Description
Technical Field
The invention belongs to the field of earphones, and particularly relates to a multi-medium conduction dual-microphone earphone.
Background
With the development of economy, a microphone commonly used by people is air conduction, which is called an air conduction microphone for short, and has the advantages that the energy loss of sound waves in the air is small, and high-quality sound quality can be obtained, but the defect is that other sounds in the air are collected indiscriminately, so that a large amount of noise exists in a noisy environment, and the noise is difficult to filter. Compared with the air conduction microphone, the bone conduction microphone is in contact with the skin, detects mechanical vibration generated by the skull and vocal cords when a user speaks, and converts the mechanical vibration into an audio signal. Compared with an air conduction microphone, the bone conduction microphone can naturally filter noise in the surrounding environment and has strong anti-noise capability. Therefore, the earphone adopting the technology is also applied to special scenes with large noise, such as military affairs, rescue and the like, for example, the earphone based on the bone conduction technology disclosed in the patent CN 204425599.
However, the sound collected by the bone conduction microphone is not optimized by deep processing of the vocal organs such as lips, teeth, tongue, soft palate, hard palate, oral cavity, pharyngeal cavity, nasal cavity and thoracic cavity, so that the sound quality is poor and even the sound quality is difficult to be recognized by the listening party. In addition, when the bone conduction microphone is used, the bone conduction microphone needs to be tightly attached to the skin, so that other clamping structures are needed to fix the bone conduction microphone near the vocal cords or on the head; once the user moves violently, the user can loose the device to make the sound big and small, and clear and fuzzy, which brings inconvenience to the user. The technology is not widely applied for the two reasons, and even in the military field, the technology is only used at special moments or even under the condition of unavailable scenes, so that the effective use time is very short.
