Abstract
An electromagnetic vibrator for generating vibrations in bone conducting hearing aid devices. The vibrator includes a magnetic device, a vibrator plate and an inner spring member providing an air-gap between the magnetic device and the vibrator plate. The vibrator is housed in a casing and an outer spring is arranged between the vibrator and the casing to isolate movements of the magnetic device relative to the casing. The outer spring is part of the surrounding casing and is mechanically attached to the vibratory transmitting element via an elastic sealing element. The sealing function of the hearing aid housing is provided by the outer spring attachment.
