Abstract
To provide a bone-conduction earphone microphone provided with adequate noise control measures for workers working in a noisy workplace, thus enabling the workers to perform smooth communication with other people. The bone-conduction earphone microphone has a configuration in which a bone-conduction sound vibration unit 110 and a projection part 11 connected thereto are formed in a main body 1, and a core part 20 of a polyurethane first earplug section 2a and the projection part 11 are connected, facing each other, by a tubular connection section 30. This configuration enables the bone-conduction earphone microphone to provide hearing protection by acting as a high sound-insulation earplug for an ear canal, and also to perform input and output of voices by means of bone-conduction sound vibrations without picking up noises.
