[0058] Combination Figure 1 As shown, the electronic device includes: a housing 1, a sealing structure 4, a functional device 2 and a waterproof and breathable component 3.

[0059] Among them, the sealing structure 4 is located on the inner side of the shell 1, and forms a sealed chamber 12 with the inner wall of the shell 1; the functional device 2 is located in the sealed chamber 12; the shell 1 is provided with a first air vent 11, and the first air vent 11 connects the sealed chamber 12 and the external air; the waterproof and breathable component 3 covers the first air vent 11.

[0060] In the electronic device of this embodiment, the sealing structure 4 is located on the inner side of the shell 1, and forms a sealed chamber 12 with the inner wall of the shell 1. The functional device 2 is located in the sealed chamber 12. The sealed chamber 12 is connected to the external air via the first air hole 11 on the shell 1, and a waterproof and breathable component 3 is arranged on the first air hole 11 to prevent water from entering while ensuring that external air can flow into the sealed chamber 12, so that the functional device 2 can be used to detect the air in the sealed chamber 12, and the functional device 2 realizes the detection of the external air.

[0061] Combination Figure 1 As shown, in some embodiments, the sealing structure 4 includes a first sealing member 41 and a second sealing member 42 , the first sealing member 41 is spaced apart from the inner wall of the housing 1 , and the second sealing member 42 is located between the first sealing member 41 and the housing 1 .

[0062] The sealing structure 4 of this embodiment includes a first sealing member 41 and a second sealing member 42, wherein the first sealing member 41 is arranged to be spaced apart from the inner wall of the shell 1, and the second sealing member 42 is connected between the first sealing member 41 and the shell 1, and the second sealing member 42 and the first sealing member 41 form a concave structure with an opening on one side, and the concave structure can be easily connected to the inner wall of the shell 1, which is conducive to simplifying the assembly of the sealing chamber 12 and improving the practicality and assembly convenience of this embodiment.

[0063] Combination Figure 1 As shown, in some embodiments, the first sealing member 41 is a circuit board, and the functional device 2 is electrically connected to the surface of the first sealing member 41 .

[0064] The first sealing member 41 of this embodiment is a circuit board, and the functional device 2 is electrically connected to the surface of the first sealing member 41, which is conducive to simplifying the difficulty of assembling the functional device 2. The functional device 2 can be directly welded to the surface of the first sealing member 41, and there is no need to design independent wiring for the functional device 2. In addition, the first sealing member 41 can also be used as a circuit board inside the electronic device, and the second structural sealing member is connected between the circuit board where the functional device 2 is located and the inner wall of the housing 1, and the local space between the circuit board and the inner wall of the housing 1 is enclosed to form a sealed chamber 12, and the functional device 2 is enclosed inside to achieve the sealing of the functional device 2.

[0065] In some possible implementations, the functional device 2 is one or more of the following: an air pressure sensor, a temperature sensor, and a sound pickup sensor.

[0066] Among them, air pressure sensors are divided into variable capacitance air pressure sensors and variable resistance air pressure sensors. Changes in air pressure will cause changes in the resistance or capacitance measurement values. Air pressure sensors can be used in scenarios such as air pressure measurement, altitude measurement, navigation assistance, and indoor positioning.

[0067] Based on the principle that different altitudes have different air pressures, air pressure sensors can be used to measure changes in altitude. For example, a mobile phone equipped with an air pressure sensor can be used to measure how many floors a user has climbed, or for indoor positioning.

[0068] For example, the sensing element of the air pressure sensor is a film that is sensitive to air pressure and a pin, and a flexible resistor is connected to it in the circuit. When the pressure of the measured gas decreases or increases, the film deforms and drives the pin, and the resistance value of the resistor will change. The resistance value of the resistor changes. The 0-5V signal voltage is obtained from the sensing element, received by the data acquisition device after A / D conversion, and then the data acquisition device transmits the result to the computer in an appropriate form.

[0069] Among them, the sound pickup sensor realizes the conversion of sound and electricity. For example, the electret microphone used in the mobile phone is composed of a piece of electret film coated with metal on one side and a metal electrode (the back is called the back electrode) with several small holes on it. The electret surface is opposite to the back electrode, and there is a very small air gap in the middle, forming a flat plate capacitor with the air gap and the electret as insulating medium, and the back electrode and the metal layer on the electret as two electrodes. There is an output electrode between the two poles of the capacitor. Because free charges are distributed on the electret film. When the sound waves in the external air enter the sealed chamber 12 through the first air permeable hole 11 and the waterproof and breathable component 3, they act on the electret microphone, causing the electret film to vibrate and produce displacement; the distance between the two plates of the capacitor is changed, thereby causing the capacity of the capacitor to change. Since the number of charges on the electret is always kept constant, when the capacity of the capacitor changes, it will inevitably cause the voltage at both ends of the capacitor to change, thereby outputting an electrical signal to achieve the conversion of sound and electricity.

[0070] Combination Figure 2 As shown, in some embodiments, one side of the second sealing member 42 close to the inner wall of the shell 1 extends in a direction parallel to the inner wall of the shell 1 to form a connecting portion 421, and a second air hole 422 is provided on the connecting portion 421; the orthographic projection of the second air hole 422 in a plane parallel to the inner wall of the shell 1 and the orthographic projection of the first air hole 11 in a plane parallel to the inner wall of the shell 1 at least partially overlap.

[0071] Taking into account that the sealing structure component needs to be connected to the inner wall of the shell 1 to achieve an overall structural fixed assembly scenario, a connecting portion 421 is arranged on the second sealing member 42. The connecting portion 421 is parallel to the inner wall of the shell 1 and can be connected to the inner wall of the shell 1 with a larger contact area. This connection method includes but is not limited to adhesive connection, welding connection, fastener connection, etc., while increasing the contact area between the second sealing member 42 and the inner wall of the shell 1, which is also beneficial to increase the sealing width between the two and improve the sealing effect.

[0072] In order to prevent the connection part 421 from affecting the flow of external air into the sealed chamber 12, a second air hole 422 is arranged on the connection part 421, and the orthographic projection of the second air hole 422 and the first air hole 11 on a plane parallel to the inner wall of the shell 1 at least partially overlaps, that is, the first air hole 11 and the second air hole 422 are connected.

[0073] Combination Figure 2 As shown, in some embodiments, the connecting portion 421 is connected to the shell 1, the waterproof breathable component 3 is located between the connecting portion 421 and the shell 1, and the orthographic projection of the waterproof breathable component 3 in a plane parallel to the inner wall of the shell 1, the orthographic projection of the second air hole 422 in a plane parallel to the inner wall of the shell 1, and the orthographic projection of the first air hole 11 in a plane parallel to the inner wall of the shell 1 at least partially overlap.

[0074] The waterproof and breathable component 3 of this embodiment is located between the connecting portion 421 and the shell 1, the upper end surface of the waterproof and breathable component 3 contacts and is supported on the inner wall of the shell 1, and the lower end surface of the waterproof and breathable component 3 contacts and is supported on the connecting portion 421. The shell 1 and the connecting portion 421 can support the waterproof and breathable component 3 from the upper and lower sides respectively, thereby preventing the waterproof and breathable component 3 from being squeezed, deformed, or falling off due to external force.

[0082] The waterproof breathable component 3 of this embodiment has a buffer layer 33 arranged between the waterproof breathable membrane 31 and the connecting portion 421. The buffer layer 33 can play a buffering and shock-absorbing function when the external air pressure is large and the waterproof breathable membrane 31 is subjected to inward pressure, thereby improving the reliability of the waterproof breathable membrane 31 and reducing noise.
