摘要： An acoustic signal reproducing apparatus for supplying an acoustic signal to a headphone device, in which position-detecting reference signals from a reference signal source are sensed by a pair of signal sensors provided at two places over a listener's head. The turning angle and the relative distance of the head with respect to the reference signal source are calculated by processing units on the basis of these signal sensors and transmission characteristics with respect to an arbitrarily positioned imaginary sound source are found from the information concerning the relative distance and the turning angle, with the reference signal source as a reference position. Acoustic signals are processed by acoustic signal processing devices on the basis of the transmission characteristics to realize binaural reproduction with respect to the imaginary sound source. A level detection unit detects when the output level of at least one of the signal sensors becomes lower than a reference level and, on the basis of a detection output of the detection unit, the acoustic signals supplied to the headphone device are controlled by a control unit to realize a stable binaural playback operation, and an alarm is supplied to the headphone device in response to the output of the level detection unit.

摘要： An earphone device includes an acoustic tube having an inner diameter substantially identical to that of the external auditory canal has an ear mounting portion at one end and an acoustic non-reflecting portion at the outer end. An earphone unit and an internal microphone unit are mounted on the periphery of the acoustic tube adjacent each other and communicate with the interior of the acoustic tube with their respective vibration plates facing inwardly of the tube. The phase of the signal representing the external noise in the acoustic tube picked up by the internal microphone unit is reversed and combined with the audio signal fed to the earphone unit. The earphone device also includes an external microphone unit on the outside of the acoustic tube and a variable ratio mixing circuit for mixing the input audio program signal, the reversed phase signal obtained from the internal microphone unit, and the signal from the external microphone unit, so that external sounds can be heard without removing the earphone device.

摘要： An acoustic signal reproducing apparatus for reproducing acoustic signals through headphone devices is disclosed. The left channel and right channel acoustic signals are provided by a device for processing the transmission characteristics with constant transmission characteristics representing the location of an imaginary sound source relative to both of the listener's ears. The left channel and right channel acoustic signals, processed in this manner by the device for processing the transmission characteristics, are provided by an acoustic signal processing device with a level difference and a time difference consistent with changes in orientation of the user's head. In this manner, optimum binaural reproduction with respect to the imaginary sound source may be achieved.

摘要： In the audio signal reproducing apparatus, information on the transfer characteristics representative of the transfer characteristics from virtual sound sources to both ears of a listener in at least a first quadrant of the rotational angular position of the head M of the listener is stored in storing unit 22. The transfer characteristics in rotational angular position of the head M represented by detection outputs from detecting unit 5L, 5R and 13 for detecting the rotational angle position depending upon the movement of the head of the listener are formed based upon the transfer characteristics information of at least the first quadrant stored in the storing unit and left and right channel audio signals are processed by audio signal processing unit 23 for achieving a proper binaural reproduction relative to the virtual sound sources. Also in the audio signal processing apparatus of the present invention, information on the transfer characteristics from virtual sound sources to both ears of a listener for each given rotational angle depending upon the movement of the head M of the listener is stored in storing unit 62. The rotational angular position of the head of the listener is detected by detecting unit 45L, 45R and 53 at a solution higher than that of the information of the transfer characteristics stored in said storing unit. The information on at least two transfer characteristics in the vicinity of the rotational angular position represented by the detection outputs from detecting unit is read from the storing unit. The information on the transfer characteristics in the rotational angular position of the head represented by the detection output is interpolation operated by interpolation operating unit 61. Based upon the information on the transfer characteristics determined by the interpolation operation unit, left and right channel audio signals are processed by audio signal processing unit 63 for achieving a proper binaural reproduction relative to the virtual sound sources.
