Abstract

To suppress internal pressure of an external auditory meatus due to sound pressure and to lower feeling of sound volume accompanying suppression.SOLUTION: An inclined groove for adjusting internal pressure (a sealing degree) of an external auditory meatus depending on a mounting position is provided on an upper portion of a main body, and a sound hole of 4 square millimeters or less in total is provided on an adjustment inclined groove to relatively suppress internal pressure of the external auditory meatus. The adjustment inclined groove compensates for decrease in perceived sound volume with a positional structure in which resonance of the external auditory meatus is easily obtained.SELECTED DRAWING: None
