Yes, bone conduction is used in smartphones. A very successful mobile company Kyocera developed a new phone which enables bone conduction feature. The most current Kyocera’s cell phone having an outstanding feature that you don’t see a lot of. The Kyocera Urbano Progresso uses the bones in your mind rather than a speaker to deliver sound to your ear.
The sound you hearing all the day is clearly transmitted to you through the air by sound waves. However, you additionally experience bone conduction. When you communicate with another person, so your own voice is transmitted through the skull as vibrations.
If you need more information or you have a question regarding Bone Conduction, you can discuss it with our HearingSol healthcare professionals, just give us a call on +91-9899437202. We are always here to help you.
Since bone is impressively thicker than air, your voice sounds lower to you. Ever hear your own voice. It most likely sounds higher than you hear it in your mind.
The smartphones that use bone conduction need to account for the frequency shift to avoid distortion.
How does it work?
A gadget that utilizes bone conduction sound is basically bypassing the eardrum. It is your eardrum (or tympanic layer) in the center ear that concentrates sound waves down into vibrations that can be distinguished by the cochlea in the inner ear. Bone conduction vibration waves essentially influence the internal ear straightforwardly. To consider it another way: a bone conduction transducer work as your eardrum.
Technology (Bone Conduction)
The innovation has given us numerous boons, for example, bone conduction is one of them. It is the medicinal hearing device valuable for the general population experiencing hearing loss. It consists of a little titanium which is properly fitted. Bone conduction transmits sounds by direct conduction through facial bones.
Bone conduction system helps in sound transmission as vibration to the inward ear pass through the middle ear. At the season of either recording or playback, distinctive sounds show up in one’s ears.
There is also a couple of clear advantage. In any chance that you’ve at any point been in a noisy room trying to accept a call, you know how disappointing it can be as you press the speaker increasingly hard to your ear with expectations of shutting out a few of the background noise. With bone conduction, the sound passes appropriate from the transducer to your inward ear making it less difficult to hear the other person voice.
Reportedly the sound on this smartphone quite good, and it is the first smartphone get this technology.
One of the greatest disadvantages of getting bone conduction technology in smartphones has been the power requirement. It more often than not takes more energy to output enough as vibrations match with the volume you would get over the air. Kyocera claims to find the solution to this issue with its restrictive Smart Sonic technology.
A major problem with bone conduction has always been the quality of the sound. Because of the nature of the bones making up your skull, stereo sound is muddy and harder to keep straight.
