Output devices and wearable display

Headphones 3 has a pad 31, the enclosure 32 and the dome 33 is a means for adjusting the quality of the audio output by the sound wave emitted from the enclosure resonance, or absorbed, and outputs a voice in contact with a human head ing. The sound absorption dome 33, is not established except components for use in reflection, it is substantially hollow. This internal, using the circuitry supporting part 34 of the shape that does not block the flow of air in the dome, placing the circuit board 35. Such circuit board is built in the other headphones. Each of the circuit board installed in the dome 33 of the headphone is connected by a cable or FPC, is installed inside of the headband 4, it performs the transmission of signals and power. It can be solved the problems of the arithmetic processing unit such housing dimensions radiating issues output device.
