Description

a vibrating horn

technical field

The utility model relates to the technical field of vibrating horns, in particular to a vibrating horn.

Background technique

Generally speaking, people can hear the sound can be divided into two types: air conduction and bone conduction. Air conduction is that air transmits vibrations to the eardrum through the external auditory canal, and the vibration formed by the eardrum drives the human auditory nerve, thereby perceiving the vibration of sound. Bone conduction is the conversion of sound into mechanical vibrations of different frequencies. It does not pass through the external auditory canal and eardrum, but is directly transmitted to the inner ear through the vibration of skin tissue and bones to drive the human auditory nerve. The tract, inner ear lymph, auger, auditory nerve and auditory center to transmit sound waves. Headphones made by using the principle of bone conduction are called bone conduction headphones. The core components of bone conduction headphones are bone conduction vibration speakers, which are called vibration speakers. The vibration speakers belong to the electromagnetic conversion unit without vibration membrane. Relatively narrow, poor sensitivity, and unsatisfactory sound quality. If the sensitivity and sound quality are improved, the speaker will transmit sound relative to the surrounding air at the same time. At this time, the speaker has serious sound leakage and large vibration, causing discomfort to the user and high power consumption. , so far no effective solution has been proposed.
