Abstract
A behind-the-ear hearing aid is provided with an electric/acoustic transducer unit with a loud-speaker housing (53) in which there is a loud-speaker membrane 54. The housing (53) is spring-mounted in a capsule (59) in such a way that the capsule (59) and the loud-speaker housing (53) define an intermediate space (U53). The front (R1) of the membrane (54) is connected to the acoustic output (S) of the hearing aid, while the back (R2) is coupled to the intermediate space (U53) via coupling holes (55).
