Abstract

본 발명은 픽업 카트리지(Pick-Up Catridge)를 사용하는 음향 장치로써, 음반용 픽업 카트리지가 설치되고 음반을 회전시키는 턴테이블 본체와, 턴테이블 본체에 가해지는 진동 및/또는 충격으로 발생하는 진동 및/또는 충격음을 읽어 내는 진동 및/또는 충격음용 픽업 카트리지와, 진동음용 픽업 카트리지와 연결되어 진동음을 역위상으로 변환하는 역위상생성기와, 음반용 픽업 카트리지와 역위상생성기에서 출력되는 각 위상을 합성하는 위상합성기와, 위상합성기의 신호를 포노-앰프로 보내는 증폭회로부를 포함하여 이루어진다.The present invention relates to an acoustic device using a pick-up catridge, comprising: a turntable main body in which a pickup cartridge for a record is installed and rotating the record; and vibrations and / or generated by vibrations and / or shocks applied to the turntable main body; A pickup phase for synthesizing the vibration sound and / or the impact sound pickup cartridge, a reverse phase generator connected to the vibration sound pickup cartridge for converting the vibration sound into a reverse phase, and a phase for synthesizing each phase output from the record pickup cartridge and the reverse phase generator. And an amplifying circuit section for sending a signal of the phase synthesizer to the phono amplifier.
