发明名称 Exponential horn loudspeaker suitable for cold environments
摘要 An exponential horn loudspeaker is made suitable for cold environments without using an additional heating device in that several parts are made integrally as a moulded metal part. The heating of this moulded metal part can thus be advantageously used to prevent deposition of ice and snow. <IMAGE>
