The invention relates to a converter system, for instance for a light emitting device, comprising: a first material, which comprises, preferably essentially consists of an emitting material, emitting a color of interest, and is essentially free of sensitizer material, a second sensitizer material, which is essentially free of the first material and absorbs light (is excitable) in the wavelength range of interest and its emission spectrum overlaps at least partly with one or more excitation bands of the first material.

A hearing device, particularly a hearing aid, has a housing, a signal processing unit arranged in the housing, a first sound generator disposed in the housing, and a second sound generator. The first sound generator and the second sound generator are configured to convert an output signal from the signal processing unit into sound. The second sound generator is a thermo-acoustic transducer.
