As described above, in the conventional headband 1, the connecting parts 4, 6 and the receiver supporting parts 5, 7, etc. are connected at the connecting portion between the bands 2, 3 and the receiver supporting parts 5, 7. The metal part is exposed. Therefore, in the headband 1 having such a configuration,
When worn, especially in subjects with long hair, such as women, the hair may be entangled with metal parts, and there is a problem of poor usability. Generally, an auditory test is performed on a large number of subjects having different head shapes, and therefore, the position adjustment of the receivers 22 and 28 is required many times a day. However, as described above, the conventional headband 1
There is no particular clue for raising and lowering the supports 21 and 26, and therefore, the receivers 22 and 28 for each subject
However, there is a problem in that it is inconvenient to use in that the position adjustment work is complicated.

Further, as described above, in the conventional headband 1, since the metal portion is exposed, the headband 1 has a cold feeling in appearance and touch, and thus the subject suffering from the disease has a feeling of anxiety and fear. Was given. Further, as described above, in the conventional headband 1, the joining metal fitting 4,
The use of a large amount of sheet metal for the handset 6 and the handset supporting brackets 5, 7 and the like has a problem that the manufacturing cost is high and the assembly is complicated. Furthermore, in the hearing test, FIG.
As shown in the figure, not only the case of using the air-conducting handset 22 and the bone-conducting handset 28 but also a pair of air-conducting handset 22
In some cases.

In the latter case, since the human ears are located substantially symmetrically through the head, it is not necessary to adjust the positions of the air-conducting handsets 22 with respect to each other. However, in the former case, the air-conducting handset 22 must be against the subject's ear and the bone-conducting handset 28 must be against the mastoid at the back of the ear. That is, in such a case, the receivers 22 and 28 are not symmetrical but have a shifted positional relationship. Therefore, the adjustment is required. Conventionally, in order to solve this point, two types of the receiver supporting bracket 5 for enabling the headband 1 to swing back and forth as described above and the receiver supporting bracket 7 for restricting the swing are prepared. These measures have been dealt with by exchanging them, but the number of parts has been increased and this has been complicated.

The present invention has been made in view of the above points, and is intended to propose a user-friendly headband.
