PROBLEM TO BE SOLVED: To provide a speaker formed with a screen as a unitary block in which mutual interference between channels is scarcely generated in a multi-channel configuration and which has a high sound quality and a wide sound range and is extremely flexible, light-weight, and reduced in size when stored and easy to be carried, because winding and extending are easy. SOLUTION: The speaker formed with screen as a unitary block includes a screen (S) consisting mainly of a sheet-like base material and an exciter (EX) attached to the rear surface of the screen (S). It is preferable that an excitation plate (EP) be arranged between the exciter (EX) and the screen (S). COPYRIGHT: (C)2007,JPO&INPIT
