[0024] Example 2

[0025] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0026] In this embodiment, the hands-free communication device 1 also includes a microphone connection hole 104, a hands-free button 105, a simplex button 106, a volume potentiometer 107, a hands-free indicator light 108, a simplex indicator light 109, and a bracket 110. One hands-free communication device 1 is installed in the driller's cabin, and the other hands-free communication device 1 is installed on the drilling rig platform. The loudspeaker assembly 4 is installed outside the driller's cabin.

[0027] The bracket 110 is fixed to the top of the enclosure 101 by bolts, and the top of the bracket 110 is fixedly connected to the speaker 103.

[0028] The microphone connection hole 104 is located at the lower end of the surface of the housing 101. The hands-free button 105, the simplex button 106, the volume potentiometer 107, the hands-free indicator light 108, and the simplex indicator light 109 are all installed on one side of the surface of the housing 101.

Microphone connection hole 104 is used to connect to microphone body 2. The housing 101 also houses an amplifier transformer, power amplifier module, and voice equalizer. After the host is powered on, pressing hands-free button 105 on either the host or slave will illuminate hands-free indicator light 108, allowing the host and slave to communicate via microphone body 2. The volume of speaker 103 can be adjusted by rotating volume potentiometer 107. After communication ends, either... If one party presses the hands-free button 105 again, the hands-free indicator light 108 will turn off, ending the communication and putting the device into standby mode. In cases of excessive outdoor noise or special circumstances, simplex communication mode can be used. Press and hold the simplex button 106 until the simplex indicator light 109 lights up, and you can make a call. The slave speaker will then output sound. Release the simplex button 106, and the simplex indicator light 109 will turn off, and the slave speaker will be in answer mode. The slave personnel can use the same method to make simplex calls. When you need to make a call to on-site personnel, press and hold the hands-free button 105 to make a call through the microphone 2, and the loudspeaker 42 will output sound, thus enabling you to instruct on-site personnel to work.

[0032] In use, the two hands-free communication units 1 are the master and slave units, respectively. The master unit is installed inside the driller's cabin, and the slave unit is installed on the drilling platform. The loudspeaker 42 is installed outside the driller's cabin. After the master unit is powered on, either the master or slave unit can press the hands-free button 105, illuminating the hands-free indicator light 108. The master and slave units can then communicate with each other through the microphone body 2. The volume of the speaker 103 can be adjusted by rotating the volume potentiometer 107. After communication ends, either unit can press the hands-free button 105 again, turning off the hands-free indicator light 108, thus ending the communication and putting the device into standby mode. In cases of excessive outdoor noise or special circumstances, simplex communication mode can be used. Press and hold the simplex button... When the simplex button 106 is held down, the simplex indicator light 109 illuminates, allowing for communication. The slave unit's speaker then outputs sound. Releasing the simplex button 106 turns off the simplex indicator light 109, and the slave unit's speaker becomes active. Slave personnel can use the same method for simplex communication. To communicate with on-site personnel, press and hold the hands-free button 105, which allows communication through the microphone 2. The loudspeaker 42 outputs sound, enabling instructions to be given to on-site personnel. Through the combined use of the main unit, slave unit, microphone 2, communication junction box 3, and loudspeaker 4, real-time communication can be achieved during drilling operations, improving communication quality and work efficiency.
