| 发明名称 | Electroacoustic transducer | ||
| 摘要 | An electroacoustic transducer includes a diaphragm including: a wing-pair portion; and a cone portion. The wing-pair portion includes a pair of convex surfaces having respectively convex surfaces of a pair of longitudinal split tubular members. A valley is formed between one side portions of the pair of convex surfaces. The cone portion surrounds an outer peripheral portion of the wing-pair portion and extends in a conical shape. The electroacoustic transducer further includes: a converter configured to convert between a vibration of the diaphragm in a depth direction of the valley and an electric signal corresponding to the vibration; and a supporter supporting an outer peripheral portion of the cone portion to allow the diaphragm to vibrate in a direction of the vibration. | ||
