[0027] To make the above and / or other purposes, effects, and features of the present invention more clearly understood, preferred embodiments are described in detail below:

[0028] [Corrected 02.04.2024 in accordance with Rule 26] Please refer to Figure 1, which is a flow chart of a method according to an embodiment of the present invention. As shown in the figure, the wireless transmission method according to an embodiment of the present invention has the following steps:

[0029] Step S1: providing a transmission message;

[0030] Step S2: converting the transmission information to generate a corresponding conversion result;

[0031] Step S3: Calculate the conversion result to generate a corresponding encoding result; and

[0032] Step S4: transmitting a corresponding acoustic wave signal using the encoding result.

[0033] As shown in step S1 , a transmission end provides transmission information, wherein the transmission information can be text, image, voice or a combination thereof.

[0034] As shown in step S2, the transmission information is converted to generate a corresponding conversion result. In one embodiment, the Morse Code standard can be adopted, using a binary mode to represent 26 letters and numbers, or other customized conversion standards, but not limited thereto.

[0035] As shown in step S3, calculations are performed based on the conversion results to generate corresponding coding results. This coding result can be assigned a corresponding sound wave signal based on the conversion result, for example: based on the sound wave frequency, sound wave intensity or duration of the sound wave signal as different combinations, for example, sound wave signals of multiple different intensity levels can be provided to represent, for example, sound wave signals with intensities of 30dB, 35dB, 40dB, 45dB, 50dB, 55dB, 60dB, 65dB, 70dB and 75dB are provided respectively, but not limited to this.

[0036] In one embodiment, the transmitting end may first transmit at least one default sound wave signal, and the receiving end may receive and calculate the default sound wave signal to generate corresponding default sound wave information. For example, the transmitting end may provide a plurality of default sound wave signals with different sound wave intensities, and the duration of each sound wave intensity is less than 0.2 seconds. After the receiving end receives the sound wave signal, the frequency sensitivity of the receiving end is determined based on the signal. The default sound wave information may further include sound wave frequency, sound wave intensity, duration, position information and distance information, that is, the relative position and distance between the receiving end and the transmitting end are determined through an algorithm, and the combination of sound wave frequency, sound wave intensity and duration is determined according to the sensitivity of the receiving end. In other words, since the sound wave signal is likely to be affected by ambient sound interference or the distance between the receiving end and the transmitting end during transmission, which may affect the transmission quality, the relative position and distance between the transmitting end and the receiving end are confirmed through the sound wave signal, and then the actual output sound wave signal combination is determined to produce the best encoding result.

[0037] [Corrected 02.04.2024 in accordance with Rule 26] In one embodiment, please refer to Figures 2A and 2B, which are a time spectrum diagram (spectrogram) and a diagram of the change in sound wave intensity at different sound wave frequencies according to one embodiment of the present invention. As shown in Figure 2A, it is divided into three areas: Area 1 is the part of the audible audio and background noise; Area 2 is the sound wave signal output by the actual encoding result; and Area 3 is the sound wave signal output by the actual encoding result and the default sound wave signal used to confirm the location information and distance information of the transmitting end and the receiving end. As shown in Figure 2B, it can correspond to the conditions measured in areas 1 to 3. The combination of sound wave frequency, sound wave intensity, and duration generated thereby, that is, the sound wave intensity at different sound wave frequencies changes over time, so as to maintain the transmission quality at an optimal state.

[0038] In one embodiment, the algorithm calculates the relative position and distance between the transmitter and receiver based on the inverse proportional relationship between the change in sound wave intensity and the distance between the transmitter and receiver, thereby ensuring transmission quality.

[0039] As shown in step S4, a corresponding sound wave signal is emitted based on the encoding result. For example, as time changes, different sound wave intensities are emitted at different sound wave frequencies to represent a certain piece of information data and transmit it in the form of a sound wave signal. The sound wave frequency of the sound wave signal can be between 20 Hz and 2 MHz, that is, the sound wave signal can be a human audible signal or an ultrasonic signal.

[0040] [Corrected 02.04.2024 according to Rule 26] In one embodiment, steps S1 to S4 are the encoding process. Therefore, please refer to FIG3 , which is a flow chart of a portion of the method according to one embodiment of the present invention. As shown in FIG3 , the steps of the decoding process include:

[0041] Step S5: Calculate the sound wave signal to generate corresponding sound wave information;

[0042] Step S6: Comparing the sound wave information with the default sound wave information to generate a corresponding decoding result; and

[0043] Step S7: Calculate the decoding result to obtain the transmission information.

[0044] As shown in step S5, when the receiving end receives the sound wave signal and performs calculations, corresponding sound wave information is generated, that is, the sound wave frequency, sound wave intensity and duration of the corresponding sound wave signal are obtained, but not limited to this.

[0045] As shown in step S6, the sound wave information obtained in the previous step is compared with the default sound wave information to generate a corresponding decoding result. In other words, after comparing with the previously obtained default sound wave information, the encoding content corresponding to the currently obtained sound wave information is confirmed.

[0046] As shown in step S7, the decoding result is calculated and converted into corresponding transmission information by the conversion method of step S2, thereby achieving the purpose of wireless transmission through sound wave signals.

[0047] [Corrected 02.04.2024 pursuant to Rule 26] Please refer to Figure 4, which is a system diagram of one embodiment of the present invention. As shown in the figure, the wireless transmission system of one embodiment of the present invention includes: an input unit 1, an encoding unit 2, an output unit 3, and a decoding unit 4. The encoding unit 2 is signal-connected to the input unit 1 and the output unit 3, respectively, and the decoding unit 4 is signal-connected to the input unit 1.

[0049] In one embodiment, the input unit 1 may further include a receiver 11 for receiving sound wave signals to generate corresponding sound wave information.

[0050] The encoding unit 2 is used for converting and encoding according to the transmission information to generate a corresponding encoding result, wherein the sound wave frequency, sound wave intensity and duration of the sound wave signal can be used as a combination of encoding, but is not limited thereto.

[0051] The output unit 3 is used to determine and output a corresponding sound wave signal according to the encoding result.

[0052] The decoding unit 4 is used to perform calculations based on the sound wave information to generate a decoding result, and then perform corresponding conversion based on the decoding result to obtain the original transmission information.

[0053] [Corrected 02.04.2024 in accordance with Rule 26] Please refer to Figure 5, which is a schematic diagram of an apparatus according to an embodiment of the present invention. As shown in the figure, the wireless transmission apparatus according to an embodiment of the present invention includes: a first electronic device E1, an acoustic wave generator 5, a second electronic device, and a processing unit 6. The processing unit 6 is signal-connected to the first electronic device E1, the acoustic wave generator 4, and the second electronic device E2, respectively. The second electronic device E2 is signal-connected to the acoustic wave generator 4. The details are as follows:

[0054] The first electronic device E1 is used to provide transmission information, wherein the first electronic device E1 can be an electronic device with digital values, a smart phone, a smart tablet computer, a laptop computer, a personal computer, a seven-segment display or other electronic products that can transmit digital values, wherein the electronic device with digital values ​​includes but is not limited to a blood pressure monitor, a blood oxygen monitor or a blood glucose monitor.

[0055] The sound wave generator 5 can generate and transmit a corresponding sound wave signal according to the encoding result. Specifically, the sound wave generator 5 includes but is not limited to a crystal oscillator, a speaker or a piezoelectric device.

[0056] In one embodiment, when the sound wave generator 5 uses a crystal oscillator, it can be combined with a circuit for on / off control. At this time, the encoding result can determine whether the control is powered on or not, thereby emitting a corresponding sound wave signal, but this is not limited to this.

[0057] The second electronic device E2 is used to receive and calculate the sound wave signal to generate corresponding sound wave information. In one embodiment, the second electronic device E2 includes at least one microphone, wherein the microphone can be a microphone or other device that can receive sound wave signals. Therefore, the second electronic device E2 can be a smart speaker, a television, a smart phone, a smart tablet, a laptop computer, a personal computer or a headset. In other words, the second electronic device E2 can be any electronic product with a microphone.

[0058] In one embodiment, the second electronic device E2 may also be a hearable device that can be used to receive or transmit sound signals, reminders, alarms, etc. It can also be integrated with applications to implement complex functions and serve blind people or users with vision problems.

[0059] In one embodiment, when the sensitivity of the microphone is high enough, the frequency range can be smaller, for example, from 500 Hz to 300 Hz, but not limited thereto. Preferably, when the sampling rate of the microphone exceeds 96 Hz, the range of the sound wave signal can be between 24 kHz and 48 kHz.

[0060] The processing unit 6 includes an encoding unit 61 and a decoding unit 62 , wherein the encoding unit 61 can perform conversion and encoding according to the transmission information to generate and transmit a corresponding encoding result to the sound wave generator 5 .

[0061] In one embodiment, the encoding unit 61 may adopt differential transmission technology to prevent interference during transmission. In addition, the encoding unit 61 may be packaged in Bluetooth, Wi-Fi, LoRa (Long Range) or NB-IoT (Narrowband Internet of Things) and encode through an integrated circuit (IC).

[0062] The decoding unit 62 can convert and decode the sound wave information to generate a decoding result, and finally perform calculations based on the decoding result to obtain the corresponding original transmission information and output it to the second electronic device E2.

[0063] [Corrected 02.04.2024 according to Rule 26] To more clearly illustrate the implementation of an embodiment of the present invention, please refer to FIG6 , which is an implementation example of an embodiment of the present invention. First, take a seven-segment display as an example, and mark A to G in sequence, and mark DP at the decimal point. A to G correspond to different sound wave frequencies of the sound wave signal, for example, A corresponds to 19kHz, B corresponds to 19.5kHz, C corresponds to 21.5kHz, D corresponds to 21kHz, E corresponds to 20.5kHz, F corresponds to 18.5kHz, G corresponds to 20kHz, and DP corresponds to 18kHz. This sound wave frequency can be changed as needed, and the first 2 seconds can be the total number of digits. For example: flashing for 0.4 seconds, then off for 0.2 seconds, on for 0.2 seconds, off for 1.2 seconds; if it represents a number, it will only be turned on once every 3 seconds (on / off); if the number is a tens digit, then after a frequency of 3 seconds (on / off), it will be changed to a frequency of 2 seconds (on / off); if the number is a hundreds digit, then after a frequency of 2 seconds (on / off), it will be changed to a frequency of 1 second (on / off); if you want to speed up the message transmission, each default frequency will be divided by 10 or 100, but not limited to this.

[0064] [Corrected 02.04.2024 according to Rule 26] To more clearly illustrate the implementation of an embodiment of the present invention, please refer to Figure 7, which is an implementation example of an embodiment of the present invention. First, taking Morse Code as an example, the default unit frequency is 22kHz. For example, (1) represents millimeters of mercury (mmHg); (2) percent (%); (3) centimeters (cm); (4) kilograms (kg); (5) liters (L); (6) mmol / L; (7) heart rate; (8) Celsius temperature. Among them, inches can be converted to centimeters (cm), pounds (lb), grams (g) and ounces (oz) can be converted to kilograms (kg), gallons (gal) can be converted to liters (L), and Fahrenheit temperature can also be converted to Celsius temperature. In addition to the numbers 0 to 9, the Morse code conversion standard of letters A to Z can also be used.
