ABSTRACT:
A bottom base15aof a transportable mixer M is provided with internal threads16a, while the upper end of a stand20is provided with external threads25awhich engage the internal threads16a. The mixer M is adapted to be mounted on the stand20by the threaded engagement between the internal threads16aand external threads25a. Furthermore, a groove15is provided on an under surface14of the mixer M, the groove15extending from one end of the under surface14to the other end through the center. On the groove15there are provided the internal threads16a. The mixer M is formed to have a low front part and a high rear part, such that a top surface11of the mixer M has a low front part and a high rear part when placed on a table26, and stays on a substantially horizontal position when mounted on the stand20. As a result, a transportable electro-acoustic apparatus capable of being fixed on and supported by a stand is provided.
