DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the specific embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. It is understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. It should also be noted that, for ease of description, only some, but not all, of the contents related to the present application are shown in the accompanying drawings. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe each operation (or step) as a sequential process, many of the operations therein can be implemented in parallel, concurrently or simultaneously. In addition, the order of the operations can be rearranged. The process can be terminated when its operation is completed, but it can also have additional steps not included in the accompanying drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.
[0034] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.
[0035] In the more common existing implementation method, the mainboard that comes with the microphone board is equipped with tooling and software that are compatible with the microphone board, and the microphone board is tested through the mainboard that comes with the microphone board. Precisely because the mainboard and the microphone board are matched, the tooling and software of the mainboard can only be used to test the corresponding microphone board, and cannot be used to test other types of microphone boards. For example, different microphone boards are equipped with different types of FFC (Flexible Flat Cable) cable sockets (10pin, 15pin, 20pin and 30pin, etc.), and the FFC cable socket set on the mainboard is the same as the corresponding microphone board (such as the microphone board and the mainboard are both equipped with 10pin FFC cable sockets), so the mainboard cannot connect to the microphone board with other types of FFC cable sockets (such as the mainboard with a 10pin FFC cable socket cannot connect to the microphone board with a 15pin FFC cable socket). Secondly, different microphone boards are compatible with different supply voltages (typically 1.8V or 3.3V), while the supporting motherboard's supply voltage is adapted to the corresponding microphone board. This means the supporting motherboard can only provide a single supply voltage, making it unable to power microphone boards that require a different supply voltage. Finally, microphone boards typically use PDM (Pulse Density Modulation) and I2S (Inter-IC Sound), and different communication types require different audio parsing software. The supporting motherboard's audio parsing software is adapted to the communication type of the corresponding microphone board (e.g., if the microphone board's communication type is I2S, the supporting motherboard's audio parsing software is used to parse I2S audio data; if the microphone board's communication type is PDM, the supporting motherboard's audio parsing software is used to parse PDM audio data). Therefore, the supporting motherboard cannot parse audio data transmitted by microphone boards with other communication types. The supporting motherboard can only serve as a test board for the corresponding microphone board, making it less versatile. Furthermore, the supporting motherboard also handles other functions besides testing. During startup, the supporting motherboard must activate the driver modules for these other functions one by one. This results in a long startup time for the supporting motherboard, which in turn causes a longer test time for the microphone board and lowers test efficiency. Because different motherboard configurations are equipped with different audio analysis software, test equipment cannot standardize test logic when connected to different motherboard configurations, affecting test efficiency.
[0036] In order to solve the above problems, this embodiment provides a microphone test board, which is compatible with microphone boards of different socket types through the first wiring socket and the first thimble socket, and parses the audio data used by the microphone board through the audio chip, so as to have the ability to test a variety of microphone boards, ensuring the versatility of the microphone test board. The microphone test board is dedicated to testing the microphone board. It does not need to start too many driver modules at startup. The startup time of the microphone test board is short, and it can even achieve a plug-and-test effect, effectively shortening the test time of the microphone board and improving the test efficiency of the microphone board. The microphone test board unifies the audio analysis software of microphone boards of different communication types, so that the microphone test board can parse the audio data collected by microphone boards of different communication types, and transmit the parsed data to the test equipment. The test equipment can perform performance testing on the data collected by different microphone boards transmitted by the microphone test, realize the standardization of the test logic, and further improve the test efficiency.
[0037] Figure 1 A schematic diagram of the structure of a microphone test board provided in an embodiment of the present application is given. Figure 1 As shown, the microphone test board 10 includes an audio chip 11, a first cable socket 12, and a first ejector pin socket 13. The audio chip 11 is connected to the first cable socket 12 and the first ejector pin socket 13; the first cable socket 12 is used to connect to the second cable socket of the microphone board 20, and the first ejector pin socket 13 is used to connect to the test ejector pin of the microphone board 20. The audio chip 11 is used to parse the audio data collected by the microphone board 20.
[0038] The first cable socket 12 is an FFC cable socket provided on the microphone test board 10. The second cable socket is an FFC cable socket provided on the microphone board 20. For example, if the first cable socket 12 and the second cable socket are of the same type, a wire can be connected to the first cable socket 12 and the second cable socket to establish a communication connection between the microphone test board 10 and the microphone board 20. The microphone board 20 can then transmit the collected audio data to the audio chip 11 of the microphone test board 10 via the second cable socket and the first cable socket 12. The audio chip 11 then analyzes the audio data collected by the microphone board 20.
[0039] The first ejector pin socket 13 is an ejector pin socket for testing provided on the microphone test board 10. The test ejector pin is a test point provided on the microphone board 20, which can be a clock pin and / or a communication pin of the microphone board 20. Exemplarily, the test ejector pin of the microphone board 20 can directly contact the ejector pin socket, that is, the ejector pin socket and the test ejector pin are not connected by wire. When the second wiring socket of the microphone board 20 and the first wiring socket 12 of the microphone test board 10 are not compatible, the test ejector pin of the microphone board 20 can be plugged into the ejector pin socket of the microphone test board 10, thereby establishing a communication connection between the microphone board 20 and the microphone test board 10. Afterwards, the microphone board 20 can transmit the collected audio data to the audio chip 11 of the microphone test board 10 through the test ejector pin and the ejector pin socket, and the audio chip 11 parses the audio data collected by the microphone board 20.
[0040] Because microphone test board 10 is equipped with a first cable socket 12 and a first ejector pin socket 13, they can connect to the second cable socket or test ejector pin of microphone board 20. Most microphone boards 20 on the market have test ejector pins and a second cable socket as test interfaces. Therefore, microphone test board 10 is compatible with the test interfaces of most microphone boards 20 on the market, and the interface tooling of microphone test board 10 is highly versatile. In addition, the provision of first ejector pin socket 13 can effectively save wire used to connect the cable sockets, reducing the cost of wire usage.
[0041] Furthermore, the audio chip 11 of the microphone test board 10 is provided with an I2S communication mode and a PDM communication mode. In the I2S communication mode, the audio chip 11 can parse the I2S audio data transmitted by the microphone board 20 through the I2S audio parsing software. In the PDM communication mode, the audio chip 11 can parse the PDM audio data transmitted by the microphone board 20 through the PDM audio parsing software. Most microphone boards 20 on the market have a communication type of I2S or PDM, so the microphone test board 10 is compatible with the communication types of most microphone boards 20 on the market, and the audio parsing software of the microphone test board 10 is highly versatile.
[0042] Since the microphone test board 10 has highly versatile interface tooling and audio analysis software, it can test most of the microphone boards 20 on the market, and the microphone test board 10 has high testing versatility.
[0043] In one embodiment, the microphone test board 10 is provided with various types of first cable sockets 12. For example, Figure 2 Schematic diagram of the first side of the microphone test board provided in the embodiment of the present application. Figure 2As shown, the first side (which can be the front or back) of the microphone test board 10 is provided with a 10-pin FFC cable socket 121, a 15-pin FFC cable socket 122, a 20-pin FFC cable socket 123, and a 30-pin FFC cable socket 124. At this time, the microphone test board 10 supports the connection of microphone boards 20 provided with 10-pin, 15-pin, 20-pin, and 30-pin FFC cable sockets, and supports the connection of almost all types of microphone boards 20 on the market. In this embodiment, by providing multiple types of first cable sockets 12 on the microphone test board 10, even if the microphone board 20 is not provided with test pins, the microphone test board 10 can establish a connection with the second cable sockets of various types of microphone boards 20 through the first cable sockets 12, thereby further improving the versatility of the microphone test board 10.
[0044] In one embodiment, the microphone test board 10 is provided with a plurality of first thimble sockets 13 . Figure 3 Schematic diagram of the second side of the microphone test board provided in the embodiment of the present application. Figure 3 As shown, the second side of the microphone test board 10 (the opposite side of the first side) is provided with a plurality of first thimble sockets 13, and the spacing between two adjacent first thimble sockets 13 is 2 mm. The microphone test board 10 can be connected to multiple microphones through the plurality of first thimble sockets 13. Since the first thimble sockets 13 are small in area and small in spacing, the microphone test board 10 can be provided with more than ten or even twenty first thimble sockets 13. A microphone board 20 includes multiple microphones, and different types of microphone boards 20 correspond to different numbers of microphones. In this embodiment, by providing a plurality of first thimble sockets 13 on the microphone test board 10, the microphone test board 10 can support testing of microphone boards 20 with different numbers of microphones, thereby improving the versatility of the microphone test board 10.
[0045] It should be noted that the microphone test can support the connection of a maximum of 32 microphones when multiple types of first thimble sockets 13 and multiple first thimble sockets 13 are set.
[0046] Optionally, the first cable socket 12 and the first pin socket 13 are respectively arranged on the front and back sides of the microphone test board 10. For example, referring to Figure 2 and Figure 3 The first side where the first cable socket 12 is located can be the front side of the microphone test board 10, and the second side where the first ejector pin socket 13 is located can be the back side of the test board. This embodiment separates the first cable socket 12 and the first ejector pin socket 13 on the front and back sides of the microphone test board 10 to free up more space for connecting more microphones, thereby improving the versatility of the microphone test board 10.
[0047] In one embodiment, in addition to being used to parse the audio data collected by the microphone board 20, the audio chip 11 can also test the performance of the microphone board 20 based on the parsed audio data. However, if the audio chip 11 also tests the performance of the microphone board 20, then the microphone test board 10 must also start the driver module of the test software when it starts up, which will extend the startup time of the microphone test board 10 and affect the test efficiency. In addition, the computing power of the audio chip 11 is lower than that of the test equipment 30 (such as a computer or host computer), which will also affect the test efficiency when it is used to test the performance of the microphone board 20.
[0048] In order to shorten the startup time of the microphone test board 10 and improve the test efficiency, the audio chip 11 can be communicatively connected to the test equipment 30. After parsing the audio data collected by the microphone board 20, the audio chip 11 transmits the parsed audio data to the test equipment 30. The test equipment 30 tests the performance of the microphone board 20 based on the data transmitted by the audio chip 11. In this embodiment, the microphone test board 10 also includes a communication interface 14. The first end of the communication interface 14 is connected to the audio chip 11, and the second end of the communication interface 14 is used to connect to the test equipment 30. The communication interface 14 is used to transmit the audio data parsed by the audio chip 11 to the test equipment 30. Optionally, the communication interface 14 can be a USB interface. In this embodiment, the audio data parsed by the audio chip 11 is transmitted to the test equipment 30 through the communication interface 14, so that the test equipment 30 can perform performance testing of the microphone board 20 based on the audio data transmitted by the communication interface 14, thereby sharing the processing pressure of the audio chip 11 and improving the data processing efficiency and startup efficiency of the audio chip 11.
[0049] refer to Figure 2 The communication interface 14 and the first cable socket 12 are arranged together on the first side of the microphone test device 30. The communication interface 14 is arranged at the edge of the microphone test board 10 to facilitate connection with the test device 30. After receiving the audio data transmitted by the first cable socket 12 or the ejector pin socket, the audio chip 11 parses the audio data using audio parsing software and then transmits the parsed audio data to the test device 30 via the communication interface 14. The test device 30 obtains the parsed audio data from the communication interface 14 and tests the pickup amplitude and consistency of the microphone board 20 based on the parsed audio data.
[0050] Optionally, the audio chip 11 supports I2S communication mode and PDM communication mode. The user can switch the communication mode of the audio chip 11 through the test device 30 according to the communication type of the microphone board 20 plugged into the microphone test board 10. For example, when the communication type of the microphone board 20 is I2S, the test device 30 sends an I2S mode switching instruction to the audio chip 11 through the USB interface, and the audio chip 11 switches to the I2S communication mode according to the I2S mode switching instruction, so that when the I2S audio data transmitted by the microphone board 20 is received, the I2S audio data is parsed by the I2S audio parsing software. When the communication type of the microphone board 20 is PDM, the test device 30 sends a PDM mode switching instruction to the audio chip 11 through the USB interface, and the audio chip 11 switches to the PDM communication mode according to the PDM mode switching instruction, so that when the PDM audio data transmitted by the microphone board 20 is received, the PDM audio data is parsed by the PDM audio parsing software.
[0051] In one embodiment, the microphone test board 10 further includes a first power supply module 16 and a power supply socket 15. The first power supply module 16 is connected to the power supply socket 15. The power supply socket 15 is used to plug in an external power supply. The first power supply module 16 is used to transmit the power transmitted by the external power supply to the microphone test board 10. Figure 2 , the first power supply module 16 and the power supply socket 15 are arranged on the first side of the microphone test board 10. After the power supply socket 15 is connected to a 220V external power supply, the first power supply module 16 converts the voltage of the external power supply into the 12V voltage required by the microphone test board 10 and supplies power to various components of the microphone test board 10, such as the audio chip 11. Since the microphone test board 10 is only used to test the microphone board 20, its power supply socket 15 can be connected to the external power supply all the time, that is, the microphone test board 10 is always in a powered state, and the microphone board 20 can be plugged and tested. In this embodiment, the microphone test board 10 is supplied with power separately through the power supply socket 15 and the first power supply module 16, so that the microphone test board 10 is always in a powered state, which saves the startup time of the microphone test board 10, and the microphone board 20 can be plugged and tested, which effectively improves the test efficiency.
[0052] Optionally, the microphone test board 10 further includes a cylindrical socket 17, which is used to connect to an external power source and transmit the electrical energy from the external power source to the microphone test board 10. And / or, the microphone test board 10 further includes a second thimble socket 19, which is used to connect to an external power source and transmit the electrical energy from the external power source to the microphone test board 10. The second thimble socket 19 is a thimble socket provided on the microphone test board 10 for connecting to an external power source. Figure 2 The cylindrical socket 17 is provided on the first surface of the microphone test board 10. Figure 3, the second thimble socket 19 is arranged on the second surface (opposite to the first surface) of the microphone test board 10. After the cylindrical socket 17 or the second thimble socket 19 is connected to a 12V external power supply, power is supplied to other devices in the microphone test board 10 based on the electric energy provided by the external power supply. For example, the cylindrical socket 17 or the second thimble socket 19 is connected to the power supply terminal of the audio chip, and power can be supplied to the audio chip when the cylindrical socket 17 or the second thimble socket 19 is connected to a 12V external power supply. When there is no connectable 220V external power supply around the microphone test board 10, a 12V external power supply can be connected through the cylindrical socket 17 or the second thimble socket 19, so as to avoid the microphone test board 10 from failing to work due to lack of an adapted external power supply, thereby improving the applicability of the microphone test board 10.
[0053] In one embodiment, the microphone test board 10 further includes a second power supply module 18, a first end of the second power supply module 18 is connected to the first power supply module 16, and a second end of the second power supply module 18 is used to connect to the power interface of the microphone board 20, and the second power supply module 18 is used to supply power to the corresponding connected microphone board 20. Figure 2 , the second power supply module 18 is arranged on the first side of the microphone test board 10. After the microphone test board 10 is connected to the external power supply and the microphone board 20, the first power supply module 16 provides a 12V voltage to the second power supply module 18. The second power supply module 18 converts the 12V voltage input by the first power supply module 16 into the 3.3V or 1.8V voltage required by the microphone board 20, and outputs it to the power interface of the microphone board 20 to supply power to the microphone board 20. After receiving power, the microphone board 20 can collect audio data and transmit the audio data to the microphone test board 10 through the second wiring socket or test pin. In this embodiment, the microphone board 20 is powered by the second power supply module 18 of the microphone test board 10, so as to avoid the microphone board 20 having to be powered on by the matching mainboard, simplifying the test operation of the microphone board 20, and achieving the plug-and-test effect of the microphone board 20, thereby improving the test efficiency.
[0054] Optionally, when the microphone test board 10 is provided with a cylindrical socket 17 or a second thimble socket 19, the cylindrical socket or the second thimble socket is connected to the second power supply module 18. When the cylindrical socket 17 or the second thimble socket 19 is connected to an external 12V power supply, the cylindrical socket 17 or the second thimble socket 19 provides a 12V voltage to the second power supply module 18. The second power supply module 18 converts the 12V voltage transmitted by the cylindrical socket 17 or the second thimble socket 19 into the 3.3V or 1.8V voltage required by the microphone board 20, and outputs it to the power interface of the microphone board 20 to supply power to the microphone board 20.
[0055] Optionally, the second power supply module 18 includes a power supply switching switch, which is used to switch the output voltage of the second power supply module 18. Exemplarily, when the voltage used by the microphone board 20 is 3.3V, the second power supply module 18 can be switched to an output voltage of 3.3V through the power supply switching switch, so as to supply power to the microphone board 20 through the 3.3V output voltage. When the voltage used by the microphone board 20 is 1.8V, the second power supply module 18 can be switched to an output voltage of 1.8V through the power supply switching switch, so as to supply power to the microphone board 20 through the 1.8V output voltage. In this embodiment, the output voltage of the second power supply module 18 is switched by the power supply switching switch to meet the power supply requirements of different types of microphone boards 20, thereby improving the versatility of the microphone test board 10.
[0056] Based on the above embodiments, Figure 4 1 is a schematic diagram of the structure of a microphone test system provided in an embodiment of the present application. The microphone test system includes a test device 30 and the microphone test board 10 described in the above embodiment, and the test device 30 is connected to the microphone test board 10. Figure 4 As shown, the test device 30 is connected to the audio chip 11 of the microphone test board 10 through the communication interface 14 of the microphone test board 10, and the audio chip 11 is connected to the microphone board 20 through the first wiring socket 12 and / or the first test pin of the microphone test board 10. The audio chip 11 can obtain the audio data collected by the microphone board 20 through the first sorting socket and / or the first test pin, parse the audio data, and transmit the parsed audio data to the test device 30 through the communication interface 14. The test device 30 tests the microphone board 20 based on the audio data transmitted by the communication interface 14.
[0057] In summary, the microphone test board 10 and microphone test device 30 provided in the embodiments of the present application can be connected to a microphone board 20 equipped with a second cable strip via a first cable socket 12, and can be connected to a microphone board 20 equipped with test pins via a first pin socket 13. The tooling of the microphone test board 10 can be adapted to microphone boards 20 equipped with different types of sockets. The microphone test board 10 can also parse the audio data collected by the microphone board 20 via an audio chip 11. Therefore, the microphone test board 10 has the ability to test a variety of microphone boards 20, and the microphone test board 10 is highly versatile. The audio chip 11 of the microphone test board 10 is mainly used to parse audio data and is configured with almost no other functions. Therefore, the microphone test board 10 does not need to start too many driver modules during startup, resulting in a short startup time, which can effectively shorten the microphone and even achieve a plug-and-test effect, effectively shortening the test time of the microphone board 20 and improving the test efficiency of the microphone board 20. Therefore, the microphone test board 10 can solve the problems of poor versatility and low efficiency of the matching motherboard test in the prior art.
