According to an embodiment, the processor 340 may control the rotation speed of the cooling fan 320 based on the output power of the audio data and the frequency information of the audio data. According to an embodiment, the output power of the audio data may correspond to the amplification strength of the audio data. For example, the output power of the audio data may correspond to a volume level when the audio data is output to the outside. For example, audio data having a large value of output power may correspond to a sound of a large volume, and audio data having an output power of a small value may correspond to a sound of a low volume. According to an embodiment, the output power of the audio data may be determined by a user of the electronic device and/or may be determined by various operations of the processor 340 . According to an embodiment, the frequency information of the audio data may indicate whether the audio data corresponds to (or includes) a specified frequency band. According to an embodiment, the frequency information of the audio data may be information generated based on the frequency of the audio data. For example, the audio data frequency information may be information generated by extracting and processing at least a portion of the frequency of the audio data. For example, audio data frequency information is generated based on a specified frequency band of audio data filtered through a digital filter (eg, fan noise audible band filter) of an audio conversion circuit (eg, audio conversion circuit 531 in FIG. 5) may be information.

According to an embodiment, while the user of the electronic device 300 listens to the sound corresponding to the audio data, the noise generated during the operation of the cooling fan 320 may be covered by the sound corresponding to the audio data. For example, the user of the electronic device 300 audibly hears the noise of the cooling fan 320 because the user of the electronic device 300 listens to a sound corresponding to the audio data being reproduced even when noise is generated by the operation of the cooling fan 320 . It may not be recognized or may feel less discomfort due to the noise of the cooling fan 320 . By using such a user's auditory characteristics, the processor 340 may control the cooling fan 320 to rotate at a higher rotation speed as the output power (eg, volume) of the audio data being reproduced increases. The greater the output power of the audio data being reproduced, the greater the sound (eg, a sound corresponding to the audio data) heard by the user. Noise may not be perceived.

According to an embodiment, the processor 340 may determine the rotation speed of the cooling fan 320 based on output power of audio data reproduced by the electronic device 300 and frequency information of the audio data. A user (eg, a human) of the electronic device 300 may easily recognize a sound of a relatively high frequency band rather than a sound of a relatively low frequency band. For example, the user of the electronic device 300 may audibly recognize a sound of a high frequency band corresponding to 1 kHz to 2 kHz rather than a sound of a low frequency band of 1 kHz or less. According to an embodiment, the user of the electronic device 300 may recognize a sound corresponding to a specified frequency band more aurally and more sensitively than a sound of another frequency band, even if the sound has the same output power. In an embodiment, the user of the electronic device 300 may change the volume (eg, volume) of a sound corresponding to a specified frequency band to a frequency other than the specified frequency band, even if the sound has the same output power. It can be recognized as being larger than the volume of the sound corresponding to the band. For example, the designated frequency band may correspond to a frequency band of 1 kHz to 2 kHz. For example, the frequency band other than the designated frequency band may correspond to the remaining frequency bands except for the designated frequency band among the audible frequency bands (eg, 20 Hz to 20 kHz). According to an embodiment, the processor 340 may control the rotation speed of the cooling fan 320 by using the output power of audio data and frequency information of the audio data together using the aforementioned user's auditory characteristics. . Hereinafter, the designated frequency band may correspond to a frequency band (eg, 1 kHz to 2 kHz) in which a user of the electronic device 300 can easily (or sensitively) recognize a sound.

According to an embodiment, the processor 340 may determine the rotation speed of the cooling fan 320 using output power of the reproduced audio data and frequency information of the reproduced audio data.

According to an embodiment, the output power of the audio data is equal to or less than a specified value (eg, the first control signal includes the first state information), and the frequency information of the audio data corresponds to a frequency other than the specified frequency band ( Example: It may indicate that the second control signal includes the third state information). For example, the frequency information of the audio data may indicate that an audio signal corresponding to a frequency other than a specified frequency band is included in the reproduced audio data. According to an embodiment, the processor 340 may determine the rotation speed of the cooling fan 320 as the first speed. For example, in the first speed, when the output power of the audio data is less than or equal to a specified value and the audio data corresponds to a frequency other than the specified frequency band, the user reduces the noise generated by the rotation of the cooling fan 320 . It may correspond to the rotational speed of the cooling fan 320 of the maximum size, which cannot be recognized aurally. Alternatively, in the first speed, when the output power of the audio data is equal to or less than a specified value and the audio data corresponds to a frequency other than the specified frequency band, the user can hear noise generated by the rotation of the cooling fan 320 . It can correspond to the rotation speed of the cooling fan 320 of the maximum size, which can be perceived as but not obtrusive. For example, the cooling fan 320 rotating at the first speed may generate noise of a magnitude corresponding to 50 dB (or 40 dB to 50 dB) for example. Alternatively, the first speed may be defined as hearing caused by noise generated by the rotation of the cooling fan 320 by the user in a state where the output power of the audio data is equal to or less than a specified value and the audio data corresponds to a frequency other than the specified frequency band. It can correspond to the rotation speed of the cooling fan 320 of the maximum size, which does not feel any inconvenience.

According to an embodiment, the output power of the audio data is equal to or less than the specified value (eg, the first control signal includes the first state information), and the frequency information of the audio data corresponds to a frequency band in which the audio data is specified (eg: may indicate that the second control signal includes the fourth state information). For example, the frequency information of the audio data may indicate that an audio signal included in a specified frequency band is included in the reproduced audio data. In this case, the processor 340 may determine the rotation speed of the cooling fan 320 as a second speed exceeding the first speed. According to an exemplary embodiment, the noise generated by the cooling fan 320 rotating at the second speed may be relatively increased compared to that generated by the cooling fan 320 rotating at the first speed. According to an embodiment, the user may audibly recognize that the sound corresponding to the audio data is increased by the audio data corresponding to the specified frequency band. Since the user of the electronic device 300 cannot recognize the noise of the cooling fan 320 by the sound of the audio data recognized as having an increased volume even if the noise level of the cooling fan 320 increases, the user of the electronic device 300 cannot recognize the noise of the cooling fan 320. ) may improve cooling efficiency by controlling the cooling fan 320 to rotate at the second speed. In various embodiments, the processor 340 may adaptively control the speed of the cooling fan 320 . For example, the processor 340, the cooling fan 320 rotates at the first speed, the frequency information is changed (eg, the frequency information is changed to indicate the fourth state information from the third state information) Based on the , the rotation speed of the cooling fan 320 may be changed to the second speed. An example of the rotation speed of the cooling fan 320 controlled by the processor 340 will be described with reference to FIGS. 4A and 4B to be described later.

In the manner described above, the processor 340 may determine the rotation speed of the cooling fan 320 based on the output power of the audio data and the frequency information of the audio data. According to an embodiment, the processor 340 determines the rotation speed of the cooling fan 320 that generates a noise that the user cannot audibly recognize based on the output power of the audio data and the frequency information of the audio data. can

In various embodiments, the processor 340, based on the frequency information of the audio data to be reproduced, is configured to correspond to a specified frequency band in which the audio data is easily recognized aurally by the user (eg, recognized as a loud sound). can recognize that According to an embodiment, the processor 340 may increase the rotation speed of the cooling fan 320 by a specified amount while frequency information of the reproduced audio data corresponds to a specified frequency band. According to an embodiment, the processor 340 prevents the user from easily feeling the noise caused by the increased rotation speed of the cooling fan 320 due to the sound corresponding to the audio data corresponding to the specified frequency band, and at the same time, the increased The temperature of the electronic device 300 may be reduced within a short time by using the cooling fan 320 rotating at a rotation speed. Hereinafter, operations described as being performed by the electronic device with reference to drawings to be described later may be referred to as being performed by the processor 340 .

According to an embodiment, the second control signal may indicate whether audio data corresponds to a specified frequency band. In an embodiment, when the audio data corresponds to a frequency band other than the designated frequency band, the second control signal may include the third state information B1. For example, the third state information B1 may indicate that reproduced (or reproduced) audio data includes an audio signal having a frequency out of a specified frequency band. In an embodiment, when the audio data corresponds to a specified frequency band, the second control signal may include the fourth state information B2. For example, the fourth state information B2 may indicate that reproduced audio data includes an audio signal having a frequency within a specified frequency band.

For example, the second speed R2 may correspond to a value exceeding the first speed R1 . Referring to FIG. 4A , the first control signal does not change during the initial time t0 to the second time t2, but the second control signal transmits the fourth state information B2 based on the first time t1. may be modified to include For example, audio data reproduced from the first time (t1) to the second time (t2) is in a specified frequency band (eg, a frequency band that can be recognized by a user relatively loudly (or sensitively)). can respond. During the first time (t1) to the second time (t2), the user does not audibly recognize the noise caused by the rotation of the cooling fan because the sound of the reproduced audio data is obscured, so the processor adjusts the rotation speed of the cooling fan to the first It can increase from the speed R1 to the second speed R2.

For example, the third speed R3 may correspond to a different value from the first speed R1 and the second speed R2 . In various examples, the third rate R3 may correspond to a value greater than the first rate R1 and less than or equal to the second rate R2 . Referring to FIG. 4A , although the output power of the audio data reproduced based on the second time t2 is increased, the reproduced audio data may be changed to correspond to a frequency band other than a specified frequency band.

Referring to FIG. 4A , there is no change in the output power of the audio data reproduced based on the third time t3 , but the reproduced audio data may be changed to correspond to a specified frequency band. During the third time (t3) to the fourth time (t4), the user does not audibly recognize the noise caused by the rotation of the cooling fan because it is obscured by the sound of the reproduced audio data, so the processor adjusts the rotation speed of the cooling fan to the maximum speed. It can be determined as the fourth speed R4. In various embodiments, the first control signal and the second control signal may be configured with a logic value including 0 and 1 (eg, high or low).

According to an embodiment, the first section in which the temperature of the electronic device is equal to or less than the threshold value may correspond to a section in which the electronic device can achieve expected performance. In the first section, the processor may cause the cooling fan to rotate at any one of A speed (RA), B speed (RB), and C speed (RC). For example, the A speed RA, the B speed RB, and the C speed RC may correspond to values smaller than the first to fourth speeds R1, R2, R3, and R4. In one embodiment, the processor may increase the rotation speed of the cooling fan in the first section linearly or stepwise.

In the second section, the processor may determine the rotation speed of the cooling fan as the first to fourth speeds R1, R2, R3, and R4 based on the above-described first and second control signals. According to an embodiment, the processor may control the rotation speed of the cooling fan to the first to fourth speeds R1, R2, R3, and R4 in the second section to reduce the temperature of the electronic device within a short time. For example, the fourth speed R4 may correspond to the maximum allowable speed of the cooling fan.

4B exemplarily illustrates a case where the threshold value corresponds to 55 degrees Celsius. For example, in a first section in which the temperature of the electronic device corresponds to 0 degrees Celsius to 55 degrees Celsius, the processor may determine whether the cooling fan operates at any one of A speed (RA), B speed (RB), and C speed (RC). It can be rotated at one speed. For example, in the first section, when the temperature of the electronic device exceeds 42 degrees Celsius, the processor may control the rotation speed of the cooling fan to the A speed RA. For example, in the first section, when the temperature of the electronic device exceeds 47 degrees Celsius, the processor may control the rotation speed of the cooling fan to the B speed RB. For example, in the first section, when the temperature of the electronic device exceeds 49 degrees Celsius, the processor may control the rotation speed of the cooling fan to the C speed (RC).

According to an embodiment, in the second section in which the temperature of the electronic device exceeds 55 degrees Celsius, the processor operates the cooling fan at the first to fourth speeds (R1) using the first and second control signals described above. , R2, R3, R4) can be rotated. The processor may control the cooling fan to rotate at a higher speed in the second section than in the first section, thereby effectively lowering the temperature of the electronic device.
