본 고안은 자동차용 스피커에 관한 것으로서, 보다 구체적으로는 자동차의 도어 내부에 장착되며 물막이 덮개가 부착된 스피커에서 발생되는 음질의 왜곡현상을 개선할 수 있는 자동차용 스피커에 관한 것이다.The present invention relates to a car speaker, and more particularly, to a car speaker that is mounted inside the door of the car and can improve the distortion of sound quality generated in the speaker with a water cover.
제1도는 일반적인 자동차용 스피커의 뒷면 구성을 나타낸 절개 평면도이고, 제2도는 제1도에 나타낸 스피커의 장착 및 작동 상태를 발췌 도시한 측면도이다.FIG. 1 is a cutaway plan view showing a rear structure of a general automotive speaker, and FIG. 2 is a side view showing the mounting and operating states of the speaker shown in FIG.
제1도에서, 일반적인 자동차용 스피커(10)의 뒷면은, 외면에 열 또는 음파를 발산할 수 있도록 복수개의 통기공(2a)이 관통 형성된 콘 형의 프레임(2)과, 상기 프레임(2)의 외주연에 차체와 고정되도록 절곡형성된 체결부(2b)와, 상기 체결부(2b)의 절곡면을 따라 프레임(2)을 일정범위만 커버하여 빗물 등을 막을 수 있도록 부착 설치되는 물막이덮개(4)로 구성된다.In FIG. 1, a rear surface of a general automotive speaker 10 includes a cone-shaped frame 2 having a plurality of vent holes 2a formed therein so as to radiate heat or sound waves to an outer surface thereof, and the frame 2. Fastening part (2b) bent to be fixed to the vehicle body and the outer periphery of the water cover, which is attached to cover the frame 2 only a certain range along the bending surface of the fastening part (2b) to prevent rain water, etc. 4) consists of.
이와같이 구성된 종래의 스피커(10)는 제2도에 도시된 바와 같이, 자동차 도어내부(s1)에 내장되어 프레임(2)의 체결부(2b)에 의해 고정된다.As shown in FIG. 2, the conventional speaker 10 configured as described above is embedded in the vehicle door inner s 1 and fixed by the fastening part 2b of the frame 2.
도면중 화살표는 음파의 전달 방향을 나타낸 것으로서, 스피커(10)에 전기적 신호가 입력되어 음파가 발생되면 상기 스피커(10)의 전방측인 자동차 실내(s2)에 대부분의 음파가 전달되고, 그 후방측인 자동차 도어내부(s1)에도 프레임(2)의 통기공(2a)을 통하여 음파가 전달된다.Arrows in the drawing indicate the direction of the sound wave, when the electrical signal is input to the speaker 10, when sound waves are generated, most of the sound waves are delivered to the vehicle interior (s 2 ) that is the front side of the speaker 10, Sound waves are also transmitted through the vent hole 2a of the frame 2 to the inside of the automobile door s 1 on the rear side.
특히, 상기 자동차 도어내부(s1)로 전달되는 음파는 물막이 덮개(4)의 내측면에 부딪혀 반사되기도 하고, 개방된 프레임(2) 외부로 발산되는 음파는 상기 도어 내부(s1)로 확산된다.In particular, the sound waves transmitted to the inside of the automobile door s 1 may be reflected by hitting the inner surface of the water cover 4, and the sound waves emitted outside the open frame 2 may diffuse into the inside of the door s 1 . do.
그러나, 물막이덮개(4)의 내면에 부딪혀 반사되는 음파와 스피커(10)전면의 진동판(도시안됨)으로부터 계속해서 발산되는 음파가 상호 충돌하여 자동차 도어 내부(s1)에 상기 물막이 덮개(4) 자체의 공진이상음과 더불어 기타 잡음이 유발되어 스피커의 음질을 왜곡시키는 문제점이 있었다.However, the sound wave hit by the inner surface of the clapper cover 4 and the sound wave continuously emitted from the diaphragm (not shown) on the front surface of the speaker 10 collide with each other, so that the clapper cover 4 is in the interior of the automobile door s 1 . In addition to the resonance noise of its own, other noise was caused to distort the sound quality of the speaker.
또한, 프레임(2)과 물막이덮개(4)의 접합부에서도 떨림음이 발생되어 자동차실내(s2)로 불필요한 잡음이 전달되는 다른 문제점도 있었다.In addition, there was also another problem that tremors are also generated at the junction of the frame 2 and the clapper cover 4 so that unnecessary noise is transmitted to the vehicle interior s 2 .
따라서 본 고안은 상술한 문제점을 해소하기 위하여 창안된 것으로서, 본 고안의 목적은 물막이 덮개 내부에 흡음재를 부착 설치하여 자동차 도어내에서 발생되던 잡음을 제거시킬 수 있는 자동차용 스피커를 제공하는데 있다.Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to provide a speaker for an automobile that can remove noise generated in an automobile door by attaching a sound absorbing material inside a water cover.
상기의 목적을 달성하기 위하여 본 고안에 의한 자동차용 스피커는, 자동차 도어 내부에 내장되는 콘형의 프레임과, 상기 프레임의 외주연에 후방으로 일정범위만 감쌀 수 있도록 부착 설치되는 물막이 덮개를 구비하되, 상기 물막이 덮개의 내면에 흡음재가 부착설치된 것을 특징으로 한다.In order to achieve the above object, the automobile speaker according to the present invention includes a cone-shaped frame embedded in an inside of a car door, and a water barrier cover attached to be installed to cover only a predetermined range to the outer periphery of the frame, The sound absorbing material is installed on the inner surface of the water cover.
이하, 본 고안의 바람직한 일실시예를 첨부된 도면에 의하여 상세히 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail by the accompanying drawings.
제3도는 본 고안에 의한 자동차용 스피커의 장착 및 작동상태를 발췌 도시한 측면도이다.Figure 3 is a side view showing an excerpt of the mounting and operation of the vehicle speaker according to the present invention.
제3도에 의하면, 본 고안의 스피커(100)는 자동차 도어 내부(s1)에 콘형의 프레임(20)이 내장되고, 상기 프레임(20)의 외면에는 열 또는 음파를 발산할 수 있도록 복수개의 통기공(22)이 관통형성된다. 그리고 상기 프레임(20)의 외주연에는 차체와 결합고정될 수 있도록 체결부(24)가 절곡 형성된다.According to FIG. 3, the speaker 100 of the present invention has a cone-shaped frame 20 embedded in an interior s 1 of a car door, and a plurality of speakers may emit heat or sound waves on an outer surface of the frame 20. Vent 22 is formed through. And the outer periphery of the frame 20, the fastening portion 24 is formed to be bent and fixed to the vehicle body.
상기 프레임(20)의 체결부(24)의 절곡면을 따라 물막이 덮개(40)가 상기 프레임(20)을 일정범위만 커버할 수 있도록 부착 설치되고, 상기 물막이 덮개(40)의 내면에는 도포나 도장이 가능한 도료 및 댐핑제를 칠한후 발포성 흡음재(60)가 부착 설치된다.Abutment cover 40 is installed along the bent surface of the fastening portion 24 of the frame 20 so as to cover the frame 20 only a predetermined range, the coating or coating on the inner surface of the water cover 40 After coating the paint and the damping agent capable of painting, the foamable sound absorbing material 60 is attached.
특히, 제4도에 확대 도시된 바와같이, 상기 흡음재(60)는 프레임(20)과 물막이 덮개(40)와의 접합부(42)에도 부착 설치된다.In particular, as shown in an enlarged view in FIG. 4, the sound absorbing material 60 is also attached to the joint portion 42 between the frame 20 and the water cover 40.
상기와 같이 구성된 본 고안에 의한 스피커(100)는, 전기적 신호가 입력되어 도시안된 진동판이 음파를 발생하면 자동차의 실내(s2)로 대부분의 음파가 전달되고, 또한 프레임(20)의 통기공(22)을 통해 자동차 도어 내부(s1)에도 음파가 전달된다.In the speaker 100 according to the present invention configured as described above, when an electrical signal is input and a diaphragm (not shown ) generates sound waves, most sound waves are transmitted to the interior of the vehicle s 2 , and the air vents of the frame 20 are also provided. Sound waves are also transmitted to the inside of the vehicle door s 1 through 22.
이때, 상기 자동차 도어 내부(s1)로 전달되던 음파의 일부는 물막이 덮개(40) 내면에 부착된 흡음재(60)에 흡수 소멸되어 물막이 덮개가 없는 상태와 같이 상기 도어(s1) 내부로 발산되는 역할을 하므로 스피커(100)의 진동판의 동작을 방해하지 않게 되어 충돌잡음이나 물막이 덮개(40) 자체의 공진 이상음의 발생이 저지될 수 있다.At this time, a portion of the sound wave transmitted to the inside of the car door (s 1 ) is absorbed and extinguished by the sound absorbing material 60 attached to the inner cover 40, the diverging into the inside of the door (s 1 ), such as a state without the cover. Since it does not interfere with the operation of the diaphragm of the speaker 100, the collision noise or the occurrence of the resonance abnormal sound of the cover 40 itself can be prevented.
한편, 상기 프레임(20)과 물막이 덮개(40)의 접합부(42)에도 흡음재(60)가 부착되므로 종래에 발생되던 떨림음도 감소시킬 수 있어 더욱 바람직하다.On the other hand, since the sound absorbing material 60 is also attached to the joint portion 42 of the frame 20 and the water cover 40, it is more preferable to reduce the vibration that is conventionally generated.
따라서, 상술한 바와같이 본 고안에 의한 자동차용 스피커는 자동차 내부에서 발생되던 음질의 왜곡현상을 감쇄시켜 스피커 진동판의 구동을 원활히 할 수 있으므로 결국 자동차 실내로 전달되는 음파의 질을 보다 향상시킬 수 있는 효과가 있어 이를 채용한 자동차의 신뢰성을 높일 수 있는 유용한 고안이다.Therefore, as described above, the automobile speaker according to the present invention can smoothly drive the speaker diaphragm by attenuating the distortion of sound quality generated inside the vehicle, thereby improving the quality of sound waves that are eventually delivered to the vehicle interior. It is effective and it is a useful design that can increase the reliability of the car employing it.
