Abstract (en)

[origin: EP0480160A2] A dome-shaped high-frequency loudspeaker (10) is specified which is distinguished by very small dimensions. The magnetic pot (12) is exclusively attached to a one-piece case part (11) by means of a snapper (32), the latching hooks (35) arranged at the one-piece snapper (32) encircling a collar (25) arranged at the magnetic pot (12). After case part (11) and magnetic pot (12) have been latched together, the diaphragm (21) is exclusively fixed in position between the case part (11) and magnetic pot due to the fact that the part of the diaphragm (21) which rests on the magnetic pot (12) is pressed against the magnetic pot (12) by means of the free end (29) of the piece of tube (28) arranged at the case part (11). <IMAGE>
