A diaphragm of an electronic sound converter is provided to improve productivity and workability by increasing an adhesive strength between a voice coil and an adhesive plane of a vibration plate. A diaphragm of an electronic sound converter includes a voice coil(1), an adhesive plane(14), and a collection unit(20). The voice coil(1) is adhered to the adhesive plane(14). The collection unit(20) collects and receives a spread adhesive. The collection unit(20) has a predetermined shape along the adhesive plane(14), and grooves at regular intervals. The groove has a long axis and a short axis. The grooves of an elliptic shape are formed radially along the adhesive plane(14). The grooves of a rectangular shape are formed radially along the adhesive plane(14). |
