Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating an implementation of a control method according to an embodiment of the present invention, where the embodiment is applied to an electronic device such as a mobile phone, a pad, an all-in-one machine, or a desktop computer having a speaker, and heat dissipation of the speaker is implemented by processing a sound signal output by the speaker. The following steps may be specifically included in fig. 1:
step 101: and detecting the temperature value of the loudspeaker when the loudspeaker outputs the sound signal.
The temperature value of the loudspeaker can be detected by a temperature sensor.
Step 102: and judging whether the temperature value of the loudspeaker exceeds a preset temperature range, if so, executing step 103, and if not, not operating the sound signal.
The temperature range here may be set according to the temperature resistance characteristics of the speaker.
In one implementation, the maximum value in the temperature range may be set as the highest temperature at which the speaker normally operates, so that when the temperature value of the speaker is found to be greater than the highest temperature at which the speaker can normally operate, this embodiment indicates that the speaker is in an abnormal state with a high temperature, and at this time, the speaker needs to be cooled, and step 103 is executed.
In another implementation, the maximum value in the temperature range may be set to be an intermediate value lower than a preset maximum temperature threshold, so that when the temperature value is found to be greater than the intermediate value, this embodiment indicates that if the speaker is not cooled, the temperature value of the speaker reaches the maximum temperature after a certain time, in this embodiment, the speaker needs to be pre-cooled, so as to avoid that the temperature value of the speaker reaches the maximum temperature, that is, step 103 is executed.
Step 103: the first signal is added to the sound signal.
After the first signal is added to the sound signal, when the sound signal is output through the loudspeaker, the amplitude of the vibration diaphragm in the loudspeaker can be increased due to the addition of the first signal, and therefore air flow in the loudspeaker is promoted to dissipate heat.
In a specific implementation, the first signal may be a signal with a frequency less than or equal to a preset first frequency threshold, such as a low frequency signal: the signal with the frequency of 50HZ, because the characteristic that the low frequency signal can cause the vibrations of its output device, after adding the low frequency signal in the sound signal, the vibrating diaphragm in the speaker of output sound signal can accelerate the vibration because of this low frequency signal, and then accelerates the flow of air in the speaker, realizes the heat dissipation to the speaker.
According to the control method provided by the embodiment of the invention, when the temperature value of the loudspeaker outputting the sound signal is detected to be beyond the preset temperature range, the first signal capable of increasing the amplitude of the vibrating diaphragm in the loudspeaker is added into the sound signal, so that the air flow in the loudspeaker can be promoted, the flowing air can realize the heat dissipation of the loudspeaker, the temperature of the loudspeaker is reduced, the service life of the loudspeaker is prolonged, and the use experience of a user is obviously improved.
In a specific implementation, when the first signal is added to the sound signal, this embodiment may be implemented by step 203 in fig. 2:
step 203: the first signal is added at a point in the sound signal corresponding to the second signal.
In this embodiment, the low-frequency signal is added at the time point of the high-frequency signal in the sound signal, that is, at the time point of the high-frequency signal without the low-frequency signal, so that, in the output process of the high-frequency signal through the speaker, the vibration diaphragm in the speaker generates vibration with a certain amplitude, thereby accelerating the flow of air in the speaker and realizing the heat dissipation of the speaker.
It should be noted that step 201 and step 202 in fig. 2 are the same as step 101 and step 102 in fig. 1, and are not described in detail here.
Fig. 3 is another flowchart of the embodiment of the present invention, in this embodiment, if it is determined that the temperature value of the speaker is out of the temperature range, the heat dissipation of the speaker may be accelerated by the following steps:
step 304: it is determined whether the input power of the sound signal is outside the power range of the speaker and if the input power is outside the power range, step 305 is performed.
The power range can be set according to the rated power and the maximum power of the speaker.
In one implementation, the maximum value in the power range may be set as the maximum output power of the speaker, and thus, when it is found that the temperature value of the speaker exceeds the temperature range and the input power of the sound signal is greater than the maximum output power of the speaker, this embodiment indicates that the speaker is in the high-temperature abnormal state and the input power of the sound signal is at least a part of the reason for the high-temperature operation of the speaker, and at this time, in addition to performing step 303 to dissipate heat of the speaker, the heat may be dissipated by performing step 305.
Step 305: the output parameters of the loudspeaker are adjusted so that the output power of the loudspeaker is within a power range when the sound signal is output through the loudspeaker.
Here, the adjusting of the output parameter of the speaker may specifically be: the power amplifier parameters of the loudspeaker are reduced, for example, the amplification factor of the power amplifier is reduced or the system gain is reduced, so that the output function of the loudspeaker can be in a power range when the sound signal is output through the loudspeaker, and the loudspeaker is not contributed to more heat generation.
Fig. 4 is a schematic structural diagram of an electronic device according to an embodiment of the present invention, where the electronic device may include the following structures:
the speaker 401, the controller 402, the memory 403, the temperature sensor 404, the bus 405, and the like may be connected to the bus 405 through interfaces, and the speaker 401, the controller 402, and the memory 403 may transmit data through the bus 405.
The memory 403 is used for storing audio signals, various applications, data generated during the operation of the applications, and the like.
The speaker 401 is used to output an acoustic signal.
The controller 402 firstly utilizes the temperature sensor 404 to acquire a temperature value of the loudspeaker when the loudspeaker 401 outputs sound, and then judges whether the temperature value exceeds a preset temperature range, if the temperature value exceeds the temperature range, a first signal is added into the sound signal, so that the amplitude of a vibration diaphragm in the loudspeaker 401 is increased by the first signal when the sound signal is output through the loudspeaker 401, and the air flow in the loudspeaker 401 is promoted to dissipate heat.
It should be noted that the controller 402 can utilize the comparator to determine whether the temperature value exceeds the preset temperature range.
In addition, in order to accelerate the heat dissipation of the speaker, in this embodiment, an opening 407 may be disposed on the housing 406 of the electronic device, as shown in fig. 5, the position of the opening 407 may be opposite to the position of the speaker 401, so that the heat generated by the speaker 401 may be exhausted out of the housing 406 through the opening 407, and after the vibration of the speaker is accelerated due to the vibration diaphragm added with the first signal, the heat carried by the accelerated air flow can be exhausted out of the housing 406 through the opening 407 more quickly.
The opening 407 may be plural and is provided in a region of the housing 406 opposite to the position of the speaker 401, such as a region S in fig. 5.
In a specific implementation, the controller 402 may add a first signal to a time point corresponding to a second signal in the sound signal, where a frequency of the first signal is less than a preset first frequency threshold, a frequency of the second signal is greater than or equal to a preset second frequency threshold, and the second frequency threshold is greater than the first frequency threshold. That is, the controller 402 adds a low frequency signal to a high frequency signal of the sound signal, and further causes the speaker 401 to vibrate the diaphragm during an output period of the high frequency signal, so as to accelerate air flow and achieve heat dissipation.
In other implementations, the controller 402 is further configured to determine whether the input power of the sound signal exceeds a power range of the speaker 401, such as a maximum power range, after finding that the temperature value exceeds the temperature range, and adjust the output parameter of the speaker 401 if the input power of the sound signal exceeds the power range, so that the output power of the speaker 401 is within the power range when the sound signal is output through the speaker 401.
In the adjustment of the output parameters of the speaker 401, the controller 402 may reduce the power amplifier parameters of the speaker 401, such as the amplification factor of the power amplifier or the system gain, so that the output function of the speaker 401 may be in the power range when the sound signal is output through the speaker 401, and may not contribute to the generation of more heat to the speaker 401.
