Cassette includes a disc (1) accommodated in an external sleeve (2) and retained therein by a disc holder (7) which closes the front of the sleeve (2) by means of a shutter (8), which retains the disc by retaining jaws (9), and which is latched in the sleeve by latching means (48) which can be moved by external means to remove the disc holder and the disc from the sleeve. Apparatus includes release levers (11) which release the disc holder (7) and an extraction mechanism (11, 13, 14) which withdraws the disc-holder/disc unit from the sleeve in such a way that the disc and disc holder remain inside the apparatus after withdrawal of the sleeve. Jaws (9) also retain the disc (2) outside the sleeve and can be moved relative to each other from the retaining position to a free position, in which the disc can be rotated and is clear of the retaining means, by external means only. Apparatus includes release means (11, 15, 20, 24) which ensure that inside the apparatus the jaws (9) are moved from the retaining position to the free position.

System for recording/reading information on/from a disc, comprising a

A hearing aid includes a duct (10) for transmitting the sound from the receiver (2) to the exterior of the housing (1) of the hearing aid. The duct is formed in a component (9) which is constituted by a body of an elastic damping material and which also serves as the sole suspension means for the receiver (2). The suspension means supports the receiver mainly on that side of the receiver where the sound outlet (12) of the receiver is located. This minimizes the mechanical-acoustic coupling between the receiver and the microphone (3) of the hearing aid.
