Bone Conduction Headphone for Helmet {Bone Conduction Headphone}

The present invention relates to a bone conduction headphone for a helmet, and more particularly, to a bone conduction headphone for a helmet that transmits sound by directly vibrating a bone from the outside without inserting an earphone into the ear.

In general, there are air conduction method and bone conduction method as a way for humans to hear sound.

Among them, the air conduction method is a method in which sound is transmitted through the eardrum to the inner ear, and the vibration of sound transmitted through the air is transmitted to the eardrum and vibrates through three bones located in the eardrum. It is conveyed in this "wow" thing.

Therefore, the cochlea (cochlea) is filled with a liquid called Linbaek, and the vibration of the liquid is converted into an electrical signal and transmitted to the auditory nerve, so that the human brain recognizes sound.

Meanwhile, in the bone conduction method, the sound through the skull (cranial bone) is transmitted to the cochlea and through the auditory nerve to the brain. In the sound recognition mechanism, the process of vibration through the eardrum and three bones located in the eardrum is omitted. I did it.

In other words, the acoustic vibration applied to the skin surface around the ear is directly transmitted to the cochlea through the skull, so even those with hearing impairments with abnormalities in the eardrum or ossicles, if the cochlea and the auditory nerve are normal, bone conduction through the skin is certain. You will be able to hear the sound.

On the other hand, in the case of air-conduction earphones and headphones, the risk of safety accidents increases because you cannot hear noise from the surrounding area by covering your ears. It is legally regulated not to listen to music.

In addition, with the recent remarkable spread of digital sound and communication devices, the increase in noise-induced hearing loss of teenagers worldwide is complaining of hearing loss by more than 10% of the population, and the increase in elderly hearing loss is a social issue even in the global aging era. It is a situation that suggests as an alternative to reduce the time and reduce the use time.

Bone conduction speakers are used with their ears open to receive ambient noise at the same time, thus preventing safety accidents and preventing hearing loss because they are used using the bone conduction principle without directly affecting the eardrum.

Accordingly, in recent years, a lot of techniques for a bone conduction acoustic device that stimulate the auditory nerve through bone conduction by directly vibrating the skull bone to hear sound have been proposed.

Patent No. 10-1561671 "Hairband-type bone conduction sound device" has been disclosed as a prior art relating to bone conduction headphones that an individual wears on their head and transmits sound through bone conduction.

As shown in Patent No. 10-1561671, the bone conduction headphone includes a hook part for hanging on the head, and a bone conduction sound output part provided at both ends of the hook part to apply vibration to the skull to output sound.

These conventional bone conduction headphones are easily peeled off from the head even with a light impact in a way that the hook part is placed in the direction of gravity so as to pass the crown of the head so as to be caught on the head. In order to prevent peeling, the elasticity of the hook portion is also increased, but there is a problem in that the fit is bad and it is difficult to wear for a long time due to the force pressing the skin.

In addition, Patent No. 10-1377418 proposes a bone conduction headphones that can be used by hanging on the ear. Bone conduction headphones worn on the ears have the advantage of not being easily separated or separated from the head even if an accidental impact is applied. However, bone conduction headphones worn on the ears have a problem in that the load of the headphones is concentrated on the ears, causing pain in the ears when worn for a long period of time, and the hook part directly contacts the skin of the neck, causing discomfort for the wearer.

In addition, Patent No. 10-1724063 proposes a detachable helmet bone conduction sound device that is detachable from the helmet surface and vibrates the helmet to hear sound in a bone conduction manner. The bone conduction sound device for a detachable helmet is a structure that is attached to the helmet by a vacuum adsorption method using an adsorption plate, and it is difficult to stably and continuously maintain the adhesive force, and due to this, there is a problem that the sound device may fall off the helmet and be damaged or lost. have. In particular, considering the load of the wind applied while driving the motorcycle, this risk can easily occur.
