| 发明名称 | Suspension for a sound transducer | ||
| 摘要 | An object of the present invention is to provide a suspension for a sound transducer which has a central portion serving as a center diaphragm and which has a cover layer and a copper pattern partially removed to prevent a decrease in sound pressure from being caused by an increase in weight of a vibration system. According to the present invention, there is provided a suspension for a sound transducer which includes a central portion, a peripheral portion, and a support portion for connecting the central portion to the peripheral portion, the suspension comprising: a base film, a conductive film attached on the base film by means of an adhesive, and a cover layer attached on the conductive film by an adhesive, wherein at least part of the cover layer disposed on the central portion is removed. | ||
