Description

Bone conduction sound production device

Technical Field

The application relates to the field of portable bluetooth headset, especially, relate to a bone conduction sound generating mechanism.

Background

The earphone is a common article in daily life of people, can better meet the individual hearing requirement, and can not cause interference to the surrounding environment. There are many types of earphones, and common earphones include an earplug type earphone, an earphone type earphone, and a rear-hanging earphone.

Bone conduction is a sound conduction mode, namely, sound is converted into mechanical vibration with different frequencies, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid transmission of the inner ear, the spiral organ, the auditory nerve and the auditory center of a human body. Compared with a classical sound conduction mode of generating sound waves through a vibrating diaphragm, the bone conduction mode omits a plurality of sound wave transmission steps, can realize clear sound restoration in a noisy environment, and does not influence other people due to the fact that the sound waves are diffused in the air. The bone conduction technology is divided into a bone conduction speaker technology and a bone conduction microphone technology:

(1) bone conduction speaker technology is used for speech, i.e. listening to sound. The air conduction speaker converts an electric signal into a sound wave (vibration signal) and transmits the sound wave to an auditory nerve. The bone conduction speaker is a sound wave (vibration signal) converted from an electric signal and directly transmitted to the auditory nerve through the bone. The transmission medium of the acoustic wave (vibration signal) is different.

(2) Bone conduction microphone technology is used for receiving, i.e. collecting, sound. Air conduction is the transmission of sound waves through the air to the microphone, while bone conduction is the transmission directly through the bone.

Headphones manufactured using these bone conduction technologies are called bone conduction headphones, and are also called bone conduction headphones, bone sensing headphones, and bone sensing headphones. The bone conduction earphone receives the telephone by using a bone conduction technology, is tightly attached to the bone, and directly transmits the sound wave to the auditory nerve through the bone. Therefore, the ear drum can be opened without damaging the eardrum, and is also popular among consumers.

Earplug formula earphone possesses good immersive effect, and the user often has good sense of hearing, nevertheless fills in the ear for a long time, both causes the injury to the ear, also often can let not hear the sound of surrounding environment and cause dangerous the emergence, and bone conduction earphone then compares and possesses better security performance, but the sense of hearing effect probably does not have earplug formula so good.
