Volume adjusting method and system, mobile terminal and playing device

Abstract

The invention discloses a volume adjusting method and system, a mobile terminal and a playing device. The method comprises the steps that: a volume adjusting message is sent to a playing device in a condition that a specified key is pressed and a press-down state is maintained is detected such that the playing device adjusts volume for one time with the interval of a specified time length, when a condition that the specified key is switch to a loose state from the press-down state is detected, and a stop adjustment message is sent to the playing device such that the playing device stops volume adjustment. The mobile terminal sends a volume adjustment message to the playing device to trigger the playing device to adjust the volume for one time with the interval of a specified time length and sends a stop adjustment message to the playing device such that the playing device stops volume adjustment, the sending of a trigger message with the interval of tens of milliseconds by the mobile terminal is not needed, the generation of a large number of trigger messages in a short time can be avoided, the occupation of a network bandwidth is avoided, the burden of network communication transmission is reduced, and communication delay and packet loss are avoided.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a volume adjustment method and system, a mobile terminal and a playback device. Background technique [0002] At present, the user can use the smart phone to control the volume of the speaker. Specifically, an application program (APP) that can control the volume of the speaker can be installed in the smart phone. After the user starts the application in the smart phone and establishes a connection with the speaker, he can Control the volume of the speaker by long pressing the volume key. [0003] Among them, when the user presses the volume button for a long time, the volume change of the speaker is triggered every tens of milliseconds. Every time it is triggered, the smart phone will send a trigger message to the speaker. Adjust its volume once. Therefore, the smartphone will generate a large number of trigger messages in a short period of time, which will occ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a volume adjustment method and system, a mobile terminal and a playback device, aiming to solve the problem of using a smart phone to adjust the volume of a speaker in the prior art because the smart phone will generate a large number of trigger messages in a short period of time. There will be a large amount of network bandwidth occupied, which will bring great pressure to network communication transmission and processing, and will easily cause communication delays and packet loss problems
