본 고안은 휴대용 카세트의 음향 장치에 관한 것으로, 특히 저음부분에 충실도를 높일 수 있는 휴대용 카세트의 음향장치에 관한 것이다.The present invention relates to an acoustic apparatus of a portable cassette, and more particularly, to an acoustic apparatus of a portable cassette capable of increasing fidelity in the bass portion.
휴대용 카세트는 음향기기중에서도 가장 보편적으로 널리 이용되고 있는 것으로, 이러한 카세트는 일반적으로 좌, 우 스피커를 가지고 입체 음향 효과를 얻고 있다.Portable cassettes are the most widely used among audio equipment, and such cassettes generally have a stereo sound effect with left and right speakers.
그러나 이러한 카세트의 음향장치에서는 대체적으로 고음이 많이 발생하는, 즉 고음, 중음, 저음의 주파수 대역에서 저음부분의 음질이 고음부분의 음질에 비하여 극히 약화되어 고음대역측의 음이 주로 많이 감도되어 음향의 질이 낮아지게되는 문제점이 있었다.However, in the cassette sound system, high sound quality is generally generated, that is, the sound quality of the low end is extremely weak compared to the sound quality of the high end in the high, mid, and low frequency bands. There was a problem that the quality is lowered.
본 고안은 상기와 같은 사정을 고려하여 이루어진 것으로 그 목적은 음의 대역중 특히 저음역 부분의 음에 충실도를 높이여 부드럽고도 음질을 향상시키는 휴대용 카세트의 음향장치를 제공하는 것이다.The present invention has been made in view of the above circumstances, and an object thereof is to provide a sound cassette of a portable cassette which improves the fidelity and the sound quality by increasing the fidelity to the sound of the low range, especially in the low range.
본 고안의 다른 목적을 저렴한 가격으로 음질좋은 카세트를 제공함에 있다.Another object of the present invention is to provide a good sound quality cassette at a low price.
이러한 본 고안의 목적은 입체음향을 내는 즉 음량이나 위상차이를 재현시키게하는 좌측스피커와 우측스피커를 사용하도록된 휴대용 카세트를 제공함에 의해 달성되게 되는데, 이 카세트는 정, 후면체가 결합되어 구성되는 케이스와, 그 케이스의 전면 양측에 좌측스피커와 우측스피커가 설치되어 있다.The object of the present invention is achieved by providing a portable cassette that uses a left speaker and a right speaker that produce three-dimensional sound, that is, to reproduce the volume or phase difference, the cassette is a case consisting of a combination of the front and rear The left and right speakers are provided on both sides of the front surface of the case.
상기 좌, 우측 스피커의 사이에 후향으로 저음스피커가 구비되고, 이의 저음스피커에 공진실과 케이스 전면으로 개구되는 음출구를 가지는 음향통이 감싸지게 구성하고 있고, 따라서 저음 역대의 음대 충실도를 높히어 음질을 향상시키게 된다.Between the left and right speakers, a bass speaker is provided in a rearward direction, and the bass speaker is surrounded by an acoustic tube having a resonant chamber and a sound outlet opening to the front of the case, thereby increasing the fidelity of the bass band. It will improve the sound quality.
다음 본 고안의 실시예를 도면에 의거하여 구체적으로 설명하겠다.Next, embodiments of the present invention will be described in detail with reference to the drawings.
제 1 도에는 본 발명에 따른 휴대용 카세트가 도시되어 있는데 이 카세트는 한쌍의 전, 후면체(10A), (20B)가 결합되어 구성되는 케이스(10)와, 그 케이스(10)의 전면의 양측에 좌측스피커(11)와 우측 스피커(12)가 설치되어 있다.1 shows a portable cassette according to the present invention, which has a case 10 composed of a pair of front, rear bodies 10A, 20B, and both sides of the front surface of the case 10. The left speaker 11 and the right speaker 12 are provided at the side.
제 2 도 및 제 3 도에 음향장치가 상세하게 도시되어 있다.The acoustic device is shown in detail in FIGS. 2 and 3.
즉 케이스(10) 내의 좌, 우측스피커(11), (12) 사이에 저음스피커(20)을 후향으로 설치하고, 그 저음스피커(20)를 내측에서 음향통(30)으로 감싼다.That is, the bass speaker 20 is installed backward between the left and right speakers 11 and 12 in the case 10, and the bass speaker 20 is wrapped in the acoustic cylinder 30 from the inside.
이때 음향통(30)과 후면체(20B)의 접합부 사이에는 밀폐부재(40)가 개재되어 음향통내에서 공진되는 음이, 그 이외로 흘러나가지 않게하고 있다.At this time, the sealing member 40 is interposed between the joint of the acoustic cylinder 30 and the rear body 20B, and the sound which resonates in the acoustic cylinder does not flow out other than that.
음향통(30)은 그 몸체가 사각함체 형상으로 구성되어 그내부 일측, 즉 내부 중앙에서 일측으로 벗어난 위치에 분리벽(31)을 세우고 이 분리벽(31)을 중심으로하여 양측에 공진실(32)과, 음출실(33)을 구비하고 있다.Acoustic cylinder 30 has a body formed in a rectangular box shape, the separation wall 31 is erected at a position deviating from one side of the inner side, that is, the inner center to one side, and the resonance chamber ( 32 and the sound extraction chamber 33 are provided.
이때 분리벽(31)은 음향통(30)의 상면에서 약간 떨어지게 구비하여 공진실에서 공진되어 중폭된 저음이 음출실(33)로 넘어가게 구성하고 있다.At this time, the separating wall 31 is provided to be slightly away from the upper surface of the acoustic cylinder 30, and is configured so that the bass sound resonated in the resonant chamber and the heavy bass is passed to the sound output chamber 33.
또 상기 음출실(33)에는 케이스(10)의 전면에 구비된 개구부(101)측과 맞이어지는 음추구(331)를 연장설치하고 있다.In addition, the sound extraction chamber 33 is provided with a sound penetrating opening 331 which is aligned with the opening 101 provided on the front surface of the case 10.
그러면 제 2 도 및 제 3 도를 참조하여 음향 장치에 관해 상세하게 설명하겠다.Next, the acoustic device will be described in detail with reference to FIGS. 2 and 3.
저음스피커(20)에서 저음이 발생하면 이 저음은 음향통(30)의 공진실(32)에서 공진함과 동시 증폭되고 증폭된 저음은 분리벽(31)을 넘어 음출실(33)과 음출구 (331)를 통하여 카세트 전면에 구비된 개구부(101)를 거쳐 외부로 출력되어 저음이 음질에 충실도를 높히게 되는 효과가 있고, 이 저음은 양 좌우측 스피커에서 출력되는 고음과 합성되면서 부드럽고 고운 고질화된 음을 청취할 수 있게 되는 효과가 있다.When the bass is generated in the bass speaker 20, the bass is resonated in the resonant chamber 32 of the acoustic cylinder 30 and simultaneously amplified, and the amplified bass exceeds the partition wall 31 and the sound output chamber 33 and the sound outlet. 331 is output to the outside through the opening 101 provided on the front of the cassette has the effect of improving the fidelity to the sound quality, this bass is synthesized with the treble output from both left and right speakers while smooth and fine The effect is that you can listen to the sound.
