Description

In the proposed loudspeaker, in order to increase the effect of his actions, adjustable pole loudspeakers are used. Padstavki appropriate form, designed to reduce. magnetic scattering and creating the greatest density of magnetic flux passing through the bark placed on the neutral between pole extensions.

In the schematic drawing of FIG. 1 depicts the proposed loudspeaker with a partial section of the optars; FIG. 2 shows a section along the line AB in FIG. one.

In the specified loudspeaker (Fig. 1) between the ends of the permanent magnets f are clamped with bolts e pole extensions d, between which on the neutral line of the magnets there is a measur a attached to the middle of the steel plate c. The plate is fixed on columns 1 by bolts of the section. The anchor is connected with a membrane or a diffuser by means of a pin w, inclined to the plate c. The principle of action is no different from a regular phone. The alternating magnetic field of the coils d causes the measles to oscillate, the oscillations of which in turn are transmitted to the membrane or diffuser.

The loudspeaker is adjusted with the help of pole extensions d freely attached to the bolts. E. The adjustment limit is determined by the size of the gap between the pole extensions and the bolts.

Subject Patent a.

A loudspeaker characterized by the use of two permanent magnets f, each of which has the shape of a rectangular paralleled parallel and large axes of which are parallel, between the ends of what magnets the pole extensions d are clamped so as to concentrate the magnetic flux on the neutral line of the magnets f on which extensions d measles a, whose filler sh, going to the membrane or diffuser, is inclined to the plate carrying the measles, moreover to regulate the relative position of the core and the extensions of the extension c loosely attached to the mounting bolts.
