Detailed Description
In order to make the above objects, features and advantages of the present application more comprehensible, the following description will make the technical solutions of the embodiments of the present application clear and complete with reference to the accompanying drawings of the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, based on the embodiments herein, which are within the scope of the protection of the present application, will be within the purview of one of ordinary skill in the art without the exercise of inventive faculty.
Example 1
An embodiment of the present application provides a broadcast audio playing method, in a first embodiment of the broadcast audio playing method of the present application, referring to fig. 1, the broadcast audio playing method is applied to a wireless earphone, and the broadcast audio playing method includes:
step S10, scanning the current environment to obtain broadcast synchronous information of at least one broadcast audio source in the current environment;
step S20, voice broadcasting is carried out according to each piece of broadcasting synchronous information, and touch operation instructions aiming at each piece of broadcasting synchronous information are obtained;
step S30, determining a target broadcast audio source according to the touch operation instruction, and synchronizing with the target broadcast audio source;
Step S40, receiving the digital audio stream of the target broadcast audio source and playing the sound signal corresponding to the digital audio stream.
In this embodiment, it should be noted that the broadcast audio playing method is applied to a wireless earphone, and the wireless earphone may be a wireless headset, an in-ear TWS earphone, a half-in-ear TWS earphone, or the like. It will be appreciated that the wireless headset is typically not provided with a display screen.
In addition, it should be noted that the broadcast audio source is an audio transmitting device that broadcasts to the outside based on the Auracast technology, such as a computer, a smart phone, a television, and the like. The broadcast synchronization information may include information of a broadcast name, broadcast content, broadcast configuration, transmission parameters, etc. of the broadcast audio source.
Illustratively, steps S10 through S40 include: and scanning the current environment through the Bluetooth module of the wireless earphone to obtain the broadcast synchronization information of at least one broadcast audio source in the current environment. Therefore, the information such as the broadcast name, broadcast content, broadcast configuration, transmission parameters and the like of each broadcast audio source in the current environment can be determined. The preset triggering operation can be to double-click a pairing key of the earphone box after opening a box cover of the earphone box, so that the scanning of the current environment is triggered, or the pairing key of the earphone box is pressed for a long time, and the preset triggering operation can be set according to specific requirements. Then, the text content of each piece of broadcast synchronization information can be converted into voice content according to a preset ordering mode (such as the order of signal intensity, the arrangement order of first letters of broadcast names and the like), and voice broadcasting is performed according to the order of the preset ordering mode, so that a user can listen to the broadcast synchronization information corresponding to each broadcast audio source. For example, after broadcasting one broadcast synchronization information in the order of the preset ordering manner, a touch operation instruction of the user for the broadcast synchronization information currently broadcasted may be obtained. When the touch operation instruction is a switching instruction, the currently broadcasted broadcast synchronization information may be switched, for example, to the next broadcast synchronization information or the last broadcast synchronization information in the broadcast synchronization information. And further, under the condition that the touch operation instruction is a selection instruction, taking the broadcast audio source corresponding to the broadcast synchronization information which is currently broadcast as a target broadcast audio source, so as to determine the target broadcast audio source which the user expects to listen to. Thus, the target broadcast audio source can be synchronized according to the information such as broadcast configuration, transmission parameters and the like in the broadcast synchronization information of the target broadcast audio source. Thus, after synchronizing with the target broadcast audio source, the digital audio stream of the target broadcast audio source is received, and a sound signal corresponding to the digital audio stream is played.
In another embodiment, the steps S10 to S40 include: and scanning the current environment through the Bluetooth module of the wireless earphone to obtain the broadcast synchronization information of at least one broadcast audio source in the current environment.

Then, the text content of each broadcast synchronous information can be converted into voice content to be broadcasted one by one, so that a user can hear the broadcast synchronous information corresponding to each broadcast audio source. For example, the broadcast name and the broadcast content in the broadcast synchronization information of each broadcast audio source may be sequentially voice-broadcasted at preset interval durations (such as 2s, 3s, etc.). And then the user can perform touch operation on the broadcasting synchronous information currently being subjected to voice broadcasting, so that the wireless earphone acquires a touch operation instruction on the broadcasting synchronous information. And further, under the condition that the touch operation instruction is a selection instruction, taking the broadcast audio source corresponding to the broadcast synchronous information which is currently in voice broadcasting as a target broadcast audio source, thereby determining the target broadcast audio source which the user expects to listen to. Thus, the target broadcast audio source can be synchronized according to the information such as broadcast configuration, transmission parameters and the like in the broadcast synchronization information of the target broadcast audio source. Thus, after synchronizing with the target broadcast audio source, the digital audio stream of the target broadcast audio source is received, and a sound signal corresponding to the digital audio stream is played.

Thus, illustratively, steps S11 through S12 include: the first protocol data unit of the extended broadcast may be received on the main broadcast channel of the extended broadcast using a main broadcast access address corresponding to the main broadcast channel specified in the bluetooth core specification.

For example, it may be determined whether the user operation action represented by the touch operation information is a single click, a double click or a triple click by the number of clicks within a preset duration threshold (e.g., 1s, 2s, etc.) in the touch operation information. And then according to the user operation action represented by the touch operation information, inquiring a mapping table of preset user operation actions and touch operation instructions, and determining the touch operation instruction corresponding to the touch operation information.
