If the air tightness of the electronic device 100 is good, if the ventilation holes are blocked by plasticine or the like, a completely closed space is formed inside the housing 1 of the electronic device 100; if the air tightness of the electronic apparatus 100 is poor, that is, the ventilation holes are blocked by using plasticine or the like, the inside of the case 1 is still in communication with the external space, and a completely closed space cannot be formed inside the case 1.

The audio receiver 3 is disposed in the inner space of the housing 1, the audio receiver 3 can use the audio signal of the speaker 2, and the audio receiver 3 can convert the audio signal into an electrical signal. The audio receiver 3 may be an original component of the electronic device 100, for example, a microphone is typically disposed on the electronic device 100, and the audio receiver 3 may be a microphone; the audio receiver 3 may also be an additional component of the electronic device 100.
Optionally, referring to fig. 2, in the present embodiment, the audio receiver 3 is disposed on the outer surface of the shell of the loudspeaker 2, so that the audio receiver 3 can collect the audio signal of the loudspeaker 2 more accurately.

The controller can determine the air tightness detection result according to the detection audio signal collected by the audio receiver 3, the controller can be an audio test device on a production line or a main board on the electronic device 100, if the controller is the audio test device on the production line, the controller is not part of the electronic device 100, i.e. the electronic device 100 does not include the controller; if the controller is a motherboard on the electronic device 100, the controller is part of the electronic device 100, i.e., the electronic device 100 includes the controller.
On the production line, can select the audio test equipment on the production line as the controller, can convert the detection audio signal that audio receiver 3 gathered into the electrical signal and input to audio test equipment, audio test equipment obtains the gas tightness testing result through the difference of analysis signal to feed back to the production line operator through audio test equipment.
In daily life, a main board on the electronic device 100 can be selected as a controller, the detected audio signals collected by the audio receiver 3 can be converted into electrical signals and input to the main board, and the main board analyzes the signal differences through a specific algorithm. Optionally, referring to fig. 1, in the present embodiment, the electronic device 100 further includes a screen (not shown in the figure) for displaying the air tightness detection result, so that the air tightness detection result can be fed back to the consumer by using the screen on the electronic device 100.
In the design and manufacturing process of the electronic device 100 with waterproof performance, it is to ensure that all holes and bonding positions on the electronic device 100 are sealed, and an airtight space is formed between the interior and the outside of the electronic device 100, but in order to ensure that the internal pressure and the external pressure of the electronic device 100 are the same, referring to fig. 4, a waterproof and breathable film 4 is adhered to a rear position of a battery cover of the electronic device 100, and the waterproof and breathable film 4 is communicated, so that under a normal condition that the whole electronic device 100 has good air tightness, no additional action is performed, the front sound cavity 24, the rear sound cavity 22 and the atmospheric pressure of the loudspeaker 2 are the same, at this time, the loudspeaker 2 is controlled to play preset audio, and a normal audio signal collected by the audio receiver 3 is fed back to the controller, and the normal audio signal is used as a reference audio signal and stored in the controller.
In order to simply and quickly detect the air tightness of the whole electronic device 100, the ventilation holes communicated with the outside of the waterproof and breathable film 4 are blocked by using plasticine or the like, and 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 description will be given below taking the preset temperature threshold as 50 ℃ as an example). Alternatively, referring to fig. 1, in the present embodiment, the electronic device 100 is configured with a heating platform 200, the heating platform 200 is used to heat the electronic device 100, and the electronic device 100 can be quickly heated to 50 ℃ by using the heating platform 200.
When the electronic device 100 is heated to 50 c, the internal temperature of the electronic device 100 is increased, resulting in an increase in the internal air pressure of the electronic device 100, and the internal space of the electronic device 100 communicates with the rear sound chamber 22 of the horn 2, resulting in an increase in the pressure in the rear sound chamber 22 of the horn 2. Referring to fig. 5, fig. 5 shows that in the fixed space, the internal pressure of the electronic device 100 changes with temperature, when the room temperature is 20 ℃, the internal temperature of the electronic device 100 reaches 50 ℃, and the pressure change is 1.0×10 5 Pa is 1.102 x 10 5 Pa. Since the sound generating device 23 is disposed inside the sound cavity, when the pressure in the rear sound cavity 22 increases, referring to fig. 6, the damping coefficient in air changes with the pressure, and the greater the pressure, the greater the air damping coefficient.
Referring to fig. 7, the enhancement of air damping affects the vibration of the cone of the sound generating device 23, and blocks the motion stroke of the cone, thereby causing sound distortion, especially affecting the 5Hz low-frequency vibration of the sound generating device 23, and the distortion of the low-frequency region is particularly serious, at this time, the speaker 2 is controlled to play a preset audio, the audio receiver 3 collects the audio signal of the speaker 2 to obtain an abnormal audio signal, which is different from the audio signal (i.e. the reference audio signal) of the non-blocking waterproof and breathable film 4, and the audio receiver 3 can feed the collected abnormal audio signal back to the controller. If the air tightness of the electronic device 100 is poor, when the ventilation holes communicated with the outside by the waterproof and breathable film 4 are blocked by using plasticine and the like, the air pressure in the electronic device 100 cannot be changed along with the temperature rise, and the audio receiver 3 still receives a normal audio signal which is the same as the audio signal of the waterproof and breathable film 4 which is not blocked.
The controller can determine the air tightness detection result according to the difference between the detected audio signal and the reference audio signal, optionally, 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 smaller than the second similarity threshold, the controller determines that the air tightness detection result is good air tightness.
Specifically, the first similarity threshold is not smaller than the second similarity threshold, and the reference audio signal is an audio signal acquired under the condition that the air holes are not blocked and the preset audio is played. And comparing the audio curve of the detection audio signal with the audio curve of the reference audio signal to obtain the similarity between the detection audio signal and the reference audio signal. If the similarity between the detected audio signal and the reference audio signal is higher, the detected audio signal is a normal audio signal, which indicates that the electronic device 100 has poor air tightness; if the similarity between the detected audio signal and the reference audio signal is low, the detected audio signal is an abnormal audio signal, which indicates that the air tightness of the electronic device 100 is good.
Optionally, in this embodiment, the controller determines the air tightness detection result according to the low frequency region in the detected audio signal, and if the detected audio signal is an abnormal audio signal, since the distortion of the low frequency region in the detected audio signal is particularly serious, the difference between the low frequency region in the detected audio signal and the low frequency region in the reference audio signal is obvious, so that the air tightness detection result is obtained by comparing the difference between the low frequency region in the detected audio signal and the low frequency region in the reference audio signal, and thus the air tightness detection result is more accurate.
According to the technical scheme provided by the embodiment of the invention, the ventilation holes of the electronic equipment 100 are blocked, the electronic equipment 100 is heated to enable the internal temperature of the electronic equipment 100 to rise, the pressure change of the rear sound cavity 22 of the loudspeaker 2 is caused to reflect the difference of audio signal output, and then the air tightness of the whole electronic equipment 100 is judged.
According to the method, only one heating platform 200 is needed to be added on the production line, other equipment is not needed to be added, the existing audio detection equipment of the production line can be utilized to realize air tightness detection, and the detection is rapid and reliable, and the cost is controllable. The method for detecting the air tightness of the whole machine is simple and rapid to operate, and consumers can also monitor the air tightness of the electronic equipment 100 by using the detection algorithm carried by the electronic equipment 100 at home, so that the risk of water inlet damage of the electronic equipment 100 can be avoided.

Specifically, the heating platform 200 may rapidly heat the electronic device 100 to a preset temperature threshold by rapidly heating the electronic device 100 by the heating platform 200, so that the internal temperature of the electronic device 100 may rapidly increase to the preset temperature threshold, where the preset temperature threshold may be 50 ℃.
Step S520: and controlling the electronic equipment to play the preset audio.
Specifically, the preset audio is pre-stored in the electronic device 100, and the controller controls the speaker 2 to play the preset audio.
Step S530: under the condition of blocking the ventilation holes of the electronic equipment, the detection audio signals of the electronic equipment are collected.
Specifically, in the process of playing the preset audio by the speaker 2, the ventilation holes of the electronic device 100 may be blocked by plasticine 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.
Step S540: and determining the air tightness detection result according to the detection audio signal.
In particular, the controller may be an audio test device on a production line or a motherboard of the electronic device 100. On the production line, the audio signals collected by the audio receiver 3 can be converted into electrical signals to be input into audio test equipment, the air tightness detection result is obtained by analyzing the difference of the signals, and the electrical signals are fed back to an operator of the production line through the audio test equipment.

Specifically, the first similarity threshold is not smaller than the second similarity threshold, and the reference audio signal is an audio signal acquired under the condition that the air holes are not blocked and the preset audio is played. And comparing the audio curve of the detection audio signal with the audio curve of the reference audio signal to obtain the similarity between the detection audio signal and the reference audio signal. If the similarity between the detected audio signal and the reference audio signal is higher, the detected audio signal is a normal audio signal, which indicates that the electronic device 100 has poor air tightness; if the similarity between the detected audio signal and the reference audio signal is low, the detected audio signal is an abnormal audio signal, which indicates that the air tightness of the electronic device 100 is good.
