Bone Conduction Headphone

Welcome to the world of audio innovation, where sound takes on a whole new dimension. Robotshapers proudly presents Bone Conduction Headphones, the revolutionary audio devices that transcend traditional boundaries. Say goodbye to conventional earphones and immerse yourself in a captivating audio experience like never before.

Bone Conduction Headphones are audio devices that transmit sound through the skull instead of the ear. Here are some details about bone conduction headphones:

  1. How it works: Bone conduction headphones work by vibrating sound waves from the skull bones (mostly cheekbones and temples). The vibrations pass through the outer and middle ear and directly stimulate the inner ear, allowing the user to perceive the sound.
  2. Design: Bone conduction headphones usually include a transducer or transducer pad that rests on the cheekbone in front of the ear. These sensors convert sound signals into vibrations transmitted through bones.
  3. Open Design: The earplugs have an open design which means they do not cover or block the ear. This allows users to be aware of their surroundings while listening to audio, making it popular for outdoor activities or situations where situational awareness is required.
  4. Accessible Hearing: Bone conduction headphones can be beneficial for people with certain types of hearing loss or conditions such as hearing loss, language or deafness alone. Since sound passes through the outer and middle ear, it can also be seen through the inner ear, allowing people with some hearing loss to enjoy the sound.
  5. Sound quality: The sound quality of bone conduction headphones will not be the same as normal headphones, which send sound directly into the ear canal. While bone conduction headphones can provide clear sound, vibrations transmitted through bones can cause the sound to sound slightly different from headphones.

Applications:

Bone conduction headphones are widely used in many fields due to their different functions and qualities. Some important uses are:

  1. Sports and Fitness: Skull is popular with athletes and fitness enthusiasts. 
  2. Deafness: Bone marrow can be beneficial for people with some form of hearing loss or disease.
  3. Safety: In an environment where critical situations are controlled, such as construction sites or factories, caps improve safety and communication by allowing workers to receive instructions or warnings without covering their ears.
  4. Underwater activities: Headphones designed for use in water, suitable for swimmers or people who do water sports. 
  5. Army and Law Enforcement: Bones used for skulls find use in military and law enforcement settings that manage critical situations.
  6. Treatment and rehabilitation: It is used in therapy for ear bone, hearing assessment, sound therapy and target therapy. 
  7. Assistive Technology: The skull can be incorporated into assistive technology for use by people with hearing or communication needs. 
  8. Outdoor activities: bone earplugs are designed for people who enjoy outdoor activities such as hiking, cycling and rock climbing.
