Abstract: PURPOSE:To remove an oppressive sensation and to obtain a good stability outside a head by making the opening end part of an opposite side to the ear insersion part of an acoustic tube into a sound non-reflection end. CONSTITUTION:The respective one opening end parts of a pair of acoustic tubes 1L and 1R are made into a pair of ear insersion parts 2L and 2R. An acoustic signal being reflected by respective tympanums pL and pR is propagated toward the opening end parts 3L and 3R of the other side corresponding in the respective sound tubes 1L and 1R, however the opening end parts pL and pR of the other side are made a sound non-reflection end. Consequently, the acoustic signal which reaches the respective tympanums pL and pR and is reflected by the tympanums pL and pR no longer reaches the respective tympanums pL and pR again. Thus, the sense of a normal position inside the head and the generation of the oppressive sensation are prevented.

Abstract: PURPOSE:To prevent a voice reflected in an eardrum from being reflected again toward the eardrum and to allow the device to cope with various sizes of external auditory means by fitting a removable mount member to one end of an acoustic tube formed to have nearly the same inner diameter as that of an external auditory meatus and forming the other end as a nonreflective termination for a voice. CONSTITUTION:The acoustic tube 1 formed to have nearly the same inner diameter (w) as that of the external auditory meatus A and a speaker unit 2 mounted to one end of the acoustic tube 1 while a sounding face 2a is faced in the inside of the tube are provided to the device. Then an ear mount member 4 to be mounted to an entrance C of the external auditory meatus A is fitted removably to a mount member fitting position 6 at one end of the acoustic tube 1 and the other end is formed to be a nonreflective termination of voice. Thus, the incident sound is not reflected again at the other end of the acoustic tube 1 toward the eardrum B and the device can cope with the external auditory meatus A of various diameters.

Abstract: PURPOSE:To promptly, high-accurately, and stably detect the change of the direction of the head part of a listener by calculating the above-mentioned change based on the phase difference between the output signals of a pair of microphones to be arranged at two parts in the head part to pick up a detecting signal to be outputted from a detecting sound source. CONSTITUTION:For a headphone device 2, first and second microphones 3 and 4 are arranged for mutually separated two parts. A speaker 5 to be the detecting sound source is fixed and arranged to a position separated from the listener. An ultrasonic signal in a non-audible band is supplied from an ultrasonic signal source 7 to this speaker 5, and the speaker 5 outputs an ultrasonic wave to be the detecting signal. This ultrasonic wave is a so-called acoustic wave such as a bust wave for which the detection of its phase is made possible. The output signals of the microphones 3 and 4 are the signals obtained by picking up the acoustic wave to be outputted from the speaker 5, and an arithmetic unit 8 calculates the change of the direction of the head part based on the phase difference between the output signals of both the microphones and respectively processes the acoustic signals of a left channel and a right channel from an acoustic signal supplying source 16 based on transmission characteristics corresponding to the calculated direction of the above-mentioned head part.
