An electro-dynamic exciter includes a magnetic circuit assembly composed of an outer yoke having a cylindrical peripheral wall, and a bottom wall connected to one end of the peripheral wall, a flat magnet located within the outer yoke and placed on the bottom wall of the outer yoke, and a flat inner yoke placed on the magnet. A magnet gap is defined between the outer yoke and the inner yoke. The magnetic circuit assembly is vibrationally supported on a support panel by means of a flexible carrier. The support panel is located in a face-to-face relation to the other end of the peripheral wall of the outer yoke. The flexible carrier is made from a flexible sheet material. The flexible carrier includes an annular anchor section secured to the support panel, a cylindrical section connected to the anchor section and coaxially extending into the magnetic gap, a flexible section extending radially inwardly from the anchor section toward the inner yoke and secured to the inner yoke. The magnetic coil is wound around the cylindrical section.
