Bone conduction headphones are headphones that transmit sound vibrations to the ear through bone conduction technology. Traditional headphones need to be inserted into the ear to transmit sound signals from the microphone to the ear, while bone conduction headphones use bone vibrations to transmit sound signals directly to the ear.
Bone conduction headphones work by converting sound signals into vibration signals, which are then transmitted through the bones to the inner ear, allowing people to hear sounds. This way is different from the traditional way of transmitting sound through the ear canal, so it can avoid damage to the ear canal and eardrum caused by traditional headphones.
The structure of bone conduction earphone mainly includes the following parts:
1. Vibrator: Vibrator is the core component of bone conduction headphones, which converts sound signals into vibration signals and then transmits them through the bone to the inner ear. Vibrators are usually made of piezoelectric ceramic materials, which have good vibration properties and durability.
2. Skeleton: The skeleton is the support structure of the bone-conducting headset, which holds the vibrator to the ear and provides a comfortable wearing experience. The skeleton is usually made of lightweight materials, such as titanium or aluminum alloy, to reduce the weight of the headset.
3. Microphone: The microphone is another important part of the bone conduction headset, which is used to collect the sound signal and pass it to the vibrator. Microphones usually use noise cancellation technology to improve the clarity and quality of sound.
4. Battery: The battery is the power source of the bone-conducting headset, which provides power to the vibrator and microphone. Batteries are usually rechargeable lithium-ion batteries or polymer batteries to provide a long battery life.
5. Control button: The control button is the control panel of the bone conduction headset, which is used to adjust the volume, switch songs, answer the phone and other functions. The control buttons are usually designed by touch or touch-tone to facilitate user operation.
6. Audio interface: The audio interface is the audio output interface of the bone conduction headset, which is used to connect the headset cable or Bluetooth device. The audio interface is usually 3.5mm or Type-C interface to facilitate users to connect different devices.
The advantages of bone conduction headphones include hygiene, comfort, relative safety and health, but the disadvantages are relatively poor sound quality and sound leakage. When choosing bone conduction headphones, pay attention to wearing comfort, waterproof ability, sound quality, stability and endurance. Recommended bone-conduction headsets on the market include runnerpro3, as800, Philips A8606, and runnercc2.
