Description

Technical Field

[0001] The present invention relates to the technical field of wireless earphones and equipment testing, and in particular to a batch listening and radio frequency testing method for WIFI wireless earphones. Background Art

[0002] Currently, in addition to the headphone body, WIFI wireless headphones also have an independent wireless transmitter. This transmitter can be connected to a sound source, and thus to the headphones, allowing for a variety of sound sources. During the manufacturing phase of WIFI wireless headphones, we conduct listening tests to determine if the WIFI wireless headphones are qualified. In existing technologies, the main test requires a shortcut key on the WIFI wireless headphones to connect the test transmitter to the test headphones. Only after the connection is established can the test be performed.

[0003] Therefore, the existing WIFI wireless headset listening test is not only small in scale, high in cost and low in efficiency, but also requires a large number of testing instruments placed in different locations to perform sound quality testing, audio testing, etc. of WIFI wireless headsets. During the testing process, personnel are also required to supervise each test link. When using equipment to listen to headsets in batches, the quality of the RF device cannot be guaranteed, resulting in inaccurate listening test results, making it impossible to flexibly and large-scale batch listening and RF testing of WIFI wireless headsets.

[0004] Patent CN 103618987 A, which has been published, provides a device and method for batch listening radio frequency testing of Wi-Fi wireless headphones. During the test, a transmitter with verified good performance is required, but it is difficult to directly determine whether the transmitter has good performance. At the same time, when the transmitter and the headphones are connected, manual confirmation is required using buttons on the headphones. Intelligent integrated automatic detection is not completed, and manual supervision and inspection are required. In response to this situation, there is an urgent need for a highly efficient and automated method that can verify and determine the performance of the transmitter and then connect it automatically.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

[0063] Example 1:

[0064] according to Figure 1 As shown, an embodiment of the present invention provides a method for batch listening and radio frequency testing of WIFI wireless headsets, comprising:

[0065] Scanning and connecting to a wireless headset device under test within a preset range through a test transmitter preset in a shielding box, and determining a connection result; the shielding box includes at least a laser scanner, a test transmitter, and an attenuator; the connection result includes a connection success or a connection failure;

[0066] When the connection result is successful, the test signals of the wireless headset device to be tested and the test transmitter are read, and the test transmitter receives and converts the test signals to generate corresponding radio frequency signals;

[0067] The radio frequency signal is received and processed by the attenuator to determine the test result of the wireless headset device to be tested, and the test result is input to a preset evaluation model to generate a corresponding evaluation result.

[0068] The working principle of the above technical solution is:

[0069] In the existing technology, when testing WIFI wireless headphones, a transmitter with verified good performance is required, but it is difficult to directly confirm that the transmitter has good performance. At the same time, when the transmitter is connected to the headphones, manual confirmation is required through the buttons on the headphones. Intelligent integrated automatic detection is not completed, and manual supervision and inspection are required.

[0070] An embodiment of the present invention provides a batch listening and radio frequency testing method for WIFI wireless headphones. The method automatically connects by setting a trigger event when the headphone to be tested enters the device to be tested. The method scans and connects the wireless headphone device to be tested within a preset range through a preset test transmitter in a shielding box to determine the connection result. The test transmitter generally emits a wireless signal. A spectrum analyzer can be connected to the test transmitter to observe whether a signal is emitted. The shielding box includes at least a laser scanner, a test transmitter and an attenuator. The connection result includes a successful connection and a failed connection. When the connection result is a successful connection, the test signal of the wireless headphone device to be tested and the test transmitter is read. The test transmitter receives the test signal and performs signal conversion to generate a concurrent The corresponding radio frequency signal is output. The connection failure may generally be caused by signal failure, or the connection path is blocked or blocked. The reason for the connection failure can be inferred from the return code displayed by the device on the control terminal after the connection. The radio frequency signal is received and processed by the attenuator preset in the shielded line to determine the processing result. The attenuator is used to reduce the power level of the signal passing through it. The test result of the wireless headset device to be tested is determined through the processing result, and the test result is input to a preset evaluation model to generate a corresponding evaluation result. Through the test of the wireless headset to be tested, all headset devices can be evaluated to determine whether the headset is qualified, and the unqualified and qualified ones can be screened out. At the same time, an optimization plan for the headset is also proposed.

[0071] The beneficial effects of the above technical solution are:

[0072] This technical solution conducts batch listening tests on WiFi wireless headphones. By extensively connecting WiFi wireless headphones with RF equipment, the solution screens the headphones for conformity, improving product quality. This solution addresses issues such as high equipment costs, large test areas, low pairing efficiency, and the inability to conduct batch listening and RF testing. Furthermore, an evaluation module analyzes test data from the headphones, providing an optimization method for wireless headphones and reducing the rejection rate.

[0073] Example 2:

[0074] according to Figure 2 As shown, the present technical solution provides an embodiment, wherein a test transmitter preset in a shielding box is used to scan and connect to a wireless headset device to be tested within a preset range, and a connection result is determined, including:

[0075] When the preset test transmitter in the shielding box transmits a connection signal, the wireless headset device to be tested starts a preset trigger event to trigger a connection operation;

[0076] Reading the connection operation, screening the wireless headset devices to be tested that are successfully connected and the wireless headset devices to be tested that are failed to be connected;

[0077] Read the device model and device parameters of the wireless headset device under test that failed to connect;

[0078] Transfer the device model and device parameters of the wireless headset device under test that failed to connect to the preset table and convert the format to generate a connection failure device report;

[0079] The connection failure device includes feedback to a preset control terminal.

[0080] The working principle of the above technical solution is:

[0081] In the prior art, the connection of headphones is generally done by pressing the listening button. However, in this technical solution, when the headphones are connected to the device to be tested, the device sends a receiving program to the headphones to generate a trigger event for the headphones. This technical solution uses a preset test transmitter in the shielding box to scan and connect to the wireless headphone device to be tested within a preset range to determine the connection result. It can first be determined whether the headphones can be listened to normally. When the preset test transmitter in the shielding box transmits a connection signal, the wireless headphone device to be tested starts the preset trigger event and triggers the connection operation. The wireless headphones are uniformly set before being placed in the device to be tested, and can be used for batch connection. The signal emitted by the test transmitter is tested, thereby improving test efficiency and reducing test costs. By reading the connection operation, the wireless headset devices to be tested that have successfully connected and the wireless headset devices to be tested that have failed to connect are screened, and the device model and device parameters of the wireless headset devices to be tested that have failed to connect are read; the device model and device parameters of the wireless headset devices to be tested that have failed to connect are transmitted to a preset table, converted into a format table with a unified format for device signal statistics, and a report on the device with failed connection is generated; the device with failed connection is fed back to a preset control terminal, thereby performing an initial batch screening of the wireless headsets that have failed to connect, thereby improving the pass rate of the wireless headsets.

[0082] The beneficial effects of the above technical solution are:

[0083] This technical solution improves test efficiency, reduces test costs, and screens wireless headphone devices under test that have successfully connected and those that have failed to connect by uniformly setting the wireless headphone devices under test and batch-connecting the signals emitted by the test transmitter, thereby improving the pass rate of wireless headphones.

[0084] Example 3:

[0085] The present technical solution provides an embodiment, wherein the reading of the connection operation and screening of the wireless headphone devices to be tested that have successfully connected and the wireless headphone devices to be tested that have failed to connect include:

[0086] Read the device model and device parameters of the wireless headset device to be tested, and set the unique identifier of the wireless headset device to be tested;

[0087] Scanning a device location of a corresponding wireless headset device based on the unique identifier and a preset laser scanner;

[0088] The device position is compared with a preset device arrangement position, and the wireless headset device to be tested that fails to connect is triggered.

[0089] The working principle of the above technical solution is:

[0090] In the prior art, most headphone devices use manual listening to subjectively judge the sound quality of the product. Some companies require multiple testing equipment, which not only requires the headphones to be selected layer by layer, but also requires personnel to supervise the test results of each link. The present technical solution reads the connection operation to screen the wireless headphone devices to be tested that have successfully connected and the wireless headphone devices to be tested that have failed to connect. When the headphone is successfully connected, a corresponding successful connection mark will be displayed on the test device where the headphone is located, and the device model and device parameters of the wireless headphone device to be tested will be read. The unique identifier of the wireless headphone device to be tested is set, and the device position of the corresponding wireless headphone device is scanned based on the unique identifier and the preset laser scanner. Generally, the headphones are arranged into preset length and width dimensions, and the device position is compared with the preset device arrangement position to trigger the wireless headphone devices to be tested that have failed to connect. There is no need to subjectively judge the product sound quality through manual listening, and batch listening tests can be performed on the headphones.

[0091] The beneficial effects of the above technical solution are:

[0092] This technical solution can manage headphone devices on a large scale and improve the management efficiency of wireless headphones under test. Not only does it eliminate the need for manual listening and manual sound quality analysis, but through automated intelligent analysis, it can automatically perform batch listening and sound quality analysis on WiFi wireless headphones, improving resolution efficiency. At the same time, by recording locations and listening in batches, the differences in sound quality can be compared in real time, thereby improving the listening quality of wireless headphones.

[0093] Example 4:

[0094] This technical solution provides an embodiment, wherein the method further comprises: scanning and connecting a wireless headset device to be tested within a preset range through a preset test transmitter in a shielding box, and determining a connection result;

[0095] Sending a simulated sound signal to the wireless headset device under test through a preset simulation model;

[0096] The wireless headset device to be tested receives the simulated sound signal, turns on the noise reduction mode of the wireless headset device, and reads and burns the noise reduction parameters of the wireless headset device based on the noise reduction mode;

[0097] Based on the burned-in noise reduction parameters, the sound quality reception of the wireless headset device to be tested is evaluated, the sound quality performance parameters of the wireless headset device to be tested are determined, and the sound quality performance parameters are transmitted and stored in a preset evaluation model.

[0098] The working principle of the above technical solution is:

[0099] In the prior art, the sound quality of headphones is often judged by analyzing the parameters of the headphones through multiple instruments, but this is not accurate enough. The present technical solution uses a preset test transmitter in a shielding box to scan and connect to the wireless headphone device to be tested within a preset range. After determining the connection result, a simulated sound signal is sent to the wireless headphone device to be tested through a preset simulation model. The simulated sound signal is transmitted to the headphone to check whether the headphone can be listened to normally. The wireless headphone device to be tested receives the simulated sound signal and turns on the noise reduction mode of the wireless headphone device at the same time. Based on the noise reduction mode, the noise reduction parameters of the wireless headphone device are read and burned. The noise reduction parameters are used to determine whether the wireless headset device can receive sound signals normally and convert the sound quality of the sound signal. For example, when the wireless headset is making a call or recording, it is especially necessary to reduce the noise recorded in the sound signal to improve the clarity of the sound. Based on the burned-in noise reduction parameters, the sound quality reception of the wireless headset device to be tested is evaluated, the sound quality performance parameters of the wireless headset device to be tested are determined, and the sound quality parameters are transmitted to the preset evaluation model. The sound quality parameters include at least the quality of the sound, that is, the fidelity before and after the sound transmission, the three-frequency balance of the headset sound quality, the quality of the environmental noise reduction and the difference in timbre between different headsets.

[0100] The beneficial effects of the above technical solution are:

[0101] This technical solution uses multiple sound quality evaluation indicators and sound simulation training to obtain the sound quality parameters of the noise-reduced headphones, providing original data for the evaluation of headphone equipment, improving the qualification rate of headphone equipment, and providing optimization raw materials for the optimization of some headphones, which facilitates the analysis of the areas where headphone equipment needs to be improved.

[0102] Example 5:

[0103] according to Figure 3 As shown, the present technical solution provides an embodiment, wherein when the connection result is a successful connection, the test signals of the wireless headset device to be tested and the test transmitter are read, the test transmitter receives and converts the test signal, and generates a corresponding radio frequency signal, including:

[0104] When the connection result is successful, the control terminal sends a sound signal to the test transmitter;

[0105] sending the sound signal to a test transmitter, which converts the sound signal into a first radio frequency signal;

[0106] The first radio frequency signal is converted into an audio signal by a wireless headset device, and the audio signal is transmitted to a preset test model for testing to generate a corresponding test signal;

[0107] The test signal is received by a test transmitter, and signal conversion is performed on the test signal to generate and send out a corresponding radio frequency signal.

[0108] The working principle of the above technical solution is:

[0109] In the prior art, most headphone tests can only be conducted through human supervision to promptly identify quality issues with the headphones and screen out qualified or unqualified headphones. In this technical solution, when the connection result is successful, test signals from the wireless headphone device under test and the test transmitter are read. The test transmitter receives the test signal and performs signal conversion to generate and emit a corresponding radio frequency signal. When the connection result is successful, the control terminal sends a sound signal to the test transmitter. When the connection result is failed, if the failure threshold is exceeded, it indicates that there is a problem with the device under test or in the transmission of the sound signal, and the problem needs to be analyzed. When the connection is within the threshold, some of the headphones under test have problems and can transmit sound signals normally. The sound signals are sent to the test transmitter, which converts the sound signals into a first radio frequency signal. The first radio frequency signal is converted into an audio signal by the wireless headphone device and transmitted to a preset test model for testing to generate a corresponding test signal. The test model can test and analyze the audio signal, analyze the frequency response of the audio signal, and, under the influence of the frequency response, receive the test signal through the test transmitter, perform signal conversion on the test signal, and generate and emit a corresponding radio frequency signal.

[0110] The beneficial effects of the above technical solution are:

[0111] This technical solution avoids the problem of successful one-to-one pairing of headphones and transmitters, and then using a computer to control the transmitter to send signals to the headphones, solving the problems of low pairing efficiency and inability to perform batch listening and RF testing.

[0112] Example 6:

[0113] The present technical solution provides an embodiment, wherein the first radio frequency signal is converted into an audio signal by a wireless headset device, and the audio signal is transmitted to a preset test model for testing to generate a corresponding test signal;

[0114] determining, by a wireless headset device, whether the first radio frequency signal is a sound signal and determining a signal determination result;

[0115] When the result of the determination is that the first radio frequency signal is a sound signal, receiving and converting the first radio frequency signal into an audio signal;

[0116] When the result of the determination is that the first radio frequency signal is not a sound signal, uploading the first radio frequency signal to a user terminal connected to the wireless headset device, and converting the first radio frequency signal according to a preset format;

[0117] The audio signal is transmitted to a preset test model for testing to generate a corresponding test signal.

[0118] The working principle of the above technical solution is:

[0119] In the prior art, after the earphones perform noise reduction processing on the signal, it is impossible to verify whether the sound quality after the noise reduction processing meets the standard. The present technical solution uses a wireless earphone device to determine whether the first RF signal is a sound signal and determine the signal judgment result. Sometimes it is an interference signal transmitted by other interference waves in the environment, so the earphones need to identify the sound signal to facilitate sound noise reduction. When the judgment result is that the first RF signal is a sound signal, the first RF signal is received and converted into an audio signal; when the judgment result is that the first RF signal is not a sound signal, the first RF signal is uploaded to the user terminal connected to the wireless earphone device, and the first RF signal is converted according to a preset format. The audio signal can be transmitted to a preset test model for testing through filtering, noise reduction and frequency conversion to generate a corresponding test signal. The unified format facilitates testing of the test model and reduces testing costs.

[0120] The beneficial effects of the above technical solution are:

[0121] This technical solution uses a test model to test the audio signal and filter out unqualified audio to reduce noise. In the evaluation model, unqualified wireless headphones will be recorded to facilitate the separation of unqualified headphones, and at the same time, provide raw data for the optimization of the headphones.

[0122] Example 7:

[0123] The present technical solution provides an embodiment, wherein receiving and processing the radio frequency signal through an attenuator to determine a test result of the wireless headset device to be tested includes:

[0124] Receiving the radio frequency signal sent by the test transmitter through the attenuator preset in the shielded line, and obtaining the radio frequency test result corresponding to the radio frequency test;

[0125] Obtaining the communication speed and connection speed of the radio frequency test result, transmitting the communication speed and connection speed to a preset evaluation model, evaluating the radio frequency test result based on the evaluation index preset in the evaluation model, and generating a radio frequency test evaluation result;

[0126] Classify the corresponding RF test results based on the RF test evaluation results and determine the corresponding classification results;

[0127] The test result of the wireless headset device to be tested is determined based on the classification result.

[0128] The working principle of the above technical solution is:

[0129] This technical solution receives the RF signal of the test transmitter through a preset attenuator in the shielded line, and simultaneously receives the RF test results corresponding to the RF test, reads the corresponding communication speed and connection speed through the RF test results, provides original data for judging the quality of the headset, transmits the communication speed and connection speed to the preset evaluation model, evaluates the RF test results based on the evaluation indicators preset in the evaluation model, and generates RF test evaluation results. The evaluation indicators of the RF test of the headset include at least performance index test and reliability index test. The performance index test mainly tests the corresponding RF of the headset under changes in the external environment, humid and hot environment or high and low temperature environment, while the reliability index test mainly includes headset aging, electrostatic discharge test and vibration impact test, etc., to test the reliability of the headset RF, classify and process the RF test results through the RF test evaluation results, and determine the corresponding processing results. Classifying headsets with different RF test results is also a processing of the headset sound quality.

[0130] The beneficial effects of the above technical solution are:

[0131] This technical solution conducts RF tests on multiple indicators of wireless headphones to determine whether the wireless headphones meet RF conditions, providing a latitude evaluation index for headphone quality analysis, thereby improving the quality and optimization rate of the headphones.

[0132] Example 8:

[0133] The present technical solution provides an embodiment, wherein the communication speed and connection speed of the radio frequency test result are obtained, the communication speed and connection speed are transmitted to a preset evaluation model, and the radio frequency test result is evaluated based on the evaluation index preset in the evaluation model to generate the radio frequency test evaluation result, including:

[0134] The communication speed V for obtaining the RF test results TX and connection speed V LJ ;

[0135] Among them, V TX Represents the communication speed, V LJ Represents the connection speed, TX represents the abbreviation symbol of communication, and LJ represents the abbreviation symbol of connection.
