Background

Bone conduction is different from the traditional air conduction hearing mode, and the special hearing unit (bone conduction loudspeaker) is used for realizing vibration and transmission of sound in the skull and the ear bone of a human body, so that the auditory nerve finally receives sound information and finishes the hearing process. The bone conduction is a special listening mode, an air environment is not needed any more, and air conduction sound is not needed, so that sound transmission is more convenient and smooth, interference to surrounding environment sound is reduced, and listening in a special environment (such as underwater) is possible. For persons with impaired eardrum, blocked auditory canal, bone conduction can effectively wake up their auditory function.

One application of the bone conduction technology is a bone conduction Bluetooth headset, which is generally a headset, and is gradually accepted and favored by sports lovers such as body building, riding, running and the like because the headset has the advantages of safety, comfort, health, sanitation and the like.

In a conventional bone conduction headset, two bone conduction speakers (one for each of the left and right cases) are generally configured, and the quality of the bone conduction speakers determines the expressive power of the headset audio. The structure and the material of the bone conduction speaker are limited, and the low-frequency sound effect deviation is lower than that of the air conduction speaker in the expressive force of music. In order to solve the problem, in the prior art, in the design configuration of the speaker, a single bone conduction speaker in a housing is changed into a "dual speaker structure" of a bone conduction speaker and a gas conduction speaker, and the design can make up for the defect of insufficient bass effect, but some problems are newly added: the air guide loudspeaker is added, so that the power consumption of the earphone is obviously increased, the effective service time of the earphone is ensured to adapt to large power consumption, the battery capacity is required to be increased, the weight of the battery is correspondingly increased, and the cost is also increased; the air guide loudspeaker is added, so that the weight of the earphone and the volume of the wearing shell can be correspondingly increased, the appearance and the wearing comfort of the earphone are greatly reduced, and the requirements of modern wearing of the earphone for light weight are not met.
