bone conduction microphone is a microphone consisting of a pickup, vibration acquisition component, and noise reduction components with a stable connection and excellent call clarity. In today's communication environment, the use of bone conduction microphones can help users achieve clear sound restoration in noisy environments, especially in scenes with large ambient noise, with good noise reduction effect.
The principle of the bone conduction microphone is to transmit sound through the bone, avoiding the classical sound conduction method of generating sound waves through the diaphragm, thus reducing many of the steps of sound wave transmission. Its open sound transmission structure helps to keep the ear canal clean, but it also has the disadvantages of small volume, narrow frequency domain, high distortion, low frequency attenuation, and high cost.
The pickup of a bone conduction microphone is usually composed of an elastic material that covers all sides of the pickup other than the pickup surface and is provided with an opening corresponding to one end of the pickup surface. The role of the pickup is to convert sound into an electrical signal and transmit it to the vibration acquisition component.
The vibration acquisition component is the core part of the bone conduction microphone, which converts the electrical signal from the pickup into mechanical vibration and transmits it to the noise reduction component. The role of the noise reduction component is to convert the mechanical vibration into an electrical signal and transmit it to the output of the microphone.
The advantage of bone conduction microphone is that it can achieve clear sound restoration in noisy environments, especially in scenes with large environmental noise, and has a good noise reduction effect. In addition, it also has the advantages of comfort, safety and ear protection.
However, bone conduction microphones also have some disadvantages, such as low volume, narrow frequency domain, high distortion, low frequency attenuation, and high cost. In addition, since the pickup and vibration acquisition components of the bone conduction microphone need to be in contact with the bones of the human body, attention needs to be paid to hygiene and comfort during use.
In general, bone conduction microphone is a microphone with unique advantages and disadvantages, and its application scenario is mainly to achieve clear sound restoration in a noisy environment, especially in the scene of large environmental noise, with a good noise reduction effect.
