スピーカと組合せることが可能である。Vibration pickup type ear microphones (hereinafter referred to as ear microphones) are worn in one ear canal and pick up bone conduction sound signals (vibrations) of the wearer that are transmitted to the wall of the ear canal, and are already known. This ear microphone can be combined with an earphone type speaker such as a normal sound pressure type earphone.

ウリング現象が生じる場合があることが判った。Therefore, the present inventors used an ear microphone as a transmitting system and an earphone type speaker as a receiving system.
Regarding the receiving system, we attempted to transmit and receive data to and from the outside using a wireless system. In other words, connect the lead wire that takes out the ear microphone's output to a normal radio (such as a two-way radio), and connect the earphone type speaker cord to the same radio! l
I also put on a powerful ear microphone. As a result, we were able to communicate wirelessly both in transmission and reception. However, not only does the ear microphone become heavier due to the weight of the speaker, making it less comfortable to wear, but also because the ear microphone is a vibration pickup type, so the ear microphone that hangs from the earphone type speaker. The problem was that the ear microphone made a lot of noise from the lead wire of the earphones and the electrical cord of the earphones. In other words, it was found that code noise was transmitted wirelessly, making the transmitted voice unclear. In addition, the "ear microphone lead wire" and "earphone electrical cord" directly connect the "ear microphone with earphone" attached to the ear canal and the wireless device attached to the waist etc. It has been found that when cords increase the output of a wearable phone-type speaker, the ear microphone picks up the output from the speaker, causing a howling phenomenon.
