China Ear Bone Conduction Communication System

Ear Bone Conduction Communication System(E0M1)
1. Overview
1.1 Function Introduction
The ear bone conduction communication system uses a high-sensitivity vibration sensor to collect the vocal cord vibration transmitted to the ear canal and convert it into a sound signal; unlike other traditional headphones, this product integrates a microphone and a speaker, and the listening and speaking are integrated;
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.
1.2 Product features
a. Help to improve personal safety;
b. Does not affect the use of masks, face shields, helmets and other protective equipment;
c. In a noisy environment, you can still speak and listen very clearly;
d. Waterproof, temperature resistant, acid and alkali resistant, suitable for police, special police, firefighting, and those who need to wear protective equipment such as gas masks, and can also be used for sports enthusiasts such as motorcycles, bicycles, and mountaineering.

4. Component introduction
4.1 Ear bone conduction headphones
This product uses a high-sensitivity vibration sensor to collect the vocal cord vibration transmitted to the ear canal and convert it into a sound signal. Unlike other traditional headphones, E0 integrates a microphone and a speaker, and the listening and speaking are integrated.
Bone conduction earphone shell: send and receive sound signals;
Collar clip: prevent the earphone from being pulled off by external force;
Connector: Connect the PTT control button.
Connector: connect with bone conduction earphone;
Manual PTT button: You can use this button to activate the walkie-talkie. The solid shell structure, precise and scientific protection design can withstand extreme water pressure and impact
5. Install and use
1. Connect the connector of the bone conduction headset to the PTT control
The connector socket of the button;
2. Connect the PTT control button to the intercom;
3. Carefully put the earphone microphone into the ear, as shown in the picture;

4. Shake the earphones slightly to make them firmly occupy the ears
Daoli
5. Bypass the cable of the earphone from above to behind the ear.
The cable sheath of the machine is kept at an angle of about 45 degrees with the horizontal plane
WARNING
Precautions:
a. Before using this communication system, be sure to check whether the intercom can work normally, whether the channel is consistent, etc .;
b. Bone conduction earphones are sensitive components, please do not fold or pinch, and operate carefully.
