Description

A method, system and earphone for intelligently controlling multimedia playback

technical field

The invention relates to a multimedia playing technology of a mobile terminal, in particular to a method, a system and an earphone for intelligently controlling multimedia playing.

Background technique

With the popularity of mobile terminals, mobile phones are no longer just a single communication tool. Multimedia applications have become an integral part of mobile phones. People listening to music on mobile phones can be seen everywhere. People have a private space. Many mobile phone users who have poor sleep quality and are easily disturbed by external noise will choose to listen to music with headphones to help them fall asleep. However, after falling asleep, the mobile phone will not stop working, and the music will not stop playing. This reduces the standby time of the mobile phone. More importantly, listening to music with earphones for a long time will damage the user's eardrum. The injury can be described as the best of both worlds.

A sensor is a physical device or biological organ that can detect and sense external signals, physical conditions (such as light, heat, humidity) or chemical composition (such as smoke), and transmit the detected information to other devices or organs. A device or device that is specified to be measured and converted into a usable signal according to a certain rule, usually composed of a sensitive element and a conversion element. The sensor is to sense the measured information and transform it into an electrical signal or other required form of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. It is to realize automatic detection and automatic detection. The primary link of control.

The patent application number CN200710200453.9 discloses an audio device, including a playback device and earphones. The headset includes a position sensor for sensing changes in the position of the headset. The playback device includes a position processing module, a control module and a power management module. The position processing module receives the sensing signal output by the position sensor and calculates the position change amount of the earphone according to the sensing signal. The control module controls the power management module according to the position change of the earphone so that the power management module stops supplying power to the audio device. The audio device senses the position change of the earphone through the position sensor, and the position processing module calculates the position change of the earphone according to the sensing signal. After the user enters the sleep state, the control module can automatically turn off the audio device according to the position change of the earphone, so that the The automatic shut-off function is more user-friendly. However, this method of using a position sensor to automatically turn off the audio device must only be able to turn off the audio device when the user's activity causes the position of the earphone to change, which is not accurate enough.

The invention patent with the publication number US5146501 discloses a headset that adjusts the volume by detecting the movement of the dancer's head through a posture-sensitive potentiometer. This headset cannot automatically turn off the audio device after the user enters a sleep state, nor can it reduce the Ear damage caused by listening to music during sleep.

Detailed ways

The basic idea of the present invention is: a sensor for detecting the pulse is set on the earphone, and the sensor generates a signal every time a pulse is detected and transmits it to the mobile terminal; the sleep mode option is set on the mobile terminal, and when the sleep mode is selected, the mobile terminal According to the number of pulses detected by the sensor per unit time, the user's real-time heart rate is obtained, and after the user enters the sleep state according to the heart rate change before and after the user's sleep, control the multimedia playback of the user;

The mobile terminal includes mobile phone, MP4, notebook computer, etc.; the multimedia playback includes audio and/or video playback.

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

A kind of method for intelligently controlling multimedia playback provided by the present invention, as shown in Figure 1, the method comprises the following steps:

Step 101: setting a pulse detection sensor on the earphone, the sensor generates a signal every time a pulse is detected and transmits it to the mobile terminal;

Specifically, a sensor for detecting the pulse is set in the earphone to measure the pulse at the user's ear. Since the pulse at the ear is generally slight, in order to allow the sensor to obtain pulse information more accurately, the sensor can be set near the user's ear. Where the pulse is strong, such as behind the auricle, etc., in addition, a fixing device can be added so that the sensor can always be in contact with the pulse at the ear; when the sensor is working, a signal is generated every time a pulse is detected, and the The signal is transmitted to the mobile terminal; the transmission of the signal to the mobile terminal generally means transmitting the signal to the mobile terminal through a signal line.

Step 102: Set the sleep mode option on the mobile terminal. When the sleep mode is selected, the mobile terminal obtains the real-time heart rate of the user according to the number of pulses detected by the sensor per unit time;

Specifically, the sleep mode option is set on the UI of the mobile terminal. When the user selects the sleep mode, the mobile terminal will generate an interrupt every time a signal sent by the sensor is detected, and the counting process will be performed in the interrupt processing, that is, the counter will add 1. Count the number of signals transmitted by the sensor per unit time to obtain the real-time heart rate of the user, and perform the counting process again each time the statistics are performed, that is, the counter is reset to zero; the unit time can be 20 seconds, 30 seconds or 1 minute wait;

This step further includes: setting a healthy mode option on the UI of the mobile terminal, when the user selects the healthy mode, the mobile terminal obtains the real-time heart rate of the user according to the number of pulses detected by the sensor per unit time;

In the above, the signal sent by the mobile terminal detection sensor can be detected by the earphone button detection circuit or a dedicated signal detection circuit. The dedicated signal detection circuit is a detection circuit specially set for the signal sent by the sensor. This detection signal circuit belongs to the prior art, and will not be repeated here; when the signal sent by the sensor is detected by the earphone button detection circuit, it can first be judged whether it is a sleep mode or a healthy mode, and when it is a sleep mode or a healthy mode, Switch the normal earphone button interrupt processing to the above counting processing; when not in sleep mode or healthy mode, the interrupt processing generated by the button detection circuit is switched back to the normal earphone button interrupt processing;

Step 103: When the sleep mode is selected, the mobile terminal controls its own multimedia playback after determining that the user enters the sleep state according to the heart rate changes before and after the user's sleep;

Specifically, according to the real-time heart rate obtained by the mobile terminal before and after the user's sleep, the user sets the threshold of the heart rate change before and after the user's sleep on the mobile terminal. Real-time heart rate is compared, and when it is greater than the threshold, it is considered that the user enters a sleep state, and the current multimedia playback is stopped;

According to the real-time heart rate obtained by the mobile terminal before and after the user's sleep, the user sets the threshold of the heart rate change before and after the user's sleep on the mobile terminal, generally: the mobile terminal records the real-time heart rate obtained each time before and after the user's sleep, and the user searches for the recorded heart rate of the mobile terminal. Real-time heart rate determines the threshold of heart rate changes before and after sleep;

This step further includes: setting a threshold setting option on the UI of the mobile terminal, when the user selects the threshold setting, providing a threshold setting interface for inputting the threshold of the user's heart rate change before and after sleep;
