ABSTRACT:
A driving apparatus for driving an electro-acoustic transducer has a main body portion and a control information storage body which is arranged independently of the main body portion and is selectively separated from or coupled to the main body portion, as needed. The control information storage body stores a real circuit or information for setting electrical characteristics of the driving apparatus. In addition, the driving apparatus has a protection circuit for preventing a disadvantageous result of the driving apparatus and a load caused by an unstable operation and the like when the control information storage body is attached/detached to/from the main body portion or when an inappropriate control information storage body is loaded onto the main body portion.
