A flat-panel bone conduction earphone with adjustable receiving position

Abstract

The invention relates to a flat-plate bone conduction earphone with an adjustable sound-receiving part, which includes a main bracket, two angle adjustment structures and two sounding units based on a flat-plate vibration unit, wherein the sounding unit is connected to the main bracket through the angle adjustment structure, The cross-shaped chute on the main bracket, the connecting piece in the rotating groove and the angle adjustment structure, and the elastic bracket realize the diverse adjustment of the position of the sound unit. Fit the position to avoid head hair, ornaments or glasses brackets from interfering with the wearing and sound collection of bone conduction headphones, and improve the listening effect of bone conduction headphones.

Description

technical field [0001] The invention relates to the field of bone conduction earphones, in particular to a plate-type bone conduction earphone with an adjustable sound receiving part. Background technique [0002] Bone conduction is a way for people to receive sound signals. Sound transmits and receives sound signals through the human skull, bone labyrinth, inner ear lymph, screw, auditory nerve, and auditory center. The ear method saves the transmission of sound in the air, so that the sound signal can be clearly restored in a noisy background environment. [0003] Bone conduction earphones are earphones designed and manufactured using bone conduction technology. They are often used in the field of hearing aids, sports earphones, and special earphones for military and police due to their special sound conduction and usage methods. They have the advantages of less distortion, liberating both ears, and easy wearing. . [0004] The sound transmission effect of bone conductio...

AI Technical Summary

Problems solved by technology

[0004] The sound transmission effect of bone conduction earphones depends on the good close fit between the sound unit and the user's head. However, the existing bone conduction earphones are limited to the ear-mounted wearing method, and the interaction position between the sound unit and the user cannot be adjusted. , so that the fit between the sound unit and the user's head is limited. For example, a user wearing glasses cannot comfortably and tightly hang the earphone holder due to the restriction of the glasses holder, and a user with thick sideburns cannot because of the restriction of hair. Ensure a good and tight fit between the sounding unit and the head. Users who wear accessories on the head need to change the position where the sounding unit fits the face due to the limitation of the jewelry

That is, the existing bone conduction earphones cannot change the wearing posture of the earphones and the interaction position between the sound unit and the user, thereby reducing the user's wearing and listening experience of the bone conduction earphones

[0005] In addition, the existing bone conduction earphones are based on the dynamic speaker structure, and the movement of the energized coil in the magnetic field directly drives the external structure to apply vibration to the user's skull, which is limited by the power output capability of the dynamic coil and the input of the human bone to the vibration excitation. Requirements, its high-frequency vibration frequency is limited, and the subwoofer performance is insufficient
