Description

RF transmitter receiver device with earplug function EAR-MUFF WITH INTEGRATED RF TRANSCEIVER}

The present invention relates to an RF transmitter and receiver device having an ear plug (EAR-MUFF) function, and in particular, an existing RF wireless audio, video and data transceiver built into an ear plug or a headphone or a headset, such as an airport, a port, a trap and an industrial site. The present invention relates to an RF transceiver apparatus device having an earplug function having a noise suppression function at a work site.

EAR-MUFF is used to prevent noise in environments with high noise and mechanical noise, such as airports, harbors, shooting ranges, and engine rooms. RF radio transceivers are used for reporting situations or for communication between workers.

In addition, in general wireless headphones, a wireless headphone system capable of transmitting a signal by infrared rays from a transmitter and receiving it at a position away from the transmitter has been put to practical use.

However, if you want to use the RF wireless transceiver hands-free with the wireless headphones as described above, you can attach or attach it by using parts other than your hands, such as waist, shoulder, neck or pocket, or other tools. You should use earphone, headphone, headphone with microphone.

In addition, when the light receiving portion is mounted in the headband portion, there is a fear that the light receiving water is blocked by the hair, so that it is impossible to receive the transmission signal transmitted from the transmitter.

In addition, when using a headset, an operation switch such as a volume is located at a place separate from the microphone. In such a case, it becomes very cumbersome to operate the switch with the earplugs attached.

In addition, since the channels of RF radio transceivers are mainly indicated by numbers, if a user wants to use a predetermined channel between the operator and the coordinator, the channel numbers must be memorized or recorded. Therefore, when an emergency occurs, for example, an accident occurs and the operator forgets the channel number or loses the recording paper, it is difficult to achieve a substantial call.

In addition, in a typical headset, since the earplug portion of the headset needs to be disassembled or removed when troubleshooting and replacing the microphone portion, it is very inconvenient because its repair and replacement method must be complicated and careful.

An object of the present invention is to solve the problems of the prior art as described above, and to provide an RF transmitter and receiver with a noise protection function in the workplace, such as airports, harbors, ships and industrial sites.

Another object of the present invention is to provide an RF transceiver apparatus having an earplug function that can be used as a hand-free RF transceiver.

Another object of the present invention is to provide an RF transceiver apparatus having an earplug function that can easily adjust the operation panel of the RF transceiver.

It is still another object of the present invention to provide an RF transceiver apparatus having an earplug function that can easily perform troubleshooting and replacement in a headset of an RF transceiver.

Still another object of the present invention is to provide an RF transceiver apparatus having an earplug function for illuminating a light at night.
