[0041] Please refer to Figures 1 to 4 , Figures 1 to 4 The electronic equipment 100 provided by the embodiments of the present application can be a mobile phone, a tablet computer, etc. and the following will be introduced by taking the electronic equipment 100 as a mobile phone. The electronic equipment 100 includes a shell 1, a loudspeaker 2 and an audio receiver 3. According to different air tightness detection scenes of the electronic equipment 100, the electronic equipment 100 can include a controller or not.

[0042] Please refer to Figures 1 to 4In the embodiment, the shell 1 is provided with a ventilation hole (not shown in the figure), and a waterproof and breathable film 4 is provided at the ventilation hole; the loudspeaker 2 is arranged in the shell 1, and the controller is electrically connected to the loudspeaker 2, so as to control the loudspeaker 2 to play a preset audio when the temperature of the electronic device 100 reaches a preset temperature threshold; the audio receiver 3 is arranged in the shell 1, and the controller is electrically connected to the audio receiver 3, so as to control the audio receiver 3 to collect a detection audio signal of the electronic device 100 when the ventilation hole is blocked and the loudspeaker 2 plays the preset audio; and the controller is configured to determine an air tightness detection result according to the detection audio signal.

[0043] Specifically, the shell 1 of the electronic device 100 forms an internal space, and the shell 1 is usually provided with a ventilation hole to communicate the internal space of the shell 1 with an external space through the ventilation hole. Please refer to Figure 4 , the waterproof and breathable film 4 is provided at the ventilation hole, the waterproof and breathable film 4 can prevent water from passing through, so that the electronic device 100 has a waterproof function, but the waterproof and breathable film 4 can allow air to pass through, so that the inside of the shell 1 of the electronic device 100 has the same atmospheric pressure as the outside air. If the air tightness of the electronic device 100 is good, the ventilation hole is blocked with putty or the like, so that a completely closed space is formed in the inside of the shell 1 of the electronic device 100; if the air tightness of the electronic device 100 is poor, even if the ventilation hole is blocked with putty or the like, the inside of the shell 1 is still communicated with the external space, so that a completely closed space cannot be formed in the inside of the shell 1.

[0044] The waterproof and breathable film 4 is usually arranged on the inner surface of the shell 1 corresponding to the ventilation hole, and the specific arrangement position of the waterproof and breathable film 4 on the shell 1 can be set according to actual conditions. Optionally, please refer to Figure 4 In the embodiment, the shell 1 includes a battery cover, and the waterproof and breathable film 4 is arranged at the rear camera position of the battery cover.

[0045] The loudspeaker 2 is arranged in the internal space of the shell 1, please refer to Figure 2 and Figure 3 , the loudspeaker 2 usually includes a shell (not shown in the figure) and a sound generating device 23, the inside of the shell forms an acoustic cavity, and the sound generating device 23 is arranged in the acoustic cavity to form a rear acoustic cavity 22 and a front acoustic cavity 24 in the shell, the shell is provided with a damping hole 21, the damping hole 21 is communicated with the rear acoustic cavity 22, so as to communicate the rear acoustic cavity 22 of the loudspeaker 2 with the internal space of the shell 1 through the damping hole 21, and one of the functions of the damping hole 21 is to keep the internal pressure of the rear acoustic cavity 22 of the loudspeaker 2 the same as the internal pressure of the electronic device 100, and the atmospheric pressure of the front acoustic cavity 24 is the same as that of the outside air.

[0046] The audio receiver 3 is arranged in the inner space of the shell 1, the audio receiver 3 can adopt the audio signal of the loudspeaker 2, and the audio receiver 3 can convert the audio signal into an electric signal. The audio receiver 3 can be a component originally arranged on the electronic device 100, for example, a microphone is usually arranged on the electronic device 100, and the audio receiver 3 can be the microphone; or the audio receiver 3 can be a component additionally arranged on the electronic device 100.

[0047] Optionally, referring to FIG. Figure 2 In this embodiment, the audio receiver 3 is arranged on the outer surface of the shell of the loudspeaker 2, so that the audio receiver 3 can more accurately collect the audio signal of the loudspeaker 2.

[0048] Further, referring to FIG. Figure 2 In this embodiment, the audio receiver 3 is arranged close to the sound outlet (not shown in the figure) of the loudspeaker 2, the shell of the loudspeaker 2 is provided with the sound outlet communicating with the front sound cavity 24, and the audio receiver 3 is arranged adjacent to the sound outlet of the loudspeaker 2, so that the audio receiver 3 can more accurately collect the audio signal of the loudspeaker 2.

[0049] The controller can determine the air tightness detection result according to the detection audio signal collected by the audio receiver 3, and the controller can be an audio test device on a production line or a mainboard on the electronic device 100. If the controller is the audio test device on the production line, the controller does not belong to the electronic device 100, that is, the electronic device 100 does not include the controller. If the controller is the mainboard on the electronic device 100, the controller belongs to the electronic device 100, that is, the electronic device 100 includes the controller.

[0050] On the production line, the audio test device on the production line can be selected as the controller, the detection audio signal collected by the audio receiver 3 can be converted into an electric signal and input to the audio test device, the audio test device can obtain the air tightness detection result by analyzing the difference between signals, and the air tightness detection result can be fed back to the production line operator through the audio test device.

[0051] In daily life, the mainboard on the electronic device 100 can be selected as the controller, the detection audio signal collected by the audio receiver 3 can be converted into an electric signal and input to the mainboard, and the mainboard can analyze the difference between signals through a specific algorithm. Optionally, referring to FIG. Figure 1 In this embodiment, the electronic device 100 further includes a screen (not shown in the figure), and the screen is used to display the air tightness detection result, so that the air tightness detection result can be fed back to the consumer by using the screen originally arranged on the electronic device 100.

[0052] In the design and manufacturing process of the electronic device 100 with waterproof performance, all holes and bonding positions on the electronic device 100 are ensured to be sealed, and the inside of the electronic device 100 and the outside form a sealed space. However, in order to ensure that the internal pressure of the electronic device 100 is the same as the external pressure, please refer to Figure 4 The waterproof and breathable film 4 is pasted at the rear camera position of the battery cover of the electronic device 100, and is communicated through the waterproof and breathable film 4. Therefore, in the normal case that the whole machine of the electronic device 100 has good air tightness, without any additional action, the front sound cavity 24 and the rear sound cavity 22 of the loudspeaker 2 are the same as the atmospheric pressure. At this time, the loudspeaker 2 plays the preset audio, the normal audio signal collected by the audio receiver 3 is fed back to the controller, and the normal audio signal is taken as the reference audio signal and stored in the controller.

[0053] In order to simply and quickly detect the air tightness of the whole machine of the electronic device 100, the rubber clay is used to block the air holes of the waterproof and breathable film 4 in communication with the outside. If the air tightness of the electronic device 100 is good, a completely closed space is formed between the inside of the electronic device 100 and the outside. At this time, the electronic device 100 is heated until the temperature reaches a preset temperature threshold (for example, the preset temperature threshold is 50℃, and the preset temperature threshold is 50℃ below will be taken as an example for introduction). Optionally, please refer to Figure 1 In this embodiment, the electronic device 100 is provided with a heating platform 200, and the heating platform 200 is used to heat the electronic device 100. The electronic device 100 can be quickly heated to 50℃ by using the heating platform 200.

[0054] When the electronic device 100 is heated to 50℃, the internal temperature of the electronic device 100 rises, which causes the internal air pressure of the electronic device 100 to increase. Since the internal space of the electronic device 100 is communicated with the rear sound cavity 22 of the loudspeaker 2, the pressure in the rear sound cavity 22 of the loudspeaker 2 becomes larger. Please refer to Figure 5 Figure 5 The internal pressure of the electronic device 100 changes with the temperature in a fixed space. When the room temperature is 20℃, the internal temperature of the electronic device 100 reaches 50℃, and the pressure changes from 1.0*10 5 Pa to 1.102*10 5 Pa. Since the sound generating device 23 is in the sound cavity, when the pressure in the rear sound cavity 22 becomes larger, please refer to Figure 6 , the damping coefficient of the air changes with the change of the pressure. The larger the pressure is, the larger the air damping coefficient is.

[0055] Please refer to Figure 7 ​, the air damping enhances the vibration of the paper cone of the sound production device 23, hinders the movement of the paper cone, and causes sound distortion, especially affecting the 5Hz low-frequency vibration of the sound production device 23, and the distortion in the low-frequency region is particularly serious. At this time, the loudspeaker 2 plays the preset audio, the audio receiver 3 collects the audio signal of the loudspeaker 2 to obtain an abnormal audio signal, which is different from the audio signal (i.e., the reference audio signal) when the waterproof breathable film 4 is not blocked, and the audio receiver 3 can feed back the collected abnormal audio signal to the controller. If the air tightness of the electronic device 100 is poor, when the waterproof breathable film 4 is blocked with putty or the like to block the air holes for communication with the outside, the air pressure inside the electronic device 100 will not change with the increase of temperature, and the audio receiver 3 still receives a normal audio signal, which is the same as the audio signal when the waterproof breathable film 4 is not blocked.

[0056] The controller can determine the air tightness detection result according to the difference between the detected audio signal and the reference audio signal. In this embodiment, if the similarity between the detected audio signal and the reference audio signal is greater than a first similarity threshold, the controller determines that the air tightness detection result is poor air tightness; if the similarity between the detected audio signal and the reference audio signal is less than a second similarity threshold, the controller determines that the air tightness detection result is good air tightness.

[0057] Specifically, the first similarity threshold is not less than the second similarity threshold, and the reference audio signal is an audio signal collected when the air holes are not blocked and the preset audio is played. By comparing the audio curve of the detected audio signal with the audio curve of the reference audio signal, the similarity between the detected audio signal and the reference audio signal is obtained. If the similarity between the detected audio signal and the reference audio signal is high, it means that the detected audio signal is a normal audio signal, indicating that the air tightness of the electronic device 100 is poor; if the similarity between the detected audio signal and the reference audio signal is low, it means that the detected audio signal is an abnormal audio signal, indicating that the air tightness of the electronic device 100 is good.

[0058] Optionally, in this embodiment, the controller determines the air tightness detection result according to the low-frequency region in the detected audio signal. Since if the detected audio signal is an abnormal audio signal, the distortion in the low-frequency region of the detected audio signal is particularly serious, and the difference between the low-frequency region of the detected audio signal and the low-frequency region of the reference audio signal is obvious, the air tightness detection result can be obtained by comparing the difference between the low-frequency region of the detected audio signal and the low-frequency region of the reference audio signal, so that the air tightness detection result is more accurate.

[0059] The technical scheme provided by the embodiment of the present application is characterized in that the air hole of the electronic device 100 is blocked, the electronic device 100 is heated to increase the temperature inside the electronic device 100, the pressure of the rear sound cavity 22 of the loudspeaker 2 changes to reflect the difference in audio signal output, and then the air tightness of the whole electronic device 100 is determined. The detection method is feasible in principle, controllable in cost, simple to operate, and can be applied to production lines and daily life.

[0060] The method only needs to add a heating platform 200 on the production line, does not need to add other equipment, can realize air tightness detection by using the existing audio detection equipment of the production line, is rapid and reliable in detection, and is controllable in cost. The method is simple and rapid in detecting the air tightness of the whole machine, and consumers can also monitor the air tightness of the electronic device 100 at home by using the detection algorithm of the electronic device 100, so that the risk of water damage to the electronic device 100 can be avoided.

[0061] Please refer to Figure 8 , Figure 8 The air tightness detection method of the electronic device provided by the embodiment of the present application is based on the electronic device 100 as described above, and is used to detect the air tightness of the electronic device 100. In the embodiment, the method includes but is not limited to the following steps:

[0062] Step S510: heating the electronic device until the temperature of the electronic device reaches a preset temperature threshold.

[0063] Specifically, the heating platform 200 quickly heats the internal temperature of the electronic device 100 to a preset temperature threshold. The heating platform 200 can quickly heat the electronic device 100, so that the internal temperature of the electronic device 100 quickly rises to the preset temperature threshold. The preset temperature threshold can be 50℃, etc.

[0064] Step S520: controlling the electronic device to play a preset audio.

[0065] Specifically, the preset audio is pre-stored in the electronic device 100, and the controller controls the loudspeaker 2 to play the preset audio.

[0066] Step S530: collecting a detection audio signal of the electronic device in the case that the air hole of the electronic device is blocked.

[0067] Specifically, in the process of playing the preset audio by the loudspeaker 2, the air hole of the electronic device 100 can be blocked by clay or the like. The controller controls the audio receiver 3 to collect the detection audio signal of the electronic device 100, and the audio receiver 3 inputs the collected detection audio signal to the controller.

[0068] Step S540: determining an air tightness detection result according to the detection audio signal.

[0069] Specifically, the controller can be an audio test device on the production line or a mainboard of the electronic device 100. On the production line, the audio signal collected by the audio receiver 3 can be converted into an electrical signal and input into the audio test device, and the air tightness detection result can be obtained by analyzing the difference between the signals and fed back to the production line operator through the audio test device. In daily life, the audio signal collected by the audio receiver 3 can be converted into an electrical signal and input into the mainboard of the electronic device 100, and the air tightness detection result can be obtained by analyzing the difference between the signals through a specific algorithm and fed back to the consumer through the screen of the electronic device 100.

[0070] The controller obtains the air tightness detection result by comparing the difference between the detection audio signal and the reference audio signal. In this embodiment, step S540 includes: if the similarity between the detection audio signal and the reference audio signal is greater than a first similarity threshold, determining that the air tightness detection result is air tightness failure; and if the similarity between the detection audio signal and the reference audio signal is less than a second similarity threshold, determining that the air tightness detection result is air tightness good.

[0071] Specifically, the first similarity threshold is not less than the second similarity threshold, and the reference audio signal is an audio signal collected when the air hole is not blocked and a preset audio is played. The similarity between the detection audio signal and the reference audio signal is obtained by comparing the audio curve of the detection audio signal with the audio curve of the reference audio signal. If the similarity between the detection audio signal and the reference audio signal is high, it means that the detection audio signal is a normal audio signal, indicating that the air tightness of the electronic device 100 is poor; if the similarity between the detection audio signal and the reference audio signal is low, it means that the detection audio signal is an abnormal audio signal, indicating that the air tightness of the electronic device 100 is good.

[0072] Optionally, in this embodiment, step S540 includes: determining the air tightness detection result according to the low frequency region in the detection audio signal. The controller determines the air tightness detection result according to the low frequency region in the detection audio signal. Since the distortion of the low frequency region in the detection audio signal is particularly serious if the detection audio signal is an abnormal audio signal, the difference between the low frequency region in the detection audio signal and the low frequency region in the reference audio signal will be obvious, so the air tightness detection result is obtained by comparing the difference between the low frequency region in the detection audio signal and the low frequency region in the reference audio signal, so that the air tightness detection result is more accurate.

[0073] The whole machine air tightness of the electronic device 100 is detected by the method, which has the characteristics of simplicity and rapidness, and the air tightness equipment is not needed on the production line, only a simple heating platform 200 is needed, and the air tightness is detected by the existing audio detection equipment and the vibration condition in the low-frequency area.
