DEVICE FOR HIGH-END SOUND PLAYBACK Russian patent published in 1998 - IPC

FIELD: acoustic systems. SUBSTANCE: device has sound source and source pressure tuning unit which are located input housing with sound reflecting surface. Sound pressure tuning unit is designed as sound absorber which has system of liquid-saturated vapor with interface boundary generated on developed surface of heat accumulator. System of liquid-saturated vapor with interface boundary generated on developed surface of heat accumulator is sealed. Heat accumulator is designed as solid body which developed surface is moisturized with liquid of system or as just liquid of this system. System of liquid-saturated vapor with interface boundary generated on developed surface of heat accumulator may have additional gas in this volume. Sealing of this system is achieved by means of sound-transparent jacket, sound-transparent bellows and diaphragm as well as by means of housing and sound source in gas-tight design. Multiple-component solution may be used as liquid in system of liquid-saturated vapor. EFFECT: increased sound quality. 10 cl, 2 dwg
