[0038] In this way, by providing the exhaust fan 41 and the first heat sink 5, the heat generated by the functional module 2 is taken away by the airflow, so that the device maintains a suitable operating temperature, reduces the possibility of high-temperature damage, and increases the service life.

[0039] In some feasible embodiments, the mounting base plate 1 is in the shape of a rectangular plate, the shell 3 is in the shape of a rectangular cylinder, the functional module 2 is the electronic circuit part of the audio signal distributor, and the exhaust fan 41 is installed on the side of the shell 3.
