[0023] Example

[0024] In one embodiment of this utility model, reference is made to Figure 1 As shown, this utility model discloses a portable acoustic analyzer, comprising:

[0025] The housing has external dimensions of 324*223*86mm. It comprises a screen cover 1, a middle frame 2, and a bottom plate 3, all of which can be detachably assembled. The middle frame 2 has a U-shaped structure. The screen cover 1, middle frame 2, and bottom plate 3 are all made of metal such as aluminum, which is obtained through sandblasting and anodizing, effectively shielding the influence of external electromagnetic fields on the accuracy and sensitivity of the acoustic information acquisition circuit. The screen cover 1 has a hollowed-out design; specifically, the hollowed-out 16 is a square through-hole.

[0026] The touch screen all-in-one machine 7 includes a main control module and a touch display module 9, a microphone 71, a speaker 72, a USB interface, a network port, and a processing module, all of which are electrically connected to the main control module. The processing module is used to perform complex acoustic calculations and includes a CPU and a motherboard. The touch screen all-in-one machine 7 is located inside the housing, and the display module 9 is positioned directly opposite the cutout 16 of the screen cover plate 1 and is pressed by the screen cover plate 1.

The wireless communication module includes a Bluetooth module, a Wi-Fi module, etc., for enabling network uploading and sharing of the analyzer.

[0029] In one embodiment of this utility model, reference is made to Figure 1 As shown, the screen cover 1, the middle frame 2, and the bottom plate 3 are all made of metal, such as aluminum. The all-metal shell effectively shields the external electromagnetic field from affecting the accuracy and sensitivity of the acoustic information acquisition circuit. The four corners of the screen cover 1 are rounded chamfers. The four corners of the bottom plate 3 are also rounded chamfers, which not only improves the feel but also reduces stress concentration. Compared with right angles, rounded chamfers can reduce stress concentration caused by sudden angle changes, thereby reducing the risk of fatigue and breakage of the shell material.

[0030] In one embodiment of this utility model, reference is made to Figure 1 As shown, the screen cover 1 is provided with a speaker opening 13 and a microphone opening 12. After removing the screen cover 1, the speaker 72 and microphone 71 can be cleaned.

The brackets 26 can be detachably connected to the inner walls of the four inner corners of the middle frame 2. The brackets 26 support the touch screen all-in-one machine 7. The four corners of the touch screen all-in-one machine 7 only need to be placed on the four brackets 26 and pressed by the brackets 26 and the screen cover plate 1 to achieve fixation.

[0032] In one embodiment of this utility model, reference is made to Figure 1 As shown, the four inner corners of the middle frame 2 are provided with a first mounting hole 25 and a second mounting hole 27. The first mounting hole 25 and the second mounting hole 27 are located at the upper and lower parts of the middle frame 2, respectively. The screen cover plate 1 is provided with a screw hole 15 corresponding to the first mounting hole 25. The bottom plate 3 is provided with a third mounting hole 32 corresponding to the second mounting hole 27. The screen cover plate 1 and the middle frame 2, and the middle frame 2 and the bottom plate 3 can be quickly fixed by screws.

[0033] In one embodiment of this utility model, reference is made to Figure 1 As shown, the bottom of the screen cover plate 1 is provided with a first annular limiting rib 14, which surrounds the edge of the screen cover plate 1. The upper part of the bottom plate 3 is provided with a second annular limiting rib 31, which surrounds the edge of the bottom plate 3. The upper part of the middle frame 2 is provided with an annular limiting groove 10, which matches the first annular limiting rib 14. The annular limiting groove 10 is formed by the side of the bracket 26 and the side wall of the middle frame 2. The first annular limiting rib 14 is inserted into the annular limiting groove 10 to limit the screen cover plate 1 in the horizontal direction. The second annular limiting rib 31 is located inside the middle frame 2 and abuts against the inner wall of the middle frame 2 to limit the screen cover plate 1 in the horizontal direction.

[0034] In one embodiment of this utility model, reference is made to Figure 2 As shown, the middle frame 2 is provided with a first interface 22, a second interface 29, a third interface 210, a heat dissipation hole 24, and a power opening 21.
