Abstract

Der Lautsprecher weist einen Konus (2) und eine mit dem Konus (2) verbundene Sicke (4) auf. Sie besteht aus einer spritzfähigen, in verfestigtem Zustand weichen Kunststoffschicht. Der Herstellung des Lautsprechers dient ein Verfahren, bei dem eine offene Negativform (16) verwendet wird, in welcher der Konus (2) angeordnet und befestigt wird. Anschließend wird der Kunststoff in die offene Negativform (16) aufgesprüht und die Sicke (4) in Form der weichen Kunststoffschicht gebildet, die sich mit dem Konus (2) verbindet.
