とが困難である。In the above-mentioned conventional auricle-type headphones, since there are few restrictions on the size, it is possible to design a good frequency characteristic from the low range to the high range. On the other hand, each time you wear it, your ear (auricle)
It is difficult to stably obtain the sound image localization because the relative position to and is easily changed.

難い。On the other hand, in the in-ear type headphones, since they are used by putting them in the ear, the relative position hardly changes, so that the sound image localization can be stabilized.
On the other hand, in addition to the size and structural restrictions that it can be used in the ear, there is only a small vibration system built in, so it is difficult to obtain low-frequency (low frequency component region) linearity.

不愉快なものであり、音像定位効果を低下させるもので
ある。That is, as shown in FIG. 9, in the conventional in-ear type headphone frequency characteristic, the sound pressure level of the second harmonic distortion component (2ndHD) and the third harmonic distortion component (3rdHD) is low frequency component region. (20Hz-150H
z) is about -30 dB, and sufficient linearity of the waveform in the low frequency component region cannot be ensured.
Distortion is emphasized and natural bass cannot be played.
As a result of experiments, it was found that such a distorted sound sounds like it is reproduced in the ear and is difficult to localize outside the head. In addition, such a special low tone is unpleasant to the listener and reduces the sound image localization effect.

る。In the low frequency component region (20 Hz to 1
At 50 Hz, the sound pressure level of the second harmonic distortion component (2ndHD) and the third harmonic distortion component (3rdHD) is approximately −
If it is lowered to 40 dB to about -50 dB (when the distortion rate is suppressed to 1% or less), a natural low tone with little distortion can be reproduced. Ideally, about -50 dB is realized.

A signal from a sound source is processed on a time axis to localize a sound image, for example, Japanese Patent Laid-Open No. 6-178.
A sound image localization control method as described in Japanese Patent No. 397 can be used. In this method, a convolution operation circuit on the time axis is only required as a circuit for actually processing a sound image, and the circuit can be made extremely small and inexpensive.

When the signal X from the sound source is input, the low frequency component Y is extracted from the signal X through the low pass filter 15, and the subtraction circuits 16L and 16R extract the signal Y of the low frequency component from the sound source. Difference signal (X−Y) from the signal X, that is, the signal of the middle and high frequency components (X−
Y) is generated, and the signal (X-Y) is subjected to sound image localization processing by the sound image localization processing circuits 17L and 17R, and then the amplifier 18
It is amplified by L and 18R, and reproduced by each in-ear type headphones 12 and 12 of the headphones 11L and R.

られる。As described above, since the sound image localization processing is performed only on the middle and high frequency components having a strong sense of localization and the sound is reproduced by the in-ear headphones 12, the sound image localization effect can be further enhanced, and the low frequency range with a weak sense of localization can be obtained. Since the components are reproduced by the auricle-type headphones 13 without sound image localization processing,
It has almost no effect on sound image localization. Furthermore, since the in-ear type headphones 2 hardly reproduce the low frequency components and the auricle type headphones 13 reproduce only the low frequency components, distortion is small and sufficient bass can be obtained.

向上する。The sound image localization processing circuits 17L and 17R transmit signals to the in-ear type headphones 12 for the time required for the sound to propagate the distance between the sound emitting surface of the in-ear type headphones 12 and the speaker of the auricle-type headphones 13. Since it is delayed, in-ear headphones 1
The sound reproduced in 2 and the sound reproduced in the auricle-type headphones 13 can be kept consistent, and the sound image localization effect is further improved.

時に聴取することができるようになる。That is, when the distance between the in-ear type headphone 12 and the speaker of the auricle-type headphone 13 is so close as to be negligible, the listener has two heads 1.
Although the reproduced sounds from 2 and 13 can be heard almost at the same time, when the distance between them is large, for example, in order to reduce the feeling of wearing the auricle-type headphones 13, use them apart from the ears like the open type. In that case, two heads 12, 1
There is a time difference between the reproduced sounds from No. 3 and they are heard, and the consistency deteriorates. Therefore, a signal given to the in-ear type headphones 12 closer to the ear is supplied to the auricle-type headphones 1.
By delaying the signal given to 3 by a predetermined time, and more preferably by delaying the distance as described above by the time required for the sound to propagate, the two heads 12, 1
The reproduced sounds from 3 can be matched, and the listener can listen at substantially the same time.

As the processing contents of L and 17R become more complicated, the time delay associated with the calculation becomes too large to be ignored.
As shown in, the delay circuit 20 may be provided in the signal path of the signal given to the auricle-type headphones 13 to correct the time difference due to the processing time. For example, the time delay of the sound image localization processing circuits 17L and 17R is 1000 microseconds,
If the time delay due to the distance between the two heads 12 and 13 is 20 microseconds, the delay time of the delay circuit 20 is 1
