Abstract

본 발명은 스피커에서 발생되는 음파에 의한 중저음 및 울림을 감소시켜 음의 명료도를 향상시키는 동시에 전자관이 화면떨림현상을 감소시키도록 한 모니터의 스피커음압감소장치에 관한 것으로, 전자관(10)이 조립된 프론트커버(20)의 후방에 일체로 조립되어 전방 양측면에 각각 다수의 음파구멍(31)이 형성되는 백커버(30)와, 백커버(30)내의 샤시프레임(70)에 일체로 조립되도록 전방에 스피커(40)가 설치된 캡(50)과, 캡(50)의 전방 일측에 조립되어 스피커(40)의 음파를 백커버(30)의 음파구멍(31)으로 안내하여 음압과 진동이 감소되도록 다수의 음파안내구멍(61)이 형성된 음파가이드(60)로 구성하며, 스피커(40)에서 발생되는 음파는 스피커(40)의 경사각도에 의하여 음파가이드(60)축으로 진행하게 되며, 음파가이드(60)로 진행된 음파는 음파가이드(60)에 형성된 다수의 음파안내구멍(61)을 통과하게 되고, 음파안내구멍(61)을 통과한 음파는 백커버(30)의 음파구멍(31)을 통해 외부로 빠져나가도록 한다.The present invention relates to a speaker sound pressure reduction device for a monitor that reduces the bass and ringing caused by sound waves generated by a speaker to improve sound intelligibility and reduces an image vibration phenomenon at the same time the electron tube 10 is assembled. The front cover 20 is integrally assembled at the rear of the front cover 20 so that a plurality of sound wave holes 31 are formed at both front and rear sides thereof, and the front is integrally assembled to the chassis frame 70 in the back cover 30. Cap 50 is installed in the speaker 40, and the front side of the cap 50 is assembled to guide the sound waves of the speaker 40 to the sound wave hole 31 of the back cover 30 so that the sound pressure and vibration is reduced It consists of a sound wave guide 60 formed with a plurality of sound wave guide holes 61, the sound wave generated from the speaker 40 proceeds to the sound wave guide 60 axis by the inclination angle of the speaker 40, the sound wave guide Sound wave proceeded to 60 is formed in the sound wave guide (60) Passed through the plurality of sound wave guide holes 61, the sound wave passed through the sound wave guide hole 61 is to pass through the sound wave hole 31 of the back cover 30 to the outside.
