Bone conduction communication device waterproof and noise suppression functions

It has waterproof and noise suppression functions. The bone conduction headphones utilize the bone vibration sensing technology. While the user is receiving wireless signals, they can also keep their ears independent and clearly receive other sounds from the surrounding environment. The principle is to complete radio transmission through sensors, that is, by sensing the vibration of the facial bones and converting the signal, and then receiving the signal through the inner ear canal. Additionally, the suspension structure of some helmets has low elasticity and strong rigidity, and is incompatible with headphones with vertical frame designs. However, bone conduction headphones can take advantage of the design of their horizontal frame (surrounding the back of the head) to eliminate this discomfort and can be worn simultaneously with helmets and hearing protection equipment.
II. Product Features
1. Full bone conduction: Bone conduction speaker + bone conduction microphone, both transmission and reception are bone conduction.
2. Communication type: Environmental hearing communicates through external two-way radio.
3. Low sound distortion, high fidelity, in a 110DB background noise environment, the delivered speech can be accurately transmitted at more than 95%.
4. Easy maintenance: The left and right bone conduction can be replaced with fireproof silicone ear pads.
5. Cable self-release design: The connecting cable uses a Φ4.2mm black spiral stretchable cable, and the connecting plug uses a 7-core safety self-release device, which can ensure quick disconnection in emergency situations and ensure the safety of the user.
6. Ergonomic design: The fixed steel card can be freely adjusted, the top headband can be freely adjusted, to adapt to the differences in head shapes of different users; The bone conduction speaker uses the natural tension of the spring to closely fit the facial bones while ensuring comfort, reliability, and long-term wearing, and does not affect the use of helmets, air respirators, gas masks, and other protective equipment.
7. To ensure the comfort of long-term wearing in terms of weight, the bone conduction part weighs 125±3 grams, and the PTT control box part weighs 150±3 grams.
8. Speech and listening do not use air as a transmission medium, ensuring clear communication in high-noise environments, with low leakage when listening, and having good confidentiality.
9. Both ears are open, wearing does not affect the user’s listening to the sounds of the surrounding environment.
