Bone conduction microphone, as an emerging microphone, is based on the principle of transmitting sound waves directly to the bone, and then from the bone to the hair cells in the ear, rather than through the air. Compared with traditional microphones, bone conduction microphones have many advantages. Firstly, it is more natural to use. While traditional microphones need to pick up and transmit sound through the ear or mouth, bone conduction microphones do not need to do so, and only need to transmit sound through the bone, which is more comfortable and natural to use. Secondly, it is more stable and reliable. Because the bone conduction microphone uses the human body's own bones as the transmission channel, so it can avoid the air barrier and interference, improving the stability and reliability of sound transmission. In addition, bone conduction microphone also has a certain degree of waterproof and dustproof ability, can to a certain extent adapt to a variety of harsh environments.
However, bone conduction microphone also has some disadvantages. Firstly, its sound quality is relatively poor. Since the sound needs to be transmitted through the bone, it will lose part of the high frequency and low frequency sound, resulting in the sound quality is not as good as the traditional microphone. Secondly, it has a limited range of use. Since a bone conduction microphone requires direct contact with the bones of the human body, it may not be able to be used in some special occasions, such as swimming and diving. In addition, it is relatively expensive. Since bone conduction microphone requires high manufacturing process and technology, its price is relatively high and may not be suitable for everyone.
In summary, a bone conduction microphone has many advantages over a conventional microphone, such as a more natural way of use, greater stability and reliability, and a certain degree of waterproof and dustproof capability. However, it also has some disadvantages, such as relatively poor sound quality, limited use, relatively high price, etc.. In practical application, it is necessary to choose the appropriate microphone according to the specific needs and occasions.
