Embodiment Construction

[0013] see figure 1 Shown is a hardware structure diagram of a preferred embodiment of the system for automatically adjusting the output volume of an electronic device according to the present invention. The system is applied to an electronic device 100, and the electronic device 100 may be a computer, a smart TV, a mobile phone, an MP3 player, or the like. The electronic device 100 includes a control chip 10 , a memory 20 , a sound sensor 30 , a pulse width modulation (Pulse Width Modulation, PWM) unit 40 and a sound output unit 50 . The sound output unit 50 may be a speaker, a sound box, or the like. The components 10-50 of the electronic device communicate via the system bus. The system includes a setting unit 11 , a judgment unit 12 , a calculation unit 13 and an output unit 14 that are solidified in the control chip 10 . Units 11-14 include computerized program instructions.

[0014] The setting unit 11 is for the user to set the correlation between the volume value o...

Abstract

The invention provides a system for automatically regulating output volume of an electronic device. The electronic device comprises a sound sensor, a sound output unit and a PWM unit. The system sets an association relationship between a volume value of the sound output unit and a volume value of a surrounding environment, and sets a maximum volume value that ears can bear; when a user plays audio data, the system calculates the duty ratio of the PWM unit according to an environment volume value detected by the sound sensor, a volume value which is currently outputted by the sound output unit, a volume value which should be outputted by the sound output unit and is determined according to the association relationship, and the set maximum volume value that ears can bear; and the system outputs the duty ratio tot the PWM unit and drives the PWM unit to output corresponding PWM signals to the sound output unit so as to adjust the volume of sound output. The invention also provides a method for automatically regulating the output volume of the electronic device.

Description

technical field [0001] The present invention relates to an electronic device control system and method, in particular to a system and method for automatically adjusting the output volume of an electronic device. Background technique [0002] When users use mobile phones in public places, or watch TV at home, use computers to watch TV, movies, or listen to music, the external ambient sound may change, sometimes noisy, sometimes quiet, in order to achieve satisfactory listening enjoyment, in order to achieve satisfaction The user may need to adjust the volume frequently, which is more troublesome. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a system and method for automatically adjusting the output volume of an electronic device, which can automatically adjust the output volume of the electronic device according to the volume of the environment around the electronic device. [0004] A system for automatically adjusting the output volum...
