[0027] Figure 4 This is a flowchart of a recording method for an electronic device according to an embodiment of the present disclosure. Detailed Implementation

[0028] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0029] The electronic device 1 according to an embodiment of the present disclosure is described below with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, the electronic device 1 according to an embodiment of the present disclosure includes a body 10, a first microphone 20, and a processor 30.

[0030] The body 10 has a first plate 11 and a second plate 12 disposed opposite to each other, defining a receiving cavity 13 between the first plate 11 and the second plate 12. A first microphone 20 includes a capacitor 21 located within the receiving cavity 13. The capacitor 21 includes a first conductive film 211 and a second conductive film 212, the first conductive film 211 being disposed on the first plate 11 and the second conductive film 212 being disposed on the second plate 12. A processor 30 is used to acquire an audio signal based on a current signal generated by a change in the spacing between the first conductive film 211 and the second conductive film 212.

[0031] By placing the first conductive film 211 on the first plate 11 and the second conductive film 212 on the second plate 12, when vibrations caused by sound cause a change in the distance between the first plate 11 and the second plate 12, the distance between the first conductive film 211 and the second conductive film 212 will also change. This causes a change in the capacitance of the capacitor 21, thereby generating a changing current (electrical signal, audio signal). The analog-to-digital converter circuit of the processor 30 can convert the changing current into a digital signal to obtain audio data, thereby realizing recording.

[0032] Because the rigidity of the first plate 11 and the second plate 12 of the body 10 of the electronic device 1 is much greater than that of the diaphragm of the MEMS microphone, the change in the distance between the first plate 11 and the second plate 12 is much smaller than the change in the distance between the diaphragm and the back plate of the MEMS microphone under the action of sound at the same sound pressure level. Therefore, when the sound pressure level is high, the sound recorded by the MEMS microphone will be distorted, while the sound recorded by the capacitor 21 (first microphone 20) provided on the first plate 11 and the second plate 12 will not be distorted.

[0033] According to the embodiments of the present disclosure, the electronic device 1 can record sounds with high sound pressure levels by disposing the first conductive film 211 and the second conductive film 212 of the first microphone 20 on the first plate 11 and the second plate 12, respectively. In this way, the first microphone 20 can be used to record sounds with high sound pressure levels and can obtain low-distortion recording effects, that is, to obtain low-distortion recording effects under high sound pressure levels.

[0034] Therefore, the electronic device 1 according to the embodiments of this disclosure has advantages such as good recording effect at high sound pressure level.

[0035] The electronic device 1 according to embodiments of this disclosure may be a mobile phone, tablet computer, voice recorder, etc. Figure 1 and Figure 2 As shown, the electronic device 1 may include a body 10, a first microphone 20, a processor 30, and a second microphone 40.

[0036] The main body 10 may include a front shell 114, a middle frame 115, and a rear cover 116, wherein one of the front shell 114 and the rear cover 116 is a first plate 11, and the middle frame 115 is a second plate 12. The first microphone 20 includes a capacitor 21, which includes a first conductive film 211 and a second conductive film 212.

[0037] like Figure 1As shown, capacitor 21 is located within receiving cavity 13. A first conductive film 211 is disposed on one of the front shell 114 and rear cover 116, and a second conductive film 212 is disposed on the middle frame 115. Specifically, the first conductive film 211 can be bonded to one of the front shell 114 and rear cover 116 (first plate 11), and the second conductive film 212 can be bonded to the middle frame 115 (second plate 12).

[0038] Optionally, the first conductive film 211 is a first metal film, and the second conductive film 212 is a second metal film.

[0039] Optionally, the area of ​​the first conductive film 211 is equal to the area of ​​the second conductive film 212. This makes the structure of the first microphone 20 more reasonable.

[0040] The area of ​​the first conductive film 211 is greater than or equal to 8 square centimeters and less than or equal to 30 square centimeters, and the area of ​​the second conductive film 212 is greater than or equal to 8 square centimeters and less than or equal to 30 square centimeters. Because the first plate 11 and the second plate 12 have relatively high rigidity, this can negatively impact the sensitivity of the first microphone 20. By making the first conductive film 211 and the second conductive film 212 have larger areas (8 square centimeters to 30 square centimeters), the sensitivity of the first microphone 20 can be improved.

[0041] In one embodiment of this disclosure, a first conductive film 211 is disposed in the middle of the front shell 114, and a second conductive film 212 is disposed in the middle of the middle frame 115. The area of ​​the first conductive film 211 is greater than or equal to 18 square centimeters and less than or equal to 23 square centimeters, and the area of ​​the second conductive film 212 is greater than or equal to 18 square centimeters and less than or equal to 23 square centimeters. This not only improves the sensitivity of the first microphone 20 but also reduces the space occupied by the capacitor 21 (first microphone 20), thereby reducing the installation difficulty of the first microphone 20 and contributing to a smaller size of the electronic device 1.

[0042] Optionally, the area of ​​the first conductive film 211 is 20 square centimeters, and the area of ​​the second conductive film 212 is 20 square centimeters. This not only improves the sensitivity of the first microphone 20, but also reduces the space occupied by the capacitor 21 (first microphone 20), thereby reducing the installation difficulty of the first microphone 20 and helping to reduce the size of the electronic device 1.

[0043] In another embodiment of this disclosure, the battery (not shown) of the electronic device 1 is disposed on the middle frame 115, the first conductive film 211 is disposed on the back cover 116 (first plate 11), and the second conductive film 212 is disposed on the battery (second plate 12), that is, the second conductive film 212 is disposed on the middle frame 115 through the battery. The area of ​​the first conductive film 211 is greater than or equal to 8 square centimeters and less than or equal to 12 square centimeters, and the area of ​​the second conductive film 212 is greater than or equal to 8 square centimeters and less than or equal to 12 square centimeters. This allows for a reduction in the space occupied by the capacitor 21 (first microphone 20) while ensuring the sensitivity of the first microphone 20, thereby reducing the installation difficulty of the first microphone 20 and contributing to a reduction in the size of the electronic device 1.

[0044] Optionally, the area of ​​the first conductive film 211 is 10 square centimeters, and the area of ​​the second conductive film 212 is 10 square centimeters. This allows for a reduction in the space occupied by the capacitor 21 (first microphone 20) while ensuring the sensitivity of the first microphone 20, thereby reducing the installation difficulty of the first microphone 20 and helping to reduce the size of the electronic device 1.

[0045] The area of ​​the first conductive film 211 refers to the area of ​​the surface of the first conductive film 211 opposite to the second conductive film 212; the area of ​​the second conductive film 212 refers to the area of ​​the surface of the second conductive film 212 opposite to the first conductive film 211. For example, when the first conductive film 211 and the second conductive film 212 are spaced apart in the vertical direction, and the first conductive film 211 is located above the second conductive film 212, the area of ​​the first conductive film 211 refers to the area of ​​its lower surface, and the area of ​​the second conductive film 212 refers to the area of ​​its upper surface.

[0046] The thickness of the first conductive film 211 is greater than or equal to 0.5 micrometers and less than or equal to 10 micrometers, and the thickness of the second conductive film 212 is greater than or equal to 0.5 micrometers and less than or equal to 10 micrometers. The distance between the first conductive film 211 and the second conductive film 212 in the thickness direction of the first conductive film 211 is greater than or equal to 0.1 millimeters and less than or equal to 0.3 millimeters.

[0047] The thickness directions of the first conductive film 211, the second conductive film 212, and the electronic device 1 are aligned. This allows for a more reasonable dimension of the capacitor 21 (first microphone 20) in the thickness direction of the electronic device 1, thus fully utilizing the existing space between the front cover 114 and the rear cover 116 and the middle frame 115. This avoids increasing the thickness of the electronic device 1 due to the installation of the first microphone 20, thereby enabling high sound pressure level recording while effectively utilizing the existing spacing between devices.

[0048] Optionally, the thickness of the first conductive film 211 is equal to the thickness of the second conductive film 212.

[0049] In one embodiment of this disclosure, a first microphone 20 and a second microphone 40 are switchably connected to a processor 30 so that the processor 30 can switchably receive one of the audio signals (electrical signals) transmitted by the first microphone 20 and the audio signals (electrical signals) transmitted by the second microphone 40.

[0050] When recording a sound with a high sound pressure level, the first microphone 20 can be connected to the analog-to-digital converter circuit of the processor 30 so that the analog-to-digital converter circuit of the processor 30 can receive the audio signal sent by the first microphone 20. Then, the analog-to-digital converter circuit of the processor 30 converts the audio signal sent by the first microphone 20 into a digital signal to obtain the audio data of the first microphone 20. The processor 30 outputs the audio data of the first microphone 20 to realize the recording.

[0051] When recording a sound at a low sound pressure level, the second microphone 40 can be connected to the analog-to-digital converter circuit of the processor 30 so that the analog-to-digital converter circuit of the processor 30 can receive the audio signal sent by the second microphone 40. Then, the analog-to-digital converter circuit of the processor 30 converts the audio signal sent by the second microphone 40 into a digital signal to obtain the audio data of the second microphone 40. The processor 30 outputs the audio data of the second microphone 40 to realize the recording.

[0052] In another embodiment of this disclosure, each of the first microphone 20 and the second microphone 40 is connected to the processor 30 so that the processor 30 can switchably output audio data of one of the first microphone 20 and the second microphone 40.

[0053] Since each of the first microphone 20 and the second microphone 40 is connected to the processor 30, the analog-to-digital converter (ADC) circuit of the processor 30 can receive audio signals transmitted by each of the first microphone 20 and the second microphone 40. When recording a sound pressure level (SPL), the ADC circuit of the processor 30 converts the audio signal transmitted by the first microphone 20 into a digital signal to obtain the audio data of the first microphone 20. The processor 30 outputs the audio data of the first microphone 20 to achieve recording. At this time, the ADC circuit of the processor 30 does not convert the audio signal transmitted by the second microphone 40. When recording a sound pressure level (SPL), the ADC circuit of the processor 30 converts the audio signal transmitted by the second microphone 40 into a digital signal to obtain the audio data of the second microphone 40. The processor 30 outputs the audio data of the second microphone 40 to achieve recording. At this time, the ADC circuit of the processor 30 does not convert the audio signal transmitted by the first microphone 20.

[0054] By setting up a first microphone 20 and a second microphone 40, the electronic device 1 can record not only sounds with high sound pressure levels but also sounds with low sound pressure levels while ensuring low-distortion recording effects, thus expanding its application scenarios. Therefore, the electronic device 1 has advantages such as good recording effects and a wide recording range.

[0055] Optionally, the second microphone 40 is a MEMS microphone. The second microphone 40 can be a conventional microphone, and the second microphone 40 can be installed within the body 10 in a known manner. For example, the second microphone 40 can be installed at the bottom or top of the body 10.

[0056] The electronic device 1 disclosed herein has advantages such as good recording effect and wide recording range. While ensuring low distortion recording effect, it can record not only sounds with high sound pressure level, but also sounds with low sound pressure level.

[0057] This disclosure also provides a recording method for an electronic device 1 including a first microphone 20. For example... Figure 3 As shown, the recording method of the electronic device 1 according to an embodiment of this disclosure includes the following steps:

[0058] Start the recording function; and

[0059] The processor outputs audio data from the first microphone.

[0060] By utilizing the recording method of the electronic device 1 according to embodiments of the present disclosure, the electronic device 1 can record sounds with high sound pressure levels while maintaining low-distortion recording quality. Therefore, the recording method of the electronic device 1 according to embodiments of the present disclosure has advantages such as good high sound pressure level sound recording effect.

[0061] This disclosure also provides a recording method for an electronic device 1 including a first microphone 20 and a second microphone 40. For example... Figure 4 As shown, the recording method of the electronic device 1 according to an embodiment of this disclosure includes the following steps:

[0062] Start the recording function; and

[0063] The processor 30 detects the sound pressure level. When the sound pressure level is greater than or equal to a preset value, the processor 30 outputs the audio data of the first microphone 20. When the sound pressure level is less than the preset value, the processor 30 outputs the audio data of the second microphone 40.

[0064] By utilizing the recording method of the electronic device 1 according to embodiments of the present disclosure, the electronic device 1 can record not only sounds with high sound pressure levels but also sounds with low sound pressure levels while ensuring low-distortion recording effects. Therefore, the recording method of the electronic device 1 according to embodiments of the present disclosure has advantages such as good recording effect and wide recording range.

[0065] Optionally, the preset value is 120dB. That is, when the sound pressure level is detected to be greater than or equal to 120dB, the processor 30 outputs the audio data of the first microphone 20; when the sound pressure level is detected to be less than 120dB, the processor 30 outputs the audio data of the second microphone 40.

[0066] The sound pressure level can be obtained based on the output current of at least one of the first microphone 20 and the second microphone 40. Preferably, the sound pressure level value is obtained based on the output current (audio signal) of each of the first microphone 20 and the second microphone 40.

[0067] Specifically, each of the first microphone 20 and the second microphone 40 is connected to the analog-to-digital converter (ADC) circuit of the processor 30, so that the ADC circuit of the processor 30 can receive the output current of each of the first microphone 20 and the second microphone 40. The processor 30 can obtain the sound pressure level value based on the output current of each of the first microphone 20 and the second microphone 40. According to the relationship between the sound pressure level and the preset value, the ADC circuit of the processor 30 converts the audio signal (output current) sent by the corresponding one of the first microphone 20 and the second microphone 40 into a digital signal to obtain audio data. The processor 30 outputs the audio data to realize recording.

[0068] This ensures that the analog-to-digital conversion circuit of the processor 30 always receives audio signals from both the first microphone 20 and the second microphone 40, thus preventing any gaps when switching the output of audio data from either the first microphone 20 or the second microphone 40. In other words, there are no gaps when switching from outputting audio data from the first microphone 20 (second microphone 40) to outputting audio data from the second microphone 40 (first microphone 20).
