  • Patent number: 10172763
    Abstract: A skin and scalp massaging apparatus using acoustic pressure. A vibration member generates vibration using acoustic pressure induced when a sound source is generated. A vibration probe is coupled to the vibration member to receive vibration. The vibration probe has a detachably provided head having various purposes. The head is provided to massage skin or scalp. The vibration probe is coupled to a cone paper damper for generating vibration through a connection member to which the vibration member is coupled. The vibration probe is coupled to the cone paper damper of the vibration member, so that vibration is directly received, and thus, the vibration efficiency can be improved. Further, the head for the skin massage or the scalp massage is detachably provided on the vibration probe, and thus, can be used for various purposes of, for example, massaging skin, scalp, or the like.
