Изобретение относитс к области акустической техники и может найти применение на транспортных устройствах.The invention relates to the field of acoustic technology and can be used on transport devices.
В известных электрических звонках посто нного тока звук создаетс посредством двух звучащих пластин, соединенных между собою в центре, где они прикреплены к корю электромагнита .In the known direct current electric bells, sound is created by means of two sounding plates connected to each other in the center, where they are attached to the electromagnet core.
Предлагаемое устройство отличаетс от известных тем, что звучащие пластины не соединены между собою и прикреплены к разным кор м одного соленоидного электромагнита, что расшир ет полосу воспроизводимых звуковых частот.The proposed device differs from the known ones in that sounding plates are not connected to each other and are attached to different cores of one solenoid electromagnet, which expands the range of reproducible sound frequencies.
На чертеже показан описываемый звонок посто нного тока, состо щий из корпуса 1, электромагнита 2 с двум кор ми 3 и двух звучащих пластин 4 и 5.The drawing shows the described DC bell consisting of body 1, electromagnet 2 with two cores 3 and two sounding plates 4 and 5.
При работе данного устройства посто нный ток через прерыватель, здесь не показанный, поступает в обмотку электромагнита, что вызывает прит жение обоих корей и прикрепленных к ним звучащих пластин. Во врем разрыва цепи тока прерывателем оба кор и пластины возвращаютс в исходное положение . Затем процесс повтор етс . Независимые колебани двух пластин создают щирокую полосу звуковых частот.When this device operates, a direct current through the interrupter, not shown here, enters the electromagnet winding, which causes attraction of both koreas and sounding plates attached to them. During the break of the current circuit by the chopper, both the core and the plates return to their original position. The process then repeats. The independent vibrations of the two plates create a wide band of sound frequencies.
