PURPOSE:To add easily a speaker device for monitor without increasing greatly the capacity and weight of a tape recorder as a whole by providing a speaker unit attachably and detachably to the case of the tape recorder or a cassette cover. CONSTITUTION:A speaker unit 9 is assembled in the following procedure. That is, a sheet 21 is first pasted to a store ring 22, and a punching panel 19 and then a speaker 17 are fitted into the ring 22. Lead wires 18 and 18' are soldered to contact terminals 14 and 14' of an attachment bracket 10 respectively. Then the bracket 10 is put into the ring 22. The unit 9 with which the assembly is over is attached to a case 2 by first fitting attachment legs 12 and 12' to large opening parts of attachment holes 11 and 11' at the side of the case 2. Under such conditions, the ring 22 is held by hands and turned toward an arrow A. Thus the terminals 14 and 14' have contacts with sliding terminals 13 and 13', and therefore the unit 9 is electrically connected to the internal circuit of a tape recorder main body 1. Then the reproduced signal is led out. |
