Abstract
Description
Technical Field
[0001] The utility model relates to communication equipment, and particularly to a wireless communication device that can be used simultaneously in media of air and water. Background Art
[0002] It is a great challenge for the same wireless communication mode to operate simultaneously in air and underwater, especially due to the absorption of most commonly used communication frequencies by water molecules. Polar water molecules change their orientation under the action of the electric field of electromagnetic waves. Therefore, when the communication device is underwater, the electromagnetic wave is greatly attenuated, making it difficult to achieve wireless communication underwater. However, in practice, what is needed is a device that can receive audio or data communication sent by a ground station whether the diver is underwater or has surfaced (before and after getting into the water). Although there are some technical problems, it is still necessary to continue to explore and meet such a demand in order to maintain the continuity and reliability of communication in any situation.

[0021] Please refer to Figure 1 , a wireless communication device that can be used simultaneously in media of air and water, including a ground communication device and a diver communication device. Both the ground communication device and the diver communication device include:
[0022] Microphone 103, connected to the modulation / demodulation amplifier 104; the user inputs voice information through the microphone, and this module can convert the sound signal into an electrical signal and input it into the modulation / demodulation amplifier for further processing. The microphone 103 can be a fixed desktop microphone in the ground communication device and an earphone worn by the diver in the diver communication device.
[0023] Modulation / demodulation amplifier 104, connected to the microphone 103, radio frequency transmitting / receiving module 101, ultrasonic transducer 105, and speaker 106; this module is used to process signals. For the input signals, the modulation / demodulation amplifier encodes them into a form that can be sent through the radio frequency module or ultrasonic transducer; for the received signals, the modulation / demodulation amplifier decodes them into electrical signals and then sends them in. It not only has the function of modulation and demodulation but also is responsible for further processing the signals encoded or decoded by the modulation / demodulation amplifier, performing noise cancellation, enhancing the signal strength, and optimizing the signal reception and transmission quality.
[0024] Radio frequency transmitting / receiving module 101, connected to the modulation / demodulation amplifier 104; this module is responsible for wireless communication in the air medium. It receives and sends radio frequency signals, which enables the device to communicate over long distances in the air.
[0025] Ultrasonic transducer 105, connected to the modulation / demodulation amplifier 104; this module is responsible for wireless communication in the water medium. It receives and sends ultrasonic signals, enabling the device to communicate in an underwater environment.
[0026] Speaker 106, connected to the modulation / demodulation amplifier 104; this module is responsible for playing the processed sound signal so that the user can hear the voice information of the other party. The speaker 106 can be a fixed horn in the ground communication device and an earphone worn by the diver in the diver communication device.
[0027] Power management module 102, connected to the microphone 103, modulation / demodulation amplifier 104, radio frequency transmitting / receiving module 101, ultrasonic transducer 105, and speaker 106. It is responsible for providing necessary power to all other modules to ensure their normal operation. In addition, it is also responsible for managing the power usage of the hardware, through effective power management strategies, to extend the battery life and reduce energy waste.
[0028] In another preferred embodiment, the radio frequency transmitting / receiving module 101 is a radio frequency transmitting / receiving module with an automatic frequency selection function. Automatic frequency selection is a technology that optimizes wireless communication by automatically detecting and selecting the best communication frequency. In an actual usage environment, wireless communication may be subject to electromagnetic interference from other wireless devices or electronic devices, resulting in a decline in communication quality. In such a situation, the radio frequency transmitting / receiving module 101 with an automatic frequency selection function can automatically check all available frequencies and then automatically select the frequency with the strongest signal intensity and the least interference for communication. In addition, this automatic frequency selection technology can also achieve dynamic frequency selection, that is, during the communication process, if interference occurs in the currently used frequency, it will automatically switch to other clearer frequencies, thus ensuring the stability of communication quality. Adding a radio frequency transmitting / receiving module with an automatic frequency selection function to a wireless communication device is undoubtedly a powerful means to improve communication quality and user experience.
[0029] In another preferred embodiment, the modulation / demodulation amplifier 104 is a modulation / demodulation amplifier with an automatic gain control function. Automatic gain control is a function that automatically adjusts the amplification factor of a received signal under changing signal intensity conditions so that the intensity of the output signal remains within an ideal and stable range. It is an important function possessed by many communication devices. When the intensity of the received signal is lower than a predetermined ideal value, the modulation / demodulation amplifier 104 will automatically increase the amplification factor of the signal, thereby increasing the intensity of the output signal. On the contrary, if the intensity of the received signal is too strong and exceeds the predetermined range, the modulation / demodulation amplifier 104 will decrease the amplification factor to reduce the intensity of the output signal, prevent signal overload, and ensure the quality of the signal.
[0030] In another preferred embodiment, the ultrasonic transducer 105 includes one or more piezoelectric material layers. Piezoelectric material is a material that can convert mechanical pressure into voltage. Using this material in an ultrasonic transducer can generate a pressure wave by applying a voltage when an ultrasonic signal needs to be transmitted; similarly, when receiving an ultrasonic signal, the received pressure wave will cause a voltage change, which can then be recognized and processed by the device. Therefore, if the ultrasonic transducer 105 includes one or more piezoelectric material layers, it will have stronger signal conversion ability, can transmit and receive ultrasonic signals more accurately, and thus improve the overall performance and accuracy of the device.
[0031] In another preferred embodiment, the power management module 102 includes a battery charging indicator for real-time display of the battery charging status. This is a very practical design because it can display the battery charging status in real time, enabling the user of the device to understand the power status in real time.
[0032] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
