Description

Technical Field

[0001] The present invention relates to an abnormal sound detection device and an abnormal sound detection method used therein, and in particular to an abnormal sound detection device used to detect whether a peripheral interface device has an abnormal sound phenomenon and an abnormal sound detection method used therein. Background Art

[0002] Currently, various consumer electronic information or communication products on the market are becoming increasingly thinner and lighter, and most of them have various audio and video functions to meet people's consumption and entertainment needs.

[0003] As for laptop computers, their development trend is to become thinner and lighter, so the configuration of various internal components is getting closer to each other or against each other. For example, almost all general laptop computers are equipped with a peripheral interface device: a key mechanical structure for users to input keys; in addition, laptop computers also usually have a built-in sound device for sound playback, wherein the sound device is an active component including a plurality of speaker units, which is used to drive the plurality of speaker units to convert various normal sound signals (for example, music) into a vibration wave in a vibration manner, thereby generating sounds audible to the human ear.

[0004] Furthermore, due to the limitation of the internal space, the location of the aforementioned sound effect device is often close to the aforementioned key mechanical structure. Therefore, the vibration force generated by multiple speaker units (for example, the vibration force of the speaker unit caused by a certain frequency generated by a certain part of a certain song) will vibrate the various mechanical structures in the key mechanical structure that are passive components (for example, the scissor foot structure located under the key) to form a vibration sound wave. In this way, for some electronic products with abnormal assembly or design quality, it is easy to generate unexplained high-frequency resonant audio, and the human ear can often easily detect this abnormal sound phenomenon.

[0005] Therefore, how to timely detect the above-mentioned abnormal sounds such as high-frequency resonance audio with unknown causes during the production process of various thin and light electronic products and eliminate or improve them in advance has become a technical issue that the industry wants to solve.

[0006] Based on this, the industry currently generally uses a known abnormal sound detection device to detect the assembly quality status of electronic products during the production process; wherein, a vibration simulation mechanism in the known abnormal sound detection device can be used to accommodate a passive component to be detected (for example, a key mechanical structure belonging to a peripheral interface device), and then the vibration simulation mechanism will generate a corresponding vibration force according to an abnormal sound detection signal with certain specific detection frequencies, so that the peripheral interface device generates a vibration sound wave according to the vibration force, and then, a small number of audio collectors (for example, a single or a single row of microphones) are used to collect the vibration sound wave, and a vibration audio signal is generated, and finally the vibration audio signal is detected and analyzed to determine whether there is an abnormal sound phenomenon.

[0007] The problem with the known technology is that if the small amount of audio collectors used to collect the vibration sound waves and generate the vibration audio signals in the aforementioned known abnormal sound detection device are set in a fixed manner, since the distances between the positions of various areas in the passive component to be detected (for example, the keys arranged in different areas in the key mechanical structure) and the aforementioned fixed audio collectors are different from each other, the collected vibration audio signals are not easy to finely distinguish the various areas of the passive component to be detected that actually generate the abnormal sound. Or, the sound collection coverage of the aforementioned fixed audio collector may be inconsistent with the size of the passive component to be detected, resulting in the problem of some abnormal sounds being missed.

[0008] In order to solve the above situation, the setting mode of the known abnormal sound detection device is changed to collect the vibration audio signal in a movable manner to ensure that the full-size area of ​​the passive component to be detected can be detected. However, one of the costs of adopting this mobile audio collector is that the cost is relatively high, and the control and moving mechanisms will become more complicated.

[0009] Based on this, a known abnormal sound detection device that is fixed and distributed in a matrix manner has been introduced in order to overcome the above-mentioned problems of complex control and movement mechanisms and incomplete sound reception. However, the defect of this known method is that since it is a known abnormal sound detection device that is distributed in a matrix manner, the vibration audio signals generated by the multiple audio collectors therein have an astonishingly large number of overall signals. If they are to be further synchronously input and abnormal sound analysis is to be performed at the same time, the overall analysis workload will be very large. On the other hand, how to avoid or reduce the noise in such a large number of collected vibration audio signals will also be a very difficult problem.

[0010] Therefore, how to more efficiently perform hardware control and vibration audio signal collection for the abnormal sound detection device distributed in a matrix manner, and how to more accurately analyze the collected vibration audio signals to reduce the difficulty and cost of abnormal sound analysis, have become the main technical issues to be solved by the present invention.

In addition, the drawings in the embodiments omit unnecessary elements or elements that can be completed by conventional techniques to clearly show the technical features of the invention.

[0072] See also Figure 1 , which is a conceptual diagram of a preferred embodiment of the present invention. In addition, please refer to Figure 2A , which is Figure 1 A specific implementation concept diagram of the signal composition of the abnormal sound detection signal in the preferred embodiment of the present invention; that is, Figure 1 In the present invention, an abnormal sound detection device 10 is used to detect a peripheral interface device D (for example, a key mechanical structure); wherein the abnormal sound detection device 10 at least includes: a vibration simulation mechanism 11, an audio collection device 12 having at least a plurality of audio collectors 121 and an audio collection unit selector 122, and a control and analysis device 13.

[0073] In a preferred embodiment, the vibration simulation mechanism 11 comprises: a detection platform 111 , a mechanism body 112 that can accommodate the key mechanical structure D, a vibration generator 113 adjacent to the mechanism body 112 , and a driver and amplifier 114 .

[0074] The mechanism body 112 is disposed on the detection platform 111 via a plurality of vibration-proof elements 115 , and the plurality of vibration-proof elements 115 disposed between the detection platform 111 and the mechanism body 112 can be used as a buffer structure between the detection platform 111 and the mechanism body 112 .

[0075] In addition, the mechanism body 112 at least includes a top cover 1121 and a base 1122, so that the key mechanical structure D is disposed between the top cover 1121 and the base 1122; wherein, in a preferred approach, the vibration generator 113 can be disposed adjacent to or attached to the base 1122, but the present invention is not limited thereto.

[0076] Furthermore, the control and analysis device 13 is used to output an abnormal sound detection signal T to control the vibration simulation mechanism 11 to generate a vibration force, so that the key mechanical structure D generates a vibration sound wave V according to the vibration force; wherein the drive and amplifier 114 is used to receive a plurality of abnormal sound detection sub-signals T1-T6 (such as test signals T112-T612) in the abnormal sound detection signal T respectively. Figure 2A ), and after amplifying the signal, transmit it to the vibration generator 113, so that it generates a vibration force, and the key mechanical structure D generates the vibration sound wave V according to the vibration force.

[0077] Of course, another preferred embodiment of the present invention is to change the location of the driver and amplifier 114 in the control and analysis device 13 (not shown), and the present invention is not limited thereto.

[0078] One of the technical features of the present invention is that the audio collecting device 12 having multiple audio collectors 121 and the audio collecting unit selector 122 is arranged close to the mechanism body 112, and wherein the multiple audio collectors 121 are divided into at least two groups of audio collecting units, correspondingly distributed and close to at least two groups of different area positions of the key mechanical structure D, so as to collect the vibration sound wave V, and enable the audio collecting device 12 to generate a vibration audio signal S for the control and analysis device 13 to input the vibration audio signal S to detect and distinguish whether there is any abnormal sound phenomenon therein.

[0079] For more information, please see Figure 2B , which is Figure 1 A three-dimensional example diagram of a specific implementation of multiple audio collectors 121 in a preferred embodiment of the present invention; Figure 2B In the embodiment, any audio collector 1211 among the multiple audio collectors 121 may be any one of a microphone, a sound guide tube and a patch-type sound receiving element.

[0080] In addition, multiple audio collectors 121 are distributed in a matrix manner; wherein, any column of audio collectors (for example, each column has 8 audio collectors 1211) or any row of audio collectors (for example, each row has 6 audio collectors 1211) among the multiple audio collectors 121 distributed in the matrix can be regarded as a group of audio collection units, and taking the preferred implementation concept of the present invention as an example, it can be divided into six groups of audio collection units U1~U6 as an example for subsequent description, but the present invention is not limited to this.

[0081] Furthermore, in order to prevent the control and analysis device 13 from receiving too many input signals at one time, the control and analysis device 13 will prioritize the output of the abnormal sound detection signal T and arrange a plurality of abnormal sound detection sub-signals T1 to T6 (such as Figure 2A As shown in the figure), in this way, the control and analysis device 13 can use multiple audio collection unit selection signals T111~T611 to control the audio collection unit selector 122 at different times, so that the audio collection unit selector 122 can selectively enable different groups of audio collection units among the multiple audio collection units U1~U6 in turn according to and with priority.

[0082] At the same time, since the vibration generator 13 can also generate a corresponding vibration force according to any one of the multiple test signals T112~T612, and the key mechanical structure D can also generate a corresponding vibration sound wave V according to the corresponding vibration force, at this time, for any group of audio collection units among the multiple audio collection units U1~U6 that are in a consistent energy state, one of the corresponding vibration audio unit signals S1~S6 can be generated in sequence; and the multiple vibration audio unit signals S1~S6 generated in sequence at different times can be arranged in a series to form the vibration audio signal S.

[0083] Please see again Figure 2A A specific implementation concept example diagram of the signal composition of the abnormal sound detection signal T, combined with the above description, can be seen that according to the six groups of audio collection units U1~U6 exemplified by the present invention, the abnormal sound detection signal T can be arranged to be composed of six abnormal sound detection sub-signals T1~T6, so as to perform respective abnormal sound detection procedures through different audio collection units at different times; wherein, the plurality of abnormal sound detection sub-signals T1~T6 respectively preferably include six plurality of audio collection unit selection signals T111~T611, and six plurality of test signals T112~T612 are arranged immediately after the plurality of audio collection unit selection signals T111~T611. Of course, the plurality of audio collection unit selection signals T111~T611 and the plurality of test signals T112~T612 can also respectively constitute six audio collection unit selection and test signals T11~T61.

[0084] Among them, any one of the multiple test signals T112~T612 can be one of a sweep test signal and a pink noise test signal; wherein the sweep test signal refers to a test signal in which the test frequency range gradually increases from zero to 20KHZ or gradually decreases from 20KHZ to zero within a certain time range, and the pink noise test signal refers to a mixed test signal of 0~20KHz with a power spectral density (PSD) that is higher at low frequencies and decreases from low frequencies to high frequencies; and the test signal used in the present invention is not limited to the sweep test signal or the pink noise test signal.

[0085] From the signal arrangement of the abnormal sound detection signal T described above, it can be seen that the abnormal sound detection device 12 distributed in a matrix manner of the present invention can perform more efficient hardware control by selectively enabling different groups of audio collection units in a plurality of audio collection units U1 to U6 in turn, and collect and analyze the vibration audio signal S in sequence.

[0086] For a more detailed description of the specific embodiments of the present invention, please refer to Figure 3 , which is Figure 1 A specific implementation concept diagram of the audio collection device 12 and the control and analysis device 13 in a preferred embodiment of the present invention is shown in conjunction with the aforementioned Figures 1 to 2B shown; Figure 3 In further Figure 2B The multiple audio collectors 121 shown are divided into six groups of audio collection units U1-U6, which are used to be implemented together with the audio collection unit selector 122 as a conceptual example.

[0087] Furthermore, a preferred method for the control and analysis device 13 may include: a storage module 131, electrically connected to the audio collection device 12, the storage module 131 is used to input and store multiple vibration audio unit signals S1~S6; a control and processing module 132, electrically connected to the storage module 131, the vibration simulation mechanism 11 and the audio collection device 12, the control and processing module 132 is used to control and generate multiple abnormal sound detection sub-signals T1~T6 to the audio collection device 12 and the vibration simulation mechanism 11, and input multiple vibration audio unit signals S1~S6; and an analysis and detection module 133, electrically connected to the control and processing module 132, the analysis and detection module 133 is used to detect and distinguish whether any one of the multiple vibration audio unit signals S1~S6 has an abnormal sound phenomenon.

[0088] A preferred approach is that any one of the control and processing module 132 and the analysis and detection module 133 can be implemented in a full hardware manner, or in a firmware manner, or in a hardware-software combination (e.g., APP) manner, and the present invention is not limited thereto.

[0089] In addition, to further improve the processing efficiency, the analysis and detection module 133 may also include eight analysis and detection submodules 1331-1338 to analyze the audio data collected from a plurality of audio collectors in each column (for example, Figure 2B and Figure 3 In the embodiment, each column has a total of 8 audio collectors 1211) and any of the multiple vibration audio unit signals S1~S6 corresponding to them are subjected to synchronous abnormal sound analysis. That is to say, multiple analysis and detection sub-modules 1331~1338 are used to synchronously detect and distinguish whether the output signals generated by each of the 8 audio collectors 1211 in each column have abnormal sound phenomena.

[0090] In addition, please refer to the other preferred configuration of the abnormal sound detection signal T in the present invention. Figure 2A; Among them, multiple abnormal sound detection sub-signals T1~T6 can further include corresponding synchronization signals T12~T62 respectively; that is to say, behind the multiple test signals T112~T61, a synchronization signal T12~T62 is respectively set immediately, so that the analysis and detection module 133 can identify and analyze the test signal adjacent to one of the multiple synchronization signals T12~T62 according to one of the multiple synchronization signals T12~T62, and after it is input into the vibration simulation mechanism 11, the audio collection device 12 generates a vibration audio recognition effective section in the corresponding vibration audio unit signal, and determines whether the vibration audio recognition effective section has an abnormal sound phenomenon.

[0091] For example, the analysis and detection module 133 can be based on the synchronization signal T22, and only needs to identify and analyze the test signal T212 (which can be one of the swept frequency test signal and the pink noise test signal) that is adjacent to and in front of the synchronization signal T22. After being input into the vibration simulation mechanism 11, the audio collection device 12 generates a corresponding vibration audio unit signal S2 in a vibration audio identification effective section, and determines whether the vibration audio identification effective section has an abnormal sound phenomenon. In this way, when performing abnormal sound analysis, the present invention can effectively eliminate other noises in the corresponding vibration audio unit signal S2 collected and output by the second group of audio collection units U2 that are also selected and enabled.

[0092] In other words, the signal composition of any one of the multiple abnormal sound detection sub-signals T1~T6 sequentially includes at least one of the multiple audio collection unit selection signals T111~T611, one of the multiple test signals T112~T612, and one of the multiple synchronization signals T12~T62.

[0093] Of course, the aforementioned audio collection device 12 can be a fixed audio collection device, but in order to further improve the resolution of the recognition analysis, the aforementioned audio collection device 12 can also be changed into a mobile audio collection device.

[0094] Based on the above description and the above Figures 1 to 3 See Figure 4A and Figure 4B , which is a method for detecting abnormal sound of the present invention, applied to detecting the peripheral interface device D, and at least comprising the following steps:

[0095] Step P0: Start;

[0098] Step P3: According to the abnormal sound detection signal T, the audio collection device 121 selectively enables different groups of audio collection units among the at least two groups of audio collection units U1-U6 in turn at different times; wherein the abnormal sound detection signal T is composed of at least two abnormal sound detection sub-signals T1-T6 arranged in a series;

[0099] Step P4: according to the abnormal sound detection signal T, the vibration simulation mechanism 11 generates the vibration force, and the peripheral interface device D generates the vibration sound wave V according to the vibration force;

[0100] Step P5: using different groups of audio collection units U1-U6 in a selection enabled state at different times to respectively collect the vibration sound wave V, and respectively generate and output the corresponding vibration audio unit signals S1-S6; wherein the plurality of vibration audio unit signals S1-S6 are arranged in series to form the vibration audio signal S; and

[0101] Step P6: Perform corresponding abnormal sound analysis procedures according to the multiple vibration audio unit signals S1-S6 respectively.
