Description

Technical Field

[0001] This disclosure relates to the field of headphone testing technology, and in particular to a Bluetooth headphone listening test system and device. Background Technology

[0002] With the rapid development of audio technology, Bluetooth headphones, as an indispensable audio device in people's daily lives, are facing increasingly higher requirements for sound quality and performance.

[0003] Currently, in the manufacturing process of Bluetooth headphones, listening tests involve manual inspection of the headphone's UI and sound quality noise, among other things. A typical listening test flowchart is as follows: Figure 1 As shown, the testing process first requires connecting a professional Bluetooth adapter and test headphones to test the headphone button UI. When the headphones trigger a button, the Bluetooth adapter receives a message, allowing for verification of button functionality. When engineers write the headphone button test code, each button's information detection action must be repeatedly edited, making the operation complex (common buttons: play, pause, previous track, next track, volume up, volume down). Only after the button UI testing is complete can the music player be opened for music playback testing. After music playback testing, the recording device is then opened to test the microphone recording function. The entire process is time-consuming and slow.

[0004] In summary, the headphone listening test has drawbacks, such as the complicated Bluetooth connection process and the complicated headphone function test operation. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a Bluetooth headset listening test system and device that can achieve automatic connection and simultaneously monitor the button function status.

[0028] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0029] Please see Figure 2 and Figure 3 This is an embodiment of the headphone listening test system 10 of the present invention, comprising a host module 100, a Bluetooth adapter module 200, and a Bluetooth headphone module 300. The connection end of the host module 100 is electrically connected to the power input end of the Bluetooth adapter module 200, the pairing interaction end of the Bluetooth adapter module 200 is electrically connected to the pairing interaction end of the Bluetooth headphone module 300, and the data interaction end of the Bluetooth headphone module 300 is communicatively connected to the data acquisition end of the host module 100. Specifically, the data interaction end of the Bluetooth headphone module 300 and the data acquisition end of the host module 100 perform Bluetooth wireless communication. The Bluetooth adapter module 200 is used to automatically acquire nearby Bluetooth devices when electrically connected to the host module 100, and automatically establish a connection based on the address and name of the Bluetooth device. The host module 100 has a connection information acquisition unit 110 and a playback button integrated detection unit 120. The connection information acquisition unit 110 is used to read the address, name, and version information of the connected Bluetooth device, and the playback button integrated detection unit 120 is used by the host module 100 to simultaneously monitor the button function status and playback sound quality status of the Bluetooth device when connecting to the Bluetooth device.

[0030] Furthermore, the Bluetooth adapter module 200 employs an automatic Bluetooth communication library to automatically acquire the Bluetooth devices in the vicinity when electrically connected to the host module 100, and automatically establish a connection based on the address and name of the Bluetooth devices. In addition, the playback button integrated detection unit 120 employs a dynamic playback link library and a button sound monitoring database. The dynamic playback link library is used to control the button actions of the Bluetooth device and monitor the current button status. The button sound monitoring database is used to monitor the sound quality status and button action status during Bluetooth device playback, and uploads the corresponding status information to the host module 100. Thus, after the Bluetooth device is successfully connected, the host module 100 performs a playback action, automatically controls the button actions of the Bluetooth device, and simultaneously monitors the button status and sound quality status of the Bluetooth device. The data is then stored in the database and output from the display area of ​​the host module 100.

[0031] Specifically, the button actions for controlling Bluetooth devices include automatically controlling play / pause songs, automatically increasing / decreasing volume, automatically skipping to the previous / next track, and monitoring the playback sound quality and button status when the Bluetooth device is playing music. The playback sound quality includes music sound quality effects, noise effects, distortion levels, etc., while the button status includes whether the play / pause button, the increase volume button, the decrease volume button, the previous track button, and the next track button are responsive and the response rate, etc.

[0032] In this embodiment, the Bluetooth adapter module 200 adopts an automatic Bluetooth communication library, which can automatically scan and list the Bluetooth devices in the vicinity of common Bluetooth adapters, and establish a connection based on the address and name of the Bluetooth device. It can automatically connect without any command. When testing the headphones, since the system has an integrated playback button detection unit, the system can simultaneously monitor the button function status and playback sound quality status of the Bluetooth headphones, breaking the limitation of the step of detecting buttons first and then playback detection, thereby saving the overall steps of headphone testing.

[0033] It's understandable, combined Figure 4 As shown, when connecting a Bluetooth device, the Bluetooth adapter module 200 uses an automatic Bluetooth communication library. Specifically, it uses the "InTheHand.Net.Bluetooth" Bluetooth communication library method, which supports searching for nearby Bluetooth devices, obtaining device names, addresses, and other information, and establishing a connection through the Bluetooth address or name. In this way, the Bluetooth device can send or receive data with the host module 100. The Bluetooth device then functions as the Bluetooth headset module 300, thus removing the limitation of only using a professional Bluetooth adapter. It can be understood that when using the "InTheHand.Net.Bluetooth" Bluetooth communication library method, it can automatically check the Bluetooth status, automatically search for and pair Bluetooth devices, obtain the Bluetooth address and device name during connection, and remove the Bluetooth device when disconnecting. Furthermore, the playback button integrated detection unit 120 uses a dynamic playback link library and a button sound monitoring database. The dynamic playback library uses AxInterop.WMPLib technology, which can automatically control and monitor the button actions of the Bluetooth headset, such as automatically playing / pausing songs, automatically increasing / decreasing volume, and automatically skipping to the previous / next track. It also uploads button information to the host module 100. The button sound monitoring database uses Soundcheck (an audio testing system) to monitor the playback sound quality status when the Bluetooth device plays music and uploads the corresponding status information to the host. Using these two technologies, when testing the headset, music is played to monitor the playback sound quality. During music playback, the system automatically detects the sound quality of the Bluetooth headset, judges the sound quality and noise, and automatically controls the button actions to determine if the system responds to button commands. The aforementioned status information is then uploaded to the host module 100. Furthermore, the current data is displayed on the display area of ​​the host module 100 so that the operator is aware of the Bluetooth headset's quality status. In this way, the above steps reduce the complexity of connecting Bluetooth devices and save steps in headset testing.

[0034] like Figure 2 or Figure 3As shown, in one embodiment, the host module 100 also integrates a USB connector. The Bluetooth adapter module 200 is electrically connected to the host module 100 through the USB connector. Since the USB port has the characteristics of plug and play, it can be used without installing any driver. In this way, the Bluetooth adapter module 200 can be connected through the USB connector, realizing the plug-and-play effect without the need for complicated connection steps.

[0035] In one embodiment, the Bluetooth adapter module 200 has an HID communication protocol unit. Since the Bluetooth adapter module 200 is electrically connected to the host module 100 via a USB connector, it achieves a plug-and-play effect. By using the HID (Human Interface Device) communication protocol, HID communication between the Bluetooth adapter module 200 and the host module 100 can be realized. In this way, the two have the characteristics of low latency and high transmission efficiency when communicating, and the Bluetooth adapter module 200 can be used without the need for a dedicated driver installation.

[0036] like Figure 3 As shown, in one embodiment, the host module 100 further includes a headphone test mode switching unit 130. It can be understood that when the headphone test mode switching unit 130 is used, during the headphone testing process, the host module 100 can switch between different test modes by calling the mode switching function to control the Bluetooth device to perform single-earphone testing, dual-earphone testing, or stereo testing, thereby meeting the testing requirements of different devices.

[0037] like Figure 3 As shown, in one embodiment, the host module 100 also includes an error information collection unit 140. It is understood that during headset testing, when the server is unstable, congested, or has a large number of users accessing the system, detection timeouts or test failures due to internet instability are inevitable. When these situations occur, the system will output error information, which will be captured and saved to the log. Simultaneously, this error information will be displayed on the host module 100's display area so that operators are aware of and can address it, preventing Bluetooth headset testing problems from affecting the entire production test line and ensuring the Bluetooth headset testing process can proceed.

[0038] like Figure 3As shown, in one embodiment, the host module 100 further includes a test data report generation unit 150, which stores test data for each Bluetooth device. It is understood that after mass production of Bluetooth headsets, playback tests are typically performed on a batch of Bluetooth headsets. Each time a Bluetooth headset test is completed, the test data is saved to a test list, stored and processed in a queue, and then a detailed test report is generated to inform the operators. The test report information includes the Bluetooth headset's name, address, serial number (SN) code, identification code, version, button function status, sound quality, and whether it passed or failed. Furthermore, the test report is output in the display area of ​​the main control module, allowing operators to intuitively understand the quality status of the Bluetooth headsets, identify and resolve potential quality problems in the testing process, and ensure the normal operation of the headset production line.

[0039] In one embodiment, the host module 100 has a sound card reading unit, which is also used to read the sound card information of the Bluetooth device. In this embodiment, when the Bluetooth device is connected to the test computer via a Bluetooth adapter, the test computer will also read the corresponding sound card information of the Bluetooth device, such as the sound card version, sound card model, current sound card version, version update date, etc., and output the relevant information on its display screen so that the operator can view and understand it.

[0040] like Figures 2 to 4 As shown, in one embodiment, the host module 100 is a PC. In this embodiment, the PC serves as the core control unit of the system, establishing a bidirectional communication connection with the Bluetooth adapter module 200 and the Bluetooth headset module 300 through a dedicated interface (such as USB, Bluetooth antenna, etc.). Further, when the PC is electrically connected to the Bluetooth adapter, the PC acquires nearby Bluetooth devices through the Bluetooth adapter and establishes a connection based on the target device's address or name. Simultaneously, during the headset testing process, the PC monitors and acquires the button function status and playback sound quality status of the Bluetooth device to determine the status of each button and the sound quality of the music played, thereby determining whether the Bluetooth device can pass the test. Furthermore, the acquired nearby Bluetooth devices and the monitored and acquired button function status and playback sound quality status of the Bluetooth device are displayed through the PC's human-machine interface (HMI), allowing operators to view the headset testing status, test time, sound quality waveform, etc., in real time. After completing a single headset test, the operator can know the status of the headset to confirm whether it has passed the test.

[0041] In one embodiment, the Bluetooth adapter module 200 is a Bluetooth adapter. Compared to a professional Bluetooth adapter, using a regular Bluetooth adapter is less expensive. Professional Bluetooth adapters use more protocols and have more interfaces, but when testing Bluetooth headsets, they require commands to connect to the headset, making the operation more complicated. In contrast, a regular Bluetooth adapter uses an automatic Bluetooth communication library, specifically the "InTheHand.Net.Bluetooth" Bluetooth communication library method. This technology can search for nearby Bluetooth devices, obtain device names, addresses, and other information, and establish connections via Bluetooth addresses or names. Communication can be achieved without delving into the details of the Bluetooth protocol, making the operation simpler.

[0042] This disclosure also provides a headphone hearing test device, including the headphone hearing test system 10 of any of the above embodiments.

[0043] Compared with the prior art, this disclosure has at least the following advantages:

[0044] The aforementioned headphone listening test system 10 uses an automatic Bluetooth communication library in its Bluetooth adapter module 200. This allows the system to automatically scan and list nearby Bluetooth devices using common Bluetooth adapters, and establish a connection based on the Bluetooth device's address and name. This connection can be established automatically without any commands. When testing headphones, the system has an integrated playback button detection unit, which enables the system to simultaneously monitor the button function status and playback sound quality status of the Bluetooth headphones. This eliminates the limitation of testing buttons first and then playback, thus saving on the overall headphone testing steps.

[0045] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
