For example, the motor 303 may be operated to provide a call reception notification to the user by vibration. For example, the motor 303 may be operated to provide a message window notification to the user by vibration. For example, the motor 303 may be operated to provide an alarm notification to the user by vibration. For example, the alarm may be a wake-up call. According to an embodiment, the vibration of the motor 303 may be detected by the user using the sense of touch. The vibration sound signal generated by the motor 303 may have a small intensity. Even if the motor 303 operates, the user may not be able to detect the vibration using the sense of hearing. Therefore, when the electronic device 301 is not in contact with the user, the user may not be able to detect the vibration of the motor 303.

[0060] In order to reduce the situation that the user does not recognize the vibration of the motor 303, the electronic device 301 can output a vibration sound signal. The electronic device 301 can generate a vibration sound signal corresponding to the vibration of the motor 303 so as to provide a notification based on the user's hearing. The electronic device 310 can output the generated vibration sound signal through the speaker 309. According to an embodiment, the vibration sound signal can be generated based on the vibration frequency of the motor 303 so that the user feels that the vibration sound signal is similar to the vibration of the motor 303. In addition, according to an embodiment, the vibration sound signal can be generated based on the intensity of the ambient sound received by the microphone 307. Ambient sound can mean a sound other than the expected vibration sound signal, for example, a noise signal.

[0061] According to an embodiment, the processor 305 may control components of the electronic device 301. The processor 305 may identify a control signal for operating the motor 303. The processor 305 may identify a control signal for generating a vibration sound signal. The processor 305 may generate a vibration sound signal through the audio module 170. The vibration sound signal may be generated based on the vibration frequency of the motor 303.

[0062] According to an embodiment, the processor 305 may generate a vibration sound signal based on the first frequency signal and the second frequency signal. The processor 305 may generate a vibration sound signal by superimposing a high-order harmonic frequency on the vibration frequency of the motor 303 so that it can be recognized by the user's ears. The frequency of the multiple of the vibration frequency of the motor 303 may be referred to as a harmonic frequency. According to an embodiment, the vibration sound signal may be generated by synthesizing the first frequency signal and the second frequency signal. The frequency of the first frequency signal (hereinafter, the first frequency) may correspond to the vibration frequency of the motor 303. The frequency of the second frequency signal (hereinafter, the second frequency) may be a multiple (for example, two times or three times) of the vibration frequency of the motor 303. Compared with the sound generated by synthesizing the first frequency signal and the third frequency signal, the sound generated by synthesizing the first frequency signal and the second frequency signal may have a similar tone to the first frequency. The frequency of the third frequency signal may not be a multiple of the first frequency. The third frequency signal having a frequency other than a multiple of the first frequency has a different tone from the vibration sound of the motor, and therefore may not be felt by the user as the vibration sound of the motor. The component corresponding to the vibration frequency of the motor may be generated by the harmonic frequency. Therefore, the user can recognize the harmonic frequency having a frequency that is a multiple of the vibration sound frequency of the motor as the motor sound.

[0063] It is described that the second frequency signal generating the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. For example, the second frequency may not be a harmonic frequency of the first frequency.

[0064] It is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0065] According to an embodiment, the sound pressure of the first frequency signal may be the first sound pressure. The sound pressure of the second frequency signal may be the second sound pressure. The processor 305 may generate a vibration sound signal by synthesizing the first frequency signal and the second frequency signal. For example, the second frequency may be a multiple of the first frequency. This is because the vibration sound signal generated based on the second frequency signal having a frequency of a multiple of the first frequency has a similar tone to the first frequency signal. The third frequency signal having a frequency other than a multiple of the first frequency has a different tone from the vibration sound of the motor 303, and therefore may not be felt by the user as the vibration sound of the motor 303. The user may identify the harmonic frequency of the frequency of the vibration sound of the motor 303 as the vibration sound of the motor 303. This is because a component corresponding to the vibration frequency of the motor 303 can be generated by the harmonic frequency.

[0066] According to an embodiment, when the second sound pressure is larger, the user can better hear the vibration sound signal even with the same intensity. For example, the frequency of the vibration of the motor 303 can be about 150 Hz. Within the frequency range of the vibration sound signal (for example, from about 150 Hz to about 600 Hz), when the second frequency of the second frequency signal becomes higher, the user can better hear the second frequency signal even with the same sound intensity. Therefore, compared with the vibration sound signal generated based on the second frequency signal with a large second sound pressure, the user can better hear the vibration sound signal generated based on the second frequency signal with a small second sound pressure. Figure 5 The reason why users can hear sounds better as the frequency of sounds becomes higher is described in.

[0067] According to an embodiment, when the first sound pressure as the sound pressure of the first frequency signal is larger, the user can feel that the heterogeneity between the vibration of the actual motor 303 and the vibration sound signal is lower. This is because, when the first sound pressure is larger, the difference between the frequency of the vibration transmitted by the sense of touch and the frequency of the vibration sound signal transmitted by the sense of hearing can be smaller. For example, in the case where the motor 303 transmitted by the sense of touch vibrates at about 150Hz and the frequency of the vibration sound signal transmitted by the sense of hearing is about 150Hz, the heterogeneity felt by the user due to the mismatch between the sense of touch and the sense of hearing will be lower than the case where the frequency of the vibration sound signal transmitted by the sense of hearing is about 300Hz. However, even if the user feels a sense of heterogeneity at a vibration sound signal of about 300Hz, since the vibration sound signal of about 300Hz is also a harmonic frequency, it can be identified as the vibration sound of the motor vibrating at a frequency different from that of the motor 303 of the electronic device 101.

[0068] According to an embodiment, the processor 305 may determine a first sound pressure of a first frequency signal having a frequency corresponding to the vibration frequency of the motor and a second sound pressure of a second frequency signal having a frequency different from the vibration frequency of the motor (e.g., a multiple of the vibration frequency of the motor) based on the intensity of the sound (hereinafter, the ambient sound) input through the microphone 307. For example, in the case where the intensity of the sound input through the microphone 307 is greater than or equal to the threshold, the processor 305 may determine the first sound pressure and the second sound pressure so that the first sound pressure is lower than the second sound pressure. The second sound pressure is set to be higher than the first sound pressure in order to improve the transmissibility of the vibration sound signal generated based on the first frequency signal and the second frequency signal. For example, in the case where the intensity of the sound input through the microphone 307 is lower than the threshold, the processor 305 may determine the first sound pressure and the second sound pressure so that the first sound pressure is greater than the second sound pressure. The first sound pressure is set to be higher than the second sound pressure in order to reduce the heterogeneity between the vibration sound signal generated based on the first frequency signal and the vibration of the motor 303.

[0069] According to an embodiment, a vibration sound signal may be generated based on a signal having a vibration frequency of the motor 303 and a signal having a frequency that is a multiple of the vibration frequency of the motor 303. In the case where the intensity of the signal having the vibration frequency of the motor 303 (e.g., a first frequency signal having a first sound pressure) is lower than the intensity of the signal having a frequency that is a multiple of the vibration frequency of the motor 303 (e.g., a second frequency signal having a second sound pressure), the vibration sound signal may be referred to as a first vibration sound signal. In the case where the intensity of the signal having the vibration frequency of the motor 303 is greater than the intensity of the signal having a frequency that is a multiple of the vibration frequency of the motor 303, the vibration sound signal may be referred to as a second vibration sound signal.

[0070] According to an embodiment, the processor 305 may generate a vibration sound signal through a filter. For example, the processor 305 may set the pass frequency of the high-pass filter to a first pass frequency so as to generate a first vibration sound signal. The processor 305 may generate the first vibration sound signal based on the audio signal passing through the high-pass filter. The first vibration sound signal may have a higher transmissibility than the second vibration sound signal. For example, the processor 305 may set the pass frequency of the high-pass filter to a second pass frequency so as to generate the second vibration sound signal. The second pass frequency may be lower than the first pass frequency. The processor 305 may generate the second vibration sound signal based on the audio signal passing through the high-pass filter. The second vibration sound signal may have a lower sense of heterogeneity than the first vibration sound signal.

[0071] According to an embodiment, the processor 305 may generate a vibration sound signal through the speaker 309. According to an embodiment, the processor 305 may generate a first vibration sound signal and / or a second vibration sound signal based on the intensity of the ambient sound identified by the microphone 307. For example, in a case where the intensity of the sound input through the microphone 307 is greater than or equal to a threshold value, the first sound pressure of the first frequency signal may be less than the second sound pressure of the second frequency signal, so as to improve the transmissibility of the vibration sound signal, reduce current consumption, and reduce the heating of the speaker. For example, in a case where the intensity of the sound input through the microphone 307 is lower than a threshold value, the first sound pressure of the first frequency signal may be greater than the second sound pressure of the second frequency signal, so as to reduce the heterogeneity between the vibration of the motor 303 and the vibration sound signal.

[0072] According to an embodiment, the processor 305 may change the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) based on whether the phone application is in use. For example, the processor 305 may identify whether the electronic device 301 is running (or operating) the phone application. The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a first intensity based on identifying a control signal for operating the motor 303 received when the phone application is running (or operating). The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a second intensity based on a control signal for operating the motor 303 received when the phone application is not running. The first intensity may be less than the second intensity. This is because when the phone application is running (or operating), the probability that the user is at a short distance from the electronic device 301 is high. In addition, this is because when the phone application is running (or operating), the probability that the user is in a state of contact with the electronic device 301 is high. A vibration sound signal of high intensity generated when the user is in contact with the electronic device 301 may reduce the user experience. Therefore, the processor 305 may set the intensity of the vibration sound signal (eg, the first vibration sound signal and / or the second vibration sound signal) when the phone application is operating to be lower than the intensity of the vibration sound signal when the phone application is not operating (or not running).

[0073] According to an embodiment, the processor 305 may change the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) based on whether the electronic device 301 is in use. For example, the processor 305 may identify that the electronic device 301 is in use through at least one sensor. The at least one sensor may be a proximity sensor. The at least one sensor may detect that the user's body is within a predetermined range from the electronic device 301. The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a third intensity based on identifying a control signal for operating the motor 303 received when the electronic device 301 is in use. The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a second intensity based on a control signal for operating the motor 303 received when the electronic device 301 is not in use. The third intensity may be less than the second intensity. This is because when the electronic device 301 is in use, the probability that the user is at a short distance from the electronic device 310 is high. In addition, this is because when the electronic device 301 is in use, the probability that the user is in a state of contact with the electronic device 301 is high. A vibration sound signal of high intensity generated in a state where the user is in contact with the electronic device 301 may reduce the user experience. Therefore, the processor 305 may set the intensity of the vibration sound signal (eg, the first vibration sound signal and / or the second vibration sound signal) to be lower than the intensity of the vibration sound signal when the electronic device 301 is not in use.

[0074] According to an embodiment, the processor 305 may change the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) based on whether the electronic device 301 is in use. For example, the processor 305 may identify whether the application is running. When the application is in use, the electronic device 301 may be in use. The application may be a message window application, a video sharing application, a game application, and / or a music playback application. The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a third intensity based on identifying a control signal for operating the motor 303 received when the application is running. The processor 305 may generate a first vibration sound signal and / or a second vibration sound signal with a second intensity based on a control signal for operating the motor 303 received when the application is not running. The third intensity may be less than the second intensity. This is because the probability that the user is short of the electronic device 301 when the application is running is high. In addition, this is because the probability that the user is in contact with the electronic device 301 when the application is running is high. A vibration sound signal of high intensity generated when the user is in contact with the electronic device 301 may reduce the user experience. Therefore, the processor 305 may set the intensity of the vibration sound signal (eg, the first vibration sound signal and / or the second vibration sound signal) to be lower than the intensity of the vibration sound signal when the application is not running.

[0075] According to an embodiment, the processor 305 may change the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) based on the recognition that the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) has been generated for a specified time. For example, the processor 305 may recognize that the first vibration sound signal and / or the second vibration sound signal has been generated through the speaker for a specified time. For example, the specified time may be 10 seconds. The first vibration sound signal or the second vibration sound signal may be generated with a fourth intensity. The processor 305 may generate the first vibration sound signal or the second vibration sound signal with a fifth intensity through the speaker based on the recognition that the first vibration sound signal or the second vibration sound signal has been generated through the speaker for a specified time. The fourth intensity may be less than the fifth intensity. If the vibration sound signal continues to be generated for a specified time, the probability that the user has not detected the vibration sound signal is high. For example, since the user is away from the electronic device 301, the user may not be able to check the phone notification of the electronic device 301. For example, since the user is in a deep sleep state, the user may not be able to check the alarm notification. For example, since the user is in an environment with high ambient noise, the user may not be able to check the phone notification. Therefore, when a vibration sound signal has been generated through the speaker 309 for a specified period of time, the processor 305 can set the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) to be higher than the intensity of the vibration sound signal for the specified period of time so that it can be easily detected by the user.

[0076] According to an embodiment, the audio module 170 may identify the intensity of the sound input through the microphone 307. The audio module 170 may generate a vibration sound signal through the speaker 309 according to the intensity of the sound. For example, in the case where the intensity of the sound input through the microphone 307 is greater than or equal to a threshold value, the audio module 170 may generate a first vibration sound signal based on a first frequency signal according to a first sound pressure and a second frequency signal according to a second sound pressure. The first sound pressure may be less than the second sound pressure. The second frequency of the second frequency signal may be a multiple of the first frequency of the first frequency signal. For example, in the case where the intensity of the sound is lower than a threshold value, the audio module 170 may generate a second vibration sound signal based on a first frequency signal according to a third sound pressure and a second frequency signal according to a fourth sound pressure. The third sound pressure may be greater than the fourth sound pressure. The average frequency of the first vibration sound signal may be higher than the average frequency of the second vibration sound signal.

[0077] According to an embodiment, the microphone 307 can identify the intensity of the ambient sound. The processor 305 can generate a vibration sound signal based on the intensity of the ambient sound identified by the microphone 307. According to an embodiment, the speaker 309 can generate a vibration sound signal. The vibration sound signal can correspond to the vibration of the motor 303. The processor 305 can generate a vibration sound signal by synthesizing a first frequency signal and a second frequency signal. The vibration sound generated by the motor 303 can have a small intensity. Even if the motor 303 operates, the user may not be able to detect the vibration by hearing. Therefore, when the electronic device 301 is not in contact with the user, the user may not be able to detect the vibration of the motor 303. The electronic device 301 can generate a vibration sound signal corresponding to the vibration through the speaker 309 so as to provide a notification to the user by hearing.

[0078] exist Figure 3 In the embodiment, it is described that the second frequency signal used to generate the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. For example, the second frequency may not be a harmonic frequency of the first frequency.

[0079] exist Figure 3 In the embodiment, it is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0080] exist Figure 3, it is described that a vibration sound signal is generated using a high-pass filter, but the embodiments of the present disclosure are not limited thereto. According to an embodiment, at least one processor 120 may generate a vibration sound signal through a variable filter. For example, at least one processor 120 may generate a vibration sound signal through a high-pass filter, a low-pass filter, a band-pass filter, etc. According to an embodiment, at least one processor 120 may generate a vibration sound signal through a low-pass filter. For example, at least one processor 120 may generate a first vibration sound signal through a low-pass filter. The first vibration sound signal may be generated based on recognizing that the ambient sound is greater than or equal to a threshold. For example, at least one processor 120 may set the pass frequency of the low-pass filter to a first pass frequency to generate the first vibration sound signal. At least one processor 120 may generate a first vibration sound signal based on an audio signal passing through a low-pass filter. The first vibration sound signal may have a higher transmission property than the second vibration sound signal. For example, at least one processor 120 may generate a second vibration sound signal through a low-pass filter. The second vibration sound signal may be generated based on recognizing that the ambient sound is lower than a threshold. For example, at least one processor 120 may set the pass frequency of the low-pass filter to a second pass frequency to generate a second vibration sound signal. At least one processor 120 may generate a second vibration sound signal based on the audio signal passing through a low pass filter. The first pass frequency in the low pass filter may be higher than the second pass frequency in the low pass filter. The second vibration sound signal may have a lower sense of heterogeneity than the first vibration sound signal.

[0081] Figure 4 An example of an environment in which a vibration sound signal is generated according to an embodiment is shown.

[0082] refer to Figure 4 , in state 401, via a microphone (e.g., Figure 3 The intensity of the ambient sound input by the microphone 307) may be lower than a threshold.

[0083] According to an embodiment, at least one processor (e.g. Figure 1 The processor 120 may generate a signal that is consistent with the motor (eg, Figure 3 According to an embodiment, at least one processor 120 may be included in an electronic device (eg, Figure 3 The at least one processor 120 may provide a notification to the user through the vibration of the motor 303 in the electronic device 301. For example, the at least one processor 120 may provide a call reception notification to the user through the vibration of the motor 303. For example, the at least one processor 120 may provide an alarm notification to the user through the vibration of the motor 303.

[0084] According to an embodiment, the vibration of the motor 303 can be detected by the user using the sense of touch. Even if the motor 303 operates, the user may not be able to detect the vibration sound of the motor 303 using the sense of hearing. Therefore, when the electronic device 301 is not in contact with the user, the user may not be able to detect the vibration of the motor 303. The electronic device 301 can be used through a speaker (e.g., Figure 3 The speaker 309 of the motor 303 generates a vibration sound signal corresponding to the vibration so as to provide a notification to the user through hearing. In an embodiment, the vibration sound signal can be generated based on the vibration frequency of the motor 303. For example, the vibration sound signal can be generated by synthesizing a first frequency signal and a second frequency signal. The first frequency of the first frequency signal can be the vibration frequency of the motor 303. The second frequency of the second frequency signal can be an integer multiple of the vibration frequency of the motor 303. Compared with the sound generated by synthesizing the first frequency signal and the third frequency signal, the sound generated by synthesizing the first frequency signal and the second frequency signal can have a similar tone to the first frequency. The frequency of the third frequency signal may not be an integer multiple of the first frequency.

[0085] According to an embodiment, the sound pressure of the first frequency signal may be a first sound pressure. The sound pressure of the second frequency signal may be a second sound pressure. The first frequency may be the vibration frequency of the motor 303. The second frequency may be an integer multiple of the vibration frequency of the motor 303. At least one processor 120 may generate a vibration sound signal by synthesizing the first frequency signal and the second frequency signal. According to an embodiment, at least one processor 120 may specify the first sound pressure and the second sound pressure based on the intensity of the ambient sound input through the microphone 307. For example, when the intensity of the sound input through the microphone 307 is lower than a threshold value, the first sound pressure may be greater than the second sound pressure.

[0086] According to an embodiment, when the first sound pressure is larger, the user can feel that the heterogeneity between the vibration of the actual motor 303 and the vibration sound signal is lower. This is because, when the first sound pressure is larger, the difference between the frequency of the vibration transmitted by the sense of touch and the frequency of the vibration sound signal transmitted by the sense of hearing can be smaller. For example, in the case where the motor 303 transmitted by the sense of touch vibrates at about 150Hz and the frequency of the vibration sound signal transmitted by the sense of hearing is about 1500Hz, the heterogeneity felt by the user due to the mismatch between the sense of touch and the sense of hearing will be lower than the case where the frequency of the vibration sound signal transmitted by the sense of hearing is about 300Hz. However, even if the user feels a heterogeneous feeling at a vibration sound signal of about 300Hz, since the vibration sound signal of about 300Hz is also a harmonic frequency, it can be identified as the vibration sound of a motor vibrating at a frequency different from that of the motor 303 of the electronic device 101.

[0087] In state 403, the intensity of the ambient sound input through the microphone 307 may be greater than or equal to the threshold. The vibration sound signal of the electronic device 301 may not be detected by the user through the ambient sound. The at least one processor 120 may generate a first vibration sound signal through the speaker 309.

[0088] According to an embodiment, at least one processor 120 may generate a first vibration sound signal based on a first frequency signal according to a first sound pressure and a second frequency signal according to a second sound pressure. The first sound pressure may be less than the second sound pressure. The first frequency may be a vibration frequency of the motor 303. The second frequency may be an integer multiple of the vibration frequency of the motor 303.

[0089] According to an embodiment, when the second sound pressure is larger, even with the same intensity, the user can better hear the vibration sound signal. For example, the vibration frequency of the motor 303 may be about 150 Hz. In the frequency band of the vibration sound signal (for example, between about 150 Hz and about 600 Hz), when the frequency of the vibration sound signal becomes higher, the user can better hear the vibration sound signal. Therefore, when the first vibration sound signal is generated, the second sound pressure may be greater than the first sound pressure.

[0090] exist Figure 4 In the embodiment, it is described that the second frequency signal used to generate the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. In other words, the second frequency may not be a harmonic frequency of the first frequency.

[0091] exist Figure 4 In the embodiment, it is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0092] Figure 5 Loudness contours according to frequency according to an embodiment are shown. The loudness contours may indicate the actual auditory response of a user according to the frequency of a sound.

[0093] refer to Figure 5, the graph may indicate loudness that varies according to frequency. The X-axis may be the frequency of the sound. The unit of the X-axis may be Hertz (Hz). The Y-axis may be the intensity of the sound. The unit of the Y-axis may be decibel (dB). The first line 501 indicates the actual sound intensity of the frequency of the sound that the user feels is about 100 dB. The second line 503 indicates the actual sound intensity of the frequency of the sound that the user feels is about 90 dB. The third line 505 indicates the actual sound intensity of the frequency of the sound that the user feels is about 80 dB. The fourth line 507 indicates the actual sound intensity of the frequency of the sound that the user feels is about 70 dB. The fifth line 509 indicates the actual sound intensity of the frequency of the sound that the user feels is about 60 dB. The sixth line 511 indicates the actual sound intensity of the frequency of the sound that the user feels is about 50 dB.

[0094] According to an embodiment, a vibration sound signal may be generated based on a first frequency signal and a second frequency signal. The first frequency signal may be about 150 Hz, which is a frequency of a motor (e.g., Figure 3 The second frequency of the second frequency signal may be a multiple of the first frequency of the first frequency signal. For example, the second frequency of the second frequency signal may be about 300 Hz. For example, the second frequency of the second frequency signal may be about 450 Hz. For example, the second frequency of the second frequency signal may be about 600 Hz.

[0095] According to an embodiment, in a frequency band between about 150 Hz and about 600 Hz, the frequency of the sound is higher and the user can recognize it as a sound with higher intensity. For example, a sound of about 80 dB at about 150 Hz can be felt as a smaller sound than a sound of about 80 dB at about 300 Hz. For example, a sound with a frequency of about 300 Hz and a sound with a frequency of about 150 Hz with a higher intensity can be felt by the user as sounds with the same intensity. For example, according to the frequency band, a sound with a high frequency can be better heard by the user than a sound with a low frequency even if it has a low intensity.

[0096] According to an embodiment, within the frequency range of the vibration sound signal (e.g., from about 150 Hz to about 600 Hz), when the frequency is larger, even if the sound intensity is the same, the user may feel (or perceive) that the higher frequency is louder than the lower frequency. Therefore, when generating a vibration sound signal, when the sound pressure of the second frequency signal is greater than the sound pressure of the first frequency signal, the transmissibility of the vibration sound signal may be greater than the sound pressure of the second frequency signal. For example, the transmissibility of the first vibration sound signal may be greater than the transmissibility of the second vibration sound signal. When the intensity of the ambient sound recognized by the microphone is greater than or equal to a threshold value, a first vibration sound signal may be generated. When the intensity of the ambient sound recognized by the microphone is lower than a threshold value, a second vibration sound signal may be generated.

[0097] exist Figure 5 In the embodiment, it is described that the second frequency signal used to generate the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency.

[0100] refer to Figure 6 , a vibration sound signal may be generated based on the audio signal 601. At least one processor 120 may generate a first vibration sound signal. At least one processor 120 may generate a second vibration sound signal. The high pass filter 603 may pass a signal having a frequency greater than or equal to a specified value.

[0101] According to an embodiment, at least one processor 120 may generate a first vibration sound signal through a filter. The first vibration sound signal may be generated based on recognizing that the ambient sound is greater than or equal to a threshold. For example, at least one processor 120 may set the pass frequency of the high-pass filter 603 to a first pass frequency to generate the first vibration sound signal. At least one processor 120 may generate the first vibration sound signal based on an audio signal passing through the high-pass filter 603.

[0102] According to an embodiment, at least one processor 120 may generate a second vibration sound signal through a filter. The second vibration sound signal may be generated based on recognizing that the ambient sound is below a threshold. For example, at least one processor 120 may set the pass frequency of the high pass filter 603 to a second pass frequency to generate the second vibration sound signal. At least one processor 120 may generate the second vibration sound signal based on the audio signal passing through the high pass filter 603. The second vibration sound signal may have a lower sense of heterogeneity than the first vibration sound signal. The first pass frequency may be higher than the second pass frequency.

According to an embodiment, at least one processor 120 may generate the vibration sound signal through a plurality of filters.

[0104] exist Figure 6 In the embodiment, it is described that the second frequency signal generating the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency.

According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0106] exist Figure 6, it is described that a vibration sound signal is generated using a high-pass filter, but the embodiments of the present disclosure are not limited thereto. According to an embodiment, at least one processor 120 may generate a vibration sound signal through a variable filter. For example, at least one processor 120 may generate a vibration sound signal through a high-pass filter, a low-pass filter, or a band-pass filter. According to an embodiment, at least one processor 120 may generate a vibration sound signal through a low-pass filter. For example, at least one processor 120 may generate a first vibration sound signal through a low-pass filter. The first vibration sound signal may be generated based on recognizing that the ambient sound is greater than or equal to a threshold. For example, at least one processor 120 may set the pass frequency of the low-pass filter to a first pass frequency to generate the first vibration sound signal. At least one processor 120 may generate a first vibration sound signal based on an audio signal passing through a low-pass filter. The first vibration sound signal may have a higher transmission property than the second vibration sound signal. For example, at least one processor 120 may generate a second vibration sound signal through a low-pass filter. The second vibration sound signal may be generated based on recognizing that the ambient sound is lower than a threshold. For example, at least one processor 120 may set the pass frequency of the low-pass filter to a second pass frequency to generate a second vibration sound signal. At least one processor 120 may generate a second vibration sound signal based on the audio signal passing through a low pass filter. The first pass frequency in the low pass filter may be higher than the second pass frequency in the low pass filter. The second vibration sound signal may have a lower sense of heterogeneity than the first vibration sound signal.

[0107] Figure 7 An example of a configuration of a first vibration sound signal and a configuration of a second vibration sound signal according to the embodiment is shown.

[0108] refer to Figure 7 , a first graph 710 indicates that the Figure 3 701 indicates the gain of a first frequency signal (e.g., about 150 Hz). Histogram 703 indicates the gain of a second frequency signal (e.g., about 300 Hz). Histogram 705 indicates the gain of a third frequency signal (e.g., about 450 Hz). Histogram 707 indicates the gain of a fourth frequency signal (e.g., about 600 Hz).

[0109] According to an embodiment, the first vibration sound signal may be generated by synthesizing the first frequency signal, the second frequency signal, the third frequency signal and / or the fourth frequency signal. In the case where the intensity of the ambient sound received by the microphone 307 is greater than or equal to the threshold, the first vibration sound signal may be generated. The motor (e.g., Figure 3The frequency of the vibration sound of the motor 303) may be about 150 Hz. Within about 150 Hz to about 600 Hz, when the frequency of the first vibration sound signal becomes higher, the user can better hear the first vibration sound signal. Therefore, when the sound pressure of the third frequency signal (e.g., histogram 705) and the sound pressure of the fourth frequency signal (e.g., histogram 707) are large, the user can better hear the first vibration sound signal compared to the case where the sound pressure 705 of the third frequency signal and the sound pressure 707 of the fourth frequency signal are small. In the case where the intensity of the ambient sound is greater than or equal to the threshold, increasing the transmissibility of the first vibration sound signal can improve the user experience compared to reducing the heterogeneity of the first vibration sound. This is because the transmissibility of the basic sound cannot be ensured when the intensity of the ambient sound is greater than or equal to the threshold. Therefore, in the case where the intensity of the ambient sound is greater than the threshold, the sound pressure 705 of the third frequency signal and the sound pressure 707 of the fourth frequency signal may be greater than the sound pressure of the first frequency signal (e.g., histogram 701) and the sound pressure of the second frequency signal (e.g., histogram 703). Reducing the sound pressure 701 of the first frequency signal and the sound pressure 703 of the second frequency signal can be used to improve the transmissibility of the speaker, reduce the current consumption of the speaker and / or reduce the heating of the speaker. This is because even if the same power is used, increasing the sound pressure 705 of the third frequency signal and the sound pressure 707 of the fourth frequency signal can have higher transmissibility to the user than increasing the sound pressure 701 of the first frequency signal and the sound pressure 703 of the second frequency signal. By increasing the sound pressure 701 of the first frequency signal and the sound pressure 703 of the second frequency signal to improve transmissibility, more power may be consumed compared to increasing the sound pressure 705 of the third frequency signal and the sound pressure 707 of the fourth frequency signal. In the case of consuming a large amount of power, the speaker coil may heat more than in the case of consuming a small amount of power. The first vibration sound signal may have higher transmissibility than the second vibration sound signal.

[0110] The second graph 720 indicates the noise below the threshold (e.g., ambient sound) received by the microphone 307 and the signal strength of each frequency. The histogram 709 indicates the gain of the first frequency signal (e.g., about 150 Hz). The histogram 711 indicates the gain of the second frequency signal (e.g., about 300 Hz). The histogram 713 indicates the gain of the third frequency signal (e.g., about 450 Hz). The histogram 715 indicates the gain of the fourth frequency signal (e.g., about 600 Hz).

[0111] According to an embodiment, a second vibration sound signal may be generated by synthesizing a first frequency signal, a second frequency signal, a third frequency signal, and / or a fourth frequency signal. In the case where the intensity of the ambient sound received by the microphone 307 is lower than a threshold value, a second vibration sound signal may be generated. The frequency of the vibration sound of the motor 303 may be about 150 Hz. Within about 150 Hz to about 600 Hz, when the frequency of the second vibration sound signal becomes lower, the sense of heterogeneity between the vibration of the motor 303 and the second vibration sound signal may be reduced. When the sound pressure of the first frequency signal (e.g., histogram 709) and the sound pressure of the second frequency signal (e.g., histogram 711) are large, the sense of heterogeneity may be reduced compared to the case where the sound pressure 709 of the first frequency signal and the sound pressure 711 of the second frequency signal are small. In the case where the intensity of the ambient sound is lower than a threshold value, reducing the sense of heterogeneity of the second vibration sound signal may improve the user experience compared to improving the transmissibility of the second vibration sound signal. This is because the transmissibility of the basic sound is ensured when the intensity of the ambient sound is lower than a threshold value. Therefore, when the intensity of the ambient sound is lower than the threshold, the sound pressure of the third frequency signal (e.g., histogram 713) and the sound pressure of the fourth frequency signal (e.g., histogram 715) may be lower than the sound pressure of the first frequency signal 709 and the sound pressure of the second frequency signal 711. The second vibration sound signal may have a lower sense of heterogeneity than the first vibration sound signal.

[0112] According to one embodiment, the amplifier for generating an audio signal may release amplitude control and perform temperature control to generate a second vibration sound signal. The amplifier for generating an audio signal may release amplitude control to generate a second vibration sound signal. The amplifier for generating an audio signal may perform temperature control to generate a second vibration sound signal. When an audio signal having a frequency less than or equal to a reference value is input, the amplifier for generating an audio signal may reduce the amplitude of the input audio signal through amplitude control. When the amplitude control is released, the amplifier may not reduce the amplitude even if an audio signal having a frequency less than or equal to the reference value is input. Therefore, at least one processor may generate a second vibration sound signal by using a frequency signal of a relatively low frequency band. Even if the amplitude control is released, at least one processor 120 may maintain temperature control. It may be based on a control signal included in a speaker (e.g., Figure 3 The temperature control is performed based on the temperature of the coil in the speaker 309. Based on the temperature of the coil being greater than or equal to the reference value, the at least one processor 120 may perform an operation for reducing the temperature of the coil.

[0113] According to an embodiment, an electronic device (e.g., Figure 1The electronic device 101 of the embodiment of the present invention can utilize the space behind the speaker 309 in the electronic device as a space for resonating the sound of the speaker 309. When the space behind the speaker 309 is divided into the rear cover glass of the electronic device, the rear cover glass can vibrate by the vibration sound signal. In order to enable the user to better detect the vibration sound signal, the at least one processor 120 can generate the vibration sound signal so that the vibration of the rear cover glass is greater.

[0114] exist Figure 7 In the embodiment, it is described that the second frequency signal generating the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. In other words, the second frequency may not be a harmonic frequency of the first frequency.

[0115] exist Figure 7 In the embodiment, it is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0116] Figure 8 The operation flow of an electronic device for generating a first vibration sound signal or a second vibration sound signal according to an embodiment is shown. The vibration sound signal may refer to a signal generated based on a signal having a vibration frequency of a motor and a signal having a frequency that is a multiple of the vibration frequency of the motor. In the case where the intensity of the signal having the vibration frequency of the motor is less than the intensity of the signal having a frequency that is a multiple of the vibration frequency of the motor, the vibration sound signal may be referred to as a first vibration sound signal. In the case where the intensity of the signal having the vibration frequency of the motor is greater than the intensity of the signal having a frequency that is a multiple of the vibration frequency of the motor, the vibration sound signal may be referred to as a second vibration sound signal.

[0117] refer to Figure 8 In operation 801, at least one processor 120 may identify a control signal for operating a motor. According to an embodiment, a motor (e.g., Figure 3The motor 303 of the electronic device 301 may be operated to provide a notification to the user by vibration. For example, the motor 303 may be operated to provide a call reception notification to the user by vibration. For example, the motor 303 may be operated to provide a message window notification to the user by vibration. For example, the motor 303 may be operated to provide an alarm notification to the user by vibration. According to an embodiment, the vibration of the motor 303 may be detected by the user using the sense of touch. The vibration sound signal generated by the motor 303 may have a small intensity. Even if the motor 303 is operated, the user may not be able to detect the vibration using the sense of hearing. Therefore, when the electronic device 301 is not in contact with the user, the user may not be able to detect the vibration of the motor 303.

[0118] In operation 803, at least one processor 120 may identify the strength of the sound input through the microphone based on the recognition control signal. At least one processor 120 may identify the strength of the sound input through the microphone (e.g., Figure 3 The microphone 307) recognizes the intensity of the ambient sound to generate a vibration sound signal.

[0119] In operation 805, the at least one processor 120 may identify whether the intensity of the sound input through the microphone is greater than or equal to a threshold value. In the case where the intensity of the sound input through the microphone is greater than or equal to the threshold value, the at least one processor 120 may perform operation 807. In the case where the intensity of the sound input through the microphone is lower than the threshold value, the at least one processor 120 may perform operation 809. According to an embodiment, the at least one processor 120 may identify the intensity of the sound input through the microphone 307, and transmit the sound through the speaker (e.g., Figure 3 309) generates a vibration sound signal. For example, in a case where the intensity of the sound input through the microphone 307 is greater than or equal to a threshold value, the at least one processor 120 may generate a first vibration sound signal based on a first frequency signal according to a first sound pressure and a second frequency signal according to a second sound pressure. The first sound pressure may be less than the second sound pressure. The second frequency of the second frequency signal may be a multiple of the first frequency of the first frequency signal. For example, in a case where the intensity of the sound is lower than a threshold value, the at least one processor 120 may generate a second vibration sound signal based on a first frequency signal according to a third sound pressure and a second frequency signal according to a fourth sound pressure. The third sound pressure may be greater than the fourth sound pressure. The average frequency of the first vibration sound signal may be higher than the average frequency of the second vibration sound signal.

[0120] In operation 807, at least one processor 120 may generate a first vibration sound signal based on a first frequency signal according to a first sound pressure and a second frequency signal according to a second sound pressure. For example, in at least one processor 120, when the intensity of the sound input through the microphone 307 is greater than or equal to a threshold, the first sound pressure may be less than the second sound pressure. At least one processor 120 may set the second sound pressure to be higher than the first sound pressure so as to improve the transmissibility of the vibration sound signal generated based on the first frequency signal and the second frequency signal, reduce current consumption, and reduce the heating of the speaker. This is because even if the same current is used, increasing the second sound pressure of the second frequency signal may have a higher transmissibility to the user than increasing the first sound pressure of the first frequency signal. By increasing the first sound pressure to improve the transmissibility, more power may be consumed compared to the case of increasing the second sound pressure. In the case of consuming a large amount of power, the speaker coil may generate more heat than the case of consuming a small amount of power.

[0121] In operation 809, at least one processor 120 may generate a second vibration sound signal based on a first frequency signal according to a third sound pressure and a second frequency signal according to a fourth sound pressure. For example, in at least one processor 120, when the intensity of the sound input through the microphone 307 is lower than a threshold, the third sound pressure may be greater than the fourth sound pressure. At least one processor 120 may set the third sound pressure to be higher than the fourth sound pressure so as to reduce the heterogeneity between the vibration sound signal generated based on the first frequency signal and the second frequency signal and the vibration of the motor 303. When the intensity of the ambient sound is lower than the threshold, reducing the heterogeneity of the second vibration sound signal can improve the user experience compared to improving the transmissibility of the second vibration sound signal. This is because the transmissibility of the basic sound is ensured when the intensity of the ambient sound is lower than the threshold.

[0122] Figure 8 The intensity of the sound input through the microphone is identified based on identifying the control signal for operating the motor, but the embodiments of the present disclosure are not limited thereto. According to an embodiment, the intensity of the sound input through the microphone can be identified based on identifying the control signal for generating the first vibration sound signal or the second vibration sound signal.

[0123] exist Figure 8 In the embodiment, it is described that the second frequency signal generating the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. In other words, the second frequency may not be a harmonic frequency of the first frequency.

[0124] exist Figure 8In the embodiment, it is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0125] Fig. 9 An operation flow of an electronic device for adjusting the intensity of a vibration sound signal according to whether a phone application is running according to an embodiment is shown.

[0126] refer to Fig. 9 In operation 901, at least one processor 120 may recognize that a phone application is running. For example, a user may use an electronic device (e.g., Figure 1 The electronic device 101) performs a telephone call.

[0127] In operation 903, at least one processor 120 may identify whether a control signal for operating the received motor is received while the phone application is running. In the case where a control signal for operating the received motor is received while the phone application is running, at least one processor 120 may perform operation 905. In the case where a control signal for operating the received motor is not received while the phone application is running, at least one processor 120 may perform operation 907. According to an embodiment, when the user is using the phone application, a message window notification through vibration may be provided to the user. According to another embodiment, when the user is using the phone application, an alarm notification may be provided to the user. When the phone application is running, the probability that the user is at a short distance from the electronic device 101 is high. In addition, when the phone application is running, the probability that the user is in a state of contact with the electronic device 101 is high. A high-intensity vibration sound signal generated in a state where the user is in contact with the electronic device 101 may reduce the user experience. Therefore, at least one processor 120 may adjust the intensity of the vibration sound signal (e.g., the first vibration sound signal and / or the second vibration sound signal) according to whether the phone application is running.

[0128] In operation 905, at least one processor 120 may generate a first vibration sound signal or a second vibration sound signal having a first intensity. According to an embodiment, the processor 305 may set the intensity of the vibration sound signal (e.g., the first vibration sound signal or the second vibration sound signal) to be lower than the intensity of the vibration sound signal when the phone application is not running.

[0129] In operation 907, at least one processor 120 may generate a first vibration sound signal or a second vibration sound signal having a second intensity. The second intensity may be greater than the first intensity. This is because a vibration sound signal of high intensity generated when the user is in contact with the electronic device 101 may reduce the user experience.

[0130] exist Fig. 9 In the embodiment, it is described that the second frequency signal used to generate the vibration sound signal is a multiple of the first frequency signal, but the embodiments of the present disclosure may not be limited thereto. According to an embodiment, the second frequency may not be a multiple of the first frequency. At least one processor 120 may generate a vibration sound signal based on a first frequency signal having a first frequency and a second frequency signal having a second frequency. In other words, the second frequency may not be a harmonic frequency of the first frequency.

[0131] exist Fig. 9 In the embodiment, it is described that the vibration sound signal is generated based on two frequency signals, but the embodiments of the present disclosure may not be limited thereto. According to the embodiment, the vibration sound signal may be generated based on multiple frequency signals including a first frequency signal and a second frequency signal. The multiple frequency signals may be three or more.

[0132] Fig.10 A flow of an operation of an electronic device for adjusting a vibration sound signal according to an electronic device recognized as to be used by a sensor according to an embodiment is shown.

[0133] refer to Fig.10 In operation 1001, at least one processor (eg, Figure 1 The processor 120 may identify a device for operating a motor (eg, Figure 3 According to an embodiment, the motor 303 may be operated to provide a notification to the user by vibration. For example, the motor 303 may be operated to provide a call reception notification to the user by vibration. For example, the motor 303 may be operated to provide a message window notification to the user by vibration. For example, the motor 303 may be operated to provide an alarm notification to the user by vibration. According to an embodiment, the vibration of the motor 303 may be detected by the user using the sense of touch. The vibration sound signal generated by the motor 303 may have a small intensity. Even if the motor 303 is operated, the user may not be able to detect the vibration by hearing. Therefore, when the electronic device 301 is not in contact with the user, the user may not be able to detect the vibration of the motor 303.

[0134] In operation 1003, at least one processor 120 may identify an electronic device (eg, Figure 3 The electronic device 301 is in use. The at least one sensor may be a proximity sensor. The at least one sensor may detect that the user's body is within a predetermined range from the electronic device.

[0135] In operation 1005, at least one processor 120 may generate a second vibration sound signal. This is because even if the intensity of the sound input through the microphone is greater than or equal to the threshold, if the user is at a short distance, the need to increase the transmissibility of the sound is low. When the electronic device 301 is in use, the probability that the user is within a short distance from the electronic device 301 is high. In addition, when the electronic device 301 is in use, the probability that the user is in contact with the electronic device 301 is high. Therefore, in the case where a control signal for operating the motor 303 is recognized when the electronic device 301 is used, the processor 305 may generate a second vibration sound signal because the need to increase the transmissibility of the sound is low.

[0136] As described above, the electronic device 101 or 301 according to the embodiment may include at least one processor 120 or 305, a microphone 307, a speaker 309, and a motor 303. The electronic device 101 or 301 may include at least one processor 120 or 305. The electronic device 101 or 301 may include a microphone 307. The electronic device 101 or 301 may include a speaker 309. The electronic device 101 or 301 may include a motor 303.

[0137] The first vibration sound signal according to the embodiment may be generated by synthesizing the first frequency signal and the second frequency signal. The second vibration sound signal may be generated by synthesizing the second frequency signal and the second frequency signal. The second frequency of the second frequency signal may be a multiple of the first frequency of the first frequency signal.

[0138] The electronic device 101 or 301 according to the embodiment may further include a high pass filter 603. In order to generate a vibration sound signal, at least one processor 120 or 305 may be configured to: when the intensity of the sound input by the microphone 307 is greater than or equal to the threshold, the pass frequency of the high pass filter 603 is set to the first pass frequency. At least one processor 120 or 305 may generate a first vibration sound signal based on the audio signal passing through the high pass filter 603.

The intensity of the sound input through the microphone 307 may be identified based on the control signal for generating the first vibration sound signal or the second vibration sound signal.

[0140] An average frequency of the first vibration sound signal may be higher than an average frequency of the second vibration sound signal.

[0141] At least one processor 120 or 305 according to an embodiment may also be configured to recognize that the electronic device 101 or 301 is running a phone application. In order to generate a first vibration sound signal or a second vibration sound signal, at least one processor 120 or 305 may be configured to: generate a first vibration sound signal or a second vibration sound signal with a first intensity based on the control signal for operating the motor 303 received when the phone application is running.
