In an embodiment, the sound signal is sequentially sampled according to a sampling range, and the sampled sound signal is compared with the reference value, and the sound signal higher than the reference value is set as the first data, for example, "1" Or "high", the audio signal below this reference value is set to the second data, such as "1" or "low", and the audio signal is decoded accordingly.

FIG. 2A is a schematic diagram of a frame format according to an embodiment of the invention. Taking the network connection setting information as an example, the frame format 200 includes a first information field 201 for instructing the electronic device 110 to start receiving network connection setting information, and a second information field 202 for The length of the network connection setting information transmitted by the electronic device 110 is indicated, and a third information field 203 is used to indicate the network connection setting information. In other words, the encoder 123 of the external device 120 encodes the network connection setting information into an audio signal 130 according to the frame format 200 and transmits it through the sound transmitter 121. When the audio receiver 111 of the electronic device 110 receives the audio signal 130, the decoder 113 decodes the audio signal 130. Since the decoded audio signal has the frame format 200, the electronic device 110 After receiving the first information field 201 of the frame format 200, the subsequent information is that the subsequent information is related to the network connection setting information and starts to be received, and the electronic device 110 receives the second frame format 200. After the information field 202, the length of the network connection setting information that should be received will be known.

Figure 2B shows an audio signal transmission and sampling method. Taking the audio signal 130 as an example, when the encoder 123 encodes the network connection setting information into the audio signal 130, the encoded audio signal 130 is split into the first audio signal 220 and the second audio signal 221. The information contained in the first audio signal 220 corresponds to the information of the first information field 201 of the frame format 200, and the information contained in the second audio signal 221 corresponds to the information of the second information field 202 of the frame format 200. And the network connection setting information of the third information field 203 thereafter, and after the first audio signal 220 is transmitted, the second audio signal 221 is transmitted to the sound receiver 111. In this embodiment, the first audio signal includes a first start signal 2201 having a main frequency and a duration T1, and a second start having a frequency that is different from the main frequency of the first start signal 2201 and having a duration of T2. Signal 2202. Preferably, the first audio signal can be a fixed frequency signal, and the second start signal 2202 can be a silent segment for highlighting the first start signal 2201, so that the electronic device 110 can easily interpret the first start signal 2201. In the actual implementation, as long as the first start signal 2201 and the second start signal 2202 have quite different frequencies, it is sufficient for the system to recognize, and is not limited to this embodiment. Since the transmission and detection methods of the frequency domain coding in this embodiment can effectively reduce the influence of external noise during the transmission of the voice signal, which may be affected by the noise of the surrounding environment, the influence of the external noise is effectively increased. The correctness and success rate of voice signal transmission.

Before the start of the audio signal transmission and sampling, since the decoder 113 cannot confirm when the first audio signal 220 can be received, the sampling start point of the audio signal is first confirmed by overlapping sampling. Accordingly, when the decoder 113 oversamples the audio signal 220 with a first sampling range, the sampling signal changes according to the amount of the audio signal 220 being sampled, as indicated by reference numeral 211. The variation of the sampling signal, wherein the length of the first sampling range may be preset to be greater than or equal to the duration T1 of the first start signal 2201. When the first audio signal 220 is initially sampled, since no audio signal is sampled, the sample signal 212 is flat. As the amount of the first audio signal 220 is increased, the frequency of the first start signal 2201 detected in the sampling signals 213 and 214 gradually increases. When the complete first start signal 2201 is sampled, this The sampling signal 215 at the time has a maximum value for the frequency strength of the first start signal 2201. Then, as the amount of the first start signal 2201 sampled is gradually decreased, accompanied by a second start signal 2202 having a frequency different from the first start signal (mute with the present embodiment), the sampling signals 216 and 217 are detected. The measured frequency strength of the first start signal 2201 begins to decrease. In other words, the sampled signal strength will gradually increase first, such as the sampled signals 212-215, and then gradually decrease, such as the sampled signals 215-217. The sample signal 215 is a reversal of the intensity of the sampled signal. Therefore, the starting point of the first audio signal 220 can be detected by the above process, and then the decoder 113 decodes the first information field 201. News. Since the time of the first audio signal 220 and the second audio signal 221 can be a preset value, the first audio signal 220 is confirmed. After the sampling start point, a second sampling range can be directly used, for example, every second time length T3, the second audio signal 221 is sequentially non-overlapping, without using the overlapping sampling method for sampling. Therefore, the computational complexity of sampling can be greatly reduced. It should be noted that the first audio signal 220 and the second audio signal 221 are sampled by different sampling ranges. However, in other embodiments, the same sampling range may be used for the first audio signal 220 and the second. The audio signal 221 is sampled.

In an embodiment, the decoder 113 of the electronic device 110 first performs overlapping sampling on the first audio signal 220 with a first sampling range to obtain a plurality of sampling signals, and confirms the first audio according to the maximum sampling signal. The sampling start point of the signal 220 is sampled and the first audio signal 220 is decoded. Then, the decoder 113 performs non-overlapping sampling and decoding on the second audio signal 221 by using a second sampling range according to the sampling starting point. Accordingly, the electronic device 110 can log in to the wireless network base station 140 according to the SSID and the login password of the wireless network base station carried in the decoded audio signal, and connect the network 150 according to the decoded audio signal. The login password of the web server is logged into the web server 160. Accordingly, the image captured by the electronic device 110 can be uploaded to the web server 160.
