[0089] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0090] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0091] Example 1: Refer to Figure 1-3 A testing apparatus for Bluetooth devices includes: a test box 1, a mesh conveyor belt 2, a test seat 3, a toothed bar 5, a movable disk 6, and a testing system, etc.

[0092] The test chamber 1 has an opening that passes through it; a mesh conveyor belt 2 passes through the opening to transport the Bluetooth device to be tested; multiple test seats 3 are evenly distributed on the mesh conveyor belt 2; a linear drive assembly 4 is installed in the test chamber 1; two racks 5 are connected to the linear drive assembly 4; a movable disk 6 is connected to the lower ends of the two racks 5 and moves with the racks 5; the test system is installed on the movable disk 6.

[0093] During testing, the mesh conveyor belt 2 is used to move the test stand 3. The Bluetooth device under test is placed in the test slot on the test stand 3 to restrict the position of the Bluetooth device. After moving into the test box 1, the linear drive component 4 drives the rack 5 to descend, thereby making the movable plate 6 and the test system contact the test stand 3, thus testing the Bluetooth device on the test stand 3.

[0094] The mounting cavity is arranged in an "m" shape, with the linear drive assembly 4 located in the middle vertical cavity; two gears 7 are installed in the middle vertical cavity and mesh with the rack 5; two rollers 8 are rotatably arranged in the mounting cavity and are respectively connected to the two gears 7; two pull ropes 9 are respectively wound around the two rollers 8, and when the two rollers 8 rotate, the pull ropes 9 are tightened or loosened simultaneously; two protective doors 10 are respectively slidably installed in the vertical cavities on both sides of the mounting cavity, and their upper ends are respectively connected to the two pull ropes 9.

[0095] The protective door 10 is configured such that when the toothed rod 5 descends, the roller 8 loosens the pull rope 9, and when the roller 8 rotates, the pull rope 9 is gradually disengaged from the roller 8, thereby loosening the pull rope 9 so that the two protective doors 10 descend; and the protective door 10 is also configured such that when the toothed rod 5 rises, the roller 8 tightens the pull rope 9 so that the two protective doors 10 rise.

[0096] Before measurement, the movable plate 6 and the testing system rise, and the protective door 10 also rises. This allows the mesh conveyor belt 2 to move the test seat 3, allowing the test seat 3 and the Bluetooth device to enter the test chamber 1. Then, the movable plate 6 and the testing system descend, and the protective door 10 also descends to protect the test. The test is then performed after the movable plate 6 and the test seat 3 come into contact. After the test is completed, the movable plate 6 and the testing system continue to rise, and the protective doors 10 on both sides also continue to rise. The test seats 3 that have been tested flow out, while the test seats 3 to be tested flow in, thus completing the automated testing process.

[0097] In one embodiment, the linear drive component 4 includes:

[0098] The drive motor 401 is installed at the upper end of the vertical cavity in the middle of the mounting cavity;

[0099] One end of the ball screw 402 is connected to the power shaft of the drive motor 401;

[0100] A sliding member 403 is sleeved on the ball screw 402, and both sides of the sliding member 403 are respectively connected to the two toothed rods 5;

[0101] The support base 404 is installed in the middle vertical cavity, and the other end of the ball screw 402 is rotatably connected to the support base 404;

[0102] Multiple openings are provided on the support base 404, and the openings are used for the toothed rod 5 to pass through.

[0103] When the movable disc 6 and the testing system need to be raised or lowered, the drive motor 401 drives the ball screw 402 to rotate, and the sliding member 403 is also slidably mounted in the cavity, so that the sliding member 403 can be raised or lowered smoothly. The sliding member 403 drives the rack 5 to rise or fall, and the rack 5 drives the movable disc 6 and the testing system to rise or fall. At the same time, the rack 5 can mesh with the gear 7, driving the two gears 7 to rotate. The two gears 7 rotate in opposite directions, and through transmission, they drive the two rollers 8 to rotate in opposite directions. The pull rope 9 is also wound in opposite directions on the rollers 8 so that the pull rope 9 can extend to both sides of the mounting cavity. In this way, the pull rope 9 can be tightened or loosened at the same time. When the pull rope 9 is tightened, the protective door 10 rises, and when the pull rope 9 is loosened, the protective door 10 falls, thus completing the automated testing.

[0104] In one embodiment, the elastic reciprocating component 11 is installed in the test box 1, and the bottom of the elastic reciprocating component 11 is higher than the top of the test seat 3;

[0105] Mounting ring 12 is connected to the elastic reciprocating assembly 11, and the inner diameter of mounting ring 12 is greater than the width of test seat 3 and movable disk 6;

[0106] The pressing member 13 is mounted on the movable plate 6, and one end of the pressing member 13 extends above the mounting ring 12;

[0107] The telescopic air tube 14 has one end for connecting to an air source and the other end extending to one side of the mounting ring 12;

[0108] The flow equalization nozzle 15 is installed on the side wall of the mounting ring 12 and connected to the telescopic air pipe 14;

[0109] An inclined surface is provided on the mounting ring 12, located on the flow trajectory of the flow equalization nozzle 15, and inclined downwards;

[0110] When the protective door 10 descends to its lowest point, there is a gap between its lowest end and the mesh conveyor belt 2. The outer wall of the protective door 10 is covered with a sound-insulating membrane. The sound-insulating membrane can minimize external noise, thus reducing interference from other sounds during the test.

[0111] During the test, when the movable plate 6 rises and falls, it can drive the lowering component 13 to move. When the lowering component 13 moves downward, it can contact the mounting ring 12 and drive the mounting ring 12 and the flow equalization nozzle 15 to move downward. The telescopic air pipe 14 also moves downward. In this way, the flow equalization nozzle 15 can move to one side of the Bluetooth device. When it is necessary to test the effect of the Bluetooth device by blowing air, the blown air can be blown directly towards the Bluetooth device to ensure the accuracy of the Bluetooth device test. At the same time, it causes the elastic reciprocating component 11 to deform. When the movable plate 6 rises, the rebound force of the elastic reciprocating component 11 can also drive the mounting ring 12 and the flow equalization nozzle 15 back to their original positions.

[0112] When the airflow equalization nozzle 15 sprays air to simulate wind force, the airflow blowing across the Bluetooth device is directed towards the inclined surface, and then guided downwards by the inclined surface, passing through the grid conveyor belt 2 and the area below the protective door 10 before exiting the test chamber 1. This prevents the airflow from circulating inside the test chamber 1, thus ensuring more accurate measurement results when testing the effect of wind force on the Bluetooth device.

[0113] In one embodiment, the resilient reciprocating component 11 includes:

[0114] The limiting slide rail is vertically installed in the test box 1;

[0115] The moving part is matched and slidably connected to the limiting slide rail;

[0116] The connector has one end connected to the moving part and the other end connected to the mounting ring 12;

[0117] The reset spring has one end connected to the side wall of the connector and the other end connected to the inner wall of the test chamber 1.

[0118] When the mounting ring 12 moves, it drives the connecting parts and the moving parts, causing the moving parts to slide along the limit slide rail. At the same time, the moving parts and the limit slide rail can also slide stably together and will not fall off the limit slide rail. In this way, the mounting ring 12 can also be stably installed in the test box 1.

[0119] In one embodiment, it further includes:

[0120] The first transmission wheel 16 is connected to the side wall of the gear 7 and rotates coaxially with the gear 7;

[0121] The second transmission wheel 17 is connected to the winding roller 8 and rotates coaxially with the winding roller 8;

[0122] A transmission belt 18 is fitted between the first transmission wheel 16 and the second transmission wheel 17.

[0123] The transmission of the first drive wheel 16, the second drive wheel 17 and the drive belt 18 can ensure the stability of the transmission and enable the roller 8 to rotate in the same direction. Moreover, the drive belt 18 can be set to a longer length so that the rack 5 can smoothly drive the roller 8 to rotate when it moves up and down.

[0124] Multiple fixed pulleys are installed in the mounting cavity and contact the two pull ropes 9 respectively to avoid friction between the pull ropes 9 and the test box 1.

[0125] Using a fixed pulley can reduce the friction on the pull rope 9 and extend its service life.

[0126] Example 2: Refer to Figure 4 A testing system for Bluetooth devices, comprising:

[0127] The trigger module initiates the test when the active disk 6 and the test socket 3 come into contact.

[0128] The connection module enables wireless connection with the Bluetooth device under test;

[0129] Select the module and choose the audio information to be sent to the Bluetooth device under test;

[0130] The initial testing module sends the sound information to be tested to the Bluetooth device under test, causing the Bluetooth device under test to emit the sound to be tested;

[0131] The second test module sends the sound information to be tested back to the Bluetooth device to be tested, and at the same time controls the air source to emit interfering airflow from the flow equalization nozzle 15.

[0132] The collection module collects the measured sound information emitted by the Bluetooth device twice, and converts the measured sound information into measured text information respectively.

[0133] The comparison module uses each character as a measurement unit to compare the text information to be tested and the actual text information of the sound information to be tested according to the measurement unit.

[0134] The judgment module determines the similarity between the text information to be tested and the actual text information based on the comparison results of the comparison module. If the similarity reaches 90% or above, the test is judged to be passed.

[0135] The marking module marks Bluetooth devices that pass the test as qualified and Bluetooth devices that fail the test as unqualified.

[0136] When testing Bluetooth devices, once the movable disk 6 is moved to the designated position, the trigger module triggers the test system to start working. The Bluetooth device is connected to the test equipment. The test equipment can be placed outside the test box 1 to test the penetration of the Bluetooth connection, or it can be placed inside the test box 1 to facilitate signal transmission and thus test windproof performance.

[0137] During testing, the audio information to be tested can be randomly selected, or a specific audio information can be selected and input as the test text. Alternatively, audio can be recorded via voice input. Recorded audio can be in Mandarin or a dialect. This ensures the accuracy of speech recognition and guarantees that the Bluetooth device can recognize multiple dialects to meet diverse market demands.

[0138] During the initial test, the Bluetooth device plays the sound to be tested, while the data collection module collects the actual sound, converts it into text, and then compares it with the text to be tested to obtain a similarity score. If the similarity exceeds 90%, the Bluetooth device is considered qualified; otherwise, it is considered unqualified.

[0139] In the second test, airflow is ejected from the flow equalization nozzle 15 to create wind, simulating various headphone usage scenarios. For example, when driving or cycling, headphones are often worn, creating various wind noises around the headphones. The airflow size can also be adjusted using the flow equalization nozzle 15 to simulate wind force. After the airflow is ejected, the sound to be tested is transmitted to the Bluetooth device again. The Bluetooth device then emits sound, and the collection module collects the actual sound again, converts it into actual text, and compares it with the text to be tested to determine whether the similarity reaches or exceeds 90%.

[0140] Bluetooth devices with a similarity of 90% or higher are marked as qualified; otherwise, they are marked as unqualified. This marking method can automatically identify unqualified devices, which can greatly improve testing efficiency.

[0141] In one embodiment, the triggering module includes:

[0142] The first trigger is installed on the vertical rod, which is installed below the movable disk 6;

[0143] The second trigger is installed on the test seat 3 and corresponds to the position of the first trigger, so that when the movable disk 6 is lowered to the lowest position, the first trigger and the second trigger come into contact and trigger.

[0144] When the movable disk 6 moves toward the test seat 3, the vertical rod can contact the test seat 3, thereby causing the first trigger and the second trigger to contact, and the test starts working.

[0145] In one embodiment, selecting the audio information to be sent to the Bluetooth device under test includes:

[0146] A sound library was constructed, multiple text contents were designed, and for each text content, different types of sounds were recorded as test sounds. The different types of sounds included Mandarin and multiple dialects, and each dialect was used as a test sound.

[0147] A text is randomly selected from the sound database, and then the corresponding Mandarin or dialect is selected from that text as the sound to be tested;

[0148] The probability of selecting Mandarin is set to 70%.

[0149] In the process of building a sound library, you can use a voice with good Mandarin pronunciation as the sound information to be tested, or you can select a dialect or a voice with less standard Mandarin pronunciation as the sound information to be tested, in order to better reflect the actual situation in the market.

[0150] When selecting voices from the voice library, Mandarin has a 70% chance of being selected because most people speak Mandarin, making the test more representative.

[0151] When building a sound library, input the text content first; this will make the test results more accurate.

[0152] In one embodiment, the step of comparing the text information to be measured and the actual text information of the sound information to be measured according to the measurement unit, using each character as a measurement unit, includes:

[0153] The measured sound information is segmented into sentences based on the pause time in speech;

[0154] Identify the text in each measured audio sentence and count the number of texts per sentence;

[0155] The test text is compared sequentially to determine if the characters and their number in each measured audio sentence match the test text, and the number of successfully matched characters is counted.

[0156] When calculating similarity, a more precise number of characters is used as the recognition unit, and sentences are divided according to pauses and breaks. Then, the order of characters in each sentence is identified. This calculation can greatly improve the accuracy of recognition.

[0157] In one embodiment, the step of determining the similarity between the text information to be tested and the actual text information based on the comparison result of the comparison module, and determining that the test is passed if the similarity reaches 90% or above, includes:

[0158] The similarity score is obtained by dividing the number of successfully matched characters by the total number of characters in the test text.

[0159] Compare the similarity to 90%.

[0160] The similarity score can be set to 90%, or it can be set to 80%, or even 60%, because the general meaning of a sentence can be understood. However, for the sake of user comfort, we will use 90% as the detection standard here.

[0161] The Bluetooth device testing device of the present invention uses a gear 5 to lift and move the testing system closer to the test base 3, thereby testing the Bluetooth device. The whole process is automated, the action is stable, and the test results are good.

[0162] The movement of the rack 5 drives the protective door 10 to rise and fall automatically, thereby sealing the opening during the test and opening it after the test is completed. This does not hinder the free movement of the conveyor belt driving the test seat 3. Moreover, the whole process consumes little electrical energy and uses a mechanical structure to ensure stable operation.

[0163] The pressure component 13 is used in conjunction with the mounting ring 12 and the flow equalization nozzle 15 to add the effect of windproof testing in the process of achieving automated testing, thereby realizing the measurement of windproof headphones. The whole process adopts mechanical structure and transmission, which is stable and does not hinder the automation process. In addition, it can also reduce costs and save energy.

[0164] An automated testing system is used to test the wind resistance. During the testing process, multiple tests in multiple languages ​​are conducted to improve the accuracy of the measurements. This allows for the measurement of the Bluetooth device in the windproof headphones, ensuring that the headphones meet market requirements.

[0165] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
