PROBLEM TO BE SOLVED: To provide an attachment for eyewear of simple device configuration, capable of transmitting the necessary sound reliably, without compromising the fit of an eyewear, and to provide an eyewear including the same.SOLUTION: An attachment 30 is attached to an eyewear 10 and used. The attachment 30 includes a body 32 that is attached to the frame 20 of the eyewear 10, and a bone conduction part 34 coming into contact with the wearer of the eyewear 10, when the body 32 is attached to the frame 20, and can transmit sound by bone conduction. The attachment 30 has a vibration generating part 36 for generating vibration, and can transmits a vibration sound incident to vibration of the vibration generating part 36 to the wearer via the bone conduction part 34.SELECTED DRAWING: Figure 1 |
