Abstract
A mobile audio system includes a mobile audio instrument having no internal amplifier, a first connector fixedly mounted on the back face of the instrument, a mounting and demounting unit for supporting the mobile audio instrument in a detachable manner, a second connector fixedly mounted on the mounting and demounting unit and having contacts each of which is electrically connected with the corresponding one of the contacts in the first connector and an external amplifier fixedly mounted on the mobile audio instrument and for amplifying line outputs from the second connector. Since the mobile audio instrument has no internal amplifier, the mobile audio system can be reduced in size and weight and improved for portability. In addition, the number of contacts can be reduced and the number of different types of contacts is decreased.
