Volume Control Method, Device, and Computer-Stored Readable Storage Medium

Abstract

The invention discloses a volume controlling method and device for a Bluetooth speaker with an externally-connected terminal and computer readable storage media, and belongs to the technical filed of terminals. The method comprises the steps that a pulse code modulation (PCM) audio stream obtained through parsing of audio data to be played is copied to obtain two same PCM audio streams; if it is detected that the Bluetooth is connected, according to volume adjusting instructions, PCM amplitude of one of the PCM audio streams is adjusted, wherein volume of an audio output equipment of the terminal is adjusted based on the other PCM audio stream; the adjusted PCM audio stream is transferred to the externally-connected Bluetooth speaker, so that the externally-connected Bluetooth speaker outputs voice based on the adjusted PCM audio stream. According to the method, through copying of the PCM audio stream on the terminal side, the same two PCM audio streams are obtained, so that the Bluetooth speaker outputs voice directly according to the adjusted PCM audio stream, and the efficiency of volume adjusting is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a volume control method, device, and computer-storage-readable storage medium. Background technique [0002] With the development of technology, when users use terminals such as smart TVs and tablet computers to play audio data, in order to obtain better sound quality experience, they usually play audio data through smart wireless speakers. Remote control function. For example, when the smart wireless speaker is a Bluetooth speaker, the Bluetooth speaker can be paired with a smart TV, that is, the sound of the smart TV is played through the Bluetooth speaker. When the user needs to adjust the volume of the currently playing audio data, it may be inconvenient for the user to adjust the knob on the Bluetooth speaker to control the volume when the distance between the Bluetooth speaker and the user is far. At this time, the user can use the TV remote control to control t...

Problems solved by technology

[0004] However, because the AVRCP protocol version of many Bluetooth speakers on the market is relatively low or does not support the AVRCP protocol, the Bluetooth speakers cannot process the volume adjustment commands sent by the terminal through the AVRCP protocol.

For such a smart wireless speaker, if the user wants to adjust the volume of the audio data played by the Bluetooth speaker, he must manually rotate the button on the Bluetooth speaker to adjust the volume, which brings inconvenience to the user and reduces the efficiency of volume adjustment.

In addition, for such Bluetooth speakers that have a lower version of the AVRCP protocol or do not support the AVRCP protocol, when the volume of the Bluetooth speaker is not adjusted through the AVRCP protocol, but the volume of the audio stream input to the Bluetooth speaker is adjusted on the terminal side, although It is also possible to change the playback volume of the Bluetooth speaker, but it will cause the volume of all audio output ports of the terminal to change accordingly. If the Bluetooth speaker is disconnected from the terminal at this time, the terminal will switch to its own audio output device, for example Speaker, at this time, the user finds that the volume of the audio data output by the terminal's own audio output device also changes at the same time;

[0005] That is to say, when the user wants to adjust the volume of the Bluetooth speaker, if the Bluetooth speaker cannot support the resolution of the volume adjustment command through the AVRCP protocol, the user has to adjust the amplitude of the PCM audio stream on the terminal side, but this adjustment will not only cause The volume of the Bluetooth speaker changes, and the volume of all other audio output ports will change accordingly, that is, the volume of the Bluetooth speaker cannot be processed separately, which affects the user experience
