<p>All or part of the material making up the membrane (1) is a methylpentene polymer or a methylpentene copolymer, or a mixture of both, with a small proportion of elastomer. The membrane may be that of a loudspeaker with plunger having a conical, domed or dihedral structure, or that of a microphone with plunger. The material of the above defined membrane can also be that of the centring suspensions (11, 12) or the dust shield (13) in a loudspeaker. It can also be that of the centring suspensions for the membrane of a microphone. <IMAGE></p> |
