The film speaker unit 100 and the speaker driving unit 200 are configured to be fixedly held by the fixing member 300 as shown in FIG.

The fixing member 300 includes a frame 310 in which a film speaker unit 100 is fixedly coupled to the inside of the frame 300 and a support 320 for supporting the frame 310.

In the figure, in the case of the ferroelectric layer formed by mixing Fe with respect to BLT, the residual polarization value is larger than the ferroelectric layer formed by BLT within a total voltage range of 5 to 30 V, .
