Referring to fig. 1, a schematic diagram of an application system of an audio jack testing tool 100 according to an embodiment of the present invention is shown. The application system includes an electronic device 200 and an audio jack testing tool 100.
The electronic device 200 is a device having an audio playing function and an audio recording function, and may be, for example, a notebook computer, a desktop computer, a tablet computer, a smart phone, a smart watch, and the like. The electronic device 200 is provided with an audio jack 201, and the audio jack 201 is a two-in-one jack for an earphone and a microphone. Therefore, when the audio jack 201 of the electronic device 200 is plugged into an earphone, a user can listen to the sound played by the player built in the electronic device 200 through the earphone with a microphone, and can record the sound. For example, when a voice conference is performed with a notebook computer (electronic device 200), the user can talk with another person by inserting an earphone with a microphone into the audio jack 201 of the notebook computer and matching with corresponding voice software.
Specifically, the audio jack 201 includes a sound channel contact piece, a ground contact piece, and a microphone contact piece (not shown), when a plug of an earphone with a microphone is inserted into the audio jack 201, a sound channel region on the earphone plug is communicated with the sound channel contact piece, a ground region on the earphone plug is communicated with the ground contact piece, and a microphone region on the earphone plug is communicated with the microphone contact piece, so that an audio signal output by the electronic device 200 is transmitted to a speaker of the earphone through the sound channel contact piece and the sound channel region, and the audio signal is converted into sound by the speaker and transmitted to the ear of the user. When the user records, the microphone on the earphone converts the voice of the user into a recording signal, and the recording signal is transmitted to the electronic equipment 200 through the microphone area and the microphone contact piece, namely, the recording audio is obtained.
It can be understood that, as shown in fig. 2, the audio plug of the earphone under the national standard has the audio zones-microphone zone-ground zone arranged in sequence, and the contacts in the corresponding audio jack have the audio contacts-microphone contact-ground contact arranged in sequence. All the areas in the audio plug of the earphone under American standard are sequentially arranged according to a sound channel area, a grounding area and a microphone area, and all the contacts in the corresponding audio jack are sequentially arranged according to a sound channel contact, a grounding contact and a microphone contact. It is understood that the audio jack of the electronic device may conform to national standards and may also conform to American standards. However, in the conventional detection method, two audio jack test tools with different structures are used to detect audio jacks respectively meeting the national standard and the American standard, and the problem of false alarm in the test and the like is often caused by using a wrong tool.
Based on the above situation, in order to increase the convenience of factory detection of the audio jack 201, the invention provides an audio jack testing tool 100, which can be compatible with audio jacks respectively meeting the national standard and the American standard so as to perform factory detection. The audio jack test tool 100 can be matched with the audio jack 201 of the electronic device 200 through switching states, and therefore playing transmission and recording transmission of audio signals can be achieved. The testing tool 100 can transmit the audio signal output by the sound channel contact of the audio jack 201 back to the microphone contact of the audio jack 201 to record the audio, so that whether the audio jack is normal can be determined according to the recorded audio, for example, if the recorded audio is normal, it indicates that the sound channel area of the audio jack can normally output the audio signal, and the microphone area can normally input the audio signal, so that the audio jack is qualified.
Referring to fig. 3, the audio jack testing tool 300 includes an audio plug 30, where the audio plug 30 includes a first sound channel region 31, a first contact region 32, and a second contact region 33, and an insulating layer 34 is disposed between any two adjacent regions of the first sound channel region 31, the first contact region 32, and the second contact region 33.

When the audio jack testing tool 300 is in the first state to test the three-pin audio jack conforming to the national standard, the audio signal input from the first channel region 31 is filtered by the first capacitor 51 and then transmitted to the first touch region 32, so that the first capacitor 51 can eliminate the dc signal mixed in the audio signal, thereby reducing the interference in the audio signal and being beneficial to improving the accuracy of audio jack detection. Similarly, when the audio jack testing tool 300 is in the second state to test the three-pin audio jack meeting the standards of the U.S. standards, the audio signal input from the first channel region 31 is filtered by the second capacitor 52 and then transmitted to the second touch region 33, so that the second capacitor 52 can eliminate the dc signal mixed in the audio signal, thereby reducing the interference in the audio signal and being beneficial to improving the accuracy of audio jack detection.

The switch 40 is further configured to switch between a third state and a fourth state, wherein the third state is an electrical connection between the second channel region 35 and the first contact region 32, and the fourth state is an electrical connection between the second channel region 35 and the second contact region 33.

Through the state switching of the switch 40, the audio jack testing tool 300 can detect the four-pin audio jack conforming to the national standard specification and also can detect the four-pin audio jack conforming to the American standard specification. Specifically, the audio plug 30 of the test tool is inserted into an audio jack of the electronic device. When the four-pin audio jack meets the national standard, the switch 40 is switched to the third state to electrically connect the loop between the second channel region 35 and the first touch region 32, and the audio signal output by the electronic device is transmitted to the electronic device in the loop formed by the second channel region 35, the third capacitor 53 and the first touch region 32 to determine whether the audio jack is normal according to the audio signal, at this time, the first touch region 32 is a microphone region, and the second touch region 33 is a ground region to adapt to the detection of the four-pin audio jack under the national standard.
