Abstract
Plug for miniature receiver, especially for pocket hearing aids for the hard-of-hearing, with a plug body (7) and at least one plug pin (9) projecting out of the plug body (7). In order to avoid a gap between the receiver and the plugged-in plug, and therefore avoidance of escape of sound, it is suggested that the plug body (7) should be provided with a circumferential bulge (11, 14) of elastic material, surrounding the plug pin (or pins), which lies as a sealing ring on the receiver (1) when the plug is plugged in, thus acoustically sealing the gap between the receiver housing and the plugged-in plug.
