loudspeaker arrangement has only a small spatial extent and a small volume.
  • FIG. 1 shows a three-dimensional representation of a loudspeaker arrangement in a device for the reproduction of stereophonic audio signals
  • Figure 2 shows a section through the device of Figure 1
  • FIG. 3 shows a basic circuit diagram of a control of the loudspeaker arrangement according to FIG. 1.
  • FIG. 1 shows a three-dimensional representation of a loudspeaker arrangement 10, 12, 13 in a device 20, 21, 22 for the reproduction of stereophonic audio signals.
  • the loudspeaker arrangement 10, 12, 13 comprises a loudspeaker 10 for the reproduction of low tones, for example a so-called sub-woofer, and a loudspeaker 12 for the reproduction of high and medium tones of a left stereo channel and a loudspeaker 13 for the reproduction of high and middle tones of a right stereo channel.
  • the device 20, 21, 22 has a foot 20, for the installation of the device, a fastening 21, for the fastening of further components of the device, such as electronic circuits, a display or panels, and a housing 22 for accommodating the loudspeaker arrangement 10, 12, 13 on. _ _
  • Contacts 15 are provided for the electrical connection of the loudspeaker arrangement 10, 12, 13.
  • FIG. 2 shows a section through the device 20, 21, 22 or through the housing 22 according to FIG. 1.
  • Each of the loudspeakers 10, 12, 13 has its own partial housing 27, 23, 24, the partial housing 23, 24 of the loudspeaker 12 for the left stereo channel and the speaker 13 for the right stereo channel, to avoid interference, are connected by means of chambers 25 and 26 to the partial housing 27 of the speaker 10 for low tones.
  • the partial housings 23, 24, 27 and / or the chambers 25 and 26 can be acoustically damped, for example, by means of suitable fiber material.
  • FIG. 3 shows a basic circuit diagram of a control 30 of the loudspeaker arrangement 10, 12, 13 according to FIG. 1.
  • a signal S for the left stereo channel is applied to a crossover 31.
  • the high and medium signal components of the signal SL reach an amplifier 35, which amplifies the signal components for playback with the loudspeaker 12 for the left stereo channel.
  • a signal S R for the right stereo channel is applied to a crossover 32.
  • the high and medium signal components of the signal S R reach an amplifier 36 which amplifies the signal components for playback with the loudspeaker 13 for the right stereo channel.
  • the low signal components of the signals S and S R are forwarded by the frequency branches 31 and 32 to a superimposition circuit 33, which generates a low-frequency signal therefrom, which is amplified by an amplifier 34 for playback with the loudspeaker 10.
  • Crossovers 31 and 32 can be formed in a known manner from capacitors and inductors.
  • a resistance network can be used to implement the superimposition circuit 33.
  • the crossover frequency of the crossovers is selected such that the Crossover frequency is higher than the cut-off frequency of the loudspeaker 10 for the reproduction of the low-frequency signal.
  • a suitable crossover frequency böi is about 350 Hz.
  • the distance between the loudspeakers 12 and 13 for the mid and high tone signal should be in the range of 150 - 500 mm.
  • the device comprising the loudspeaker arrangement can be a consumer electronics device, e.g. B. a CD player, a television, etc. But the device can also be a monitor for a computer or a computer. In these cases, the stereophonic audio signals to be reproduced come from the consumer electronics device or the computer.
