[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] like Figure 1 and Figure 2 As shown, the electronic product sound detection system of the embodiment of the utility model includes an electronic product 1, a probe card 2, a sound generator 3 and a switch 6.

[0030] The electronic product 1 includes a mainboard 11 and a sound input module 12 electrically connected to the mainboard 11. For example, the electronic product 1 may be a mobile phone, and the mainboard 11 is the mainboard 11 of the mobile phone. In some other embodiments, the electronic product 1 may also be an electronic product 1 such as a tablet computer, a smart watch, or a laptop computer.

[0031] The sound input module 12 can be a microphone. The sound input module 12 can be fixed on the mainboard 11 by welding or bonding, and the sound input module 12 is electrically connected to the circuit inside the mainboard 11. The mainboard 11 can convert the sound wave information received by the sound input module 12 into an electrical signal, which can then be transmitted through the circuit of the mainboard 11.

[0032] The probe card 2 includes a plurality of probes 21 for electrically contacting the test points on the main board 11. For example, Figure 1 As shown, the probe plate 2 can be flat and can be arranged horizontally. The probe plate 2 is made of a transparent material. Specifically, the material of the probe plate 2 can be a transparent acrylic plate. A plurality of probes 21 can be mounted and fixed on the probe plate 2, and the material of the probes 21 can be copper. When in use, the probe plate 2 can be pressed onto the above-mentioned main board 11. At this time, the plurality of probes 21 on the probe plate 2 can be respectively abutted against the plurality of test points on the main board 11, thereby meeting the use needs of the power consumption current test.

[0033] The sound generator 3 is disposed on the probe card 2 , the switch 6 is electrically connected to the sound generator 3 and is used to control the opening and closing of the sound generator 3 , and the sound generator 3 is arranged opposite to the sound input module 12 and is used to send sound waves to the sound input module 12 when turned on.

[0034] For example, the sound generator 3 may be a buzzer, and in some other embodiments, may be a speaker, a player, or other devices capable of autonomous sound generation. The sound generator 3 may be fixed on the probe card 2 and may face the sound input module 12. For example, a card slot may be provided on the probe card 2, and the sound generator 3 may be snap-fitted and assembled in the corresponding card slot.

[0035] The switch 6 can be manual, and the switch 6 can be connected in series with the sound generator 3. When the switch 6 is closed, the current of the sound generator 3 is connected, and at this time, the sound generator 3 can make a sound by itself, so that the sound wave can be sent to the sound input module 12. When the switch 6 is opened, the current of the sound generator 3 is cut off, and at this time, the sound generator 3 stops generating sound waves, that is, the detection is finished.

[0036] The electronic product sound detection system of the embodiment of the utility model can generate sound waves by using the sound generator 3 by manually closing the switch 6 when performing sound wave detection, thereby meeting the use needs of sending sound waves to the sound input module 12. It avoids the problem of high labor intensity of the detection personnel in the prior art that sound waves need to be generated by human power such as hitting the jig and shouting, alleviates the situation that the personnel are easily fatigued, and improves the convenience of the detection operation. Secondly, compared with the situation of artificial sounding, it also realizes the uniformity and standardization of sound wave emission, which is conducive to reducing the detection differences caused by different sound waves.

[0037] In some embodiments, the electronic product sound detection system includes a sound tube 4 , which is disposed on the probe card 2 , a sound generator 3 is disposed at the inlet of the sound tube 4 , and a sound input module 12 is disposed at the outlet of the sound tube 4 .

[0039] The sound generator 3 can be fixed on the probe plate 2, and the sound generator 3 can be arranged opposite to the inlet of the sound tube 4. The sound input module 12 can be arranged opposite to the outlet of the sound tube 4. When in use, the sound waves generated by the sound generator 3 can be diffused along the sound tube 4, avoiding the situation where the sound waves are seriously diffused due to the long distance between the sound generator 3 and the sound input module 12, and ensuring the intensity of the sound waves received by the sound input module 12.

The top inlet of the sound tube 4 can be connected to the bottom of the assembly groove. During assembly, the sound generator 3 can be directly placed in the assembly groove. At this time, the transmitting end of the sound generator 3 will be arranged opposite to the inlet of the sound tube 4. Thereby improving the convenience of assembly and facilitating the inspection and replacement of the sound generator 3.

[0041] In some embodiments, the acoustic tube 4 is detachably connected to the probe board 2. For example, the acoustic tube 4 can be fixed to the bottom side of the probe board 2 by threaded assembly. When different electronic products 1 are tested, the lowering displacement of the probe board 2 will change due to the thickness difference of the electronic products 1 themselves. At this time, the acoustic tube 4 with matching length can be replaced, thereby meeting the use needs of testing different electronic products 1 and enhancing the versatility of the detection system.

[0042] In some embodiments, the electronic product 1 includes a sound output module 13, which is disposed on the mainboard 11 and electrically connected to the mainboard 11, and is used to play back the sound waves received by the sound input module 12.

[0043] During the process of sound wave detection, the sound waves generated by the sound generator 3 can be transmitted to the sound input module 12 and received by the sound input module 12, and then the converted electrical signals can be transmitted to the sound output module 13 via the lines in the mainboard 11. The sound can be played back by the sound output module 13, thereby meeting the use needs of sound wave collection and release detection.

[0044] In some embodiments, the electronic product sound detection system includes a detection device, the sound generator 3 includes a positive wire 31 and a negative wire 32, the switch 6 is arranged on one of the positive wire 31 and the negative wire 32, and the positive wire 31 is electrically connected to the positive pole of the detection device, and the negative wire 32 is electrically connected to the negative pole of the detection device.

[0045] For example, Figure 2 As shown, the detection device as a whole can be a desktop device, and the detection device can include some drivers, clamps and other components. When in use, the driver can drive the probe board 2 to move back and forth in the up and down directions, thereby satisfying the need to stop the probe 21 on the probe board 2 on the motherboard 11 of the electronic product 1.

[0046] The switch 6 can be installed on the positive wire 31. The detection device has an external power supply. The positive wire 31 and the negative wire 32 of the generator can be directly connected to the power supply of the detection device, thereby meeting the need for nearby power supply and improving the convenience of connection.

[0047] In some embodiments, the detection device includes a limiting fixture 5, the limiting fixture 5 is provided with a limiting groove 51 for placing the electronic product 1, and the probe card 2 is arranged on one side of the notch of the limiting groove 51. Figure 1As shown, the limiting fixture 5 can be a plate-shaped structure as a whole, and the limiting fixture 5 can be fixed on the corresponding platform of the detection device, and the limiting groove 51 is provided on the top side of the limiting fixture 5, and the notch of the limiting groove 51 faces upward, and the probe plate 2 can be located above the limiting fixture 5. When in use, the electronic product 1 can be directly placed in the limiting groove 51, and then the probe plate 2 can be driven downward and contact with the corresponding test point of the electronic product 1.
