骨传导耳机介绍[新版] We "use ears for listening" when talking to someone or listening to music. However, this seemingly natural perception is not accurate. Whales living in the ocean have ears inside their bodies where seawater and hydraulic pressures have no effect. Their ears are structured so as to block direct external sounds. In spite of that, whales hear sounds just like other animals. Ludwig van Beethoven became hard of hearing late in life, but the great composer listened to the piano in a way that allowed him to continue writing music. How do whales catch sounds? How did Beethoven listen to music? Whales use the lower jawbone to catch vibrations that travel through water and transmit them to their ears. Beethoven held a baton between his teeth and pressed it tightly against his piano. He listened by transmitting the piano sound vibrations from his teeth to his hearing organs by way of his skull. As these examples show, there are two transmission routes for sounds and voices: the air and bones. Vibrations that reach our ears through the air are known as air-transmitted sound. People normally refer to these vibrations when discussing hearing. Vibrations that reach our ears through bones are called bone-transmitted sound. Thus, sounds and voices reach our ears as vibrations through the air or through our bones and skin. As explained above, vibrations or what we conceive as sounds reach our ears (1) through the air or (2) through our bones and skin. The auditory nerve in our inner ear detects both types of vibratory motion as sound immediately upon arrival. We would like to explain how these vibrations or sounds travel to the auditory nerve as follows: Let us begin our explanation with air-transmitted sound. We normally "hear sounds with our own ears" when detecting vibrations in the air. Human speech, radio, and television sounds vibrate the surrounding air. The outer ear collects and guides these vibrations into our external auditory canal. Vibrations reach and shake the eardrum through the external auditory canal. Our middle ear amplifies this vibratory motion, which we perceive as sounds the moment it swings the tip of our auditory nerve floating in lymph that fills the cochlear canal in the inner ear. Bone-transmitted sound refers to "directly transmitted vibrations." These vibrations do not bypass either the outer ear or middle ear, and travel straight to the cochlear canal in the inner ear. Upon arriving in the cochlear canal, this vibratory motion shakes the auditory nerve floating in lymph. We can still hear our own voice when speaking with our ears covered. We can do this because our bones and skin transmit the vibrations of our speech. Our own voice sounds like someone else's when we utter words with ears covered. We sense this impression because closed ears shut out air-transmitted sound. We receive most vibrations from our bones and skin when covering our ears. Our own voice sounds strange when speaking with our ears covered because the voice we always hear and recognize as our own is a mixture of air-transmitted and bone-transmitted sound. Hearing through the bones and skin offers many advantages because it does not require you to lend your ear to air-transmitted sound. The greatest advantage is complete freedom in both ears. You can catch sounds in your surroundings and have natural conversations without disconnecting your bone conduction speakers. You can use earplugs in combination to protect your hearing against loud noise. Bone conduction speakers serve various occasions and demands. You can use them in water and other special environments. Though we produce our voice by vibrating the vocal cords, other people catch our vibrations released in the air with their ears. That's how others perceive our voice. The vibratory motion of the vocal cords travels to our own hearing organs through two transmission routes: the air and our skull. We can hear our own voice when covering our mouth or ears with our hands, then saying something. We can catch our voice in such experiments thanks to bone conduction. However, our own voice sounds different from our normal one when speaking with covered mouth or ears. We experience this change because we only catch bone-transmitted sound under such circumstances. The opposite also holds true. Our own voice sounds strange when taping it and playing it back because a tape recorder only catches air-transmitted sound. Our bones transmit voices. We can hear through our bones by using a highly sensitive vibration sensor to collect the vibrations of the vocal cords (that vibrate the bones) and converting these vibrations into electric audio signals. 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. 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. We have developed communications tools that provide high added values in various fields by applying the bone conduction mechanism to a broad range of cutting-edge telecommunications technology. Our achievements include hands-free communications systems for various uses (listening-only and two-way models), a bone conduction hearing aid incorporating a bone conduction speaker (Kikuchan), and a helmet-type communications system (Shellshocker).

In addition to such unique way with our bone conduction products, utterly new "STICKER" type headset that sticks to the skin by way of double faced adhesive tape was devised. Adhesive used is of medical grade to guard against skin irritation. 2) Excellent noise tolerance Sticker type bone conduction microphone placed close to the throat provides direct pick up of strong vocal chords vibration or the voice itself (in such case, not a bone conduction in a strict sense), and as a result, its level of noise tolerance is far more greater than that offered by bone conduction microphone placed in the ear or on top of the skull. Sticker type microphone need not be constantly pressed against the throat (simply attached with adhesive tape) thus it allows long hour usage without causing discomfort to the user. 3) Can be used by itself SK1 can be used in combination with most types of helmet or facial mask. Also, since the headset operates on its own, continued communication is possible with helmet removed during the break for example. 4) Comes in two different style SK1 is placed behind the lower portion of the ear and diagonally toward the throat.

If any of the following applies to you, KIKUCHAN can help! *You need to turn the volume up on Television. *You speak too loud or often ask person to repeat what he/she has just said. *Dislike hearing aid because it covers your ears, and not interested because it increases the volume of unwanted noise as well. *Cable attachment is too cumbersome. *Have trouble hearing the perso n's speech at a meeting or lecture. 1)Amplifier with distinctive feature of the bone conduction Unlike conventional hearing aid or amplifier, we devised the amplifier based on the mechanism of bone conduction. Our proprietary bone conduction amplifier converts sound signal from television and microphone into vibration and send it directly to the auditory organ via bone conduction speaker (patented). Kikuchan offers many advantages including clear and noiseless sound and user comfort due to no device over both ears. 2)Easy to use wireless bone conduction amplifier The device uses wireless infrared system, so there is no cable. It provides freedom of movement, and sound of the television could be clearly heard from every corner of the room. Tone quality is as soft as " Bone Conduction Assistive Listening Device KIKUCHAN " . 3)Simple installation and easy operation Device is installed simply by connecting the infrared transmission unit to the output jack of the television. Sound signal from the infrared unit is received by a mobile unit, and then transmitted to the auditory organ via bone conduction speaker. Since it does not cover either ear, normal conversation is possible. 4)Useful at a meeting or lecture This device can be used by any number of people corresponding to the number of mobile Unit + Headset. Combined use of the microphone within the infrared transmission unit with external microphone will prove very useful in the setting of a meeting or lecture for example. 5)Does not affect high tech electronics equipment Infrared wireless device emits no electromagnetic wave so it is safe on human as well as on various high tech equipments. Needless to say, there is no need to apply for the license issued under Wireless Telegraphy Act. 6)Built in rechargeable lithium ion battery Single charging of the lithium ion battery yield approximately ten hour operation. *Battery life differs according to the mode of usage. The amplifier is usable during battery charging.
