Professional Ear-Vibration 2-in-1 Speaker/Mic for Yaesu
This new Ear-Vibration 2-in-1 Speaker/Mic is designed for professional use. The performance of this new model is greatly improved comparing to the ordinary Ear-vibration 2-in-1 Speaker/Mic.
Apart from being a headphone, the earpiece also translates the vibration of your earbone into an electric signal and transmits it through your transceiver to another two-way radio. With this 2-in-1 speaker/mic, you can get rid of a separate microphone.
The mechanism works as follows:
Mechanical vibration from earbone => electric signal => transmitted to radio transceiver
The sensitivity of the newly designed microphone is greatly improved to cover a much wider range of frequency. Graph 1 shows that an ordinary speaker/mic best performs in the range of 1400 to 1800Hz while the newly designed model shown in Graph 2 provides execellent performance in the range of 900 to 3900Hz. With a much more sensitive microphone, transmission becomes clearer and distortion is greatly reduced.
Length of cable: 119 cm / 3'11" from plug to earphone; 116 cm / 3'10" from plug to PTT;
