본 고안은 초음파 차폐장치에 관한 것으로, 특히 발생된 컴비네이션 톤 성분중 인체에 유해한 초음파 성분은 급격히 감쇄시키고, 인체에 무해한 오디오 성분은 사람에게 그대로 전달될 수 있도록 한 초음파 차폐장치에 관한 것이다.The present invention relates to an ultrasonic shielding apparatus, and more particularly, to an ultrasonic shielding apparatus which rapidly attenuates ultrasonic components harmful to a human body among generated combination tone components, and allows audio components that are harmless to a human body to be transmitted to a human.
종래의 초음파 발생장치 및 초음파 스피커에서는 발생된 가청대역 이외의 초음파를 청취자 및 인접물에 직접 노출시키는 구조로 되어 있다. 따라서, 초음파에 노출된 인체에는 여러 가지 유해한 현상이 초래될 우려가 있으며, 인접한 결속물 및 접착물에도 손상을 끼칠 위험이 있었다.Conventional ultrasonic wave generators and ultrasonic speakers have a structure in which ultrasonic waves other than the audible band generated are directly exposed to a listener and an adjacent object. Therefore, there is a risk that a number of harmful phenomena may occur in the human body exposed to the ultrasonic waves, there was a risk of damaging the adjacent bonds and adhesives.
이하, 첨부도면을 참조하여 종래의 초음파 발생장치에 대해 살펴보기로 한다.Hereinafter, a conventional ultrasonic wave generator will be described with reference to the accompanying drawings.
도 1은 종래기술에 따른 초음파 발생장치의 구성도로서, 매칭회로(1), 후면층(2), 초음파 진동자(3), 전면층(4)(5) 등으로 구성되어 있다.1 is a configuration diagram of an ultrasonic generator according to the prior art, and is composed of a matching circuit 1, a back layer 2, an ultrasonic vibrator 3, a front layer 4, 5, and the like.
도 1에 도시된 바와 같이, 종래의 초음파 스피커는 두 개의 각각 다른 주파수의 초음파를 합성시키는 컴비네이션 톤(Combination Tone)을 이용하여 오디오 신호를 재생하는 방법을 사용하고 있다. 이러한 컴비네이션 톤에는 가청주파수 대역의 오디오 신호 이외에 인체에 유해한 또다른 초음파 성분이 포함되어있다.As shown in FIG. 1, a conventional ultrasonic speaker uses a method of reproducing an audio signal using a combination tone combining two different frequencies of ultrasonic waves. In addition to audio signals in the audio frequency band, these combination tones contain other ultrasonic components that are harmful to the human body.
이와 같이 구성된 종래의 초음파 스피커에 있어서는, 발생된 컴비네이션 톤(Combination Tone) 성분중 초음파 성분의 밀집된 에너지가 인접물에 직접적으로 전달되어 인체 및 사물에 해를 끼칠 위험성이 있었다.In the conventional ultrasonic speaker configured as described above, the dense energy of the ultrasonic component among the generated combination tone components is directly transmitted to the neighbors, which may injure the human body and the object.
따라서, 본 고안은 상기 문제점을 해결하기 위하여 안출된 것으로써, 본 고안의 목적은 발생된 컴비네이션 톤 성분중 인체에 유해한 초음파 성분은 급격히 감쇄시키고, 인체에 무해한 오디오 성분은 사람에게 그대로 전달될 수 있도록 한 초음파 차폐장치에 관한 것이다.Therefore, the present invention has been devised to solve the above problems, the object of the present invention is to rapidly attenuate the ultrasonic components harmful to the human body of the generated combination tone components, so that the audio components that are harmless to the human body can be delivered to humans as they are. It relates to an ultrasonic shield.

상기 목적을 달성하기 위하여, 본 고안의 초음파 차폐장치는 적어도 1개 이상의 초음파 발생장치의 전방에 위치하며 감쇄계수가 공기보다 큰 매질의 차폐층을 이용하여 고주파 성분은 상쇄시키고, 저주파 성분은 그대로 전달시키도록 하는 것을 특징으로 한다.In order to achieve the above object, the ultrasonic shielding device of the present invention is located in front of at least one or more ultrasonic wave generating device and the high frequency component is canceled by using a shielding layer of a medium having attenuation coefficient larger than air, and the low frequency component is transmitted as it is. It characterized in that to make.
이하, 본 고안의 일실시예에 관하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 2 는 본 고안의 제1 실시예에 의한 초음파 차폐장치가 부착된 초음파 발생장치의 구성도로서, 매칭회로(1), 후면층(2), 초음파진동자(3) 및 전면층(4)(5)으로 구성된 초음파 발생장치로부터 발생한 초음파를 컴비네이션 톤을 형성한 후 차폐층을 통해 감쇄되도록 상기 초음파 발생장치의 전면에 차폐층(6)을 구비하였다.2 is a configuration diagram of an ultrasonic wave generator with an ultrasonic shielding device according to a first embodiment of the present invention, which includes a matching circuit 1, a rear layer 2, an ultrasonic vibrator 3 and a front layer 4 ( A shielding layer 6 was provided on the front surface of the ultrasonic wave generating device to attenuate the ultrasonic wave generated from the ultrasonic wave generating device 5) by forming a combination tone and then through the shielding layer.
본 고안에서는 음파의 매질내에서의 감쇄가 그 주파수 및 매질의 감쇄계수에 비례하는 원리를 이용하여 컴비네이션 톤(Combination Tone)에 의해 발생된 고주파 성분은 공기만으로는 충분한 감쇄가 일어나지 않으므로, 감쇄계수가 공기보다 큰 매질을 차폐층(6)으로 사용한 차폐장치를 이용하여 고주파 성분을 상쇄시켜서 인체에 해가 없도록 하고, 저주파 성분인 오디오 신호만을 전달시키도록 하였다.In the present invention, the attenuation coefficients in the medium of the sound wave are proportional to the frequency and the attenuation coefficient of the medium. A shielding device using a larger medium as the shielding layer 6 was used to cancel high frequency components so as not to harm the human body, and to transmit only an audio signal having a low frequency component.
도 3은 본 고안의 제2 실시예에 의한 초음파 차폐장치가 부착된 초음파 발생장치의 구성도이다.3 is a block diagram of an ultrasonic generator with an ultrasonic shielding apparatus according to a second embodiment of the present invention.
도 3에서와 같이, 본 고안은 초음파를 발생시키기 위해 구성된 2개이상의 진동자의 배열(array)에 적용하여, 두 초음파의 상호작용 결과 발생되는 각기 다른 주파수 성분을 선택적으로 여과시키도록 하였다.As shown in FIG. 3, the present invention is applied to an array of two or more vibrators configured to generate ultrasonic waves, thereby selectively filtering different frequency components generated as a result of the interaction of two ultrasonic waves.
또한, 본 고안에 의하면, 차폐장치를 구성하기 위하여 각종 커버(cover) 및 그릴결합물(grille assembly), 저지(Jersey), 음향렌즈 등 전면 외관용 및 보호용 부품과 결합된 상태로 사용할 수 있다.In addition, according to the present invention, in order to configure the shielding device, it can be used in combination with various cover and grill assembly, jersey, front exterior and protective parts such as acoustic lenses.
앞에서 설명한 바와 같이, 본 고안의 초음파 차폐장치는 인체에 전달되는 초음파를 차폐층(6)을 통해 급격히 감쇄시킴으로써 청취자 및 주변물에 해가 없도록 하여 안정성을 확보하는 효과를 거둘 수 있다.As described above, the ultrasonic shielding device of the present invention can achieve the effect of ensuring stability by harming the listener and the surroundings by rapidly attenuating the ultrasonic wave transmitted to the human body through the shielding layer (6).
