Problems solved by technology

However, these technologies cannot guarantee that the output volume of the electronic device is in an appropriate range, let alone effectively deal with the linear change rate of the volume, so it is impossible to provide the most appropriate volume

Embodiment

[0015] FIG. 1 is a schematic block diagram of the basic structure of the volume control system of the present invention. As shown in the figure, the volume control system 10 of the present invention is applied in electronic devices such as mobile phones, televisions or stereos with output audio source signals, and the volume control system includes a setting module 110, a detection module 120, and a judgment module 130 and a control module 140 . In this embodiment, the electronic device is described by taking a television as an example.

[0016] The setting module 110 sets the average output volume of the TV set and the floating value of the output volume, for example, the decibel number of the average output volume is set to 50 decibels, and the floating value of the output volume is set to 5 decibels. In addition, volume parameters such as the average output volume of the TV set and the floating value of the output volume can be uniformly set at the factory. The input meth...

Abstract

Being applicable to electronic equipment with audio output function, the volume control system includes following modules: setting module is in use for setting up volume parameter for the electronic equipment; detecting module is in use for detecting output volume corresponding to the audio received by the electronic equipment; judging module compares the output volume detected by the detecting module with volume parameter setup by the setting module, and sends out an abnormal information if the output volume detected by the detecting module goes beyond the volume parameter; control module controls the electronic equipment to adjust the output volume of the received audio if received the said abnormal information. Based on a preset volume, the invention magnifies or reduces received volume properly so as to control the output volume of the received audio, confine the output volume in a preset bound, and provide moderate volume for user.

Description

technical field [0001] The present invention relates to a volume control system and method, in particular to a volume control system and method applied in an electronic device with audio output function and capable of controlling the output volume. Background technique [0002] Traditional electronic devices with audio output function, such as televisions and telephones, are quite popular electronic devices, and the ability to provide ideal sound effects is the most basic requirement of these electronic devices. And with the development and progress of digital technology, such electronic devices play an increasingly important role in people's daily life. [0003] The volume control processing of traditional electronic devices is realized by simulation technology, and its sound control is adjusted through manual operation switches, and users can set the volume according to their needs. This volume control method has disadvantages that cannot be ignored. For example, when the...
