In order to improve the problem that the conventional microphone is difficult to operate and can not be used for a long time, the present invention proposes a broadcasting system, a sound transmitting device thereof and a control method of the electronic device, thereby intelligently controlling the electronic device according to the operating situation, which is not only convenient for the user to control. It is also possible to save energy to extend the use time of the electronic device, as detailed below.

FIG. 2 is a block diagram showing the circuit of a sound transmitting device 200 according to an embodiment of the present invention. In the present embodiment, the technical means for the sound-transmitting device 200 to be intelligently manipulated and saved is first illustrated. As shown, the sound-transmitting device 200 includes the first sensor 220, the second sensor 230, and processing. 260. In the connection relationship, the first sensor 220 and the second sensor 230 are respectively coupled to the processor 260. However, the first sensor 220 and the second sensor 230 may be connected in series and then recoupled. Connected to the processor 260, depending on actual needs. It should be noted that the sound transmitting device 200 can be, but not limited to, a microphone. Any electronic device capable of transmitting sound, such as a mobile phone, a tablet computer, a wireless walkie-talkie, etc., is within the scope of the present disclosure.

Referring to FIG. 2, the first sensor 220 senses the first parameter value of the sound transmitting device 200 for comparison with the first threshold. For example, the first sensor 220 can be, but is not limited to, an acceleration sensor for sensing the acceleration value of the sounding device 200 to compare with a preset acceleration threshold, and determining whether to turn on the second sensor. 230. Additionally, the second sensor 230 senses the second parameter value for comparison with the second threshold. For example, the second sensor 230 can be, but is not limited to, a gyroscope that senses the angle value of the sounding device 200 to compare with a preset angle threshold to determine whether to turn on the sounding device 200.

The power consumption of the first sensor 220 is lower than the power consumption of the second sensor 230. For example, the power consumption of the acceleration sensor is lower than the power consumption of the gyroscope. However, the present invention is not limited to the above embodiment, and the first sensor is not limited to the above embodiment. The 220 and the second sensor 230 can be selected according to requirements, and the first sensor 220 and the second sensor 230 can selectively use an acceleration sensor, a vibration sensor, a gyroscope, etc. The sensor is implemented as long as the power consumption of the first inductor 220 is lower than the power consumption of the second inductor 230. The effect that can be achieved by using the above-described component power consumption differential configuration method will be described in detail later.

Moreover, the processor 260 turns on the second sensor 230 when the first parameter value is greater than the first threshold, and controls to turn on the sounding device 200 when the second parameter value is greater than the second threshold. For example, when the acceleration value sensed by the first sensor 220 is greater than the acceleration threshold, the processor 260 turns on the second sensor 230. In addition, when the angle value sensed by the second sensor 230 is greater than the angle threshold, the processor 260 controls to turn on the sound transmitting device 200. In detail, the microphone 210, the screen 240, and the wireless transmitting mode of the sound transmitting device 200 are turned on. The components such as the group 250 are allowed to operate the sound transmitting device 200 for the user to perform speeches, sings, and the like.

With the above control method, when the user picks up the sound transmitting device 200 from the flat table, the first sensor 220 of the sound transmitting device 200 senses an acceleration value once the value exceeds the preset acceleration valve. The value is then turned on by the processor 260 to the second sensor 230. Subsequently, if the user wants to use the sound transmitting device 200, generally, the user holds the sound transmitting device 200 in a manner that is nearly perpendicular to the ground, so that the user picks up the sound transmitting device 200 and turns on the second sensor. After the 230, the second sensor 230 of the sounding device 200 senses an angle value between the sound transmitting device 200 and the ground. Once the value exceeds the preset angle threshold, the sounding device 200 is turned on by the processor 260. For the user to speak, sing, etc.

In this way, the user does not need to manually turn the microphone on or off as in the prior art, but the present invention intelligently controls the sound transmitting device 200 according to the operating situation, which is convenient for the user to control. Moreover, since the power consumption of the first sensor 220 is smaller than that of the second sensor 230, the first sensor 220 with low power consumption can make a preliminary judgment on the operating situation, and according to the judgment result, it is determined whether to turn on the sensing. The sensitive but relatively energy-consuming second sensor 230 opens the sound-transmitting device 200 with precise sensing of the operating situation for energy saving purposes. Further, if the low-power first sensor 220 determines that the operating situation does not match after the initial judgment, the second inductor 230 with high power consumption is not turned on, thereby achieving the purpose of energy saving, and prolonging the sound transmitting device. 200 usage time.

Continuing to refer to FIG. 2, in an embodiment, the sounding device 200 further includes a power source 270. The power supply 270 is coupled to the processor 260 in a connection relationship. In operation relationship, the power supply 270 provides power to the first sensor 220, the second sensor 230, and the processor 260, and respectively turns on or off the power supply to each of the sensors 220, 230 according to the control of the processor 260.

In another embodiment, the sounding device 200 further includes a detector 280. In the connection relationship, the detector 280 is coupled to the power source 270 and configured to detect whether the sound transmitting device 200 is coupled to an external device. If the sound transmitting device 200 is coupled to the external device, the detector 280 outputs a shutdown signal to the power source 270, and then the power source 270 is turned off according to the shutdown signal. For example, the external device may be, but not limited to, a storage box, a charging stand, etc., when the sound transmitting device 200 is returned to the external device by the user, the detector 280 detects the sound transmitting device 200 through the pin 290. When coupled to an external device, at this time, the detector 280 transmits a shutdown signal to the power source 270 to turn off the power source 270, thereby turning off the sounding device 200. Further, the power source 270 is used to provide power to the various components of the sound transmitting device 200. Therefore, if the power supply 270 of the sound transmitting device 200 is turned off to supply power, all components of the sound transmitting device 200 can be turned off.

However, the present invention is not limited to the embodiment shown in FIG. 2. In another embodiment, the detector 280 does not detect the coupling state of the sound transmitting device 200 and the external device through the pin 290. The detector The 280 can be implemented using a magnetic switch. In this embodiment, if the sound transmitting device 200 is coupled to the external device, the magnetic switch generates an induction to turn off the power source 270, thereby turning off all components of the sound transmitting device 200. As described above, the sound transmitting device 200 of the present invention can be intelligently turned on according to the use situation, without requiring the user to turn off the sound transmitting device 200 by itself, which is convenient for the user to manipulate.

In an embodiment, the power source 270 can include, but is not limited to, a battery and power converter that is powered by a battery that is then converted by the power converter to provide appropriate power to the various components of the sounding device 200. In another embodiment, the power source 270 can include a plurality of power converters coupled to respective components of the sounding device 200 to provide the required power. In yet another embodiment, the power converter described above can be, but is not limited to, a linear regulator (LDO). Since the power supply 270 can be used to provide power to each component individually, when the processor 260 wants to turn off the components of the sounding device 200, the processor 260 can output a corresponding shutdown signal to the power source 270, and the power source 270 can follow the shutdown signal. Power is turned off to the component to turn it off. For example, when the processor 260 wants to turn off the first sensor 220 of the sounding device 200, the processor 260 may output a corresponding shutdown signal to the power source 270, and the power source 270 may stop supplying power to the first sensor 220 according to the shutdown signal. The first sensor 220 is turned off. However, the present invention is not limited to the above embodiments, and the internal structure of the power source 270 can be configured according to actual needs.

In still another embodiment, if the angle value sensed by the second sensor 230 is not greater than the angle threshold, the processor 260 controls to turn off the sounding device 200. For example, if the user picks up the sound transmitting device 200 from the flat surface, the second sensor 230 is turned on when the acceleration value sensed by the first sensor 220 is greater than the acceleration threshold. . However, the user may put the sound-transmitting device 200 back on the table according to the actual situation. For example, when the user suddenly needs to take a speech, and the user finds that his or her clothes are not uniform and needs to organize the appearance or the rest of the situation, it is possible. The sound device 200 is placed back on the table. At this time, the angle value sensed by the second sensor 230 is not greater than the angle threshold, and the sound device 200 is not turned on for the purpose of intelligent control and energy saving.

In still another embodiment, if the angle value sensed by the second sensor 230 is not greater than the angle threshold, the processor 260 determines whether the amount of change of the angle value within a delay time is greater than the angle variation threshold. For example, if the user picks up the sound transmitting device 200 from the flat on the table, the second sensor 230 is turned on. At this time, if the angle value between the sound transmitting device 200 and the ground is not greater than the angle threshold, the cause of the problem is excessive. For example, it is not appropriate to turn off the sound transmitting device 200. The above causes are analyzed. First, it may be that after the user picks up the sound transmitting device 200, the user is called by someone else to talk or the rest of the situation, so that the user does not immediately take the sounding device 200 to the mouth for a speech, Singing...etc., but holding the sounding device 200 but only hanging on the thigh. Second, it is possible that the user puts the sound transmitting device 200 back on the table again.

According to the above causes, different control methods should be adaptively performed. The difference between the above two causes is "whether there is an angular change". As shown in the first reason, if the user continues to hold the sound transmitting device 200, the hand holding the sound transmitting device 200 is somewhat shaken to the sound transmitting device 200 based on the operational characteristics of the human body, and therefore, there is an amount of angular change. On the other hand, as shown in the cause 2, if the sound transmitting device 200 is placed back on the table, there is no angular change. Accordingly, if the angle value sensed by the second sensor 230 is not greater than the angle threshold, the processor 260 determines whether the amount of variation of the angle value within a delay time (eg, 10 seconds) is greater than the angle variation threshold. If the angle value change amount is greater than the angle change amount threshold, it means that the user continuously holds the sound transmitting device 200 and the hand is shaken. At this time, the user is more likely to continue using the sound transmitting device 200, and therefore, the judgment needs to be performed again. Whether the angle value sensed by the second sensor 230 is greater than the operation of the angle threshold is controlled according to the judgment result. On the other hand, if the amount of change in the angle value is not greater than the threshold value of the angle fluctuation amount, it means that the user puts the sound transmitting device 200 back on the table, and at this time, the sound transmitting device 200 needs to be turned off.

In another embodiment, in a state where the sound transmitting device 200 is turned on, when the second parameter value sensed by the second sensor 230 is greater than the third threshold, the second sensor 230 is controlled to be turned off. For example, if the user continues to hold the sounding device 200 for speech, singing, etc., indicating that the user wants to continue using the sound transmitting device 200, the user will hold the transmission in a manner that is nearly perpendicular to the ground. The acoustic device 200, therefore, sets the third threshold to, but not limited to, about 80 degrees. Once a delay time elapses, the angle value sensed by the second sensor 230 is greater than the third threshold (eg, about 80 degrees). , indicating that the user really wants to continue to use the sound transmitting device 200. At this time, the second sensor 230 is not required to turn on or off the sound transmitting device 200. Therefore, the processor 260 controls to turn off the second sensor 230 to save energy. The purpose.

In other embodiments, the second sensor 230 can be, but is not limited to, a composite inductor that can simultaneously sense different types of parameters. Therefore, the second parameter value can include, but is not limited to, the sustaining time of the sounding device 200. The third threshold may be, but is not limited to, a time threshold. The processor 260 controls to turn off the second sensor 230 when the hold-on time (eg, the sound-transmitting device 200 is continuously turned on for 5 minutes) is greater than the time threshold (eg, the time threshold is 3 minutes). In this way, when the user continues to hold the sounding device 200 for speech, singing, etc., the user wants to continue using the sound transmitting device 200, and at this time, the second sensor 230 is not required to be turned on or off. The sound transmitting device 200, therefore, the second sensor 230 is turned off by the above operation for the purpose of energy saving.

In another embodiment, the sounding device 200 further includes a third inductor (not shown) to sense the third parameter value of the sound transmitting device 200. This third sensor can be turned on when the sound transmitting device 200 is turned on. The third sensor may be, but not limited to, a timer. Accordingly, the third parameter value sensed by the third sensor may be, but is not limited to, the sustaining time of the sound transmitting device 200. In addition, the third threshold may be Not limited to the time threshold. When the maintenance on time (eg, the sounding device 200 is continuously turned on for 5 minutes) is greater than the time threshold (eg, the time threshold is 3 minutes), the processor 260 simultaneously turns off the second sensor 230 and the third sensor. In this way, when the user continues to hold the sounding device 200 for speech, singing, etc., indicating that the user wants to continue using the sound transmitting device 200, at this time, the second sensor 230 or the third sensor is not required. In order to sense the state of the sound transmitting device 200, the second sensor 230 and the third inductor (not shown) are turned off by the above operation for the purpose of energy saving.

In an embodiment, the power consumption of the second sensor 230 and the third sensor (not shown) is greater than that of the first sensor 220. Therefore, the first sensor 220 of the low power consumption can be used to operate the situation. Making a preliminary judgment, and determining whether to activate the second sensor 230 that is more sensitive but more energy-consuming according to the judgment result, to accurately sense the operation situation to turn on the sounding device 200 and the third sensor (not shown), The third sensor can further sense the operating situation to simultaneously or sequentially turn off the more energy-consuming second sensor 230 and the third sensor, thereby achieving energy saving. In another embodiment, the power consumption of the second inductor 230 is greater than that of the first inductor 220, and the power consumption of the third inductor is greater than the second inductor 230. Therefore, the first sensor 220 of the low power consumption can make a preliminary judgment on the operating situation to determine whether to turn on the second sensor 230 that is more sensitive but more energy-consuming, and then accurately sensed by the second sensor 230. Operating the situation to turn on the sounding device 200 and the third sensor, and then further sensing the operating situation by the third sensor with high energy consumption but excellent precision to simultaneously or sequentially close the second sensor 230 and the third sensor In this way, according to the operating situation, the sensor with more precise sensing is turned on step by step, and the energy consumption and the precision can be balanced to achieve excellent energy saving effect.

In still another embodiment, various states of the sound transmitting device 200 can be presented on the screen 240 so that the user can understand the state thereof, such as: the power state of the sound transmitting device 200, the opening of each sensor of the sound transmitting device 200, or Close status...etc.

FIG. 3 is a flow chart showing a control method 300 of an electronic device according to still another embodiment of the present invention. The above control method 300 can be used to control various electronic devices having at least two sensors, and the power consumption of each sensor is different. For convenience of explanation, the first inductor and the second inductor are exemplarily illustrated herein, and the power consumption of the first inductor is lower than the power consumption of the second inductor.

The above control method 300 of the electronic device includes the following processes:

Sensing the first parameter value by the first sensor;

Comparing the first parameter value with the first threshold to determine whether to turn on the second inductor;

When the second sensor is turned on, the second parameter is sensed by the second sensor;

The second parameter value and the second threshold are compared to determine whether to turn on the electronic device.

In order to make the above process understandable, please refer to Figure 2 and Figure 3 together. It should be noted that the electronic device may be, but not limited to, various electronic devices including sensors and radios, such as mobile phones, tablet computers, etc., and is not limited to the sound transmitting device 200 shown in FIG. Here, the first sensor 220 of the electronic device is preset to be in an on state, and therefore, the first parameter value can be sensed by the first sensor 220. In step 310, the first parameter value is compared with the first threshold to determine whether to turn on the second sensor. For example, the processor 260 determines whether the first parameter value is greater than the first threshold, and determines the first When the parameter value is greater than the first threshold, step 312 is performed, and the second inductor 230 is turned on by the processor 260. In step 312, the second sensor 230 has been turned on, so that the second parameter value is sensed by the second sensor 230. In step 320, the second parameter value and the second threshold are compared to determine whether to turn on the electronic device. For example, the processor 260 determines whether the second parameter value is greater than the second threshold, and determines the second parameter value. When the value is greater than the second threshold, step 322 is executed, and the electronic device is turned on by the processor 260 to cause the electronic device to be in an on state.

For example, the first sensor 220 can be, but is not limited to, an acceleration sensor for sensing an acceleration value of the electronic device, and the first threshold can be, but not limited to, an acceleration threshold. In step 310, the second inductor 230 can be turned on when the acceleration value sensed by the processor 260 at the first sensor 220 is greater than the acceleration threshold. In step 312, for example, the second sensor 230 can be, but is not limited to, a gyroscope for sensing an angle value of the electronic device. The second threshold value can be, but is not limited to, an angle threshold. For example, the second sensor 230 can be a gyroscope, a timer or other type of sensor. Accordingly, the second parameter value induced by the second sensor 230 can have multiple types of parameter information, such as an angle value, an angular change amount, Time value or other type parameter information. In step 322, when the angle value sensed by the processor 260 on the second sensor 230 is greater than the angle threshold, the electronic device is controlled to be turned on to cause the electronic device to be in an on state.

With the control method 300 of the electronic device, when the user picks up the electronic device from the flat on the desktop, the first sensor 220 of the electronic device senses an acceleration value once the value exceeds the preset acceleration valve. The value is then turned on by the processor 260 to the second sensor 230. Then, if the user wants to use the electronic device, the user will pick up the electronic device and have an angle with the ground. Therefore, after the user picks up the electronic device and turns on the second sensor 230, the electronic device The second sensor 230 senses an angle between the electronic device and the ground. Once the value exceeds the preset angle threshold, the processor 260 turns on the electronic device for the user to operate.

In this way, the user does not need to manually turn on or off the electronic device, but the case intelligently controls the electronic device according to the operating situation, which is convenient for the user to control. Moreover, since the power consumption of the first sensor 220 is smaller than that of the second sensor 230, the first sensor 220 with low power consumption can make a preliminary judgment on the operating situation, and according to the judgment result, it is determined whether to turn on the sensing. The sensitive but relatively energy-consuming second sensor 230 opens the electronic device with precise sensing of the operating situation for energy saving purposes. Further, if the low-power first sensor 220 determines that the operating situation does not match after the initial judgment, the high-power second sensor 230 is not turned on, thereby achieving the purpose of energy saving, thereby prolonging the use of the electronic device. time.

In another embodiment, if it is determined in step 310 that the first parameter value is not greater than the first threshold, then the process proceeds to step 310 to continue to determine by the processor 260 whether the first parameter value is greater than the first threshold. Thereby determining whether to open the second sensor 230.

In still another embodiment, if it is determined in step 320 that the second parameter value is not greater than the second threshold, step 340 is performed, and the processor 260 determines whether the second parameter value is greater than the first time in a delay time. Four thresholds. For example, if the user picks up the electronic device (eg, the sound transmitting device 200) from the flat on the table, the second sensor 230 is turned on. At this time, if the angle between the electronic device and the ground is not greater than the angle threshold, there are many reasons for this. For example, it is not appropriate to turn off the electronic device. Accordingly, if the angle value sensed by the second sensor 230 is not greater than the angle threshold, step 340 is executed, and the processor 260 determines whether the amount of change of the angle value within a delay time is greater than the angle variation threshold.

If the angle value change amount is greater than the angle change amount threshold, it means that the user continues to hold the sound absorbing device 200 and the hand is shaken. At this time, the user is more likely to continue using the electronic device. Therefore, step 320 needs to be performed again. It is determined whether the angle value sensed by the second inductor 230 is greater than the angle threshold, and is controlled according to the judgment result. On the other hand, if the angle value change amount is not greater than the angle change amount threshold, it means that the user puts the electronic device back on the table. At this time, step 342 is performed. In step 342, if the electronic device has not been turned on, the electronic device is maintained in the original closed state, such as the microphone 210, the screen 240, the wireless transmission module 250, and the like of the sound transmitting device 200 shown in FIG. The original closed state is maintained to cause the sound transmitting device 200 to be in a closed state. On the other hand, if the electronic device has been turned on, the electronic device is turned off, such as turning off the sound collector 210 and the screen of the sound transmitting device 200 shown in FIG. 240, a wireless transmission module 250, etc., to turn off the sound transmitting device 200, so that the sound transmitting device 200 is in a closed state. Subsequently, the second inductor 230 is turned off in step 332.

In still another embodiment, the control method 300 further includes a step 330 of determining whether the second parameter value is greater than a third threshold. Referring to FIG. 2 and FIG. 3 together, when the electronic device (eg, the sound transmitting device 200) is turned on, when the second parameter value sensed by the second sensor 230 is greater than the third threshold, the execution is performed. Step 332 is to close the second inductor 230. For example, if the user continues to hold the sounding device 200 for speech, singing, etc., indicating that the user wants to continue using the sound transmitting device 200, the user will hold the transmission in a manner that is nearly perpendicular to the ground. The acoustic device 200, therefore, sets the third threshold to, but not limited to, about 80 degrees. Once a delay time elapses, the angle value sensed by the second sensor 230 is greater than the third threshold (eg, about 80 degrees). , indicating that the user really wants to continue to use the sounding device 200. At this time, the second sensor 230 is not required to be turned on or off by the second sensor 230. Therefore, the second sensor 230 is turned off by the above control to save energy. The purpose.

In addition, the sounding device 400 includes a wireless receiving module 410, an amplifier 420, and a broadcaster 430. In the connection relationship, the wireless receiving module 410 is coupled to the amplifier 420, and the amplifier 420 is coupled to the sounder 430. The above-mentioned radio receiver 210 is configured to receive and convert the sound into an audio signal. When the sound transmitting device 200 is turned on, the audio signal is transmitted through the wireless transmission module 250. The wireless receiving module 410 of the broadcast device 400 receives and transmits the audio signal to the amplifier 420, and the audio signal is received and processed by the amplifier 420, and then the sound is played by the broadcaster 430 according to the processed audio signal.

Referring to FIG. 4, in an embodiment, the sounding device 400 further includes a receiving slot 460. Different from the detector 280 illustrated in FIG. 2, the detector 280 of the sound transmitting device 200 shown in FIG. 4 detects whether the sound transmitting device 200 is coupled to the receiving slot 460 of the sounding device 400. The sound device 200 is coupled to the receiving slot 460. At this time, the detector 280 of the sound transmitting device 200 transmits a closing signal to the power source 270, and the power source 270 is turned off according to the closing signal, thereby turning off the sound transmitting device 200.

In another embodiment, the sounding device 400 further includes a processor 440 and a power source 450. In the connection relationship, the wireless receiving module 410, the amplifier 420 and the broadcaster 430 are respectively coupled to the processor 440 and the power source 450, and the processor 440 controls the operations of the wireless receiving module 410, the amplifier 420 and the broadcaster 430. . In addition, the processor 440 is also coupled to the power source 450, and the power source 450 provides power to the wireless receiving module 410, the amplifier 420, the broadcaster 430, and the processor 440. The receiving slot 460 is coupled to the power source 450. In the same manner as the detector 280 of the sound transmitting device 200, a corresponding detecting component (not shown) may be disposed in the receiving slot 460 for transmitting when the sound transmitting device 200 is coupled to the receiving slot 460. A signal is turned off to the power source 450, causing the power source 450 to turn off to provide power, thereby turning off the sounding device 400.

Further, the power source 450 is used to provide power to the various components of the sounding device 400.

FIG. 5 is a flow chart showing a method 500 of controlling an electronic device according to still another embodiment of the present invention. The above control method 500 can be used to control various electronic devices having at least two inductors, and the power consumption of the inductors is different. For convenience of explanation, the first inductor and the second inductor are exemplarily illustrated herein, and the power consumption of the first inductor is lower than the power consumption of the second inductor.

The above control method 500 of the electronic device includes the following processes:

Sensing the first parameter value by the first sensor;

Comparing the first parameter value with the first threshold to determine whether to turn on the second inductor;

When the second sensor is turned on, the second parameter is sensed by the second sensor;

The second parameter value and the second threshold are compared to determine whether to turn on the electronic device.

In order to make the above process understandable, please refer to Figure 4 and Figure 5 together. It should be noted that the electronic device may be, but not limited to, various electronic devices including sensors and radios, such as mobile phones, tablet computers, etc., and is not limited to the sound transmitting device 200 shown in FIG. In step 512, the first sensor 220 is turned on to sense the first parameter value by the first sensor 220. In step 520, the first parameter value is compared with the first threshold to determine whether to turn on the second sensor. For example, the processor 260 determines whether the first parameter value is greater than the first threshold, and determines the first When the parameter value is greater than the first threshold, step 522 is performed, and the second inductor 230 is turned on by the processor 260. In step 522, the second sensor 230 has been turned on, so that the second parameter value is sensed by the second sensor 230. In step 530, the second parameter value and the second threshold are compared to determine whether to turn on the electronic device. For example, the processor 260 determines whether the second parameter value is greater than the second threshold, and determines the second parameter value. When the value is greater than the second threshold, step 536 is executed, and the electronic device is turned on by the processor 260 to cause the electronic device to be in an on state.

In step 512, for example, the first sensor 220 can be, but is not limited to, an acceleration sensor for sensing an acceleration value of the electronic device, and the first threshold can be, but not limited to, an acceleration threshold. In step 520, the second inductor 230 can be turned on when the acceleration value sensed by the processor 260 at the first sensor 220 is greater than the acceleration threshold. In the step 522, for example, the second sensor 230 can be, but is not limited to, a gyroscope for sensing the angle value of the electronic device. The second threshold value can be, but is not limited to, an angle threshold. For example, the second sensor 230 can be a gyroscope, a timer or other type of sensor. Accordingly, the second parameter value induced by the second sensor 230 can have multiple types of parameter information, such as an angle value, an angular change amount, Time value or other type parameter information. In step 536, when the angle value sensed by the processor 260 on the second sensor 230 is greater than the angle threshold, the electronic device is controlled to be turned on to cause the electronic device to be in an on state.

According to the control method 500 of the electronic device, when the user picks up the electronic device from the flat on the desktop, the first sensor 220 of the electronic device senses an acceleration value once the value exceeds the preset acceleration valve. The value is then turned on by the processor 260 to the second sensor 230. Then, if the user wants to use the electronic device, the user will pick up the electronic device and have an angle with the ground. Therefore, after the user picks up the electronic device and turns on the second sensor 230, the electronic device The second sensor 230 senses an angle between the electronic device and the ground. Once the value exceeds the preset angle threshold, the processor 260 turns on the electronic device for the user to operate.

In this way, the user does not need to manually turn on or off the electronic device, but the case intelligently controls the electronic device according to the operating situation, which is convenient for the user to control. Moreover, since the power consumption of the first sensor 220 is smaller than that of the second sensor 230, the first sensor 220 with low power consumption can make a preliminary judgment on the operating situation, and according to the judgment result, it is determined whether to turn on the sensing. The sensitive but relatively energy-consuming second sensor 230 opens the electronic device with precise sensing of the operating situation for energy saving purposes. Further, if the low-power first sensor 220 determines that the operating situation does not match after the initial judgment, the second sensor 230 with high power consumption is not turned on, thereby achieving the purpose of energy saving, thereby extending the electronic device. usage time.

In an embodiment, the control method 500 further includes a step 510 of determining whether the pin of the electronic device is connected to the charging device, and determining whether to turn on the first sensor. Referring to FIG. 4 and FIG. 5, for example, if the electronic device (eg, the sound transmitting device 200) is not connected to the charging device (eg, the receiving slot 460 of the sounding device 400), step 512 is performed, by electronic The detector 280 of the device transmits a detection signal to the processor 260 to turn on the first sensor 220 by the processor 260. If the electronic device is connected to the charging device, step 514 is executed, and the electronic device detector 280 transmits a shutdown signal to the power source 270 to turn off the power source 270 to turn off the electronic device.

In another embodiment, if it is determined in step 520 that the first parameter value is not greater than the first threshold, step 524 is performed to determine whether the pin of the electronic device is connected to the charging device. Referring to FIG. 4 and FIG. 5, for example, if the electronic device (eg, the sound transmitting device 200) is not connected to the charging device (eg, the receiving slot 460 of the sounding device 400), step 520 is performed. The processor 260 determines if the first parameter value is greater than the first threshold. If the electronic device is connected to the charging device, step 514 is executed, and the electronic device detector 280 transmits a shutdown signal to the power source 270 to turn off the power source 270 to turn off the electronic device.

In still another embodiment, if it is determined in step 530 that the second parameter value is not greater than the second threshold, step 532 is performed, and the processor 260 determines whether the amount of change of the second parameter value in a delay time is greater than Four thresholds. For example, if the user picks up the electronic device (eg, the sound transmitting device 200) from the flat on the table, the second sensor 230 is turned on. At this time, if the angle between the electronic device and the ground is not greater than the angle threshold, there are many reasons for this. For example, it is not appropriate to turn off the electronic device. Accordingly, if the angle value sensed by the second sensor 230 is not greater than the angle threshold, step 532 is executed, and the processor 260 determines whether the amount of change of the angle value within a delay time is greater than the angle variation threshold.

If the angle value change amount is greater than the angle change amount threshold, it means that the user keeps holding the electronic device and the hand is shaken. At this time, the user is more likely to continue using the electronic device. Therefore, step 530 needs to be performed again to It is judged whether the angle value sensed by the second inductor 230 is greater than the angle threshold, and is controlled according to the judgment result. On the other hand, if the angle value change amount is not greater than the angle fluctuation amount threshold, it means that the user puts the electronic device back on the table. At this time, step 534 is performed. In step 534, if the electronic device has not been turned on, the electronic device is maintained in the original closed state, such as the microphone 210, the screen 240, the wireless transmission module 250, and the like of the sound transmitting device 200 shown in FIG. The original closed state is maintained to cause the sound transmitting device 200 to be in a closed state. On the other hand, if the electronic device has been turned on, the electronic device is turned off, such as turning off the sound collector 210 and the screen of the sound transmitting device 200 shown in FIG. 240, a wireless transmission module 250, etc., to turn off the sound transmitting device 200, so that the sound transmitting device 200 is in a closed state. Subsequently, the second inductor 230 is turned off in step 542.

In yet another embodiment, control method 500 further includes step 540 to determine if the second parameter value is greater than a third threshold. Referring to FIG. 4 and FIG. 5 together, when the electronic device (eg, the sound transmitting device 200) is turned on, when the second parameter value sensed by the second sensor 230 is greater than the third threshold, the execution is performed. Step 542 is to close the second sensor 230. For example, if the user continues to hold the sounding device 200 for speech, singing, etc., indicating that the user wants to continue using the sound transmitting device 200, the user will hold the transmission in a manner that is nearly perpendicular to the ground. The acoustic device 200, therefore, sets the third threshold to, but not limited to, about 80 degrees. Once a delay time elapses, the angle value sensed by the second sensor 230 is greater than the third threshold (eg, about 80 degrees). , indicating that the user really wants to continue to use the sounding device 200. At this time, the second sensor 230 is not required to be turned on or off by the second sensor 230. Therefore, the second sensor 230 is turned off by the above control to save energy. The purpose.

In other embodiments, the second sensor 230 can be, but is not limited to, a composite sensor that can simultaneously sense different types of parameters. Therefore, the second parameter value can include, but is not limited to, maintaining the turn-on time of the electronic device. The three thresholds can be, but are not limited to, time thresholds. The processor 260 controls to turn off the second sensor 230 when the hold-on time (eg, the electronic device is continuously turned on for 5 minutes) is greater than the time threshold (eg, the time threshold is 3 minutes). In this way, when the user continues to operate with the electronic device, indicating that the user wants to continue to use the electronic device, the electronic device is not required to be turned on or off through the second sensor 230. Therefore, the control is turned off by the above control. The second sensor 230 is used for energy saving purposes. Moreover, when the second parameter value sensed by the second sensor 230 is not greater than the third threshold, step 530 is performed to determine whether the second parameter value is greater than the second threshold.

In another embodiment, please refer to FIG. 4 and FIG. 5 together, the electronic device (eg, the sound transmitting device 200) further includes a third sensor (not shown) to sense the third of the electronic device. Parameter value. The third sensor can be turned on when the electronic device is turned on. In this embodiment, step 540 may be: “determining whether the third parameter value is greater than a third threshold.” The third sensor may be, but not limited to, a timer, and correspondingly, the third sensor senses The three parameter value may be, but is not limited to, a maintenance on time of the electronic device. Further, the third threshold may be, but is not limited to, a time threshold. When the maintenance on time (eg, the sound device 200 is continuously turned on for 5 minutes) is greater than the time threshold (eg, the time threshold is 3 minutes), in step 542, the second sensor 230 may be further turned off by the processor 260. With the third inductor described above. In this way, when the user continues to hold the sounding device 200 for speech, singing, etc., indicating that the user wants to continue using the sound transmitting device 200, at this time, the second sensor 230 or the third sensor is not required. In order to sense the state of the sound transmitting device 200, the second sensor 230 and the third sensor are turned off by the above operation to save energy.
