ABSTRACT:
Coaxial loudspeaker arrangements (10) are usually so configured, that the loudspeaker (12) located in the bellmouth (29) of the conical loudspeaker (11), is placed on the pole core (17) of the conical loudspeaker (11). However, the contact of the loudspeaker (11) has a disadvantage, with respect to automated manufacture, because either the connection cables (24) for loudspeaker (12) must be threaded through the pole core (17), or the connection cables (24) must be connected to the soldering joints in the diaphragm (15). It is also known to place the loudspeaker (12) into a preform, and to attach this preform to the edge of the loudspeaker frame (14) of the conical loudspeaker (11). The latter is very costly and detrimental to the acoustical effect. For that reason the invention has the task of indicating a coaxial loudspeaker arrangement (10), which is simplified with respect to automated manufacture, without impairing the acoustical effect. This task is fulfilled in that the pole core (17) of loudspeaker (11 ) is tube-shaped, that the loudspeaker (12) is connected to a receiving arbor (22), and that the shaft (23) of the receiving arbor (22) is pushed into the pole core (17) of the loudspeaker (11), and is securely attached thereto. If the shaft (23) is hollow, the components for a frequency crossover can be integrated into the inside of the shaft (23).
