Abstract (en)

An acoustic radiator (AR) includes a plate-like member (1) which has elastic properties in a driving frequency band for acoustic radiation. The plate-like member (1) is supported by a support portion (3) into a state where a peripheral portion of the plate-like member (1) is allowed to substantially freely vibrate. A driving portion (2a) is disposed along the peripheral portion of the plate-like member (1). The driving portion (2a) causes the plate-like member (1) to perform acoustic radiation when the driving portion (2a) drives the peripheral portion of the plate-like member (1).
