4-102+44-S2L : Big switch PTT with ear vibration
Fit for Maxon Midland SP120 SP340 (S2L Plug)
The mechanism works as follows:
Mechanical vibration from earbone => electric signal => transmitted to radio transceiver
Since the speaker/mic is hidden in your ear canal, it is not sensitive to any background noise. This is exceptionally ideal for usage in high ambient environment such as driving, riding motorcycles and bicycles.
Without a separate microphone that could be easily detected by people around you, this is also ideal for surveillance purposes and security at airports, casinos, crowd control at conventions and concerts, and other working environment requiring discreet communications.
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.
Include BIG PTT switch , For radios it can easy work in PTT mode.
The plug leading to the two-way radio is also detachable. It is to be connected by a 6-pin mini din plug. The packages comes with the two-way radio plug for the specified models (see specifications on the left). If you would like to work with radios with different accessory jacks, just come and purchase the suitable cables and plug into your throat mic.
