Abstract

The invention relates to an air pressure generator for generating pressure pulses for the treatment of ears, said pulses being intended to be applied for instance to the external auditory meatus of an ear, said generator comprising a housing (1, 101, 201, 301) and a flexible membrane (16, 116, 216, 316) located in said housing and means (7, 107, 207, 307, 9, 109, 209, 309) for actuating said membrane. The membrane and said housing form a chamber (24) connected by suitable connecting means (23, 37, 40, 41, 35) to the ear (36), said chamber and said connecting means forming a closed system in the working position of the generator, said pressure pulses being generated by the direct action of the displacements of said membrane caused by said actuating means on the enclosed air in said closed system.
