Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
Fig. 1 is a schematic view of an application environment of an audio information obtaining method according to an embodiment of the present invention. The singing apparatus 100 comprises a bluetooth module 110, the singing apparatus 100 is in communication connection with the intelligent terminal device 200 through the bluetooth module 110, at least one piece of singing software is installed in the intelligent terminal device 200, and the at least one piece of singing software can perform data communication and interaction with the bluetooth module 110 through the intelligent terminal device 200.
In this embodiment, a plurality of bluetooth protocols are stored in the bluetooth module 110, and the plurality of bluetooth protocols include A2DP (Advanced Audio Distribution Profile), HFP (handles-freeProfile), HSP (HeadsetPro-Profile), and AVRCP (Audio/video remote Control Profile).
In this embodiment, the singing software may be a singing bar, a national karaoke, and the like, the first bluetooth module 110 may be a single mode or a dual mode, and the intelligent terminal device 200 may be, but is not limited to, a desktop computer, a notebook computer, a tablet computer, an android phone, or an IOS phone.
Fig. 2 is a flowchart illustrating an audio information obtaining method according to an embodiment of the present invention. It should be noted that the audio information obtaining method according to the embodiment of the present invention is not limited by the specific sequence shown in fig. 2 and described below, and it should be understood that, in other embodiments, the sequence of some steps in the audio information obtaining method according to the embodiment of the present invention may be interchanged according to actual needs, or some steps in the audio information obtaining method may be omitted or deleted. The audio information obtaining method can be applied to the bluetooth module 110, and the specific process shown in fig. 2 will be described in detail below.
In step S101, the bluetooth module 110 receives audio information to be analyzed, which is sent by any piece of singing software installed on the intelligent terminal device 200.
For example, after the intelligent terminal device 200 and the singing apparatus 100 are connected in a bluetooth pairing manner, the singing software installed on the intelligent terminal device 200 can transmit the audio information to be analyzed to the bluetooth module 110 through the intelligent terminal device 200. The audio information to be analyzed supports which bluetooth protocol transmission is compiled by the singing software, and the intelligent terminal device 200 transmits the audio information to be analyzed to the bluetooth module 110 according to the currently supported bluetooth protocol.
Step S102, the bluetooth module 110 detects a bluetooth protocol supported by the audio information to be analyzed, and obtains a detection result.
In this embodiment, when the bluetooth module 110 receives the audio information to be analyzed, it detects which bluetooth protocol transmission it supports, and obtains a detection result. For example, the detection result may support only the A2DP bluetooth protocol transmission, only the HFP bluetooth protocol transmission, simultaneously support the A2DP bluetooth protocol and the HFP bluetooth protocol transmission, and the like for the audio information to be parsed.
Step S103, the bluetooth module 110 determines a target bluetooth protocol from the multiple bluetooth protocols according to the detection result, and analyzes the audio information to be analyzed by using the target bluetooth protocol to obtain the analyzed audio information.
In this embodiment, when the detection result indicates that the audio information to be analyzed only supports one of the bluetooth protocols, the bluetooth module 110 determines the one of the bluetooth protocols as the target bluetooth protocol; when the detection result indicates that the audio information to be analyzed simultaneously supports at least two bluetooth protocols of the plurality of bluetooth protocols, the bluetooth module 110 determines a bluetooth protocol with the highest priority of the at least two bluetooth protocols as the target bluetooth protocol.
In this embodiment, after the bluetooth module 110 determines the target bluetooth protocol according to the detection result, the bluetooth module 110 and the singing software may perform data transmission using the target bluetooth protocol.
The plurality of bluetooth protocols may be prioritized when setting the bluetooth protocols supported by the bluetooth module 110, for example, the priority of the A2DP bluetooth protocol is greater than that of the HFP bluetooth protocol because the A2DP bluetooth protocol satisfies 320kb/s transmission, which is a high quality music transmission, and the HFP bluetooth protocol is only 8 kb/s; when the audio information to be analyzed only supports the A2DP bluetooth protocol or only supports the HFP bluetooth protocol for transmission, the bluetooth module 110 analyzes the audio information by using the corresponding A2DP bluetooth protocol or HFP bluetooth protocol; when the audio information to be analyzed simultaneously supports two bluetooth protocols, i.e., A2DP and HFP, the bluetooth module 110 analyzes the audio information by using the A2DP bluetooth protocol with higher priority.
It can be understood that, in this embodiment, after the performing apparatus 100 performs bluetooth pairing with the intelligent terminal device 200 through the bluetooth module 110, data is transmitted between the performing apparatus 100 and the intelligent terminal device 200 by using a peer-to-peer protocol, that is, only when the bluetooth protocol supported by the singing software on the bluetooth module 110 and the intelligent terminal device 200 is the same, the bluetooth module 110 can analyze audio information output by the singing software, so as to implement data transmission between the bluetooth module 110 and the singing software. In the present application, since the underlying protocol of the bluetooth module 110 in the singing apparatus 100 has been modified in advance, the bluetooth module 110 can support multiple bluetooth protocols for data transmission, so that no matter which bluetooth protocol is supported by the singing software, the bluetooth module 110 can select the bluetooth protocol identical to that of the singing software from the multiple bluetooth protocols, and thus data communication between the bluetooth module 110 and the singing software is realized under the same protocol architecture.
