Description

Technical Field

[0001] This invention relates to the field of intelligent sound pressure detection, and more particularly to a sound pressure detection method and a sound detection system. Background Technology

[0002] Sound pressure level (SPL) testing of headphones requires simulating the process of headphones inside a listener's ear canal to evaluate the headphones' sound performance. This process necessitates setting up a dedicated environment and supporting equipment such as head and body simulation devices to achieve highly standardized and scientific testing, that is, to simulate the acoustic environment of a real human wearing headphones as closely as possible.

[0003] In the routine inventory of enterprise operations, the original records of sound pressure level (SPL) testing are a typical example, prone to confusion or omissions. Once the test results are confirmed, it is not feasible to trace back to check whether the original records from several days or months ago are confused or missing. Furthermore, relying solely on management systems to standardize the SPL testing process is not easily implemented in practice. Therefore, this application proposes a SPL testing method and a sound detection system. Summary of the Invention

[0004] In a first aspect, the present invention proposes a sound pressure level detection method, the method being used in a control unit, the method comprising: S1, obtaining an instruction to enable the sound pressure level detection software to be started; S2, completing the sound pressure level detection step through the cooperation of the sound pressure level detection software and the earphone under test; and S3, storing the detection data results corresponding to the sound pressure level detection.

[0005] The further technical solution is that step S1 includes: S11, obtaining a sound pressure detection reservation instruction, so that the sound pressure detection software switches from an unstartable state to a startable state.

[0006] A further technical solution is that the control unit connects a host and a slave unit. The host is located in the main laboratory, and the slave unit is located in the sound pressure chamber. There is at least one office space between the main laboratory and the sound pressure chamber. Step S11 includes: obtaining a sound pressure testing reservation instruction from the host in the main laboratory and transmitting the sound pressure testing reservation instruction to the slave unit in the sound pressure chamber. After receiving the sound pressure testing reservation instruction, the sound pressure testing software in the slave unit switches from an unstartable state to an startable state.

[0007] A further technical solution is that step S2 includes: S21, obtaining a first sound pressure level detection result when the earphone under test is in working state for the first time; S22, obtaining a second sound pressure level detection result when the earphone under test is in working state for the second time; S23, obtaining an incremental sound pressure level detection result set when the earphone under test is in working state subsequently; S24, processing the first sound pressure level detection result, the second sound pressure level detection result, and the incremental sound pressure level detection result set according to a preset sound pressure rule, and obtaining a sound pressure level calculation result.

[0008] A further technical solution is that the control unit is connected to the sensing unit, and the sensing unit is located on the simulated ear of the head-body simulation device; the S21 step includes: S501, sensing the state of the sensing unit of the head-body simulation device to determine whether the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S502, if the head-body simulation device in the sound pressure chamber is not in the state of wearing the earphone under test, keeping the detection interface of the host in the main laboratory in the locked interface; S503, if the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test, that is, the earphone under test is working for the first time, unlocking the detection interface of the host in the main laboratory to the active interface; S504, receiving the first sound pressure detection command from the slave device in the sound pressure chamber, and continuously for a preset standard time to obtain the first sound pressure detection result; S505, after obtaining the first sound pressure detection result, controlling the detection interface of the host in the main laboratory to switch back to the locked interface.

[0009] The further technical solution is as follows: Step S22 includes: S601, determining whether the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S602, if the head-body simulation device in the sound pressure chamber is not in the state of wearing the earphone under test, keeping the detection interface of the host in the main laboratory locked; S603, if the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test, that is, the earphone under test is in working state for the second time, unlocking the detection interface of the host in the main laboratory and putting it into the active interface; S604, receiving the second sound pressure detection command from the slave device in the sound pressure chamber, and continuously for a preset standard time to obtain the second sound pressure detection result; S605, after obtaining the second sound pressure detection result, controlling the detection interface of the host in the main laboratory to switch back to the locked interface.

[0010] The further technical solution is that step S23 includes: S701, determining whether the head and body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S702, referring to the mode of steps S502 to S505, obtaining at least three sound pressure detection results in sequence when the earphone under test is in the working state, and after obtaining the results, switching back to the locking interface, and taking at least three sound pressure detection results as the incremental sound pressure detection result set.

[0011] The further technical solution is that step S3 includes: S31, determining whether the digital handwriting of the original record corresponding to the sound pressure detection is recognized; S32, if the digital handwriting of the original record is recognized, filling the detection data result corresponding to the digital handwriting into the detection column of the host, and storing the detection data result in the detection column.

[0012] In a second aspect, the present invention proposes a sound detection system, wherein the control unit of the sound detection system is used to perform the sound pressure detection method as described in the first aspect.

[0013] During routine reviews of their work, the inventors discovered that the original records of sound pressure level (SPL) tests were prone to confusion or omissions. A major reason for this was the strict requirements for the location of the SPL chamber. As a result, given the limited space in the main laboratory, most SPL chambers needed to be set up separately (not physically adjacent to the main laboratory). Consequently, the management standards of the main laboratory could not be easily extended to the SPL chamber. Furthermore, since technical personnel were not stationed in the SPL chamber at all times, they only entered the SPL chamber with headphones when necessary, which led to confusion in the original records.

[0014] In summary, sound pressure level (SPL) testing of headphones requires simulating the process of headphones inside a listener's ear canal in order to evaluate the headphones' sound performance. This process requires a dedicated environment and supporting head and body simulation devices to achieve highly standardized and scientific testing, i.e., to simulate the acoustic environment of a real human wearing headphones as closely as possible. Based on this, the solution described in this application, through the control of the sound pressure level testing software, can make the sound pressure level testing of headphones more standardized and controllable.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0023] Example 1

[0024] Please see Figures 1 to 3 The diagram illustrates a sound pressure level (SPL) detection method provided by an embodiment of the present invention. The method is used in a control unit and includes: S1, obtaining an instruction to enable the SPL detection software to start; S2, completing the SPL detection steps through the cooperation of the SPL detection software and the earphone under test; and S3, storing the detection data results corresponding to the SPL detection. Furthermore, this SPL detection method is used by technicians to perform SPL detection. Since most teams in the industry do not have dedicated SPL detection engineers, the SPL detection work for earphones is generally performed by technicians with expertise in SPL technology, who come to the SPL room and perform multiple roles. The above solution is an intelligent control method for SPL detection. By controlling the SPL detection software, the SPL detection work for earphones can be made more standardized and controllable.

[0025] In one embodiment, step S1 includes: S11, obtaining a sound pressure detection reservation instruction, so that the sound pressure detection software switches from an unstartable state to an startable state.

[0026] In one embodiment, the control unit connects a host and a slave unit. The host is located in the main laboratory, and the slave unit is located in the sound pressure chamber. There is at least one office space between the main laboratory and the sound pressure chamber. Step S11 includes: obtaining a sound pressure testing reservation instruction from the host in the main laboratory and transmitting the sound pressure testing reservation instruction to the slave unit in the sound pressure chamber. After receiving the sound pressure testing reservation instruction, the sound pressure testing software in the slave unit switches from an unstartable state to an startable state.

[0027] In the above scheme, there is at least one office space between the main laboratory and the sound pressure chamber, that is, the door of the sound pressure chamber is not connected to the main laboratory (the main laboratory space is limited, and the sound pressure chamber has strict space requirements, so it is set up separately). The management standards of the main laboratory cannot be easily extended to the sound pressure chamber. Optionally, there is at least one hundred meters between the main laboratory and the sound pressure chamber, and technicians need to carry paper copies of the original records from the main laboratory to the sound pressure chamber to carry out sound pressure testing.

[0028] Furthermore, the acquisition of the sound pressure test reservation instruction originating from the host computer of the main laboratory is provided. The issuer of the sound pressure test reservation instruction is the engineer or technician of the main laboratory. Since the technicians in the sound pressure room perform sound pressure testing in a multi-tasking manner, their work is supervised by the issuer. That is, when the issuer gives the sound pressure test reservation instruction, the sound pressure test software is in a startable state, and then the technicians in the sound pressure room can carry out the sound pressure test normally. In this way, the sound pressure test of the headphones can be more standardized and more controllable.

[0029] Furthermore, after receiving the sound pressure test reservation instruction, the sound pressure test software in the slave device switches from an unstartable state to an startable state. During this process, the slave device is already turned on (the software may still not be turned on), and the technician, acting as a sound pressure test engineer, receives the sound pressure test reservation instruction in the sound pressure room, and the sound pressure test software switches from an unstartable state to a startable state.

[0030] In one embodiment, step S2 includes: S21, obtaining a first sound pressure level (SPL) detection result when the earphone under test is in working state for the first time; S22, obtaining a second SPL detection result when the earphone under test is in working state for the second time; S23, obtaining an incremental SPL detection result set when the earphone under test is in working state subsequently; and S24, processing the first SPL detection result, the second SPL detection result, and the incremental SPL detection result set according to a preset SPL rule to obtain a SPL calculation result. The incremental SPL detection result set includes at least three SPL detection results, and the SPL calculation result should ideally be based on a massive amount of SPL detection results; therefore, the above solution combines both professionalism and efficiency.

[0031] In one embodiment, the control unit is connected to a sensing unit, which is located on the simulated ear of the head-body simulation device; step S21 includes: S501, sensing the state of the sensing unit of the head-body simulation device to determine whether the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S502, if the head-body simulation device in the sound pressure chamber is not in the state of wearing the earphone under test, keeping the detection interface of the host in the main laboratory in the locked interface; S503, if the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test, that is, the earphone under test is in the working state for the first time, unlocking the detection interface of the host in the main laboratory to the active interface; S504, receiving the first sound pressure detection command from the slave device in the sound pressure chamber, and continuously for a preset standard time to obtain the first sound pressure detection result; S505, after obtaining the first sound pressure detection result, controlling the detection interface of the host in the main laboratory to switch back to the locked interface.

[0032] In the above scheme, the control unit is connected to the sensing unit, which is located on the simulated ear of the head-body simulation device. The location of the sensing unit is a hardware feature, corresponding to the part of the ear that can feel pressure after wearing the headphones, such as the outer ear, the concha, or other parts of the ear. The specific location is determined by the ability to sense the headphones being worn. This is something that an engineer in the art will understand. Furthermore, if the head-body simulation device in the sound pressure chamber is in the headphone-wearing state, it indicates that the technicians have placed the headphones, meaning the process has been completed according to specifications.

[0033] In the above scheme, the continuously preset standard time, i.e., the necessary duration for sound pressure detection, should not be too short (e.g., only a few seconds). The specific duration is understandable to engineers in the field, and the technical team can also set it according to requirements. Furthermore, after obtaining the first sound pressure detection result, the detection interface of the main laboratory host switches back to the locked interface; specifically, this can be a direct intelligent switch after obtaining the first sound pressure detection result.

[0034] In one embodiment, step S22 includes: S601, determining whether the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S602, if the head-body simulation device in the sound pressure chamber is not in the state of wearing the earphone under test, keeping the detection interface of the main unit in the main laboratory locked; S603, if the head-body simulation device in the sound pressure chamber is in the state of wearing the earphone under test, that is, the earphone under test is in working state for the second time, unlocking the detection interface of the main unit in the main laboratory and putting it in the active interface; S604, receiving the second sound pressure detection command from the slave device in the sound pressure chamber, and continuously for a preset standard time to obtain the second sound pressure detection result; S605, after obtaining the second sound pressure detection result, controlling the detection interface of the main unit in the main laboratory to switch back to the locked interface. In this process, technicians perform the first sound pressure test, the second sound pressure test, and so on up to the Nth sound pressure test on the same earphone, and then combine the values ​​from each test to obtain the "sound pressure calculation result"; in S601, it is not necessary to determine whether it is the same earphone, because the second test data (not a new earphone) will definitely not deviate much from the first one; if the deviation is too large, it will obviously not meet the requirements.

[0035] In the above scheme, if the head and body simulation device in the sound pressure chamber is not in the state of wearing the headphones under test, the detection interface of the main unit in the main laboratory is kept in the locked interface. That is, after switching from the locked interface to the active interface, it has now returned to the locked interface.

[0036] In one embodiment, step S23 includes: S701, determining whether the head and body simulation device in the sound pressure chamber is in the state of wearing the earphone under test; S702, referring to the pattern of steps S502 to S505, sequentially obtaining at least three sound pressure detection results when the earphone under test is subsequently in the working state, and after obtaining the results, switching back to the locking interface, and taking at least three sound pressure detection results as an incremental sound pressure detection result set.

[0037] In the above scheme, at least three sound pressure level detection results belong to the same category as the first and second sound pressure level detection results. For example, at least three sound pressure level detection results can be the third, fourth, and fifth sound pressure level detection results. Furthermore, the set of incremental sound pressure level detection results can be a direct set of the third, fourth, and fifth sound pressure level detection results. This definition is understood by those skilled in the art and does not refer to numerical superposition.

[0038] During routine reviews, the inventors discovered that raw sound pressure level (SPL) measurement records were prone to confusion or incompleteness. A key reason for this was the stringent requirements for SPL chamber space. Given the limited space in the main laboratory, most SPL chambers needed to be set up separately (not physically adjacent to the main laboratory). Therefore, the management standards of the main laboratory were not easily extended to the SPL chambers. Furthermore, technical personnel were not permanently stationed in the SPL chambers; they only entered when necessary, wearing headphones, further contributing to the inconsistency of the raw records. Based on this, the solution described in this application addresses scenarios where SPL measurement is performed in a physical distance from the main laboratory. It allows the main laboratory to remotely monitor the SPL chamber, defining the starting point for a single SPL measurement as the sensing unit of the head-body simulation device, and the temporary endpoint as the host's detection interface switches back to the locked interface. This significantly improves both the reliability of the acquired SPL measurement results and the accuracy of the calculated SPL results.

[0039] In one embodiment, step S3 includes: S31, determining whether the digital handwriting of the original record corresponding to the sound pressure detection is recognized; S32, if the digital handwriting of the original record is recognized, filling the detection data result corresponding to the digital handwriting into the detection column of the host, and storing the detection data result in the detection column.

[0040] In the above scheme, after obtaining the first sound pressure level detection result, the second sound pressure level detection result, and the incremental sound pressure level detection result set, the technician needs to read the above results and then write an original record in the sound pressure chamber. The writing method is to directly handwrite with a pen, that is, digital handwriting (if the original record requires, it can also include sound pressure calculation results); that is, according to the table of the original record or the team's requirements, the digital handwriting includes, but is not limited to, the recorded data (sound pressure level detection results) or the calculated data (sound pressure level calculation results). Further, the detection data results corresponding to the digital handwriting are filled into the detection column of the host, where the digital handwriting is converted into detection data results (representing that the recognition of the handwriting has been completed); furthermore, the detection data results are the same as the numbers in the digital handwriting. Although there are requirements for the neatness of the numbers, it does not affect the inventive concept of this application.

[0041] In one embodiment, the present invention provides a sound detection system, wherein the control unit of the sound detection system is used to execute the sound pressure detection method as described in the above embodiment. The technical advantage of the sound detection system is that it makes the sound pressure detection of headphones more standardized and more controllable.

[0042] The sound pressure level (SPL) test of headphones requires simulating the process of headphones inside a listener's ear canal in order to evaluate the headphones' sound performance. This process requires the construction of a dedicated environment and supporting equipment such as head and body simulation devices to achieve a highly standardized and scientific test, that is, to simulate the acoustic environment of a real human wearing headphones as closely as possible. Based on this, the solution described in this application, through the control of the sound pressure level test software, can make the sound pressure level test of headphones more standardized and more controllable.

[0043] In summary, the solution described in this application addresses scenarios where there is a physical distance between the sound pressure chamber and the main laboratory during sound pressure testing. By having the main laboratory remotely monitor the sound pressure chamber, the starting point for a single sound pressure test is defined as the sensing unit of the head-body simulation device, and the temporary endpoint is defined as the host switching back to the locked interface. This not only significantly improves the reliability of the obtained sound pressure test results but also significantly increases the accuracy of the sound pressure calculation results.
