[0032] In order to make the objects, technical solutions and advantages of the present application clearer, the following will be described by specific embodiments in conjunction with the accompanying drawings.
[0033] Please refer to Figures 1 to 7 , the Bluetooth wireless transmission method, device and system provided by the embodiments of the present application will be described.
[0034] Please refer to Figure 1 The embodiments of the present application provide a Bluetooth wireless transmission method, which is applied to an audio transmission scene between intelligent devices, and includes the following steps.
[0035] S110, acquiring a first audio signal.
[0036] Specifically, the first audio signal can be acquired through an audio input port or a TYPE-C port supporting audio data transmission, and correspondingly, the audio input port or the TYPE-C port is connected with the intelligent device.
[0037] S120, encoding and decoding the first audio signal in a classic Bluetooth mode or an LE Audio mode to obtain a first radio frequency signal.
[0038] Specifically, the first audio signal can be coded and decoded in a classic Bluetooth mode or in an LE Audio mode, realizing compatibility and selectivity of the classic Bluetooth mode and the LE Audio mode.
[0039] S130, transmitting the first radio frequency signal.
[0040] Specifically, the first radio frequency signal can be transmitted through a radio frequency antenna, so that the function of the transmitting end can be realized.
[0041] In the embodiment of the application, the method can be applied to audio transmission between two smart devices. The Bluetooth audio technology-LE Audio (Low Energy Audio) improves audio quality and reduces latency. By supporting both classic Bluetooth mode and LE Audio mode, switching between various application scenarios can be realized, and high-quality audio requirements can be realized without replacing smart devices, achieving a balance between technology promotion and low-cost requirements.
[0042] The Bluetooth wireless transmission method provided by the embodiment of the application has at least the following technical effects: compared with the conventional technology, in the method of the embodiment of the application, the first audio signal is obtained first, and then coded and decoded in the classic Bluetooth mode or the LE Audio mode according to user requirements to obtain the first radio frequency signal carrying regular quality audio or high-quality audio, and finally the first radio frequency signal is transmitted. The LE Audio mode has the effects of low noise and low latency, and the coexistence of the classic Bluetooth mode and the LE Audio mode is retained, meeting various user requirements.
[0043] In combination with the above transmitting step, in some embodiments, before the first audio signal is obtained, the method comprises: starting a Bluetooth grouping protocol mode; transmitting a first grouping signal; determining whether a first grouping success signal is received; if the first grouping success signal is received, confirming that the grouping is successful.
[0044] For example, the first grouping signal is transmitted through a radio frequency antenna, and it is determined whether the first grouping success signal is received, and if the first grouping success signal is received, it is confirmed that the grouping is successful. After the grouping is successful, audio transmission can be performed.
[0045] It can be understood that through the Bluetooth grouping protocol mode, the grouping between smart devices can be realized, so that the transmitting function can be successfully realized and the accuracy of transmission can be ensured.
[0046] Please refer to Figure 2In some embodiments, before the first audio signal is acquired, or after the first radio frequency signal is transmitted, the method further comprises: S140, receiving a second radio frequency signal; S150, encoding and decoding the second radio frequency signal in a classic Bluetooth mode or an LE Audio mode to obtain a second audio signal; and S160, outputting the second audio signal.
[0047] Specifically, the second radio frequency signal can be received by a radio frequency antenna, thus realizing the function of the receiving end; the second radio frequency signal can be encoded and decoded in the classic Bluetooth mode or the LE Audio mode, thus realizing the compatibility and selectivity of the classic Bluetooth mode and the LE Audio mode; the second audio signal can be acquired through an audio input port or a TYPE-C port supporting audio data transmission, and the audio input port or the TYPE-C port is connected to the smart device.
[0048] By judging whether the transmitted signal or the received signal is received, it is determined whether to switch to the transmitting state or the receiving state, thus realizing the switching of the transmitting end and the receiving end.
[0049] In combination with the above receiving step, in some embodiments, before the second radio frequency signal is received, the method comprises: starting a Bluetooth grouping protocol mode; receiving a second grouping signal; judging whether the second grouping signal meets the Bluetooth grouping protocol mode; and if so, transmitting a second grouping success signal.
[0050] For example, the second external grouping signal is received by a radio frequency antenna, and it is judged whether the second grouping signal meets the Bluetooth grouping protocol mode; if so, a second grouping success signal is transmitted, and a prompt sound or an indicator light can also be outputted. After the grouping is successful, audio transmission can be performed.
[0051] It can be understood that, through the Bluetooth grouping protocol mode, the grouping between smart devices can be realized, thus realizing the receiving function smoothly and ensuring the accuracy of the receiving.
[0052] When applied to the transmitting end, in some embodiments, before the first audio signal is acquired, or after the first radio frequency signal is transmitted, the method further comprises: judging whether a local recording mode is started; if so, acquiring a first sound signal of a microphone; encoding and decoding the first sound signal in a classic Bluetooth mode or an LE Audio mode to obtain a third audio signal; and storing the third audio signal.
[0053] Specifically, when the local recording mode is started, the second sound signal obtained by the built-in microphone or the external microphone is converted into the third audio signal and stored locally, thus realizing the local recording effect.
[0054] When applied to the transmitting end, in some embodiments, before obtaining the first audio signal, or after transmitting the first radio frequency signal, it further includes: judging whether to start the remote recording mode or the wired hearing aid mode; if yes, obtaining the second sound signal of the microphone; encoding and decoding the second sound signal in the classic Bluetooth mode or the LE Audio mode to obtain the fourth audio signal; and outputting the fourth audio signal.
[0055] Specifically, when the remote recording mode is started, the second sound signal obtained by the built-in microphone or the external microphone is converted into the fourth audio signal, and the fourth audio signal is output to the smart device, thereby realizing the remote recording effect.
[0056] When the wired hearing aid mode is started, the second sound signal obtained by the built-in microphone or the external microphone is converted into the fourth audio signal, and the fourth audio signal is output to the hearing aid device, thereby improving the high quality of the sound heard by the hearing-impaired person. If the LE Audio mode is used, low-noise, low-delay, and high-fidelity sound can be obtained.
[0057] When applied to the transmitting end, in some embodiments, before obtaining the first audio signal, or after transmitting the first radio frequency signal, it further includes: judging whether to start the wireless hearing aid mode; if yes, obtaining the third sound signal of the microphone; encoding and decoding the third sound signal in the classic Bluetooth mode or the LE Audio mode to obtain the fifth radio frequency signal; and transmitting the fifth radio frequency signal.
[0058] It can be understood that the method can be applied to input audio to the hearing aid device at a long distance, thereby improving the high quality of the sound heard by the hearing-impaired person. If the LE Audio mode is used, low-noise, low-delay, and high-fidelity sound can be obtained.
[0059] Of course, the above local recording mode, remote recording mode, wired hearing aid mode, and wireless hearing aid mode can also be applied to the receiving end, at this time, the above modes occur before the step of receiving the second radio frequency signal, or occur after the step of outputting the second audio signal, and the specific steps are the same, which will not be described here.
[0060] In some embodiments, the step S130 of transmitting the first radio frequency signal can include: in the LE Audio mode, automatically searching for a plurality of LE Audio modes nearby; establishing a broadcast with each of the plurality of LE Audio modes; and transmitting the first radio frequency signal to the plurality of LE Audio modes.
[0061] Specifically, when performing the transmitting action, in the LE Audio mode, other LE Audio modes in the vicinity can be automatically searched, and automatic connection can be achieved without pairing, realizing the broadcast sharing function. Moreover, in the broadcast case, one transmitting end can correspond to one or more receiving ends, and there is no limit to the number of receiving ends, and a large number of connections can be achieved. In addition, through the broadcast, high-resolution lossless format audio can be obtained.
[0062] Of course, the step S140, receiving the second radio frequency signal, can include: in the LE Audio mode, automatically searching for the LE Audio mode in the vicinity; establishing a broadcast with the LE Audio mode in the vicinity; and receiving the second radio frequency signal of the LE Audio mode in the vicinity.
[0063] In addition, in the classic Bluetooth mode, through the interaction of the teaming signal and the radio frequency signal, audio sharing can also be realized.
[0064] In other application scenarios, when the broadcast function is not needed, the broadcast does not need to be established, and the first radio frequency signal can be directly transmitted or the second radio frequency signal can be directly received.
[0065] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiment of the application.
