Abstract: A sound anchor for transmitting a sound and vibration to human tissues in an ear canal is provided. The sound anchor includes a first link, and an anchor which is fixed to an ear canal inner wall of a user, receives the sound and vibration from the first link, and transmits the sound and vibration to at least one of an ear canal bone portion, a bone portion skin surface, and an auditory ossicle protrusion portion of an eardrum. The anchor includes a bar-shaped connection portion and an ear canal contact portion which is installed in the connection portion. The ear canal contact portion includes a first contact portion which is installed in one end portion of the connection portion and is in contact with the skin surface or the bone portion, and a second contact portion which is installed in the other end portion of the connection portion and is in contact with the skin surface or the bone portion. The first link is attachable to or detachable from the anchor.

Abstract: A mouse according to the present invention, comprises: a casing; a button part disposed on the casing, for generating a click signal by being pressed; and a sensing part fixedly disposed on the casing in the vicinity of the button part in such a fashion as to be slantedly lower than the button part; an amplifying part built in the casing, for amplifying the clock signal generated from the sensing part, up to a predetermined level; a filtering part built in the casing, for regulating the signal amplified by the amplifying part, up to a predetermined level; and a switching part for outputting selectively and one from the signals applied thereto from the button part and the sensing part. Since the mouse operates in a touch-sensor fashion, clicking noise is avoided when in use.
