Description

Safety helmet with bone conduction communication {SAFETY HELMET WITH THE BONE-CONDUCTION RECEIVER}

The present invention relates to a helmet capable of bone conduction communication, more specifically, the user wearing the helmet to deliver the sound through the bone conduction speaker mounted on the inside of the helmet without incorporating the earphone speaker into the ear to adhere to the scalp It is characterized by the ability to hear.

In recent years, wireless communication equipment has been rapidly developed to enable communication without regard to the distance between people who want to communicate.

In this case, a microphone for converting a word coming through the mouth into an electric signal and a speaker for emitting an electric signal transmitted from the wireless communication device as sound is required.

In addition, since the sound coming from a normal speaker cannot be mixed well with the surrounding noise at places near the road, in the field, or at construction sites, earphones (or headphones, etc.) can be distinguished from the surrounding noise. Add and use the attached equipment.

On the other hand, people who work at construction sites often use the above communication equipment as well as wearing a hard hat for the safety of the body bar, earphones (or Headphones) Assemblies are often equipped with hard hats.

In this case, after wearing the hard hat on the head, the earphone connected to the inside of the ear to hear the sound transmitted to the communication equipment, there is the following problems in the conventional hard hat as described above.

In other words, when the earphone is inserted into the ear, there is no problem in communication through the communication equipment, but during that time, it is exposed to an insecure state because it can hardly or indirectly hear the direct sound from the surroundings of the site.

In addition, when communicating frequently using communication equipment, it is cumbersome to remove and insert earphones, and it is cumbersome to remove and insert earphones more often. At this time, there is a lot of concern about safety accidents because they are still in an unsafe state for the surrounding sounds.

In particular, when the noise of the workplace is damaging to the ear, the earplugs must be worn and work on the work.In order to communicate, the earplugs must be removed and the earphones must be inserted. It is damaging.

Therefore, the present invention has been made in view of the conventional problems as described above, the main object of the present invention is to provide a helmet with a bone conduction speaker and a bone conduction microphone attached to the inside, to go out to wear a hard hat The objective is to prevent safety accidents and to communicate in a noisy environment without using conventional earphones.

A characteristic means of the present invention for achieving the above object is a bone conduction microphone fixed to the front inner circumference of the helmet, in a conventional hard hat provided with a cushioning member and a cushioning belt, and a binding band on the hemispherical inner circumference; A microphone / speaker assembly comprising a bone conduction speaker fixed to an inner circumferential surface and a cable connecting them is provided and configured.

Hereinafter, the detailed configuration and operation of the present invention will be described with reference to the accompanying drawings.

1 is an exploded perspective view showing the overall configuration of the present invention, Figure 2 is an enlarged view showing a microphone / speaker assembly using bone conduction.

For reference, bone conduction is a phenomenon in which sound waves are transmitted to the skull and transmitted directly to the inner ear. The pure bone conduction when the skull directly enters the inner ear, and the skull are transmitted to the three osseous bones and then transferred to the inner ear. There is a bone solid conduction (骨 鼓室 傳導).

And bone conduction microphones and bone conduction speakers refer to the means for communication using this phenomenon.

As shown in the drawings, the hard hat 10 of the present invention is a conventional hard hat provided with a cushion member 12, a cushioning belt 13, and a head binding band 14 on an inner circumferential surface 11 therein.

At this time, the present invention is provided with a microphone / speaker assembly (20) consisting of a bone conduction microphone (21) fixed to the front of the hard hat, a bone conduction speaker (22) fixed to the side inner peripheral surface and a cable (23) connecting them. Is characteristic.

In particular, since the bone conduction microphone 21 should be in contact with the epidermis of the forehead, the bone conduction speaker 22 should be embedded in the endothelium 15 of the head binding band 14, and the bone conduction speaker 22 should be in contact with both left and right temples of the forehead. Therefore, the mold member 40 is directly attached to the inner circumferential surface 11 of the hard hat 10.

On the other hand, the microphone / speaker assembly 20 of the present invention has a connection jack 23a at the end of the cable 23 can be connected to the flexible extension cable 30 which can be connected to the wireless communication terminal 50. It is supposed to be.

In addition, the microphone / speaker assembly 20 described above may use a conventional speaker having a normal speaker 24 at the end of the cable 23 as shown in FIG.

And the mold member 40, as shown in Figure 4 in order to intermittently secure the cable 23 to the inner peripheral surface of the hard hat is provided with a hook 41, the back side uses an adhesive layer 42 is provided, Such a mold member may not necessarily be represented in the drawings, but may use any other embodiment means capable of intermittently fixing the cable.

In the drawing, reference numeral 25 is a clip.

The helmet 10 according to the present invention configured as described above communicates by turning on the terminal in the state instead of inserting a separate earphone when a signal received from the wireless communication terminal 50 is received while wearing the helmet.

That is, when the terminal 50 is turned on, since the bone conduction speaker 22 is in contact with the temple of the wearer of the helmet, the skull is directly delivered to the inner ear, or the skull is delivered to the three osseous bones, and the osseous bone is then delivered to the inner ear.

In addition, the bone conduction microphone 21 in contact with the forehead senses vibration generated through the skull when the wearer of the hard hat speaks, and the terminal converts it into radio waves and transmits it to the communication means.

As described in detail above, the present invention provides a microphone / speaker assembly having a bone conduction speaker and a bone conduction microphone inside the hard hat, so even in a noisy environment, communication is performed using bone conduction without using a conventional earphone. This will be possible.

Therefore, it is not necessary to repeat wearing and removing earphones while wearing a hard hat, and since the ear is not normally blocked, it is possible to immediately respond to the sound of the field, thereby preventing safety accidents.

In addition, in the case of industrial sites where the earplugs must be worn due to noise, communication can be performed without removing the earplugs, thereby protecting the ears and preventing safety accidents due to communication failures.
