Description

.. - .L

The invention relates to a system of electricity .. a circuit consisting of an active and a potential electronic circuit, forming a fuscional unity, in which the transmission curves are radiated into space on the spot. Shani power. Rated :; uniform depending on the frequency

Sound emitters are known that contain high-and low-frequency radiotherapy units located in V-Norao space (e. Parts that have the electrical circuit. Consists of filters, level controls, and amplifiers power, connecting to the input node, and the high frequency radiation unit is made at least in the form of three simple or unified loudspeakers, the planes above the surface area, which are in pairs, deviating by 180, and the intersection lines of these planes are parallel to each other, where the sharpness perpendicular to this intersection of the cross, the rasgatta called the 0I space along the broken line; and the radiation axis of a multitude of such neighboring loudspeakers or sound speakers

of elements, alternating with each other in the perpendicular plane, once cut at the intersection points, forming a network of interference sites in front of and behind the border.

Such 1 samples do not provide for the preparation at the receiving site (sound equal to the intensity depending on the frequency.

The purpose of the invention. the output at the place of reception of sound, depending on the frequency of a more uniform power than could be obtained until now.

This is achieved by the fact that the block of high frequency NIN radiation is made on -. at least E to four loudspeakers and units: istepino1CH5 emitting a low frequency often: 1); W, the midpoint is horn from (the uppermost point is at a greater frequency, is located at a distance of 1.5 d 1megi) ; and the JKoi rival, which emits a low frequency, while the height and width of the korgg / sa are made with dimensions larger than {:. "; in the air the length of the wave corresponds to the O1 gay transmission frequency, and

I from frequency, has a practically constant schedule of directionality.
