Description

The present invention relates to a headset for bone conduction, and more particularly, not only prevents the bone conduction portion from migrating from active physical movement and causing pain due to local compression of the bone conduction portion. The present invention relates to a bone conduction headset capable of transmitting the acoustic wave output from the bone conduction portion to the auricular cartilage to greatly improve the listening efficiency of the sound.

Generally, the sound heard by the human ear is transmitted in the form of waves. External sound enters through the human outer ear and vibrates the eardrum, and cells are stimulated and transmitted to the brain in the inner ear inside the eardrum. The frequency range of sounds that humans can hear is about 20 to 20000 Hz, and the frequency range of sounds that humans talk about is about 500 to 2000 Hz.

However, in the case of a deaf person, there is a risk that the sound of all frequencies or a part of the frequency range of the sound cannot be heard. Therefore, recently, a bone conduction method that transmits sound through the vibration of the skull has been used.

The bone conduction method is a method in which the sound of vibrating the skull is transmitted to the cochlear shell and transmitted to the brain via the auditory nerve. Since the bones around the ears are vibrated to transmit sound, it can be effectively used not only by people with hearing impairments but also by people who work in places with heavy noise.

On the other hand, the conventional first bone conduction type headset (Patent Document 1) merely provides a function for improving the output of the bone conduction portion that transmits sound, so that when the user exercises violently. There is the inconvenience that the slip-off phenomenon occurs when there is irregular movement and the position of the bone conduction headset must be corrected frequently. There was the inconvenience of causing headaches by continuously applying pressure.

In addition, the conventional second bone conduction type headset (Patent Document 2) can improve the adhesion between the user and the bone conduction speaker and suppress the cause of pain in the temple area of the user. As described above, a technique is disclosed in which a length adjusting portion and an angle adjusting portion are configured for each of the head stationary portion and the earband portion.

However, the conventional second bone conduction type headset can adjust the width of the earband according to the size of the head image to reduce the pain to the temples of the user, but when exercising. There is an inconvenience that the phenomenon that the speaker floats due to irregular movement still occurs.

In addition, the conventional first and second bone conduction type headsets have a limit in improving listening efficiency because the bone conduction speaker transmits sound through the user's side bone, that is, the temple. Not only was there a drawback, but the bone conduction section located in front of the user's ear did not look good.
