Description

Novel bone conduction loudspeaker of structure

Technical Field

The utility model relates to a hearing aid equipment technical field specifically is a novel osteoacusis loudspeaker of structure.

Background

Generally, a person can hear sounds divided into two types: air conduction and bone conduction. Air conduction is the vibration of air that transmits vibration to the eardrum through the external auditory meatus, and the vibration formed through the eardrum drives the human auditory nerve, thereby sensing sound. Bone conduction is to convert sound into mechanical vibration of different frequencies, which is directly transmitted to the inner ear through vibration of skin tissues and bones without passing through the external auditory canal and the eardrum to drive the auditory nerve of a human, specifically, the sound wave is transmitted through the skull, the bone labyrinth, the lymph fluid of the inner ear, the spiral organ, the auditory nerve and the auditory center of the human. The earphone is made by utilizing the bone conduction principle and is called as a bone conduction earphone, the core component of the bone conduction earphone is a bone conduction vibration loudspeaker, also called as a bone conduction loudspeaker, a certain problem still exists when the existing bone conduction loudspeaker is used, the existing bone conduction loudspeaker generally depends on artificial adhesion to install each element in the shell, great trouble and time waste are caused during installation, and the situation that viscosity is reduced is easily caused by glue for a long time.
