[0002] As a representative of modern portable audio devices, Bluetooth speakers rely heavily on integrated Bluetooth audio modules for their core functionality. This module is a highly integrated electronic subsystem that acts as the "nerve center" of the speaker, responsible for handling key tasks such as wireless connectivity, audio signal processing, and device control.
[0003] Before leaving the factory, Bluetooth speakers require testing of their audio module functions. In existing technology, this is typically done manually before assembly, by connecting an external signal source to the audio module's motherboard and providing a switch signal to manually test various functions, such as wireless connectivity, button control, or LED illumination. During this manual testing, different signal sources are applied for different functions, and the results are obtained through observation and evaluation. It is evident that manual testing is not only cumbersome and inefficient, but also prone to human error due to its reliance on the testing personnel. Utility Model Content

The fixing fixture includes an upper pressure plate, a lower pad, and an upper pressure plate lifting mechanism. A button operation component and a conductive probe are inserted through the upper pressure plate. The lower pad is used to support the product to be tested. The upper pressure plate lifting mechanism can drive the upper pressure plate to rise and fall. When the upper pressure plate descends to a certain position, the button operation component abuts against the corresponding function button on the product to be tested, and the conductive probe is electrically connected to the conductive contact of the corresponding function module on the product to be tested.
[0006] The conductive probe is electrically connected to the control module via a wire. The control module is used to receive control signals from the host computer and control the activation and deactivation of various detection functions of the product under test according to the control signals from the host computer.

[0010] In some implementations, the control module includes a main control circuit board and an integrated circuit board. The main control circuit board has a storage unit capable of programming. The main control circuit board is electrically connected to a host computer via a USB cable. The main control circuit board is also electrically connected to the integrated circuit board. The integrated circuit board is electrically connected to the conductive probe via the wire.

[0029] This embodiment provides a functional testing device for an audio module, including a fixing fixture and a control module. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The fixing fixture includes an upper pressure plate 1, a clearance plate 2, a lower pad 3, a base plate 4, a base 5, an upper pressure plate lifting mechanism 6, and a bracket 7; the control module includes a main control circuit board and an integrated circuit board. The main control circuit board is electrically connected to the host computer via a USB cable, and the main control circuit board is electrically connected to the integrated circuit board. The main control circuit board is equipped with a storage unit that can be programmed, and the required detection software can be loaded onto the main control circuit board through programming.
[0030] The testing software mentioned in this embodiment is a software for testing the functionality of Bluetooth audio modules, installed on a computer (i.e., the host computer). Please refer to [link / reference]. Figure 3By connecting the computer to the USB terminal on the main control circuit board via a USB data cable, signals from the computer can be transmitted to the main control circuit board. The main control circuit board then transmits the signals to the integrated circuit board, which in turn controls the product to complete various functional tests based on the signals. After the software is installed, simply click the corresponding icon to display the main menu and perform the necessary software operations. This software can automatically control the testing of LED lights and button functions on the product under test. The software controls the motherboard of the audio module, which in turn controls the lighting of the LED lights and the on / off state of the buttons. It also saves and evaluates the test data, automatically completing the functional tests.
[0031] Please refer to the following for details. Figure 1 and Figure 4 The upper pressure plate 1 has several first through holes 11 and several second through holes 12 along its thickness direction. A button operation component 8 is inserted into the first through hole 11, and a conductive probe 9 is inserted into the second through hole 12. The lower pad 3 is used to support the product to be tested. The upper pressure plate lifting mechanism 6 can drive the upper pressure plate 1 to rise and fall. When the upper pressure plate 1 descends to a certain position, the product to be tested is clamped and fixed in the set position. At this time, the button operation component 8 abuts against the corresponding function button on the product to be tested, and the conductive probe 9 is electrically connected to the conductive contact of the corresponding function module on the product to be tested.
[0032] The integrated circuit board is electrically connected to the conductive probe 9 via wires. The main control circuit board sends the control signals from the host computer to the integrated circuit board. Based on the received signals, the integrated circuit board controls the product under test to automatically complete the corresponding functional tests.
[0033] A clearance plate 2 is fixed to the bottom of the upper pressure plate 1. The clearance plate 2 has a first clearance slot 21 for accommodating button operation components, conductive probes, and electronic devices on the product under test. The top surface of the lower pad 3 has a first mounting slot 31 for embedding the product under test. The bottom wall of the first mounting slot 31 has a second clearance slot 32 for accommodating electronic devices on the product under test. The top surface of the lower pad 3 has a second mounting slot 33 for embedding the main control circuit board. The bottom wall of the second mounting slot 33 has a third clearance slot 34 for accommodating electronic devices on the product under test.
[0034] The base plate 4 is fixed on the base 5, and the lower pad 3 is stacked on the base plate 4. In order to be suitable for products of different specifications, the lower pad 3 is fixed on the base plate 4 by detachable connection methods such as screws and buckles, so that the lower pad 3 can be removed and replaced.
[0035] The integrated circuit board is installed inside the base 5, while the main control circuit board is placed in the first mounting slot 31 of the lower pad 3. The product under test is placed on the second mounting slot 33 of the lower pad 3. Since the main control circuit board is not integrated with the integrated circuit board and is not installed in the base 5, it is easy to remove the main control circuit board for programming.
[0036] The base plate 4 has a third through hole 41 along its thickness direction. A connecting line is inserted into the third through hole 41. For example, the connecting line can be a copper probe or a copper wire. The bottom end of the connecting line contacts the contact on the integrated circuit and the top end contacts the contact on the main control circuit board, thereby realizing the electrical connection between the integrated circuit board and the main control circuit board.
[0037] After placing the product under test on the lower pad 3, the upper pressure plate lifting mechanism 6 can be operated to press down the upper pressure plate 1. When the upper pressure plate 1 descends to a certain position, the button operation component 8 can abut against the corresponding function button on the product under test, and the conductive probe 9 can achieve electrical connection with the conductive contact of the corresponding function module on the product under test.
[0038] Manually pressing the button 8 controls the opening and closing of the button on the product, thereby realizing the on / off detection of the button. Connecting a wire allows the control signal from the control module to be transmitted to the conductive probe 9. The conductive probe 9 transmits the signal to the corresponding functional module of the product through conductive contacts on the product, thereby turning the corresponding LED light on and off, thus completing the detection of that functional module.
[0039] As can be seen, the functional testing device of this embodiment can connect the signal source to each functional module in one go through the conductive probe 9, and automatically complete the testing of each function under the control of the host computer. The whole testing process is convenient, avoids errors caused by human operation, and has high testing accuracy.
[0040] Furthermore, to facilitate observation of the LED light, both the upper pressure plate 1 and the clearance plate 2 in this embodiment are made of light-transmitting or transparent materials; for example, transparent plastic can be used. In some other embodiments, the upper pressure plate 1 and the clearance plate 2 may also be made of opaque materials, with observation windows opened in the area corresponding to the LED light.
[0041] In this embodiment, the bracket 7 is vertically fixed to the base 5, and the upper pressure plate lifting mechanism 6 is mounted on the bracket 7. The upper pressure plate lifting mechanism 6 in this embodiment is manually operated. Specifically, the upper pressure plate lifting mechanism 6 includes a handle 61, a hinge seat 62, a hinge 63, and a telescopic pressure rod 64. The hinge seat 62 is fixed to the bracket 7, the handle 61 is hinged to the hinge seat 62 via the hinge 63, the top end of the telescopic pressure rod 64 is hinged to the hinge 63, and its bottom end is fixedly connected to the upper pressure plate. When the handle 61 is manually operated to swing up and down, it can drive the telescopic pressure rod 64 and the upper pressure plate 1 to move up and down.
[0042] It should be noted that this application does not limit the specific implementation of the upper pressure plate lifting mechanism 6. In other embodiments, the upper pressure plate lifting mechanism 6 can also adopt an electric drive scheme. For example, the upper pressure plate lifting mechanism includes a lifting motor, a transmission screw pair, a slide rail and a slider. The upper pressure plate is fixedly connected to the slider. When the lifting motor is working, it can drive the upper pressure plate to lift.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
