Description

Open-ended Intercom Headset {Open Set Intercom Headset}

The present invention relates to an omni-directional two-way voice communication headset, and more particularly, to an omnidirectional two-way voice communication headset capable of maintaining a dialogue using a normal hearing organ, And more particularly to an open two-way voice communication headset using a bone conduction earphone and a microphone.

In order to perform bidirectional communication (voice transmission) in general wired and wireless communication fields, a handset in which a handset for receiving a voice signal and a handset for inputting a voice signal are respectively widely used. Such a receiver may be a speaker or an earphone, and a microphone may be a transmitter. In particular, such a tuner and a telephone receiver are integrated into a headset, so that a user can freely use his or her hands.

However, the problem of such a headset is that there is a problem that the transmitter also transmits ambient noise around the user to the other party, and the weight and volume of the headset are increased due to separation of the transmitter and receiver, It is pointed out.

As an alternative to the disadvantage of a headset with a separate handset and handset, a user's voice is not picked up from the mouth, but rather a bone conduction microphone or speaker picked up through bone conduction in the user's ear canal Has been developed and used. Such a bone conduction device has a smaller weight and volume than a headset, so that it is convenient to use, and the voice signal received through the bone conduction suppresses the ambient noise to some extent.

On the other hand, in the process of performing bidirectional communication such as a clinician in operating room, a traffic police, and a war scout in a military ambush operation, unnecessary noise is filtered out to the surrounding party, It is also important to be able to transmit, but it is also important to be configured to be able to listen to the audible frequency bands such as the surrounding popularity or the voice of a neighbor. That is, the surrounding noise is not completely removed, but the transmitted voice signal is transmitted in a state in which the ambient noise is completely removed. However, among the surrounding noises, a configuration is required so that the sender can listen to the sound necessary for the sender.

The practice of working in a noisy environment is an example in many industrial sectors. Until now, devices that address this problem have been centered on devices that protect auditory functions from noise. Devices that prevent noise-induced hearing loss due to noise environment are mainly used through ear plugs or ear muffs. These work environment noise problems are managed through noise regulation standards and industrial disaster standards provided by the Ministry of Environment. However, there are special conditions that can cause problems when wearing a device that blocks external sounds in a place where there is noise in the working environment and everyday life. When a small noise is heard from the outside, a warning sound must be heard, and such a warning sound plays a very important role in working and living. For example, patrols in the operating room, army (DMZ patrol) and traffic patrol / guard as described above.

The open type bidirectional voice transmission headset 100 constructed as described above can be used in various environments such as an operating room environment, an army environment, a traffic patrol environment, and a security environment.

Currently, the use of the latest equipment is increasing rapidly in the operating room. However, the noise generated from these devices and the sound from the air conditioner is an average of 62 decibels (self-measured value), and the masks and ears that need to be used in the operating room reduce the discriminatory power of speech that is essential for conversation. In this environment, the high frequency band, which is important for enhancing speech discrimination power, is amplified through a unit mounted in the bidirectional communication unit, thereby enabling accurate communication in a noisy environment. This can also be used in ICUs and emergency rooms where surgery and emergencies occur.

8 is a photograph showing a sample of an open type bidirectional voice transmission headset 100 according to an embodiment of the present invention and a state worn by a surgeon. As shown, there is no discomfort because there is no mounting surface on the forehead (H) differently from existing products. In other conventional products that are mounted on the forehead band in the forehead during surgery, sweating may occur after a certain period of time, which may contaminate the surgical site. The open bidirectional voice transmission headset 100 of the present invention is also preferable for performing operations such as microscopic operation or robotic surgery, in which the face is closely contacted to the equipment.

Other headsets of similar shape, now made of plastic, are equipped with several units with a certain weight, which is a limitation. It can be confirmed that the open bidirectional voice transmission headset 100 of the present invention is correctly mounted on the right thigh cartilage surface. Several units are mounted externally to the headset using a minimum of wires (H). The position of the two-way communication unit 130 is mounted on the upper right portion of the headset 100. When operating room is taken as an example, it can be seen that the headset is placed comfortably even when the operation hood (T) covers the ears. It can be confirmed that even if the neck N is thick, it is mounted without inconvenience. This configuration allows a modified sound amplified by a certain frequency to be additionally played through the bone conduction through the two-way communication unit 130 even when a certain acoustic resistance is generated during conversation by wearing a hood and a mask, Keep speech discrimination.

In the military environment, the communication units used by the existing world pundits communicate with one ear and two ears shielded in the form of a muff, and they use a north microphone. In the case of a voice microphone, Respectively. It is important to recognize the sound through the natural eardrum because it is necessary to focus on the minute sound of 40 decibel or less when it plays a role of the first searcher. When using a north microphone, it is necessary to utter a decibel above a certain decibel in order to accurately communicate, which can be fatal in the case of a sharp search. It is the voice microphone that complements these disadvantages. However, in order to improve the accuracy of the communication sound, the vocal microphone also has a drawback in that it is necessary to apply a constant pressure to the vocal microphone with the finger. This is fatal in a confrontation situation where two hands are used and the personalization machine must be continuously mounted. The headset of the present invention solves all of these situations.

In the traffic patrol environment and in the security environment, when controlling in the road, use natural eardrum hearing and both ears to recognize the beeping sound of the car and the moving direction of the car. Even in the case of guardians, the use of both ears is imperative to recognize a fine alert signal. The headset of the present invention makes accurate communication in this environment.

It should be noted that the embodiments of the present invention disclosed in the present specification and drawings are only illustrative of the present invention in order to facilitate description of the present invention and to facilitate understanding of the present invention and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
