ABSTRACT:
The invention specifies a calotte-type (encased) loudspeaker distinguished by very small dimensions. The pot magnet (12) is joined to a single-piece case component (11) exclusively by means of elastic snap catches (32) such that a terminal locking hook (35) forming an integral part of the said snap catches (32) engages with a collar (25) arranged on the pot magnet (12). After the case component (11) and the pot magnet (12) have been joined together, the membrane (21) is kept in position between the case component (11) and the pot magnet (12) exclusively by virtue of the fact that the part of the membrane (21) that bears against the pot magnet (12) is pressed against the said pot magnet (12) by the free end (29) of the piece of tubing (28) attached to the case component (11).
