摘要：PROBLEM TO BE SOLVED: To provide a stereo headphone in simple configuration.SOLUTION: The stereo headphone is provided which compris a speaker, an ear pad and a cartilage conduction vibration source which transfers vibration for using the ear pad as a cartilage conduction vibration part. The cartilage conduction vibration source and the speaker can be independently controlled and driven by audio signals which are equalized differently. When outputting environmental sound from the speaker after pha inversion, no environmental sound is outputted from the cartilage conduction vibration part. The environmental sound is picked up by a microphone and outputted from the speaker so as to be audible. In such a ca, no environmental sound is outputted from the cartilage conduction vibration source. The speaker is supported by the ear pad and cartilage conduction of transferred vibration is performed. Both ends of a piezoelectric bimorph are supported by the ear pad and a diaphragm is provided in a central part as the speaker. One end of the piezoelectric bimorph is supported by the ear pad and a diaphragm is provided in a free vibration part of the other end as the speaker.
