Abstract

Изобретение относитс  к механической звукозаписи и позвол ет улучшить качество звуковоспроизведени  и долговечность грампластинок за счет их увлажнени  посредством охлаждени  до температуры ниже точки росы.The invention relates to mechanical sound recording and allows improving the quality of sound reproduction and durability of records due to their moistening by cooling to a temperature below the dew point.

Description

Изобретение относитс  к механической звукозаписи и может использоватьс  при воспроизведении гармзаписи с грампластинок .This invention relates to mechanical sound recordings and can be used when playing back recordings from phonograph records.

Цель изобретени  -улучшение качества звуковоспроизведени  и долговечности грампластинок.The purpose of the invention is to improve the quality of sound reproduction and durability of records.

Claims (1)

Ублажение грампластинок производитс  их охлаждением во врем  воспроизведени  до температуры ниже точки росы с помощью, например, съемного герметичного контейнера, заполненного хладагентом и предварительно охлажденного. Например, при температуре воздуха во врем  звуковоспроизведени  20°С и относительной влажности 70% температура точки росы составл ет 1б° С. В результате на поверхности грампластинки при ее охлаждении до температуры -10°С конденсируетс  равномерный слой атмосферной влаги. При этом возрастает твердость материала грампластинки, возрастает ее изно- состойкость и повышаетс  качество звуковоспроизведени  за счет повышени  резонансной частоты пары игла - канавка. Кроме того, атмосферна  влага на грампластинке не состал ет никаких следов. Формула изобретени  Способ воспроизведени  грамзаписи, при котором производ т увлажение поверхности контакта грампластинки с иглой звукоснимател , отличающийс  тем, что. с целью улучшени  качества звуковоспроизведени  с повышением долговечности грампластинки , увлажнение грймпластинки в процессе звуковоспроизведени  производ т с помощью ее охлаждени  до температуры ниже точки росы.The smoothing of the records is made by cooling them during playback to a temperature below the dew point using, for example, a removable sealed container filled with refrigerant and pre-cooled. For example, when the air temperature during sound reproduction is 20 ° C and the relative humidity is 70%, the dew point temperature is 1 ° C. As a result, a uniform layer of atmospheric moisture condenses on the surface of the record when it is cooled to a temperature of -10 ° C. At the same time, the hardness of the record material increases, its wear resistance increases, and the quality of sound reproduction increases due to an increase in the resonant frequency of the needle – groove pair. In addition, atmospheric moisture on shellac does not constitute any trace. Claims of the method of reproducing a record in which the contact surface of the record is removed from the pickup needle, characterized in that. In order to improve the quality of sound reproduction with increasing longevity of the record, humidification of the plate during sound reproduction is performed by cooling it to a temperature below the dew point.
