    Abstract: The loudspeaker comprises a cone (2) and a beading (4) attached to the cone (2). The beading (4) is composed of a sprayable plastic layer which is soft in its solid state. The manufacture of the loudspeaker is facilitated by a process in which an open negative mold (16) is used in which the cone (2) is arranged and immobilized. Following this, the plastic is sprayed into the open negative mold (16) and the beading (4) is formed as a soft plastic layer which attaches itself to the cone (2).

    Abstract translation: 扬声器包括锥体(2)和连接到锥体(2)的滚珠(4)。 珠粒(4)由可固化的软性塑料层组成。 扬声器的制造通过使用其中锥体(2)被布置和固定的开放的阴模(16)的方法来促进。 之后,将塑料喷射到开放的负模具(16)中,并且将卷边(4)形成为将其自身附接到锥体(2)的软塑料层。
