<p>[Problem] To provide a multifunction-type vibration actuator which, even when thinned down, can easily secure a sound pressure and a vibration amount for tangible vibration output. [Solution] By configuring a housing in the shape of a ring and adding a reinforcement structure using a sound propagation diaphragm, etc., it is possible to project a magnetic circuit unit from the housing. By employing such a configuration, the multifunction-type vibration actuator described in the present application is able to secure a sound pressure due to the vibration of a fitting case and a vibration amount due to the expansion of a projected magnetic circuit unit, even when the vibration actuator is thinned down.</p> |
