Abstract: An installation structure of a vibrator includes elastic members formed of an elastic material, the elastic members being arranged between a housing of a listening device, and the vibrator accommodating an electromechanical transducer for transducing an electric signal into mechanical vibration. The vibrator is installed on the listening device such that a lower surface of the vibrator is disposed at a position facing an ear cartilage in a state where the listening device is worn on an ear, and a first mechanical impedance of the elastic members between the vibrator and the housing is set smaller, at a frequency of 200 Hz to 1000 Hz, than twice a second mechanical impedance, with which the vibrator is loaded, of the ear cartilage.
