In the figure, 10 a is a first electrode provided on the surface of one mounting shaft 3 and electrically connected to the positive electrode of the speaker body 2 as a mounting shaft side electrical contact, and 10 b is the other mounting shaft 3 Is a second electrode as an attachment shaft side electrical contact that is provided on the surface of and is electrically connected to the negative electrode of the speaker body 2.

Reference numeral 11 a denotes a first electrode receiver provided on one bearing 5 as a bearing-side electrical contact for contacting the first electrode 10 a and transmitting an input signal to the positive electrode of the speaker body 2, and 11 b denotes the other electrode. The second electrode receiver is provided on the bearing 5 and serves as a bearing-side electric contact for contacting the second electrode 10b and transmitting an input signal to the negative electrode of the speaker body 2. Further, the electrodes 10a and 10b and the electrode receivers 11a and 11b are configured to maintain a contact state with each other even when the cabinet 1 turns.

In such a speaker device, by transmitting the input signal to the speaker body 2 by the electrodes 10a, 10b and the electrode receivers 11a, 11b provided between the mounting shaft 3 and the bearing 5, the cabinet is Since it is not necessary to directly attach the cable to the cabinet 1, the cabinet 1 can be freely swung without being restricted by the cable, and disconnection of the cable due to the swiveling of the cabinet 1 is prevented.

Example 2. Next, FIG. 2 is a schematic configuration diagram showing a speaker device according to a second embodiment of the present invention.
