Description

The present invention aims to enhance the currents received from the telephone to obtain a loudspeaker.

The device of the present invention is illustrated in FIG. 1 and 2 schematic drawing.

The membrane of the phone is mechanically bonded with soft iron gland, which consists of two halves of Yat and Yaz and swings around the axis O. The two polarized electromagnet Al and Elg are opposite each other with the same poles and the ends of their cores are bent so that their geometric axes the ends pass through the axis O; On the curved ends of the electromagnet cores El and Elg are wound four coils TKi, TRa, TKz and TKi, which are included in the modulated current circuit. The inner surfaces of the pole tips of a single magnet, embracing the semicircular half of the core, go some distance beyond the edge of the half of the core so that the distance along the arc A is somewhat greater than the distance along the arc cd (Fig. 2).

A constant current from a battery of cells (Fig. 1) or from some current source passes sequentially through the windings of electromagnets and Els and creates a constant magnetic flux, closed through the pole tips of magnets, very small air gaps and iron halves of the core. Magnetic flux establishes measles strictly symmetrically with respect to the pole tips of permanent magnets (solid line and arrow in Fig. 2). As soon as an alternating current passes through the windings of the TKi, TKz, TKz and TKi coils, the measles will rotate in one direction or another, namely: in those coils in which the alternating current passes, in the same direction as the direct current, and the magnetic flux the magnet magnet strength will also increase, and in those where the alternating current is directed against a constant magnet, the magnet magnet strength will weaken. If in TC, the current will be in the opposite direction, the attraction of the core by this tip will be weaker, and in TC, the current will be of the same direction, and the attraction of the core will be enhanced; similarly, in TKz, the attraction will weaken, and in TK it will amplify. Under the influence of such a rotating pair of forces, the measles will rotate, in this case, clockwise, and take the position shown in FIG. 2 dotted line. With the reverse direction of the alternating current, the measles will turn in the opposite direction by the same amount. The device of inclined planes inside the core is intended to obtain the corresponding oscillations of the air environment and to obtain sound vibrations. The same effect is supposed to be achieved by lever transfer to the corresponding membrane.
