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>
