International ClassH04R 25/00AbstractActive otoplastics (3) with integrated earpieces (4) are to be acoustically optimized. There is provision here for forming a sound outlet (8) into the otoplastic in accordance with acoustic conditions. If the sound outlet (8) has the form of an exponential horn, this results in advantages for supply of high tones. The earpiece (4) can be secured with the aid of an adapter (5) into the otoplastic (3) so that it can be exchanged.Other References
