Description
II
Изобретение относитс к приборо- . : строению и может быть использовано в электропроигрывающих устройствах.The invention relates to an instrument. : the structure and can be used in electric devices.
Известно устройство, в котором демпфирование звукоснимател осуществл етс механическим способом: грубое - посредством противовеса, подвижно установленного на одном. из концов тонарма, при этом на другом конце тонарма закреплена головка звукоснимател . Кроме того, звукосниматель содержит пружину, нат нутую между точкой на плече звукосни мател и точкой на шасси проигрывател , причем последн соединена , с пружиной.гибкой св зью, например шнуром, перекинутым через ролик, наход щийс на горизонтальной оси вращени . Путем изменени нат жени пружины за счет перемещени точки закреплени конца пружины на шасси производитс точное демпфирование l .A device is known in which the pickup is damped mechanically: coarse - by means of a counterweight movably mounted on one. from the ends of the tonearm, while at the other end of the tonear the head of the pickup is fixed. In addition, the pickup contains a spring tensioned between a point on the pickup arm and a point on the chassis of the player, the latter being connected to a spring by a flexible link, for example, a cord thrown over a roller on the horizontal axis of rotation. By varying the tension of the spring by moving the point of attachment of the end of the spring to the chassis, precise l damping is performed.
Недостатком известного устройства вл етс мала точность демпфировани .A disadvantage of the known device is the low damping accuracy.
Наиболее близким по технической сущности к предлагаемому вл етс устройство дл воспроизведени звука с грампластинки, содержащее основание, тонарм, установленный подвижно на стойке, с расположенными на разных его концах головкой с иглой и противовесом, а также сервопривод , преобразователь которого подключен к исполнительному элементу, установленному с возможностью воздействи на тонарм 23.The closest in technical essence to the present invention is a device for reproducing sound from a gramophone record, containing a base, a tonearm movably mounted on a stand, with a head with a needle and a counterweight located at different ends, and a servo drive, the converter of which is connected to the actuator mounted with the possibility of impact on the arm 23.
