주 확성기 진동판의 완전한 이용을 허용하도록 지지되며, 그의 표면이 디스크와 피에조 전기의 "고음역용 확성기" 진동판에 의해 배면으로부터 방출된 방사를 반사시키는 피에조 전기의 "고음역용 확성기"를 갖는 다수의 확성기에 있어서, 피에조 전기의 "고음역용 확성기"가 세라믹 디스크(10)와 진동판(11)으로만 형성되며, 한개 이상의 스포우크를 외부를 향하여 분기시키는 환상형 플랜지로 형성되는 지지 바스켓(12)수단에 의해 주 확성기 진동판(2)앞에 위치하며, 확성기의 단부는 주 확성기 바스켓(1)에 고정되며, 직경이 최대로 되는 위치에서 진동판(11)의 연부가 상기 환상형 플랜지 내부에 고정되며, 댐퍼로서 작용하는 스폰지 링(13)이 먼저 인가되는 것을 특징으로 하는 확성기.It is supported to allow full use of the main loudspeaker diaphragm, and to a number of loudspeakers having a piezo electric "high range loudspeaker" whose surface reflects radiation emitted from the back by the disk and piezo electric "high-frequency loudspeaker" diaphragms. The piezoelectric "high-frequency loudspeaker" is formed only by the ceramic disk 10 and the diaphragm 11, by means of a support basket 12 formed by an annular flange for branching one or more spokes outward. Located in front of the main loudspeaker diaphragm 2, the end of the loudspeaker is fixed to the main loudspeaker basket 1, and the edge of the diaphragm 11 is fixed inside the annular flange at the position of maximum diameter, acting as a damper. Loudspeaker, characterized in that the sponge ring 13 is applied first. 주 확성기 진동판의 완전한 이용을 허용하도록 지지되며, 그의 표면이 세락믹 디스크와 피에조 전기의 "고음역용 확성기"진동판에 의해 내면으로부터 방출된 방사를 반사시키는 피에조 전기의 "고음역용 확성기"를 갖는 다수의 확성기에 있어서, 피에조 고음영용 확성기가 세라믹 디스크(10)와 진동판(11)으로만 이루어지며, 확성기가 장착되는 판넬앞의 구멍을 커버하는 보호 그릴(14)에 의해 주확성기 진동판(2)앞의 위치에 유지되며, 직경이 최대로 되는 위치에서, 원뿔(11)의 연부가 스폰지링(13)에 접착되며, 차례로, 스폰지링(13)이 그릴(14)의 내부에 제공된 플랜지에 부착되는 것을 특징으로 하는 확성기.Supported to allow full use of the main loudspeaker diaphragm, a plurality of piezo electric "high-frequency loudspeakers" whose surfaces reflect radiation emitted from the inner surface by the ceramic disk and piezoelectric "high-frequency loudspeaker" vibration plates. In the loudspeaker, the piezo high-shading loudspeaker consists only of the ceramic disk 10 and the diaphragm 11, and in front of the main loudspeaker diaphragm 2 by a protective grille 14 covering a hole in front of the panel on which the loudspeaker is mounted. In the position where the diameter is maximized, the edge of the cone 11 is glued to the sponge ring 13, which in turn is attached to the flange provided inside the grill 14. Loudspeaker featured. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
