PROBLEM TO BE SOLVED: To provide a bone conduction speaker unit for a head mounting means simply configured to move this bone conduction speaker unit to a position which does not become obstructive to the attachment/detachment of a helmet or the like when not using by a simple operation, and to prevent any pain due to its long-time wearing. SOLUTION: This bone conduction speaker unit is provided with a speaker main body 1 with a bone conduction speaker built-in and a side leading abutment surface arranged, a supporting arm 2 for supporting the speaker main body 1, a supporting plate 3 for axially supporting the supporting arm 2 rotatably in a vertical direction, and a fixing member 4 for axially supporting the supporting plate 3 rotatably in a vertical direction orthogonal to the rotating direction of the supporting arm 2. At the time of mounting the bone conduction speaker unit through the fixing member 4 on the head mounting means, the supporting arm 2 is rotated outward against the supporting plate 3 according to the rotating operation of the supporting plate 3 against the fixing member 4.
