[Modes for carrying out the invention]

[0019] To make it easier to further understand the above and / or other objects, effects, and features of the present invention, the following particularly preferred embodiments will be given and described in detail.

[0020] FIG. 1 is a flowchart showing a wireless transmission method according to an embodiment of the present invention. As shown in the figure, the steps of the wireless transmission method according to an embodiment of the present invention are as follows. Step S1: Provide transmission information. Step S2: Convert the transmission information and generate a corresponding conversion result. Step S3: Calculate the conversion result and generate a corresponding encoding result. Step S4: Transmit a corresponding sound wave signal based on the encoding result.

[0021] As shown in Step S1, transmission information is provided by a transmission end. The transmission information may be characters, images, voices, or a combination of the above.

[0022] As shown in Step S2, convert the transmission information and generate a corresponding conversion result. In one embodiment, the standard of Morse Code may be adopted, 26 characters and numbers may be displayed in binary mode, or other self-defined conversion standards may be adopted. The present invention is not limited thereto.

[0023] As shown in Step S3, calculations may be performed based on the conversion result to generate a corresponding encoding result. This encoding result may be to assign a corresponding sound wave signal based on the conversion result, for example, based on different combinations of sound wave frequency, sound wave intensity, or the duration of the sound wave signal. For example, sound wave signals with multiple different intensity levels may be provided and displayed. For example, sound wave signals with intensities of 30 dB, 35 dB, 40 dB, 45 dB, 50 dB, 55 dB, 60 dB, 65 dB, 70 dB, and 75 dB may be provided respectively. The present invention is not limited thereto.

[0024] In one embodiment, the transmission end may first transmit at least one default sound wave signal, and the receiving end may receive and process this default sound wave signal to generate corresponding default sound wave information. For example, the transmission end may provide multiple default sound wave signals of different sound wave intensities, each with a duration of less than 0.2 seconds, and the receiving end may determine its frequency sensitivity after receiving the sound wave signal. The default sound wave information may further include sound wave frequency, sound wave intensity, duration, position information, and distance information, and the algorithm determines which combination of sound wave frequency, sound wave intensity, and duration to adopt based on the sensitivity of the receiving end by determining the relative position and distance between the receiving end and the transmission end. In other words, in the process of transmitting sound wave signals, the transmission mass is likely to be affected by ambient noise interference and the distance between the receiving end and the transmission end, so the best encoding result is generated by determining the combination of sound wave signals to actually output after confirming the relative position and distance between the transmission end and the reception end using the sound wave signal.

[0025] In one embodiment, Figure 2A is a spectrogram showing one embodiment of the present invention. Figure 2B is a graph showing 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 regions. Region 1 is the audible sound wave signal and background noise. Region 2 is the sound wave signal output from the actual coding result. Region 3 is the sound wave signal output from the actual coding result, and a default sound wave signal for confirming the position information and distance information of the transmission end and reception end. As shown in Figure 2B, it is possible to correspond to the conditions measured in regions 1 to 3, and the combination of generated sound wave frequency, sound wave intensity, and duration is such that the transmission mass is maintained in the best state as the sound wave intensity at different sound wave frequencies changes over time.

[0026] In one embodiment, the algorithm estimates the relative position and distance between the transmitting end and the receiving end by performing calculations based on the change in sound wave intensity and the inverse relationship of the distance value between the transmitting end and the receiving end, thereby ensuring the transmission mass.

[0027] As shown in step S4, a corresponding sound wave signal is transmitted based on the encoding result, for example, by transmitting it so that it corresponds to different sound wave intensities at different sound wave frequencies as time changes, thereby indicating specific information data and transmitting it in sound wave signal format. The sound wave frequency of the sound wave signal may be in the range of 20 Hz to 2 MHz, and the sound wave signal may be a human-audible signal or an ultrasonic signal.

[0028] In one embodiment, steps S1 to S4 are an encoding process, and in detail, Figure 3 is a flowchart showing a part of a wireless transmission method according to one embodiment of the present invention. As shown in the figure, the decoding process includes the following steps. Step S5: The sound wave signal is processed to generate corresponding sound wave information. Step S6: Compare the sound wave information with the default sound wave information and generate the corresponding decoding result. Step S7: Calculate the decoding result and obtain the transmission information.

[0029] As shown in step S5, the receiving end receives the sound wave signal and performs calculations to generate corresponding sound wave information, obtaining the sound wave frequency, sound wave intensity, and duration corresponding to the sound wave signal. However, the present invention is not limited thereto.

[0030] As shown in step S6, the sound wave information obtained in the previous step and the default sound wave information are compared, and the corresponding decoding result is generated. In other words, by comparing it with the previously obtained default sound wave information, the encoded content corresponding to the currently obtained sound wave information is confirmed.

[0031] As shown in step S7, the decoding result is calculated, and the decoding result is converted to the corresponding transmission information using the conversion method in step S2, thereby achieving the objective of wireless transmission using sound wave signals.

[0032] Figure 4 is a schematic diagram showing a system according to one embodiment of the present invention. As shown in the figure, the system according to one embodiment of the present invention comprises an input unit 1, an encoding unit 2, an output unit 3, and a decoding unit 4. The encoding unit 2 has signals connected to the input unit 1 and the output unit 3, respectively, and the decoding unit 4 has a signal connected to the input unit 1. These will be explained in detail below.

[0033] Input unit 1 is used to input the transmission information to be transmitted. This transmission information may be text, audio, images, or a combination of the above.

[0034] In one embodiment, the input unit 1 further comprises a receiver 11 for receiving sound wave signals and generating corresponding sound wave information.

[0035] The encoding unit 2 performs conversion and encoding based on the transmitted information to generate the corresponding encoded result. The sound wave frequency, sound wave intensity, and duration of the sound wave signal may all be combinations of encodings, and the present invention is not limited thereto.

[0036] Output unit 3 is used to determine and output the corresponding sound wave signal based on the encoding result.

[0037] The decoding unit 4 performs calculations based on the sound wave information to generate a decoding result, then converts the data according to the decoding result, and also retrieves the original transmission information.

[0038] Figure 5 is a schematic diagram showing an apparatus according to one embodiment of the present invention. As shown in the figure, the apparatus according to one embodiment of the present invention comprises a first electronic device E1, a sound wave generator 5, a second electronic device, and a processing unit 6. The processing unit 6 has signals connected to the first electronic device E1, the sound wave generator 5, and the second electronic device E2, respectively, and the second electronic device E2 has a signal connected to the sound wave generator 5. These will be explained in detail below.

[0039] The first electronic device E1 is used to provide transmitted information. The first electronic device E1 may be an electronic device having numerical values, a smartphone, a smart tablet, a laptop computer, a personal computer, a 7-segment display, or any other electronic product capable of transmitting data. Examples of electronic devices having numerical values ​​include, but are not limited to, a blood pressure monitor, an oximeter, or a blood glucose meter.

[0040] The sound wave generator 5 can generate and transmit a corresponding sound wave signal based on the encoding result. Specifically, the sound wave generator 5 includes, but is not limited to, a crystal oscillator, a speaker, or a piezoelectric device.

[0041] In one embodiment, when a crystal oscillator is used as the sound wave generator 5, the circuit may be coupled to control the on / off state, and in this case, the encoding result may be determined by controlling whether or not power is supplied. In this way, the corresponding sound wave signal is transmitted, but the present invention is not limited thereto.

[0042] The second electronic device E2 is used to receive and process sound wave signals and generate corresponding sound wave information. In one embodiment, the second electronic device E2 includes at least one microphone, which may be a microphone or another device capable of receiving sound wave signals. Thus, the second electronic device E2 may be a smart speaker, television, smartphone, smart tablet, laptop computer, or earphones, and the second electronic device E2 may be any electronic product equipped with a microphone.

[0043] In one embodiment, the second electronic device E2 may be a hearable device used for receiving or transmitting sound wave signals, prompting, warning, etc., and may be integrated with an application program to implement complex functions in order to serve users who are blind or have visual impairments.

[0044] In one embodiment, if the microphone sensitivity is sufficiently high, the frequency range can be further reduced. For example, it may be from 500Hz to 300Hz, but the present invention is not limited thereto. Preferably, if the microphone sampling rate exceeds 96kHz, the range of the sound wave signal may be 24kHz to 48kHz.

[0045] The arithmetic processing unit 6 includes an encoding unit 61 and a decoding unit 62. The encoding unit 61 may perform conversion and encoding based on the transmitted information to generate a corresponding encoded result and transmit it to the sound wave generator 5.

[0046] In one embodiment, the encoding unit 61 may employ differential transmission technology to prevent interference during transmission. Alternatively, the encoding unit 61 may be packaged within Bluetooth®, Wi-Fi, LoRa (Long Range), or NB-IoT (Narrowband Internet of Things) and configured to encode using an integrated circuit (IC).

[0047] The decoding unit 62 may perform conversion and decoding based on 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.

[0048] To further clarify the method of implementing one embodiment of the present invention, Figure 6 is a diagram showing an embodiment according to one embodiment of the present invention. First, taking a 7-segment display as an example, A to G are sequentially labeled, and the decimal point is labeled DP, with A to G corresponding to different sound wave frequencies of sound wave signals. For example, A corresponds to 19kHz, B to 19.5kHz, C to 21.5kHz, D to 21kHz, E to 20.5kHz, F to 18.5kHz, G to 20kHz, and DP to 18kHz. These sound wave frequencies can be changed as needed. The preceding 2 seconds are the total number, for example, flashing for 0.4 seconds, off for 0.2 seconds, emitting light for 0.2 seconds, and off for 1.2 seconds. When displaying numbers, it is activated only once every 3 seconds (on / off) at a frequency. If the number is decimal, the frequency changes from once every 3 seconds (on / off) to once every 2 seconds (on / off). If the number is base-100, the frequency changes from once every 2 seconds (on / off) to once every 1 second (on / off). To accelerate the information transmission speed, each default frequency is divided by 10 or 100, but the present invention is not limited thereto.

[0049] To further clarify the method of carrying out one embodiment of the present invention, Figure 7 shows an embodiment according to one embodiment of the present invention. First, Morse code is given as an example, with the default frequency of the unit being 22 kHz. For example, (1) represents millimeters of mercury (mmHg), (2) represents percent (%), (3) represents centimeters (cm), (4) represents kilograms (kg), (5) represents liters (L), (6) represents mmol / L, (7) represents heart rate, and (8) represents Celsius temperature. Inches may be converted to centimeters (cm), pounds (lb), grams (g), and ounces (oz) may be converted to kilograms (kg), gallons (gal) may be converted to liters (L), and Fahrenheit temperature may be converted to Celsius temperature. In addition to the digits 0-9, a Morse code conversion standard for the letters A-Z may be adopted, and similarly, when accelerating the information transmission speed, each default frequency may be divided by 10 or 100, but the present invention is not limited thereto.

[0050] In summary, the wireless transmission method, system, and apparatus according to the present invention wirelessly transmits sound wave signals, performs pairing and configuration using a microphone in an electronic device, achieves the purpose of wireless transmission, and realizes a simple and high-speed wireless transmission method. At the same time, by adjusting the sound wave signal based on the on-site environment, the transmission mass is ensured, thereby achieving the objectives of the present invention.
