Description

New bone conduction wearing earplugs

【Technical field】

The invention belongs to the technical field of earphones, in particular to a novel bone conduction wearing earplug.

【Background technique】

Bone conduction is a sound conduction method, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve, and auditory center.

Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can achieve clear sound reproduction in a noisy environment, and the sound waves will not affect others due to diffusion in the air . Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology:

(1) Bone conduction loudspeaker technology is used for receiving speech, listening to sound when receiving speech. Air conduction speakers convert electrical signals into sound waves (vibration signals) and transmit them to the auditory nerve. The bone conduction speaker is that the sound wave (vibration signal) converted from the electrical signal is directly transmitted to the auditory nerve through the bone. The transmission medium of the sound wave (vibration signal) is different.

(2) Bone conduction microphone technology is used to send a call, and the sound is collected when sending a call. Air conduction transmits sound waves through the air to the microphone, while bone conduction transmits them directly through the bones.

Earphones manufactured using these bone conduction technologies are called bone conduction earphones, also known as bone conduction earphones, skinny earphones, bone conduction earphones, and bone sensor earphones.

At present, most bone conduction earphones on the market are worn in the headband style, which bypasses the back of the head and is clamped on the skull near the ears on both sides by two sound-generating units. However, with the development of technology, bone conduction earphones are now also used as hearing aids. Use, after using this wearing method for a long time, it is easy to feel uncomfortable and affect the use.

【Content of invention】

In order to solve the problem that bone conduction earphones are easy to feel uncomfortable in the prior art, the present invention provides a novel bone conduction earplug that is comfortable to wear.
