Bone conduction hearing aid

A hearing aid intended to be disposed around a user's ear comprising at least a first bone conduction device and at least a second bone conduction device, the first bone conduction device configured to be positioned in contact with a first bone area of a user's head and to transmit first vibrations to said first bone area, and the second bone conduction device configured to be positioned in contact with a second area of the user's head and to transmit second vibrations to said second bone area, said second bone area being different from the first bone area, and said first bone area and said second bone area being located around the same ear of the user, said hearing aid further comprising at least one microphone making it possible to capture a surrounding sound signal which is then transformed to generate the first and second vibrations, the first and second bone conduction device each comprising a main body, a base configured to be placed on the skin of the user, and an intermediate part which connects the main body and the base so that the base is able to move relative to the main body in order to generate the vibrations and to transmit said vibrations to the user.
