Provided is a fabric-like transducer that is flexible by using a general-purpose fiber material and producing a conventional knitted or knitted fabric structure. Furthermore, an actuator and a speaker are provided by inputting an electric signal to the transducer. A transducer having an electric signal as an input includes two conductive fibers 2 and one piezoelectric fiber 1, which are substantially in the same plane, the conductive fiber 2, the piezoelectric fiber 1, The conductive fibers 2 are arranged in the order. The piezoelectric fiber 1 is a fiber having piezoelectricity. The piezoelectric fiber 1 is made of a piezoelectric polymer. [Selection figure] None |
