FIG. 3 is a circuit diagram schematically illustrating a configuration of a multi-channel single sideband transmitter applied to a transceiver unit of the present invention.

The voice signal frequency f _s transmitted from the microphone 33 is filtered by a low pass filter (LPF) and amplified by a low frequency amplifier (LF AMP). Therefore, a low frequency voice signal frequency f _s is generated, modulated by the first modulator BM1 together with the carrier f _c1 generated from the first carrier oscillator CO1, and the first band filter BPF1 is The filtered signal f _c1 + f _s is output.

The filtered signal f _c1 + f _s is modulated by the second modulator BM2 together with the carrier f _c2 generated from the second carrier oscillator CO2 and filtered through the second band filter BPF2. The multi-carrier signal f _c2 + (f _c1 + f _s ) is output.

FIG. 5 is a circuit diagram schematically showing a configuration of an SSBTransducer applied to a transceiver unit of the present invention.

Antenna (501) is a device that enables the transmission of radio waves between devices. Since the medium (underwater) is different from the air, actual attenuation occurs a lot, and thus the device can radiate the most effective power.

The transmission / reception switching device (Relay) 502 is a device for distinguishing transmission and reception, and is currently switched to the PTT method.

Band pass filters (503, 515) are used to obtain the maximum gain and power at the desired frequency band (30 KHz) for the signals coming into and out of the antenna 501 in the actual transmission and reception.

The RF AMP (Radio Frequency Amplifier) 504,514 may provide sufficient power to transmit the wave because the gain may be sufficient at the transmitting end but not large enough to be transmitted externally in terms of power, and the antenna 501 at the receiving end. The incoming signal is attenuated in the water and is a weak signal. The signal is made large enough to demodulate it. In this case, if the noise component is reduced, good performance can be obtained.

Balanced modulator (505, 513) is a modulator that generates DSB signals. Modulation is a method that transmits voice information in higher frequency signals (carrier wave) because the voice is attenuated and cannot be transmitted far. Say Unlike the general AM modulation, the balance modulator removes carrier information and passes only the two sidebands (upper wave: USB, lower side band: LSB).

Carrier Oscillator (506) generates a carrier 30khz, and consists of a crystal oscillator (30khz) and an amplifier and has a considerable frequency stability, there should be no frequency fluctuations even if the external load fluctuations. Otherwise, the modulation frequency will change, resulting in loss of information.

When transmitting, it is sent with a voice. When receiving, it is used to find information from the receiving wave. As a feature of the SSB method, a carrier is required for both transmission and reception.

AF AMP (Audio Frequency Amplifier) (507,512) is a low frequency amplifier that handles voice, and it is required to amplify the signal input through the microphone to increase the gain and to amplify the weak signal from the balance modulator when receiving.

LPF (Low Pass Filter: 508, 511) is a DC part that passes the signal coming into the microphone 510 and the speaker 509 through only 300hz-3khz, which is the frequency band actually required in the voice bandwidth (20hz-20khz), This part removes high frequency band which is weak to noise.

The speaker (509) is the final stage of the receiver. It converts the voice signal past the low frequency amplifier and the low pass filter into an audible sound. It should be low output, strong in noise and durable. The speaker part is located on the headband of the mask and can be changed according to the person.

The microphone (510: 510) is the part that converts the voice of a person's voice into an electrical signal. The result of the actual work is that the bubble and breath sound act as the biggest variables. The high frequency part can be removed by the low pass filter. It has good sensitivity and noise.

In the present invention, the center frequency is in the range of 30 to 100KHz, but the optimum frequency (32.768KHz) can be selected by experiment, and the bandwidth is in the range of 300 to 3000KHz, but the low pass filter (LPF) and the band filter ( Band Pass Filter (BPF) is used to separate the bands, and it is preferable to apply an Amplitude Modulation (AM) or Single Sideband Modulation (SSB) method to facilitate low power as a modulation method. .

The battery corresponding to the power supply unit 20 may apply a voltage of 3 to 9V.

The underwater mask according to the present invention is manufactured to maintain the weight of the remaining portion except the weight of the battery 200g or less.

Wireless communication transceiver applied to the present invention may vary depending on the surrounding environment, but can be used in the range of about 50 ~ 500m depth, the present invention mainly proposes a system for transmitting a voice signal, but in the future development Therefore, even data signals and video signals may be transmitted.

In the present invention, a method of controlling by using a digital signal processor (DSP) is applied, and a push-to-talk (PTT) method is adopted as a transmission / reception switching method, but two frequencies are used in the future. Of course, it is also possible to adopt a full duplex (Full Duplex) method that can simultaneously transmit and receive multiple times regardless of the state of the opponent.

For reference, the underwater mask of the present invention can be further improved in the future, as mentioned briefly above, but it is to be clarified that the fundamental technical idea originates from the structure of the present invention. In other words, the problems to be solved in the future include the expansion of transmission media such as the expansion of the transmission bandwidth, the miniaturization of the transceiver unit by the use of low power, and the full duplex method for enabling simultaneous multiplexing. These include applications, clear solutions to the attenuation of transmission signals with depth, integration of a fully digital transceiver, and diversification of transmission and reception channels using phase locked loops (PLLs).

As described above, the underwater mask provided with the wireless communication transceiver of the present invention is provided with a power supply unit detachable on one side of the mask body, and a wireless transceiver unit including an antenna, earphones and a microphone to provide wireless It can transmit / receive without any obstacle to the wearer's movement, easy to operate and easy to use even for beginners, and because it does not use wired cable, it does not need additional facilities to wind it, so that the equipment can be light and simplified.
