DEVICE HAVING FLEXIBLE SUBSTRATE

摘要

A speaker (10) has: a flexible substrate (50) that includes a vibration circuit section (59), which has voice coil wiring (60) formed thereon and functions as a planar acoustic transducer, and a drive circuit section (58) for supplying an acoustic signal to the voice coil wiring (60); a housing (20) for housing the flexible substrate (50); and magnetic plates (31, 32) that are arranged so as to sandwich the vibration circuit section (59). The flexible substrate (50) further includes slits (55) that are formed between the vibration circuit section (59) and the drive circuit section (58).
