When the electronic device is relatively close to the human head, for example, when the relative position between the electronic device and the human head is within the first position range, the sound emitted by the first sound unit 10 can be controlled to be reduced, and since it is relatively close, it does not affect the user's call; and / or, when the electronic device is far from the human head, for example, when the relative position between the electronic device and the human head is within the second position range, the sound emitted by the second sound unit can be controlled to be increased, and the sound of the first sound unit 10 can also be reduced to better prevent sound leakage.

[0108] like Fig.19 As shown, an embodiment of the present application provides a control device for an electronic device, comprising:

[0109] A detection module 90, configured to detect status information, wherein the status information includes at least one of a sound of an external environment and a relative position between the electronic device and a human head;

[0110] The control module 91 is used to control the volume of the sound emitted by the first sound unit 10 and the second sound unit 20 according to the state information. During use, the state information is detected by the detection module 90. In a noisy environment, the control module 91 can be used to control the volume of the sound emitted by the first sound unit 10 to increase according to the state information, thereby enhancing the user's call experience. In a quiet environment, the control module 91 can be used to control the volume of the sound emitted by the second sound unit 20 to increase according to the state information, thereby reducing the sound of the first sound unit 10, thereby better achieving the purpose of preventing sound leakage.

[0111] In some embodiments, the control module 91 is used to control the sound emitted by the first sound unit 10 to increase when the sound of the external environment is greater than a first volume threshold; and / or, the control module 91 is used to control the sound emitted by the second sound unit 20 to increase and / or control the sound emitted by the first sound unit 10 to decrease when the sound of the external environment is less than a second volume threshold.

[0112] Optionally, the control module 91 is used to control the sound emitted by the first sound unit 10 to decrease when the relative position between the electronic device and the human head is within a first position range; and / or, the control module 91 is used to control the sound emitted by the second sound unit 20 to increase when the relative position between the electronic device and the human head is within a second position range.

[0113] During the application process, Figures 17a to 17d As shown in the figure, during a call, the user presents different postures, and the face reflects the sound, causing sound leakage. Theoretically, in a mobile phone-shaped product, the position design of the sound hole will not have much impact on the direction of sound propagation, because the human voice is mainly concentrated in 300-3400Hz, the wavelength is between 1.13-0.1m, and its size is much larger than the appearance of the mobile phone, so the sound will basically be diffracted. However, based on the different coordination between the sound hole of the mobile phone and the human ear, and the different postures of each person holding the mobile phone, the size of the sound leakage will be slightly different. If the sound hole of the mobile phone earpiece is closer to the top, it will not be very tight when coupled with the human ear, and the sound leakage will increase. In addition, if the mobile phone is closer to the ear during the call, the sound leakage can also be reduced to a certain extent.

[0114] Through the sound of the first sound unit 10 (such as a handset) and the second sound unit 20 (such as piezoelectric ceramics), sound leakage prevention is achieved in different scene combinations. The front sound cavity of the handset can only emit low-frequency sounds below 500hz (customizable frequency band, which can be controlled by parameters). Piezoelectric ceramics can only emit medium and high-frequency sounds above 500hz (customizable frequency band, which can be controlled by parameters). The leakage hole 51 can emit low-frequency sounds below 500hz, which is in the opposite phase to the sound emitted by the front sound cavity of the handset. During use, it is detected whether it is in a noisy environment. If it is in a noisy environment (various sounds are mixed together, and the leakage components of the handset and the noise of the environment are mixed together and are not easy to hear clearly), the sound volume of the first sound unit 10 (such as a handset) can be automatically increased without leaking sound, thereby enhancing the user's call experience. If in a quiet environment (if there is sound leakage, it is easy for other people nearby to perceive the leaked sound information), the sound volume of the second sound unit 20 (such as piezoelectric ceramics) can be increased, and the sound of the first sound unit 10 (such as the earpiece) can be reduced; thereby better achieving the purpose of preventing sound leakage. The detection module can detect the sound of the surrounding environment, and then control the increase or decrease of the volume of the sound unit.

[0115] The low-frequency signal of the front sound cavity of the earpiece reflected by the human head and the low-frequency signal leaked by the leakage hole 51 are exactly opposite in phase, and can be offset, and the low-frequency component is almost inaudible from a distance. The second sound unit 20 can be a piezoelectric ceramic, which drives the display screen to emit medium and high frequency signals above 500Hz. Since the piezoelectric ceramic is attached to the display screen, under the action of the shockproof structure 63, the medium and high frequencies will hardly leak. Due to the frequency division function of the first sound unit 10 and the second sound unit 20, as well as the role of the leakage hole 51 on the back cover, the low-frequency components can be almost eliminated through the phase, and the medium and high frequency components will not leak, thereby preventing the leakage of sound information and achieving the purpose of preventing sound leakage.

[0116] like Fig.18As shown, ① is the sound of the middle and high frequency components emitted by the second sound unit 20 (such as piezoelectric ceramics) picked up by the human ear (the piezoelectric ceramics are attached to the display screen 40, and the sound leakage on the back is very small; ② is the sound of the low frequency components emitted by the first sound unit 10 (such as the earpiece) picked up by the human ear. Combining ① and ②, the user's own ears can hear the full-band sound without missing the frequency band; ③ is the reflection / diffraction sound of the low frequency sound emitted by the first sound unit 10 (such as the earpiece) by the human face; ④ is the sound emitted by the leakage hole 51 (also a low frequency component), which is exactly opposite to the phase of the sound at ③; the phases of the sounds at ③ and ④ are exactly opposite, and the phases of the sounds at ③ and ④ signals transmitted to A (other people) are canceled, and the low frequency sound is almost inaudible at A. In addition, since the sound ③ emitted by the earpiece only has low frequency components, even if A hears the sound, it is the low frequency component without the high frequency component, and the missing frequency band makes it difficult for A to hear the specific content clearly. The middle and high frequency sound components at ① are due to the second sound unit 20 (compared to Such as piezoelectric ceramics) layout position and the addition of shockproof foam obstruction, fast attenuation; ① the mid-high frequency components cannot reach A, so the mid-high frequency sound components heard at A during the call are very small. Through the above method, the purpose of sound leakage prevention can be achieved. When detecting whether it is a noisy environment, the volume of the first sound unit 10 or the second sound unit 20 can be customized. The sound of the sound unit can also be customized according to the user's usage (hand-held method, close to the head, etc.). The first sound unit 10 and the second sound unit 20 can be combined in different forms to better prevent sound leakage during calls and ensure that the user's information is more secure. This combination scheme can cover many scenarios. Compared with traditional sound leakage prevention schemes, it is more efficient in preventing sound leakage and has a better sound leakage prevention effect. Users can customize the sound frequency bands of different sound units, and can control the frequency bands through several sets of parameters. According to the noisy environment, the sound volume of different sound units can be controlled.
