Abstract

본 발명은 박형(THIN TYPE)고출력 스피커 유닛에 관한 것으로서, 종래의 스피커는 그 부피가 크고, 지그지그의 음통로 구성이나 트럼펫형의 혼 구조에 따라, 소형 경량화하기 어려우며, 실내 설치등에는 부적합한 문제점과, 출력 소형 스피커로 제공되고 있는 피에조 소자를 진동자로 활용한 스피커의 경우, 피에조 소자는 그 주파수 특성상 고음역에 한정될수 밖에 없고, 음색이 떨어지기 때문에 특정 주파수의 경보음(사이렌 음)만을 재생 및 복사할 수 있으며, 음성 신호의 확성에는 적합하지 못하여 사용 불가능한 문제점이 있다. 본 발명은 드라이버 유닛과 하우징으로 구성되고, 상기 드라이버 유닛에서 출력된 오디오 신호가 고압으로 압축되는 압축실과, 상기 압축실과 연결되며 압축실에서 압축된 오디오 신호를 복사시켜 주기위한 음향 복사 노즐과, 상기 음향 복사 노즐과 연결되며 음향 복사 노즐에서 복사된 오디오 신호를 공명시켜 증폭하고, 또한 이 증폭된 오디오 선호의 음전달 경로를 전환시켜 주는 음향 공명 및 반사 나팔과, 상기 음향 공명 및 반사 나팔과 연결되며 음향 공명 및 반사 나팔에서 증폭되고 반전된 오디오 신호를 공간으로 최종 유도 및 확성해 주기 위한 음향 유도 나팔을 갖는 스피커로서, 협소한 장소에 실치가 가능하고, 중량과 부피가 소형 경량화되며, 소형 경량이면서도 다수인에게 필요 충분한 레벨의 경보음, 음성 메세지를 알려줄 수 있는 고출력을 낼 수 있고, 소형 경량이면서도 경보음의 확성뿐만 아니라, 음성 메세지를 정확하게 전달하기에 필요 충분한 주파수 특성을 확보한 박형(THIN TYPE)고출력 스피커 유닛 이다.The present invention relates to a thin type (THIN TYPE) high-power speaker unit, the conventional speaker is bulky, it is difficult to reduce the size and light weight, according to the jig jig sound path configuration or trumpet type horn structure, it is unsuitable for indoor installation, etc. In the case of a speaker using a piezo element provided as an output small speaker as a vibrator, the piezo element is limited to a high range due to its frequency characteristics, and only the alarm sound (siren sound) of a specific frequency is reproduced because the tone is degraded. There is a problem that it can be copied, and is not suitable for the amplification of the voice signal. The present invention comprises a driver unit and a housing, a compression chamber in which the audio signal output from the driver unit is compressed to high pressure, an acoustic radiation nozzle for copying the audio signal compressed in the compression chamber and connected to the compression chamber, And an acoustic resonance and reflection trumpet, which is connected to an acoustic radiation nozzle and resonates and amplifies the audio signal copied from the acoustic radiation nozzle, and also switches the sound transmission path of the amplified audio preference. A speaker with an acoustic guidance trumpet for final guidance and amplification of the amplified and inverted audio signal from the acoustic resonance and reflection trumpet into the space, which can be mounted in a narrow space, and the weight and volume are small, light weight, An alert that can alert the majority of people to a sufficient level of sound and voice messages It is able to have a small, lightweight, yet audible alarm of accuracy, as well as accurately delivered to a thin (THIN TYPE) high-power speaker unit sufficient frequency characteristics required for voice messages.
