China Manual Head-Mounted Bone Conduction Communication Device

Manual head-mounted bone conduction communication device (H2M1)The head-mounted bone conduction communication headset is a small and light communication unit specially designed for extremely dangerous environments. It is easy to use and can be worn alone;
Use a high-sensitivity vibration sensor to collect the vocal cord vibration transmitted to the skull and convert the vibration signal into a sound signal; unlike other traditional headphones, a thin waterproof bone conduction vibration sensor is placed on your head;
The PTT control button converts the vibration signal of the pickup into an ordinary audio signal. After noise filtering, it is amplified to a signal that can be matched by the intercom, and then transmitted to the intercom.
The ultra-large button structure design allows even thick gloves or heavy protective clothing (firefighters) to be easily activated.
Polycarbonate material strengthens the solid performance of the shell, built-in positive and negative air pressure adjustment device, precise scientific waterproof, mechanical structure design, can withstand extreme water pressure and impact.
