Document Type and Number:
WIPO Patent Application WO/2022/196353
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an electroacoustic converter in which an acoustic film is affixed to a rollable panel, the electroacoustic converter making it possible to prevent the panel from being scratched by wiring and to output sound having a high sound pressure. The aforementioned problem is solved by having a rollable panel, an acoustic film that causes the panel to vibrate, a rolling shaft for rolling the panel, and flat-plate wiring for connecting the acoustic film and an external device, the flat-plate wiring including a metal foil, and the invention being such that flat-plate wiring having a length of at least 50% of the length of the panel in a direction orthogonal to the rolling shaft is affixed to a region that is no more than 30% of the length of the panel in the axial direction of the rolling shaft from the axial-direction end section of the rolling shaft.
