ä, i tweeter box for

_ Stereo speaker layout

The innovation concerns a tweeter box for a stereo loudspeaker arrangement in which tweeters and woofers are assigned to each transmission channel are.

The woofers emit the lower frequencies up to approx. 300 Hz and the tweeters emit the middle and higher frequencies above approx. 3 Hz.

The tweeters used hitherto in known stereo loudspeaker arrangements concentrate the sound radiation with increasing frequency, so that with normal stereophonic installation at the listening position the high frequencies are disadvantaged and the sound power in the room decreases with increasing frequency. Also missing from such an arrangement the secondary sound event, i. the perceptibility of the middle and higher of the Walls and the like reflected sounds.

The innovation is based on the task of a tweeter box of the type described in more detail at the beginning Type to eliminate the aforementioned disadvantages and the "stereo listening zone", especially with acoustics poorly cut rooms to expand.

In the case of a tweeter box of the type specified in the introduction, this object is achieved by that according to the innovation, the tweeter box is designed as a spherical radiator.

The innovation is described below with reference to the figure. This only shows the essential parts the new tweeter box of a stereo loudspeaker arrangement namely in the middle a woofer box containing one or more woofers 1, which is designed for the emission of low frequencies up to approx. ^ Too Hz, and to the side of it two tweeter boxes 2 in the form of spherical emitters, which are used for the radiation of the Frequencies above about 400 Hz are formed. A spherical radiator can, especially the higher frequencies, radiate all around, i.e. on all sides. Each of these tweeter boxes 2 has six

in hexahedron form, preferably on a common base 5 arranged individual speakers h .

Based on the fact that the frequencies below a certain frequency (approx. 3oo Hz) are no longer are to be located and around the spherical emitters to be as small as possible hold, the transmission frequency band was divided into a bass range (up to about 'loo Hz), whose frequencies of both channels the woofer or speakers 3 housed in the middle housing and its middle and higher frequencies are supplied to the respectively assigned tweeter box 2, which is designed as a spherical radiator will.
