Finally, you can record your voice the way YOU hear it. BCM's convert vibrations from your head or ears into sound. They can also be used as hearing aides for the deaf and hard of healing. Forget buying expensive musical instruments, create music directly from your mouth the way you hear it when you sing.
Bone conduction speakers offer a technical base for hearing voices and sounds through bones. These devices enable hearing-impaired people to catch sounds when there is no vibration in the air, and operate on the principle that we perceive sounds when vibrations reach our hearing organs directly. Based on this principle, we developed and patented a small, high-output bone conduction speaker that converts audio signals into vibrations. We realized unprecedented user convenience by integrating this speaker in a headset.
Bone conduction microphones form another technical basis. The microphone cords use a highly sensitive vibration sensor to collect vibrations that reach the skull from the vocal cords and convert this vibratory motion into audio signals. You can wear these devices all over your head to pick up vibrations, provided they are mounted on a relatively solid section of your head. We offer two types of bone conduction microphones: an "ear microphone" that picks up vibrations in the auditory canal, and a headset that captures vibrations on the head. We equipped both products with corrective circuits optimized for converting bone-transmitted sound into clear voices. These products are compatible with various types of telecommunications equipment.
Voice transmitted through the bones is the same as converting vocal cord vibrations into audio signals upon reception by the skull. You can catch cranial vibrations or voices in airless environments. Hearing aids incorporating the bone conduction mechanism offer users many advantages. These devices are easy to waterproof (for outdoor and underwater use), offer excellent tolerance to noise (thus less susceptible to external noise) and flexible to wear (by allowing you to position the microphone away from your mouth). You can use hearing aids in many places and on many occasions.
