摘要： A headphone includes an acoustic pipe, a loudspeaker unit, a microphone unit and a feedback circuit. The acoustic pipe has an inner diameter substantially equal to that of an external auditory canal. The acoustic pipe has a mounting portion provided at an end thereof for being mounted on the outer ear and has an acoustically non-reflective end at the other end thereof. The loudspeaker unit is provided on one side of the acoustic pipe with a sound emitting face thereof opposed to the inside of the acoustic pipe. The microphone unit is provided on the one side of the acoustic pipe with a sound collecting face thereof opposed to the inside of the acoustic pipe. The feedback circuit feeds back an output signal of the microphone unit to an input side of the loudspeaker unit. The feedback circuit includes an equalizing section. The output signal of the microphone unit is supplied to the loudspeaker unit by way of the equalizing section. The equalizing section has an open loop characteristic wherein an attenuation characteristic in a frequency band other than a frequency band in which noise can be canceled rises higher than an attenuation characteristic in the frequency band in which noise can be canceled.

The first light signal terminal comprises a separating device for separating a multiplexed light signal in which first and second light signals are multiplexed, first and second light-sensing devices for receiving the first and second light signals thus separated, a detecting circuit for generating a detection signal on the basis of a received output of the second light-sensing device, and a first light emitting device controlled by the detecting circuit so that the first light emitting device emits a third light signal of sufficiently high output level when the second light signal is detected by the detecting circuit and that the first light emitting device emits a third light signal of low output level or disabled when the second light signal is not detected by the detecting circuit. The second light signal terminal comprises a third light-sensing device for receiving the third light signal, second and third light emitting devices for emitting the first and second light signals, and a multiplexer for multiplexing the first and second light signals to provide the multiplexed signal.
