Pilot helmet with bone conduction vibrator {THE HELMET FOR PILOT USING A BONE-CONDUCTION DEVICE}

The present invention relates to a pilot helmet using a bone conduction vibrator that transmits and receives accurate information regardless of ambient noise (noise heard through air conduction), which is used when operating aircraft and trams.

The pilot's helmet was equipped with a high-powered speaker that could simultaneously receive noise and control from aircraft and tanks.

Therefore, pilots are required to wear protective plugs in their ears to protect their hearing from high noise (aircraft or tank noise), but do not wear protective caps or listen to them fully with their protective caps for good listening. Aircraft or tanks are often operated in a non-active state, causing hearing loss to the pilots, and inaccurate communication due to noise from the operation of the machine, making it difficult to carry out missions. There has been a problem that psychological anxiety occurs during operation.

Recently, bone conduction vibrators have been used to protect hearing from outside noise and to receive clean sound quality.

Bone conduction vibrator is a device that enables the sound to be transmitted directly to the auditory nerve without going through the eardrum by vibrating the bone surrounding the head instead of listening through the eardrum by the vibration of the air. Even in this severe place, there is a lot of research because there is an advantage that can distinguish the correct voice.

For example, Korean Registered Utility Model Publication No. 20-0282676 has a built-in helmet helmet speech detection device for detecting a voice signal by the vibration generated when the helmet wearer speaks and transmit it wirelessly or wired Is published.

Korean Utility Model Registration No. 20-0387717 discloses an earplug 30 installed inside the ear protector 15 and having a donut shape and in close contact with the pilot's ear as shown in FIG. 1; A bone conduction speaker 40 installed at a portion where the bone around the ear of the earplug 30 contacts, and transmitting vibration to the bone around the ear; A microphone 50 installed at an outer portion of the ear protector 15 to convert voice into an electrical signal; Bone conduction using a bone conduction vibrator consisting of; an external connection jack (60) coupled to the wires (45, 55) for transmitting electrical signals of the bone conduction speaker 40 and the microphone (50) to the outside, The helmet is open to the public.

However, in the conventional technique as described above, since the bone conduction speaker is not closely adhered to the bone of the ear circumference accurately, accurate communication is impossible, and even if it is properly adhered, the ambient noise is also transmitted when communicating with the communicator using a general microphone. Incorrect communications have made it difficult to perform the mission.

The present invention is to solve such a problem, the bone conduction speaker is closely contacted to the bones of the ear can be accurately communicated, the accurate communication content by removing the surrounding noise when communicating with the communicator using the bone conduction microphone It is possible to perform a mission due to the, and to provide a pilot helmet using a vibrator to prevent psychological anxiety caused by noise even during long flight or operation.

Pilot helmet using the vibrator of the present invention for achieving the above object is provided with an earplug that is in close contact with the ear of the ear of the user, and a bone conduction speaker installed inside the earplug, to the bone of the ear of the pilot blocked with earplugs. Helmet main body to transmit the vibration of the voice signal received through the bone conduction speaker to hear the voice; And an elastic member installed between the bone conduction speaker and the earplug so that the bone conduction speaker is fixed to the bone around the user's ear.

The helmet body has a Y-shaped bone conduction microphone that converts the vibration of the larynx by the user's voice into an electrical signal and outputs it to the outside, and is connected to the bone conduction microphone to freely bend the bone conduction microphone to the user's larynx. Additional flex supports may be installed.

In addition, the elastic member is characterized by consisting of a spring and the fixing plate.

The present invention by the above solution means that the bone conduction speaker is in close contact with the bones around the left and right ears, it is possible to accurately communicate with the communicator, the eardrum is damaged by noise and accurate hearing can be received even those who are hearing deteriorated. It can be performed to prevent safety accidents, and through the bone conduction microphone located on the wearer's larynx, there is an effect that communication is possible by excluding surrounding noise (noise heard through air conduction).

In addition, there is an effect that can prevent psychological anxiety caused by noise during long flight or operation.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

As shown in the figure, the subject innovation consists of a helmet body 100 and an elastic member 150.

The helmet body 100 is provided with an earplug 110 that is in close contact with the ear circumference bone of the user, and a bone conduction speaker 130 installed inside the earplug 110, the ear circumference of the pilot blocked by the earplug 110. It is formed to transmit the vibration of the voice signal received through the bone conduction speaker 130 to the bone of the voice.

At this time, the helmet body 100 is provided in the hemispherical cushion belt 105 on the inner peripheral surface is made to protect the user's safety from external impact when the user wears.

In addition, the earplug 110 is installed inside the helmet body 100 and worn close to the bone around the user's ear, and has a donut shape having an accommodation space therein.

That is, the ear plug 110 is made of an elastic material in a donut shape so as to surround the ear to block the noise to the outside, and has an accommodation space therein so that the bone conduction speaker 130 and the elastic member ( It is formed by installing 150).

The bone conduction speaker 130 is to transmit the voice signal transmitted to the bone around the ear as a vibration, and installed in the inner accommodating space of the ear plug 110, when the contact sensitivity to the bones of the user's ear when the contact sensitivity Because it is excellent, install so that it can be in close contact with the bone around the user's ears.

At this time, the elastic member 150 is provided between the inner side surface of the ear plug 110 and the bone conduction speaker 130.

The elastic member 150 maintains the bone conduction speaker 130 in the direction of the bone around the user's ear so that the bone conduction speaker 130 is in close contact with the bone around the ear.

As such, the elastic member 150 is composed of a spring 153 having an elastic force, and the fixing plate 155 to fix the spring 153 to the ear plug 110 and the bone conduction speaker 130.

In addition, the helmet body 100 has a bone conduction microphone 170 that converts the vibration of the larynx by the user's voice into an electrical signal and outputs it to the outside, and the bone conduction microphone 170 is connected to the bone conduction microphone It consists of a bending support 175 that is bent freely to be located in the back of the user.

The bone conduction microphone 170 excludes ambient noise (the noise heard through air conduction) when the user communicates with the communicator, and enables the user to transmit a clean voice signal only by the sound of the larynx vibration.

The bending support 175 is formed in a Y-shape to fix a portion of the helmet body 100 and the bone conduction microphone 170 and to bend freely to a desired position by the user.

That is, when using the bone conduction microphone 170 to move to the user's larynx, when not in use to move to the top of the helmet.

As described above, the present invention allows the bone conduction speaker to be closely adhered to the bone of the ear circumference, thereby enabling accurate communication, and using the bone conduction microphone to perform the mission due to the accurate communication content excluding the surrounding noise when communicating with the communicator.
