FIELD: acoustics.

SUBSTANCE: spectacles containing a bone conduction microphone. The claimed spectacles include a spectacle body comprising a spectacle frame and two spectacle arms, the two spectacle arms respectively being physically connected to the spectacle frame; and at least one bone conduction microphone configured to convert the vibration signal into an electrical signal. In this case, the said at least one bone conduction microphone is physically connected to the spectacle frame or at least one spectacle arm of the two spectacle arms, and the said at least one bone conduction microphone is configured to receive vibration signals from the spectacle frame, from the said at least one spectacle arm or from the user's body. Moreover, these two spectacle arms contain a contact surface that is in direct contact with the user, and the pressure of the contact surface on the user’s body exceeds 0.1 N.

EFFECT: increased vibration signal received by the bone conduction microphone.
