Description

Communication equipment using vibration of vocal cords {Communication equipment using vibration of the vocal cords}

The present invention relates to a communication device using the vibration of the vocal cords, to minimize the input of external noise by receiving only the vibration by the vibration of the vocal cords using a vibration sensor, to shorten the manufacturing process by simplifying the structure of the input device, It is to reduce the manufacturing cost.

The human voice is a vibrating sound that vibrates from the vocal cords in the larynx and is also called a voice. The range of human voice is 80㎐ ~ 1280㎐.

Currently, as a device for voice communication, communication devices such as mobile phones and walkie-talkies are common, and communication aids such as hands-free for drivers' convenience are also used.

However, since communication devices such as mobile phones, walkie-talkies or hands-free are used in direct contact with a person's ear and mouth, the communication device cannot be used when a gas mask is worn due to fire suppression. Since the voice is transmitted after the switch is pressed, the radio cannot be used even when working with both hands.

In order to solve the above problems, the present inventors filed a utility model registration application No. 2001-25172, 'Communication device using vibration of the vocal cord' on August 20, 2001, and was registered on October 31, 2001. Due to the complicated structure of communication device, there were many difficulties in manufacturing.

In addition, when the input device is used as a general type such as a dynamic microphone or a condenser microphone, external noise penetrates and it is difficult to make a high quality call because it detects vibration caused by sound.

Therefore, an object of the present invention is to solve the above-mentioned problems, by blocking the external noise by receiving a voice signal to the vibration sensor, by simplifying the structure of the input device to shorten the manufacturing process, manufacturing cost The present invention provides a communication device using vibration of the vocal cords.

Communication apparatus using the vibration of the vocal cords according to the present invention for achieving the above object, the control box is installed in the binding port is connected to the vibration sensor, earphones and connectors by a cable, vibration to convert the vibration of the vocal cords into an electrical signal It is characterized in that the sensor case is fixed to the sensor is installed on one side end of the support.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the present invention to be described in detail.

1 is a perspective view of a communication device using the vibration of the vocal cords according to the present invention, the sensor case 11 is inserted into a fixed vibration sensor (1) for receiving the vibration of the vocal cords into an electrical signal, the user's neck It is installed at one end of the support (3) to prevent it from being separated.

Here, the support (3) is coated on a high elastic elastic body with a synthetic resin material, to be detachable to the user's neck, the synthetic resin material to protect the user's neck using a soft material.

On one side of the control box 4 in which the main board (not shown) for processing and controlling the signal input to the vibration sensor 1 is installed, a fastener 41 is installed and attached to the user's body.

The main board embedded in the vibration sensor 1 and the control box 4 is electrically connected by a cable 6, and the earphone 2 which outputs the voice of the other party is also connected to the main board and the cable 6. Is electrically connected.

In addition, a connector 5 for connecting the control box 4 having the main board and the radio (not shown) is electrically connected to the main board by a cable.

Figure 2 is a block diagram of a communication device using the vibration of the vocal cords according to the present invention, a vibration sensor (1) for converting the vibration of the vocal cords into an electrical signal, and OP for amplifying the signal input from the vibration sensor (1) Amp 42, a filter circuit 43 for removing noise from the signal amplified by the OP-Amp 42, and outputting only a voice signal; and a TR for amplifying the voice signal output from the filter circuit 43. An amplification circuit 44, an OP-Amp 42 'for re-amplifying the signal amplified by the OP-Amp 42, and a microcomputer 45 for controlling the signal amplified by the OP-Amp 42'. And a connector 5 for outputting signals from the TR amplification circuit 44 and the microcomputer 45.

Here, the microcomputer 6 is a microprocessor (a processing device integrating a computer computing device and a control device in one small silicon chip), and corrects the frequency of the amplified signal and may have a voice signal having a predetermined voltage or more. It outputs an on signal to transmit a voice signal only, and sets a delay time to maintain a transmission state even when the user does not input a voice for a short time due to breathing or the like.

The present invention may be modified in various ways without departing from the basic concept according to the needs of those skilled in the art.

As described above, according to the present invention, the vibration sensor is used to receive only the vibration caused by the vibration of the vocal cords, thereby minimizing the input of external noise, simplifying the structure of the input device, shortening the manufacturing process, and reducing the manufacturing cost. It can be effective.
