Abstract

PURPOSE:To miniaturize an acoustic device by using one of microphone input of the acoustic device in common use for a microphone for binaural headphone, an external general microphone and a line input of other acoustic devices. CONSTITUTION:In Figure, 28 is a binaural headphone and a low pass filter 20 is provided between a binaural headphone main body side, i.e., microphone 19 and a microphone plug 22. In monitoring a microphone at binaural recording, a voice signal from the microphone 19 enters the acoustic device via the microphone 22 and a microphone jack 24 and recorded through a microphone amplifier 26. Simultaneously, the voice signal is fed from the microphone amplifier 26 to a power amplifier 27 and the voice is outputted from a speaker 20 of the headphone via a headphone jack 25 and a headphone plug 26. If the microphone 19 and the speaker 20 are placed nearly and even if a high frequency sound enters the microphone 19 from the speaker 20, the high frequency sound is attenuated by a low pass filter 21, thereby preventing howling.

As shown in Figure 2, when a conventional inaural handphone is attached to a conventional audio device and the microphone is monitored during recording, the signal from the microphone 9 is transmitted from the microphone plug 11 through the microphone jack 14 and into the microphone. At the same time as being recorded through the amplifier 17, the microphone amplifier 17
The output is from Noguwa amplifier 18 to headphone jack 1.
5 and the headphone flag 12 to the speaker 1° of the headphone, so that it can be monitored by sound. At this time, since the microphone 9 and the speaker 1Q are provided close to each other, high-frequency sound in particular enters the microphone 9 from the speaker 10, causing ringing. To prevent this, a low-pass filter 16 is provided after the G-microphone jack 14 to attenuate high-frequency sounds and prevent howling.

However, in the configuration described in -1-, there is a problem that howling occurs when the microphone plug 11 of the high naural hesodophone is connected to a general external microphone input jack. If you connect an input jack from another audio device to a pinaural headphone microphone input jack, there is a problem that the high frequencies will be attenuated. Two input terminals of the external microphone input jack are required, and providing two input jacks is one of the major reasons why headphone audio equipment cannot be miniaturized.
