Embodiment 1

[0026] This embodiment provides a method for controlling audio output, see figure 1 , the method flow includes:

[0027] 101: Detect whether the earphone is in the state of audio output;

[0028] 102: If it is detected that the earphone is in the state of audio output, then identify the current audio output environment;

[0029] 103: Adjust the volume of the audio output according to the identified current audio output environment, determine a preset audio output time, and turn off the audio output after the preset audio output time is reached.

[0030] In one embodiment, detecting whether the earphone is in the state of audio output specifically includes:

[0031] Detect human body information on the earphone, and judge whether the earphone is in the state of audio output according to the detected human body information. The human body information includes at least one or more of body temperature, body pulse and ear pressure.

[0032] In one embodiment, the above-mentioned...

Embodiment 2

[0040] This embodiment provides an audio output control method. The method identifies the current audio output environment, controls the volume of the audio output according to the identified current audio output environment, and turns off the audio output after reaching the preset audio output time. Audio output for hearing protection. For ease of description, this embodiment takes the audio output control device as an example to describe the method provided in this embodiment in detail. see figure 2 , the method flow provided by this embodiment includes:

[0041] 201: Detect whether the earphone is in the state of audio output, if yes, execute step 202, otherwise, the process ends;

[0042] For this step, in practical applications, human body information can be detected on the earphone, and it can be judged whether the earphone is in the state of audio output according to the detected human body information, wherein the human body information includes at least body temper...

Embodiment 3

[0059] see image 3 , this embodiment provides an audio output control device, the control device is used to execute the method operation steps in the first embodiment and the second embodiment above, including: a state detection module 301, a control module 302, an environment recognition module 303 and volume adjustment module 304;

[0060] A state detection module 301, configured to detect whether the earphone is in the state of audio output;

[0061] The control module 302 is used to make the environment recognition module 303 recognize the current audio output environment when the state detection module 301 detects that the earphone is in the state of audio output; according to the current audio output environment recognized by the environment recognition module 303, control the volume adjustment Module 304 adjusts the volume of the audio output, and determines the preset audio output time according to the current audio output environment, and closes the audio output aft...

Abstract

The invention discloses a control method and an apparatus for audio output, which belong to the field of signal processing. The method comprises: detecting whether a headphone is in the output state of audio; and if yes, identifying the present output environment of audio; adjusting the volume of the audio output according to the identified present output environment of audio, determining the output time of audio, and closing the audio output after the predetermined audio output time is achieved. The control apparatus comprises: a state detecting module, a control module, an environment identifying module, and a volume adjusting module. The invention adjusts the volume and determines the predetermined audio output time according to the identified present output environment of audio, and closes the audio output after the predetermined audio output time is achieved, thus the audio output can be effectively controlled, further the problem of hearing damage caused by long time receiving of audio output or high volume voice is solved.

Description

technical field [0001] The invention relates to the field of signal processing, in particular to an audio output control method and device. Background technique [0002] With the improvement of people's living standards and the increasing pressure of work, listening to music or listening to the radio has gradually become the main way for people to relax in their daily lives. Therefore, people have more and more demands for audio output. Audio output control equipment It has also become common in everyday life, for example, earphones and mobile phones. Young people wearing headphones can often be seen in environments such as buses, subways, and noisy streets. However, listening to music or radio with audio output control devices such as earphones for a long time will cause the ears to be exposed to high-intensity noise for a long time, which will cause some people's hearing loss and noise-induced deafness over time. [0003] In order to alleviate various hearing impairments...
