Abrégé
(EN)

A loudspeaker comprises a panel member (11, 21, 31, 41, 61, 71, 81, 91) as resonant acoustic radiator relying on bending wave action and a driver (12, 22, 32, 42, 62, 72, 82, 92) coupled to the panel member to cause bending waves therein. The panel member has its mass and/or bending capability of the panel member locally altered or otherwise different, particularly locally of the driver as coupled to the panel member. Local holes (16, 26, 36, 46), affixed mass (66) or affixed damping material (76) are effective to reduce high frequency due to drumming effects at the driver coupling (17, 37, 47, 67, 77, 87).

확성기는 굴곡파작용에 의존하는 공진음향 라디에이터인 패널부재(11,21,31, 41,61,71,81,91)과 상기 패널부재에 결합되어 굴곡파를 일으킬 드라이버(12,22,32, 42,62,72,82,92)를 포함한다. 패널부재는 부분변형되거나 혹은 특히 패널에 결합된 드라이버에 국한하여 상이하게된 패널부재의 질량 및/또는 굴곡성을 갖는다. 부분호올(16,26,36,46), 추가된 질량부(66) 및 추가된 감쇠재료(76)는 드라이버 커플링(17,37,47,67,77,87)에서의 드럼진동효과에 의해 고주파수를 감소시키는데 효과적이다.
